                                     SUMMARY

       This  summary  highlights  some of the  information  in this  prospectus.
Because it is a summary,  it does not contain all of the information you need to
make an investment decision.  To understand this offering fully, you should read
this entire prospectus.

                          Altair Nanotechnologies Inc.

         We are a  development-stage  Canadian company whose primary business is
developing  and  commercializing  ceramic oxide  nanoparticle  products.  In the
second quarter of 2002, we initiated  research and development  efforts directed
toward the utilization of nanomaterials in the pharmaceuticals industry. In July
2002, we announced the development of a new active pharmaceutical ingredient for
the treatment of hyperphosphatemia (elevated serum phosphate levels) in patients
undergoing  kidney  dialysis,  as  well  as a new  drug  delivery  system  using
inorganic ceramic  nanoparticles.  In August 2002, we filed a patent application
covering these  developments.  We are currently  seeking business  relationships
with   pharmaceutical   companies  that  can  conduct   additional  testing  and
development,  seek necessary FDA approvals and take the other steps necessary to
bring the new pharmaceutical ingredient and drug delivery system to market.

         In addition to  pharmaceuticals,  we are developing  nanomaterials with
potential   applications  in  alternative   energy--primarily   fuel  cells  and
batteries--as well as thermal spray coatings, catalysts, cosmetics and paints.

         We have also  developed  prototypes of the Altair  Centrifugal  Jig and
have  conducted  a  feasibility  study  on a  mining  property  that we lease in
Tennessee.  However,  we are not  further  developing  the jig or the  Tennessee
mineral property at this time.

         Our  principal  office is located at 1725 Sheridan  Avenue,  Suite 140,
Cody, Wyoming 82414 U.S.A., and our telephone number is (307) 587-8245.

                                                             risks.  You should read the risk  factors  beginning  on

                                  RISK FACTORS

       Before you invest in the offered securities described in this prospectus,
you should be aware that such  investment  involves  the  assumption  of various
risks. You should consider  carefully the risk factors  described below together
with all of the other information  included in this prospectus before you decide
to purchase the offered securities.

We have  not  generated  any  substantial  operating  revenues  and may not ever
generate substantial revenues.
--------------------------------------------------------------------------------
         To date, we have not generated substantial revenues from operations. As
of December 31, 2002, we have  generated  $268,041 of revenues from our titanium
processing  technology and $28,270 from use of the jig in consulting  contracts.
We have not completed  exploration  of the Tennessee  mineral  property.  We can
provide no assurance  that we will ever  generate  revenues  from the  Tennessee
mineral property or that we will generate substantial revenues from the titanium
processing technology and the jig.

We may continue to experience significant losses from operations.
--------------------------------------------------------------------------------
         We have  experienced a loss from  operations in every fiscal year since
our inception. Our losses from operations in 2001 were $6,021,532 and our losses
from operations in 2002 were  $7,856,711.  Although we have made  projections of
possible one-time  profitability  during 2003, such projections are based solely
on an  expectation  that we will enter into a license  agreement with respect to
our new RenaZorb(TM) product and that such license agreement will include, among
other things, a one-time up-front multi-million dollar payment. We may not enter
into any such license  agreement,  or such license agreement may not involve any
significant  up-front  payments.  Even if we do receive a  significant  up-front
payment  during  2003 and achieve  one-time  profitability,  we will  thereafter
experience  a  net  operating  loss  until,  and  if,  the  titanium  processing
technology,  the jig and/or the  Tennessee  mineral  property  begin  generating
significant,  sustained  revenues.  Even if any or all such products or projects
begin generating  significant,  sustained revenues,  the revenues may not exceed
our costs of production and operating expenses.

We may not be able to raise sufficient capital to meet future obligations.
--------------------------------------------------------------------------------
                  As of  December  31,  2002,  we had  $244,681  in cash,  and a
working capital deficit of $204,365.  Although we have raised additional capital
since December 31, 2002, we do not expect that this capital,  when combined with
projected  revenues  from  nanoparticle  sales,  will be  sufficient to fund our
ongoing  operations.  Accordingly,  we will need to raise significant amounts of
additional  capital in the future in order to sustain our ongoing operations and
continue  the testing and  additional  development  work  necessary to place the
titanium processing technology into continuous  operation.  In addition, we will
need additional capital for exploration of the Tennessee mineral property. If we
determine to construct and operate a mine on the Tennessee mineral property,  we
will need to obtain a  significant  amount of  additional  capital  to  complete
construction of the mine and commence operations.

                                       4


         We may not be able obtain the amount of  additional  capital  needed or
may be forced to pay an extremely high price for capital.  Factors affecting the
availability and price of capital may include the following:

         o   market  factors  affecting  the  availability  and cost of  capital
             generally;
         o   our financial results;
         o   the amount of our capital needs;
         o   the  market's  perception  of mining,  technology  and/or  minerals
             stocks;
         o   the economics of projects being pursued;
         o   industry perception of our ability to recover minerals with the jig
             or titanium  processing  technology or from the  Tennessee  mineral
             property; and
         o   the price, volatility and trading volume of our common shares.

         If we are  unable to obtain  sufficient  capital or are forced to pay a
high  price  for  capital,  we may be  unable  to  meet  future  obligations  or
adequately  exploit  existing  or  future  opportunities,  and may be  forced to
discontinue operations.

We  have a  substantial  number  of  warrants,  options  and  other  convertible
securities  outstanding and may issue a significant  number of additional shares
upon exercise or conversion thereof.
--------------------------------------------------------------------------------
         As of December 31, 2002, there were outstanding warrants to purchase up
to 9,170,171  common shares at a weighted  average  exercise  price of $1.92 per
share and  options  to  purchase  up to  4,061,700  common  shares at a weighted
average  exercise  price of $3.83 per share.  The existence of such warrants and
options may hinder  future equity  offerings,  and the exercise of such warrants
and options may further dilute the interests of all shareholders.  Future resale
of the common  shares  issuable on the exercise of such warrants and options may
have an adverse effect on the prevailing market price of the common shares.

         In addition,  we have issued a Second Amended and Restated Secured Term
Note.  Under the Second  Amended and  Restated  Secured  Term Note, a conversion
right with  respect to $280,000 of  principal  accrues on each of March 1, 2003,
June 1, 2003,  September  1, 2003,  December  1, 2003 and March 1, 2004.  If the
amount that would be subject to a conversion  right is prepaid prior to the date
of accrual,  such conversion right does not accrue.  Once a conversion right has
accrued, the principal amount subject to that conversion right cannot be prepaid
unless all principal amounts not subject to a conversion right have been prepaid
in full. Each conversion right gives the holder the right to convert the subject
principal amount into common shares at a conversion price equal to the lesser of
(a)  $1.00  per share and (b) 70% of the  average  of the  closing  price of our
common  shares for the five trading  days ending on the trading day  immediately
preceding the date on which that conversion right accrued.

         In order to illustrate the relationship between the market price of our
common  shares and the issuance of common shares upon the exercise of conversion
rights that may accrue under the Second Amended and Restated  Secured Term Note,
the following table sets forth how many additional common shares would be issued
upon the exercise of such conversion rights if such conversion rights accrue and
the average of the closing  price of our common  stock for the five trading days
ending on the day before each conversion  right accrues is (a) $1.43 or greater,
(b) $0.50 per share, (c) $0.25 per share,  and (d) $0.10 per share.  Such prices


                                       5


are  selected  for  illustration  purposes  only and do not  reflect  our actual
estimate  of the  average  of the  closing  price of our  common  shares for any
particular period.



                                      $1.43 or         $0.50           $0.25             $0.10

         (1) Assumes that  shareholder  approval is obtained for the transaction
         in which we issued the Second  Amended and  Restated  Secured Term Note
         and all related  transactions,  that no principal is prepaid,  that all
         conversion rights accrue and are exercised at the same time and that no
         default  occurs and that no  penalties  or premiums  are required to be
         paid.

         (2)  Represents  percentage  of  outstanding  common  shares  following
         exchange assuming the 30,244,348 common shares  outstanding on December
         31, 2002 are outstanding on the date of conversion.

The  potential  accrual  of such  conversion  rights may  hinder  future  equity
offerings,  and the  exercise of any  conversion  rights that accrue may further
dilute the interests of all shareholders.  The sale in the open market of common
shares  issuable  upon the  exercise  of  conversion  rights may place  downward
pressure  on the market  price of our common  shares.  Speculative  traders  may
anticipate the exercise of conversion  rights and, in  anticipation of a decline
in the market  price of our common  shares,  engage in short sales of our common
shares. Such short sales could further negatively affect the market price of our
common shares.

Our  competitors  may be able to raise  money  and  exploit  opportunities  more
rapidly, easily and thoroughly than we can.
--------------------------------------------------------------------------------
         We have limited financial and other resources and, because of our early
stage of development,  have limited access to capital. We compete or may compete
against entities that are much larger than we are, have more extensive resources
than we do and have an established reputation and operating history.  Because of
their size,  resources,  reputation,  history and other factors,  certain of our
competitors  may have better access to capital and other  significant  resources
than we do and, as a result, may be able to exploit  acquisition and development
opportunities more rapidly, easily or thoroughly than we can.

We have  pledged  substantial  assets to secure the Second  Amended and Restated
Secured Term Note.
--------------------------------------------------------------------------------
         We have  pledged all of the  intellectual  property,  fixed  assets and
common  stock  of  Altair  Nanomaterials,  Inc.,  our  second-tier  wholly-owned
subsidiary,  to secure  repayment of a Second Amended and Restated  Secured Term
Note with a face value of  $1,400,000  and a due date of March 31, 2004.  Altair
Nanomaterials,  Inc.  owns and operates the titanium  processing  technology  we
acquired from BHP Minerals  International  Inc. in 1999.  The Second Amended and
Restated  Secured  Term Note is also secured by a pledge of the common stock and
leasehold assets of Mineral Recovery Systems,  Inc., which owns and operates our
leasehold  interests in the Camden,  Tennessee area. If we default on the Second
Amended and Restated Secured Term Note, severe remedies will be available to the
holder of the Second Amended and Restated Secured Term Note, including immediate
seizure and disposition of all pledged assets.

                                       6


We have  issued a  $3,000,000  note to secure the  purchase  of the land and the
building where our titanium processing assets are located.
--------------------------------------------------------------------------------
         In August 2002, we entered into a purchase and sale  agreement with BHP
Minerals International Inc. to purchase the land, building and fixtures in Reno,
Nevada where our titanium processing assets are located. In connection with this
transaction,  BHP also  agreed to  terminate  our  obligation  to pay  royalties
associated  with  the  sale or use of the  titanium  processing  technology.  In
return, we issued to BHP a note in the amount of $3,000,000, at an interest rate
of 7%,  secured by the  property we acquired.  The first  payment of $600,000 of
principal plus accrued interest is due February 8, 2006.  Additional payments of
$600,000  plus  accrued  interest  are due  annually on February 8, 2007 through
2010. If we fail to make the required payments on the note, BHP has the right to
foreclose and take the property.  If this should occur,  we would be required to
relocate  our titanium  processing  assets and  offices,  causing a  significant
disruption in our business.

Operations using the titanium  processing  technology,  the jig or the Tennessee
mineral property may lead to substantial environmental liability.
--------------------------------------------------------------------------------
         Virtually any proposed use of the titanium processing  technology,  the
jig or the Tennessee  mineral  property  would be subject to federal,  state and
local  environmental  laws.  Under such laws,  we may be jointly  and  severally
liable with prior property owners for the treatment, cleanup, remediation and/or
removal of any  hazardous  substances  discovered  at any  property  we use.  In
addition,  courts or government  agencies may impose  liability for, among other
things,   the  improper   release,   discharge,   storage,   use,   disposal  or
transportation of hazardous  substances.  We might use hazardous substances and,
if we do, we will be subject to substantial risks that environmental remediation
will be required.

Certain of our experts and  directors  reside in Canada and may be able to avoid
civil liability.
--------------------------------------------------------------------------------
         We are a Canadian corporation,  and a majority of our directors and our
Canadian  legal counsel are residents of Canada.  As a result,  investors may be
unable to effect  service of process upon such persons  within the United States
and may be unable to enforce  court  judgments  against such persons  predicated
upon civil  liability  provisions  of the United States  securities  laws. It is
uncertain  whether Canadian courts would (i) enforce  judgments of United States
courts  obtained  against us or such directors,  officers or experts  predicated
upon the civil  liability  provisions of United States  securities  laws or (ii)
impose liability in original  actions against Altair or its directors,  officers
or experts predicated upon United States securities laws.

We are dependent on key personnel.
--------------------------------------------------------------------------------
         Our  continued  success  will  depend  to a  significant  extent on the
services of Dr. William P. Long, our Chief Executive  Officer,  Dr. Rudi Moerck,
our President,  and Mr. C. Patrick  Costin,  our Vice President and President of
Fine Gold  Recovery  Systems,  Inc.  and  Mineral  Recovery  Systems,  Inc.  our
wholly-owned  subsidiary.  The loss or unavailability of Dr. Long, Dr. Moerck or
Mr. Costin could have a material  adverse  effect on us. We do not carry key man
insurance on the lives of Dr. Long, Dr. Moerck or Mr. Costin.

                                       7


We may issue  substantial  amounts  of  additional  shares  without  stockholder
approval.
--------------------------------------------------------------------------------
         Our articles of  incorporation  authorize  the issuance of an unlimited
number of common  shares.  All such  shares may be issued  without any action or
approval by our stockholders.  In addition, we have two stock option plans which
have  potential for diluting the ownership  interests of our  stockholders.  The
issuance of any  additional  common shares would further  dilute the  percentage
ownership of Altair held by existing stockholders.

The market price of our common shares is extremely volatile.
--------------------------------------------------------------------------------
         Our common shares are listed on the Nasdaq SmallCap Market.  Trading in
our common shares has been characterized by a high degree of volatility. Trading
in our common shares may continue to be characterized by extreme  volatility for
numerous reasons, including the following:

         o   Uncertainty  regarding  the  viability of the  titanium  processing
             technology, the jig or the Tennessee mineral property;
         o   Dominance  of  trading in our  common  shares by a small  number of
             firms;
         o   Positive or negative announcements by us or our competitors;
         o   Uncertainty  regarding  our ability to maintain  our listing on the
             Nasdaq SmallCap Market and/or continue as a going concern;
         o   Industry trends,  general economic  conditions in the United States
             or  elsewhere,  or  the  general  markets  for  equity  securities,
             minerals, or commodities; and
         o   Speculation  by short sellers of our common shares or other persons
             who stand to profit from a rapid  increase or decrease in the price
             of our common shares.

We may be delisted from the Nasdaq SmallCap Market.
--------------------------------------------------------------------------------
         Our  listing  on the Nasdaq  SmallCap  Market is  conditioned  upon our
compliance with the NASD's  continued  listing  requirements  for such market by
June 2003, including the $1.00 per share minimum bid requirement.  If the market
price for our common shares has not increased to $1.00 per share for at least 10
consecutive days by June 2003, we expect to be delisted from the Nasdaq SmallCap
Market.  The  Staff of  Nasdaq  has  indicated  that it may  submit to the SEC a
proposed rule or policy change which,  if approved by the SEC,  could lead to an
additional  180 day  extension  beyond  June 2003 in order to meet the $1.00 per
share minimum bid requirement for certain companies. Even if such change were to
be approved,  we would not likely be eligible for such  additional 180 extension
unless our we had a minimum  stockholders'  equity balance of $5,000,000 in June
2003. We presently do not have a stockholders' equity balance of $5,000,000 and,
absent a significant  infusion of capital,  do not expect to have such a balance
in June 2003.  Delisting from the Nasdaq  SmallCap Market may have a significant
negative  impact on the trading price,  volume and  marketability  of our common
shares.

                                       8


We have  never  declared  a cash  dividend  and do not  intend to declare a cash
dividend in the foreseeable future.
--------------------------------------------------------------------------------
         We have never declared or paid cash dividends on our common shares.  We
currently intend to retain any future earnings,  if any, for use in our business
and,  therefore,  do not anticipate paying dividends on our common shares in the
foreseeable future.

If you purchase shares in this offering, you will face immediate and substantial
dilution.
--------------------------------------------------------------------------------
         This offering involves  immediate  substantial  dilution to prospective
investors.  The book value per common share immediately  following this offering
will be substantially less than the price per common shares.

Because  we are not  required  to sell a minimum  number of  securities  in this
offering, there is a greater risk that you could lose your investment.
--------------------------------------------------------------------------------
         This offering is not subject to a requirement for the sale of a minimum
number of shares.  We cannot  assure you that we will be able to sell all or any
portion of the offered  shares and Series 2003A  Warrants or that  proceeds from
sales actually made will be sufficient to fund operations. Because the number of
offered  securities that we will actually sell in this offering is unknown,  the
risks  to  initial  purchasers  of  the  offered  securities  are  substantially
increased.

We may be unable to exploit  the  potential  pharmaceutical  application  of our
titanium processing technology.
--------------------------------------------------------------------------------
         We do not  have  the  technical  or  financial  resources  to  complete
development  of,  and take to  market,  any  pharmaceutical  application  of our
titanium  processing  technology.  In  order  for  us to  get  any  significant,
long-term  benefit  from  any  potential   pharmaceutical   application  of  our
technologies, the following must occur:

         o   we must enter into an evaluation  license or similar agreement with
             an existing  pharmaceutical  company under which such company would
             pay a fee for the right to  evaluate  a  pharmaceutical  use of our
             technology  for a  specific  period  of time and for an  option  to
             purchase or receive a license for such use of our technology;

         o   tests  conducted  by  such  pharmaceutical  company  would  have to
             indicate  that the  pharmaceutical  use of our  technology is safe,
             technically viable and financially viable;

         o   such pharmaceutical  company would have to apply for and obtain FDA
             approval  of  the  pharmaceutical  use of  our  technology,  or any
             related products, which would involve extensive additional testing;
             and

         o   such  pharmaceutical  company would have to successfully market the
             product incorporating our technology.

Although we may receive some significant  one-time payments in various stages of
the testing and evaluation of the pharmaceutical  application of our technology,


                                       9


we are not expecting to receive  significant ongoing revenue unless and until an
end product incorporating the technology goes to market.

We may not be able to  license  our  technology  for  titanium  dioxide  pigment
production.
--------------------------------------------------------------------------------
         Because of our relatively small size and limited  resources,  we do not
plan to use our titanium  processing  technology for  large-scale  production of
titanium  dioxide  pigments;  we have,  however,  entered into  discussions with
various minerals and materials  companies about licensing our technology to such
entities for large-scale  production of titanium dioxide  pigments.  We have not
entered into any long-term  licensing  agreements with respect to the use of our
titanium  processing  technology for large-scale  production of titanium dioxide
pigments  and can  provide no  assurance  that we will be able to enter into any
such an agreement.  Even if we enter into such  agreement,  we would not receive
significant  revenues  from such license until  feasibility  testing is complete
and, if the results of  feasibility  testing  were  negative,  would not receive
significant revenues at any time.

We may not be able to sell nanoparticles  produced using the titanium processing
technology.
--------------------------------------------------------------------------------
         We plan to use the titanium  processing  technology to produce titanium
dioxide  nanoparticles.  Titanium  dioxide  nanoparticles  and other products we
intend to initially produce with the titanium  processing  technology  generally
must be customized for a specific  application  working in cooperation  with the
end user. We are still testing and customizing our titanium dioxide nanoparticle
products  for various  applications  and have no long-term  agreements  with end
users to purchase any of our titanium dioxide nanoparticle  products.  We may be
unable to recoup  our  investment  in the  titanium  processing  technology  and
titanium processing equipment for various reasons, including the following:

         o   we may be unable to  customize  our titanium  dioxide  nanoparticle
             products to meet the distinct needs of potential customers;

         o   potential  customers  may  purchase  from  competitors  because  of
             perceived or actual quality or compatibility differences;

         o   our marketing and branding efforts may be insufficient to attract a
             sufficient number of customers; and

         o   because of our limited  funding,  we may be unable to continue  our
             development   efforts  until  a  strong  market  for  nanoparticles
             develops.

         In  addition,  the uses for such  nanoparticles  are  limited,  and the
market  for such  nanoparticles  is  small.  In light of the  small  size of the
market,  the addition of a single  manufacturer may cause the price to drop to a
point at which we cannot produce the nanoparticles at a profit.

Our costs of production may be too high to permit profitability.
--------------------------------------------------------------------------------
         We have not produced any mineral products using our titanium processing
technology and equipment on a commercial  basis.  Our actual costs of production
may exceed those of competitors  and, even if our costs of production are lower,


                                       10


competitors  may be able to sell titanium  dioxide and other products at a lower
price than is economical for Altair.

         In addition, even if our initial costs are as anticipated, the titanium
processing  equipment may break down, prove unreliable or prove inefficient in a
commercial  setting. If so, related costs, delays and related problems may cause
production  of  titanium  dioxide  nanoparticles  and  related  products  to  be
unprofitable.

We have not  completed  testing  and  development  of the jig and are  presently
focusing our resources on other projects.
--------------------------------------------------------------------------------
         We have not completed  testing of, or developed a production  model of,
any series of the jig. We do not expect to complete  testing and  development of
the jig during the coming year and have  determined to focus most of our limited
resources  on the  titanium  processing  technology.  We  may  never  develop  a
production model of the jig.

Even if we complete  development of the jig, the jig may prove  unmarketable and
may not perform as anticipated in a commercial operation.
--------------------------------------------------------------------------------
         The  designed  capacity  of the  Series  12 jig is too  small  for coal
washing, heavy minerals extraction,  and most other intended applications of the
jig,  except use in small placer gold mines or similar  operations.  Even if the
Series 12 jig is completed and performs to design  specifications  in subsequent
tests or at a  commercial  facility,  we  believe  that,  because  of its  small
capacity, the potential market for the Series 12 jig is limited.

         If we complete development of and begin marketing a production model of
the Series 30 jig, it may not prove  attractive to potential  end users,  may be
rendered obsolete by competing  technologies or may not recover end product at a
commercially  viable  rate.  Even if  technology  included in the jig  initially
proves attractive to potential end users,  performance  problems and maintenance
issues may limit the market for the jig.

The jig faces  competition  from other  jig-like  products and from  alternative
technologies.
--------------------------------------------------------------------------------
         Various   jig-like   products  and   alternative   mineral   processing
technologies  perform many functions similar or identical to those for which the
jig is designed. Results from further tests or actual operations may reveal that
these alternative  products and technologies are better adapted to any or all of
the uses for which the jig is intended.  Moreover,  regardless  of test results,
consumers may view any or all of such  alternative  products and technologies as
technically superior to, or more cost effective than, the jig.

Certain patents for the jig have expired, and those that have not expired may be
difficult to enforce.
--------------------------------------------------------------------------------
         All of the initial  patents issued on the jig have expired,  and we are
unable to prevent competitors from copying the technology once protected by such
patents. Additional patents related to the process through which water is pulsed
through the cylindrical  screen on the jig expire beginning in 2010, and patents


                                       11


for an efficiency-enhancing aspect of the cylindrical screen expire during 2018.
The cost of enforcing patents is often significant,  especially outside of North
America. Accordingly, we may be unable to enforce even our patents that have not
yet expired.

We have  suspended  examining the  feasibility  of mining the Tennessee  mineral
property and may not have working capital  sufficient to again continue  testing
efforts.
--------------------------------------------------------------------------------
         Due to a shortage of working  capital,  we have  suspended  feasibility
testing of the Tennessee mineral property.  We do not expect to obtain an amount
of  working  capital  sufficient  to  again  start  feasibility  testing  of the
Tennessee mineral property in the foreseeable future.

         Even if we again commence  feasibility testing on the Tennessee mineral
property,  we are unable to provide any  assurance  that mining of the Tennessee
mineral  property is feasible or to identify all processes that we would need to
complete  before we could commence a mining  operation on the Tennessee  mineral
property.  To the extent early feasibility  testing yields positive results,  we
expect feasibility testing to involve, among other things, the following:

         o   operating a pilot  mining  facility to determine  mineral  recovery
             efficiencies and the quality of end products;
         o   additional  drilling  and  sampling  in  order  to more  accurately
             determine the quantity,  quality and  continuity of minerals on the
             Tennessee mineral property;
         o   examining  production costs and the market for products produced at
             the pilot facility;
         o   designing any proposed mining facility;
         o   identifying and applying for the permits necessary for any proposed
             full-scale mining facility; and
         o   attempting to secure financing for any proposed  full-scale  mining
             facility.

Our test  production  at the  pilot  plant,  economic  analysis  and  additional
exploration activities may indicate any of the following:

         o   that the Tennessee mineral property does not contain heavy minerals
             of a  sufficient  quantity,  quality  or  continuity  to permit any
             mining;
         o   that production costs exceed anticipated revenues;
         o   that end  products  do not meet  market  requirements  or  customer
             expectations;
         o   that there is an insufficient  market for products minable from the
             Tennessee mineral property; or
         o   that  mining  the  Tennessee  mineral  property  is  otherwise  not
             economically or technically feasible.

         Even  if we  conclude  that  mining  is  economically  and  technically
feasible  on the  Tennessee  mineral  property,  we may be unable to obtain  the
capital, resources and permits necessary to mine the Tennessee mineral property.
Market  factors,  such as a decline  in the price  of, or demand  for,  minerals
recoverable  at  the  Tennessee  mineral  property,  may  adversely  affect  the
development  of mining  operations  on such  property.  In addition,  as we move
through the testing  process,  we may identify  additional items that need to be
researched and resolved before any proposed mining operation could commence.

                                       12


We cannot  forecast the life of any potential  mining  operation  located on the
Tennessee mineral property.
--------------------------------------------------------------------------------
         We have not explored and tested the Tennessee  mineral  property enough
to establish the existence of a commercially minable deposit (i.e. a reserve) on
such property.  Until such time as a reserve is established  (of which there can
be no  assurance),  we cannot  provide an estimate as to how long the  Tennessee
mineral property could sustain any proposed mining operation.

We may be  unable to  obtain  necessary  environmental  permits  and may  expend
significant resources in order to comply with environmental laws.
--------------------------------------------------------------------------------
         In order to begin  construction and commercial  mining on the Tennessee
mineral property, we must obtain additional federal, state and local permits. We
will also be required to conform our operations to the  requirements of numerous
federal,  state and local  environmental laws. Because we have not yet commenced
design of a commercial mining facility on the Tennessee mineral property, we are
not in a position  to  definitively  ascertain  which  federal,  state and local
mining  and  environmental  laws or  regulations  would  apply  to a mine on the
Tennessee  mineral property.  Nevertheless,  we anticipate having to comply with
and/or  obtain  permits  under the Clean Air Act,  Clean Water Act and  Resource
Conservation   and  Recovery  Act,  in  addition  to  numerous  state  laws  and
regulations  before  commencing  construction  or  operation  of a  mine  on the
Tennessee mineral property.  We can provide no assurance that we will be able to
comply with such laws and  regulations or obtain any such permits.  In addition,
obtaining  such  permits  and  complying  with  such   environmental   laws  and
regulations may be cost prohibitive.

The market for  commodities  produced using the jig or at the Tennessee  mineral
property may significantly decline.
--------------------------------------------------------------------------------
         If the jig is successfully  developed and  manufactured on a commercial
basis,  we intend  to use the jig,  or lease the jig for use,  to  separate  and
recover valuable,  heavy mineral particles.  Active international  markets exist
for gold, titanium,  zircon and many other minerals potentially recoverable with
the jig. Prices of such minerals  fluctuate widely and are beyond our control. A
significant  decline in the price of minerals  capable of being extracted by the
jig could have significant negative effect on the value of the jig. Similarly, a
significant  decline in the price of  minerals  expected  to be  produced on the
Tennessee  mineral  property  could have a  significant  negative  effect on the
viability of a mine or processing facility on such property.


                           FORWARD-LOOKING STATEMENTS

       This  prospectus  contains  various  forward-looking   statements.   Such
statements  can  be  identified  by  the  use  of  the   forward-looking   words
"anticipate," "estimate," "project," "likely," "believe," "intend," "expect," or
similar words. These statements discuss future expectations, contain projections
regarding future developments,  operations,  or financial  conditions,  or state
other  forward-looking   information.   When  considering  such  forward-looking
statements,  you  should  keep in mind the risk  factors  noted in the  previous
section and other  cautionary  statements  throughout  this  prospectus  and our
periodic  filings with the SEC that are  incorporated  herein by reference.  You
should  also  keep in mind  that all  forward-looking  statements  are  based on


                                       13


management's  existing  beliefs  about  present  and  future  events  outside of
management's  control and on assumptions that may prove to be incorrect.  If one
or  more  risks  identified  in  this  prospectus  or  any  applicable   filings
materializes,  or any other underlying  assumptions prove incorrect,  our actual
results may vary materially from those  anticipated,  estimated,  projected,  or
intended.

       Among the key  factors  that may have a direct  bearing on our  operating
results are risks and  uncertainties  described under "Risk Factors,"  including
those attributable to the absence of significant  operating revenues or profits,
uncertainties  regarding the development and  commercialization  of the titanium
processing  technology  and the  jig,  development  risks  associated  with  the
Tennessee  mineral  property and  uncertainties  regarding our ability to obtain
capital  sufficient to continue our operations and pursue our proposed  business
strategy.

                                 USE OF PROCEEDS

         We will  receive  all of the  proceeds  from the  offer and sale of the
offered  securities.  We  intend  to use the net cash  proceeds,  following  the
payment of any legal  costs and other  offering  expenses,  to  provide  working
capital to be used for general corporate purposes. If management determines that
capital from other sources is sufficient to fund our ongoing operations,  we may
use up to $280,000 of the net cash proceeds to prepay indebtedness arising under
our $1,400,000  Second Amended and Restated Secured Term Note. The interest rate
of this note is 11% per year.  Under such note, a conversion  right with respect
to  $280,000  of  principal  accrues  on each of March 1,  2003,  June 1,  2003,
September 1, 2003,  December 1, 2003 and March 1, 2004. If the amount that would
be subject to a conversion  right is prepaid prior to the date of accrual,  such
conversion right does not accrue. In order to avoid the dilution associated with
the accrual of such a conversion  right,  management  may determine to use up to
$280,000  of the net  cash  proceeds  in  order  to  prevent  the  accrual  of a
conversion right on June 1, 2003 or September 1, 2003.

         In addition, in order to conserve working capital, we may issue some or
all of the offered  securities  in  non-cash  transactions  in exchange  for the
cancellation of indebtedness  and accounts payable and in exchange for services,
including services rendered in connection with capital raising activities.

         There is no requirement that we sell a minimum number of shares in this
offering.  Therefore,  we  may  receive  no  proceeds  from  this  offering,  or
insufficient proceeds for our planned use of proceeds set forth above.

                                    DILUTION

         Our net  tangible  book  value  (deficit)  at  December  31,  2002  was
$3,258,613 or approximately $0.11 per common share. Net tangible book value of a
company  is the  value of all of its  tangible  assets,  less  the  value of all
liabilities.  Net tangible  book value per common share is the net tangible book
value  of the  company  divided  by the  number  of  common  shares  issued  and
outstanding.

         If all of the 1,500,000 common shares and 750,000 Series 2003A Warrants
to which this prospectus  relates are sold at an assumed sale price of $0.40 per
share,  and all Series 2003A Warrants are exercised at an assumed exercise price
of $1.00 per share, our net tangible book value would be $4,608,613 or $0.14 per
common  share at December 31,  2002,  resulting in an immediate  increase in net
tangible  book value of $1,350,000  or  approximately  $0.03 per common share to
existing  shareholders  and an  immediate  dilution of  approximately  $0.46 per
common share to purchasers.

         The following table illustrates  dilution on a per common share and per
offering basis:



                                                                              Per Unit         Per Offering
                                                                              --------         ------------

Pro forma net tangible book value dilution to new investors (3)............     $0.46           $1,030,887


     (1) Reflects the sale of 1,500,000  common shares and 750,000  Series 2003A
         Warrants at an estimated  purchase  price per units of one common share
         and one-half  Series 2003A Warrant of $0.40.  The actual purchase price
         will vary, and may differ materially, from the estimated price.

     (2) Assumes that the number of common shares outstanding as of December 31,
         2002 was  30,244,348  and that the 1,500,000  common shares and 750,000
         Series 2003A  Warrants to which this  prospectus  relates are sold at a
         price of  $0.40  per  share  and that all  Series  2003A  Warrants  are
         exercised for the purchase of an additional 750,000 common shares at an
         exercise  price of $1.00  per  share.  Does not  reflect  the  possible
         issuance  of up  to  4,061,700  common  shares  upon  the  exercise  of
         outstanding  stock options or the possible  issuance of up to 9,170,177
         common shares upon the exercise of outstanding warrants.

     (3) Dilution represents the difference between the amount paid by investors
         (average  price of $0.60 per share) and the pro forma net tangible book
         value after the offering contemplated by this prospectus.

                              PLAN OF DISTRIBUTION

              We are  offering  and  selling  the  1,500,000  common  shares and
750,000  Series  2003A  Warrants to which this  prospectus  relates  directly to
purchasers. We have not retained any underwriter, broker or dealer to facilitate
the offer or sale of the  offered  securities,  and we will pay no  underwriting
commissions  or  discounts in  connection  with the offer or sale of the offered
securities.  The offered  securities  will be offered  directly  to  prospective
investors  by our  President,  Rudi  E.  Moerck,  and by  the  President  of our
wholly-owned subsidiary Altair Nanomaterials, Inc, Kenneth E. Lyon. In addition,
some of our other  officers  and  employees  may  prepare  and  deliver  written

broker-dealer.  In  order to be able to offer  and sale the  offered  securities
without being  associated with a registered  broker dealer,  Messrs.  Moerck and
Lyon are relying upon the safe harbor set forth in Rule 3a4-1  promulgated under

forth in Rule 3a4-1, an associated person of the issuer must satisfy each of the
following requirements:

     (1) The associated person is not subject to statutory  disqualification  at
         the time of his participation in the offering.  In general, a person is

         Association  of  Securities  Dealers),  has  had  a  securities-related
         registration  revoked or is barred to trading in certain  securities or
         in certain markets.

     (2) The  associated  person  is not  compensated  in  connection  with  his
         participation  in the  offering by the payment of  commission  or other
         remuneration   based   directly  or  indirectly  on   transactions   in
         securities.

     (3) The  associated  person  is not at the  time  of his  participation  an
         associated person of a broker or dealer.

     (4) The associated person meets the conditions of any of (i), (ii) or (iii)
         below:

         (i)   The associated person restricts his participation to transactions
               involving   offers  and  sale  of  securities   under   specified
               circumstances  (none  of  which  are  expected  to  apply to this
               offering).

         (ii)  The associated person meets all of the following conditions:

                                       16

         transactions in securities;

               (B) The  associated  person  was not a broker  or  dealer,  or an

         offering  of  securities  for any issuer more than once every 12 months

         communication  through  the mails or other  means that does not involve
         oral  solicitation by the associated  person of a potential  purchaser;

         by a partner, officer or director of the issuer;

               (B)  Responding  to  inquiries  of  a  potential  purchaser  in a
         communication initiated by the potential purchaser;  Provided, however,

         effecting any transaction.

         With respect to the  requirements  of Rule 3a4-1,  consistent  with the

                        DESCRIPTION OF OFFERED SECURITIES

         Our Common Shares
         -----------------

         Our  articles of  continuance  authorize  the  issuance of an unlimited
number of common shares,  which do not have par value.  As of December 31, 2002,
there  were   30,244,348   common  shares  issued  and   outstanding,   held  by
approximately 500 registered  holders.  Holders of common shares are entitled to
one vote per share on all  matters to be voted on by  shareholders.  There is no
cumulative  voting with  respect to the  election of  directors.  The holders of
common shares are entitled to receive dividends, if any, as may be declared from
time to time by our board of  directors  in its  discretion  from funds  legally
available therefor. Upon our liquidation, dissolution or winding up, the holders
of common  shares are  entitled  to receive  ratably  any assets  available  for
distribution  to  shareholders.  The common  shares have no  preemptive or other
subscription rights, and there are no conversion rights or redemption or sinking
fund  provisions  with respect to such  shares.  All of the  outstanding  common
shares are fully paid and nonassessable.

         As of  December  31,  2002,  we had issued and  outstanding  options to
acquire  4,061,700  common shares  issued  pursuant to its options plans and had
issued and outstanding  warrants to purchase  9,170,171  common shares issued in
various series.

         Neither our articles nor our bylaws  contain any  provision  that would
delay,  defer or  prevent a change in  control.  We have,  however,  adopted  an
Amended and Restated  Shareholder  Rights Plan Agreement dated October 15, 1999,
which allows our  shareholders  to acquire  additional  common shares at a price
that would create a strong  disincentive  to a tender offer or similar change of
control  transaction,  if a person acquires,  or announces an intent to acquire,
15% or more of the outstanding  common shares,  and if certain other  conditions
are met. A copy of this  agreement  is attached  as Exhibit  10.1 to our Current
Report on Form 8-K  filed  with the SEC on  November  18,  1999.  A copy of this
agreement is also  available  upon written  request to us. You should review the
entire agreement before making any investment decision.

         Series 2003A Warrants
         ---------------------

         Each Series 2003A Warrant  entitles the holder  thereof to purchase one
common share at any time prior to the fifth anniversary of the issue date at the
price equal to the greater of (i) $1.00 per share,  and (ii) 125% of the average
of the closing price of the common shares,  as reported on our principal trading


                                       18


market, during the calendar week preceding the calendar week in which we receive
and accept subscription proceeds for the particular investment.  The holder of a
Series 2003A  Warrant may exercise  such Warrant by delivering to the Company at
its principal office the Series 2003A Warrant certificate, the Subscription Form
attached thereto, and cash or certified check in an amount equal to the exercise
price  multiplied by the number of Series 2003A  Warrants being  exercised.  The
Series 2003A Warrants may only be exercised in increments equal to the lesser of
(a) 25,000  common  shares  and (b) the  number of shares  subject to the Series
2003A Warrant.  Each Series 2003A Warrant is freely  assignable,  subject to the
restrictions of applicable federal,  Canadian,  state, and provincial securities
laws.  The Series 2003A  Warrants  provide for the  adjustment  of the number of
common  shares  subject  thereto and the exercise  price in the event of a stock
split, stock dividend, merger, consolidation, or similar event.

         Canadian Transfer Restrictions
         ------------------------------

         Neither the common shares nor the 2003A  Warrants  offered  pursuant to
this prospectus may be knowingly resold or otherwise transferred in Canada for a
period of six months after the date of issuance.  Investors  will be required to
sign a subscription  agreement  pursuant to which they will agree to comply with
this restriction.

_______ Series 2003A Warrants                 Warrant Certificate No. 2003A-___

                  Void after 5:00 p.m., Mountain Standard Time
                           on _________________, 2007


                          ALTAIR NANOTECHNOLOGIES INC.
                     (Incorporated under the laws of Canada)

This Series 2003A  Warrant  Certificate  ("Warrant  Certificate")  is to certify
that, for value received,  ________________or  registered assigns (the "Holder")
shall have the right to purchase from Altair  Nanotechnologies Inc. (hereinafter
called the "Corporation") one fully paid and non-assessable  Common Share of the
Corporation (a "Common  Share") for each Series 2003A Warrant  (individually,  a
"Warrant")  represented  by this  Warrant  Certificate  during  the time  period
commencing  on the date this  Warrant is executed by the Company and  continuing
until 5:00 p.m.  (Mountain  Standard time) on  _______________  [five-years from
issue date] (the "Expiry Time"). As specified in the Corporation's  Registration
Statement  on Form  S-2,  File No.  333-102592,  covering  the  issuance  of the
Warrants,  the exercise  price for the purchase of each such Common Share is the
greater of (i) $1.00 per  share,  and (ii) 125% of the  average  of the  closing
price of the Common Shares,  as reported on the Nasdaq SmallCap  Market,  during
the calendar week preceding the calendar week in which the Corporation  received
and accepted subscription  proceeds for the Warrants.  During such week, 125% of
the average of the closing price of the Common Shares, as reported on the Nasdaq
SmallCap Market, was $_____. Accordingly, the exercise price for the purchase of
each such Common Share shall be U.S.  $_____ per share (the  "Exercise  Price").
The number of Common Shares to be received upon the exercise of each Warrant and
the Exercise Price may be adjusted from time to time as hereinafter set forth.

The Warrants shall be subject to the following terms and conditions:

1.       For the purposes of this Warrant, the term "Common Shares" means common
         shares without  nominal or par value in the capital of the  Corporation
         as  constituted  on the date  hereof;  provided  that in the event of a
         change,   subdivision,    redivision,    reduction,    combination   or
         consolidation  thereof or any other  adjustment under clause 10 hereof,
         or successive  such  changes,  subdivisions,  redivisions,  reductions,
         combinations,  consolidations or other adjustments, then subject to the
         adjustments, if any, having been made in accordance with the provisions
         of this Warrant Certificate,  "Common Shares" shall thereafter mean the
         shares,  other securities or other property resulting from such change,
         subdivision,  redivision,  reduction,  combination or  consolidation or
         other adjustment.

2.       This  Warrant  Certificate  shall  be  signed  by  an  officer  of  the
         Corporation  holding office at the time of signing, or any successor or
         replacement person and notwithstanding any change in any of the persons



                                    Ex. I-1



         holding  said  offices  between  the  time of  actual  signing  and the
         delivery  of the  Warrant  Certificate  and  notwithstanding  that such
         officer signing may not have held office at the date of the delivery of
         the Warrant  Certificate,  the Warrant  Certificate  so signed shall be
         valid and binding upon the Corporation.

3.       All rights  under any of the  Warrants in respect of which the right of
         subscription  and purchase  therein  provided for shall not theretofore
         have been exercised  shall wholly cease and determine and such Warrants
         shall be wholly void and of no valid or binding effect after the Expiry
         Time.

4.       The right to purchase  Common Shares  pursuant to the Warrants may only
         be exercised by the Holder at or before the Expiry Time by:

         (a)      duly completing and executing a Subscription  Form in the form
                  attached hereto, in the manner therein indicated; and

         (b)      surrendering  this Warrant  Certificate and the duly completed
                  and  executed  Subscription  Form  to the  Corporation  at the
                  address  specified in clause 22 below together with payment of
                  the purchase price for the Common Shares subscribed for in the
                  form of cash or a certified  cheque payable to the Corporation
                  in an  amount  equal to the  then  applicable  Exercise  Price
                  multiplied by the number of Common Shares subscribed for.

5.       Upon receipt of the Subscription  Form, this Warrant  Certificate,  and
         payment as aforesaid,  the Corporation  shall cause to be issued to the
         Holder  the number of Common  Shares to be issued and the Holder  shall
         become a  shareholder  of the  Corporation  in respect  of such  Common
         Shares,  effective as of the date of receipt by the Corporation of such
         Subscription  Form,  Warrant  Certificate,  and  payment  and  shall be
         entitled to delivery of a certificate or  certificates  evidencing such
         shares. The Corporation shall cause such certificate or certificates to
         be mailed to the Holder at the address or  addresses  specified in such
         Subscription  Form within ten (10)  business  days of such  receipt and
         payment as herein provided or, if so instructed by the Holder, held for
         pick-up  by the Holder at the  principal  office of the  registrar  and
         transfer agent of the Common Shares, Equity Transfer Services Inc. (the
         "Transfer Agent").

6.       No fractional shares or stock  representing  fractional shares shall be
         issued upon the  exercise  of any  Warrant.  In lieu of any  fractional
         shares which would otherwise be issuable,  the Corporation shall either
         pay cash equal to the product of such  fraction  multiplied by the fair
         market value of one share of Common  Stock on the date of exercise,  as
         determined in good faith by the  Corporation's  Board of Directors,  or
         issue  the  next  largest   whole  number  of  Common   Shares  at  the
         Corporation's option.

7.       Neither the Warrants nor any Common  Shares  issuable  upon exercise of
         the  Warrants  may be offered  or sold into  Canada for a period of six
         months  after the  issue  date of the  Warrants.  If the  Warrants  are
         exercised  prior  to the  expiration  of  such  six-month  period,  the
         certificates  evidencing the Common Shares issuable upon their exercise
         shall bear the legend set forth below:

                  THESE  SECURITIES  HAVE NOT BEEN  QUALIFIED  UNDER CANADIAN OR
                  PROVINCIAL  SECURITIES LAWS AND MAY NOT BE RESOLD OR OTHERWISE
                  TRANSFERRED  IN CANADA  PRIOR TO [THE DATE SIX MONTH  FROM THE
                  ISSUE DATE OF THE WARRANTS].

                                    Ex. I-2



8.       The holding of a Warrant shall not  constitute the Holder a shareholder
         of the  Corporation nor entitle him to any right or interest in respect
         thereof except as herein expressly provided.

9.       The Corporation  covenants and agrees that until the Expiry Time, while
         any of the Warrants  shall be  outstanding,  it shall reserve and there
         shall remain unissued out of its authorized capital a sufficient number
         of Common Shares to satisfy the right of purchase herein  provided,  as
         such right of purchase  may be  adjusted  pursuant to clauses 10 and 11
         hereof.  All Common  Shares  which shall be issued upon the exercise of
         the right to purchase herein provided for, upon payment therefor of the
         amount  at  which  such  Common  Shares  may at the  time be  purchased
         pursuant to the  provisions  hereof,  shall be issued as fully paid and
         non-assessable  shares and the holders  thereof  shall not be liable to
         the Corporation or its creditors in respect thereof.

10.      (a)      If and whenever at any time after the date hereof and prior to
                  the Expiry Time the Corporation shall (i) subdivide,  redivide
                  or change its then  outstanding  Common  Shares into a greater
                  number of Common Shares,  (ii) reduce,  combine or consolidate
                  its then  outstanding  Common  Shares into a lesser  number of
                  Common  Shares or (iii)  issue  Common  Shares (or  securities
                  exchangeable  for or  convertible  into Common  Shares) to the
                  holders of all or  substantially  all of its then  outstanding
                  Common Shares by way of a stock dividend or other distribution
                  (any  of  such   events   herein   called  a   "Common   Share
                  Reorganization"),  then the  Exercise  Price shall be adjusted
                  effective  immediately  after the  effective  date of any such
                  event in (i) or (ii)  above or the  record  date at which  the
                  holders of Common Shares are determined for the purpose of any
                  such dividend or  distribution in (iii) above, as the case may
                  be,  by  multiplying  the  Exercise  Price in  effect  on such
                  effective  date or  record  date,  as the  case  may be,  by a
                  fraction, the numerator of which shall be the number of Common
                  Shares  outstanding  on such effective date or record date, as
                  the case may be,  before  giving  effect to such Common  Share
                  Reorganization  and the  denominator  of  which  shall  be the
                  number of Common Shares  outstanding  immediately after giving
                  effect to such Common Share Reorganization  including,  in the
                  case where  securities  exchangeable  for or convertible  into
                  Common  Shares are  distributed,  the number of Common  Shares
                  that would be  outstanding if such  securities  were exchanged
                  for or converted into Common Shares.

         (b)      If and whenever at any time after the date hereof and prior to
                  the Expiry Time, the Corporation shall distribute any class of
                  shares or rights,  options  or  warrants  or other  securities
                  (other  than  those   referred  to  in  clause  10(a)  above),
                  evidences  of   indebtedness   or  property   (excluding  cash
                  dividends  paid in the  ordinary  course) to holders of all or
                  substantially all of its then outstanding  Common Shares,  the
                  number of Common Shares to be issued by the Corporation  under
                  this  Warrant  shall,  at the time of exercise of the right of
                  subscription and purchase under this Warrant  Certificate,  be
                  appropriately  adjusted and the Holder shall receive,  in lieu
                  of the  number of the  Common  Shares in  respect of which the
                  right to  purchase  is then  being  exercised,  the  aggregate
                  number of Common  Shares or other  securities or property that
                  the Holder would have been  entitled to receive as a result of
                  such  event,  if, on the record date  thereof,  the Holder had
                  been the  registered  holder of the number of Common Shares to
                  which the Holder was theretofore entitled upon the exercise of
                  the rights of the Holder hereunder.

         (c)      If and whenever at any time after the date hereof and prior to
                  the  Expiry  Time  there is a  capital  reorganization  of the
                  Corporation  or a  reclassification  or  other  change  in the
                  Common Shares (other than a Common Share  Reorganization) or a
                  consolidation  or merger or  amalgamation  of the  Corporation
                  with or into any other corporation or other entity (other than
                  a consolidation,  merger or amalgamation which does not result
                  in any  reclassification of the outstanding Common Shares or a


                                    Ex. I-3


                  change of the  Common  Shares  into  other  securities),  or a
                  transfer  of all  or  substantially  all of the  Corporation's
                  assets to  another  corporation  or other  entity in which the
                  holders of Common Shares are entitled to receive shares, other
                  securities or other  property (any of such events being called
                  a  "Capital  Reorganization"),  the  Holder,  where he has not
                  exercised the right of  subscription  and purchase  under this
                  Warrant  Certificate  prior  to the  effective  date  of  such
                  Capital Reorganization, shall be entitled to receive and shall
                  accept,  upon the exercise of such right,  on such date or any
                  time thereafter,  for the same aggregate consideration in lieu
                  of the  number  of Common  shares to which he was  theretofore
                  entitled to subscribe for and purchase,  the aggregate  number
                  of shares or other  securities  or  property  which the Holder
                  would  have  been  entitled  to  receive  as a result  of such
                  Capital  Reorganization if, on the effective date thereof,  he
                  had been the registered  holder of the number of Common Shares
                  to which he was  theretofore  entitled  to  subscribe  for and
                  purchase.

         (d)      If and whenever at any time after the date hereof and prior to
                  the Expiry  Time,  any of the events set out in clause  10(a),
                  (b) or (c)  shall  occur  and the  occurrence  of  such  event
                  results in an adjustment of the Exercise Price pursuant to the
                  provisions of this clause 10, then the number of Common Shares
                  purchaseable  pursuant  to  this  Warrant  shall  be  adjusted
                  contemporaneously with the adjustment of the Exercise Price by
                  multiplying   the  number  of  Common  Shares  then  otherwise
                  purchaseable  on  the  exercise  thereof  by a  fraction,  the
                  numerator  of which  shall  be the  Exercise  Price in  effect
                  immediately  prior to the  adjustment  and the  denominator of
                  which  shall  be  the  Exercise  Price   resulting  from  such
                  adjustment.

         (e)      If the  Corporation  takes any  action  affecting  its  Common
                  Shares to which the foregoing provisions of this clause 10, in
                  the  opinion  of the board of  directors  of the  Corporation,
                  acting  in good  faith,  are not  strictly  applicable,  or if
                  strictly  applicable would not fairly adjust the rights of the
                  Holder  against  dilution  in  accordance  with the intent and
                  purposes  hereof,  or would  otherwise  materially  affect the
                  rights  of the  Holder  hereunder,  then the  Corporation  may
                  execute  and  deliver  to  the  Holder  an  amendment   hereto
                  providing  for  an  adjustment  in  the  application  of  such
                  provisions  so as to adjust such rights as  aforesaid  in such
                  manner  as the  board  of  directors  of the  Corporation  may
                  determine to be equitable in the circumstances, acting in good
                  faith.  The  failure  of the  taking of action by the board of
                  directors of the  Corporation to so provide for any adjustment
                  on or prior to the effective  date of any action or occurrence
                  giving rise to such state of facts will be conclusive evidence
                  that  the  board  of  directors  has  determined  that  it  is
                  equitable to make no adjustment in the circumstances.

11.      The  following  rules  and  procedures   shall  be  applicable  to  the
         adjustments made pursuant to clause 10:

         (a)      any Common  Shares  owned or held by or for the account of the
                  Corporation shall be deemed not be to outstanding except that,
                  for the  purposes of clause 10, any Common  Shares  owned by a
                  pension  plan or  profit  sharing  plan for  employees  of the
                  Corporation or any of its subsidiaries shall not be considered
                  to be owned or held by or for the account of the Corporation;

         (b)      no adjustment in the Exercise Price shall be required unless a
                  change of at least 1% of the  prevailing  Exercise Price would
                  result,  provided,  however, that any adjustment which, except
                  for the provisions of this clause 11(b),  would otherwise have
                  been required to be made,  shall be carried  forward and taken
                  into account in any subsequent adjustment;

                                    Ex. I-4


         (c)      the  adjustments  provided for in clause 10 are cumulative and
                  shall  apply  to  successive   subdivisions,   consolidations,
                  dividends,  distributions  and other  events  resulting in any
                  adjustment under the provisions of such clause;

         (d)      in the absence of a  resolution  of the board of  directors of
                  the  Corporation  fixing a record  date  for any  dividend  or
                  distribution  referred  to in  clause  10(a)(iii)  above,  the
                  Corporation  shall be deemed to have fixed as the record  date
                  therefor the date on which such  dividend or  distribution  is
                  effected;

         (e)      if the  Corporation  sets a record date to take any action and
                  thereafter  and before the taking of such action  abandons its
                  plan to take such action,  then no  adjustment to the Exercise
                  Price will be required by reason of the setting of such record
                  date;

         (f)      forthwith  after any  adjustment to the Exercise  Price or the
                  number of Common Shares purchaseable pursuant to the Warrants,
                  the  Corporation  shall provide to the Holder a certificate of
                  an officer of the  Corporation  certifying as to the amount of
                  such  adjustment  and, in reasonable  detail,  describing  the
                  event  requiring  and the manner of computing  or  determining
                  such adjustment; and

         (g)      any question that at any time or from time to time arises with
                  respect to the amount of any  adjustment to the Exercise Price
                  or  other   adjustment   pursuant   to   clause  10  shall  be
                  conclusively  determined  by a firm of  independent  chartered
                  accountants (who may be the Corporation's  auditors)  selected
                  by the  board of  directors  of the  Corporation  and shall be
                  binding upon the Corporation and the Holder.

12.      With 30 days after the effective date or record date, as applicable, of
         any event  referred to in clause 10, the  Corporation  shall notify the
         Holder of the particulars of such event and the estimated amount of any
         adjustment required as a result thereof.

13.      On the happening of each and every such event set out in clause 10, the
         applicable  provisions of this Warrant,  including the Exercise  Price,
         shall,  ipso  facto,  be  deemed  to be  amended  accordingly  and  the
         Corporation  shall take all necessary  action so as to comply with such
         provisions as so amended.

14.      The  Corporation  shall not be  required  to deliver  certificates  for
         Common Shares while the share  transfer  books of the  Corporation  are
         properly  closed,  having regard to the provisions of clauses 10 and 11
         hereof,  prior to any  meeting of  shareholders  or for the  payment of
         dividends or for any other purpose and in the event of the surrender of
         any Warrant in accordance with the provisions  hereof and the making of
         any  subscription  and payment for the Common Shares called for thereby
         during any such period delivery of  certificates  for Common Shares may
         be  postponed  for not more  than  five (5) days  after the date of the
         re-opening of said share transfer books.  Provided,  however,  that any
         such  postponement  of  delivery  of  certificates   shall  be  without
         prejudice  to the  right of the  Holder  so  surrendering  the same and
         making  payment  during such period to receive after the share transfer
         books shall have been re-opened such certificates for the Common Shares
         called for,  as the same may be adjusted  pursuant to clauses 10 and 11
         hereof as a result of the  completion  of the event in respect of which
         the transfer books were closed.

15.      Subject as  hereinafter  provided,  all or any of the rights  conferred
         upon the Holder by the terms  hereof may be  enforced  by the Holder by
         appropriate   legal   proceedings.   No  recourse  under  or  upon  any
         obligation, covenant or agreement contained herein shall be had against
         any  shareholder  or  officer of the  Corporation  either  directly  or
         through the  Corporation,  it being expressly  agreed and declared that


                                    Ex. I-5


         the obligations under the Warrants are solely corporate obligations and
         that no personal  liability  whatever shall attach to or be incurred by
         the  shareholders  or  officers  of the  Corporation  or any of them in
         respect  thereof,  any and all  rights and  claims  against  every such
         shareholder,  officer or director  being hereby  expressly  waived as a
         condition of and as a consideration for the issue of the Warrants.

16.      (a)      The  Warrants and the Common  Shares  issuable  upon  exercise
                  thereof  may not be assigned  or  transferred  in Canada for a
                  period of six months after the issue date of the Warrant.  Any
                  purported transfer or assignment made other than in accordance
                  with  this  Section  16 shall be null and void and of no force
                  and effect.

         (b)      Any assignment  permitted hereunder shall be made by surrender
                  of  this  Warrant   Certificate  to  the  Corporation  at  its
                  principal  office with the Assignment Form annexed hereto duly
                  executed and funds sufficient to pay any transfer tax. In such
                  event,  the Corporation  shall,  without  charge,  execute and
                  deliver a new Warrant  Certificate in the name of the assignee
                  named in such Assignment Form, and the Warrants represented by
                  this Warrant  Certificate  shall  promptly be cancelled.  This
                  Warrant  Certificate  may be  divided or  combined  with other
                  Warrants which carry the same rights upon presentation thereof
                  at the  principal  office of the  Corporation  together with a
                  written  notice signed by the Holder  thereof,  specifying the
                  names  and  denominations  in  which  new  Warrants  are to be
                  issued.  The terms  "Warrant"  and  "Warrants"  as used herein
                  include any Warrants in  substitution  for or  replacement  of
                  this Warrant,  or into which the Warrant  represented  by this
                  Warrant Certificate may be divided or exchanged.

17.      The Holder may  subscribe  for and purchase any lesser number of Common
         Shares than the number of shares expressed in this Warrant  Certificate
         subject to a minimum  purchaser per exercise equal to the lesser of (a)
         25,000 Common Shares,  or (b) the total number of Common Shares subject
         to the  Warrant  Certificate.  In the  case of any  subscription  for a
         lesser number of Common Shares than  expressed in this or any successor
         Warrant  Certificate  or a transfer of any of the Warrants  pursuant to
         clause 16, the Holder  shall be  entitled  to receive at no cost to the
         Holder a new Warrant  Certificate in respect of the balance of Warrants
         not then exercised or transferred. Any new Warrant Certificate(s) shall
         be  mailed to the  Holder or  assignee  by the  Corporation  or, at its
         direction, the Transfer Agent, within five (5) business days of receipt
         by the  Corporation  of all  materials  required by clauses 5 or 16, as
         applicable.

18.      Each Holder of this Warrant,  the Warrant  Shares or any other security
         issued or issuable upon  exercise of this Warrant  shall  indemnify and
         hold harmless the  Corporation,  its  directors and officers,  and each
         person,  if any,  who  controls  the  Corporation,  against any losses,
         claims,  damages  or  liabilities,  joint  or  several,  to  which  the
         Corporation or any such director, officer or any such person may become
         subject  under any  applicable  law,  insofar as such  losses,  claims,
         damages or liabilities,  or actions in respect thereof, arise out of or
         are based upon the  disposition  by such Holder of the  Warrants or the
         Common  Shares  issuable upon the exercise of the Warrants in violation
         of the terms of this Warrant Certificate.

19.      If  any  Warrant  Certificate  becomes  stolen,   lost,   mutilated  or
         destroyed,  the  Corporation  shall,  on  such  terms  as it may in its
         discretion  acting  reasonably  impose,  issue  and sign a new  Warrant
         Certificate  of  like  denomination,  tenor  and  date  as the  Warrant
         Certificate so stolen, lost, mutilated or destroyed for delivery to the
         Holder.

                                    Ex. I-6


20.      The  Corporation  and  the  Transfer  Agent  may  deem  and  treat  the
         registered  holder of any Warrant  Certificate as the absolute owner of
         the Warrants represented thereby for all purposes,  and the Corporation
         and neither the Corporation nor the Transfer Agent shall be affected by
         any notice or knowledge to the contrary except where the Corporation or
         the Transfer Agent is required to take notice by statute or by order of
         a court of  competent  jurisdiction.  A Holder shall be entitled to the
         rights evidenced by such Warrant  Certificate free from all equities or
         rights of set-off  or  counterclaim  between  the  Corporation  and the
         original  or any  intermediate  holder  thereof and all persons may act
         accordingly  and the  receipt by any such  Holder of the Common  Shares
         purchaseable  pursuant to such Warrant shall be a good discharge to the
         Corporation  and the  Transfer  Agent  for the  same  and  neither  the
         Corporation  nor the Transfer  Agent shall be bound to inquire into the
         title of any such Holder except where the  Corporation  or the Transfer
         Agent is  required  to take notice by statute or by order of a court of
         competent jurisdiction.

21.      Provisions  of  this  Warrant   Certificate  may  be  amended  and  the
         observance  thereof may be waived (either  generally or in a particular
         instance  and either  retroactively  or  prospectively),  only with the
         written  consent  of  the  Company  and  the  Holder  of  this  Warrant
         Certificate.

22.      All notices to be sent hereunder shall be deemed to be validly given to
         the  Holders  of the  Warrants  on the date of  receipt  if  personally
         delivered, sent by telecopier or overnight courier, charges prepaid, or
         five days after  deposit in the United  States mail,  by  registered or
         certified  mail,  postage  prepaid,  addressed to such holders at their
         post office  addresses  appearing  in the  register of Warrant  holders
         caused to be  maintained  by the  Corporation.  All  notices to be sent
         hereunder shall be deemed to be validly given to the Corporation on the
         date  of  receipt  if  personally  delivered,  sent  by  telecopier  or
         overnight courier,  charges prepaid,  or five days after deposit in the
         United States mail, by registered or certified mail,  postage  prepaid,
         addressed to the Corporation at 1725 Sheridan Avenue,  Suite 140, Cody,
         Wyoming  82414 or such  other  address  as the  Corporation  shall have
         designated by written notice to such registered owner.

23.      This  Warrant  shall be governed by the laws of the State of Nevada and
         the  federal  laws of the United  States  applicable  therein  (without
         reference to the conflict of laws provisions thereof).


         IN WITNESS WHEREOF the Corporation has caused this Warrant  Certificate
to be signed by its duly authorized officer.

Item 15. Indemnification of Directors and Officers
--------------------------------------------------

Our Bylaws
----------

         The  Registrant's  Bylaws provide that, to the maximum extent permitted
by law, the Registrant  shall indemnify a director or officer of the Registrant,
a former director or officer of the Registrant,  or another  individual who acts
or acted at the Registrant's  request as a director or officer, or an individual
acting in a similar capacity, of another entity,  against all costs, charges and
expenses,  including  any amount paid to settle an action or satisfy a judgment,
reasonably  incurred  by the  individual  in  respect  of any  civil,  criminal,
administrative,  investigative  or other  proceeding in which the  individual is
involved because of that association with the Registrant or other entity.

The Canada Business Corporations Act
------------------------------------

         Section 124 of the Canada Business Corporations Act provides as follows
with respect to the indemnification of directors and officers:

         (1)  A  corporation   may  indemnify  a  director  or  officer  of  the
corporation,  a  former  director  or  officer  of the  corporation  or  another
individual  who acts or acted at the  corporation's  request  as a  director  or
officer,  or an  individual  acting in a similar  capacity,  of another  entity,
against all costs,  charges and expenses,  including an amount paid to settle an
action or satisfy a judgment,  reasonably  incurred by the individual in respect
of any civil,  criminal,  administrative,  investigative  or other proceeding in
which  the  individual  is  involved   because  of  that  association  with  the
corporation or other entity.

         (2) A corporation  may advance  moneys to a director,  officer or other
individual  for the costs,  charges and expenses of a proceeding  referred to in
subsection (1). The individual shall repay the moneys if the individual does not
fulfill the conditions of subsection (3).

                                     II-1


         (3) A corporation may not indemnify an individual  under subsection (1)
unless the individual

                  (a) acted  honestly  and in good faith with a view to the best
         interests  of the  corporation,  or,  as the case  may be,  to the best
         interests  of the  other  entity  for  which  the  individual  acted as
         director  or  officer  or in a similar  capacity  at the  corporation's
         request; and

                  (b) in the case of a  criminal  or  administrative  action  or
         proceeding that is enforced by a monetary  penalty,  the individual had
         reasonable  grounds for  believing  that the  individual's  conduct was
         lawful.

         (4) A  corporation  may with the  approval  of a  court,  indemnify  an
individual  referred to in subsection  (1), or advance  moneys under  subsection
(2), in respect of an action by or on behalf of the  corporation or other entity
to procure a  judgment  in its favor,  to which the  individual  is made a party
because of the individual's  association with the corporation or other entity as
described in subsection (1) against all costs,  charges and expenses  reasonably
incurred by the  individual in connection  with such action,  if the  individual
fulfills the conditions set out in subsection (3).

         (5)  Despite  subsection  (1),  an  individual   referred  to  in  that
subsection  is  entitled to  indemnity  from the  corporation  in respect of all
costs,  charges and expenses reasonably incurred by the individual in connection
with the defense of any civil, criminal, administrative,  investigative or other
proceeding  to which the  individual  is  subject  because  of the  individual's
association with the corporation or other entity as described in subsection (1),
if the individual seeking indemnity

                  (a) was not judged by the court or other  competent  authority
         to have  committed  any  fault  or  omitted  to do  anything  that  the
         individual ought to have done; and

                  (b) fulfills the conditions set out in subsection (3).

         (6) A corporation  may purchase and maintain  insurance for the benefit
of an individual referred to in subsection (1) against any liability incurred by
the individual

                  (a) in the  individual's  capacity as a director or officer of
         the corporation; or

                  (b) in the individual's  capacity as a director or officer, or
         similar capacity, of another entity, if the individual acts or acted in
         that capacity at the corporation's request.

         (7) A corporation, an individual or an entity referred to in subsection
(1) may apply to a court for an order  approving an indemnity under this section
and the court may so order and make any further order that it sees fit.

         (8) An applicant under subsection (7) shall give the Director notice of
the application and the Director is entitled to appear and be heard in person or
by counsel.

         (9) On an application  under  subsection (7) the court may order notice
to be given to any interested person and the person is entitled to appear and be
heard in person or by counsel.

Employment Agreements With Certain Officers
-------------------------------------------

         Pursuant to an  employment  agreement  with William P. Long,  the Chief
Executive Officer and a director of the Registrant, the Registrant has agreed to
assume all  liability  for and to indemnify,  protect,  save,  and hold Dr. Long
harmless from and against any and all losses, costs, expenses,  attorneys' fees,
claims, demands, liability, suits, and actions of every kind and character which
may be imposed upon or incurred by Dr. Long on account of,  arising  directly or
indirectly  from,  or in any  way  connected  with  or  related  to  Dr.  Long's
activities as an officer and member of the board of directors of the Registrant,
except as arise as a result of fraud,  felonious  conduct,  gross  negligence or


                                      II-2


acts of moral turpitude on the part of Dr. Long. In addition,  Mineral  Recovery
Systems, Inc. ("MRS"), a wholly-owned  subsidiary of the Registrant,  has agreed
to assume all liability for and to indemnify,  protect,  save, and hold harmless
Patrick Costin (Vice  President of the Registrant and President of MRS) from and
against any and all losses, costs, expenses,  attorneys' fees, claims,  demands,
liabilities,  suits and actions of every kind and character which may be imposed
on or incurred by Mr. Costin on account of, arising directly or indirectly from,
or in any way connected with Mr.  Costin's  activities as manager,  officer,  or
director of MRS or the Registrant.

Other Indemnification Information
---------------------------------

         Indemnification may be granted pursuant to any other agreement,  bylaw,
or  vote of  shareholders  or  directors.  In  addition  to the  foregoing,  the
Registrant  maintains  insurance  through a commercial  carrier  against certain
liabilities  which may be incurred by its directors and officers.  The foregoing
description is necessarily  general and does not describe all details  regarding
the  indemnification  of  officers,  directors  or  controlling  persons  of the
Registrant.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been  informed  that in the opinion of the SEC such  indemnification  is against
public  policy  as  expressed  in  the  Securities   Act,  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

         The rights of indemnification  described above are not exclusive of any
other rights of indemnification to which the persons indemnified may be entitled
under any bylaw, agreement, vote of stockholders or directors or otherwise.

Item 17. Undertakings.
----------------------

(a) The undersigned registrant hereby undertakes:

         (1) To file,  during any period in which offers or sales are being made
of  the  securities  registered  hereby,  a  post-effective  amendment  to  this
Registration Statement:

         (i) To include  any  prospectus  required  by section  10(a)(3)  of the
Securities Act;

         (ii) To reflect in the prospectus any facts or events arising after the
effective date of this registration statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental change in the information set forth in this Registration  Statement;
notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20% change in the maximum
aggregate  offering price set forth in the  "Calculation  of  Registration  Fee"
table in the effective registration statement;

         (iii) To include any material  information  with respect to the plan of
distribution  not  previously  disclosed in this  Registration  Statement or any
material change to such information in this Registration Statement;

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

                                      II-5


         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(b) Insofar as indemnification  for liabilities arising under the Securities Act
may be permitted to directors,  officers and controlling persons of the Company,
the   Company  has  been   informed   that  in  the  opinion  of  the  SEC  such
indemnification is against public policy as expressed in the Securities Act, and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against  such  liabilities  (other  than the  payment by the Company of expenses
incurred or paid by a director,  officer or controlling person of the Company in
the  successful  defense of any action,  suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered,  the Company  will,  unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.
