                                     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.

                                  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. We
have  not  generated  revenues  from the jig and have  scaled  back  development
efforts for the  foreseeable  future.  We have  generated only $141,576 of sales
revenues  in our  nanoparticle  business as of  September  30, 2002 and have not
completed  exploration  of the  Tennessee  mineral  property.  We can provide no
assurance  that we will ever  generate  revenues  from the jig or the  Tennessee
mineral property or that we will generate substantial revenues from the titanium
processing technology.

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 2000 were $6,647,367 and our losses
from  operations in 2001 were  $6,021,532.  We will continue to experience a net
operating loss until, and if, the titanium processing technology, the jig and/or
the Tennessee mineral property begin generating  significant  revenues.  Even if
any or all such products or projects begin generating  significant revenues, the
revenues may not exceed our costs of production and operating  expenses.  We may
not ever realize a profit from operations.

We may not be able to raise sufficient capital to meet future obligations.
--------------------------------------------------------------------------------
         As of September 30, 2002, we had $306,061 in cash and a working capital
deficit  of  $2,181,380.  Although  we  have  raised  additional  capital  since
September  30, 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 testing and development of the jig or 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.

                                       3


         We may not be able to 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 nanotechnology and/or minerals stocks;

        o   the economics of projects being pursued;

        o   industry  perception  of our ability to recover or produce  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 1, 2002, there were outstanding  warrants to purchase up
to 10,653,506  common shares at a weighted  average  exercise price of $1.79 per
share and  options  to  purchase  up to  3,911,700  common  shares at a weighted
average  exercise  price of $3.98 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 all such conversion  rights if all 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,  or (d) $0.10 per share.
Such prices 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) 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.

         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


                                       5


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.

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


                                       6


wholly-owned subsidiaries. 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.

We may issue  substantial  amounts  of  additional  shares  without  stockholder
approval.
--------------------------------------------------------------------------------
         Our  articles of  continuance  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 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 continued  listing  requirements  for such market by June 2,
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 2,  2003,  we expect to be  delisted  from the  Nasdaq
SmallCap  Market.   Delisting  from  the  Nasdaq  SmallCap  Market  may  have  a
significant  negative impact on the trading price,  volume and  marketability of
our common shares.

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.
--------------------------------------------------------------------------------
We are offering the offered shares and Series 2003A Warrants on a "best efforts"
basis.  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 receive  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 could  receive  some  revenues in various  stages of the testing and
evaluation  of the  pharmaceutical  application  of our  technology,  we may not
receive  significant  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


                                       8


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  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,  we 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  ceramic
oxide  nanoparticles.  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 nanoparticle  products for various  applications and
have no long-term  agreements with end users to purchase any of our 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 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 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, 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.

                                       9


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 2003 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
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.

                                       10


         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.

                                       11


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


                                       12


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. 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 March 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  September  30,  2002 was
$3,038,825 or approximately $0.12 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 Warrant are exercised at an assumed  exercise price
of $1.00 per share, our net tangible book value would be $4,388,825 or $0.15 per
common share at September  30, 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  $0.45 per
common share to purchasers.

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



                                                                              Per Unit       Per Offering

                                                                                       
Offering price (1).........................................................   $0.40          $600,000
Net tangible book value (deficit) at September 30, 2002....................   $0.12          $3,038,825
Increase attributable to purchase by new investors(2)......................   $0.03          $1,350,000
Pro forma net tangible book value (deficit) after the offering (2).........   $0.15          $4,388,825
Pro forma net tangible book value dilution to new investors (3)............   $0.45          $1,003,000


(1)      Reflects the sale of 1,500,000  common shares and 750,0000  Series 2003
         Warrants at an estimated  purchase  price per units of one common share
         and one-half  Series 2003 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 September
         30,  2002 was  26,203,902  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.

                        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
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.  Each
Series  2003A  Warrant  is freely  assignable,  subject to the  restrictions  of


                                       15


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 resold or otherwise transferred in Canada for a specified
period after issuance.


                                  LEGAL MATTERS

         The  validity of the shares being  offered  hereby is being passed upon
for us by Goodman and Carr LLP, Ontario, Canada.

                                     EXPERTS

         The consolidated  financial statements  incorporated in this prospectus
by reference  from the  Company's  Annual Report on Form 10-K for the year ended
December  31,  2001 have been  audited  by  Deloitte & Touche  LLP,  independent
auditors,  as stated in their report  (which  report  expresses  an  unqualified
opinion and includes an explanatory  paragraph referring to the uncertainty that
the Company will be able to continue as a going concern),  which is incorporated
herein by reference,  and have been so  incorporated in reliance upon the report
of such firm given upon their authority as experts in accounting and auditing.

                          INFORMATION ABOUT OUR COMPANY

         This  prospectus is  accompanied by copies of our Annual Report on Form
10-K for the year ended December 31, 2001 and our Quarterly  Report on Form 10-Q
for the quarter ended September 30, 2002.  These documents  contain  information
about us as of their  respective  dates. We recommend that you carefully  review
these documents as part of your review of this prospectus.

                               RECENT DEVELOPMENTS

         Effective  November 21, 2002, the principal  amount of the secured term
note that we issued to Doral 18, LLC was reduced from  $2,000,000  to $1,400,000
in  exchange  for our  issuance of  1,500,000  common  shares to Doral,  and the
maturity  date of the note was  extended  from March 31, 2003 to March 31, 2004.
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.

                                       16


         Effective  July 2, 2002, we changed our name from Altair  International
Inc. to Altair Nanotechnologies Inc. and moved our jurisdiction of incorporation
from the Ontario Business  Corporations Act to the Canada Business  Corporations
Act.  The purpose of the name change was to reflect our strategy of focusing our
business  on the supply of  nanomaterials  and to reflect  our  position  in the
nanotechnology  sector.  We changed  jurisdiction of  incorporation  because our
business  is  increasingly  being  conducted  on  an  international  basis,  and
operating  as a  Canadian  federal  company  will be more  consistent  with  our
international  focus.  Moreover,  a minimum of 25% of the directors of a company
incorporated  under  the  Canada  Business  Corporations  Act  must be  resident
Canadians  whereas  50% of the  directors  of a company  incorporated  under the
Ontario Business  Corporations Act must be resident Canadians.  Thus, the Canada
Business  Corporations Act's residency  requirements will increase the number of
qualified nominees for the board from which the Company may draw.

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


                                       II-1


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).

         (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 of the benefit of
an individual  referred to in subsection  (1) against any liability  incurred by
the individual

                                      II-2


                  (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
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,


                                      II-3


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.

         (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.

                                      II-5


         (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.
