The Resolution in relation to the Revision of the 2015 Annual Cap of Revenue Transactions contemplated under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services

(1)

Background

On 5 November 2001, the Company and Chinalco entered into the General Agreement on Mutual Provision of Production Supplies and Ancillary Services, pursuant to which Chinalco and the Company mutually provided production supplies and ancillary services to each other.

Such profit margin is considered reasonable as determined with reference to the current market practice in relevant industries. The comparable local market prices refer to the reference made to the prices charged or quoted by at least two independent third parties providing products with comparable scale in areas where such products were provided under normal trading conditions.

(b)

Supporting services and ancillary production services:

(i)

Electricity supply: the price is determined with reference to the government-prescribed price, which refers to the ongrid electricity prices and electricity sales prices proposed to be executed by enterprises set out in the notices issued by the bureau of commodity price in each province published on their websites from time to time;

- 5 -

LETTER FROM THE BOARD

(ii)

Gas, heat and water supply, measurement, spare parts, repair, testing, transportation, steam: the price is determined with reference to the contractual price, which refers to a mutually agreed price set by all relevant parties for the provision of services. Such price is equivalent to reasonable costs incurred in providing such services plus reasonable profit. Such reasonable profit refers to a profit not more than 5% of such costs. Such profit margin is considered reasonable as determined with reference to the current market practice in relevant industries;

(iii)

Other services: the price is determined with reference to the comparable local market prices, which refer to the reference made to the prices charged or quoted by at least two independent third parties providing services with comparable scale in areas where such services were provided under normal trading conditions.

Separate operative agreements will be entered into under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services by the relevant parties from time to time, and the price of the products or services provided or received by parties will be negotiated and determined on a case by case basis in accordance with the pricing policies as set out above.

Payment method:

Payment on delivery (payment shall generally be made (a) within a period of time after the delivery of the relevant products at the place designated by the purchasing party or the provision of the relevant services, and the completion of necessary inspections and internal approval procedures; or (b) after setting-off the amounts due between the parties where there is mutual provision of products and services.

LETTER FROM THE BOARD

Historical Transaction Amount and Proposed Revised Annual Cap

For the two years ended 31 December 2014 and the ten months ended 31 October 2015, the historical transaction amounts of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services between the Company and Chinalco were approximately RMB6.98 billion, RMB7.02 billion and RMB7.2 billion, respectively.

The Board has confirmed that as at the Latest Practicable Date, the transaction amount of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services for the year 2015 has not exceeded RMB8 billion, being the existing annual cap for the year 2015. The Board further undertakes that the transaction amount of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services for the year 2015 will not exceed the existing annual cap for the year 2015 before the Independent Shareholders' approval on the revised annual cap at the EGM.

After taking the following factors into consideration, the Company and Chinalco intend to revise the 2015 annual cap regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services to RMB10 billion in the Supplemental Agreement:

(i)

the Company sold 6 aluminum processing enterprises to Chinalco in June 2013 and continued to provide electrolytic aluminium products to such enterprises, which resulted in a significant increase in the sales amount of products and services regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services between the Company and Chinalco compared with the estimated transaction amount when setting up the existing annual cap in 2012;

(ii)

a significantly increasing demand of Chinalco arising from its daily operation to procure copper products and other metal parts from the Group is emerging because Chinalco strengthened its management of centralized purchasing in the second half of the year 2015; and

- 7 -

LETTER FROM THE BOARD

(iii)

as originally scheduled, Chinalco and its subsidiaries plan to reserve aluminum products at the end of this year which should be sufficient for their daily production and operation at the beginning of next year, considering that the aluminium price is relatively lower in the current market and also aiming to avoid the inconvenience in freight transport resulting from the Spring Festival travel peak at the early beginning of next year. Because the existing annual cap regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services is expected to be exceeded, a large number of orders (total amount of such orders will be approximately RMB2 billion) from Chinalco and its subsidiaries to purchase aluminum products, copper products, spare parts and other products from the Company, mainly used as reserves and for their use in production and operation next year, is pending for signing subject to the Independent Shareholders' approval on the revised annual cap at the EGM.

Based on the above, the Directors (including the independent non-executive Directors) are of the view that the revision of the annual cap for the year 2015 regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services is fair and reasonable, and is in the interests of the Company and its Shareholders as a whole.

Save as disclosed above, all the existing principal terms and conditions of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services remain unchanged.

2.

The Resolution in relation to the Entering into the New Finance Lease Framework Agreement and the Proposed Cap thereunder

(1)

Background

On 27 August 2015, the Company and Chinalco Lease entered into the Original Finance Lease Framework Agreement, pursuant to which Chinalco Lease provided finance lease services to the Group with an effective term from 27 August 2015 to 31 December 2016. According to the Original Finance Lease Framework Agreement, at any time within the effective term of the agreement, the financing balance acquired by the Group from Chinalco Lease shall not exceed RMB1.5 billion. On 8 September 2015, both parties adjusted the proposed cap under the Original Finance Lease Framework Agreement to not more than RMB1.4 billion.

LETTER FROM THE BOARD

The New Finance Lease Framework Agreement

On 13 November 2015, the Company and Chinalco Lease entered into the New Finance Lease Framework Agreement, pursuant to which the agreed term, the methods of finance lease and the financing amount and etc. under the Original Finance Lease Framework Agreement were revised by both parties. The principal terms of the New Finance Lease Framework Agreement are set out below:

Parties

(1)

the Company (as the lessee, for itself and on behalf of its subsidiaries); and

(2)

Chinalco Lease (as the lessor, for itself and on behalf of its subsidiaries)

Term

Three years from 1 January 2016 to 31 December 2018

Methods and Arrangements of Finance Lease

The Group proposed to obtain the financing by way of sale-and-leaseback arrangements or direct leasing arrangements: (1) under the sale-and-leaseback arrangements, the Group will sell its own assets to Chinalco Lease to obtain financing, and then the Group will lease back the sold assets from Chinalco Lease and pay rental to Chinalco Lease. Upon expiry of the lease term, the Group will repurchase the assets from Chinalco Lease after the rental has been fully paid to Chinalco Lease in accordance with corresponding operative agreements; (2) under the direct leasing arrangements, Chinalco Lease will directly purchase the new equipment as required by the Group and lease the same to the Group for its use. The Group will pay rental to Chinalco Lease accordingly. Upon expiry of the lease term, the Group will purchase the assets from Chinalco Lease at a specific price after the rental has been fully paid to Chinalco Lease in accordance with corresponding operative agreements. The scope of the assets under the finance lease includes production equipment in relation to alumina, electrolytic aluminum, mining and energy power etc., and the carrying amount of such assets shall be not less than the principal amount under the finance lease in any event.

- 9 -

LETTER FROM THE BOARD

Financing Amount

At any time within the effective term of the New Finance Lease Framework Agreement, the financing balance acquired by the Group from Chinalco Lease shall not exceed RMB10 billion. The financing balance represents the aggregate principal amount outstanding in the finance lease period plus any lease interest, commission fees and other expenses, if applicable, incurred since the beginning of the then year to that exact point of time under the New Finance Lease Framework Agreement.

Financing Cost

The financing cost mainly includes lease interest and commission fees, etc. The costs of finance lease services provided by Chinalco Lease shall not be higher than the financing costs of services of similar nature provided by third party finance lease companies in the PRC (the after-tax internal rate of return shall prevail). The lease interest shall be determined with reference to the benchmark interest rate for RMB-denominated loans published by PBOC on a regular basis; if such rate is not available, then the lease interest shall be determined with reference to the interest rate obtained or quoted by other major finance institutions when providing same services or services of similar kind.

Legal Title of the Leased Assets and Repurchase

During the term of the finance lease operated under the New Finance Lease Framework Agreement, the legal title of the leased assets shall vest in Chinalco Lease. Upon expiry of such term, the Group will repurchase all the leased assets together with the corresponding legal title from Chinalco Lease at a nominal price of not more than RMB1.

Effectiveness of the Agreement

The New Finance Lease Framework Agreement shall be subject to the approval of the Independent Shareholders at the EGM.

Under the premise of compliance with the New Finance Lease Framework Agreement, the Group and Chinalco Lease shall further enter into separate operative contracts or agreements in respect of providing the specific finance lease service and determine the specific terms of the transaction. Such separate operative contracts or agreements shall be in accordance with the principles and terms of the agreement as well as requirements of the applicable laws.

LETTER FROM THE BOARD

(3)

Proposed Cap under the New Finance Lease Framework Agreement and the Basis for Determining the Proposed Cap

Taking into account the Group's future business development plans and its needs for the finance lease services provided by Chinalco Lease arising from the Group's daily operation and development, considering that there are some difficulties of the electrolytic aluminum enterprises, coal enterprises and newly established enterprises of the Group in obtaining additional financing from commercial banks, the Company proposes to set the financing balance (i.e. the proposed cap) under the New Finance Lease Framework Agreement at RMB10 billion, which means that at any time within the effective term of the New Finance Lease Framework Agreement (from 1 January 2016 to 31 December 2018), the financing balance acquired by the Group from Chinalco Lease shall not exceed RMB10 billion. The financing balance represents the aggregate principal amount outstanding in the finance lease period plus any lease interest, commission fees and other expenses, if applicable, incurred since the beginning of the then year to that exact point of time under the New Finance Lease Framework Agreement.

The proposed cap was determined by the Company with reference to the following factors:

(i)

the Group's future business development plans and its demand for the finance lease services provided by Chinalco Lease arising from the Group's daily operation and development. Pursuant to the budget of capital expenditure of the Group, the Group expects to continuously increase its investment in the construction of mining, alumina and electrical energy projects;

(ii)

the current financing market conditions, the interest rate and the potential adjustments to be made by PBOC in the benchmark interest rate for RMB-denominated loans in the future. In the case of any adjustment to the benchmark interest rate for RMB-denominated loans made by the PBOC in the future, the lease interest specified in the newly-signed individual operative agreement will be determined with reference to the adjusted benchmark interest rate for RMB-denominated loans;

Note:

the existing benchmark interest rates for RMB-denominated loans published by the PBOC are as follows:

*

4.35% for loans with terms not more than six months;

*

4.35% for loans with terms over six months but not more than one year;

*

4.75% for loans with terms over one year but not more than three years;

*

4.75% for loans with terms over three years but not more than five years; and

*

4.9% for loans with terms over five years.

- 11 -

LETTER FROM THE BOARD

(iii)

the nature and the carrying value of the leased assets. The carrying amount of the leased assets shall be not less than the principal amount under the finance lease in any event; and

(iv)

provision of approximately 5% buffer for unexpected fluctuations in the growth of the financing balance during the term of the New Finance Lease Framework Agreement.

INTRODUCTION

We refer to our appointment as independent financial adviser to advise the Independent Board Committee and the Independent Shareholders in respect of the terms of (1) the revision of 2015 annual cap for the continuing connected (revenue) transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services (the "Revision of 2015 Annual Cap"); and (2) the continuing connected transactions under the New Finance Lease Framework Agreement and the proposed annual caps thereunder for each of the three years ending 31 December 2016, 2017 and 2018, particulars of which are set out in the circular (the "Circular") of the Company dated 14 December 2015 and in which this letter is reproduced.

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

As at the Latest Practicable Date,

1.

Chinalco is the controlling shareholder of the Company and, hence, Chinalco is the connected person of the Company under the Hong Kong Listing Rules; and

2.

Chinalco Lease is a subsidiary of Chinalco and, hence, Chinalco Lease is also a connected person of the Company under the Hong Kong Listing Rules.

Since one or more applicable percentage ratios (as defined in Rule 14A.06 under the Hong Kong Listing Rules) in respect of each of (1) the revised annual cap for the revenue transactions contemplated under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services and (2) the transaction contemplated under the New Finance Lease Framework Agreement exceed 5%, each of (1) the Revision of 2015 Annual Cap and (2) the transactions contemplated under the New Finance Lease Framework Agreement (including the proposed annual caps thereunder) is subject to the reporting, announcement and the Independent Shareholders' approval requirements.

As at the Latest Practicable Date, we did not have any relationships or interests with the Group or any other parties that could reasonably be regarded as relevant to the independence of us. Around the last two years up to the Latest Practicable Date, we acted as an independent financial adviser to the independent board committee and independent shareholders of:

1.

the Company in relation to its major disposal and connected transactions (details of which were set out in its circular dated 14 November 2013);

2.

China Aluminum International Engineering Corp. Ltd. (stock code: 2068 HK)(being the Company's sister company under common control by Chinalco) in relation to its non-exempt continuing connected transactions (details of which were set out in its circular dated 11 September 2014); and

3.

the Company in relation to renewal of its non-exempt continuing connected transactions (details of which were set out in its circular dated 2 June 2015).

Apart from normal professional fee paid to us in connection with the aforesaid and the captioned appointments, no arrangements exist whereby we had received any fees or benefits from the Company or any other party to the aforesaid and the captioned transactions, and therefore we consider such prior relationship would not affect our independence.

(1)

REVISION OF THE 2015 ANNUAL CAP REGARDING THE REVENUE TRANSACTIONS UNDER THE GENERAL AGREEMENT ON MUTUAL PROVISION OF PRODUCTION SUPPLIES AND ANCILLARY SERVICES

Principal factors considered

1.

Background of the General Agreement on Mutual Provision of Production Supplies and Ancillary Services

Information of Chinalco

Chinalco is primarily engaged in the business which includes the production and sales of aluminum, copper, rare earth and relevant non-ferrous metals and mineral products, smelted products, processed products and carbon products.

Information of the Company

The Company is principally engaged in the mining of bauxite, the production and sales of alumina and primary aluminum, the operation of coal and iron ore businesses as well as the trading of other non-ferrous metal products.

- 32 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Background for entering the General Agreement on Mutual Provision of Production Supplies and Ancillary Services

We have reviewed the prospectus of the Company dated 30 November 2001, noting that prior to the listing of the Shares on the Hong Kong Stock Exchange (the "IPO"), Chinalco was reorganised for the purpose of the IPO (the "Reorganisation"). As part of the Reorganisation, Chinalco transferred to the Group, amongst other things, (i) the operating assets and businesses in relation to the production of alumina, primary aluminum and scrap materials, coal and pitch; and (ii) the assets and businesses for provision of ancillary production supplies and services, including, but not limited to, supply of electricity, gas, heat, water and spare parts and provision of repair and measurement services. On the other hands, Chinalco retained certain non-core assets and businesses in relation to ancillary production supplies and services, which continue to provide the same supplies and services to the Group after the Reorganisation.

Prior to the IPO, the Company and Chinalco entered into the General Agreement on Mutual Provision of Production Supplies and Ancillary Services dated 5 November 2001 in order to regulate the ongoing mutual production supplies and ancillary services transactions to each other. After several rounds of subsequent extension, and on 24 August 2012, such agreement was renewed for yet another three years from 1 January 2013 to 31 December 2015.

2.

Reasons for the Revision of 2015 Annual Cap

As disclosed in the 2013 annual report of the Company, the Company entered into an equity interest transfer agreement on 9 June 2013, pursuant to which the Company transferred to Chinalco six aluminum processing subsidiaries, namely:

(1)

Chalco Henan Aluminum Co., Ltd. ();

(2)

Chalco Southwest Aluminum Co., Ltd. ();

(3)

Chalco Southwest Aluminum Cold Rolling Co., Ltd. ();

(4)

Huaxi Aluminum Co., Ltd. ();

(5)

Chalco Ruimin Co., Ltd. (); and

(6)

Chalco Qingdao Light Metal Co., Ltd. () (collectively known as the "Aluminum Fabrication Subsidiaries").

- 33 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

The aforesaid transactions were completed on 27 June 2013 (the "2013 Disposal"). Prior to the 2013 Disposal, the Aluminum Fabrication Subsidiaries (together with an aluminum fabrication branch) formed the Aluminum Fabrication segment of the Group, representing one of the six reportable operating segments (namely, (1) Aluminum Fabrication, (2) Alumina, (3) Primary Aluminum, (4) Energy, (5) Trading, (6) Corporate and other operating segments) of the Company. We understand from the Company that, prior to the 2013 Disposal, the Primary Aluminum segment supplied (on intra-group basis) primary aluminum (i.e. electrolytic aluminium) to the Aluminum Fabrication segment for further processing and fabricating into aluminum fabricated products in the normal course of the business of the Company. After the 2013 Disposal, the Aluminum Fabrication segment was no longer consolidated into the Company's financial results. As the aforesaid primary aluminum (i.e. electrolytic aluminium) supply transactions were to continue in spite of the 2013 Disposal, these previously intra-group transactions would after the 2013 Disposal be classified as continuing connected transactions pursuant to the Listing Rules (the "New Continuing Connected Transactions after the 2013 Disposal"), and would accordingly become regulated by the General Agreement on Mutual Provision of Production Supplies and Ancillary Services including the annual caps for the revenue transactions.

We further understand from the Company that when the General Agreement on Mutual Provision of Production Supplies and Ancillary Services was renewed in 2012, the basis for determining such relevant annual caps of the revenue transactions under the same Agreement for the three years ending 31 December 2015 did not take into account (and to be more precise, cannot have taken into account, due to timing difference) the impact from the New Continuing Connected Transactions after the 2013 Disposal. In this connection, we have reviewed the original circular dated 12 October 2012 under which the General Agreement on Mutual Provision of Production Supplies and Ancillary Services was extended and the annual caps for the three years ending 31 December 2015 were determined. According to that circular, the existing annual caps for the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services of each of the three financial years ending 31 December 2015 were RMB7,000 million, RMB7,500 million and RMB8,000 million respectively.

- 34 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

We understand from the Company that, mainly in view of the impact from the New Continuing Connected Transactions after the 2013 Disposal, the Company and Chinalco entered into the Supplemental Agreement on 13 November 2015 to revise the existing annual cap for the year ending 31 December 2015 regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services. Having considered the above, in particular the revenue-generating nature of the Primary Aluminum segment of the Group to sell primary aluminum (i.e. electrolytic aluminium) as the Group's core business line, we are of the view that these New Continuing Connected Transactions after the 2013 Disposal for which the Revision of 2015 Annual Cap is intended are conducted in the usual and ordinary course of business of the Company, and are in the interest of the Company and the Shareholders as a whole.

3.

Revision of 2015 Annual Cap

The Company proposed to revise the 2015 annual cap for the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services from RMB8,000 million to RMB10,000 million, representing an increase of RMB2,000 million.

In determining the revised 2015 annual cap, the Company had taken into consideration the following factors:

(i)

the Company sold six aluminum processing enterprises to Chinalco in June 2013 and continued to provide electrolytic aluminium products to such enterprises, which resulted in a significant increase in the sales amount of products and services regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services between the Company and Chinalco compared with the estimated transaction amount when setting up the existing annual cap in 2012;

(ii)

a significantly increasing demand of Chinalco arising from its daily operation to procure copper products and other metal parts from the Group is emerging because Chinalco strengthened its management of centralized purchasing in the second half of the year 2015; and

- 35 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

(iii)

as originally scheduled, Chinalco and its subsidiaries plan to reserve aluminum products at the end of this year which should be sufficient for their daily production and operation at the beginning of next year, considering that the aluminium price is relatively lower in the market currently and also aiming to avoid the inconvenience in freight transport resulting from the Spring Festival travel rush at the early beginning of next year. Because the original cap regarding the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services is expected to be exceeded, a large number of orders (total amount of such orders will be approximately RMB2 billion) from Chinalco and its subsidiaries to purchase aluminium products, copper products, spare parts and other products from the Company, mainly used as reserves and for their use in production and operation next year, is pending for signing subject to the Independent Shareholders' approval on the revised annual cap at the EGM.

In this connection, we have reviewed the orders (in writing) from Chinalco and notice that the products ordered include (i) primary aluminum products (sub-totalling at RMB1.2 billion), (ii) copper products (sub-totalling at RMB0.6 billion), and (iii) spare parts and coal products (sub-totalling at RMB0.2 billion), and such orders amount to RMB2 billion in total. We have also obtained written indication from Chinalco that operative agreements in respect of such orders can be signed by Chinalco as soon as the relevant approval is obtained (from the Independent Shareholders at the EGM).

Further, we summarise below the actual historical amounts and the estimated annual amount for each of (i) the continuing connected (revenue) transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services and (ii) the New Connected Transactions after the 2013 Disposal, as obtained during our due diligence enquiry with the Company:

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Notes:

1.

The basis for determining such existing annual cap did not include the impact from the New Continuing Connected Transactions after the 2013 Disposal.

2.

Already included the impact from the New Continuing Connected Transactions after the 2013 Disposal.

3.

Based on an annualised version of RMB8,640 million as derived from the actual historical amounts for the ten months ended 31 October 2015 (being RMB7,200 million x 12 months/10 months).

4.

The Board has confirmed that as at the Latest Practicable Date, the actual historical amount of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services for the year 2015 has not exceeded RMB8 billion, being the existing annual cap for the year 2015.

5.

The Board undertakes that the transaction amount of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services for the year 2015 will not exceed the existing annual cap for the year 2015 before the Independent Shareholders' approval on the revised annual cap at the EGM.

We notice from the above table that the New Continuing Connected Transactions after the 2013 Disposal are estimated at RMB2,000 million for the year ending 31 December 2015, which represents exactly the increase of the proposed revised 2015 annual cap over the existing 2015 annual cap.

To assess the fairness and reasonableness of the Company's estimation about the size for the New Continuing Connected Transactions after the 2013 Disposal (which in turn drives the Revision of 2015 Annual Cap), we have reviewed the A-share annual reports and H-share annual reports of the Company. As disclosed in the A-share annual report of the Company, the actual historical transactions between the Company and three out of a total of six relevant disposed companies, namely Huaxi Aluminum Co., Ltd. (), Chalco Ruimin Co., Ltd. () and (a subsidiary of Chalco Southwest Aluminum Cold Rolling Co., Ltd. ()), amounted to RMB1,582 million and RMB1,963 million in 2013 and 2014 respectively, which are identical to the amounts of the New Continuing Connected Transactions after the 2013 Disposal as set out in the above table.

- 37 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Upon our due diligence enquiry, we understand from the Company that such amounts of the New Continuing Connected Transactions after the 2013 Disposal of RMB1,582 million and RMB1,963 million in 2013 and 2014 did not contribute enough to result in each of the existing 2013 and 2014 annual caps being exceeded, given that the remaining portion of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services did not actually record a significantly enough increase during the relevant period. This was unlike what is otherwise expected for the year ending 31 December 2015, when the estimated amount of the New Continuing Connected Transactions after the 2013 Disposal of RMB2,000 million in 2015 is expected to contribute enough to result in the existing 2015 annual caps being exceeded, given that the remaining portion of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services (1) had actually recorded a significantly enough increase arising from Chinalco's daily operation to procure copper products and other metal parts from the Group is emerging because Chinalco strengthened its management of centralized purchasing in the second half of the year 2015; and (2) is expected to actually record a significantly enough increase arising from Chinalco's plan to reserve aluminum products at the end of this year.

Upon comparison, we note that the 2015 estimated annual amount for the New Connected Transactions after the 2013 Disposal of RMB2,000 million represents an increase of merely approximately 1% over the 2014 actual annual amount of RMB1,963 million. Upon further comparison, we have reviewed the H-share 2015 interim report of the Company and find that the primary aluminum sales of the Company (including sales to both independent customers and Chinalco) increased by approximately 5.7% in the first half of 2015 as compared to the same period in 2014. Hence, we are of the view that the approximately 1% estimated increase for the New Connected Transactions after the 2013 Disposal in 2015 over that in 2014 is prudently in line with the trend of the primary aluminum sales of the Company. On such basis, we are of the view that the estimation of the amount of the New Continuing Connected Transactions after the 2013 Disposal at RMB2,000 million is fair and reasonable.

Based on the impact from the New Continuing Connected Transactions after the 2013 Disposal (which is estimated at RMB2,000 million for the year ending 31 December 2015, out of which as to RMB1,500 million (or 75%) has actually been transacted up to 31 October 2015 already), and taking into further account that the annualised revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services (after including the New Continuing Connected Transactions after the 2013 Disposal) of RMB8,640 million as derived from the actual historical amounts for the ten months ended 31 October 2015 is expected to exceed the existing 2015 annual cap of RMB8,000 million, we are of the view that the Revision of 2015 Annual Cap to RMB10,000 million is fair and reasonable.

Principal terms of the New Continuing Connected Transactions after the 2013 Disposal

According to the section headed "Renewal of the Non-Exempt Continuing Connected Transactions" in the letter from the Board of the Circular dated 12 October 2012 and the Supplemental Circular dated 2 June 2015, the principal terms of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services are summarised in the following table:

Nature of
    Transaction

Supplies and ancillary services provided by the Company to Chinalco:

1)

Products: aluminum products (aluminum ingots) and alumina products, primary aluminum, slag, pitch and other relevant or similar supplies; and

2)

Supporting services and ancillary production services: water, electricity, gas and heat supply, measurement, spare parts, repair, testing, transportation, steam and other relevant or similar services.

Pricing basis

a)

Products:

1)

Alumina products: the selling price is determined according to a method where both the alumina spot market price and the weighted average price of settlement price for three-month aluminum ingot futures on the Shanghai Futures Exchange weighted in proportion. The Company will consider the geographical location of the customers, the seasonality demands, the transportation costs, and other relevant factors to determine the proportion of weight to be allocated to the aforementioned alumina spot market price and the weighted average price of settlement price for three-month aluminium ingot futures on the Shanghai Futures Exchange;

2)

Aluminum products (aluminium ingots): the trading price is determined according to the prices of futures in the current month, the weekly or monthly average spot market prices quoted on the Shanghai Futures Exchange;

- 39 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

3)

Other products: the price is determined with reference to the contractual price or the comparable local market prices. The contractual price refers to a mutually agreed price set by all relevant parties for the provision of products. Such price is equivalent to reasonable costs incurred in providing such products plus reasonable profit. Such reasonable profit refers to a profit not more than 5% of such costs. Such profit margin is considered reasonable as determined with reference to the current market practice in relevant industries. The comparable local market prices refer to the reference made to the prices charged or quoted by at least two independent third parties providing products with comparable scale in areas where such products were provided under normal trading conditions.

b)

Supporting services and ancillary production services:

1)

Electricity supply: the price is determined with reference to the government-prescribed price, which refers to the on-grid electricity prices and electricity sales prices proposed to be executed by enterprises set out in the notices issued by the bureau of commodity price in each province published on their websites from time to time;

2)

Gas, heat and water supply, measurement, spare parts, repair, testing, transportation, steam: the price is determined with reference to the contractual price, which refers to a mutually agreed price set by all relevant parties for the provision of services. Such price is equivalent to reasonable costs incurred in providing such services plus reasonable profit. Such reasonable profit refers to a profit not more than 5% of such costs. Such profit margin is considered reasonable as determined with reference to the current market practice in relevant industries;

- 40 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

3)

Other services: the price is determined with reference to the comparable local market prices, which refer to the reference made to the prices charged or quoted by at least two independent third parties providing services with comparable scale in areas where such services were provided under normal trading conditions.

Separate operative agreements will be entered into under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services by the relevant parties from time to time, and the price of the products or services provided or received by parties will be negotiated and determined on a case by case basis in accordance with the pricing policies as set out above.

Payment terms

Payment on delivery (payment shall generally be made):

1)

within a period of time after the delivery of the relevant products at the place designated by the purchasing party or the provision of the relevant service, and the completion of necessary inspections and internal approval procedures; or

2)

after setting-off the amounts due between the parties where there is mutual provision of products and services.

The relevant payment term shall be no less favorable than those under comparable transactions between the Company and independent third parties.

To assess the fairness and reasonableness of the principal terms of the New Continuing Connected Transactions after the 2013 Disposal, we have obtained and reviewed (1) sample contracts and invoices of the New Continuing Connected Transactions after the 2013 Disposal entered into between the Company and the Aluminum Fabrication Subsidiaries; and (2) sample comparable contracts and invoices entered into between the Company and independent third parties during the same period. Upon comparison, we are not aware of any reason to believe that the pricing basis and payment terms of the New Continuing Connected Transactions after the 2013 Disposal was not, in all material respects, in line with the corresponding terms stipulated in the General Agreement on Mutual Provision of Production Supplies and Ancillary Services.

- 41 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Having considered (1) the pricing basis and payment terms of the revenue transactions under the General Agreement on Mutual Provision of Production Supplies and Ancillary Services as summarised in the above table; (2) the relevant pricing basis and payment term of the New Continuing Connected Transactions after the 2013 Disposal is no less favorable than those offered by the independent third parties, we are of the view that the principal terms of the New Continuing Connected Transactions after the 2013 Disposal are on normal commercial terms and are fair and reasonable so far as the Independent Shareholders are concerned.

Recommendation

Having taken into account the above principal reasons and factors, we consider that the Revision of 2015 Annual Cap is fair and reasonable and is conducted in the ordinary and usual course of business of the Group and in the interests of the Company and the Shareholders as a whole.

Therefore, we advise the Independent Board Committee to recommend the Independent Shareholders to, and also recommend the Independent Shareholders to, vote in favor of the relevant resolution to approve the Revision of 2015 Annual Cap.

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Reasons for entering into the New Finance Lease Framework Agreement

We summarise the relevant event in chronological order in the table below:

Date

Event in chronological order

27 August 2015

*

the Company and Chinalco Lease entered into the Original Finance Lease Framework Agreement, pursuant to which, Chinalco Lease provided finance lease services to the Group with an effective term from 27 August 2015 to 31 December 2016.

*

According to the Original Finance Lease Framework Agreement, at any time within the effective term of the agreement, the financing balance acquired by the Group from Chinalco Lease shall not exceed RMB1.5 billion.

8 September 2015

*

both parties adjusted the proposed cap under the Original Finance Lease Framework Agreement to not more than RMB1.4 billion.

13 November 2015

*

the Company and Chinalco Lease entered into the New Finance Lease Framework Agreement, pursuant to which, the agreed term, the methods of finance lease and the financing amount under the Original Finance Lease Framework Agreement were revised by both parties.

Upon our due diligence discussion with management of the Company, we understand that some subsidiaries of the Company especially electrolytic aluminum companies, coal companies and newly established companies may have recently faced relatively greater difficulty in obtaining additional or renewal loans from commercial banks which have either quoted all-in financing cost rate levels which are higher than that of the finance lessors, or with overall terms that are less attractive. Thus, these subsidiaries of the Company have tried to sell and leaseback some of its existing assets or use direct leasing arrangements in order to finance their own operations. In this connection, we have cross-checked from the 2015 interim report and 2014 annual reports of the Company and note that the Group's balance of finance lease payable actually increased from zero at the end of 2013 to RMB4,621 million at the end of 30 June 2015 whereas, by contrast, the balance of bank and other loans decreased by approximately 17.2% from RMB82,449 million to RMB68,235 million in the corresponding period.

- 43 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

In other words, we understand that by entering into the New Finance Lease Framework Agreement, the Group is able to access to an alternative source of financing for its business operations from Chinalco Lease with competitive-cost funding under the current situation with tighter credit policies from commercial banks toward the electrolytic aluminum companies, coal companies and newly established companies, which could help lower the financing cost and facilitate the operation and the growth of the Group's business. We understand from the Company that Chinalco Lease, due to its under-common-control relationship with the Group and its deep knowledge and familiarity of the business of the Group, is able to design the repayment method based on the actual conditions of the Group in a flexible manner and provide timely and convenient financing funds, which allow the Company to optimise its financial management, improve its capital usage efficiency, decrease the financing cost and the financing risks, which is in favor of the business development and will smooth the progress of the operation of the Company. In addition, we notice from the annual reports and interim reports of the Company that the Group has the actual practice in the past years to have obtained funding through finance leasing with several independent third party lessors.

Having considered the above, we are of the view that the New Finance Lease Framework Agreement is in the usual and ordinary course of business of the Group, and is in the interests of the Company and the Shareholders as a whole.

2.

Principal terms of the New Finance Lease Framework Agreement

The Group proposed to obtain the financing by way of sale-and-leaseback arrangements or direct leasing arrangements:

(1)

under the sale-and-leaseback arrangements, the Group will sell its own assets to Chinalco Lease to obtain financing, and then the Group will lease back the sold assets from Chinalco Lease and pay rental to Chinalco Lease. Upon expiry of the lease term, the Group will repurchase the assets from Chinalco Lease after the rental has been fully paid to Chinalco Lease in accordance with corresponding operative agreements;

(2)

under the direct leasing arrangements, Chinalco Lease will directly purchase the new equipment as required by the Group and lease the same to the Group for its use. The Group will pay rental to Chinalco Lease accordingly. Upon expiry of the lease term, the Group will purchase the assets from Chinalco Lease at a specific price after the rental has been fully paid to Chinalco Lease in accordance with corresponding operative agreements.

- 44 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Under the premise of compliance with the New Finance Lease Framework Agreement, the Group and Chinalco Lease shall further enter into separate operative contracts or agreements in respect of providing the specific finance lease service and determine the specific terms of the transaction. Such separate operative contracts or agreements shall be in accordance with the principles and terms of the agreement as well as requirements of the applicable laws. Other key terms of the New Finance Lease Framework Agreement are set out in the "Letter from the Board" of the Circular.

To assess the reasonableness and fairness of the New Finance Lease Framework Agreement, we have obtained and reviewed most samples of the finance lease contracts entered into between the Group and other independent third party lessors since 2013 (the "Comparable Contracts"), being the earliest time the Group embarked on deploying financing service from lessors. The scope of the assets under the finance lease includes production equipment in relation to alumina, electrolytic aluminum, mining and energy power, etc.. We understand from management of the Company that the assets under the finance lease contract(s) contemplated under the New Finance Lease Framework Agreement are of similar nature with those under the Comparable Contracts. In addition, we note that the key terms of the New Finance Lease Framework Agreement and the Comparable Contracts are in close resemblance. In summary, according to the Comparable Contracts, we note that:

(i)

the "lease method" of both Comparable Contracts and the New Finance Lease Framework Agreement are both finance lease arrangements;

(ii)

the "title", being the legal ownership and all rights of the leased equipment, shall vest in the lessor throughout the lease period which is the same as that contemplated under the New Finance Lease Framework Agreement;

(iii)

the "financing cost" of the Comparable Contracts include (1) interest rate, (2) commission fees, and (3) deposit; whilst the "financing cost" of the New Finance Lease Framework Agreement mainly include (1) interest rate and (2) commission fees (with or without (3) deposit), which in aggregate shall not be higher than the financing cost of services of similar nature provided by third party finance lease companies in the PRC.

As far as (1) interest rate is concerned, we have enquired and understand from the Company that in practice, such interest rate shall be determined by reference to the benchmark lending rates for RMB-denominated loans as published by PBOC from time to time (or, if no such rate is available, by reference to, among others, the rate charged by the other major financial institutions in the PRC for the same or similar types of services), and shall reflect the credit risk assessment and the return requirements of the relevant finance lessor.

- 45 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

As far as (2) commission fees are concerned, we have enquired and understand from the Company that in practice, such commission fees are generally one-off and/or upfront in nature, which shall be determined by reference to, among others, the rate charged by the other major financial institutions in relation to finance leasing of the same or similar types of assets (or, if available, the applicable rates published by PBOC for these kinds of services from time to time), and shall reflect the credit risk assessment and the return requirements of the relevant finance lessor;

(iv)

the "purchase option", which is subject to the lessee having performed all its obligations under the lease period and upon the expiry of the lease period under the Comparable Contracts, carried a price of RMB1.0 to RMB100.0; whilst the New Finance Lease Framework Agreement provides that when the relevant finance lease contract is entered into, the Lessee shall have an option to purchase the relevant Leasing Equipment at a nominal price of not more than RMB1.0.

In addition, we understand from the Company that in assessing different financing options, the Company is focusing on comparing the after-tax internal rate of return (the "IRR") which takes into account a comprehensive set of factors including interest rate, commission fees, deposit, tax, any other expenses as well as the repayment method. We have obtained further confirmation from the Company that the finance leases offered by independent third party lessors would generally require a guarantee from the controlling shareholder and/or deposit ranging from 3% to 7% of the consideration, which would effectively increase the financing cost for the Company, whereas Chinalco Lease usually does not require such guarantee and deposit. Based on the terms of the New Finance Lease Framework Agreement and our understanding from the Company, the Company has internal procedures to compare and shortlist the quotation of the all-in financing cost (which is essentially the IRR) from both Chinalco Lease and independent third party lessors, and it is the exact terms of the New Finance Lease Framework Agreement that the all-in financing cost offered by Chinalco Lease will be no less favorable to the Company than that offered by independent third party lessors if Chinalco Lease is chosen by the Company to enter into separate written contract(s).

- 46 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

We have compared sample contracts of finance leases entered into between the Company and Chinalco Lease (under the Original Finance Lease Framework Agreement with an effective term commencing from 27 August 2015) and the Comparable Contracts and found that the terms offered by Chinalco Lease were no less favorable than those offered by the independent third financial institutions. Further, we understand that the Company has adopted a set of effective internal control policies to supervise the continuing connected transactions of the Company. Prior to entering into operative agreements, the authorised departments of the Group will review and assess the specific terms and conditions of the transactions to ensure their consistency with the New Finance Lease Framework Agreement and determine the lease interest and commission fees with reference to the current market conditions and the prices charged or quoted by at least two independent third parties providing services of similar nature with comparable scale under normal trading conditions around that time. The financial department of the Company traces, monitors and checks the progress of the continuing connected transactions of the Company on a monthly basis.

In consideration of above, we are of the view that the terms of the New Finance Lease Framework Agreement are on normal commercial terms and are fair and reasonable so far as the Independent Shareholders are concerned.

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Notes:

1.

The financing balance for the three years ending 31 December 2018 represents the aggregate principal amount outstanding in the finance lease period plus any lease interest, commission fees and other expenses, if applicable, incurred since the beginning of the then year to that exact point of time under the New Finance Lease Framework Agreement.

2.

The financing balance for the three years ending 31 December 2015 represents the aggregate principal amount outstanding.

As set out in the Letter from the Board, in arriving at the proposed annual caps for the transactions contemplated under the New Finance Lease Agreement, the Directors have considered, among other things, (i) the Group's future business development plans and its demand for the finance lease services provided by Chinalco Lease arising from the Group's daily operation and development. Pursuant to the budget of capital expenditure of the Group, the Group expects to continuously increase its investment in the construction of mining, alumina and electrical energy projects; (ii) the current financing market conditions, the interest rate and the potential adjustments to be made by the PBOC in the benchmark interest rate for RMB-denominated loans in the future. In the case of any adjustment to the benchmark interest rate for RMB-denominated loans made by the PBOC in the future, the lease interest specified in the newly-signed individual operative agreement will be determined with reference to the adjusted benchmark interest rate for RMB denominated loans; (iii) the nature and the carrying value of the leased assets. The carrying amount of the leased assets shall be not less than the principal amount under the finance lease in any event; and (iv) provision of approximately 5% buffer for unexpected fluctuations in the growth of the financing balance during the term of the New Finance Lease Framework Agreement.

The Company estimates that the total financing balance of finance lease transaction for the four years ending 31 December 2018 is RMB10,800 million, RMB22,000 million, RMB24,000 million, RMB26,000 million, represents a year-over-year growth rate of approximately +390.9%, +103.7%, +9.1% and +8.3% respectively.

- 48 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

As far as the actual historical total balance is concerned, we note that during the past two years and ten months ending 30 October 2015, the finance lease balance for the Group has increased significantly from RMB600 million up to RMB7,250 million, representing a compound annual growth rate of approximately 289.3%. We also notice that the State Council issued a guideline in August 2015 to further promote the development of the finance lease sector with the aim to substantially increase the penetration rate of finance lease application by 2020. Upon our due diligence review from the 2014 annual report of the Company (being the latest published information available for machinery as a separately disclosed item), we note that the audited total net carrying amount of the Group's machinery as at 31 December 2014 amounted to approximately RMB53,853 million, which was more than twice the estimated total finance lease size for each of the three years ending 31 December 2018. By reviewing the sample finance lease contracts of the Group and the disclosure on the finance lease contracts of other listed companies, we understand that the carrying amount of the relevant machinery shall be not less than the principal amount under the finance lease in any event.

Considering:

(i)

the significant growth in the actual historical total finance lease balance of the Group during the past two years and ten months ending 31 October 2015;

(ii)

the Chinese government's recently issued guideline aiming at substantially increase the penetration rate of finance lease by 2020; and

(iii)

the Group has more than sufficient total net carrying amount of machinery to support the estimated total finance lease balance for each of the three years ending 31 December 2018,

we are of the view that the estimated growth rate of finance lease balance in the four years ending 31 December 2018 is fair and reasonable.

- 49 -

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

As far as the connected balance is concerned, we note that the proposed annual caps for the three years ending 31 December 2018 with Chinalco Lease at RMB10,000 million represents a substantial increase over the estimated annual balance of finance lease with Chinalco Lease in 2015. In this respect, we understand from management of the Company that the estimated balance of finance lease with Chinalco Lease in 2015 of RMB1,400 million merely represents the maximum amount that Board of Directors are authorised to approve without seeking for Independent Shareholders' approval. We have enquired and understand from the Company that in practice during 2015, the Group already has such size of production equipment (in relation to alumina, electrolytic aluminum, mining and energy power) and such demand for finance lease funding to accommodate for the proposed annual caps for each of the three years ending 31 December 2018 with Chinalco Lease at RMB10,000 million.

We have further enquired and understand from the Company that Chinalco Lease itself has sufficient source of funding to provide not less than RMB10,000 million (being the relevant proposed annual cap size) of finance lease business to lessees based on the size of its current authorised registered capital and its external bank borrowings resources in compliance with the relevant laws and regulations, out of which RMB10,000 million worth of finance lease business quota is allocated to the Group based on the internal strategy of Chinalco.

In consideration of the foregoing, we concur with the Board's view that the proposed annual caps under the New Finance Lease Framework Agreement represents the Group's future business development plans and its demand for the finance lease services provided by Chinalco Lease arising from the Group's daily operation and development and we are of the view that the proposed annual caps are fair and reasonable so far as the Independent Shareholders are concerned.

LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

(iii)

the Company will allow, and will procure that the counterparties will allow, the auditors of the Company with sufficient access to the relevant records of the continuing connected transactions under the New Finance Lease Framework Agreement for the purpose of reporting on the continuing connected transaction. The Directors must state in the annual report whether its auditors have confirmed the matters stated in paragraph (ii) above; and

(iv)

Having considered, in particular, (i) the restriction of the value of the continuing connected transactions under the New Finance Lease Framework Agreement by way of the proposed annual caps thereunder; (ii) the internal control measures in place to ensure the Company's conformity with the pricing policies from time to time; and (iii) the ongoing review by the independent non-executive Directors and the auditors of the Company of the terms of the continuing connected transactions under the New Finance Lease Framework Agreement and the proposed annual caps thereunder not being exceeded, we are of the view that there are appropriate measures in place to govern the conduct of the relevant continuing connected transactions and safeguard the interests of the Independent Shareholders.

Recommendation

Having taken into account the above principal reasons and factors, we consider that the terms of the New Finance Lease Framework Agreement (including the proposed annual caps thereunder) are fair and reasonable and that the transactions contemplated under the New Finance Lease Framework Agreement (including the proposed annual caps thereunder) are entered into in the ordinary and usual course of business of the Company, on normal commercial terms and in the interests of the Company and the Shareholders as a whole.

- 52 -
