Announcement on New Accounting Policies and Accounting Estimation

The Company and all members of the board of directors warrant the truthfulness, accuracy and completeness of the information disclosed herein, and accept joint responsibility for any misrepresentation or misleading statement contained in or material omission from this announcement.

I.

SUMMARY OF THE NEW ACCOUNTING POLICIES AND ACCOUNTING ESTIMATION

On 23 January 2013, the Company acquired 70.82% equity interest in Ningxia Electric Power Group Co., Ltd.* () (now renamed as Chalco Ningxia Energy Group Limited* ()), which has been included into the scope of the consolidated statements of the Company. An energy segment was also added in the business segments of the Company. Therefore, the 2013 interim report added certain presentation of accounting policies and accounting estimation for the energy segment, including:

1.

Difference between the presentation in 2013 interim report and 2012 annual report: (1) depreciable lives of fixed assets; (2) amortization of mining rights for intangible assets; (3) safety production expenses.

In particular (each order number shown below is consistent with the interim report):

Mining rights and mineral exploration rights

As presented in the 2012 annual report:

Mining rights are initially recorded at cost which includes payments of consideration for extraction rights and other direct costs. Amortisation is provided on a straight-line basis according to the shorter of the expiration date of the mining certificate or the mineable period of natural resources. As for mining rights, the estimated useful lives are represented by the expiration date in the mining certificate range from 3 to 30 years. Mineral exploration rights are initially recorded at the cost of the acquisition and adopt the same method as the one for the mining rights to amortise since the exploration rights convert to the mining rights and begin to produce.

As presented in the 2013 interim report:

The Group's mining rights include coal, bauxite and other mining rights.

Mining rights are initially recorded at cost which include payments of consideration for extraction rights and other direct costs.

Amortisation of bauxite and other mining rights is provided on a straight-line basis according to the shorter of the expiration date of the mining certificate and the mineable period of natural resources. As for mining rights, estimated useful lives are represented by the expiration date in the mining certificate ranging from 3 to 30 years.

Coal mining rights are amortised on a unit-of-production basis according to the proven and probable coal reserves.

Mineral exploration rights are initially recorded at the cost of the acquisition and adopt the same method as the one for the mining rights to amortise since the exploration rights convert to the mining rights and begin to produce.

(28)

Safety production expenses

As presented in the 2012 annual report:

The safety production expenses accrued in accordance with the regulations are recorded in the relevant product cost or profit or loss of the current period and special reserve. The treatment for usage of the safety production expenses depends on whether the fixed assets are formed or not. When such safety production expenses are applied and related to revenue expenditures, specific reserve is directly offset. When fixed assets are incurred, they are included in construction in progress and transferred to fixed assets when the status of the assets is ready for intended use. They are then offset against specific reserve based on the amount included in fixed assets while corresponding amount is recognised in accumulated depreciation. Such fixed assets are no longer depreciated in subsequent periods.

As presented in the 2013 interim report:

(30)

Safety production expenses, repair and maintenance cost and other similar cost

The Group, according to the requirement of government authorities in PRC, accrues repair and maintenance cost, safety production cost and other similar cost to maintain the production in the mining area and as expenses for equipments overhaul, safety expenses for coal production and coal mining structure, safety expenses for transportation business and other relevant expenses. Such expenses are recorded in the relevant product cost or profit or loss of the current period and special reserve. The treatment for usage of the safety production expenses depends on whether fixed assets are formed or not. When such safety production expenses are applied and related to revenue expenditures, specific reserve is directly offset. When fixed assets are incurred, they are included in construction in progress and transferred to fixed assets when the related assets reach the expected use condition. They are then offset against specific reserve based on the amount included in fixed assets while corresponding amount is recognised in accumulated depreciation. Such fixed assets are not depreciated in subsequent periods.

2.

The newly added presentation in the 2013 interim report that was not contained in the 2012 annual report: (1) Exploration and evaluation expenditure; (2) mine rehabilitation provision; (3) coal reserve and resource estimates and units-of-production depreciation for mining rights in significant accounting estimation and judgment.

In particular (each order number shown below is consistent with the interim report):

(14)

Exploration and evaluation expenditure

Exploration and evaluation assets include topographical and geological surveys, exploratory drilling, sampling and trenching and activities in relation to commercial and technical feasibility studies, and expenditure incurred to secure further mineralisation in existing coal bodies and to expand the capacity of a mine. Expenditure incurred prior to acquiring legal rights to explore an area is written off as incurred. Exploration and evaluation assets acquired in a business combination are initially recognised at fair value. They are subsequently stated at cost less accumulated impairment. When it can be reasonably ascertained that a mining property is capable of commercial production, exploration and evaluation costs are transferred to tangible or intangible assets according to the nature of the exploration and evaluation assets. If any project is abandoned during the evaluation stage, the total expenditure thereon will be written off.

(23)

Mine rehabilitation provision

Site restoration, decommissioning, environmental cleanups and other present obligations due to mining activities are recognized as estimated liabilities when it is probable that an outflow of economic benefits will be required to settle the obligation, and the amount of the obligation can be measured reliably.

A provision is initially measured at the best estimate of the expenditure required to settle the related present obligation. Factors surrounding a contingency, such as the risks, uncertainties and the time value of money, are taken into account as a whole in reaching the best estimate of a provision. Where the effect of the time value of money is material, the best estimate is determined by discounting the related future cash outflows. The increase in the discounted amount of the provision arising from passage of time is recognised as interest expense.

The carrying amount of provisions is reviewed at each balance sheet date and adjusted to reflect the current best estimate.

(31)

Significant accounting estimation and judgment

(b)

Coal reserve and resource estimates

Coal reserves are estimates of the amount of coal that can be economically and legally extracted from the Group's mining properties. The Group estimates its coal reserves and mineral resources based on reserve reports compiled by appropriately qualified persons relating to the geological data on the size, depth and shape of the coal body, and this requires complex geological judgments to interpret the data. The estimation of recoverable reserves is based upon factors such as estimates of commodity prices, future capital requirements, and production costs along with geological assumptions and judgments made in estimating the size and grade of the coal body. Changes in the reserve or resource estimates may impact upon the carrying value of exploration and evaluation assets, mine properties, property, plant and equipment, goodwill, provision for rehabilitation, recognition of deferred tax assets, and depreciation and amortisation charges.

(c)

Unit-of-production depreciation for mining rights

Estimated recoverable reserves are used in determining the amortisation of mining rights. This results in an amortisation charge are proportional to the depletion of the anticipated remaining life of mine production. Each item's life, which is assessed annually, has regard to both its physical life limitations and present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves and estimates of future capital expenditures.

II.

IMPACTS OF THE NEW ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES ON THE COMPANY

The addition of accounting policies and accounting estimates to the interim report are events arising from the incorporation of Chalco Ningxia Energy Group Limited* into the consolidated statements of the Company and do not constitute a change in the accounting policy and accounting estimates. Hence, no retrospective adjustment is required, nor is the financial report of the Company affected.
