Schedule 1

Accounting principles (clause 1.1)





1 Summary of significant accounting policies

The management of Minerva Joint Venture have determined that the joint venture is not a reporting entity and accordingly this financial
report is a special purpose financial report which has been prepared in accordance with the requirements of the joint venture agreement, and the requirements of the following applicable Australian Accounting Standards.

AASB 1031: Materiality

Whilst the recognition
and measurement requirements of the Australian Accounting Standards have been complied with, not all disclosure requirements of the Australian Accounting Standards have been complied with, therefore, no other applicable Accounting Standards,
Australian Accounting Interpretations or other authoritative pronouncements of the Australian Accounting Standards Board have been applied.

The report is also prepared on an accrual basis and is based on historical costs and does not take into account changing money values or, except where
specifically stated, current valuations of non-current assets. The accounting policies adopted are consistent with those of the previous year unless otherwise stated. Comparative information is reclassified where appropriate to enhance
comparability.

The following is a summary of the material accounting policies adopted by the entity in the preparation of the financial
report. The accounting policies have been consistently applied unless otherwise stated.

(a) Cash and cash equivalents

For the purpose of the cash flow statement, cash includes:

i) cash on hand and at call deposits with banks or financial institutions, net of bank overdrafts; and

ii) investments in short-term money market instruments with maturity periods of less than 3 months.

(b) Loans and receivables

Trade receivables, loans and other receivables are recognised
initially at fair value and subsequently measured at amortised cost using the effective interest method, less provision for impairment.

Debts
which are known to be uncollectible are written off by reducing the carrying amount directly. A provision for impairment is made when there is objective evidence that the full amount is not collectible. Significant financial difficulties of the
debtor, probability that the debtor will enter bankruptcy or financial reorganisation, and default or delinquency in payments are considered indicators that the trade receivable is impaired. The amount of the impairment provision is the difference
between the assets carrying amount and the present value of estimated future cash flows, discounted at the original effective interest rate. Cash flows relating to short-term receivables are not discounted if the effect of discounting is
immaterial.

The amount of the impairment loss is recognised in the income statement. When a receivable for which an impairment provision had
been recognised becomes uncollectible in a subsequent period, it is written off against the provision account.

(c) Inventories

Coal stocks are stated at the lower of cost and net realisable value. Costs are assigned on a weighted average basis and include direct
materials, direct labour and an appropriate proportion of variable and fixed overheads. Net realisable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary
to make the sale.

(d) Overburden in advance

Overburden in advance comprises the accumulation of expenses incurred to enable access to the coal seam, and includes direct removal costs, machinery and plant running costs.

(e) Property, plant and equipment

Each class of property, plant and equipment is carried at cost less, where applicable, any accumulated depreciation and accumulated impairment losses. The carrying amount of freehold land and buildings
and plant and equipment is reviewed to ensure it is not in excess of the recoverable amount from these assets.

Plant and equipment

The depreciable amount of all fixed assets, including buildings and capitalised leased assets, but excluding freehold land, is depreciated
on a straight line or declining balance basis to allocate their cost, net of their residual values, over their estimated useful lives to the entity commencing from the time the asset is held ready for use, as follows.

Buildings 12 years

Plant and equipment 2.5 to
12 years

Leased plant and equipment 2.5 to 12 years

|L        31 August 2010 |  | M        33,213,012          |  | N        21,555,633                  

(f) Intangible assets

Rail access rights

Rail access rights have a finite useful life and are carried at cost less, where applicable, any accumulated amortisation and accumulated impairment
losses. The carrying values of rail access rights are reviewed to ensure they are not in excess of their recoverable amounts. The recoverable amount is assessed on the basis described in note 1(h).

Rail access rights are amortised over the life of the mine using a unit of production basis in tonnes as described above for the Minerva mine.
Amortisation is charged to the income statement.

(g) Acquisition of assets

All assets acquired, including property, plant and equipment and intangibles other than goodwill are initially recorded at their cost of acquisition at the date of acquisition, being the fair value of
consideration provided plus incidental costs directly attributable to the acquisition.

Where settlement of any part of cash consideration is
deferred, the amounts payable are recorded at their present value, discounted at the rate applicable to the entity as if a similar borrowing were obtained from an independent financier under comparable terms and conditions. The unwinding of the
discount is treated as a finance cost.

(h) Recoverable amount of assets and impairment

At each reporting date, the entity assesses whether there is any indication that an asset may be impaired. Where an indication of impairment exists, the
entity makes a formal estimate of recoverable amount. Recoverable amount is the greater of fair value less costs to sell and value in use. Where the carrying amount of an asset exceeds its recoverable amount the asset is considered impaired and is
written down to its recoverable amount.

The amount of the impairment loss is recognised in the income statement. In assessing value in use,
the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Where it is not possible to estimate the
recoverable amount of an individual asset, the entity estimates the recoverable amount of the cash-generating unit to which the asset belongs.

(i) Interest bearing liabilities

Interest bearing liabilities are initially recorded at fair value, net of transaction costs. Subsequent to initial recognition, interest bearing liabilities are measured at amortised cost with any
difference between the initial recognised amount and the redemption value being recognised in the income statement over the period of the interest bearing liability using the effective interest rate method.

All interest bearing liabilities are classified as current liabilities unless there is an unconditional right to defer settlement of the liability for at
least twelve months after the balance sheet date.

(j) Borrowing costs

Borrowing costs incurred during the acquisition, construction or production of a qualifying asset are capitalised during the period of time that is required to complete and prepare the asset for its
intended use. Other borrowing costs are recognised as an expense when incurred.

(k) Leases

Leases of fixed assets where substantially all the risks and benefits incidental to ownership of the assets, but not the legal ownership, are transferred to the entity, are classified as finance leases.
Finance leases are capitalised, recording an asset and a liability equal to the lower of the fair value of the leased property or the present value of the minimum lease payments, including any guaranteed residual value. Leased assets are depreciated
on a straight line basis over their estimated useful lives where it is likely that the entity will obtain ownership of the asset or over the term of the lease. Lease payments are allocated between the reduction of the lease liability and the lease
finance charges for the year.

Lease payments for operating leases, where substantially all the risks and benefits remain with the lessor, are
charged as expenses on a straight line basis over the lease term.

(l) Employee benefits

Annual leave, sick leave and long service leave

Benefits accruing to employees in respect of wages and salaries, annual leave and sick leave are included in trade and other payables. Related on-costs are also included in trade and other payables as
other creditors. Long service leave is provided for when it is probable that settlement will be required and it is capable of being measured reliably.

Employee benefits expected to be settled within 12 months are measured at their nominal values using the remuneration rate expected to apply at the time of settlement. Provisions made in respect of
employee benefits which are not expected to be settled within 12 months are measured as the present value of the estimated future cash outflows to be made by the entity in respect of services provided by employees up to reporting date.

Retirement benefit obligations

Contributions are made by the entity to defined contribution superannuation funds and are charged as expenses when incurred.

(m) Rehabilitation

A provision for
rehabilitation is recognised when there is a present obligation to rehabilitate an area disturbed, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate can be made of the amount of the
obligation. An asset is created as part of the non-current development assets, to the extent that the development relates to future production activities, which is offset by a current and/or non-current provision for rehabilitation.

If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows at a pre-tax rate that
reflects current market assessments of the time value of money and, where appropriate, the risks specific to the liability.

(n) Revenue

Interest revenue is recognised on a proportional basis taking into account the interest rates applicable to the financial assets.

Revenue from the rendering of a service is recognised upon the delivery of the service to the customer.

(o) Goods and Services Tax

Revenues,
expenses and assets are recognised net of the amount of Goods and Services Tax (GST), except where the amount of GST incurred is not recoverable from the Australian Taxation Office (ATO). In these circumstances the GST is recognised as part of the
cost of acquisition of the asset or as part of an item of the expense. Receivables and payables in the balance sheet are shown inclusive of GST.

The net amount of GST recoverable from, or payable to the ATO is included as a current asset or liability in the balance sheet.

Cash flows are included in the cash flow statement on a gross basis. The GST components of cash flows arising from investing activities which are recoverable from, or payable to, the ATO are classified as
operating cash flows.

(p) Foreign currency transactions and balances

Items included in the financial statements of the entity are measured using the currency of the primary economic environment in which the entity operates
(the functional currency). The financial statements are presented in Australian dollars, which is the entitys functional and presentation currency.

Foreign currency transactions during the period are translated into the functional currency at rates of exchange applicable at the dates of each transaction. Monetary assets and liabilities denominated in
foreign currencies at balance date are converted at rates of exchange ruling at that date.

Foreign exchange gains and losses resulting from
the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities, whether realised or unrealised, are recognised in the income statement as they arise except where hedging specific
anticipated transactions.

(q) Critical accounting estimates and other accounting judgements

Management evaluates estimates and judgments incorporated into the financial report based on historical knowledge and best available current information.
Estimates assume a reasonable expectation of future events and are based on current trends and economic data, obtained both externally and within the entity.

There have been no judgements, apart from those involving estimation, in applying accounting policies that have a significant effect on the amounts recognised in this financial report.

Following is a summary of the key assumptions concerning the future, and other key sources of estimation at reporting date that have not been disclosed
elsewhere in this financial report.

Impairment

The entity assesses impairment at each reporting date by evaluating conditions specific to the entity that may lead to an impairment. Where an indicator of impairment exists, the recoverable amount of the
asset is determined. Value-in-use calculations performed in assessing recoverable amounts incorporate a number of key estimates.

No
impairment has been recognised in respect of mine development assets or rail access rights for the reporting period.

Amortisation

The amortisation of mine development assets and rail access rights, and the expensing of overburden removal costs is based on saleable
coal production over estimated economically recoverable reserves. Note 1(e) provides further information regarding economically recoverable reserves. The amount of reserves that may actually be mined in the future and the entitys estimate of
reserves from time to time in the future may vary from current reserve estimates.

(r) Comparative figures

When required by accounting standards, comparative figures have been adjusted to conform to changes in presentation for the current financial year.

(s) Going concern

The
financial report has been prepared on the basis of going concern. The managers have prepared the financial report on a going concern basis as they believe the Joint Venture participants of the Minerva Joint Venture will continue to provide financial
support.

law as a consequence of the mining activities of the Athena joint venture; or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | subdivide and sell to the Athena joint venture the Overlap Land for a price agreed by the parties or, failing agreement, at fair market value as determined by an

Highwall and void



| | (g) | allow the Athena joint venture to gain access to the Athena joint ventures underground mine or mines via a highwall and void of the Minerva mine in accordance
with an access and interface agreement to be agreed between the parties, acting in good faith and using all reasonable endeavours to procure an agreement between the parties provided that:
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | the access by the Athena joint venture must not unreasonably interfere with the operations of the Minerva joint venture; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------



| | (ii) | the Athena joint venture must compensate the Minerva joint venture for any increase in the costs of carrying out the operations of the Minerva joint venture which is

| | (i) | upon the completion of mining by the Minerva joint venture:
| | --- | -----------------------------------------------------------



| | (i) | subject to (i)(ii) below, the Minerva joint venture must, at its cost, rehabilitate the Minerva joint venture area as required by law and in accordance with the terms
of the Minerva mining leases and environmental authorities but not so as to unreasonably interfere with the operations of the Athena joint venture;

| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

transfer any such area to the Athena joint venture for nil cost.

material way the Minerva joint ventures own activities). The Minerva joint venture and the Athena joint venture must, in due course, act in good faith and use all reasonable endeavours to agree in more detail the operational arrangements for
the access to and use of the Surface Infrastructure by the Athena joint venture. To the extent that the Minerva joint venture is still using the Surface Infrastructure, the Minerva joint venture and the Athena joint venture will share all ongoing
operation and maintenance costs on a tonnage utilised basis. To the extent that the Athena joint venture is the sole user, then the Athena joint venture would bear 100% of the ongoing operation and maintenance costs.



| | (k) | allow the Athena joint venture to modify, at their own cost, the Surface Infrastructure where necessary to accommodate the requirements of the Athena joint venture,
provided that the modifications will not unreasonably interfere with the Minerva joint ventures own activities (it being the intention of the parties that these modifications should not adversely impact in any material way the Minerva joint
ventures own activities);
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|---------- | -------------------------------



|4 | If:
|- | ---



| | (a) | either the Minerva joint venture or the Athena joint venture develops new surface infrastructure on or in the vicinity of the Athena Tenements or the Minerva joint
venture area (such as new or upgraded access roads, rail loading facilities, stockpile areas or CHPP facilities and associated crushing and conveying systems); and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | the joint venture that develops the new surface infrastructure is notified by the other joint venture that they wish to have access to that new surface infrastructure,
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

then the parties must negotiate in good faith, and use all reasonable endeavours, to agree commercial terms upon
which such access will be provided, which terms may include, without limitation, a capital or access charge and an ongoing operation and maintenance charge.
