Question 2

Zenith Mining Ltd paid $3 million for a mineral deposit and spent a further $225 000 in developing the property prior to commencing production on 1 July 20X0.It is estimated that the deposit will produce 25 million tonnes of ore and that the land will have an eventual residual value of $25 000.In addition to the development costs,Zenith spent another $500 000 on infrastructure construction at the mine site.Its mining operations during the year ended 30 June 20X1 resulted in:
$$\begin{array} { l r } \text { Tonnes of ore mined } & 1000000 \\\text { Tonnes of ore sold } & 900000\end{array}$$
The amount to be charged as amortisation of pre-production costs for the year is:

B) $148 000
C) $128 000
D) $133 200

Answer 2

$148 000

Question 3

Australian Accounting Standard AASB 6 Exploration for and Evaluation of Mineral Resources states that exploration and evaluation costs of a mining operation:

C) must be recognised as expenses as they are incurred
D) must be carried forward as an asset until production commences

Answer 3

A

Question 4

Bigspill Gas & Oil Ltd began operations on 1 July 20X1.During the year ended 30 June 20X2,Bigspill explored five different areas of interest and spent $200 000 in each area.The exploration results indicated that three areas were likely to be productive and Bigspill acquired leases over the three areas at costs of $400 000,$720 000 and $480 000 respectively.Under the successful-efforts method of accounting for exploration and evaluation costs in the extractive industries,Bigspill would include which of the following amounts in its statement of financial position as at 30 June 20X2 for Exploration and Evaluation Costs?

Question 5

Ferrous Minerals Ltd paid $2 million for a mine site and has spent a further $500 000 developing the property prior to commencing production.Ferrous estimates that the mine will produce 10 million tonnes of ore and that the land will have a final residual value of $75 000 for sale and use as a waste disposal site.It is also believed that to extract the last 2 million tonnes of ore will require further drilling and excavation work at a cost of an extra $200 000.What is the amortisation rate that should be used to write-off pre-production costs in the first year of production (when it is estimated that 1 million tonnes of ore will be mined):

A) 27.0 cents per tonne

D) none of the above

Question 7

Bigspill Gas & Oil Ltd began operations on 1 July 20X1.During the year ended 30 June 20X2,Bigspill explored five different areas of interest and spent $200 000 in each area.The exploration results indicated that three areas were likely to be productive and Bigspill acquired leases over the three areas at costs of $400 000,$720 000 and $480 000 respectively.Under the expense method of accounting for exploration and evaluation costs in the extractive industries,Bigspill would include which of the following amounts in its statement of financial position as at 30 June 20X2 for Exploration and Evaluation Costs?

A) $2 200 000
B) $1 600 000

A) is inconsistent with the framework of accounting
B) is likely to be accepted for income tax purposes
C) is simple and conservative

Question 11

Australian Accounting Standard AASB 6 Exploration for and Evaluation of Mineral Resources does not identify which of the following phases in the exploitation of mineral,oil or gas deposits?

A) Production
B) Restoration
C) Construction
D) Evaluation

Question 12

Australian Accounting Standard AASB 6 'Exploration for and Evaluation of Mineral Resources' requires the use of the area-of-interest method in accounting for pre-production costs of a mining operation.This method is a special form of the:

A) expense-and-reinstatement method
B) successful-efforts method
C) expense (costs written-off) method
D) full-cost method

Question 13

The expense (or costs written-off method)of accounting for exploration and evaluation costs in the extractive industries would seem to be the most conservative of the suggested methods of accounting for these costs.Conservatism has a long history in accounting and is often used to justify or support many accounting practices.Why then is the expense method not favoured by the Australian Accounting Standards Board? Consider both the benefits and the disadvantages arising from the use of this method.
