Year	Details	$ Amount
August 2016	Right to explore	500,000
2016 - 2017	Exploratory study and drilling	4,500,000

At the beginning of 2018, the technical feasibility and commercial viability of mining the diamond deposit were confirmed. The companys experts estimated there were 20 million carats of diamonds that could be commercially exploited. From March 2018 to June 2019, the company undertook the following capital investments:

	Costs	Estimated Life (as at 30 June 2019)
Mine buildings	$5,600,000	20 years
Processing plant	$12,000,000	15 years
Other equipment	$3,000,000	6 years

Mine buildings cannot be economically removed from the mine location, but the processing plant and other equipment can be economically removed and have alternative uses.

On 30 June 2019, Tintin Ltd estimated that the costs of restoration as a result of development and construction activities would be $800,000 at the end of the mines life because the company wished to portray itself as a responsible corporate citizen. A discount rate of 8% was identified as relevant for its diamond operation.

Production commenced on 1 July 2019. It will take 9 years to exhaust this economically recoverable reserves, after which time the mining property is expected to have a residual value of $200,000. Activities for the year ended on 30 June 2020 were as follows:

Carats of diamonds mined......................................................................... .3,000,000

Carats of diamonds sold................................................................................ 2,800,000

Selling price of diamonds.......................................................................... $18 per carat

Production costs (excluding depreciation and amortisation)..................... $20,000,000

Administration expenses.............................................................................. $1,800,000

Selling expenses............................................................................................. $800,000

REQUIRED:

1.Assume all costs incurred during the exploration and evaluation phases were capitalised, what are the amortisation expense and the total depreciation expense for the year ended 30 June 2020? No journal entry is required.

2.What is the cost of goods sold for the year ended 30 June 2020?

3.What is the finance cost related to the restoration for the year ended 30 June 2020? No journal entry is required.

4.Tintin Ltd incurred stripping costs of $300,000 to remove overburden (e.g., soil, rock, and other materials) during the production phase. Geologists evaluated the overburden removed during this stripping process and suggested the overburden had high ratio of ore to waste. Advise and briefly explain the appropriate accounting treatment relating to the stripping costs. No journal entry is required.
