During 2023, Jaidev's Copper Mine Inc. (JCMI) built the infrastructure for an open pit copper mine in a remote area in Northern British Columbia at a total cost of $20 million paid in cash. The mine is expected to produce 800,000 tonnes of copper over its estimated useful life of 8 years. The BC government's approval granted to JCMI was conditional upon the company remediating the site and establishing a wildlife reserve. The estimated cost of remediation is $4.5 million. An appropriate interest rate for this obligation is 4%. Assume that JCMI has grouped the $20 million construction costs and the remediation asset in an account called "Mine assets," and it uses the units-of-production method to depreciate this asset. JCMI began mining operations in January 2024 and during the year, it mined 60,000 tonnes of copper. In 2025, it increased its production to 89,000 tonnes of copper. Its year-end date is December 31. Assume that JCMI elects to report its financial results in accordance with Accounting Standards for Private Enterprise (ASPE). Requirement a.
