Mine Exploration and Development Costs

The Company expenses exploration costs as such in the period they occur. The mine development stage begins once the Company identifies ore reserves which is based on a determination whether an ore body can be economically developed. Expenditures incurred during the development stage are capitalized as deferred development costs and include such costs for drift, ramps and infrastructure. Costs to improve, alter, or rehabilitate primary development assets which appreciably extend the life, increase capacity, or improve the efficiency or safety of such assets are also capitalized. The development stage ends when the production stage of ore reserves begins. Amortization of deferred development costs is calculated using the units-of-production method over the expected life of the operation based on the estimated recoverable mineral ounces.
