Mineral Properties, Plant and Equipment | 12. MINERAL PROPERTIES, PLANT AND EQUIPMENT
Acquisition costs of investment and non-producing properties together with costs directly related to mine development expenditures are capitalized. Exploration expenditures on investment and non-producing properties are charged to expense in the period they are incurred. Capitalization of evaluation expenditures commences when there is a high degree of confidence in the project’s viability and hence it is probable that future economic benefits will flow to the Company. Evaluation expenditures, other than that acquired from the purchase of another mining company, are carried forward as an asset provided that such costs are expected to be recovered in full through successful development and exploration of the area of interest, or alternatively by its sale. Evaluation expenditures include delineation drilling, metallurgical evaluations, and geotechnical evaluations amongst others. Mineral properties, plant and equipment consist of:
