And they continued to report it as such up to the last 10K/A:

c)   Mineral Property Exploration
The Company was in the exploration stage and had not yet realized any revenue from its planned operations.  Mineral property acquisition costs are capitalized. Additionally, mine development costs incurred either to develop new ore deposits and constructing new facilities are capitalized until operations commence.  All such capitalized costs are amortized using a straight-line basis, based on the minimum original license term at acquisition, but do not exceed the useful life of the capitalized costs.  Upon commercial development of an ore body, the applicable capitalized costs would then be amortized using the units-of-production method.  Exploration costs, costs incurred to maintain current production or to maintain assets on a standby basis are charged to operations.  Costs of abandoned projects are charged to operations upon abandonment.  The Company evaluates, at least quarterly, the carrying value of capitalized mining costs and related property, plant and equipment costs, if any, to determine if these costs are in excess of their net realizable value and if a permanent impairment needs to be recorded.  The periodic evaluation of carrying value of capitalized costs and any related property, plant and equipment costs are based upon expected cash flows and/or estimated salvage value in accordance with guidance issued by the FASB, "Accounting for Impairment or Disposal of Long-Lived Assets."  Subsequent to November 30, 2014, the Company determined that pursuing the development of its oil and gas assets was no longer economically feasible.  As a result, the Company recorded an impairment of the assets equal to 100% of their previous carrying value.
