N. Mine Development Costs	n. Mine Development Costs Mine development costs include engineering and metallurgical studies, and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Costs incurred at a mine site before proven reserves have been established are expensed as mine development costs. At the point proven reserves have been established at a mine site, such costs will be capitalized and will be written off as depletion expense as the minerals are extracted. As of May 31, 2015, none of the mine concessions met the requirements for proven reserves; development costs are therefore expensed.
