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. The definition of proven and probable reserves is set forth in SEC Industry Guide 7. Proven reserves are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; (b) grade and/or quality are computed from the results of detailed sampling; and (c) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established. Probable reserves are reserves for which quantity and grade and/or quality are computed from information similar to that used for proven reserves, but the sites for inspection, sampling, and measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation. In addition, reserves cannot be considered proven and probable until they are supported by a feasibility study, indicating that the reserves have had the requisite geologic, technical and economic work performed and are economically and legally extractable at the time of the reserve determination. 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 November 30, 2014, none of the mine concessions met the requirements for proven reserves; development costs are therefore expensed.
