That part of a measured or indicated mineral resource that could be economically mined, demonstrated by at least a preliminary feasibility study that includes adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate (at the time of reporting) that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that may occur when the material is mined. Mineral reserves are those parts of mineral resources that, after applying all mining factors, result in an estimated tonnage and grade that, in the opinion of the qualified person(s) making the estimates, is the basis of an economically viable project after taking account of all relevant processing, metallurgical, economic, marketing, legal, environment, socio-economic and government factor. The term "mineral reserve" need not necessarily signify that extraction facilities are in place or operative or that all governmental approvals have been received, although it does signify that there are reasonable expectations of such approvals. Mineral reserves are subdivided into proven mineral reserves and probable mineral reserves.
