  Appropriate evaluations, beyond the viability economic technique and, are effected understanding elements modificadores, such as legal, ambient and social factors. The evaluations are demonstrated for the time where if they report the reserves and reasonable justified. Inferred reserve: it is the parcel of the mineral resource inferred by only for consideraes made from trends of the regional geologic bodies, with little knowledge oi precision. 4.1.2.3 .DETERMINAO OF the PRODUCTION SCALE is known that the useful life of a mine is function of the amount and quality of the useful material. They are, however necessary, but not enough conditions. More info: Macy’s Inc..

  Many other factors will exert pondervel influence: all the possible profits such as costs of cultivate and of processing, accessible prices of sales, transports, markets, costs of capital etc. they are considered component of the feasibility: Market: it is the salable product and where amount? Mineral reserves: the value of the recoverable ore is enough to justify the investment? It cultivates: can the ores be cultivated the enough low cost? Processing: can the end item be recouped by known methods, in salable pureness and the enough low cost? Cost of the Capital: can the installations be constructed for a capital level that justifies the enterprise? 4.1.2.4 .RISCOS the duration of the activities of cultivates depends on the contained amount of ore and the annually extracted amount. Under the economic point of view, maximum rapidity of extration would be desirable, for selling at a loss the costs of production and amortization of the investments. But under financial aspect great initial investments, nor available or always possible would be demanded to be gotten the convenient taxes. 4.1.2.5 .TIPOS OF CULTIVATES studies For it of viability of a mining enterprise, the determination of the type cultivates to be applied has utmost importance in the calculation of costs. It mines the Open Sky? Method of cultivates of hillsides; Method of you cultivate in diggings; Method ‘ ‘ of the Funil’ ‘ Underground mine? Cut method and Fill; Shrinkage method; Method Open Stop; Method of the Chamber of Pillars; Method of Rise; Top-Slicing method. .
