Economic Feasibility of Mining in the Chichagof and Baranof Islands Area, Southeast Alaska

摘要

Economic prefeasibility studies were conducted on typical mineral deposit types that are found in the Chichagof and Baranof Islands Area. Two factors were addressed in this study: (1) the magnitude of resource that would have to exist, and (2) the recoverable metal value (RMV) that would be necessary to make a deposit economically feasible to mine. The RMV is the combined dollar value of all salable products from a given mineral deposit expressed in $/mt, and is equal to the amount of revenues required before all expenses including royalties, mining and milling capital and operating costs, off-site transportation costs, base smelting charges, and taxes are deducted. The interrelation between these factors is shown in tabular and graphical form.
