The Copper Country is highly unusual among coppermining districts, because copper is predominantly found in the form of pure copper metal (native copper) rather than the copper oxides or copper sulfides that form the copper ore at almost every other coppermining district. The copper deposits occur in rocks of Precambrian age, in a thick sequence of northwestdipping sandstones, conglomerates, .

Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick ), who personified the fact that coppernickel ores resisted refinement into copper.
, the minimum ore concentration necessary for economic mining, when it determined the reserve and resource estimates for the RPA Revised Base Case and RPA Extended Case. Had RPA used an appropriate cutoff grade, the mineral reserve and resource estimates would have been considerably lower, as I demonstrate in this report.
