Porphyry copper deposits, which are associated with igneous intrusions, yield about twothirds of the world''s copper and are therefore the world''s most important type of copper deposit. Large copper deposits of this type are found in mountainous regions of western North America and in the Andes Mountains of South America.
Question. Suppose that you are building a new house. It will take about 90 kg (198 pounds) of copper to do the electrical wiring. In order to get the copper in the first place, someone needs to mine solid rock that contains copper, extract the copper minerals, throw away the waste rock, and smelt the copper minerals to produce copper metal.
Before you can calculate the potential mineral deposit value, you first need to gather some specific data regarding the ore body and the individual drill results.. This required data can be found in the mining company''s press releases in which they announce their drill results.Make sure that this data is announced according to the guidelines of National Instrument 43101 (i.e. approved by a
