Mineral Deposit ValueHow to Calculate the Potential

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).

Innovations Introduction to Copper Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
