Project Overview
The Resolution Copper deposit ranges from 5,000 to 7,000 ft (1,500 to 2,130 m) below the surface. The deposit's average grade is estimated at 1.5% copper 1. The proposed underground mine is expected to become the largest copper mine in North America, capable of producing up to 25 percent of U.S. copper demand each year.

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.
The Peak Years of British Copper Mining
Copper mining had been resumed there in 1757 after a gap of centuries, and for a good many years this mine regularly produced 2,000 to 3,000 tons of copper per annum, the workings being carried down progressively to 1,030 ft below the surface. The Parys ore was a complex sulphide. With that inconsistency which has been the fate of so many mines ...
Mining copper ore
Mining tin ore can be done in several different places but one of the best is in the dwarven mines underneath Falador. The output is calculated having full stamina at all times. It should be noted that you will be getting sedimentary geodes while mining. The geodes can later be opened to retrieve spirit shards and different gems. The player should use the best …
