Established Mine Full plant and equipment including crushers, ball mill, shaker tables, wave table. Mostly gravity recovered gold; History dating back to 1869, with historic workings and small scale operations mining high grade sediment hosted gold veins and breccias
1 Over the past 15 years, mine to mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

The Copper Mountain mine is located about 20 km south of Princeton, British Columbia and 300 km east of the port of Vancouver. The Copper Mountain mineral claims cover approximately 18,000 acres and consist primarily of 135 crown grants, 176 mineral claims and 14 mining leases.
Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex.It is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions

History. In 1923 the orebody containing lead, zinc and silver was discovered by the miner John Campbell Miles.Mount Isa Mines Limited was one of three companies founded in 1924 to develop the minerals discovered by Miles, but production did not begin until May 1931. The other two companies were Mount Isa Silver Lead Proprietary and Mount Isa South.
The AMIRA Gold Processing Technology project is a collaborative industry funded project which has operated since 1984. Over the last 33 years the project has covered a wide range of topics within the general areas of gold ore processing and environmental management of tailings.
