Mar 21, 2019· Most companies mine copper as a coproduct in conjunction with other metals, such as molybdenum, zinc, nickel or lead, and it is typically found in large sulfide and porphyry deposits. These are some of the top active copper mining operations in Canada: Highland Valley Copper Operations. Location: 17 kilometres west of Logan Lake,
Porphyry deposits represent an important resource of copper; however, they are also important sources of gold and molybdenum with porphyry deposits being the dominant source of the latter. In general, porphyry deposits are characterized by low grades of ore mineralization, a porphyritic intrusive complex that is surrounded by a vein stockwork ...
Mining for ore isn''t what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
Doré Copper''s subsidiary CBAY Minerals owns 50% of Gwillim. The other 50% is owned by Argonaut Gold. Doré Copper is the operator. The Gwillim mine operated between 1974 and 1976 and again from 1980 to 1984. In total 245,245 short tons were mined at a .
The Reed Gold Mine in Cabarrus County, North Carolina, southwest of Georgeville, produced about 50,000 troy ounces (1,600 kg) of gold from deposits of lode and placer. Gold was produced in 15 districts, nearly all of them in the state''s Piedmont region. The total production of gold is estimated at million ounces of troy ( tonnes). Oregon
First discovered in 1964 by Cominco, between 1991 and 1999 the Snip deposit produced million ounces grading an average of g/t gold. The Eskay Creek mine was discovered in 1988 by junior ...
Heading directly southeast from the copper deposit, you''ll encounter three copper veins nestled in the rock wall. Similar to Landview Lighthouse, you should pull in about twentyfour to thirtytwo copper ore depending on how many times you''re allowed to mine each ore vein and the deposit.
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 ( 2% copper and gram per tonne gold).

Vein deposits include most gold mines, many large silver mines and a few copper and leadzinc mines.. Veins commonly consist of quartz (sometimes of several varieties such as amethystine or chalcedony) usually occurring as interlocking crystals in a variety of sizes or as finely laminated bands parallel to the walls of the vein.
Jul 01, 1993· The first metals used by Early Man appear to have been copper, gold and silver; produced by charcoal smelting (reduction) of the "oxide ore" caps from a variety of different orebody types that included veins; although much of the VEINTYPE ORE DEPOSITS: INTRODUCTION 207 gold was likely derived from placers.

In many gold mines exploited during the gold rushes of the 19th century, vein material alone was typically sought as ore material. In most of today''s mines, ore material is primarily composed of the veins and some component of the wall rocks which surrounds the veins.. The difference between 19thcentury and 21stcentury mining techniques and the type of ore sought is based on the grade of ...
Most polymetallic vein and replacement deposits are zoned such that coppergold ore is proximal to intrusions, whereas leadzincsilver ore is laterally and vertically distal to intrusions.

Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
The Pebble Mine would produce 70 million tons of gold, molybdenum and copper ore a year and create a pit 1,970 feet (600 meters) deep. A new road, pipeline and power plant would be built ...
Oct 17, 2019· Epithermal gold deposits are among the richest gold deposits in the world with some bonanza grade ore shoots containing more than 1000 g/t gold, or in other words, a kilogram of gold for every tonne of rock mined.
