the mine's two ore bodies are part of the gold-rich carolina slate belt rock package that runs through the upstate piedmont foothills. the operator of the mine, the ridgeway mining company, is a subdivision of kennecott minerals. kennecott is a subdivision of rio tinto which is one of the world's largest mining companies.
a company was organized and some $85,000 spent in building a rough wagon road from acton up aliso canyon, over mill creek summit, and down to the monte cristo gold mine. heavy mining machinery was transported in and assembled, and buildings were erected. the first account of any extensive work in the monte cristo gold mine appeared in 1895.
erie mining company previously mined ore and there is currently ongoing testing to mine new minerals. kinney pop. 169 is an old mining boomtown on the iron range, located between buhl and mountain iron. mountain iron pop. 2,869 is home to minntac, the world's largest taconite processing plant.
the ore minerals are gold and silver tellurides, with accessory fluorite. the cripple creek & victor gold mining company formed in 1976 as a joint venture to restart mining in the district. from 1976 to 1989, the company produced 150,000 troy ounces 4.7 t of gold by reprocessing tailings and mining two small surface deposits.

the porcupine gold rush was a gold rush that took place in northern ontario starting in 1909 and developing fully by 1911. a combination of the hard rock of the canadian shield and the rapid capitalization of mining meant that smaller companies and single-man operations could not effectively mine the area, as opposed to earlier rushes where the gold could be extracted through placer mining .

heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. h
kimberly is a ghost town in the northwest corner of piute county, utah, united states.located high in mill canyon on the side of gold mountain in the tushar mountains, kimberly was formerly a gold mining town. originally settled in the 1890s, it lasted until 1910. kimberly had a minor rebirth in the 1930s, but has been uninhabited since about 1938.

the anglo saxon mine and groganville township represent a place with potential to yield information that will contribute to the understanding of north queensland's gold-mining industry in the late 19th century. the gully from the mine south through groganville township to the limestone cemetery is a well-preserved cultural landscape and a rare .
