Potentially, it could contain 2 to 4 times more gold than the famous Homestake Mine. It is slated for production in This is a blog about the geologists who found this great deposit.

The deposits are similar to the one at the Copper Mountain Mine, but none was of significant size. Indication of production: Yes; small: Reserve estimates: None. Production notes: From to , the Copper Mountain Mine produced , pounds of copper, 10, ounces of silver, and ounces of gold from 5, tons of ore. The U.S. Geological Survey completed the first-ever global assessment of undiscovered copper resources for the two most significant sources of global copper supply: porphyry copper deposits and sediment-hosted stratabound copper deposits. The geology-based study identified areas for undiscovered copper in 11 regions of the world. Estimated.

GEOGRAPHY The Nizina district (see fig. 12) is on the southeast flank of the Wrangell Mountains, a rugged range with several peaks higher t feet. Most of the known copper deposits are in the part of the district shown on plate In this area the relief in places exceeds 5, feet.

The Ambler district is located along the southern margin of the Brooks Range, Alaska. Mineral exploration since the late s in this remote area has led to the discovery of a number of volcanogenic massive sulfide deposits and several carbonate-hosted copper deposits.

P. Morgan and Simon Syndicate purchased the Kennicott-Bonanza copper mine and had majority control of the Alaskan steamship and rail transportation. The syndicate also was in charge of a large part of the salmon industry.Prospectors also sought and found other minerals in Alaska.

Deposits of copper, coal, silver, mercury, platinum, and tin were among the others found and mined in Alaska. The copper deposits in the Copper River basin had long been of interest. Inan Ahtna chief, Nicolai, led prospectors to his own copper deposits.
