The Coeur Rochester Mine
September 2017 by Chris Ralph
One of the reasons I am bringing this article forward to readers now is that the mine personnel are celebrating the production of 150 million ounces of silver since 1986.
It is the second largest gem-quality diamond in history, after the 3,106-carat “Cullinan Diamond” was recovered in South Africa in 1905.
Knowing how and when to deduct the cost and expenses of the vehicles used in the prospecting or mining operation can have significant tax implications.
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
Arizona-based International Silver Inc. is proposing an underground silver and zinc mine in Montana and has asked Butte-Silver Bow County to lease them the surface and mineral rights to hundreds of acres.
US uranium mines produced less than 174,000 pounds in 2019, according to the February Energy Information Administration report. That’s down from 4.9 million pounds in 2014.
