Large Scale Mining

After paying for the mine fleet, mill capital, supplies, fuel, power and labor, at today’s metal prices, does this mine make a profit?

The proposed mine would be built on state-owned land in the Bristol Bay region, near the world’s largest wild sockeye salmon fishery.

If approved, the project would use block caving to extract the remaining ore, most of which is 7,000 feet below ground level.

A few months later, a young, greenhorn lawyer agreed to pay to have it assayed, and the quartz turned out to be rich in both gold and silver.

They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.

I’ve been following the precious metals for decades, and I haven’t seen a move this powerful in many years.

…let’s dive in and take a closer look at these rich gold and silver-bearing minerals to find out what they are, where they form, and how to identify them.

For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.

Polymetallic skarn deposits are an interesting class of deposits that can contain a number of different types of metals.

One of the first things we did while looking at buying the equipment was figuring out how it would dovetail into the milling process we already had in mind.

Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.

We are at a crossroads; either we establish the mining, production and refining of rare earth elements here in the US or we remain subjected to the whims of the Chinese government.

There seem to be two possibilities for the future of this disease and either way there will be an effect on the price of gold.

The same day, while two of us were heading to Vancouver to attend the mining convention, two others from our team were headed to Nevada to begin loading the millsite equipment.

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.

It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.

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.

Many of the Sixteen to One’s challenges arise from its unusual geology and the pocket characteristics of the ore deposits.
