Large Scale Mining

…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.

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.

Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.

I had a chance to visit the operation in person and talk with Neal. I was very impressed and I think our readers could learn a lot about building up a commercial placer operation from scratch…

One of his friends had 700 feet of small-gauge mine track and a hundred-year-old track bender laying out in his back 40; plus he also wanted to join the team. Perfect.

This was no ordinary nugget. It had not traveled very far from its nearby source, and that did mean a lot, as we were searching for the source of several such nuggets found during a gold rush that occurred in 1859.

They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
