Sampling Mineral Deposits
March 2007 by Staff
The accurate sampling of mineral deposits for testing and analysis is perhaps the most important step involved in both mineral exploration and development. It is a critical factor in initial prospecting efforts and the preliminary investigation of grassroots exploration projects, yet sampling is often performed in a haphazard and incomplete fashion during the early stages of prospecting and exploration activities.Kings Valley Project Hopes to Meet Lithium, Uranium Demand
Few states in the United States have seen mining activity equal the State of Nevada in recent decades. The state is mineral-rich and possesses a regulatory apparatus that encourages mining activity.
Gondwana Gold and Diamonds
Some 250 million years ago, the Earth had just one supercontinent, known as “Pangaea.” For whatever reason, the supercontinent began to break apart. South America and Africa remained joined, as “Gondwana,” until 65 million years ago, when they split apart. The obvious “fit” of South America with Africa was noted by geologists back in the 19th century, but it was not until Alfred Wegener came out with his “continental drift” hypothesis in 1912 that people took note.

I stared out across the Yukon River. I estimated the river at this point to be a mile wide. An occasional log floated by in the tan-colored water.
A 'Rare' Opportunity for America
All of which brings us back to the question of why we rely so heavily on China in the first place. America’s economy is heavily dependent upon energy and telecommunications, but does that require Chinese manufacturing? Clearly not.
Recovering Values from Black Sands
Every placer miner has to deal with it in one form or another, and some locations have it far worse than others, but nearly every placer has at least some of it: black sand. It collects in our concentrates and gets in the way of recovering our fine gold.
