History & Geology
$50 Million in Gold From 1857 Shipwreck Approved for Sale
March 2018 by Associated Press
The gold is all for sale. Just one tiny coin alone could go for $1 million because of its combination of rarity and the history behind it...
Critical Metals: Lithium
Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
Calcite and Limestone
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
Copper Deposits of Alaska
Only the famous Kennecott copper mine was able to continue operating through the Depression owing to the exceptional richness of its ore.
Critical Minerals: Tungsten
Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds.
Exploring Iron Oxide Copper Gold Deposits
The excitement over IOCG deposits began with the discovery of a monster deposit at Olympic Dam in Australia in 1976. The discovery was accidental as the operator was searching for strata-bound copper deposits.
The Preacher of Sheeps**t Flats
It seemed that the preacher always gave the same answer to anyone who asked where his gold had come from. His answer was, “If you know your gold, you can find it. However, you will have to find it the hard way, the way I found it.”
