Rare Silver Nuggets And Their Origins
March 2018 by Michael Roney
Silver nuggets have been described as “ultra-rare,” “prized” and “unique.” Naturally occurring silver nuggets are rare enough to suggest caution when purchasing. Fakes have reportedly been produced and misrepresented for sale as genuine specimens.
Simple Rules of Gold Geology: Comparing Epithermal and Mesothermal Deposits
Geology is a science of general tendencies with frequent exceptions, not one of hard and fast rules that are always true and never vary. For almost every well-accepted rule of gold deposits, I can point you to a number of important exceptions.
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.
Detecting for Gold in Australia—The Kimberley Trip
The hair stood up on the back of my neck when I saw this, especially the nice patches of wash in the bottoms of the gullies, a sure sign of an auriferous source being nearby.
Undiscovered Placer Deposits in Alaska
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Third Largest Nugget in Existence Returns to Dallas
While the bullion value of the nugget is already substantial, the size and rarity of the Ausrox Nugget combine to make its worth invaluable in the collector market.
Prospecting for Silver Deposits
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
Heavy Sands Mining
Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
