The Wisdom of Mark Twain—And Tales of Cheating the Unwary Prospector
June 2012 by R. V. Larson
I (enjoy) Twain’s description of a gold mine, “A hole in the ground with a liar at the top.” Some humor here? You bet, but I’m sure he meant it to be a real eye opener as well.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.
Potholes and Other Bedrock Traps
Potholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
Rock and Formations of the Mother Lode Gold Belt
The faulting, folding and shearing that occurred in the Mother Lode belt has created zones of structurally weak rocks or contacts between different types of rock, which has been favorable for the deposition of gold bearing ores.
Prospecting for Diamonds in Kimberlite
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
Gold, Quartz & Chalcedony—Part I
Gold has always been noted to have an affinity for quartz to such a degree prospectors almost always dig on quartz veins in a search for the precious metal.
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.
Epithermal Gold and Silver Deposits
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
