Exploring and Mining for Uranium
August 2011 by Chris Ralph
For a time uranium was more popular with prospectors than gold, but this is no longer true, and it has been decades since it was common to see individuals armed with Geiger counters out in the field.
Prospecting for Pegmatites
…in some cases pegmatites have produced individual mineral crystals that are enormous, attaining lengths of over 40 feet long, and many of the world’s largest mineral crystals are examples that were found within pegmatite deposits.California: The Land of Big Nuggets—Part I
The nugget sat there in plain sight, though it was covered in dirt, while hundreds of people had passed that way every day.
The Beatty Mining District of Nevada
The Beatty Mining District in south-central Nevada has been one of the most productive Mining Districts in the state, producing millions of ounces of gold together with silver, fluorite, mercury and other valuable minerals.
Fabulous Florence—The Golden Town of Idaho
In September 1861, on a round-about prospecting journey homeward, five California gold miners discovered gold in the area now called Florence. While watering the horses, one of the men noticed a golden color on a piece of slate bedrock in the stream...
The Geology of Diamond Deposits
New theories have been developed and they may lead to new discoveries and give prospectors some new insight on where to look for diamonds.
Gold, Quartz & Chalcedony—Part II
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
Gold Placers of the Kenai Peninsula, Alaska
The biggest obstacle is that like many streams on the Kenai Peninsula, high water during the summer months from snow melt and rain can make dredging nearly impossible. The best dredging is in the colder months of the year.
