Fabulous Florence—The Golden Town of Idaho
May 2012 by Alan Trees
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 Golden Streams of Butte County, California
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.
Iron Ores and Iron Mining
For more than 40 years, iron ore prices have been decided by private negotiations conducted between the largest of the iron miners and the largest steel producers. These two sides dominate both the spot and contract iron ore markets.
Gold in The Silver Crown District, Wyoming
When my field assistant Jay Roberts and I entered the mine, it appeared as if someone just walked out of the mine, turned off the lights and never returned.
Gold Deposits of the Ivory Coast
Ivory Coast has considerable gold reserves, and this nation has the largest area of greenstone belts prospective for gold in the continent.
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.
It Pays to Know Your Bedrock
On our last trip, we brought ropes and went down the first waterfall forty vertical feet, only to be confronted by a second, sixty-foot-high, overhanging waterfall that emptied into a slot canyon.
Gold of the Iditarod Mining District, Alaska
It was the middle of winter and the valley was covered in snow, making prospecting a matter of sinking shafts in the ground.
