Prospecting Homonyms
April 2012 by W. Dan Hausel
Three homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
The Goldfield Mining District -- Then and Now
In 1983, some of the ore yielded more than 2,500 ounces of gold within 30 feet of the surface. The shoot pinched to a narrow vein.
Placer Mining At Chititu Creek, Alaska
There is reason to believe these stream valleys are still rich with gold, silver and copper.
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: Titanium—Part II
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
The Pedro Gold Dredge
The decision was made to move the dredge intact, a massive undertaking indeed. The goal was to move it only one mile to the Busby’s Chicken Gold Camp, but what a mile that was to be.
The Amazing Mineral Tourmaline
It is a gemstone, and yet it is also closely associated with many types of metal ores. It's valuable itself but often points toward other valuable minerals—that is certainly something prospectors want to know more about!
Gold From Cemented Gravels
The truth is that cemented gravels are really not all that complex. There is no mystery of how gold grew there or somehow wormed its way into these solid gravels.
