March 2015 by Chris RalphQ: Is this gold or some other metal?
I regularly get inquiries along the line of: “Hey, I found this rock, and I think it might be gold ore. How can I tell?” Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
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.
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
