Prospecting & Detecting
Small-Scale Processing of Hard Rock Ores
December 2014 by Chris Ralph
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.Gold Prospecting for Better or Worse: When a Gold Prospector Goes to a Diamond Mine
As a gold prospector for the past ten years, I thought that I had a fair understanding of the steps necessary to find gemstones.
How Should I Work This Prospect?
How big is the deposit? Are there boulders you will need to move? Do you just want to recover the nuggets or do you think there is good fine gold that you will also want to capture?
Huge California Nugget A Hoax
Sanders claimed he used ground-penetrating radar to survey his private property in Nevada County, California, and uncovered the chunk of gold with a backhoe when he was following up on one of the anomalies found by the radar.
Prospecting After Winter Storms
So, how much rain does it take to cause a major movement of gravels in a stream and redistribute the gold? The technical answer is enough water to move the bed load of the river.
Following Clues to a Hidden Gold Deposit
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Gold Placers of Southern California
I grew up in Southern California, and found my first nugget there, so I know my way around. Because there is good gold there, I thought it might be helpful to take a look at the many placer gold opportunities found in the southern part of the state.
