Prospecting & Detecting
Highbanking for Gold
August 2018 by Chris Ralph
Pumps can be set up quite a distance away horizontally from the sluice, even hundreds of feet. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30 to 40 feet is the maximum vertical climb for most pumps.
Early Summer Mining in Wyoming
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.
Prospecting Australia—Part I
The call of gold is a strong one and it has pulled men from every corner of the planet. That said, I guess it’s now my turn to chase far away gold.
Prospecting for Silver Deposits
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
Endurance Is Golden
Feeling through the mud, I felt the weight and shape of what could only be gold. Throwing my hand in the water revealed a sixteen-gram nugget oozing with character.
Proper Assaying of Placer Samples
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
A Golden Summer
His take of gold was pretty close to what mine was—about a quarter of an ounce. We had just gleaned about half an ounce of gold in just twenty minutes.
Excavator Testing Wet Placer Ground
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
