Prospecting & Detecting
Just One More Time
July 2016 by Don Robinson
We chose this particular area because an old channel had run here at one point and had been heavily worked on top of a mountain hilltop. Erosion patterns cut deeply on each side, leaving the channel exposed. The erosion cut sharply, dropping into ravines far below.
Nome Offshore Dredging Creates Challenges
The Alaska state government has been trying to keep up with and maybe even stay on top of the situation by studying the problems associated with rapid growth and how to solve them.
Drywashing Arizona Gold
His findings were not exaggerated—after running 82 buckets of gravels in two days we had a remarkable 27.8 grams of gold!
A Gold Mine on a Washington Beach?
Bela and Barbara Kovacs began prospecting for gold about seven years ago as a family orientated outdoors activity. A welder by trade and lured by the simple fact that beach sands can contain small bits of precious metals, Bela decided a few years ago to build a sand sucking contraption that can sift the shoreline for anything worth keeping.
Critical Minerals: Titanium
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
Using Geologic Publications to Discover Collecting Sites
I understand that a person without geological knowledge could be daunted reading a geological publication. You can pick out the good stuff from a geological publication without a lot of geological knowledge.
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
Entry-Level Metal Detectors for Gold Prospecting
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
