Prospecting & Detecting
Old Mine Sites and New Technology
September 2018 by Jack Geck
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
The Heavy Minerals in Your Concentrates
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
2015 World Gold Panning Championships
Every Spanish village seems to hold their pride in one unique area of expertise. Pamplona has its bulls, Barcelona its architecture, and gold panning belongs to Navelgas.
Carr Fire Gold
After burning more than 350 square miles, the Carr Fire near Redding, California, was finally out. Luckily our home was spared, and I had the opportunity to go metal detecting in burned areas previously too overgrown to access.
Feather River Gold
I didn’t think too much of our dredge hole and we were both considering a move when we hit bedrock. There was a good quantity of flakes and fines, but no nuggets.
Drywashing in Black Canyon, Arizona
May 2016After the hike and a quick snack break we gathered a few buckets of material to really dial in the drywasher for the most efficient recovery. This involves leveling the unit, setting the riffle box drop angle and regulating the speed in which the material is processed.
The Winning Hand
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
The Art of Underwater Nugget Shooting
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
