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.
Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
A Great Day On The Feather River
Mike and Machael dug in just downriver of that boulder pile and right away found good color and a few small pickers.
Cold Alaskan Gold—Part I
Crowds may be great for football games or the Fourth of July, but not for prospecting. So, this summer, while thousands of gold seekers were heading to the coast of Alaska, I headed to a remote part of the Interior.
A New Prospecting Spot
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.
Prospecting for Diamonds
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
Beach Mining for Placer Gold
What I saw was a beach area that was just completely covered in black sand. Rubbing my hands close together like a kid in a candy store, I could not wait to get set up.
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.
