Potholes and Other Bedrock Traps
September 2012 by Jim HalloranPotholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
I furiously started pulling material out of the side wall and putting it in my scoop. It didn't take long to discover that the source of the scream was from a one-ounce chunk...
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
Normally we do not cover gem and mineral shows, but this one is a little different. The Tucson (Arizona) Gem and Mineral show is the sales source for so many small mining operations, I felt I had to address this show and its possibilities for the small miner.
I was amazed and surprised, and I took a moment to admire how beautiful this coarse chunk of gold was. It later weighed exactly one-half ounce.
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
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.
Anyone who has found a patch knows the difficulties involved. Those who haven’t can guess, and with any effort will soon realize it.
