A Third Generation Small-Scale Hardrock Revival
November 2019 by Ron Kliewer
One of his friends had 700 feet of small-gauge mine track and a hundred-year-old track bender laying out in his back 40; plus he also wanted to join the team. Perfect.
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
I decided to focus my attention on some exposed bedrock that was along a little stream only about 100 yards from our cabins. My very first pan full of gravel showed several nice small flakes that were just big enough to be picked up with my fingers. That first pan showed that indeed there was some very nice gold to be had here...
I probably swung over a few targets without noticing them. My first target came about ten minutes later as I went over a part of the high bench in this wide section of the dry wash.
On our fourth trip, we finally reached the top edge of the old hydraulic pit, and it was monstrous.
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.
