Small Mining Operations
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
Even though they have put down thousands of dollars, the buyers often stop paying on their claims part way through the process after they realize they’ve been duped, but the company just sells it again to another buyer.
At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
I believe dry washing is an underappreciated prospecting method. There are plenty of places where there is some pretty decent gold to be had, but the spot is a long way from any water and dry processing may well be the best way to go.
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.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
Q: How do I improve my small-scale mining operation’s gold production?
