Underground Mining: Stoping Methods
October 2016 by Chris RalphIn 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.
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
Everyone has a bucket list, and one of my items has always been to dredge and dive in a major river, Oregon’s Rogue, with the opportunity to find some chunky gold.
Some claim they can smell gold. This may be, but when I take a whiff of gold, I smell dirt, rotten eggs, garlic or just nothing: my nose is everything but sensitive.
I pulled out the nuggets I had worked on previously and looked at the size of the wire basket that the items to be cleaned are placed into. It looks much like a miniature french fry deep fryer.
The big moment finally arrived. With Norm suited up, I pulled the motor to life and felt instantly better. There’s really something relaxing about the sound of a dredge running—they don’t sound like anything else.
On my weekends off I spent many hours dredging the Second Broad River from Cane Creek Road up to the headwaters. I used a three-inch dredge with air and graduated to a five-inch with air.
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
