The Seven Troughs Mining District
September 2016 by Chris RalphThe 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.
His brother’s friend showed him a vial of gold that originated from his family’s mine in Honduras. Within two weeks Ernie had flown to Honduras to get a first-hand tour of the historic mine and the primitive operation underway to recover the gold.
For this article, I am focusing on industrial production plants that can handle 10 cubic yards per hour or more and would be fed by a loader or other heavy equipment...
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
With great relief, the equipment I chose worked well, and after shoving into three days what should have been ten days of set-up and testing, we were up and running.
When it was all setup and running, you had everything coming off the dredge riffles into the boil box. At the hole section, some of the water got sucked down and pulled a lot of black sand and over heavies…
…the process remains much the same: Drill holes, load explosives, close up the holes, blast and muck out the resulting broken rock.
Since this position was the least desirable due to the hard physical labor, the bucking room was used as punishment. Do you have a mediocre worker? Bad attitude? Off to the bucking room!
