Small-Scale Hard Rock Production
December 2015 by StaffSo far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.
The problems of the submersible dredge tube are addressed by the subsurface dredge, where the enclosed sluice recovery tube is suspended from a flotation assembly...
With eight loads processed, a pumpkin-size rock fell into the hopper, stopping the whole operation until I could lift it out.
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.
Augers can be used effectively for placer exploration with certain limitations.
The biggest obstacle is that like many streams on the Kenai Peninsula, high water during the summer months from snow melt and rain can make dredging nearly impossible. The best dredging is in the colder months of the year.
