Gold in Guyana—Part II: Process Optimization at Sacre Coeur Minerals' Lower Puruni Alluvial Mining Project
August 2012 by Carl BrinkIn Part Two of my two-part series I describe the mechanized alluvial gold mining operation on the lower Puruni River launched by Sacre Coeur Minerals in 2011.
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.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
Critical minerals are products that the government has designated as critical to our national interest because of both their potential military and industrial applications.
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.
Over the last several months, starting from before I left for Australia, I’ve been working on getting all the 2011 paperwork done for my mining claims. I will admit that some parts of the paperwork I let go until only a week or two before the due date.
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.
