Hard Rock University: Expensive Hobby or Real Business?
July 2015 by Keith BowenImproper sampling techniques lead to more avoidable heartache than almost anything else in micro mining.
Father’s Day in Australia was on September 2, and it’s a day a group of miners from “down under” won’t soon forget.
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
Gold in Guyana—Part II: Process Optimization at Sacre Coeur Minerals' Lower Puruni Alluvial Mining Project
In 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.
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 fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
I’d like to offer some practical comments about staking and maintaining mining claims. Owning your own claim is the dream of many prospectors. I’ve made good money off my mining claims, both from the minerals I have found on them as well as from leasing out some of my claims to larger mining and exploration companies.
