They worked their plan, bit by bit, and sure enough, after the blast, gold was detected… Over two pounds of beautiful crystalline gold was recovered in that stretch!
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.
Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.
There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.
Some ores—mostly those with a high free gold content—are very amenable to gravity concentration. Well oxidized ores containing coarse gold are usually best for non-cyanide processes. Ores with significant sulfide content may require the...
When we last heard from Ernie, he was still in Honduras and we were anxiously waiting to hear how the set up and training went at the mine. It got a bit complicated after that.
This project taught me that you don’t need to be Albert Einstein to apply a little science to your prospecting. I learned that most of the science related to suction dredging is actually common sense. All we need to do is take the time to apply it.
May 18, 2019, after 26 years, I had finally saved enough money. I bought my one-way ticket to Fairbanks, Alaska, and I started off by finding a new job…
