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.
The big moment finally arrived. With Norm suited up, I pulled the motor to life and felt instantly better. There’s really something relaxing about the sound of a dredge running—they don’t sound like anything else.
We needed something to cook on, so we brought most of our kitchen with us including our full-size oven, which was pretty funny to see in the middle of a rainforest. Food was always a concern, but fortunately for us...
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 burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
With every look at the box I was pulling out a few pickers and a nugget or two. The smile I had the previous night just got bigger and bigger throughout the day.
