Gold in Guyana—Part I: Porknocking on the Puruni River Road
July 2012 by Carl BrinkIn 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.
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
When I started dredging a short distance downstream from that feature I realized that I was into a major paystreak and much of the gold was coming right out of the upper gravel. I could see the chunky pieces falling out of the gravel as they were pulled into...
There are currently about 170 commercial-scale placer operations in Alaska. Most of these are small operations with just a few people working; they are often family affairs that operate seasonally only during favorable weather.
They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
There are currently three controlling agencies or entities over suction dredging in California—and you can make that four if the state legislature decides to further muddy the waters with additional legislation to block suction gold dredging in the state.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
Familiarizing oneself with an unfamiliar part of the country is often a requirement of successful gold prospecting. In the pursuit of gold, it may become necessary for a prospector to branch out into new hunting grounds.
