Small Mining Operations
Gold in Guyana—Part I: Porknocking on the Puruni River Road
July 2012 by Carl Brink
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.
Guinea Africa: Gold, Ebola, and a Monkey Barbecue
With great relief, the equipment I chose worked well, and after shoving into three days what should have been ten days of set-up and testing, we were up and running.
Persistence Leads to Over a Pound of Gold
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.
Resurrecting An Old Hard Rock Mine
There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.

If there is misleading wording anywhere, it will be in the sample data and in reserve/resource estimates.
A Third Generation Small-Scale Hardrock Revival
One of his friends had 700 feet of small-gauge mine track and a hundred-year-old track bender laying out in his back 40; plus he also wanted to join the team. Perfect.
Gold in Tertiary Gravels
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
High Sulfidation Epithermal Deposits
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.
