Small Mining Operations
Guinea Africa: Gold, Ebola, and a Monkey Barbecue
December 2014 by Bryon Tolle
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.
Gold in Guyana—Part I: Porknocking on the Puruni River Road
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.
Ophir—Possibly the Best Kept Secret in Alaska—Part II
I knew the nuggets got into the nugget patch somehow, I just had to figure out how and from what direction they came.
Moving The Big Rocks
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
Small-Scale Concentrating and Recovery Methods
The first step in my recovery process after milling the ore to the desired size is to table it. On this particular ore, I get good results milling it to minus 100 mesh.
Gary It's There
This year was a test. We had never done anything like this before, yet we grossed $30,000 in the short time we had to mine.
Spanish Gold Ledge Still Producing Gold
The Gold Eye placer claims, located in the La Cholla district of Arizona, are still producing some beautiful gold. From the days of the Spanish explorers and Mexican miners, men have tunneled into the earth in search of gold in this area.
Dry Washer, Wet System or Metal Detector?
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
