Using Countercurrent Material Flow to Improve Gold Recovery Efficiency
December 2020 by Keith Bowen
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...

How many more clays seams lie adjacent to known shear zones and quartz veins in the pocket areas of southwestern Oregon?
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
I had a chance to visit the operation in person and talk with Neal. I was very impressed and I think our readers could learn a lot about building up a commercial placer operation from scratch…
A week later, a small team of us hit it again, and this time the gold really showed up.
