Enrichment of Mineral Deposits by Weathering—Part I
March 2016 by Chris Ralph
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.
How to Evaluate Mineral Claims—What to Know Before You Buy
Even though they have put down thousands of dollars, the buyers often stop paying on their claims part way through the process after they realize they’ve been duped, but the company just sells it again to another buyer.

…the process remains much the same: Drill holes, load explosives, close up the holes, blast and muck out the resulting broken rock.
A New Method for Handling Stubborn Gravity Middlings
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
Geobotany: Plants Associated With Mineral Deposits
Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings.
Cyanide-Free Gold Separation
Some ores—mostly those with a high free gold content—are very amenable to gravity concentration. Well oxidized ores containing coarse gold are usually best for non-cyanide processes. Ores with significant sulfide content may require the...
A Few Pointers About Cracks and Crevices
Because these crevices catch and hold gold so well, it's worthwhile to learn how they form, which ones are good for catching gold and which ones are not.
What Equipment Do I Need?
Getting started in prospecting often requires the purchase of some equipment, but one can spend as little as $10 and be finding gold or spend thousands and also be finding gold—yet you will probably have many more opportunities and possibilities with more and better equipment.
