How To
Operation And Application Of Magnetometers
October 2014 by Chris Ralph
The technology used in these devices has advanced greatly in the last century. Many different types of physical effects are used to measure these magnetic fields and we will briefly look at some of these.
Hand Panning Micro-Fine Gold
Once you get down to the black sands or a few tablespoons of material, the technique changes dramatically.
What, Where and How for the New Prospector
How to go about the entire process of prospecting is a big question. The answer comes down to research and preparation.
Enrichment of Mineral Deposits by Weathering—Part I
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.Ask The Experts

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...
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.
The Basics of Geophysical Exploration
In developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...
