Prospecting & Detecting
Good Assays and Bad
January 2012 by Chris Ralph
The high prices for gold and silver are exciting and certainly have revolutionized the prospecting and mining scene. New interest in gold and silver mining is springing up from every corner, from individual prospectors armed with gold pans to exploration and mining companies working to set up multimillion dollar commercial operations producing hundreds of thousands of ounces per year. The idea of getting riches from rocks is one that motivates a lot of folks all over the globe.

An Interview with Minelab Engineer Mark Lawrie
The design of metal detectors well-suited for prospecting is an interesting process and not necessarily an easy one to achieve. It is a combination that blends the desires of what prospectors would like, the requirements of sales people and dealers, with the science and physics of what the electronics can achieve.
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
