Prospecting & Detecting
Small-Scale Miners Rock the Mining World
August 2012 by Chris Ralph
With the high price of gold, there are many new prospectors out in the hills all over the United States, and while we would all prefer to be finding those larger nuggets, it doesn’t always work that way. Sometimes all that is available is nothing more than a few small flakes. The truth is, new prospectors are sprouting up all across the planet—especially in the developing nations.Endurance Is Golden
Feeling through the mud, I felt the weight and shape of what could only be gold. Throwing my hand in the water revealed a sixteen-gram nugget oozing with character.
Jim Madden's Gold

Silverton's Gold
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
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.
