Prospecting & Detecting
An Interview with Minelab Engineer Mark Lawrie
January 2018 by Chris Ralph
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.
Find of a Lifetime
My metal detecting hobby began about ten years ago when I bought a used metal detector for about $300. I got it specifically to look for meteorites. It was pretty much worthless, not user friendly, and I did not find anything with it.
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.
Buyer Beware! Counterfeit Metal Detectors
When I was recently in West Africa, I got to see and play with my first, phony, Chinese knock-off metal detector.
Falcon Fanatic: Journey of a Novice Detectorist
My first day using my pinpointer I detected an area where the fellas’ big guns had swooped in and cleaned up all the “big gold” and I got over sixty tiny pieces of gold.
Getting Started
He excitedly told me he was going mining and wanted to know where he should go, how to do it, and so on. After he calmed down, I got excited. “I need to go!” was my response.
Detecting Clay Seams
Because the old timers were so good at locating the better paying deposits—most of them along clay seams in this particular area—it makes good sense to try and locate these clay lines at old mining sites.
Gold Geochemistry: Where Does Gold Come From?
Prospectors often wonder why gold deposits in veins like it does. Why is one vein rich while another is barren, even though they are only a few hundred feet apart?
