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.
California State and US National Panning Championships
Over 200 panners competed in this two-day event to decide who was the best of the best.
The Unusual Forest Nugget Patch
This is the story of a nugget patch I’ve been working on that is a bit unusual. I won’t be telling you where it is located, but I will tell you how I found it and how I’ve worked it.
Replacing Your 12-Volt Pump
In the “toolbox” of most every prospector there are certain tools that we tend to use consistently for a variety of reasons. Have you ever noticed that tools and equipment tend to wear out, rust and fall apart whether we use them or not?
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
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.
A Golden Summer
His take of gold was pretty close to what mine was—about a quarter of an ounce. We had just gleaned about half an ounce of gold in just twenty minutes.
Successful Detecting Requires Attention to Detail—Part I
So much of gold detecting depends on attention to detail. Every gold area offers its own distinct geological markers and as prospectors we must pick up on those markers.
