Prospecting & Detecting
Is It Time for a Change? New Ways to Find More Gold
October 2017 by Chris Ralph
The old report I read indicated all they ever did was dig some trenches and take samples. It sounded to me like a good place to take my metal detector...
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.
I Finally Made It to Northern Nevada
After a while I got a very nice signal and out came a sweet kidney-shaped bit of gold weighing about three grams.
Swing and a Miss
A very good baseball hitter might get a hit roughly one time out of every three at-bats, but for prospectors often the results are much sparser and it may take many trips before the prospector hits a home run.
The Perfect Summer
Within the first 3 hours he and I had found pocket after pocket of gold and couldn't wait to tell Levi of our treasure.
Summertime Gold Panning
I have smaller pans for cleaning black sand concentrates, big pans for taking large samples, pans with corners for pouring out materials, and pans with lots of special riffles. This variation is why I have so many pans—they each have their specialty.
One Potato, Two Potato...
Normally the detector he was using would sound off with a definitive high-to-low tone when passed over a piece of gold, which distinguished the gold from the many high iron content "hot rocks," but this one was different...
Prospecting Underground: Use Caution
In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
