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.
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
I figure there are a lot of new people out there who have the same question. I will try to give some answers that hopefully will give you more confidence in finding your own spots.
I began detecting at the bottom of the gully and started making my way upstream. About mid-way there was a nice, flat stretch for about ten feet.
When I teach people about finding gold, I often explain that it is helpful to think of any river or stream that carries gold as being something like a sluice box.
The names attached to these areas came about from many sources. Many are easy to see why the name was given while others had a more contrasting note to them.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
