Prospecting With a Detector: Lessons Learned
November 2012 by Fred MasonThat is the course and intention for this article—to wander through some of the lessons I have learned in my thirty-two years of metal detecting and prospecting.
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
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.
While the bullion value of the nugget is already substantial, the size and rarity of the Ausrox Nugget combine to make its worth invaluable in the collector market.
We all continued over to another location at the top of a massive placer operation. Arriving at the draw, I showed everyone where gold had been found before and we all began detecting.
The first requirement is permission from a land owner. This can be tricky and it’s always a bit nerve-racking to approach a stranger cold with such a request.
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.
