Prospecting and Mining Old Mine Sites
December 2016 by Alex DolbeareIn 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.
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.
Nuggets make for the best memories and this patch was just adding to mine. In the hours of daylight I had left, I worked from that nugget to the bottom of the patch, collecting eight more nuggets.
Mike and I each selected a side of the creek and started to work our way upstream. We both worked the water and sides of the creek, and better than half the gold found in this area is in the water.
Some gems can potentially poison you, make you sterile and even make you forget who you are.
I opted for the underwater portion of the river. All I have to do is float down the river and pick large flakes and small nuggets out of cracks and crevices while staying cool in the summer heat.
Several areas came to mind, but each was eliminated for one reason or another. One that seemed to be hanging on was the old historic mining town called Placerville.
