Gold in the San Francisco District Oatman, Mohave County, Arizona
December 2013 by W. Dan HauselI 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.
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
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.
The gold in this area can get quite large. Most of the pieces are about half a pennyweight on average.
As I planned for my trips, I concentrated on how to lighten my pack yet still carry enough gear to make the trip productive and enjoyable.
We decided to run a detector over each piece. If we got a decent signal we placed the piece into a high-grade pile and the rest went into another pile to be worked on later. This high-grade pile wasn’t that large—maybe 25 pounds...
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
