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.
Oscar Espinoza considers himself an amateur gold prospector, but the gold nugget he recently found puts many seasoned prospectors to shame.
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...
...day one was like watching the Gold Rush television show. He furiously worked the nozzle in an up and down fashion that resembled Jack Hoffman sitting on a backhoe.
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
I am learning more about gold deposition in this area than I knew previously. I am passing this information on with the hope that many of you will be able to locate patches and lines a little easier in the future because of this article.
Easing around the bedrock ledges and rock hopping, Terry and I came out into the open and were looking at a nice run of bedrock.
