Prospecting for Pegmatites

Not long after this, I was camped out with the geologist beside the Similkameen River where he showed me the evidence that an ancient channel existed on our claim.
On my weekends off I spent many hours dredging the Second Broad River from Cane Creek Road up to the headwaters. I used a three-inch dredge with air and graduated to a five-inch with air.
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…
In this article, I am going to take a look at three Midwest states and go through some of the prime places for prospectors to find nice local gold there.
I didn’t follow-up on this opportunity at that time, as I already had as much on my plate as I could handle, but the potential for this property has never left my mind.
