A Break in the Weather

Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
Take a look at the picture—it’s pretty simple and you can build it yourself.
...we finally got back to this exploration effort. The old works there were up above the old camp, which was very significant in size.
The pit was a classic one—exposed shale bedrock with all the material being washed out one end of the pit. Within a few minutes I had a nice mellow signal that was in open ground.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
