Prospecting and Exploring for Gold Panning Sites

Prospector and burro, western Colorado, USA ci...Image via WikipediaProspecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their interest for gold is the most valuable tool for exploring new deposits.

Gold is a very widely disseminated throughout nature and may be found in any geological formation from the oldest rocks to the deposits that are still being formed, but in common with other metals, it is more likely to be found in the oldest rocks and in those places where the earth crust has undergone the most extensive changes such as elevations, folding, tilting, faults, fissuring and also volcanic action, with resulting changes in the composition and texture of the rocks.

The current technology is very important in development new project and exploration of new deposits begins with the selection of a target area. This is followed by reconnaissance exploration in which satellite remote sensing; geological mapping and seismic techniques are used. In turn, this is followed by detailed geophysical studies and later, a detailed drilling, sampling, assaying and mineralogical study. Gold deposits are sought with many techniques, but they are based on geochemical studies. Commonly more than one method is employed. With these methods, the geologist is looking for anomalies. Perhaps, the most important techniques are photogeology and seismic techniques.

Where Did the Gold Go?

The Quesnel gold pan.Image via WikipediaI had a really good entry all typed out  Ready to go and pressed transfer and it just disappeared.

It was all about gold and how it mysteriously disappears. You know what I mean you find a really good Creek. You do a little sampling and it come out good. Now your gold pan only holds a couple of shovelful's so if you can get that much gold in two shovelful's you better go back  and get your 5 gallon pails and fill them up.

Up in the morning and down to the creek, out with a shovel and fill the pails.  You classify it to a quarter  of an inch.

Luke where did you come from? You snuck in there all by yourself did you? You say you're going to pan this batch out? Great, get  at it.

One half an hour later...  how's it going with you Luke? You're ready for the final cleanup! Let's see what you've got. Lotta black sand in there that's a good sign I think. Give her the final swirl when can let's see what happens.

Excellent! As I was shoveling I was thinking this was cannot be another one of those where did the gold go? Expeditions. I'm sure glad you came along, you probably bought lock with you. Let's get that gold into the bottle. We can probably do a couple more  buckets before we leave. The water will be high next week and we will be able comeback to this exact spot so let's get as much done as we can now.
