California's Mother Lode Quartz Veins
May 2015 by Chris RalphThe actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
Only the richest ores could be worked and shipped off for processing at a profit. As a result, early mining in the southern part of the Humboldt Range was short-lived. In the 1880s, placers were discovered in Spring Valley and American Valley on the east side of the range...
In this case, signs of gold were found at the bottom of the alluvial and then traced in a triangle up the face of the mountain until they stopped—that is where the digging began.
Many locals are just waiting for California to allow dredging once more, especially with the current gold prices. There are still plenty of good opportunities for prospectors in this area, just as it has been for so many years.
