Prospecting on the North Yuba
December 2011 by Don RobinsonThe research I did for “Gold in the Slate Creek Basin” (September 2011 issue) found me chasing a channel out of the LaPorte territory headed towards the old mining town of Brandy City, California.
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
There are many smaller old hard rock mines out there—more than you might think. There are some small hard rock properties that are even open to be claimed if one does the right amount of research to find them.
One of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
I had some success following this premise this summer, finding a few nuggets in places I think I overlooked in the past.
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
Maybe we could find a few pieces of ore from that tunnel? It was worth a try. The old timers didn’t have that stamp mill for looks, so we set off to get some samples.
The biggest nugget I have found detecting here was three grams and the following weekend someone found a 9-gram nugget while detecting. Some have even found quarter-ounce nuggets, with one being a chevron nugget.
