A Great Day On The Feather River
August 2015 by Tom LeftwichMike and Machael dug in just downriver of that boulder pile and right away found good color and a few small pickers.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Last month, one of our readers requested an article regarding the possible use of Google Earth for prospecting research. It was a good idea, so here it is.
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
Watching for these areas is one of my primary targets during the winter. It doesn’t take but a few inches of the surface moving away to give a fantastic target response that you didn’t hear prior to the washing of the surface.
...more folks rolled in on Saturday morning and many were eager to venture out onto the Sleepy Bear property—all 415 acres—and try their luck at finding some gold.
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
