Prospecting After Winter Storms
June 2017 by Don Robinson
So, how much rain does it take to cause a major movement of gravels in a stream and redistribute the gold? The technical answer is enough water to move the bed load of the river.
I worked my way to a flat area along a ridge where I could see a quartz blowout. As I got within 100 feet of it, I started seeing rock that I knew to be associated with gold.
Can a metal detector be used to find limonitic gossan material?
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
The 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.
A while back I was given a very special opportunity to take my metal detector to one of the most famous gold mines in all of California, the Original Sixteen to One mine in Alleghany.
