The PIGMI—a DIY Crevice Tool
April 2017 by Tom LeftwichI’ve had great success using it to gather gold from crevices. I’d like to share the design with all of you gold miners reading this article and hope that you get as much satisfaction building and using it as I did.
I had some success following this premise this summer, finding a few nuggets in places I think I overlooked in the past.
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.
As I started walking down to the river one chilly morning, the mist was hanging over the calm portions of the water like a white cotton blanket. This scene got me to thinking about why the river was like that—the deep pools, boulder fields, gravel bars, the effects of how much water was moving at any given time along the watercourse—and most of all the relationship all these things have on where I will be able to find gold.
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
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.
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
