Border Silver
January 2003 by Edgar B. Heylmun, PhD
There is a sizable area that straddles the U.S.-Mexico border where native silver occurs in shear zones at relatively shallow depths. The district is in the low but rugged Pajarito Mountains, the highest point of which is 5,838 feet at Cerro Ruido, on the Mexican side. The deceptively rough terrain forced the first border surveyors, in 1855, to kill several mules and horses because of their injuries.Ask the Experts

One of the first pieces of prospecting equipment I acquired was a really nice little aluminum backpack sluice. I’ve used it for some time now and have always been impressed with how well it works for keeping the fine wire gold. But ever since I got on the Internet and started looking around for prospecting stuff, I have been toying with the idea of making a flexible conduit sluice.

The Miner’s Switchback
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
