Mountain Goat Trommel
The Mountain Goat Trommel operates on a reverse helix, so your tailings fall out the bottom end of the spinning barrel, while your gold concentrate gets propelled up and out the other end. Don’t worry, there’s a nugget trap at the bottom of the trommel so you don’t lose those larger pieces of gold in the tailings!
The Mountain Goat Trommel is named such that it’s light, portable, and easy to carry up a mountain, and like a goat, it’ll eat just about anything.
The reverse-helix design was first thought up by Archimedes 2000 years ago, it helped the Chinese clean up twice as much gold as the 49ers, from their tailings no less!
The Mountain Goat Trommel system is entirely self-cleaning, eliminating the need for the breakdown and clean-up that sluice box equipment requires.
The main barrel has ¼” inch deep spiral rifles spaced ¾” inches apart. We recommend you screen your placer material ½” inch or less for maximum efficiency, even though you can get ¾” rocks through the barrel easily.
The Mountain Goat Trommel has adjustable legs, but we recommend the factory setting, which puts the front legs 1” inch longer than the back legs. Use Jet-Dry to avoid fine gold loss.
You can use the Mountain Goat Trommel in a large tray, tub, or in-stream. Use with about 5-gallons of water, which is recirculated by a 750 gallon per hour pump.
