Trommels come in two basic sections. The first section is called the scrubber unit. The second is the punch plate, where the gravels and ore of a specified size drop out into a variety of sluice box recovery units.
Our testing over the past 15 years was to confirm or deny the USGS report completed in 1978. Besides the half acre test dig, we completed many additional test digs by hand and with the backhoe.
One of his friends had 700 feet of small-gauge mine track and a hundred-year-old track bender laying out in his back 40; plus he also wanted to join the team. Perfect.
I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.
