[ Ссылка ] - filmed Dave McCracken discussing using the Le Trap clean up sluice at the first gold prospecting group outing of the 2015 mining season in Happy Camp, California. The Le Trap sluice was used after the high banker sluice boxes were cleaned out of their gold bearing gravels then classified and run through the Le Trap. Basically its take about 5 gallons of material and cuts it down to about a quart of material of high grade cons with all the gold in it. I also use the Le Trap on my 6" dredge on the river during dredge season. See more of the New 49ers gold prospecting club here: [ Ссылка ]
