Hello everyone! I'm new here and new to gold mining, so please forgive if I'm ignorant on some things or most likely, lots of things....
I have a really good friend from there and he has a cousin that's been mining for 45 years. So me and my buddy are going to give it a go.
Over burden is anywhere from 6' to 12', shale streak is roughly 3' to 6' thick. Some nuggets, most mostly smaller stuff and lots of fines. Shale has a few larger rocks, some smaller ones, but is mostly made up of pebbles & sand.
Going to be using a 2 pump set up to start. One for pressurized water to blast the shale and another to suck it up for the sluice. Pumps are a 6" and both will have 100 hp diesels on them.
Typical sluice box is 6' wide and 25' long or so. They use carpet and expended metal on top with a riffle every 3' to 4'. Nuggets have been found all the way at the bottom of the sluice..... so you know they lost many out the bottom. Loss rates are 40% to 50%, so looking to cut that drastically.
Looking for any suggestions and inputs, especially on sluice design.
Thanks
