A piece of quartz float I picked up near the barn that looked interesting. I busted it up with a single jack and ran though the jaw crusher and washed the crush. The fines off the crush contain some gold dust I still have the crushed material to run through the chain mill. The chain mill had problems hole in the screen and bolts coming loose sounded like end of days for the mill. Repaired with parts on hand and ordered new parts to hold the screen down. Not all lost look what was hiding under the damaged parts it will pay for the new parts. Happy Mining
