hi there,
just started prospecting
I have a mountain of this quartz on my property, with a gpx 5000 on factory setting, I receive a low-med single ,but with a high mineral setting ,no signal!
looks like rust spots and I think pyrite.
I crushed a piece and paned , lots of fine gold looking spots under 10x not sure if gold
would it be worth crushing a wheelbarrow load to find out if any gold in this quartz
cheers
Paul
