Re: Jake: Have you ever been to Contrary Creek in VA. off rt.522??

In the past there was a mine upstream from the bridge. They had a
roasting facility along with stamp mills.  The foundation is still
there for the mills.  Pyrite from the stream assays 0.2 troy oz per
ton.  Now worth about $180.00/ton.  Take it home, roast it, mill it
and amalgamate with mercury.  Make an easy living!

A ton of this ore would be about one half a cubic yard or about
thirteen cubic feet more of less.
