Hi guys,

Just to let everyone know, I processed 40 of the little rockwell and chips like them, about 1inch by 1inch, just pried them in half
and ran through hcl peroxide, then poor mans ar, got .25 grams from them.

Jim,

Sounds like a descent yield. Any losses experienced, or speculated, either in solution or handleing of the precipitant?

Thanks for Sharing results,

Nick

There is a small amount of gold powder left on the filter paper. I do not think it would have registered on my scale since it accuracy is only .005 grams.
