Hi,

I found a bag of rocks at our local salvation army, inside was a big hunk of peacock ore. I tested it with my gold testing kit and it keeps coming up positive for gold? The bag also had a few chunks of "fools gold" that tested negative for gold. I have been a "fool" in the past so I thought I would ask a few more questions,  does fools gold test positive for gold? If it is gold how do you get the gold out of the rock?  The whole bag of rocks only cost me $5. I do have a metal detector, just sometimes I have better luck at the salvation army.
Thanks for your help

Sherry

yes, gold can be associated with bornite (peacock ore), but I rather doubt if there is anywhere near enough recoverable gold to make it worth your effort to extract it from that small sample.   You'd be better off keeping the sample intact as a reminder for when you are in the field.

Or, for kicks and giggles you could spend the time crushing it and then pan it oh so carefully. To much work that tiny amount for me.

If this was a repeatable find, as in you found a seam of this rock that went for miles along the ground, then an assay to determine the gold content per ton would reveal if it was a viable and profitable seam of lode gold. Otherwise, as has been said here already, it's simply not a huge profit to remove it from its ore. Crushing gold in a stamping mill is the way that the gold is extracted. Sometimes the rock is boiled away using acid. Other times the gold is amalgamated with mercury and later the mercury is removed using a retort system. Both are dangerous to humans nearby so have to be done in controlled environments.

Because of the current prices of gold, formerly rejected ore seams are being reevaluated for profitability. In days gone by, an or that assayed at $3.00 per ton was rejected as being a non paying assay. Today, that same or contains $12.00 per ton or more making it very much a paying mine.

If you have access to a university, ask the geology department if they can tell you the source of your ore. They can normally narrow it down to a region which you can explore (called prospecting by many of us). Good luck!

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

I think a specific gravity test may be the best road to take with your sample. I would keep it as a sample rock as it would hold the most value  in this form to a collector also looks nice, good buy     Cool
