the copper peacock is a regular where i'm mining, the galena I've seen a thousand times just never found on my own till now, the magnesium I see quite regularly also ,, seeing it in crystalline form and in a sulfide form also seem to have found it infused into Granite flow.. witch is the hardest rock I've ever found..the White Talc also known as Sclerosol is common in formations with Copper magnesium, iron pyrite, gold, and rhodium.
The Quartz with the copper peacock (ie copper pyrite or copper Iron Sulfite) forms on aggregate of bornite... Chances on that rock of gold 90% yet it may be in minuscule amounts.
