In California gold came in so many different geological formations men had to be clever to get it. I haven't heard of hydraulic mining much in other places in America but stamp mills to crush the ore were common all over where gold was mixed with rock and they usually went on 24 hours a day. The noise was terrible.

If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 -500 mV using NaHSO3 and your gold will precipitate.
