Claimed a mine

[Tesorodeoro]

I'm not sure it you saw but I posted links to very nearby mines above with production rates. I'm confused on their minerology. One ore is listed as argantite, which is the silver. The other lists granite as the host rock and the ore as "gold." Does that mean the granite contact a regular quartz vein that itself was the ore? I thought host rock meant that you were actually processing. Another mine lists quartz monzonite. This looks similar to granite, so is that what they were processing, or just the rocks that the actual quartz vein was in?

I’m not a hard rock expert. I would expect the ore was found in the contact zone with at least one side being granite. Likely there was gold in the quartz at some concentration, but many times the gangue? material located between the quartz and the granite might have a higher concentration of gold. Perhaps we might get an education if someone more educated should respond.

I talked to a buddy who’s been involved in a couple mines around there and he said it’s usually on the hanging wall between the quartz and granite so it sounds like you were right.

He also said there’s much higher grade than what is listed and mentioned a mine pulling out a golf ball size nugget a couple times a month. So fingers crossed…


Looking at a geology map, the adit is right at a junction of sedimentary, unconsolidated, and igneous (granodiorite), and heads towards the igneous. Interesting
