I found the mines on my google earth map, that I was in when I was in Arizona.
It was a primary producer of gold.
This is the ore body layout.
Ore body information
General form LENSES, STRINGERS, MAINLY LENTICULAR
Strike N 60 E
Dip 80 S TO VERTICAL
Width 0.91M
Length 365.76M
This is the host rock info
Host and associated rocks
Host or associated Host
Rock type Metamorphic Rock> Schist
Rock unit name Pinal Schist
Rock description Pinal Schist
Stratigraphic age (youngest) Neoproterozoic

I was wondering what would be the best way to see if they left anything in there. It was supposed to be re-worked in 1981, but nothing happened there. Is there anything I should be looking for in the host rocks? The only way to get down there is via a quad or a side by side 4 wheeler vehicle. It's very rough terrain.

One thing I can say about old mines are... they are loaded with snakes. Man, I was digging in this huge deep pit to check for samples, moved back leaves to dig and bingo... snake eggs! About a dozen or so. Good thing they were not in the pit with me. Got out of pit fast. That was the smae mine we found a copperhead resting on a root under bank in creek. Old mines are extremily dangerous. Be careful. They are fun to explore.  |

Since the main collectors in your list are copper and lead, then you will need to look for the sulfides chalcopyrite and galena. Both are 100% indicators in a gold bearing area.
Lenses means the host rock isn't linear, rather it travels vertically, thus the vertical dip designation, pinches off and pools under the pinch, then breaks through to he next level above. These are the pinch pockets that hard rockers look for.
No matter how well worked it was, the gold associated with sulfides are in the 325 mesh and smaller range, and are overlooked by 99.99% of all gold processors.
There's good money to be made on leftovers by the enterprising 0.01% of companies who understand the math, and love very fine gold.
10 pounds of 325 mesh gold is worth as much as 10 pounds of 20 mesh gold, and there is a whole lot more of the former, and it is easier to find, and cheaper to find.
This vein is 3 feet wide and 1000+ feet deep. Start diggin'!

Sam That's just one side of the vein, there is a creek going between two mine shifts, and they both have different id's I will put the second mine up. I am gonna go dredge down in the creek, there is tons of black sand.. I dug a 4 foot hole.. and it was black sand. Could hold micro gold in it. I seen what 325 mesh look like, how hard is it to actually crush that rock on site haha.. just wondering, it's in a very remote area, closest town is 14 miles by quad. |

The other mine is just a "site" as they call it or a trench, but there is actually a shaft going into the hillside.

Hmmm... Sounds like the Tonto strike.

Different mine, same strike I bet. Tonto National Forest and the area in and around Spring Creek leading into Lake Roosevelt. Goooood stuff.

Yep that area is about right I was thinking of getting a keene bucket crusher and running the rock through a gold cube at different meshes. |
