Analytical data

Result SOME OF THE ORE FROM THESE WORKINGS CONTAINED AS MUCH AS 2% COPPER AND 5% LEAD, BUT MOST OF THE ORE NOW EXPOSED DOES NOT SHOW MUCH SULFIDE OTHER THAN PYRITE. THE GOLD CONTENT. EVEN IN SELECTED ORE, IS PROBABLY LESS THAN 0.05 OUNCE TO THE TON.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic
Deposit size Small
Significant No

Mining district

District name Reese River District

Land status

Ownership category Private

Comments on the production information

  • TOTAL VALUE PRODUCED WAS $5,000 TO $100,000 CUMMINGS MINES ORE THAT RANGED IN CONTENT FROM 300 TO 1500 OUNCES SILVER TO THE TON. THIS MUST HAVE BEEN CAREFULLY HAND-SORTED MATERIAL. CUMMINGS' PRODUCTION IS UNCERTAIN BUT DID NOT EXCEED A FEW THOUSAND DOLLARS.

Comments on the workings information

  • THE PORTAL OF THE CUMMINGS LEASE TUNNEL IS ON THIS CLAIM. THE TUNNEL FOLLOWS A QUARTZ VEIN FOR A DISTANCE OF 290FT IN TO THE HILL SIDE. THREE RAISES, ONE REACHING THE SURFACE, EXPLORE THE UPPER PART OF THE VEIN; AND WINZES WITH DRIFTS LEADING FROM THEM FOLLOW THE VEIN FOR A DISTANCE OF MORE THAN 100 FEET DOWNDIP BELOW THE TUNNEL LEVEL.

Comments on development

  • MUCH OF THE WORK WAS DONE BY CON CUMMINGS UNDER LEASE IN 1916.
