Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): 4 Ore Bodies On Paymaster No. 3 Claim - One Body Described Above; A Second Body Trended E-W, Was 50 Ft. Long, 2-30 Ft. Wide, and 2-7 Ft. Thick; A Third Body Trended E-W, Was 65 Ft. Long, 2-20 Ft. Wide, and Up To 7 Ft. Thick; the Last Body Has NW Trend, Was 30 Ft. Long, 12 Ft. Wide, and 6 Ft. Thick; Veins On the Valley View Claims (S. Side Skull Canyon) Had A N 60 Deg E Trend and 80 Deg N Dip

Comment (Geology): Copper Ore Bodies Occur In Limestone On N Side Skull Canyon, In Quartzite On S Side; Limestone Dips At Flat Angles To Ne; Fissure and Shear Zones Strike Ene and Dip Steeply N

Comment (Location): Claims Extend Southward From Skull Canyon On Both Sides

Comment (Production): Total Production Estimated At $70,000. 4 Cars of Cu-Au-Ag Ore Were Produced In 1906. Item 2 Was Hand-Sorted Ore. Item 8 Value $40,000. Item 9 By Henry Eidelman From Paymaster Workings.

Comment (Development): 17 Patented Claims, Most Work On Paymaster No. 3 Claim (N. Side Skull Canyon), Valley View Claim (S. Side Skull Canyon)

Comment (Deposit): 7-77 All References Show the Mine In Section 15 But the 7 M Sheet (Copper Mtn) Shows the Workings In Sec 22. The Point Location Is the Mine On the South Side of Skull Canyon. 7-77 Attitude & Dimensions On Record Sheet 080 Are For the B Like Deposit Discovered In 1952. Other Ore Bodies Follow Fr Or Bedding Planes In the Qtzite and Lmstone. These Deposits Generally Irregular Or Pipe-Like In Shape.
