Structure: The Deposit Is At The Base Of The Osobb Near The Contact With The Underlying Cane Spring Limestone. A Diorite Stock Intrudes And Has Locally Pyrometasomatized The Can Spring About 1 Mile To The North
Alteration: Bleaching, Oxidation, Kaolinization
Deposit: Ore occurs As irregular masses and bands replacing dolomite beds. Orebodies localized along mineralized faults and shear zones a total of about 40,000 longs tons of ore averaging 60% Fe has been open pit mined from three orebodies which strike E- W and dip. 10-20 south. Following a magnetometer survey on the mccoy deposit the USBM carried out a trenching and drilling program in 1944. They drilled two holes to a total depth of 92 feet. Nbmg visited the site in 1981, took sample #670, results unknown. ; info.src : 1 pub lit
Deposit type: Skarn Fe
Development: Open pit mine. Usbm did drilling and trenching program in 1944. Site being staked for golfields in 1981, with blasting to south.
Geology: The iron ore occurs As irregular masses and bands replacing dolomite beds in the osobb formation. The orebodies appear to be localized along mineralized faults and shear zones that intersect nearby intrusive bodies of diorite. Magnetite outcrops can be traced for 5,000, however trenching proved the ore bodies to be discontinuous. The drilling outlined a small tabular orebody which feathers out in both grade and thickness at the edges (kral, 1947).
Rock formation(s): Cane Springs (Quartzite, Shales)
Osobb Formation(Dolomite)
Ore(s): Favorable Bed Capped By Impermeable Layer And Near Intrusive Body.
