Structure: Fractured Limestone Along Porphyry Contact And North Trending Shear Zone.

Alteration: Limestone Replaced By Silica, Epidote And Garnet.

Deposit: Deposits occur along the porphyry-limestone contact trending due east, and within a north trending silicified shear zone located in the eastern part of the claim group. Shear zone mineralization is about 12 ft. Wide and alteration about 50 ft. Wide. Oxidized ores give way to sulfides at about 20 ft. Depth. Limestone is fractured for a distance of 100 ft. North of the porphyry contact and mineralization occurs along the contact for a distance of about 3000 ft. 3 unpatented claims covering about 60 acres. Discovery year: 1880's

Geology: For regional geology see sierra cuchillo district.

Rock formation(s): Magdalena Group


Ore(s): Replacement, Fracture Filling And Shear Zone Mineralization
