A former surface and underground W-Baryte mine located in the center of sec. 34, T.15S., R.4E. (protracted), a short distance east of San Luis village and wind mill and south of the Coyote Hole group. A small prospect, not described by Dale etal 1961; only approximately located. Produced 1939. Relocated and owned by M. Kyriak & Marshall Bartlett in 1937.

Mineralization is a vein deposit with an irregular coarsely-crystalline, grayish-white quartz and barite vein with scattered and spotty wolframite and scheelite cutting Cretaceous (?) andesite flows. The vein strikes N.60ºE. and dips 70ºNW at 6 to 10 inches (15 to 25 cm) wide.

Workings are comprised of an open cut and a shallow incline and are 30.48 meters long overall. An open cut is about 100 feet long and has a shallow incline. A small amount of hand-picked tungsten ore was produced in 1939-1940.

Description: Sandstone and conglomerate derived from volcanic rocks with associated intermediate-composition lava flows, breccias, and tuffs. In southern Arizona this unit includes rocks of the Artesa sequence, Pitoikam Formation, Mulberry Wash volcanics, Rudolfo Red Beds, Recreation Red Beds, and Gardner Canyon Formation. In western Arizona it includes the Harquar Formation, rocks of Slumgullion, and related(?) unnamed units in the Kofa and Middle Mountains. This unit is characterized by maroon, brown, and purplish-gray volcanic-lithic sandstone and siltstone, with subordinate to abundant conglomerate, quartz-rich sandstone and sparse limestone. (150-170 Ma)
