Mineralization is a Gypsum deposit with ore in irregular and lens-shaped bodies hosted in shale and limestone above the Naco Group .
Large resources of high-grade gypsum occur here. There are 3 zones: zone 1 is 20-30 feet thick; zone 2 is 275 feet below zone 1, and, is 50-60 feet thick; and, zone 3 is 395 feet below the middle bed and is about 15 feet thick. Difficult access and steep dip limit exploitation possibilities.
