A marble-limestone/dimension stone quarry (and apparent W prospect) located in the SE¼ sec. 11 & the NE¼ sec. 14, T18S, R15E, 15 miles SE of Sahuarita at the end of the Santa Rita Road. Operated 1972-1975, 1987, approximately 1995 - ?. Operated by Imerys Marble Inc., which is part of Imerys S.A., Paris, France, 1995(?) - ? (WW Besse, 2014). Operated by the Specialty Minerals Inc. (A Subsidiary Of Minerals Technologies Inc. Of Pfizer Minerals). Former operators include the Homestake Production Co. (1972-1975); and, Calcium Products of Arizona.. Owned by the Santa Rita Mining Co. Limestone Division

Mineralization is a contact metamorphism deposit of marmolized Paleozoic Escabrosa Limestone altered to marble. This is an extensive marble deposit of white marble. Marblized limestone is gently dipping, faulted and fractured, and 300 to 500 feet thick. There are zones in the marble that contain disseminated pyrite and other sulfides.

Workings include a quarry operation. Produces limestone for a lime plant.

The deposit was mined by the Homestake Production Co. for quicklime for copper flotation circuits from 1972-1975. In 1987, production was resumed by Calcium Products of Arizona. The product was ground calcium products. Drilling was done by Paul Lime Co. in 1961 and later by Anaconda Co. (during Cu exploration). Pfizer purchased the mine in 1991 and planned a $3 million exploration and development program.

Quarried for lime products. Crushing, sizing and bagging plant. Markets in Arizona and southwestern U.S.
