The Santobar mining district is in west-central Sanpete County about 6 mi west-northwest of Ephraim. There is little published information on the district and it is a minor Zn-Pb producer. Total district metal production at modern metal prices is estimated at $47,000. The only productive operation was the Santobar mine.
The Santobar district is within the Sanpete–Sevier Valleys section of the transition zone from the Basin and Range Province on the west to the Colorado Plateau on the east. Mineralization is associated with a N. 15° E.-trending, 70° SE.-dipping fault that places Cretaceous-Paleocene North Horn Formation against Paleocene Flagstaff Limestone. The ore occurs in a fault zone and in the Flagstaff Limestone. The primary ore/sulfide minerals are galena, pyrite, and presumably sphalerite (Pratt and Callaghan, 1970; Perry and McCarthy, 1977). There are no intrusive rocks in the district and the metalliferous fluids are likely the result of expulsion of connate fluids associated with the halotectonics of the Arapien Shale.
