A mercury mine located at Study Butte (pronounced STOODY), 5 miles East of Terlingua.
Worked before 1940 until the late 1940's. Reopened 1970 - 1972 (Diamond Shamrock Corp.)
Structure: Asymmetric Terlingua Anticline
Alteration: Shale Baked Along Contact With Intrusive Syenite
Deposit: Cinnabar-pyrite-calcite-hydrocarbons fill fractures in syenite intrusive and shale. Mineralized fractures generally trend NE, locally E-W, and rarely NW, dip 60° to vertical, and are up to 1 in wide. Ore bodies extend up to 10 to 40 ft above the shale/syenite contact and are highest in grade in the baked shale in the contact zone.
Development: Explored 1970's by Diamond Shamrock Corp.; econ.com: in 1903 a 50 tpd and a 20 tpd Scott furnaces were installed. In 1930 a 30 tpd rotary furnace, formerly at the Mariposa mine, was installed. In 1944 ore was treated in 2 medium-sized furnaces. The mine had to be continuously pumped to avoid flooding.
Geology: Cret limestone and shale are out by n-W trending normal faults in addition to the minerals listed in the m data set, a hydrocarbon mineral is present.
Rock formation(s): Pen
Ore(s): Fractures In Syenite And Shale
