Started in 1954. Comprised of at least the Boso lease and the Nuhn lease. The latter was the location of the first economic uranium mining in Texas.

Excerpts from: "Geology of the Oxidized Uranium Ore Deposits of the Tordilla Hill-Deweesville Area, Karnes County Texas; A Study of a District Before Mining" - Geological Survey Professional Paper 765 - by C.M. Bunker and J.A. Mackallor

(page 1) - In the fall of 1954, uranium was discovered about 2 miles northeast of Tordilla Hill, western Karnes County, Texas by G.H. Strodtman, of Jafee-Martin and Associates of San Antonio, while he was making an airborne radioactive survey for oil structures. At about the same time, uranium minerals were found at the foot of the northern most point of Tordilla Hill (Hackney deposit) by Carroll Ewers of San Antonio, who was prospecting with a hand-portable counter.

(Page 24) - The Hackney (Bose) deposit at the foot of Tordilla Hill was one of the first deposits of uranium minerals to be discovered in the southeastern Texas coastal plain. The mineral lease of part of the Hackney tract, including the uranium deposit, was acquired by the late Dr. Fred M. Boso of San Antonio, shortly after the discovery of uranium mineralization there (1954).
