Union Uranium Company stock certificate 1954 (Colorado)

CO and UT mining certificate. Plain certificate hand signed by the president T. O. Matkins, Issued and not cancelled. Dated 1954. Approximately 11 x 8.5 inches.

Union Uranium Company was incorporated in 1954 to buy uranium claims and mining assets in Colorado in the midst of the Colorado uranium craze of the 50s.

In 1956, Union Uranium Company president T. O. Matkins reported that his firm has acquired half interest in 131 mining claims in Washington County, Utah. The company also purchased the Slick Rock Mine in San Miguel County, Colorado. Assets were believed to be sold to the Union Carbide and Western Gold and Uranium companies.

Washington County, Utah, has a history of uranium mining, primarily in the Silver Reef (Harrisburg) district, where uranium was found alongside silver and other minerals. Exploration increased in the 1950s, but the most significant commercial uranium deposits found were relatively small. The mines are no longer active.

The Slick Rock mining district (CO), whose principal producing area was known originally as the McIntyre district, was one of the first in the Colorado Plateau region to attract attention for its deposits of uranium, vanadium, and radium. Mining began again in 1949 for the major production of uranium, with vanadium as a byproduct. This period lasted until 1983 and ended when the price of uranium went into serious decline. Renewed interest in demand for uranium is reviving mining in the district.
