Uraninite with bornite inclusion, Blue Lizard Mine, Red Canyon District, Utah, USA

15”x15” Circular Uranotype from uranium autoradiogram

Unique uranotype available.

The Blue Lizard Mine site was first recognized in the summer of 1898 by John Wetherill, when he identified uranium replacement in petrified wood. The site was first recorded by claim in 1943 by J. Wiley Redd, then owned by William B. Redd & the Shumway Brothers, Colorado (1974). The mine started producing in 1951 and was a major supplier of uranium through the 1970s, operated by Goode Mining and Exploration.

Uraninite in the mine is found as a replacement deposit hosted in Late Triassic siltstone and sandstone of the Shinarump Member, Chinle Formation. The ore body is tabular, with a thickness of 1.83 metres, a width of 24.38metres and a length of 36.58 metres. The depth-to-bottom is 21.34 metres and the depth-to-top is 3.66 metres. The ore is found in three forms: channel fil where it partly fills the interstices between quartz grains and fills fractures cutting trough the rock, uranium replacement in small wood fragments, plant remains and organic material & lithology. Secondary uranium minerals have formed on the walls of the underground workings. This sample has a beautiful bornite inclusion, which appears as a bulge interspersed with uraninite.
