Capsule

Work History

Staked as Teta cl (YA5259) in Aug/76 by Urangesellschaft L, which explored with mapping in 1977 and hand trenching in 1978.

Capsule Geology

The claims cover a pseudoleucite tinguaite phase at the southern margin of the Cretaceous Tombstone syenite stock. The tinguaite is strongly sheared and partially recrystallized. Linear zones up to 9 m thick containing uraninite, pyrrhotite and minor purple fluorite and molybdenite parallel foliation in the tinguaite. Yellow uranium secondary minerals coat near-surface fractures.
A 9 by 12 m outcrop of sheared tinguaite on the claims assayed 630 ppm U, while specimens assayed up to 5% U3O8. Olade and Goodfellow reported a background range of 1 to 282 ppm Th and 3 to 86 ppm U in the syenite and 55 to 125 ppm Th and 3 to 206 ppm U in the tinguaite.
