An former underground U-V occurrence/mine located in the SE¼ sec. 21, T36N, R29E, G&SRM, 4.0 miles SE of White Ash Peak. NOTE: The geographic coordinates presented are taken from USGS MRDS database file #10112399.

Mineralization is tyuyamunite and carnotite in lenticular masses hosted in Late Jurassic mudstone and sandstone of the Salt Wash Member of Morrison Formation. The ore body is 1.22 meters thick. Ore bodies occur in units showing the most rapid variation in thickness in the Salt Wash member of the Morrison formation. Local rocks include Oligocene to Paleocene[?] sedimentary rocks.

Workings include underground openings comprised of a 30° incline that connects with the Mesa 2, P-21 Mine. The room and pillar method of extraction was employed.

Production was 44,174 tons of ore @ 0.20% U3O8; 0.89% V2O5 (1956-1958).

Resources largely depleted.

Rupelian - Danian
28.1 - 66 Ma



ID: 2778515
Oligocene to Paleocene[?] sedimentary rocks

Age: Paleogene (28.1 - 66 Ma)

Stratigraphic Name: Chuska Sandstone

Description: "Rim gravels". Light colored, weakly to moderately consolidated conglomerate and sandstone deposited largely or entirely before mid-Tertiary volcanism and extensional faulting. Most sediment was deposited by early Cenozoic streams that flowed northeastward onto the Colorado Plateau from areas to the southwest that are now lower in elevation than the Plateau. Sediments of this map unit, other than the Chuska Sandstone in northeasternmost Arizona, are commonly referred to as "rim gravels" because they now rest on or near the Mogollon Rim, which is the southwestern edge of the Colorado Plateau. (30-65 Ma)
