A former U-V occurrence/mine located in the NW¼ sec. 16 & in the SE¼NW¼ sec. 21, T36N, R29E, G&SRM, about 5.3 km SE of White Ash Peak. The USGS MRDS database stated accuracy for this location is 100 meters. NOTE: This MRDS file seemingly is a consolidated file for both Mine No. 1 & Mine No. 2, Mesa 2 (Mesa II), P-21. The mines are presented separately as sub-localities since each has an individually assigned MRDS file number.
Tyuyamunite and vanadium minerals occur in the Salt Wash member as bands and streaks filling interstices between sand grains and as diffusion bands
and halos. Ore body elongated parallel to paleostream depositional trend. Positioned on the SW limb of the Chuska Syncline. The beds strike N60NW and dip l½°NE. Local rocks include Oligocene to Paleocene[?] sedimentary rocks.
Workings include underground openings comprised of 2 main adits at 2,500 feet long. Connects with the Mesa 1¾ incline and Mesa 2½ Mines. Room and Pillar method mused to extract the ore.
Production was 274,128 tons of ore @0.23% U3O8, 1.00% V205 (1956-1967).
Analysis data results: 15.0% V2O5 maximum.

|Rupelian - Danian|

|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)
