A W mine located on the SE side of Guajolote Flat.
Mineralization involves granitic rocks invaded by a stock or pipe of acid porphyry about 1,200 feet diameter. The southern border of this mass shows nearly vertical fracturing and local intense sericitic alteration.
A sericite zone about 5 feet wide contains irregular particals and masses, to several inches diameter, of a unknown brownish tungsten mineral. Adjacent wall rock also carries some particles of a similar tungsten mineral. Oxidized molybdenum compounds are abundant in this mineralized area.
