Locality type:


A columbite occurrence/prospect located about 2 miles SW of the Rare Earth Mine.

Mineralization is 2 small, poorly exposed pegmatites.

About two miles southwest of the Rare Earth mine, two small poorly exposed pegmatites have been prospected by means of several shallow pits (Columbite prospect). The dikes are indistinctly zoned, containing small quartzose core pods. From the northern of these, several hundred pounds of columbite reportedly have been obtained. A few beryl crystals occur in the southern dike. Small vugs with yellow sericite masses also are present. The dumps at one deposit contain specimens with allanite blades several inches long, associated with minor amounts of monazite, which forms anhedral grains 0.2 inches long in quartz pods. The other dike contains a few crystals of reddish xenotime as much as an inch across (checked optically and by means of X-rays).


Workings include several shallow prospect pits. Limited production of several hundred pounds of columbite.
