78 GEOLOGY AND ORE DEPOSITS OF SIERRA CO., N. M.
FLUORINE AREA
The Fluorine area is at the northern boundary of the county and in Catron County, the post office of Fluorine being on the Beaverhead highway just north of the county line. The district includes the isolated block of limestone that crops out through the extrusive rocks in this area. The limestone and the sur- rounding igneous rocks are cut by abundant quartz veins and stringers, some of which carry moderate amounts of gold and a little silver, but the metals seem to be irregularly distributed. In 1931 and 1932 some development work was done in this district. No important shipments have been made. In the autumn of 1933 it was rumored that several of the properties had changed hands and that a renewed activity was pending. The Elephant group of claims is located in this area.
PHILLIPSBURG AREA
The principal mines in the Phillipsburg area include the Oc- cidental, Black Mountain (formerly called the Minnehaha), Great Republic and Keystone. Production from the Occidental and Black Mountain mines has been about $25,000, from the Great Republic about $25,000, from the Keystone $5,000 and
