Loma Blanca mine, Shasta, California

The U.S. Bureau of Mines' Minerals Yearbook reported that Homer Fenn of Hazel Creek produced tremolite from the Loma Blanca mine in Shasta County, California, in 1946 and 1947, and named him among Shasta County's tremolite producers in 1948 without naming the mine.^1,2,3 For 1950 the yearbook said both that "sales of tremolite were reported by the Loma Blanca Mines, Inc." and that "there was no commercial production from this operation in 1950," adding that "in November 1950 the lease expired, and the property reverted to the owners."⁴ For 1951 it reported California production "at a standstill," and that the owners said "their mine is open to lease."⁵

The documents report this mine producing asbestos fiber for sale.⁴
