Bibliography: Bulletin 67, "Cassiterite." Tin is not at present produced in California; but during 1891-2, there was some production from a small deposit near Corona, in Riverside County, as tabulated below. Small quantities of stream tin have been found in some of the placer workings in northern California, but never in paying amounts. Early in the current year, two new occurrences have been noted in northern San Diego County. Crystals of cassiterite have been found there, associated with blue tourmaline crystals, amblygonite and beryl. No commercial quantity has been developed, only small pockets having been taken out, as yet; but the prospect is an interesting one.
