Economic geology of portions of Del Norte and Siskiyou counties, northwesternmost California

The mineral deposits discussed in this report were studied in connection with a program of research in the geology of the western Siskiyou Mountains carried out under the supervision of Professor J. P. Buwalda. Most of the deposits are not being exploited at present and many have not been worked in over a decade. Some occurrences have potential economic value, depending upon market and possible improvements in transportation. The study has been made, however, not from the standpoint of a mining engineer interested in future production, reserves, ownership, etc., but rather from the scientific aspect in regard to geological setting and genesis
