Excerpt from California Journal of Mines and Geology, Vol. 35: Quarterly Chapter of State Mineralogist's Report XXXV; January 1939 The accompanying report has been prepared from data and Information gathered by the authors, who were assisted by field workers Of a wpa project which was sponsored by the board Of supervisors Of San Diego County. For twelve months during 1936 and 1937 they inspected and reported on 325 mining claims and quarries in the county. The information thus Obtained was entered on questionnaires which had been prepared by the Bureau Of Mines Of San Diego County. For data regarding mines that were flooded and impossible to enter at the time Of the survey, resort was made to former reports Of the State Division Of Mines, supplemented by information furnished by owners Of the properties. A final field check on Operating properties was made by the senior author late in 1938. Primarily, the main Objective Of this report is to indicate present and potential mining activities in San Diego County. Occasional reference has been made to events Of historic interest. For detailed information on the geological and physiographical features of the county, the reader is referred to exhaustive reports which have been previously published, mention of which is made later.
