California Mineral Production Reports and Data

Annual Reports of Non-Fuel Mineral Production (2001‑2019)

The California Geological Survey publishes annual summaries of the state’s mineral resource production exclusive of oil, gas, coal, and geothermal energy. The most recent report covers the 2019 production year.

• 2019 California Non-Fuel Mineral Production

For 2019, California remained one of the largest producers of non-fuel minerals in the United States. This report discusses the commodities produced as well as trends in commodity production. This report is based on data reported by mine operators to the California Division of Mine Reclamation (DMR).

Historical Mineral Commodity Production Records and Data Dashboard (1958-1969)

This section offers access to part of our catalog of historical mineral commodity production records. The records provide detailed annual production data by county. We scanned these records to PDF from original typed and handwritten paper documents created by the California Division of Mines and Geology during the middle of the 20th century. To see these data visualized as a map and graphs, visit our California Historical Mineral Production interactive data dashboard. To download the scanned records, proceed to the "Downloading the scanned records" section below.

Notes

We've bundled the scanned records into .zip file packages, and grouped them two ways to accommodate different needs:

• By Year, All Commodities: 12 packages. Package sizes range from 359 megabytes to 818 megabytes.
• By Commodity, All Years: 66 packages. Package sizes range from 1 megabyte to 852 megabytes.

  Most of the records fall into two major categories: "Production" [data], and "Mailing list" (examples are shown in the adjacent images).

  

  

  Many of the Production records show not only commodities produced, but also commodities sold or used; consumed; or shipped. There are some records of ores received (by smelters). For simplicity we categorized them all as Production records.

  Other useful information you'll find in the scanned records include producer name, producer location, and mine name (these information are not included in the data dashboard).

  There are also a few "Mailing memo" and "Production memo" records that are exactly what the names imply. They don't offer statistical value, but we included them nonetheless.

  The records available here represent a fraction of the entire paper collection. We intend to scan and catalog additional records in the future.
