Mineral Production in New Mexico
Mining and production records are generally poor, particularly for the earliest times, and many early records are conflicting. These production figures are the best data available and were obtained from published and unpublished sources (NMBGMR file data, cited references). However, production figures are subject to change as new data are obtained. Any resource or reserve data presented here are historical and are provided for information purposes only, and do not conform to Canadian National Instrument NI 43-101 requirements. Sources of metals production from New Mexico include: 1900-1986 from USGS and USBM Mineral Yearbooks, 1987-present from New Mexico Energy and Minerals Dept., USGS (1965), Lindgren et al. (1910), Anderson (1957), Howard (1967), North and McLemore (1986), McLemore (2001, 2017) and other cited references.
Historic and recent production and reserve/resource data are reported in metric or English units, according to the original publication, in order to avoid conversion errors.
NOTE: This page is an ongoing project and additional districts will be added as the tables are completed.

A mining district, as used by McLemore (2017), is a group of mines and/or mineral deposits that occur in a geographically defined area (such as a mining district or coal field) that locally are determined by geologic criteria (distribution of mines and deposits, mineralogy, faults, lithology, stratigraphic horizons, common mineralization processes, age, etc.) and has had some mineral production.
A prospect area is an area defined by geologic criteria (distribution of mines and deposits, mineralogy, faults, lithology, stratigraphic horizons, age, etc.) that has had no mineral production.

Statewide by Year
New Mexico (Cu, Au, Ag, Pb, Zn, U) (2/21/2021)
Note that most of the Mo production in NM has been from the Questa mine (closed in 2014), Santa Rita Copper mine, and sandstone uranium deposits in the Ambrosia Lake subdistrict.
