Description: Rare earth elements (REE) are increasingly becoming more important in our technological society and are used in many of our electronic devices. REE include the 15 lanthanide elements (atomic number 57-71), yttrium (Y, atomic number 39), and scandium (Sc; Table 1) and are commonly divided into two chemical groups, the light REE (La through Eu) and the heavy REE (Gd through Lu and Y). REE are lithophile elements (or elements enriched in the crust) that have similar physical and chemical properties (Table 1), and, therefore, occur together in nature.

Description: This database includes available data, published and unpublished, on the uranium mills located in New Mexico. Throughout a period of nearly three decades (1951-1980), the Grants district in northwestern New Mexico yielded more uranium than any other district in the United States and milling that production in the state was important. The Bluewater mill was the first uranium mill built in New Mexico in 1953 by Anaconda at Bluewater, west of Grants, to process ores from the Jackpile mine at Laguna; that mill closed in 1982. Since then six additional mills were built, operated, and closed (Shiprock, Homestake, Ambrosia Lake, Church Rock, Phillips, L-Bar) and one additional mill (Marquez) was built but never operated. There are no active uranium mills in New Mexico at the present time. For more information on uranium mills see http://nmgs.nmt.edu/publications/guidebooks/downloads/54/54_p0165_p0177.pdf http://geoinfo.nmt.edu/staff/mclemore/projects/uranium/documents/mclemore13.pdf http://geoinfo.nmt.edu/publications/openfile/downloads/100-199/183/ofr_183.pdf
Description: This database provides information on the major uranium deposits in New Mexico that have been mined in the past or are known to contain significant uranium resources that can be mined sometime in the future, as of 2015. A major uranium deposit is a deposit that contains more than 80,000 pounds of uranium and includes past production plus identified or estimated resources. Information presented are the best data available and were obtained from published and unpublished sources (NMBGMR file data). Some of the resource and 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. Other resource/reserve data do conform to NI 3-101 requirements and are specifically referenced as such. Most of these deposits are in the Grants uranium district, which extends from east of Laguna to west of Gallup in the San Juan Basin. The Grants district is probably 7th in total world production behind East Germany, Athabasca Basin in Canada, Australia, South Africa, Russia, and Kazakhstan. Sandstone uranium deposits account for the majority of the uranium production from the Grants district and the most significant deposits are those in the Morrison Formation, specifically the Westwater Canyon Member, where more than 169,500 short tons of U3O8 were produced from 1950 to 2002. More than 100 major mines and undeveloped deposits are found in eight subdistricts in the Grants district, but only four projects offer the potential to produce in the near-term: Roca Honda, Mount Taylor, La Jara Mesa, and Church Rock Section 8. Although deposits currently producing elsewhere in the world tend to be higher grade and/or larger tonnage, the Grants district still contains a large enough resource to have a major impact on the global uranium supply in the future. This database includes most of those deposits. The economic feasibility of mining a number of these deposits will increase with the licensing and construction of a regional mill, improved in situ recovery technologies, decreasing production costs, and an increase in world-wide uranium consumption and price of uranium. For the purpose of this compilation, an occurrence is defined as (1) any locality where uranium or thorium mineralization or minerals are reported to occur or produced; (2) where uranium or thorium concentration exceeds 0.001%; or (3) where radioactivity is twice the background radioactivity. Any locality that has been developed, but not produced is considered a prospect. A deposit is any delineated ore body of economic size at a given time. A uranium mine is any locality that has produced uranium.

Description: This database includes uranium and thorium occurrences in New Mexico that have not been mined for uranium or thorium, as of 2015. Uranium and thorium in New Mexico are found in rocks all ages and lithologies, from Proterozoic granites to Recent travertine deposits in all but two counties in New Mexico. They occur in sandstones, coals, limestones, shales, igneous and metamorphic rocks, pegmatites, veins, volcanic rocks, and breccia pipes. For the purpose of this compilation, an occurrence is defined as (1) any locality where uranium or thorium mineralization or minerals are reported to occur or produced; (2) where uranium or thorium concentration exceeds 0.001%; or (3) where radioactivity is twice the background radioactivity. Any locality that has been developed, but not produced is considered a prospect. A deposit is any delineated ore body of economic size at a given time. A uranium mine is any locality that has produced uranium or thorium. The most important deposits in the state are within sandstones of the Morrison Formation (Jurassic) in the Grants district.

Description: This database includes occurrences of asbestos minerals found in mining districts in New Mexico that have been reported in the literature or in unpublished reports and field notes at the New Mexico Bureau of Geology and Mineral Resources, as of 2015. Any economic potential or health risk associated with these occurrences is not implied and each area must be examined by a qualified geologist. Asbestos is a mineral group that consists of six different silicate minerals that can be fibrous in crystalline form. OSHA defines asbestos fiber as any particle that is 5 microns or longer, with a length-to-width ratio of 3 to 1 or longer. Asbestos minerals can be found in bundles of fibers, which can be separated from the host matrix. The fibers have high tensile strength. The aspect ratios range from 20 to 100. The fibers are flexible and can be spun. Asbestos minerals are found in a variety of mineral deposits and can pose a health risk, specifically asbestosis, lung cancer, and mesothemlioma. In New Mexico, asbestos minerals are found in small amounts in some limestones adjacent to Laramide Cu and Pb-Zn skarn deposits, Laramide (polymetallic) vein deposits, Mo-W-Be contact metasomatic deposits, and porphyry copper deposits. Asbestos minerals are found in serpentinized ultramafic and mafic rocks in some Proterozoic terranes in New Mexico and can be associated with talc deposits. The amount of asbestos is so small in these areas in New Mexico that it is unlikely that significant quantities of asbestos minerals would be found in any alluvial deposits adjacent to these areas. There has been no eported production of asbestos minerals from New Mexico. However, nonfibrous ricolite (a form of serpentine) has been produced from the Ricolite district in the Redrock area (Ricolite district) of the Burro Mountains for carving, decorative, and dimension stone. Fibrous ricolite also is found in the Redrock area. The amount of asbestos is so small in these areas that it is unlikely that any health risk exists for residents and visitors in these areas. However, workers and others that could be exposed to dust in these areas that could contain asbestos minerals should have the dust examined for potential asbestos minerals and, if present, follow appropriate protection recommendations.
