AML Project: Inventory and Characterization of Inactive/abandoned mine (AML) features in New Mexico

The NMBGMR has been examining the environmental effects of mine waste rock piles throughout New Mexico since the early 1990s. There are tens of thousands of inactive or abandoned mine features in 273 mining districts in New Mexico (including coal, uranium, metals, and industrial minerals districts), however many of them have not been inventoried or prioritized for reclamation. The New Mexico Abandoned Mine Lands Bureau of the New Mexico Energy, Minerals and Natural Resources Department estimates that there are more than 15,000 abandoned mine features in the state. The U.S. Bureau of Land Management recently estimated that more than 10,000 mine features are on BLM lands in New Mexico and only 705 sites have been reclaimed. The New Mexico Bureau of Geology and Mineral Resources has collected published and unpublished data on the districts, mines, deposits, occurrences, and mills since it was created in 1927 and is slowly converting historical data into a relational database, the New Mexico Mines Database. More than 8,000 mines are recorded in the New Mexico Mines Database and more than 7,000 are inactive or abandoned. These mines often include two or more actual mine features.

Apache Mesa Rare Earth Elements Deposits

The Point Lookout Sandstone on the Jicarilla Apache Reservation in Rio Arriba County contains geological layers called “beach placer deposits”. Beach-placer sandstone deposits are accumulations of dense minerals that form on beaches, or in shallow ocean water. They form by mechanical settling of heavy minerals by the action of waves, currents, and winds. These deposits contain Rare Earth Elements (REE) which are important commodities required to manufacture green technologies, like wind turbines and hybrid/electric cars and are essential in most of our electronic devices, like cell phones and laptop computers.

Coal Resources

For 35 years the bureau has worked cooperatively with the U.S. Geological Survey to contribute to the National Coal Resource Data System (NCRDS). The goal has been to get stratigraphic and coal quality data for all of the coal-bearing regions of New Mexico into a national database.

Dating the Sands of Time

A new dating method, being developed at the NMBG&MR, uses our state-of-the-art geochronology laboratory, funded by NSF and NM Tech, to determine the age of detrital sanidine (tiny volcanic minerals) from sediments.

Development of 3D Aquifer Maps

It is surprising that New Mexico does not have a detailed map of all of the productive and accessible aquifers across the state. In a state with as little as 0.24% of our land surface covered with water (the least in the country!), having detailed maps of our groundwater resources and aquifers, is essential. Some of our neighboring states, like Texas and Colorado, have these maps already available, and are successfully being used to administer and conserve water. We have started a new multi-year project to develop 3D maps of aquifers.
