Mineral Resources Program

The USGS Mineral Resources Program (MRP) delivers unbiased science and information to increase understanding of ore formation, undiscovered mineral resource potential, production, consumption, and how minerals interact with the environment. MRP supports data collection and research on a wide variety of non-fuel mineral resources that are important to the Nation’s economic and national security.

Formation of orogenic gold deposits by progressive movement of a fault-fracture mesh through the upper crustal brittle-ductile transition zone

Orogenic gold deposits are comprised of complex quartz vein arrays that form as a result of fluid flow along transcrustal fault zones in active orogenic belts. Mineral precipitation in these deposits occurs under variable pressure conditions, but a mechanism explaining how the pressure regimes evolve through time has not previously been proposed. Here we show that extensional quartz veins at the G

Antimony in mine wastes: Geochemistry, mineralogy, microbiology

Antimony (Sb) is a valuable mined commodity, used mostly in fire retardants, and considered a critical element. It is also a potential environment hazard classed as a carcinogen. Antimony is concentrated in tailings and waste rock from Sb mines as well as other locations, such as precious metal deposits, where Sb is present in the ore but not recovered. This review covers the aqueous geochemistry,

Microbial endophytes and compost improve plant growth in two contrasting types of hard rock mining waste

The re-vegetation of mining wastes with native plants is a comparatively low-cost solution for mine reclamation. However, re-vegetation fails when extreme pH values, low organic matter, or high concentrations of phytotoxic elements inhibit plant establishment and growth. Our aim was to determine whether the combined addition of municipal waste compost and diazotrophic endophytes (i.e., microorgani

Source, transport and deposition of critical minerals using trace metal and isotope systematics: Denver High Resolution Laboratory

The project objective is to develop and apply solution and in situ isotopic and trace element methods to emerging research opportunities to gain a better understanding of the processes controlling critical mineral deposits, metal mobility, and other geological inquiries.

Hyperspectral Imaging of Mineral Resources from New and Old Origins: Minerals for the Nation’s Economy and Utilization of Legacy Mine Lands

This project will produce maps of surface mineralogy at 15 m spatial resolution covering the largest contiguous area of hyperspectral imagery that has ever been assembled for the U.S., over 380,000 sq. km. in California and Nevada. We are developing new methods to apply these data to map critical minerals, including minerals critical for battery fabrication, and to evaluate resources available...
