DOI - Critical Mineral Investigation - MRAS

The Department of the Interior (DOI), in collaboration with the U.S. General Services Administration (GSA), is conducting market research to support a critical mineral investigation initiative. This effort is part of the Bureau of Ocean Energy Management's (BOEM) Marine Minerals Program, which has been actively identifying sand resources across the Gulf of America (GOA). These resources hold significant economic value due to their use in beach replenishment and coastal protection projects. Recent studies suggest that these offshore sands may contain concentrations of heavy and critical minerals, potentially adding further economic value and contributing to national security by providing a stable supply of critical minerals.

The primary objective of this project is to enhance BOEM's National Offshore Critical Mineral Inventory (NOCMI) by characterizing critical mineral resources on the Outer Continental Shelf (OCS). The work involves performing elemental and mineralogical analyses on geotechnical cores collected from the Texas OCS. This endeavor aligns with federal priorities outlined in Executive Orders 14285 and 14154, which emphasize unleashing America's potential for exploring and developing offshore critical mineral resources. Additionally, it supports regulatory frameworks such as 30 CFR PART 581 concerning leasing minerals other than oil, gas, and sulfur on the OCS.

The scope of work includes traveling to Austin, TX, and Boca Raton, FL, where core samples are stored. The contractor will collect samples from these cores for detailed analysis. Initial tasks involve selecting a minimum of two samples from each core based on descriptions provided by BOEM geologists to ensure accurate representation. Subsequent analyses will include grain size analysis using Laser Particle Size Analysis (LPSA) and exploration-style elemental analysis focusing on critical minerals listed in the Federal Register's Final 2025 List.

Following initial analyses, further testing may be required to separate heavy minerals from select samples, calculate their distribution and mass, and determine their provenance and recoverability. The contractor will conduct monthly meetings with BOEM for ongoing input regarding sample analysis processes. Additionally, comprehensive reports summarizing findings for each core will be developed alongside data transfers to BOEM within specified timelines post-analysis completion.
