Geochronologic analyses

The U.S. Geological Survey (USGS) Office of Acquisitions and Grants is conducting market research to identify qualified businesses capable of providing geochronologic analyses services, specifically 187Re/187Os (Rhenium-Osmium) dating analyses on mineralized rock samples. This sources sought announcement is not a formal request for proposals but rather an effort to assess the availability of qualified service providers and inform the government's acquisition strategy. Key requirements include operating a specialized geochronologic laboratory with demonstrated expertise in Re-Os geochronology applied to ore systems such as porphyry copper, molybdenum, and gold deposits, with a senior researcher or director holding advanced degrees and expertise in both Re-Os and U-Pb zircon dating techniques. Interested businesses must submit a capabilities statement detailing their ability to meet the Statement of Work requirements via email to amberry@ios.doi.gov no later than April 16, 2026, at 8:00 AM Pacific time. The government will not pay for costs incurred in preparing responses, and no formal evaluation criteria have been specified for this market research phase.

This is a total small business set-aside opportunity with no identified incumbent contractors. The contract involves analyzing 32 samples of molybdenite, pyrrhotite, or arsenopyrite-bearing mineralized rock, which must be completed within 30 days of receipt using mixed Re-double Os spike methods and state-of-the-art Triton thermal ionization mass spectrometers, with results meeting a maximum age uncertainty of 0.5% or less for molybdenites. The period of performance extends from May 30, 2026, through May 29, 2028, allowing for a two-year contract period. The specific award value or budget range has not been disclosed in this sources sought announcement. The contractor must provide their own facilities and work environment, and all data produced will become government property for public domain release. Mineral separation costs must be included in a firm fixed price quote.
