NOI - Sulfide Analysis

The U.S. Geological Survey issued a notice of intent on May 6, 2026 to award a single-source purchase order to AIRIE LLC for sulfide analysis services, with quotation responses due by email to Anthony_berry@ios.doi.gov no later than May 12, 2026 at 0800 hours PDT. This is a total small business set-aside. Although the USGS identifies AIRIE LLC as the only known source capable of providing the required sulfide analysis, the notice invites all responsible parties to submit quotations for the agency's consideration; the Government reserves sole discretion to determine whether to compete the action based on responses received.

The statement of work requires geochronologic analysis of approximately 32 samples containing molybdenite, pyrrhotite, or arsenopyrite-bearing mineralization collected from Alaska using 187Re/187Os dating techniques. The contractor must operate a high-quality laboratory with demonstrated expertise in Re-Os dating and porphyry system geology, complete analysis within 30 days of sample receipt, employ a mixed Re-double Os spike method with Triton thermal ionization mass spectrometers, achieve uncertainty of 0.5 percent or less for molybdenites, and deliver publication-ready reports with analytical data and interpretation. The senior researcher or director must hold advanced degrees and expertise in ore geology with integration of Re-Os and U-Pb zircon methods. Performance occurs at the contractor's laboratory from May 30, 2026 through May 29, 2028. All data produced becomes Government property for public domain release. NAICS 541380 (Testing Laboratories and Services) applies with a $19.0 million size standard.
