Description
The U.S. Geological Survey (USGS) seeks a qualified small‑business contractor to perform heavy mineral separation on rock and sediment samples for in‑situ geochronology and isotope tracer studies. The work involves receiving samples, processing them using electro‑pulse disaggregation and density/magnetic separation techniques, labeling and returning mineral separates, and delivering detailed spreadsheet reports of methods and results. The contract is firm‑fixed‑price, runs from 1 Oct 2026 to 30 Sep 2027, and will be awarded to the lowest priced technically acceptable offer. • Receive and log rock/sediment samples within 2 business days. • Perform heavy‑mineral separation (electro‑pulse, density, magnetic) within five weeks of receipt. • Provide Excel reports describing procedures and mineral splits. • Return all mineral fractions and residual material to USGS. • Maintain a dedicated mineral‑separation facility with trained staff. • Contract value expected to be well below the $21 M small‑business size standard.
