Technical Consultant - Potash Mining Consultant

The United States International Development Finance Corporation (DFC), through its Office of Health and Agribusiness (OHA), is seeking a technical and engineering consultant to conduct due diligence for a greenfield potash mining project in Argentina. The project employs horizontal selective solution mining, and the consultant will analyze a Preliminary Feasibility Study (PFS), validate pilot plant designs, and interpret 3D seismic data. This procurement supports the DFC's mission to mobilize private capital for development in emerging markets by ensuring technical evaluations of potential investments are thorough. The solicitation is a small business set-aside under NAICS code 541330, Engineering Services. Requirements include a subject matter expert with at least 10 years of experience in potash projects and a decade in the mining or fertilizer sectors. While the work involves evaluating assets in Argentina, services will primarily be performed in Washington, DC. Multiple amendments have refined the submission instructions and technical requirements, emphasizing a detailed analysis rather than a high-level review, including independent reserve and resource verification. The final response deadline is June 5, 2026, at 10:00 AM EDT. The work requires a detailed 'deep dive' analysis rather than a high-level review, including challenging PFS conclusions and validating cost inputs. The DFC requires a technical consultant to perform due diligence on a greenfield potash mining project in Argentina that uses horizontal selective solution mining.
