These technical reports evaluate the Rionegro Project in Colombia, detailing its significant potential for gold and rare earth element (REE) production. Metallurgical testing conducted by SGS confirms that magnetic separation can effectively upgrade rare earth concentrations, positioning the site competitively against global hard-rock deposits. Concurrent geological assessments define a substantial measured resource of approximately 1.3 million ounces of gold within a paleoplacer system. The documentation outlines a low-cost open-pit extraction strategy supported by established infrastructure and advanced geophysical modeling. Ultimately, an independent valuation estimates the project’s license at over US$30 million, reflecting its polymetallic richness and favorable technical feasibility.
