Malargüe is the southernmost department of Mendoza province, sitting directly adjacent to the Vaca Muerta sedimentary basin. The silica deposit that feeds the In-Basin Sand plant lies inside this geography — 30 km from Añelo, the operational capital of the basin. This is the shortest source-to-well distance of any API 19C-certified silica origin in Argentina today.
The Malargüe deposit hosts 6 million tons indicated and 60 million tons inferred of silica mineable material. Campo Mendoza site with certified land surveys. The geology supports both +30/+70 and -70/+140 mesh cuts at the crush resistance and roundness thresholds required by API 19C.

API 19C / ISO 13503-2. SGS Minerals (Chile) report on attrition and granulometry. The geology, the mine plan and the plant design have been independently validated, and the CAPEX budget was priced by CDE Global (Ireland) for a 200 TPH wash plant.
Paved access from Malargüe to Ruta 40 and then into Neuquén. Río Colorado bridge hydraulic study evaluated three load ratings (34.5T / 60T / 90T). Water rights and Environmental Impact Assessment to be formalised during due diligence — documentation available under NDA.
At 15,000 t/month full Phase 1 capacity, the deposit supports 37+ years of extraction. That duration underwrites long-term take-or-pay structures and supports the investment thesis for a dedicated regional proppant origin.
