[{"type":"text","content":"Cerro de Pasco Resources Prepares for Next Phase as Technical and Permitting Work Advances at the Quiulacocha Project\n\n\n\n MONTRÉAL, Dec. 10, 2025 (GLOBE NEWSWIRE) -- Cerro de Pasco Resources Inc. (TSXV: CDPR) (OTCMKTS: GPPRF) (BVL: CDPR) is pleased to provide a comprehensive update on the progress achieved at the Quiulacocha Tailings Reprocessing Project. This update reflects the significant advancement of technical, environmental, geotechnical, and permitting work completed under Phase 1 and the transition into Phase 2. The Quiulacocha Project represents the most strategically important tailings reprocessing and remediation initiatives in Peru, with the potential to deliver both substantial resource value and long-term environmental benefits.\n \n\n\n\n Phase 1 Achievements to Date\n \n\n\n\n\n Drilling and Mineral Resource\n \n\n\n Completion of a 40-hole sonic drill program confirming metal grades and continuity across the drilled area. Tendering and technical assessment of international contractors for Phase 2 drilling is underway. The combined Phase 1 and Phase 2 datasets will support the mineral resource estimate for the Quiulacocha tailings.\n \n\n\n Mineralogy & Metallurgy\n \n\n\n Extensive mineralogical and metallurgical test work is progressing across multiple international laboratories to determine the most effective flowsheet for recovering metals into marketable products.\n \n\n\n Environmental Baseline Studies\n \n\n\n Completion of wet season baseline studies and ongoing dry season assessments. These include drone-based LiDAR, magnetometry, and photogrammetry, as well as water quality, biological, geochemical, geotechnical, and hydrogeological monitoring.\n \n\n\n Hydrogeology and Geotechnics\n \n\n\n High resolution LiDAR, photogrammetry, and magnetometry surveys have been incorporated into hydrogeological models and stability assessments. These results guide mine planning, re mining method selection, and Phase 2 drilling infrastructure requirements.\n \n\n\n Tailings Re-mining and final storage\n \n\n\n Initial trade off assessments for long-term storage sites and re-mining methods have been completed. Rheology and abrasivity testing confirm that Quiulacocha tailings can be efficiently dredged and pumped at low cost.\n \n\n\n Permitting and Approvals\n \n\n\n Submission of the Phase 1 Results ...
