Cerro de Pasco Resources Inc. (CDPR) is a mining and resource management company, with the goal to become the next mid-tier producer of base metals in Peru. CDPR is currently engaged in mining, developing and exploring our wholly-owned 6,000 hectare Santander Mine in the highly prospective Antamina-Yauricocha Skarn Corridor, located 215 km from Lima. CDPR is also focused on the development of its principal 100% owned assest, El Metallurgista mining concession comprising mineral tailings and stockpiles extracted from the historical Cerro de Pasco open-pit mine in central Peru. The company’s approach at El Metalurgista entails the reprocessing and environmental remediation of mining waste and the creation of numerous opportunities in a circular economy. CDPR founded on clear the objectives, to engender long-term economic sustainability and benefit for the local population, from an economic, social and health point of view.
The Santander Mine is a steady state, fully permitted mining and processing operation with good community relations. It is composed of a modern 2,500 tonne per day processing facility and underground mine. Mineral rights encompass an area of 5,456.57 ha of highly prospective area. Mining is currently taking place at the Magistral deposit with plans to begin mining of the Santander Pipe in the coming years. In 2022 CDPR concluded a 30,000M exploration and infill drilling program with the purpose of increasing the Mineral Resources and Reserves.
The Quiulacocha tailings deposit covers approximately 115 hectares with tailings deposited in the Quiulacocha Tailings Storage Facility (TSF) from the early 1920´s to 1992. Approximately 57 ha of the Quiulacocha TSF lies within CDPR’s El Metalurgista mining concession. Initially these tailings resulted from the mining of copper-silver-gold mineralization with reported historical head grades of up to 10% Cu, 4g/t Au and over 300g/t Ag and later from the mining of zinc-lead-silver mineralized material with average historical grades of 7.41% Zn, 2.77% Pb and 90.33g/t Ag.
The Excelsior Stockpile covers a surface area of 67.92ha and contains approximately 70 Mt of broken rock. The stockpile was in use between approximately 1970 and 1996 to store what was then considered uneconomic/low grade mineralization from the Raul Rojas open pit. The surface area of the Excelsior stockpile lying within the El Metalurgista mining concession is approximately 35ha. CDPR recently issued an Inferred Mineral Resource of 30.10 Mt grading 44 g/t Ag, 0.6% Pb and 1.5% Zn, containing 42.9 Million ounces of silver, 437,000 tonnes of zinc and 184,000 tonnes of lead. The Excelsior Mineral Resource has potential to increase significantly if CDPR can acquire government owned surface rights that surround the El Metalurgista concession.
