The Quiulacocha Tailings Reprocessing Project promotes environmental remediation, social benefits, and circular economy opportunities by reprocessing one of the world's largest above-ground metal resources.
Cerro de Pasco Resources Inc. (CDPR) is focused on the development of its principal 100% owned asset, the El Metalurgista mining concession, comprising silver-rich mineral tailings and stockpiles extracted over a century of operation from the Cerro de Pasco open pit and underground 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. The asset is one of the world’s largest above-ground metal resources.
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. Following the recent receipt of the Government Land Easement, the Company initiated at the end of August 2024, a 40-hole drill program.
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 following the acquisition of the land easement for the El Metalurgista Concession.
