Cerro de Pasco Resources Inc. reports that an environmental impact declaration (Declaracion Impacto Ambiental) (the "DIA") for the Quiulacocha tailings deposit located in the Simon Bolivar District of Pasco, Peru was approved through resolution RD N° 157 - 2021/MINEM-DGAAM by the Peruvian Ministry of Energy and Mines (the "MINEM") on August 3, 2021. In addition to the environmental permit, CDPR also recently obtained the technical approval of the National Water Authority (Autoridad Nacional de Agua - ANA) through technical report N° 0008-2021-ANA-DCERH/RVS, dated July 15, 2021. The DIA provides the details and coordinates for the 40-hole drilling program that CDPR intends to carry out on its El Metalurgista Concession located within the Quiulacocha tailings deposit. 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. The tailings stored in the TSF, comprised of processing residues, come from the Cerro de Pasco open pit and underground mine. The main period of tailings deposition at Quiulacocha came after 1943 when the Paragsha plant was put into commission, first treating Cu ore and later processing Zn-Pb-Ag ore. According to historical records, the Cerro de Pasco mine processed approximately 58.3 Mt of Zn-Pb-Ag ore between 1952 to 1992 from the open pit and underground workings with average historical grades of 8.6% Zn, 3.3% Pb and 98 g/t Ag. The most recent Historical Mineral Resource Estimate for the Quiulacocha tailings by BO Consulting in 2012 reported 2.9 Mt at 1.43% Zn, 0.79 % Pb, 43.1 g/t Ag, and 0.04% Cu. This estimate was based on a shallow surface auger sampling program which was estimated to represent only 4% of the expected tonnes of the deposit. The drilling program presented in the DIA is planned with sonic drilling equipment and will focus on the central, deeper section of the tailings deposit. Drilling is planned on a 100 x 100-meter grid with drill depth to be limited by the base of the deposit (lake sediments and organic material). The sampling and assaying program from the drilling will include a Quality Assurance/Quality Control (QA/QC) program which incorporates the insertion of blanks, standards, twin samples, duplicate pulps and coarse rejects and a selection of sample pulps to be sent to a secondary laboratory. After completing the sampling and assaying program and mineralogical studies, composites will be generated to undertake metallurgical studies.
