Cerro de Pasco Resources Reports Additional Results from the Quiulacocha Silver-Zinc-Lead Zone

MONTREAL, Dec. 18, 2024 (GLOBE NEWSWIRE) -- Cerro de Pasco Resources Inc. (CSE: CDPR) (OTCQB: GPPRF) (FRA: N8HP) (“CDPR” or the “Company”) is pleased to report assay results for an additional seven drill holes from the Quiulacocha Tailings Project in Central Peru.

Highlights - All intersections are in core lengths from surface and correspond to the predominant silver-zinc-lead zone in the northern section of the deposit:

• Hole SPT15 intersected 19 meters (“m”) of 73.09 grams per tonne (“g/t”) silver (“Ag”), 2.10% Zinc (“Zn”), 0.90% Lead (“Pb”), and 27.30 g/t gallium (“Ga”)
• Hole SPT16 intersected 19 m of 55.44 g/t Ag, 1.64% Zn, 0.70% Pb, and 26.21 g/t Ga
• Hole SPT17 intersected 21 m of 54.71 g/t Ag, 1.50% Zn, 0.70% Pb, and 31.05 g/t Ga
• Hole SPT18 intersected 22 m of 50.27 g/t Ag, 1.31% Zn, 0.65% Pb, and 28.99 g/t Ga
• Hole SPT34 intersected 15 m of 58.77 g/t Ag, 1.79% Zn, 0.70% Pb, and 31.29 g/t Ga
• Hole SPT37 intersected 18 m at 50.51 g/t Ag, 1.28% Zn, 0.89% Pb, and 49.26 g/t Ga
• Hole SPT38 intersected 18 m at 50.38 g/t Ag, 1.48% Zn, 0.96% Pb, and 55.68 g/t Ga.
  

"Today’s drillhole results are highly encouraging and exceed our initial projections, particularly regarding silver continuity and grade,” stated Guy Goulet, CEO. “In addition to silver, zinc, lead, copper, and gold, the consistent presence of gallium exceeds expectations and provides a potentially significant upside to the project's economics. With China’s recent move to ban exports of this rare metal to the US, gallium prices have soared, with its significance now emerging for many. Representative composite samples will now undergo metallurgical testing to support future studies. These findings will inform our planning for an extended drilling campaign.”

The results demonstrate that the metal content is continuous at depth and laterally across 400 meters of the drilled area (Figure 1). The assay results for each of the seven drill holes are presented in Tables 1 to 7.

The Iron results also indicate a consistent presence of pyrite throughout the deposit. Pyrite (indicatively 50% of the tailings) may represent a valuable by-product for the project. The upcoming metallurgical test work program will also evaluate the potential for pyrite recovery, including estimated grade, by-products and impurities.

Drill Program

CDPR engaged Ingetrol Comercial S.A.C., a subsidiary of Grupo Ingetrol (Chile), and ConeTec Peru, a subsidiary of the ConeTec Group (Canada). The campaign utilizes percussion and sonic drilling techniques to ensure the most accurate results.

On October 23^rd, the Company completed the last of 40 drill holes, ahead of the rainy season, collecting more than 1,000 samples over a significant portion of the Quiulacocha tailings deposit. The samples were safely transported to the laboratory in freezer containers and are currently being analyzed.

Laboratory Testing

All samples are stored and transported to Lima in freezer containers to prevent oxidation and preserve sample integrity.

The samples are dried and tested at the Inspectorate Services Lab (Bureau Veritas) in Lima. Following geochemical and mineralogical testing, representative composites from select samples will be sent for an advanced metallurgical test work program.

The assay results are derived from a combination of multi-element ICP (detecting 60 elements), Atomic Absorption (for determining upper limits of the metals Zn, Pb, and Cu), and Fire Assay for Au.

Quality Assurance (QA) and Quality Control (QC)

The preparation of samples for Geochemical Analyses comprises drying at 100°C and riffle splitting to obtain a representative pulp sample of 250 grams. The sample does not undergo sieving or any other mechanical preparation (crushing or grinding) to preserve the original grain size distribution.

Bureau Veritas performs all sample preparation and analytical programs, supported by the QA/QC program, which is monitored on a sample lot basis. The CDPR QA/QC program consists of inserting twin samples, coarse duplicate samples, pulp duplicate samples, standard reference materials, and coarse blank material and further checking at a second laboratory. 

Geophysics

CDPR has successfully completed Phase 1 of its geophysical studies, focusing on the dry areas of the Quiulacocha Tailings. Depth readings, conducted by Geomain Ingenieros S.A.C., ranged from 20 to over 40 meters in various locations.

The Quiulacocha Tailings

CDPR is the titleholder of the concession “El Metalurgista” in Peru, which grants it the right to explore and exploit the Quiulacocha Tailings within its assigned area. The General Mining Bureau of the Peruvian Ministry of Energy and Mines has formally confirmed the enforceability of these rights.

The Quiulacocha Tailings Storage Facility covers approximately 115 hectares and is estimated to hold approximately 75 million tonnes of material processed from the 1920s to 1990s.

Initially, these tailings resulted from the mining of 16+ million tonnes of copper-silver-gold mineralization with reported historical grades of up to 10% Cu, 4 g/t Au, and over 300 g/t Ag, and later from the mining of 58+ million tonnes of zinc-lead-silver mineralized material with average historical grades of 7.41% Zn, 2.77% Pb, and 90.33 g/t Ag.

With minimal mining costs due to surface-level material and current reprocessing capacity at adjacent plants, CDPR's Quiulacocha Project stands out as one of Peru's key mining initiatives. This project provides economic benefits and aims to restore the environment and create employment opportunities, aligning with the local community's needs.
