Cerro de Pasco Reports Final Quiulacocha Assays, Confirming High-Grade Silver, Zinc, Lead, Copper, Gold, and Gallium Intersections
Cerro de Pasco Reports Final Quiulacocha Assays, Confirming High-Grade Silver,
Zinc, Lead, Copper, Gold, and Gallium Intersections
Montreal, Quebec, March 19, 2025 – Cerro de Pasco Resources Inc. (TSX.V: CDPR) (OTCQB:
GPPRF) (FRA: N8HP) (“CDPR” or the “Company”) is pleased to report final assay results from the
Quiulacocha Tailings Project in Central Peru, confirming high -grade silver, zinc, lead, and gold,
alongside significant copper intersections and increasing concentrations of gallium—a critical
metal in the high-tech and renewable energy sectors.
"Today’s drill results are very encouraging," said Guy Goulet, CEO. "The findings confirm the
consistent presence of silver and gallium across the drilled area, with average grades
exceeding 50 g/t for both metals. Notably, holes SPT1_4 and SPT1_5, located at the southern
limit of the drilling area, intersected an average of 86 g/t gallium. Within the first 8 meters,
SPT1_4 returned an impressive average of 141 g/t gallium, while SPT1_5 averaged 115 g/t,
indicating a strong enrichment near the surface. Based on these results, we anticipate that
gallium grades will continue to increase further south."
"In the central part of the drilled area, we encountered thicker layers of copper-silver-gold
(Cu-Ag-Au) tailings. The highest grades recorded in this Ag -Zn-Pb tailings area reached
0.62% Cu, 1.34 g/t gold, and 168 g/t silver. These results suggest that the intersected copper-
bearing material correlates with a later phase of copper mining associated with the open -
pit, rather than the primary underground high-grade copper zone, which is located further
south, and planned for future drilling."
Highlights - All intersections are in core lengths from surface and correspond to the predominant
silver-zinc-lead zone in the northern section of the Quiulacocha deposit:
• Hole SPT1_4 intersected 25 meters (“m”) at 53 grams per tonne (“g/t”) silver , 1.46%
zinc (“Zn”), 1.22% Lead (“Pb”), and 92 g/t gallium (“Ga”)
• Hole SPT1_5 intersected 25 m at 54 g/t Ag, 1.65% Zn, 1.23% Pb, and 80 g/t Ga
• Hole SPT08 intersected 33 m at 49 g/t Ag, 1.73% Zn, 0.66% Pb, and 33 g/t Ga
o Including a 17 m intersection at 0.19% copper (“Cu”) and 0.69 g/t gold (“Au”)
• Hole SPT09 intersected 37 m at 57 g/t Ag, 1.53% Zn, 0.73% Pb, and 38 g/t Ga
o Including an 18 m intersection at 0.24% Cu and 0.55 g/t Au
• Hole SPT19 intersected 28 m at 53 g/t Ag, 2.03% Zn, 0.95% Pb, and 46 g/t Ga
o Including a 6 m intersection at 0.18% Cu and 0.30 g/t Au
• Hole SPT20 intersected 32 m at 52 g/t Ag, 1.49% Zn, 0.86% Pb, and 44 g/t Ga
o Including a 10 m intersection at 0.20% Cu and 0.36 g/t Au
• Hole SPT29 intersected 22 m at 48 g/t Ag, 1.29% Zn, 0.79% Pb, and 46 g/t Ga
o Including a 3 m intersection at 0.23% Cu and 0.36 g/t Au
• Hole SPT30 intersected 25 m at 46 g/t Ag, 1.27% Zn, 0.80% Pb, and 48 g/t Ga
o Including a 5 m intersection at 0.17% Cu and 0.20 g/t Au
The consistent and increasing presence of gallium, a critical metal essential for advanced
electronics and renewable energy technologies, adds significant potential to the project’s
economics. Gallium’s importance has surged in response to China’s recent export restrictions to
the U.S. and other nations, driving up prices and emphasizing its strategic value in global supply
chains. This geopolitical shift underscores the urgent need for secure and diversified sources of
gallium, making our discoveries particularly well-timed.
The results demonstrate that the metal content is continuous at depth and laterally across 1,000
meters of the drilled area (Figure 1). The assay results for each of the current eight drill holes are
presented from Table 1 to Table 8.
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 preparati on of samples for Geochemical Analyses comprises drying at 100°C and riffle
splitting to obtain a representative pulp sample of 250 grams. The sample do es 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, s tandard reference
materials, and coarse blank material and further checking at a second laboratory.
