Cerro de Pasco Reports Final Quiulacocha Assays, Confirming High-Grade Silver, Zinc, Lead, Copper, Gold, and Gallium Intersections

MONTREAL, March 19, 2025 (GLOBE NEWSWIRE) -- 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
  • 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
  • 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
  • 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
  • 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
  • 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
  • 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.
