Confirmation Of High-Grade Copper-Zinc Mineralization In Phase 4 Drilling Program

TORONTO - York Harbour Metals Inc. reported on the Phase 4 drilling program at the York Harbour Copper-Zinc Project in western Newfoundland, Canada. These results further confirm the presence of high-grade copper-zinc mineralization, highlighting the potential for expanding mineral resources at the Project. In addition to these final Phase 4 assay results, the Company will provide an update on its current Phase 5 diamond drilling campaign, targeting new areas of potential high-grade Volcanogenic Massive Sulphide (VMS) mineralization.

Phase 4 played a crucial role in expanding the Company's understanding of the potential within the Main Mine area and other parts of the 4,725-hectare property, building on positive results from earlier exploration phases.

Key Highlights from the Final Outstanding Analytical Results: Drill hole YH22-73 intersected 44.93 meters of 1.292% copper including 5.36 meters of 2.938% copper; Confirmed significant high-grade copper-zinc VMS mineralization: The final assay results from the remaining four diamond drill holes of the Phase 4 program further confirmed the presence of significant copper-zinc mineralization, supporting the potential for expanded mineral resources at the York Harbour Copper-Zinc Project; Comprehensive understanding of project potential based on final drill assay results, combined with analytical findings from earlier exploration phases and most of the Phase 4 drilling program, provide an understanding of the Projects potential for expanding mineralization.

President & CEO, Bruce Durham, said, "We are pleased to report these final assay results from our Phase 4 drilling program. The continued confirmation of significant copper-zinc mineralization reinforces our belief in the potential of the York Harbour Copper-Zinc Project. As we move forward, we remain committed to unlocking further value and advancing our exploration efforts."
