York Harbour Metals Inc. announced drill core assay results for thirty-eight of forty-two holes from its 2022 Phase 4 drill campaign at its high-grade Copper-Zinc Project located 27 km west-northwest of Corner Brook, Newfoundland. The highest grade of copper-zinc drill intercept to date in the A Zone intersected above and parallel to the old mine workings which were approximately 20 metres from where the historic mineralization was mined between 1897 to 1913. The new area in the A Zone adjacent to the old mine workings returned grades comparable to historical direct-shipping mined mineralization.

(Messina 2010) o DDH YH22-107 intersected 8.97 m at 4.727% copper, 10.195% zinc, 22.69 gpt silver and 91.49 gpt cobalt (in the new area of the A Zone). Extending Mineralization of H Zone o Drill hole YH22-78 and YH22-71 continues to extend mineralization of the H Zone which remains open for expansion at depth. o DDH YH22-78 intersected multiple intercepts of mineralization, with the most significant being 8.80 m of 3.228% copper, 0.123% zinc, 3.90 gpt silver and 270.72 gpt cobalt from 190.2 to 199.0 m. o DDH YH22-71 intersected 20.5 metres of mineralization grading 1.298% copper, 0.053% zinc, 0.78 gpt silver and 118.47 gpt cobalt .

Additional follow-up/infill drilling o DDH YH22-072 was drilled to test beneath the high grade DDH YH21-24 and intersected three zones of 9.38 m (181.9 to 191.28 m) grading 3.325% copper (including 2.10 m grading 10.089% copper and 670.03 gpt cobalt), 12.80 m (202.2 to 215.0 m) grading 0.315% copper and 4.30 m (230.0 to 234.3 m) grading 0.419% copper. o Previously drilled DDH YH21-24 intersected 5.25% copper, 436.5 g/t cobalt, 8.97 gpt silver, and 0.801% zinc over a drilling length of 29.0 metres, but the hole was terminated due to ground conditions - the last sample intersecting 0.2m grading 11.9% copper. o DDH YH22-082 intersected a wide intercept of 12.25 m grading 2.472% copper, 8.404 % zinc, 18.41 gpt silver and 85.47 gpt cobalt in the D Zone.
