Nine Mile Metals Announces Certified Assays from DDH-WD-25-2B of 3.17% CuEq Over 15.00 Meters (7.47 g/t Ag, 0.21 g/t Au, 2.36 % Cu, 0.35% Pb, 1.29% Zn) Including 5.99% CuEq Over 6.84 Meters (14.50 g/t Ag, 0.34 g/t Au, 4.47% Cu, 0.75% Pb 2.58% Zn)

Executive Summary

• Certified assays from drill hole WD‑25‑02B reveal high‑grade copper mineralization with significant by‑product Ag and Au over two zones.
• Upper zone (56–62 m) returns 0.80 % Cu, 1.48 % Pb, 2.66 % Zn, 45.5 g/t Ag and 0.45 g/t Au (Cu‑Eq 3.20 %).
• Lower zone (107–122 m) delivers 2.36 % Cu, 0.35 % Pb, 1.29 % Zn, 7.47 g/t Ag and 0.21 g/t Au (Cu‑Eq 3.17 %), with a high‑grade interval (115.16–122 m) showing 4.47 % Cu, 0.75 % Pb, 2.58 % Zn, 14.5 g/t Ag and 0.34 g/t Au (Cu‑Eq 5.99 %).
• Results will guide the Phase 3 drill program slated for May 2026, targeting the high‑grade lens on the opposite side of a fault zone.

Key Details

• Drill Hole WD‑25‑02B – collared ~60 m NW of WD‑25‑01; azimuth 325°, dip ‑50°; terminated at 122 m due to fault and water loss.
• Assay Summary (Weighted Averages)

• Geology – Massive VMS‑type sulphides (Cu‑Pb‑Zn‑Ag‑Au) intersected in both sedimentary and volcanic units; visible chalcopyrite noted.
• Future Work – Phase 3 drilling in May 2026 will target the high‑grade lens from a new location west of the fault zone, supported by BHEM surveys (three in NW area, two in Southwest, one in high‑grade SW).
• QA/QC – Samples processed by ALS Canada Ltd. using Code ME‑ICP61A digestion and fire assay for Au; QA/QC program includes CRMs, duplicates, blanks; no material errors identified.
• Cu‑Eq Calculation – Based on April 1 2026 metal prices (Cu $5.57/lb, Pb $0.86/lb, Zn $1.48/lb, Ag $75.85/oz, Au $4,790/oz) with 80 % assumed recoveries.

Notable Quotes

• Gary Lohman, P.Geo., VP Exploration & Director: “Drilling continues to intersect massive copper‑bearing mineralization… Prior to new drilling in May 2026, BHEM surveys will be conducted on last fall’s previous holes to assist in vectoring onto newly defined VMS zones and high‑grade copper mineralization.”
• Patrick J. Cruickshank, CEO & Director: “We are thrilled with the results of this hole… Our Spring Phase 3 drill program will be exciting, and we will be able to drill from locations that best expose the value this deposit has to offer… We look forward to sharing our next result & launching our Phase 3 program.”
