Metallis completes seven drill holes at Greyhound

Executive Summary

• Metallis Resources reported completion of seven drill holes (1,143 m) on its Greyhound property in Idaho, with strong silver‑gold‑antimony intercepts at the 1350′ and Bulldog targets.
• The 1350′ target yielded multiple shear‑zone intercepts up to 25 m long, confirming a mineralized zone extending >100 m vertically and 70 m horizontally.
• Planned drilling at the Birdie target (≈500 m) aims to test a gold‑rich parallel shear zone that has already returned high‑grade historic trench samples (up to 4,900 g/t Ag and 67 g/t AuEq).

Key Details

• Overall drill program: 7 holes, 1,143 m total; drilling now moving to final Birdie target.
• 1350′ Target
• Historic channel sampling: 1.85 g/t Au, 785 g/t Ag (10.6 g/t AuEq) over 36.9 m.
• Three holes from a single pad – 659.8 m total – intersected sulphide mineralization in shear zones 7–25 m long (true width unknown).
• Mineralized zone traced >100 m vertically and 70 m horizontally; three definitive intercepts improve geometry constraints.
• Bulldog Target
• Four holes, 483.6 m total from two pads centered on a 12‑m wide silver‑gold‑antimony shear zone.
• Surface samples up to 4.9 % Sb and 3,360 g/t Ag.
• Drilling confirmed semi‑massive sulphide zones in quartz‑sulphide veins with pyrite, arsenopyrite, trace sphalerite, galena, stibnite.
• Structural analysis revealed new east‑dipping geometries; post‑mineral dikes may offset mineralization.
• Birdie Target (Planned)
• Four holes planned, ~500 m total.
• Current collaring at Upper Birdie; two scissored holes under upper portal plus two additional holes 50 m SE at lower Birdie.
• Historic trench cuts: 4,900 g/t Ag (upper), up to 67.0 g/t AuEq; quartz‑sulphide vein sample from Lower Birdie returned 18.15 g/t Au.
• Strategic Significance
• Antimony contributes ~20 % of in‑situ value; recent supply disruptions heighten its critical mineral status.
• Property hosts polymetallic shear zones with gold, silver, antimony, lead, zinc – comparable to historic Silver Valley districts.

Notable Quotes

• “This year’s drill program has delivered consistently encouraging results… We are highly encouraged by what we have seen so far and are excited to be just starting exploration on the exciting Greyhound property.” — Dave Dupre, Vice‑President of Exploration
