Sun Summit adds second drill rig to JD

Executive Summary

• Sun Summit added a second drill rig to the Creek zone, initiating follow‑up drilling on hole CZ‑25‑007 (78 m @ 3.72 g/t Au).
• Assays from ten additional Creek‑zone holes (3,340 m total) are pending; overall program now exceeds 5,500 m of planned drilling.
• Drilling commenced at the Finn zone and 900 m of reconnaissance drilling was completed at the Belle South Cu‑Au porphyry target; samples have been sent to the lab.

Key Details

• Second rig deployment: Follow‑up holes will test strike‑northwest and dip extensions of the high‑grade interval intersected in CZ‑25‑007.
• Pending assays: 10 new Creek‑zone drill holes (3,340 m) awaiting laboratory results.
• Program expansion: Total planned drilling at JD now >5,500 m, ~10 % greater than originally scoped for 2025.
• Finn zone start: First rig began drilling; six holes will confirm and step‑out historic high‑grade gold‑silver mineralization (e.g., 35.7 m @ 7.26 g/t Au & 94 g/t Ag).
• Historical Finn intercepts:
• JD95‑0472 – 35.7 m @ 7.26 g/t Au, 94 g/t Ag (incl. 1.0 m @ 215.4 g/t Au, 308 g/t Ag)
• JD95‑0762 – 45.0 m @ 3.02 g/t Au, 143 g/t Ag (incl. 5.0 m @ 8.18 g/t Au, 918 g/t Ag)
• JD95‑0972 – 20.85 m @ 8.76 g/t Au, 68 g/t Ag (incl. 11.0 m @ 15.1 g/t Au, 108 g/t Ag)
• JD12‑0033 – 22.0 m @ 6.32 g/t Au, 46 g/t Ag (incl. 12.6 m @ 10.8 g/t Au, 66 g/t Ag)
• Belle South porphyry target: Two reconnaissance holes totalling >900 m completed; samples dispatched for analysis to evaluate Cu‑Au potential along the 12‑km JD porphyry trend.
• NI 43‑101 disclosure: Release reviewed and approved by qualified person Ken MacDonald, P.Geo.
