title. Goliath Announces 10 High‑Grade Holes Yielding Up to 7.28 g/t Au Over 8 m and 5.85 g/t Au Over 10 m in the RIRG Dyke (417–427 m depth, 500 m above valley floor) at the 1.8 km² Surebet Discovery, Golddigger Property, Golden Triangle, B.C.

• Assays are still pending for 70 holes from this year’s exploration campaign; 55 of those (≈79 %) contain up to 12 visible‑gold occurrences.
• The Bonanza zone, a series of southeast‑dipping stacked veins, now stretches 1.25 km east‑west and remains open to the northwest (≈580 m). The higher‑grade Surebet zone, composed of southwest‑dipping veins, extends 1.2 km southwest‑northeast and also stays open.
• The combined 1.8 km² gold system shows consistent width, grade and continuity, positioning it as one of the most significant recent discoveries in the Golden Triangle.

• GD‑25‑383 intersected 7.28 g/t Au over 8.0 m (including 5.85 g/t Au over 10.0 m) within an Eocene RIRG dyke. The interval also hosts 9.20 g/t Au over 5.92 m and 12.75 g/t Au over 4.02 m, all with visible gold.
• GD‑25‑311 intersected two gold‑rich veins, including 15.13 g/t Au over 3.0 m in the Bonanza zone and 2.6 g/t Au over 4.01 m in the Surebet zone.
• GD‑25‑370 returned up to 5.66 g/t Au over 5.05 m, including 9.24 g/t Au over 3.05 m from a quartz‑sulphide breccia with multiple VG‑NE occurrences.
• Additional holes (GD‑25‑387, GD‑25‑385, GD‑25‑398, GD‑25‑378, GD‑25‑410, GD‑25‑356, GD‑25‑376) recorded gold grades ranging from 4.05 g/t to 8.40 g/t Au over intervals of 3 m to 6 m, each intersecting substantial quartz‑sulphide mineralization.

The intercepts are reported as approximate true widths and reflect gold only; AuEq values will be updated once Ag, Cu, Pb and Zn assays are received. The mineralized packages include stacked quartz‑sulphide veins, Eocene RIRG dykes and calc‑silicate altered breccias, all containing visible gold from fine‑grained to coarse‑grained forms, suggesting a deep‑seated magmatic source that underpins the 1.8 km² high‑grade system.

The 2025 drill campaign surpassed the 40,000‑m plan, delivering 64,364 m of systematic drilling with nine rigs focused entirely on the Surebet discovery. The program tested the proposed mother‑lode magmatic source, examined infill targets, and expanded known veins laterally and vertically. Every hole intersected quartz‑sulphide mineralization; 83 of 110 (≈76 %) displayed visible gold, and 355 of 386 holes (≈92 %) across the entire program contain VG‑NE, underscoring the discovery’s robustness.

Surebet Discovery – Technical Overview

• More than 600 pierce points across a 1.8 km² area, intersecting 12 gold‑mineralized veins.
• High‑grade gold occurs in three distinct rock packages:
  • Gently dipping stacked quartz‑sulphide breccia/stockwork veins.
  • Eocene‑aged RIRG dykes that crosscut the veins.
  • Calc‑silicate altered breccia zones.
• All packages host visible gold, indicating a common magmatic source at depth.
• Metallurgical testing shows a 92.2 % gold recovery from gravity‑flotation at a 327‑µm crush, with 48.8 % recoverable as free gold (gravity only, no cyanide required).

2025 Drill Program – Key Metrics

• Total depth drilled: 64,364 m (vs. planned 40,000 m).
• Number of rigs: 9.
• Holes drilled: 110 (100 % intersected quartz‑sulphide mineralization).
• VG‑NE observed: 83 holes (≈76 %).
• Pending assays: 70 holes (55 contain VG‑NE).

Strategic Outlook

Goliath’s Surebet discovery now rivals historic Golden Triangle projects in terms of grade, continuity and size. The combination of multiple high‑grade veins, a pervasive RIRG dyke network and newly identified calc‑silicate breccias expands the potential tonnage while maintaining attractive grades. The company plans a 2026 follow‑up drill program (≈40–50 kt) to: (i) close the remaining assay backlog; (ii) test depth extensions of both Bonanza and Surebet zones; (iii) target the inferred magmatic source beneath the stacked veins; and (iv) refine 3‑D models with advanced geophysical and geochemical data.

With the Golddigger Property fully controlled (91,518 ha) and proximity to existing infrastructure—road access via the Dolly Varden Silver Mine Road, barge route to Prince Rupert, and power from the Kitsault community—Goliath is well positioned to advance the discovery toward a definitive resource estimate and, ultimately, a development decision.

Key Takeaways for Investors

• High‑grade, structurally controlled gold mineralization confirmed across multiple geological styles.
• Drill density (≈600 pierce points) provides a solid data foundation for 3‑D modeling and resource estimation.
• Pending assays represent a short‑term risk; however, the overwhelming majority of holes already show compelling grades and visible gold.
• Strategic positioning near existing infrastructure reduces future capex for a potential mine development.
• Goliath’s partnership with the Center to Advance the Science of Exploration to Reclamation in Mining (CASERM) provides access to advanced geoscience tools that could accelerate resource definition.
