Thunder Gold to begin phase 3 drilling at Tower Mtn

Executive Summary

• Thunder Gold Corp. announced a fully‑financed Phase 3 drilling campaign at its 100% owned Tower Mountain gold property, slated to start on Oct. 1 2025 with ~2,000 m of planned drilling.
• The program will focus ~70 % on infill drilling along the 1,800‑m western contact of the Tower Mountain intrusive complex (TMIC) to close gaps in coverage and advance a pit‑constrained mineral resource estimate.
• Phase 2 results demonstrated consistent, sub‑vertical continuity with several notable intercepts (e.g., TM24‑137 = 1.80 g/t Au over 41 m), supporting the strategic shift toward an initial mineral resource estimate for the western TMIC contact.

Key Details

• Program Scope: ~2,000 m total; ~70 % infill drilling on the western TMIC contact; remaining metres held in reserve pending visual observations.
• Target Areas & Planned Holes (Phase 3):
• 3738 target: 5 holes (~1,050 m) to test a 300 × 150 m gap between Bench and Ellen targets; includes deepening of TM25‑180 by 100 m and extension drilling (TM25‑181, TM25‑183, TM25‑184/185).
• A target: 2 holes (TM25‑186 & TM25‑187) each ~100 m to test downdip continuation; additional holes may be added based on results.
• UV target (optional): Potential drilling of UV target pending winter access; highlights include TM04‑09 (1.82 g/t Au over 78 m) and TM04‑24 (0.93 g/t Au over 88.5 m).
• Phase 2 Highlights (supporting Phase 3 rationale):
• 3738 target weighted‑average: 0.93 g/t Au over 77 m; key intercepts: TM24‑137 = 1.80 g/t Au over 41 m, TM25‑178 = 1.25 g/t Au over 103.5 m.
• A target weighted‑average: 1.29 g/t Au over 22.7 m; key intercepts: TM21‑108 = 3.66 g/t Au over 23.9 m, TM21‑119 = 1.81 g/t Au over 40.5 m.
• Strategic Objectives:
• Close drill coverage gaps to strengthen geological confidence.
• Generate data for an initial mineral resource estimate (MRE) of the western TMIC contact, supporting a near‑surface, open‑pit mining scenario.
• Leverage high gold prices and existing infrastructure to accelerate development timelines.
• Quality Assurance/Control: Diamond drilling with NQ‑diameter tooling; half‑core assayed at Activation Laboratories Ltd.; certified standards/blanks inserted (~10 % of samples); fire‑assay with AAS finish; >5 g/t Au re‑assayed gravimetrically, >30 g/t Au re‑assayed via screen metallics.
• Qualified Person: Wes Hanson, P.Geo., President & CEO (NI 43‑101 qualified).
