Thunder Gold intersects 298.5 m at 0.409 g/t Au at Tower Mountain

Thunder Bay, Ontario--(Newsfile Corp. - October 5, 2026) - Thunder Gold Corp. (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) (" Thunder Gold " or the " Company ") is pleased to announce the following exploration and infill diamond drill results from the Bench Target, at the Company's flagship Tower Mountain Property, 40 kilometres west of Thunder Bay, Ontario.

Highlights:

TM26-218 intersected continuous mineralization over 298.5 metres averaging 0.409 g/t Au;

TM26-218 terminated in 36.0 metres averaging 0.715 g/t Au;

TM26-215 intersected 7.5 metres averaging 0.737 g/t Au near the end-of-hole;

Results suggest that conversion of Inferred to Indicated is progressing; and

Results to date continue to suggest actual drilled grades exceed predicted model grades.

TM26-215 was an exploration hole drilled from west to east from the same pad and directly under TM26-212.

TM26-218 was drilled from east to west across the main Bench-3738-Ellen (" B-E ") trend (Reference Table 1.0 and Figure 1.0).

Wes Hanson, President and CEO states, "TM26-218 is the seventh consecutive infill hole to intersect, homogenous, continuous mineralization from the contact of the B-E trend to the end-of-hole. As with all our drilling to date, grades are very consistent, varying from 0.10 to 3.00 g/t Au within the B-E target and rarely exceeding 5.0 g/t Au. From the contact, TM26-218 intersected 298.5 metres averaging 0.409 g/t Au with the highest grade and continuity observed in the last 100 metres of the hole, approximately 300 metres from the current topographic surface (Reference Table 4.0 and Figure 2.0)."

"All seven infill holes completed to date have targeted Inferred resource blocks within the 2026 Mineral Resource Estimate (" MRE ") with the objective of converting Inferred resources to the Indicated resource classification. Actual grades are trending higher th
