Thunder Gold Reports 121.5 metres Averaging 0.376 g/t Au in New Target Located 200 metres East of Current Resource Pit Optimization Limit

Thunder Gold Corp. (TGOL) has released exploration diamond drilling results from the Bench Target at its Tower Mountain property, located 40 km west of Thunder Bay, Ontario. The company reported data from eight holes: TM26-201, TM26-205, TM26-206, TM26-207, TM26-207A, TM26-208, TM26-209, and TM26-213. Hole TM26-207A was identified as a twin of TM26-207.
The headline result came from hole TM26-205, which intersected 121.5 m averaging 0.376 g/t Au from 465.0 m to 586.5 m. This interval is located roughly 200 m east of the current resource pit limit and approximately 400 m from surface. The company stated the target remains open in all directions. Additionally, TM26-205 intersected 158.6 m averaging 0.545 g/t Au from 4.9 m to 163.5 m, which included 54.0 m averaging 1.088 g/t Au from 6.0 m to 60.0 m.
Hole TM26-213 intersected 589.0 m averaging 0.195 g/t Au from 4.0 m to 593.0 m, including 287.7 m averaging 0.223 g/t Au. This hole drilled sub-parallel to the interpreted eastern TMIC contact toward the 110 Target.
Twinned intervals were provided by TM26-207 and TM26-207A, which returned 43.5 m at 0.341 g/t Au and 82.5 m at 0.332 g/t Au, respectively. The company noted less than 5% variation over the first 40 m between the two holes.
Thunder Gold stated that all reported holes intersected intervals above the 0.19 g/t Au cut-off in ground previously classified as waste, with the potential to reduce the waste-to-ore strip ratio. Year-to-date drilling totals 6,600 m of exploration and 3,795 m of resource definition at roughly C$250 per metre. An additional 7,500 m of resource definition drilling is planned before year-end.
Thunder Gold Corp. (TGOL) is an advanced exploration company rather than a producer, with its equity priced against resource growth, scale, and potential open-pit economics rather than near-term earnings. The stock has risen from roughly C$0.06 in January 2026 to C$0.17 prior to this release, reaching a 52-week high of C$0.20. The market has already substantially re-rated the company based on the 2026 MRE and the long, low-grade Bench drill results.
The current release is largely incremental. The TM26-205 upper zone confirms the Bench core within the pit, while the deeper 121.5 m at 0.376 g/t represents a new step-out that is below resource grade and lacks true width. The holes did not miss; they intersected gold in waste-classified ground, and the upper TM26-205 interval is above resource grade. The result is consistent with the ongoing story of a very large, low-grade system.
Expected share-price impact is likely limited. The release may support the stock but should not on its own drive a 15%+ move.

A Mineral Resource Estimate effective January 19, 2026, reports an Indicated resource of 34.5 Mt at 0.46 g/t Au for 514,000 oz, and an Inferred resource of 211.1 Mt at 0.45 g/t Au for 3,053,000 oz. The cut-off grade is 0.19 g/t Au, based on US$3,000/oz gold, 80% recovery, open-pit mining, and the stated cost assumptions.
The company has no revenue and remains dependent on equity financing. Latest reported cash was C$4.72 million as of April 30, 2026. Infrastructure is strong, with proximity to the Trans-Canada Highway, rail, hydro, and a workforce in Thunder Bay.
