Thunder Gold Corp. reports exploration and corporate developments for its gold-focused mineral exploration business in Ontario. Company news centers on the flagship Tower Mountain Gold Property in the Shebandowan Greenstone Belt west of Thunder Bay, including drill results, gold discoveries, geologic targets, mineral resource references, and land additions near the Tower Mountain Intrusive Complex.
Recurring updates also cover Ontario Junior Exploration Program funding, private placements and warrant structures, related-party financing disclosures, material agreements, investor outreach, and board or advisory-board changes. The company's releases commonly connect exploration work with property-scale geology, gold trends, sampling, drilling, and capital actions used to advance the Tower Mountain project.

Thunder Gold (TGOLF) reported new infill drilling results from its Bench Target and contracted an airborne survey at Tower Mountain.
The combined TM25-186/186X hole intersected 411.0 metres averaging 0.513 grams of gold per tonne from 90.0 to 501.0 metres. Its 252.0-metre extension ended in mineralization, with the final 19.5 metres averaging 0.523 grams per tonne. True width cannot be estimated because the hole followed the mineralized zone and did not exit it. Thunder Gold said the extension exceeded its model-predicted grade by 18%.
Expert Geophysics Surveys was contracted for a 285 line-kilometre magnetotellurics survey, which measures underground electrical resistivity. Completion is planned by October 31, 2026, with initial results expected by November 15.
Thunder Gold (TGOLF) reported a 298.5-metre gold intersection in hole TM26-218 at its Tower Mountain property in Ontario. The interval averaged 0.409 grams of gold per tonne from 100.5 metres downhole to the hole's end, including a final 36.0 metres averaging 0.715 grams per tonne. Exploration hole TM26-215 returned 7.5 metres averaging 0.737 grams per tonne near its end.
Thunder Gold said results suggest progress toward upgrading inferred resources to indicated resources, a higher-confidence classification. Its weighted comparison of seven infill holes suggests drilled grades are approximately 10% higher than model predictions. Individual-hole differences ranged from 38% below to 100% above predicted grades.
Thunder Gold (TGOLF) reported a 232.5-metre gold intercept averaging 0.450 g/t at the Bench Target of its Tower Mountain project. Hole TM26-217 included 33.0 metres averaging 1.383 g/t gold. The hole was drilled to test the edge of the January 2026 mineral resource model near the estimated open-pit limit.
Across six infill holes, reported intervals total 2,040.5 metres averaging 0.445 g/t gold, close to the model's 0.45 g/t Inferred resource grade. The company said drilled grades within the model average 12.5% above predicted grades on a weighted basis, although individual holes vary. It also said TM26-217 found mineralization more than 100 metres below the current pit limit. The program aims to convert Inferred resources to Indicated resources, with more drilling planned before a resource estimate update in December. TM26-217's true mineralized width is unknown.
Thunder Gold (TGOLF) reported new 2026 infill drill results from the Bench Target at its Tower Mountain gold project in Ontario.
Hole TM26-214 intersected 496.0 m averaging 0.271 g/t Au from 5.0 m to end-of-hole, including 409.5 m averaging 0.307 g/t Au and a higher-grade interval of 111.0 m averaging 0.514 g/t Au. Hole TM26-212 returned 592.5 m averaging 0.144 g/t Au, with semi-continuous mineralization from 376.5 m to 600.0 m, ending in 84.0 m averaging 0.442 g/t Au. Hole TM26-211 cut 396.0 m averaging 0.110 g/t Au from near surface.
The company said these holes target resource conversion within the 2026 mineral resource estimate (MRE) pit shell. A reconciliation of six Bench Target holes drilled after the 2026 MRE suggests actual drilled grades are, on a weighted-average basis, about 10% higher than modelled grades.
Thunder Gold (TGOLF) reported new diamond drill results from the Bench Target at its Tower Mountain property, including a 121.5 metre interval averaging 0.376 g/t Au in hole TM26-205, located about 200 metres east of the current 2026 mineral resource pit limit.
All seven reported holes intersected mineralization above the current MRE cut-off grade of 0.19 g/t Au in areas previously classified as waste within the optimized pit shell. Hole TM26-213 returned 287.7 metres averaging 0.223 g/t Au within a broader 589.0 metre interval averaging 0.195 g/t Au, extending the mineralized trend to the southeast. The company is operating two drills, has completed 6,600 metres of exploration and 3,795 metres of resource drilling year-to-date at all-in exploration costs of approximately C$250 per metre, and plans an additional 7,500 metres of resource definition drilling for inclusion in a year-end MRE update.
Thunder Gold (TGOLF) reported new diamond drill results from hole TM23-137X at the Bench Target on the Tower Mountain Property.
The hole extends earlier hole TM23-137 by 294 metres and returned 404.5 metres averaging 0.453 g/t Au from 297.5 to 702.0 metres, including 277.5 metres averaging 0.436 g/t Au in the TM23-137X extension. The hole terminated in 27.0 metres averaging 0.830 g/t Au, including 15.0 metres averaging 1.128 g/t Au. The company states that 68% of TM23-137X samples exceeded the cut-off grade used in the January 19, 2026 Mineral Resource Estimate, and 92% exceeded 0.10 g/t Au, extending mineralization about 150 metres below the current resource model and optimized pit.
Thunder Gold (OTCQB: TGOLF) reported new diamond drill results from the Bench Target at its Tower Mountain property near Thunder Bay, Ontario. Extension hole TM21-107X intersected 228.5 metres averaging 0.557 g/t Au, while combined holes TM21-107/107X returned 340.4 metres averaging 0.530 g/t Au.
According to Thunder Gold, TM21-107X targeted a large block of inferred resources within the 2026 mineral resource estimate, aiming to upgrade them to indicated classification. The mineralization, hosted in a brecciated and altered volcanic–intrusive sequence parallel to the Tower Mountain Intrusive Complex, remains open at depth. The company is running two drills 24/7 and expects to complete the infill program by the end of September.
Thunder Gold (OTCQB: TGOLF) reported diamond drill results from hole TM26-210 at the Bench Target on its Tower Mountain property near Thunder Bay, Ontario. The hole intersected a 661.5 metre continuously mineralized interval averaging 0.554 g/t Au, the longest such interval reported to date at the project.
Within this, Thunder Gold highlighted a 24.0 metre interval averaging 1.815 g/t Au. About 516.0 metres of the mineralized length averages 0.503 g/t Au inside the 2026 mineral resource estimate pit shell, while a further 145.5 metres averaging 0.731 g/t Au occurs immediately below the pit shell. The hole, drilled to 750 metres depth, ended in mineralization and is described by the company as supporting sub-vertical continuity and suggesting potential to expand inferred resources at depth.
Thunder Gold (OTCQB: TGOLF) reports that investors, including management, have exercised 10,229,163 share purchase warrants at $0.10 and 1,041,665 broker compensation options at $0.06, generating aggregate gross proceeds of CDN$1,085,416. These securities were originally issued in a January 24, 2025 private placement.
According to Thunder Gold, the strengthened balance sheet supports its Tower Mountain gold project, where a resource definition drill program is expected to start next week and be completed by the end of September ahead of an updated mineral resource estimate. The Tower Mountain property currently hosts an initial mineral resource of 514,000 oz indicated and 3,053,000 oz inferred, and the technical information has been reviewed by Qualified Person Wes Hanson, P.Geo.
