Thunder Gold Intersects 661.5 Metres of Continuous Gold Mineralization Averaging 0.554 g/t Au
Rhea-AI Summary
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 Bay, Ontario--(Newsfile Corp. - August 11, 2026) - Thunder Gold Corp. (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) ("Thunder Gold" or the "Company") is pleased to announce exploration diamond drill results from the Bench Target, at the Company's flagship Tower Mountain Property, 40 kilometres west of Thunder Bay, Ontario.
Highlights:
- Longest continuously mineralized interval reported to date: 661.5 metres averaging 0.554 g/t Au;
- Longest continuous interval greater than 1.0 g/t Au: 24.0 metres averaging 1.815 g/t Au;
- Strong resource expansion relevance: 516.0 metres averaging 0.503 g/t Au inside 2026 Mineral Resource Estimate ("MRE") pit shell;
- Mineralization extends below the current pit shell: 145.5 metres averaging 0.731 g/t Au immediately below MRE pit shell;
- Hole TM26-210 ended in mineralization: Supports the interpreted sub-vertical continuity of the Bench target and indicates the alteration system remains open down-dip.
TM26-210 targeted the interpreted continuation of the 300+ metre wide, sub-vertical zone of brecciated and altered volcanic-intrusive rocks of the Bench Target. The hole followed the eastern edge of the current optimized pit constraining the 2026 MRE, along the 100-metre interpolation limit utilized to estimate inferred resources. The hole lies 100 metres below holes TM21-120 (399.0 metres averaging 0.458 g/t Au) and TM22-134 (318.0 metres averaging 0.452 g/t Au), both of which terminated prematurely in mineralization (Reference Figure 1.0). Elevated gold values were intersected 50 metres earlier than anticipated and continued 75 metres past the interpreted lower limit. The hole ended in mineralization suggesting potential to further increase the inferred resource at depth.
Wes Hanson, President and CEO, states, "TM26-210 was an across-the-board success, currently the best hole ever reported at Tower Mountain. The hole clearly demonstrates potential to increase resources immediately adjacent to the currently defined optimized pit constraining the 2026 MRE with the deepest portion of the hole returning broad, consistent mineralization greater than 1.0 g/t Au on a sustained basis with an absence of outlier values. It clearly supports the 100-metre search radius used for the 2026 MRE and demonstrates that there are immediate opportunities with, and immediately adjacent to the optimized pit to increase and reclassify the 2026 MRE. This hole clearly supports our assertion that drilling to date has failed to adequately define the limits of the alteration halo hosting mineralization. The results certainly support the sub-vertical continuity of the zone and demonstrate potential for additional discovery at depth."
Mineralization occurs entirely within a sub-vertical, variably brecciated and altered sequence of intermediate volcanics and alkalic intrusives parallel to the central Tower Mountain Intrusive Complex ("TMIC") The brecciated sequence is cut by millimetre scale quartz-carbonate-tourmaline stockworks. Pyrite, ranging from trace to

Table 2.0 (below) summarizes the entirety of TM26-210 from the bedrock-overburden contact to the end of the hole which terminated in mineralization. Three (3) barren dikes were intersected within the mineralized zone at 129.0 metres (27.0 metres), 189.0 metres (7.5 metres) and 733.5 metres (12.0 metres), collectively representing
Four (4) intervals returned average grades less than the 0.19 g/t cut-off grade used to define the 2026 MRE.
The bottom of the hole, under the current optimized pit limit used to report the 2026 MRE returned the longest, continuous interval greater than 1.0 g/t Au ever observed at Tower Mountain, clearly demonstrating opportunity to not only increase mineral resource but suggesting that the system may be strengthening with depth.
Approximately 516 metres of the reported 661.5 metre interval is within the current optimized pit shell defining the 2026 MRE.

The information contained herein contains "forward-looking information" and "forward-looking statements" within the meaning of applicable securities legislation (collectively, "forward-looking statements"). Forward-looking statements relate to information that is based on assumptions of management, forecasts of future results, and estimates of amounts not yet determinable. All statements, other than statements of historical fact, are forward-looking statements and are based on predictions, expectations, beliefs, plans, projections, objectives and assumptions made as of the date of this news release, including without limitation: statements regarding the potential to increase, expand, or reclassify the 2026 Mineral Resource Estimate; the interpreted geological continuity, sub-vertical extent, and depth potential of the Bench Target and the broader alteration system hosting mineralization at Tower Mountain; the anticipated timing and results of ongoing and future drill programs; the Company's plans regarding further definition, expansion, and discovery drilling at Tower Mountain; and the Company's plans regarding exploring its mineral exploration properties generally, anticipated results of geophysical drilling programs, geological interpretations and potential mineral recovery. Any statement that involves discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions, future events or performance (often but not always using phrases such as "expects", or "does not expect", "is expected", "anticipates" or "does not anticipate", "plans", "budget", "scheduled", "forecasts", "estimates", "believes" or "intends" or variations of such words and phrases or stating that certain actions, events or results "may" or "could", "would", "might" or "will" be taken to occur or be achieved) are not statements of historical fact and may be forward-looking statements.
Forward-looking statements are subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation: risks related to failure to obtain adequate funding on a timely basis and on acceptable terms; risks related to the outcome of legal proceedings; political and regulatory risks associated with mining and exploration; risks related to the maintenance of stock exchange listings; risks related to environmental regulation and liability; the potential for delays in exploration or development activities or the completion of feasibility studies; the uncertainty of profitability; risks and uncertainties relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits; risks related to the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses; results of prefeasibility and feasibility studies, and the possibility that future exploration, development or mining results will not be consistent with the Company's expectations; risks related to the gold price and other commodity price fluctuations; and other risks and uncertainties related to the Company's prospects, properties and business detailed elsewhere in the Company's disclosure record. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Investors are cautioned against attributing undue certainty or reliance on forward-looking statements. These forward-looking statements are made as of the date hereof and the Company does not assume any obligation to update or revise any forward-looking statements, other than as required by applicable law, to reflect new information, events or circumstances, or changes in management's estimates, projections or opinions.
