Thunder Bay, Ontario--(Newsfile Corp. - September 14, 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:
- TM23-137X includes 294.0 metres averaging 0.418 g/t Au from collar to end of hole;
- TM23-137X terminates with an interval of 27.0 metres averaging 0.830 g/t Au, including 15.0 metres averaging 1.128 g/t Au;
68% of TM23-137X returned assays greater than the cut-off grade defining the current Mineral Resource Estimate (Jan.19, 2026);92% of TM23-137X returned assay results greater than 0.10 g/t Au, demonstrating the consistency and size of the system.
TM23-137X is an extension of TM23-137, completed in 2023, intersected three distinct gold bearing zones as follows:
41.0 metres averaging 1.81 g/t Au (CAPPED), including 1.5 metres averaging 941.0 g/t Au;
23.0 metres averaging 0.77 g/t Au and
58.0 metres averaging 0.83 g/t Au.
TM23-137X has extended gold mineralization an additional 294 metres from the end of TM23-137 and includes:
277.5 metres averaging 0.436 g/t Au
TM23-137X parallels the 650-metre long, sub-vertical zone of brecciated and altered volcanic-intrusive rocks defining the core of the Bench Target mineralization (Reference Figure 1.0). This hole targeted a large area of Inferred Resource estimated by the 2026 Mineral Resource Estimate ("MRE") with the objective of converting all or a portion of the Inferred resource to the Indicated classification in the Q4, 2026 MRE update.
Wes Hanson, President and CEO states, "TM23-137X is yet another hole demonstrating the impressive continuity and consistency of the Tower Mountain mineralization that attracted me to join the company in 2022. The hole collared in, and remained in, consistent gold mineralization for 277.5 metres to the end of the hole, extending gold mineralization 150 metres (vertically) below the current resource model and optimized pit limit. Mineralization was intersected where predicted and persisted for the entirety of the hole, as predicted. Approximately
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

About the Tower Mountain Gold Property
The 7,625-hectare,
The MRE has an effective date of January 19, 2026. A Technical Report titled " NI 43-101 Technical Report for the 2026 Mineral Resource Estimate on the Tower Mountain Project, Ontario, Canada." is available on the Company's website at www.thundergoldcorp.com and on SEDAR+ (www.sedarplus.ca) under the Company's Issuer profile.
The Report was prepared by Charley Murahwi, P.Geo., FAusIMM.; William Lewis, P.Geo., Tudorel Ciuculescu, P.Geo., and Richard Gowans, P.Eng., all of Micon International Limited ("Micon"), Toronto, Ontario, Canada. The Report was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and CIM Definition Standards of Mineral Resources and Mineral Reserves.
The MRE is summarized as follows:
Tower Mountain Mineral Resource Estimate - January 19, 2026
| Category | Tonnage (Mt) | Grade (g/t Au) | Contained Metal ('000 oz gold) | ||
| Indicated | 34.5 | 0.46 | 514 | ||
| Inferred | 211.1 | 0.45 | 3,053 |
Notes:
- The effective date of this MRE is January 19, 2026.
- Messrs. William Lewis, P.Geo., Charley Murahwi, P.Geo., FAusIMM, and Tudorel Ciuculescu, P.Geo. from Micon International Limited are the Qualified Persons (QPs) responsible for this MRE.
- The MRE has been classified in the Indicated and Inferred categories. At this time, there are no Measured resources at the Tower Mountain Project.
- The calculated gold cut-off grade is 0.19 g/t Au.
- An average specific gravity (SG) value of 2.77 g/cm3 was used.
- The MRE used economic assumptions for open pit mining. The following economic parameters were used for generating the cut-off grade: a gold price of US
$3,000 /oz,80% recovery, open pit mining cost of US$3.0 /t, processing costs of US$8.0 /t, general and administration cost of US$3.5 /t, transportation cost of US$2.5 /oz of gold, and a royalty of3% . - The open pit used slope angles of 30° in overburden and 50° in fresh rock.
- The block model is orthogonal and has a parent block size of 5 m x 5 m x 5 m, with minimum sub-block size of 2.5 m x 2.5 m x 2.5 m.
- The open pit optimization used a re-blocked size of 10 m x 10 m x 10 m.
- The mineral resources described above have been prepared in accordance with the current Canadian Institute of Mining, Metallurgy and Petroleum Standards and Practices.
- Numbers have been rounded to the nearest million tonnes and nearest thousand ounces. Differences may occur in totals due to rounding.
- Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has been insufficient exploration; however, it is reasonably expected that a significant portion of Inferred Mineral Resources could be upgraded into Indicated Mineral Resources with further exploration.
- Micon QPs have not identified any legal, political, environmental, or other relevant factors that could materially affect the potential development of the mineral resources and of the estimate.
The remaining
A second gold trend, identified in 2026, outcrops at surface and is continuously mineralized over a 100-metre width. This gold mineralization occurs within Timiskaming-type conglomerates that have been traced for over 5.0 kilometres along a southwest trend paralleling the Thunder Lake Fault. The Company believes both targets offer opportunities to materially increase the total resource through systematic drilling.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
How does TM23-137X relate to the earlier hole TM23-137?
TM23-137X was drilled as an extension of TM23-137, starting from the terminus of the 2023 hole. It added 294 metres of drilling beyond TM23-137 and intersected continuous gold mineralization, including 277.5 metres averaging 0.436 g/t Au.
What is Thunder Gold’s objective for drilling at the Bench Target?
The Bench Target hole TM23-137X was designed to test a large area of Inferred Resource defined in the 2026 Mineral Resource Estimate, with the objective of converting all or part of that Inferred material to the Indicated classification in the planned Q4 2026 MRE update.
What portion of TM23-137X lies within the current optimized pit shell?
The company states that approximately 30% of TM23-137X falls within the current optimized pit that constrains the existing mineral resource, while the remaining 70% represents additional inferred resource potential outside the current pit limit.
