Thunder Gold Reports 404.5 Metres of

Continuous Gold Mineralization Averaging

0.453 g/t Au in Extension of TM23-137

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 30% of TM23-137X falls within the current

optimized pit constraining the current mineral resource for the project. The remaining 70% of the hole

represents additional inferred resource potential. More importantly, this is the third deep hole in a row

that extended the system and indicates that the system may be strengthening with 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 5% (locally) is persistent throughout all observed lithologies except late

dikes.

original hole TM23-137 completed in 2023.

Quality Assurance and Quality Control

Diamond drilling utilizes NQ diameter tooling. The core is received at the on-site logging facility where it

is, photographed, logged for geotechnical, physical properties and geological data. Samples are

identified, recorded, and cut in half by wet diamond saw. Half the core is sent for assay at an accredited

laboratory with the remaining half core stored on site. A standard sample length of 1.5 meters is typically

employed, varying only at major lithological contacts.

Certified standards and blanks are randomly inserted into the sample stream and constitute

approximately 10% of the sample stream.

Certified standards and blank performance is monitored with

any failures evaluated and investigated to determine if said failure is a result of error during submission.

Any unexplained failures are identified and the five samples preceding and following the failure are re-

assayed. Commencing in 2026, duplicate pulps are prepared at a rate of 1 in every 20 samples. The

duplicate pulps are sent to a second independent analytical facility for analyses.

Activation Laboratories Ltd., Thunder Bay, Ontario, ISO/IEC 17025:2017 is the primary independent

analytical service provider.

AGAT Laboratories, Thunder Bay, Ontario, ISO/IEC 17025:2017 is the secondary, independent

analytical facility.

Samples are, received, dried, crushed to 80% passing 2.0 mm. A 250-gram sample is split and

pulverized. Samples are analyzed for gold using a 30-gram lead collection fire assay fusion (FA) with an

atomic absorption (AAS) finish. All assay results greater than 5.0 g/t Au are re-assayed using a

gravimetric analysis. All assays greater than 30.0 g/t Au are re-assayed using screen metallics where a

representative 1000-gram sample is split sieved at 149µm. Assays are performed on the entire +149

µm fraction and two splits of the -149 µm fraction. A final assay is calculated based on the weight of

each size fraction.

Qualified Person

Technical information in this news release has been reviewed and approved by Wes Hanson, P.Geo.,

President and CEO of Thunder Gold Corp., who is a Qualified Person under the definitions established

by NI 43-101.

About the Tower Mountain Gold Property

The 7,625-hectare, 100%-owned Tower Mountain Property is beside the Trans-Canada highway, 40-km

west of Thunder Bay, Ontario (pop. 120,000). Gold mineralization occurs in variably brecciated and

altered rocks surrounding the calc-alkalic Tower Mountain Intrusive Complex ("

TMIC

"). Drilling to date

has established an initial mineral resource parallel to the western contact of the intrusion representing

approximately 25% of the TMIC halo.

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:

Notes:

1

.

The effective date of this MRE is January 19, 2026.

2

.

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.

3

.

The MRE has been classified in the Indicated and Inferred categories. At this time, there are no Measured resources at the Tower Mountain

Project.

4

.

The calculated gold cut-off grade is 0.19 g/t Au.

5

.

An average specific gravity (SG) value of 2.77 g/cm

3

was used.

6

.

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 of 3%.

7

.

The open pit used slope angles of 30° in overburden and 50° in fresh rock.

8

.

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.

9

.

The open pit optimization used a re-blocked size of 10 m x 10 m x 10 m.

10

.

The mineral resources described above have been prepared in accordance with the current Canadian Institute of Mining, Metallurgy and

Petroleum Standards and Practices.

11

.

Numbers have been rounded to the nearest million tonnes and nearest thousand ounces. Differences may occur in totals due to rounding.

12

.

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.

13

.

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 75% of the TMIC halo demonstrates similar geology, alteration, and geophysical

signatures and is untested by drilling.

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.
