Thunder Bay, Ontario--(Newsfile Corp. - October 13, 2026) - Thunder Gold Corp. (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) ("Thunder Gold" or the "Company") is pleased to announce the following infill diamond drill results from the Bench Target, at the Company's flagship Tower Mountain Property, 40 kilometres west of Thunder Bay, Ontario.

Highlights:

TM25-186X extended TM25-186 252.0 metres, delivering a combined intersection of 411.0 metres averaging 0.514 g/t Au; TM25-186/186X intersected semi-continuous mineralization from collar to 90 metres and continuous gold mineralization to the end-of-hole at 501.0 metres; TM25-186X terminated in mineralization intersecting 19.5 metres averaging 0.523 g/t Au; and, The Company has contracted Expert Geophysics Surveys Inc., Newmarket, Ontario, to complete a 285 line-kilometre airborne Mobile MT ("MagnetoTellurics") survey over the Tower Mountain Intrusive Complex.

TM25-186/186X was drilled from east to west across the main Bench-3738-Ellen ("B-E") trend (Reference Table 1.0 and Figure 1.0).

Wes Hanson, President and CEO states,_"TM25-186X, drilled sub-parallel to the northern B-E contact, intersected consistent, gold grades over the entire 252-metre extension as expected, with 86% of the results assaying greater than 0.10 g/t Au. TM25-186X exceeded the model predicted grade by 18% (Reference Figure 3.0). Collectively, the eight infill holes completed to date indicate a net positive grade correlation to the January 9, 2026, Mineral Resource Estimate. The results to date continue to suggest strong, sub-vertical continuity which remains open at depth. The results also suggest average gold grade is increasing as we delve deeper into the system and site geologists are noting visible chalcopyrite at depth as well."_

"MagnetoTellurics ("MT") is a natural-source resistivity survey with a greater than 1.0-kilometre depth of investigation. It is often deployed to map alteration in porphyry copper-gold systems with useful resolution as deep as 2.0 kilometres. We believe that the MT survey may clarify alteration changes at depth, improving drill targeting as we look to test the core of the Tower Mountain system, especially as gold grades appear to be increasing with depth and we are seeing an increase in chalcopyrite, as we drill deeper into the system. The MT survey results are expected by mid-November, coincident with the final drill holes planned for the 2026 filed season."

TM25-186/186X

TM25-186 was originally drilled and reported in 2025. TM25-186X extended the original hole 252.0 metres. The combined hole parallels the northern B-E Target contact (Reference Figure 1.0). TM26-186X targeted inferred resource blocks within the optimized pit limit constraining the current MRE.

TM25-186/186X is positioned approximately 125 metres vertically above TM26-210 - 115 metres averaging 0.67 g/t Auand 250 metres below TM26-218 - 99.0m averaging 0.352 g/t Au(Reference Figure 2.0).

TM25-186/186X is mineralized from surface to the end of the hole. Table 2.0 summarizes the significant results and Table 3.0 presents the individual assays from the collar to the end-of-hole. TM25-186X intersected two narrow intervals of barren to low grade gold values over continuous down-hole intervals up to 12.0 metres in length. Otherwise, the hole is consistently mineralized from the collar to the end of the extension.

TM26-186X is the first hole where the interpreted B-E Target contact was not intersected where interpreted. The hole remained in mineralization for a horizontal distance of approximately 75 metres beyond the previously interpreted contact.

Due to the alignment and the fact that TM25-186X failed to exit the mineralization, true width cannot be estimated for this hole.

TM25-186/186X continues to suggest strong sub-vertical continuity within the B-E Target contacts. Both higher grade intervals internal to the contacts as well as barren, late mafic dikes exhibit sub-vertical continuity, essentially paralleling the interpreted contact of the Tower Mountain Intrusive Complex ("TMIC") at depth.

MagnetoTellurics Airborne Survey

Expert Geophysics Surveys Inc. ("EGS") has been contracted to complete a Mobile Magnetotellurics ("MobileMT") airborne survey of the TMIC and the magnetic low halo surrounding the TMIC outward for at least 500 metres based on current airborne magnetic surveys. A total of 285-line kilometres, spaced 100 metres apart, shall be flown in an east-west orientation across the TMIC and the prospective halo mineralization.

Numerous case studies, largely from porphyry copper-gold deposits worldwide, suggest Mobile MT can effectively isolate resistivity variation to depths of up to 2.0 kilometres from surface. The Company believes that alteration effectively controls gold mineralization and alteration can be effectively mapped from resistivity response.

The proposed 285 line-kilometre Mobile MT is planned to be completed by October 31, 2026, with initial results available by November 15th, in advance of the final drill holes planned for the 2026 field season.

MRE Reconciliation

Reconciliation of drill results to date for the Bench Target relative to the 2026 MRE model suggest an overall grade increase relative to model-predicted grades. Figure 3.0 presents a summary of model-predicted grades compared to actual drilled grade for the eight (8) infill holes completed to date. All eight holes post-date the 2026 MRE model and therefore can be compared directly to model-predicted grades to measure the predictive accuracy of the model.

The results indicate significant variation on a hole-by-hole basis, ranging from a low of -38% (TM26-214) to a high of 100% (TM26-210). This is typical and within expected tolerances. On a weighted average basis, the comparison suggests that actual drilled grades are ~10% higher than the predicted modeled grade.

Similar results are observed for the project to date drilling which includes the exploration holes completed at the UV Target and the holes drilled along the eastern margin of the 2026 MRE optimized pit limit, targeting the large un-estimated portion of the model (Reference Figure 4.0). This data set also suggests that drilled grades are returning higher values than what is currently predicted by the 2026 MRE.

Both analyses exclude mineralization intersected outside the 2026 MRE model limit, specifically, the high-grade results intersected in holes TM26-210 and TM23-137X that extend beyond the base of the 2026 MRE model.

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.
