Thunder Bay, Ontario--(Newsfile Corp. - October 19, 2026) - Thunder Gold Corp. (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) ("Thunder Gold" or the "Company") is pleased to announce the following exploration and infill diamond drill results from the Bench Target, at the Company's flagship Tower Mountain Property, 40 kilometres west of Thunder Bay, Ontario.

Highlights:

TM26-221 intersected 1.178 g/t Au over 102.0 metres; TM26-221 terminated in mineralization averaging 0.785 g/t Au over 12.0 metres outside the current optimized pit limit; TM26-220, 200-metres above TM26-221, intersected 0.551 g/t Au over 75.0 metres; Results continue to demonstrate good to very good spatial and empirical correlation to the 2026 Mineral Resource Estimate ('MRE"); Mineralization remains open at depth; and The Company is increasing the planned drilling at Tower Mountain based on the continuous mineralization defined by the latest drill holes.

TM26-216, 220 and 221 were drilled on a common section, testing Inferred Resources in the central portion of the Bench-3738-Ellen ("B-E") trend (Reference Table 1.0 and Figure 1.0). Table 2.0 summarizes the highlights of the three holes that are the subject of this release.

Wes Hanson, President and CEO states,_"In the past two months we have completed ten (10) infill drill holes targeting the main B-E trend, a 700-metre long, 200-metre-wide zone of variably brecciated and altered volcanic and intrusive rocks west of the Tower Mountain Intrusive Complex ("TMIC"). Collectively, these holes have intersected 3.3 kilometres of continuous gold mineralization, averaging 0.468 g/t Au, as predicted by our 2026 Mineral Resource Estimate. The system outcrops at surface and is currently drill confined at a depth of, 400 metres. Our infill drilling, on 100-metre centres, not only suggest that the system continues at depth but also, that it may be strengthening with longer, continuous intervals over 1.0 g/t Au intersected more frequently. I am pleased to note that the Infill drilling clearly demonstrates the continuity, consistency and scalability of the property that caught my attention in 2022."_

"I am also pleased to report that the MagnetoTellurics ("MT") Airborne Survey has been completed and the results are currently being reviewed / interpreted. We expect the results will highlight alteration changes at depth along the B-E trend to depths of up to 2.0 kilometres. We are also excited to see what the survey identifies within the 6.0 kilometres of untested halo circumference surrounding the TMIC."

Table 1.0 provides the location and orientation of holes TM26-216, 220 and 221

TM26-216

TM26-216 is the northern most hole on the common drill section (Reference Figures 1.0 and 2.0). It was collared north of the interpreted B-E contact, targeting scattered, low-grade gold values predicted in the model. TM26-216 intersected scattered, narrow (less than 30-metre long) intervals of mineralization at, or slightly higher than the 2026 MRE cut-off grade (0.19 g/t Au). The length, weight averaged drill hole returned an average grade slightly higher than the model predicted grade (Reference Figure 4.0).

TM26-220

TM26-220 was a step-back hole collared 100 metres south of TM26-216, targeting the upper portion of the B-E trend at the interpreted northern contact (Reference Figures 1.0 and 2.0). This hole collared and remained in semi-continuous mineralization to the end of the hole. TM26-220 intersected 75.0 metres averaging 0.551 g/t Au from 31.5 metres depth. Individual sample results range from trace to a high of 2.60 g/t Au. The hole remained in low-grade mineralization to the end of the hole, suggesting that the northern contact may be 75-100 metres further north from where it is currently interpreted (Reference Figure 2.0).

The length, weight averaged drill hole grade is slightly lower than the model predicted grade (Reference Figure 3.0).

TM26-221

TM26-221 was a 200-metre step back hole collared 200 metres south of TM26-220 (Reference Figures 1.0 and 2.0). This hole targeted the interpreted southern B-E contact. The results suggest that the southern contact is shifted approximately 50 metres to the south of the interpreted contact (Reference Figure 2.0).

TM26-221 intersected the southern B-E contact at a depth of 198.0 metres and remained in continuous, homogeneous gold mineralization to a depth of 357.0 metres, averaging 0.894 g/t Au. A large, barren mafic dike disrupts the mineralization from 357.0 metres to 438.0 metres before transitioning into continuous, homogeneous mineralization from 438.0 metres to the end-of-hole at 450.0 metres depth (Reference Tables 2.0 and 3.0).

The high grade gold intersected at the end-of-hole suggests that the hole failed to exit the target and that both the northern contact as well as the northern pit limit could extend to the north.

Gold grades ranged from trace (expressed as 0.003 g/t Au in Table 3.0) to a maximum of 3.61 g/t Au from the southern contact to the end-of-hole. The length, weight averaged drill hole grade is slightly lower than the model predicted grade (Reference Figure 3.0).

Additional drilling is planned on this section.

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 ten (10) infill holes completed to date. All ten 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 length-weighted average basis, the comparison suggests that actual drilled grade of all ten holes is ~10% higher than the predicted modeled grade.

Similar results are observed for the project to date exploration drill 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). The exploration 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.

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.

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.
