Rhea-AI Summary

Thunder Gold Corp (OTCQB:TGOLF) has completed its Phase Two drill program at the Tower Mountain Gold Property in Ontario. The company successfully drilled 13 holes totaling 1,773 metres at an all-in cost below C$260 per metre.

The program targeted multiple zones including: the P-Target (4 holes, 333 metres), the A-Target (4 holes, 357 metres), the 3738 target (4 holes, 1,008 metres) which previously yielded significant results including 35.14 g/t Au over 41.0 metres, and the H-Target (1 hole).

Thunder Bay, Ontario--(Newsfile Corp. - July 15, 2025) - Thunder Gold Corp (TSXV: TGOL) (FSE: Z25) (OTCQB: TGOLF) (formerly White Metal Resources Corp) ("Thunder Gold" or the "Company") is pleased to announce the completion of the Phase Two drill program at it's 100%-owned, 2,500 hectare, Tower Mountain Gold Property, located in the Shebandowan Greenstone Belt, 50 kilometres west of the port city of Thunder Bay, Ontario.

Highlights:

• Thirteen (13) holes (1,773 metres) of a planned 1,800 metre program completed.

• All-in cost per metre less than C $260.

Four holes (333 metres) tested the southeast limit of the P-Target, 75 metres southeast of TM24-160 (0.93 g/t Au over 41.8 metres). Four holes, (357 metres) tested the on-strike continuity of the A-Target where historical drilling failed to close this zone of at surface, high-grade mineralization along strike. One hole was drilled 50 metres northwest of TM21-117 (1.30 g/t Au over 30.0 metres). The remaining three holes were drilled 50 metres southeast of TM21-108 (3.94 g/t Au over 23.8 metres). Four holes, (1,008 metres), tested the 3738 target identified in 2023 by holes TM23-137 (35.14 g/t Au over 41.0 metres including 941.0 g/t over 1.5 metres) and TM23-138 (0.71 g/t over 119.0 metres). Table 1.0 (below) provides the collar location and orientation of the Phase Two drill holes. One hole tested the H-Target, 1,200 metres to the northwest of the P-Target (Reference: See Figure 1.0 below).

Wes Hanson, President and CEO stated, "The Phase Two drill program was completed on time and on budget with 1,773 metres of a planned 1,800 metres completed. Sample cutting is in progress and results from Phase Two are expected early to mid-August. Phase Two results will determine the scope of our Phase Three drill program, which is fully funded and expected to commence in September 2025. In the coming weeks we plan to complete infill soil geochemistry (100-metre line spacings and 25-metre sample intervals), targeting the broad, gold-in-soil anomaly parallel to the southern contact of the Tower Mountain Intrusive Complex. This area is un-tested, and the infill soil geochemistry will assist in targeting the initial drill holes in this area."

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 employed, varying only at major lithological contacts. Certified standards and blanks are randomly inserted into the sample stream and constitute approximately 5-10% 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. In addition, standards and blanks are inserted into the re-assayed interval stream to monitor analytical performance. Samples are shipped to the Activation Laboratories Ltd. facility in Thunder Bay, Ontario, where sample preparation and analyses are completed. All 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.

About the Tower Mountain Gold Property

The 100%-owned Tower Mountain Gold Property is located adjacent to the Trans-Canada highway, approximately 50-km west of the international port city of Thunder Bay, Ontario. The 2,500-hectare property surrounds the largest, exposed, intrusive complex in the eastern Shebandowan Greenstone Belt where most known gold occurrences have been described as occurring either within, or proximal to, intrusive rocks. Gold at Tower Mountain is localized within extremely altered rocks parallel to the western contact of the intrusive centre. Drilling has established anomalous gold extending out from the intrusive contact for over 500 metres along a 1,500-metre strike length, to depths of over 500 metres from surface. The remaining 75% of the perimeter surrounding the intrusion shows identical geology, alteration, and geophysical response, offering a compelling exploration opportunity.
