Thunder Gold Corp. has intersected 294.0 metres averaging 0.418 g/t gold from collar to end of hole in diamond drill results from the Bench Target at its flagship Tower Mountain Property, located 40 kilometres west of Thunder Bay, Ontario.

The drill hole, designated TM23-137X, represents an extension of hole TM23-137 completed in 2023. The new hole collared in and remained in continuous gold mineralization for 277.5 metres to the end of the hole, terminating with an interval of 27.0 metres averaging 0.830 g/t gold, which included 15.0 metres averaging 1.128 g/t gold. Assays showed that 92% of the hole returned results greater than 0.10 g/t gold, while 68% exceeded the cut-off grade of the project's current Mineral Resource Estimate. True width cannot be estimated as the drilling failed to exit the mineralized target.

The program targeted an area of Inferred Resource defined by the January 19, 2026 Mineral Resource Estimate, which currently totals 34.5 million tonnes at 0.46 g/t gold in the Indicated category and 211.1 million tonnes at 0.45 g/t gold in the Inferred category. The objective of the drilling is to convert all or a portion of the Inferred resource to the Indicated classification in an updated Mineral Resource Estimate scheduled for release in the fourth quarter of 2026.

“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.”

Elsewhere in the surrounding district, drill hole MQD-26-474 returned 271.6 metres grading 0.73 g/t gold at Gold X2 Mining's Moss project in September 2026.
