Thunder Gold Identifies New Gold Discovery At Tower Mountain Property, Shebandowan Greenstone Belt, Ontario.

Thunder Gold Corp. has announced significant drill results from its 2026 exploration program at the Tower Mountain Property in Ontario's Shebandowan Greenstone Belt, revealing a new gold discovery that substantially expands the project's potential. The Star Target, located 500 metres west of the current optimized pit limit that defines the existing Mineral Resource Estimate, has returned impressive near-surface gold intercepts including 73.5 metres averaging 0.364 g/t gold with higher-grade zones of 16.5 metres at 0.779 g/t gold.

The discovery occurs within a 200-metre-wide Timiskaming conglomerate unit that has been mapped over 5 kilometres, suggesting significant exploration potential along this geological trend. Historical work by previous operators including Hemlo Gold Mines and Avalon Ventures had identified gold occurrences along this trend, with grades reaching up to 82.50 g/t gold in surface samples. The current drilling has confirmed the continuity and economic potential of this mineralization, with all reported grades exceeding the 0.19 g/t gold cut-off grade used in the recent resource estimate.

This discovery is particularly significant as it effectively doubles Thunder Gold's target opportunities within a manageable 5-kilometre radius around Tower Mountain. The company's current mineral resource totals 63.8 million tonnes at 0.65 g/t gold for 1.33 million ounces in the indicated category, plus 28.0 million tonnes at 0.61 g/t gold for 549,000 ounces inferred. With an all-in discovery cost of just C$3.95 per inferred resource ounce and excellent infrastructure access including year-round paved highway access and proximity to the port of Thunder Bay, the project presents a compelling development opportunity.

The company is currently executing a 15,000-metre drill program focused primarily on converting inferred resources to the indicated classification within the existing pit shell, while the new Star Target discovery provides additional upside potential for future resource growth. The strategic location, established infrastructure, and now expanded exploration potential position Tower Mountain as an increasingly attractive gold development project in a mining-friendly jurisdiction.
