On July 16, 2026, Thunder Gold Corp. (“Thunder Gold”) announced exploration diamond drill results from the UV target, at the Tower Mountain property. Six holes totaling 2,937 m targeted the down-dip projection of the main mineralized trend observed in historical diamond drill holes completed from 2002 to 2005. Three holes targeted the projected trend 100 to 150 m below the current bottom of the optimized pit constraining the 2026 MRE. The remaining holes targeted gaps in the MRE where there was insufficient drill data to estimate gold grades. Drilling has confirmed that the main mineralized trend at UV continues at depth and remains open, with grades and widths consistent with historical drilling and the 2026 MRE. Importantly, multiple new zones of mineralization above the 2026 MRE cut-off grade of 0.19 g/t Au were intersected in areas previously modeled as waste, providing potential to reduce the current 1.8:1 waste-to- ore strip ratio defined within the optimized pit.
