Thunder Gold (OTCQB: TGOLF) reported new diamond drill results from the UV Target at its Tower Mountain gold property, 40 km west of Thunder Bay, Ontario. Six holes totaling 2,937 metres tested down-dip extensions of known mineralization and un-estimated gaps within the 2026 Mineral Resource Estimate (MRE) pit shell.
Key intercepts include hole TM26-204 with 142.0 metres averaging 0.668 g/t Au, including 45.0 metres at 1.793 g/t Au and 1.5 metres at 44.100 g/t Au, all within or adjacent to the optimized pit. Hole TM26-200 cut 238.5 metres at 0.259 g/t Au, and TM26-198 returned 39.0 metres at 0.320 g/t Au within 100 metres of surface in a new zone beside the pit. Several intervals lie above the 0.19 g/t Au MRE cut-off in areas previously modeled as waste, which the company indicates could reduce the current 1.8:1 waste-to-ore strip ratio and support growth and upgrading of the Tower Mountain resource ahead of an updated MRE.
