Infill hole hits resource grade more than 100 m below the pit at Tower Mountain
Thunder Gold drilled 232.5 m at 0.450 g/t — right on its own resource grade — and traced the system 200 m deeper ahead of a December update.
Thunder Gold drilled a single hole at its Tower Mountain project west of Thunder Bay and pulled 232.5 metres averaging 0.450 grams per tonne of gold — about a seventh of an ounce in every tonne of rock. Inside that long run sat a richer slice: 33.0 metres at 1.383 grams per tonne, roughly four-tenths of an ounce per tonne. The hole, TM26-217, is infill drilling — holes packed into a known deposit to firm up what is already there rather than to find something new. This is the kind of routine confirmation work that a resource update runs on.
Here is why the boring number is the point. That 0.450 grams per tonne is almost exactly the grade the company’s own Inferred resource model already predicted, and drilled grades are trending about 12.5% above the model’s forecast. Inferred is the lowest-confidence resource class; the goal of infill drilling is to nudge that material into the higher-confidence Indicated class before a fresh Mineral Resource Estimate the company targets for December 2026. The 33-metre high-grade streak sits against a barren dike contact and is a local feature, not a signal that the wider zone is rich. The system is bulk-tonnage, low-grade, open-pit-style rock. Notably, the hole sits 200 metres vertically below an earlier hole, TM23-137, and lands between roughly 273 and 456 metres below surface, supporting near-vertical continuity across a core the company describes as 700 metres long by 200 metres wide — extending mineralization more than 100 metres below the current pit limit. The stock backs the story: TGOL.V rose 33.3% over three months while the junior gold index gained 15.4% and gold itself added 3.5%, a step-change move through the C$0.15–0.21 range from a base near C$0.10.
Now the caveats, and they matter. The company did not state a true width for TM26-217, so the real thickness of the intercept is unknown. No cut-off grade was given for the reported intervals. Only this one hole was detailed; the other infill holes appear as single summary lines with no sub-intervals shown. And CEO Wes Hanson is both the company’s chief executive and the sole Qualified Person signing off on the technical disclosure. What to watch: the remaining infill assays before year-end, the December MRE update, and a scoping study targeted for the fourth quarter of 2026.
