Volume was heavy after the weekend gap, but the two biggest releases by row count — B2Gold's Back River infill program and Dakota Gold's Richmond Hill resource expansion — are mega-cap and large-cap stories where even Exceptional-tier grades barely move the GT/MCap needle. The value-per-dollar story today belongs to two smaller copper names: Eastport Critical Metals' Botswana hit and Gladiator Metals' new Yukon skarn discovery. Thunder Gold's wide Tower Mountain infill hole narrowly out-points Austral Gold's Chilean AuEq intercept for Hole of the Day — about as close a call as this framework produces. Four jurisdictions today (Canada, USA, Chile, Botswana), all Stable or Low-Moderate — no risk flags. Both TSX and NYSE/Nasdaq traded normally.

6-hole infill, +12.5% vs model
232.5 metres averaging 0.450 g/t Au from 360m depth, including a higher-grade 33.0m core at 1.383 g/t Au — the sixth hole of an infill program converting Inferred ounces to Indicated at Tower Mountain, Ontario. This is a wide, moderate-grade intrusion-hosted system rather than a bonanza vein: width is doing the work, not grade, and the company's own six-hole aggregate (2,040.5m @ 0.445 g/t Au) is running roughly 12.5% above the modelled grade. Deep hole (from 360m) means no open-pit read-through — this is underground resource-conversion economics, not a discovery story. On raw GT it narrowly out-points Austral Gold's Guanaco hit (104.6 vs 104.5 AuEq·m) — about as close as this selection procedure gets. At a C$55.53M market cap, 1.88× GT/MCap is the second-best on the sheet today, trailing only Eastport's copper hit. Ranks #146 of 845 Au intercepts in the trailing local archive — solidly mid-table on grade, but a program worth watching given the aggregate result. No prior qualifying history in the local archive (first appearance).

Solitario Resources Corp. (XPL/SLR · NYSE American/TSX · C$85.2M) — Cat Creek copper-molybdenum porphyry project, Colorado, USA. Two holes logged visual molybdenite over up to 382.9m with trace pXRF copper; no lab assays returned. Visual/pXRF intercept only — lab assays expected in 2-3 months, no GT threshold applicable to unassayed visual logging.

Talisker Resources Ltd. (TSK · TSX · C$254.7M) — Mustang Mine (M1 Vein), Bralorne Gold Project, BC, Canada. Underground face/channel samples averaging 27.88 g/t Au across a 36m strike length (0.61m average true width), including a 229.0 g/t Au face sample. Channel/face sample, not a drill hole — outside this newsletter's drill-results scope.

Xcite Uranium Inc. (XRI · CSE · C$26.6M) and Green Canada Uranium Corp. (GCUC · TSXV) both reported downhole gamma anomalies today (peak 2,281 cps and 3,806 cps respectively) — below the Radiometric Watch inclusion bar (off-scale or peak ≥10,000 cps) and not described as probe-saturated by either issuer, so neither is carried as a leading indicator this run.
