87 qualifying holes
4 jurisdictions
A copper-and-silver-flavoured Wednesday: 87 qualifying holes from eight companies across four jurisdictions (Canada, Argentina, Chile, Colombia). Nine Mile Metals' WD-26-18 — 11.65 m at 7.13% CuEq in a New Brunswick VMS lens, on a C$25M market cap — is the hole of the day at 3.28× GT/MCap, while AbraSilver's 228 m at 1.79 g/t Au in oxides at Diablillos posted the day's biggest gold grade-thickness (408 g/t·m, Exceptional) on a C$1.9B market cap. Discovery Mining's Dome drilling and Cadillac Mines' Galloway holes add high-grade Timmins and Quebec gold, but both sit on large caps, so their ratios stay at or below 0.05×. Ten new releases were screened; Tuesday's releases are not repeated.

Nine Mile cut 11.65 m averaging 3.23% Cu, 3.80% Zn, 1.43% Pb, 78.8 g/t Ag and 1.40 g/t Au — 7.13% CuEq — from 130.7 m, with 6.70 m at 9.93% CuEq and 4.80 m at 10.46% CuEq inside it. Widths are stated as true widths, and the zone also carries an upper 31.5 m copper stringer interval (about 0.40% CuEq). That is a classic Bathurst-camp massive-sulphide lens: a thick, polymetallic, high-grade body near surface by our ≤200 m flag, though VMS lenses are underground-mining propositions. At 83.1 %·m CuEq it rates Great and works out to 3.28× GT/MCap against a C$25M market cap; it ranks #33 of 154 copper intercepts in the last 30 days. Caveats: copper alone is 37.6 %·m (Good); the Great rating leans on zinc, silver and gold credits. The company's CuEq assumes 95% recovery on all five metals at its own August price deck (Au US$4,591/oz, Ag US$67.77/oz, Cu US$6.52/lb) and is explicitly not recoverable metal — richer than our reference prices, so treat the headline as an upper bound until metallurgy lands. Hole context is not stated. Nine Mile also appeared in this letter on Oct 16 with WD-26-15. Watch for step-outs along the lens and polymetallic recovery tests.
GT/MCap Spotlight — Top 5
Au, Ag, Cu and AuEq metrics are on different price bases — not directly comparable. The top of this list is dominated by silver-driven results (Outcrop's Santa Ana holes and Kairos's Ag-weighted interval), which are not comparable to the gold and copper names; the best clean ratios are Nine Mile's WD-26-18 (3.28×) and Kairos's 130.5 m Cu envelope (2.16×), both on micro-caps with thin trading.

Not Screened
F3 Uranium (FUU · TSX-V · C$76M) — Patterson Lake North, Canada. Hole PLN26-232 returned radiometric readings only (peak 4,400 cps over 0.5 m, 1,600 cps over the next 0.5 m, handheld spectrometer). That is not off-scale and below the 10,000 cps bar for the radiometrics watch; assays pending.
Selkirk Copper Mines (SCMI · TSX-V) — Minto, Canada. A video-enhanced re-release of the Minto North / Copper Keel / Area 118 results already reported in this letter on Oct 16 (e.g. 26SCM237: 44.7 m at 2.12% Cu); not re-screened.
Endurance Gold (EDG) — the release's two main assay tables are images, so from/to depths and fourteen further intercepts were not captured; only the intercepts described in the text are screened above. Depths shown as N/A.
Discovery Mining (DSV) — thirty-six holes reported; intervals under 1 m and lower-grade holes are not shown. DOM26-048 (1 m at 2,310 g/t Au) is a single-sample bonanza and is flagged for verification.
Outcrop Silver & Gold (OCG) — eight further holes reported no significant interval.
Drill-start and programme updates with no assays — Kingfisher Metals, SAGA Metals, Gemdale Gold, Scandium Canada, Lavras Gold, Green Bridge Metals and Quartz Mountain. Market caps for Cadillac Mines (Oct 16 close) and Kairos Gold are approximate.
