Ten companies cleared the screen on Thursday, and it was a critical-minerals and porphyry-copper day more than a gold one: Defense Metals’ Wicheeda drilling (153.2 m at 2.33% TREO), Brunswick Exploration’s 202.5 m at 1.31% Li₂O in Québec and NorthWest Copper’s 108.7 m at 2.53% CuEq at Kwanika (a second straight day on the sheet) lead on GT/MCap, with Oroco and Hot Chili adding Americas porphyry copper and Arras posting 574 m at 0.40% CuEq plus 22.8 m at 5.37 g/t Au in Kazakhstan. Gold is dominated by two large-footprint, low-grade programs: Spanish Mountain’s 295.5 m at 0.54 g/t Au and Discovery Silver’s Pamour infill, which carries the biggest raw grades (5.1 m at 42.37 g/t Au) but sits on a C$9.3B market cap, so its GT/MCap is negligible. Equity Metals’ Ag/Zn-rich Silver Queen vein composites rate well on reported AuEq but are narrow and cross-metal.

AuEq: Au $3,200/oz · Ag $33/oz · Cu $13,700/t · Li₂O $15,000/t · GT/MCap uses C$ mkt cap at October 8, 2026; some market caps are approximate. Rows where the company reports an equivalent grade (CuEq, AuEq) are rated on that equivalent. REE AuEq requires NdPr% disclosure; “N/A” if basket not specified.
Altamira Gold (ALTA · TSX-V · C$71M) — Maria Bonita, Brazil. Trench results of 114 m at 0.7 g/t Au (incl. 36 m at 1.3 g/t) are trench sampling, not drilling, and are not archived; the drill intercepts are in the table.
Metalsource Mining (MSM · CSE · C$53M) — Silver Hill. Phase 2 drilling launch; drill assays pending. Only surface rock-chip sampling reported.
Kenorland Minerals (KLD · TSX-V · C$195M) — South Uchi, Ontario. Phase 4 drill program start; previously reported intercepts restated, not re-counted.
Daura Gold (DGC · TSX-V · C$21M), Nicola Mining (NIM · TSX-V · C$149M), Alaska Silver (WAM · TSX-V · C$51M), Decade Resources (DEC · TSX-V · C$38M) — Program start/completion updates or visual core observations only; assays pending.
Silver X Mining (AGX · TSX-V · C$249M), Eureka Metals (ERKA · CSE · C$10M) — Production update (no drilling) and surface grab-sample scandium results (no drilling).
Benton Resources (BEX), AuMEGA Metals (AUM), Spark Energy Minerals (SPRK) — Surface, channel or grab sampling headlines (no drill assays); not itemised.
Coverage gaps — Arras and Altamira publish parts of their assay tables as images, so Arras end-depths are derived from reported intervals and some sub-intervals are not itemised. Market caps for Spanish Mountain, Arras, Melkior and IMC are approximate. Equity Metals’ AuEq figures are reported composites on select intervals. Discovery Silver omitted ten lower-grade holes from its table. Sub-intervals (“including”) are archived only where they are the headline result. Oroco S050 (6.0 m, Zn-Pb-Ag skarn-style) is below its 10 m reporting minimum and is not itemised. Defense Metals WI26-102 was reported earlier and is not re-counted.
