A broad Thursday: 16 companies cleared the screen across seven countries, and the headline metal mix was wider than the gold-heavy table suggests — porphyry copper-moly at Vizsla Copper's Thira, massive nickel-copper sulphide at Talon's Tamarack, high-grade Sudbury footwall copper at Magna's Levack, and 36.3 m of 311 g/t Ag at GR Silver's Plomosas. On scale, Tiger Gold's 538 m at 0.5 g/t Au from surface at Ceibal leads the gold names; First Majestic's Jerritt Canyon infill posted three 200+ g/t·m holes, but on a roughly C$10B market cap they barely move the GT/MCap needle.

CEDDH-021 is a scissor hole drilled back across the Ceibal porphyry and returned 538.1 m at 0.5 g/t Au (plus 1.0 g/t Ag and 0.07% Cu) starting at surface, with a 10 m core of 1.1 g/t from 112 m; companion hole CEDDH-020 gave 386 m at 0.6 g/t, also from surface. This is bulk-tonnage porphyry grade — it only works as a large open pit, so the continuity from surface and the confirmation from a second orientation matter more than the grade. At an approximate C$95M market cap that is 2.84× GT/MCap, and the hole ranks #26 of 1,106 gold intercepts by AuEq·m over the last 30 days; it follows a 268 m at 0.5 g/t hole (CEDDH-023) reported in October. Colombia carries moderate jurisdiction risk and open-pit permitting there is slow and contested — a bigger hurdle than geology at this stage. Watch for whether the 0.5 g/t envelope holds at depth below 540 m and how much of it clears a realistic pit cut-off. Drilled widths; true width unknown.

GT/MCap Spotlight — Top 5
Au and Cu metrics are on different price bases — not directly comparable across metals.
GR Silver tops the ratio at 88.75× on 36.3 m of 311 g/t Ag — a cross-metal figure inflated by silver's unit scale and not comparable to the gold and copper names. The best clean ratio is Metal Energy's 4.31× on 426 m of 0.17% CuEq at NIV, but that is a sub-0.2% CuEq envelope on a C$17M company in its first drill program; Tiger Gold (2.84×) and Vizsla Copper (2.34×, 366 m at 0.45% CuEq) are the more robust reads.
