• 24 Nov 2025 - Copper explorer Copper Giant (TSXV:CGNT) announced an updated mineral resource estimate for its 100%-owned Mocoa copper-molybdenum project in Colombia, which incorporates 9.5km of drilling since the 2022 MRE, enhanced geological interpretation, updated metallurgical data, and revised long-term copper and moly price assumptions. And two rigs continue to turn as part of ongoing 14km drill program at Mocoa. The inferred estimate grew tonnage by ~76% to 1.12Bt @ 0.31% Cu and 0.039% Mo for 7.6Blbs Cu (12.7 Blbs CuEq). And this copper-equivalent rises to ~14.4Blbs CuEq at our 3-month trailing average metal prices of US$4.78/lb Cu and $32.31/lb Mo with no recovery factors, which trade at CGNT market cap/lb of US$0.002/lb ($1.84/oz AuEq) - STILL a HUGE 93% discount to our 40-company copper explorer median US$0.031/lb CuEq ($25/oz AuEq). And this is AFTER the stock SURGED +36% on 24 Nov following this news, before closing the week ending (28 Nov) up +48% to 31c/sh and market cap C$45m.

The estimate is pit-constrained across 3 pockets of porphyry-style mineralization (Brama, Alba, and Melonal), and amounts to 220Mt (18% indicated) @ 0.33 g/t Au, 0.10% Cu, and 1.2% Ag (0.50 g/t AuEq) with a low strip ratio - and more growth is expected with an exploration target for an additional 345-549Mt @ 0.43-0.73g/t AuEq for additional 5-13Moz AuEq (8.6-16.5Moz cumulatively) - which is HUGE. STM stock traded flat +0% on 24 Nov following this news on strong volume (~5x avg) in-line with gold explorer group’s +0%, before closing the week ending 28 Nov up flat +0% to 2.4c/sh, market cap A$176m, market cap/oz resource US$38/oz - a 19% discount to group median $47/oz AuEq.
