Chibougamau copper growth for Central Asia Metals: capex, schedule and mine plan lens
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Central Asia Metals’ newly acquired Chibougamau project in Quebec is modelled by BMO for steady-state output of about 20,000 tonnes of copper and 32,000 oz. of gold per year from a 900,000‑tonne‑per‑year mill, with first production targeted for late 2031 or early 2032. BMO assumes C$630 million in pre‑production capital, likely including full replacement of the historic Copper Rand plant, and a three‑year build once permitting allows construction. The 282 sq. km hub‑and‑spoke camp hosts five deposits within 50 km and current resources of 14.9 million tonnes at roughly 2.2% copper equivalent, aimed at offsetting Kounrad’s forecast decline to 6,000–9,000 tonnes by 2032.
Technical Brief
- BMO assumes full replacement of the historic 900,000 t/y Copper Rand mill rather than refurbishment.
- Existing tailings storage, hydroelectric power connection, and road/rail access at Chibougamau reduce greenfield infrastructure risk.
- Five deposits (Corner Bay, Devlin, Cedar Bay, Joe Mann, Golden Eye) sit within ~50 km of the central plant, enabling a hub-and-spoke mine plan.
- Measured and indicated resources: 6.4 Mt at 2.3% Cu, 0.8 g/t Au, 7.6 g/t Ag (149 kt Cu, 167 koz Au, ~1.6 Moz Ag).
- Inferred resources: 8.5 Mt at 2.1% Cu, 1.7 g/t Au, 7.9 g/t Ag (182 kt Cu, 454 koz Au, ~2.2 Moz Ag).
- No mineral reserves are yet defined; mine design, operating cost estimates and capital sequencing remain to be engineered.
- An updated preliminary economic assessment is scheduled for H2 2027, which will refine throughput, scheduling and capex assumptions.
- Kounrad’s August reserve update forecasts copper output dropping to 9,000 t in 2031 and 6,000 t in 2032, with leach operations extending to 2034.
- Acquisition of Cygnus Metals (0.06 CAML share per Cygnus share) transferred ownership of the entire 282 sq. km Chibougamau camp.
Our Take
The all-share Cygnus Metals acquisition on a 0.06 CAML share exchange, highlighted in our June 2, 2026 coverage, means Central Asia Metals is effectively recycling balance-sheet strength from its mature Kounrad and Sasa operations into a long-dated copper-gold growth option in Quebec rather than adding leverage.
With Kounrad copper production only guided through 2034 in earlier reporting, a Chibougamau first-output window of 2031–32 suggests Central Asia Metals is trying to avoid a mid-2030s volume cliff in its copper portfolio by overlapping the Kazakhstan dump-leach wind-down with Canadian underground feed.
