Artemis Gold Blackwater Phase 2: throughput expansion lens for mine planners
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Artemis Gold has approved an expanded Phase 2 (EP2) development for its Blackwater gold mine in central British Columbia, increasing planned processing plant capacity beyond the 8 Mt/y targeted in the Phase 1A project now under construction. Phase 1A is scheduled to reach the 8 Mt/y run rate before the end of 2026, with EP2 adding a substantial incremental throughput above this baseline. The decision signals earlier scaling of comminution, materials handling and tailings infrastructure, with implications for mine scheduling, power demand and long-lead process equipment procurement.
Technical Brief
- Integration of EP2 with the Phase 1A flowsheet will drive redesign of plant layout tie-ins.
- Tailings storage facility staging must now accommodate higher near-term deposition rates and revised embankment raise sequencing.
- Power supply planning for Blackwater will require updated load forecasts and potential substation/line capacity upgrades.
- Mine scheduling will be re-optimised to deliver higher early ore tonnage while maintaining strip ratio constraints.
- Procurement teams can now align EP2 contracts with existing Phase 1A packages to capture pricing synergies.
- Construction sequencing will need revised earthworks, foundations and structural steel phasing to minimise plant downtime.
- For similar greenfield gold projects, earlier multi-phase plant upsizing tends to compress payback but increase execution complexity.
Our Take
With Blackwater in central British Columbia advancing, and Eskay Creek in the Golden Triangle also progressing IBAs per our recent coverage, gold projects in B.C. are moving in parallel towards construction decisions, which may tighten regional competition for skilled labour and contractors by the 2026 timeframe.
The planned 8 Mt/y processing capacity for Blackwater Phase 1A positions Artemis Gold among the larger-scale gold developments in our database, suggesting the Phase 2 board approval is likely tied to securing a long-life, low unit-cost profile rather than a marginal capacity increment.
Our coverage shows several Canadian gold assets, such as Seabridge Gold’s planned spin-out of Courageous Lake into Valor Gold, being restructured or expanded, indicating that Artemis Gold’s Blackwater build-out is occurring in a capital-raising environment where scale and project optionality are being actively emphasised by operators.
