Bellevue’s Deacon North first ore: mine plan and geotechnical notes for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Bellevue Gold has delivered first ore from the high-grade Deacon North zone at its Bellevue underground gold mine in Western Australia, marking a key step in ramping up the new operation. The Deacon North orebody, part of the broader Bellevue system north of Kalgoorlie, is being accessed via underground development targeting narrow, high-grade lodes typical of the district. Early stoping performance and grade reconciliation from this area will be critical for confirming the mine plan, production schedule and geotechnical assumptions for subsequent development fronts.
Technical Brief
- Underground haulage and materials handling now need to integrate Deacon North ore into the central processing stream.
- Geotechnical domains at Deacon North are expected to be structurally controlled, consistent with Bellevue-style lode geometries.
- Early ground response in Deacon North headings will influence support patterns for subsequent mining panels.
- Lessons from Deacon North performance are likely to inform sequencing of other high-grade satellite lodes at Bellevue.
Our Take
Deacon North’s first ore follows Bellevue Gold’s decision earlier in 2026 to build a paste backfill plant for the Deacon/Deacon North areas, signalling a long-life, high-recovery underground mining strategy rather than short-cycle stoping.
Our database shows multiple recent items on Bellevue Gold’s strong cash flow and rising grades at its Western Australian operation, so ore from Deacon North is likely being integrated into an already optimised mill and cash-generative asset base.
