Barminco’s 23-unit Sandvik fleet at Bellevue Gold: integration notes for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Barminco has ordered a 23-unit Sandvik fleet for Bellevue Gold in Western Australia, comprising seven Toro TH663i 63‑tonne trucks, six Toro LH517i 17‑tonne loaders, five Sandvik DL432i longhole drills and five Sandvik DD422i development drills. The DD422i units will be supplied with Sandvik’s dual controls, allowing both cabin and remote operation for development headings. For mine planners and engineers, the standardised i-series fleet simplifies digital monitoring, maintenance planning and potential future automation across haulage, loading and longhole stoping.
Technical Brief
- Dual-control DD422i units enable rapid switch between manned development and tele-remote operation in high-risk headings.
- Standardised Sandvik i-series fleet allows unified telemetry, fault diagnostics and planned maintenance scheduling across all 23 units.
- Common control systems and operator interfaces reduce training time and cross-shift variability in drilling and loading performance.
- Integrated Sandvik automation-ready hardware future-proofs the fleet for phased introduction of autonomous haulage and drilling.
- Data from trucks, loaders and drills can be correlated for stope performance analysis and cycle-time optimisation.
- Single-OEM underground fleet simplifies critical spares inventory, with fewer unique wear parts and electronic components.
Our Take
The 23-unit Sandvik fleet at the Bellevue Gold project follows Barminco’s roughly A$850 million underground mining services award at the same site, signalling that Perenti is locking in standardised equipment platforms early in the contract term to de-risk ramp-up and availability.
Bellevue Gold in Western Australia now sits alongside Regis Resources’ Duketon operations in our coverage as a second major WA underground gold contract anchored by Barminco, suggesting Perenti is consolidating a strong position in high-grade underground gold across the state.
With Sandvik also featuring in recent coverage on tungsten carbide drill-bit cost pressures, the choice of DL432i and DD422i drills at Bellevue implies that consumable price volatility for tungsten-based tooling could become a non-trivial operating cost lever over the life of Barminco’s contract.
