Minerals 260’s Bullabulling gold project: schedule and pit design notes for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Minerals 260 has advanced its Bullabulling gold project near Coolgardie, Western Australia, into a new phase targeting first gold in late 2028 and growth beyond the current 6.2‑million‑ounce mineral resource estimate. The program combines infill and extensional drilling on the main Bullabulling Trend with regional exploration across newly consolidated tenure to test additional shear‑hosted gold targets. Workstreams now also include mining studies and project approvals to bring the open‑pit operation to production readiness on a similar timeframe to other large-scale WA gold projects.
Technical Brief
- Exploration and study phases are being sequenced to deliver production readiness aligned with internal development timelines.
- For comparable WA gold projects, this coupling of regional exploration and mine studies is becoming standard practice.
Our Take
Bullabulling’s 6.2Moz mineral resource puts it at the upper end of Western Australian gold development stories in our database, which typically report sub-3Moz resources at the pre-production stage.
The late-2028 first gold target aligns with earlier related coverage of high-grade intercepts at Bullabulling (Dec 2025 and Mar 2026), suggesting Minerals 260 is now transitioning from resource growth drilling to a more defined development schedule rather than pure exploration.
Within our 410 gold-tagged pieces, relatively few projects in Western Australia are currently flagged with both ‘Projects’ and ‘Contract Award’ tags, indicating Bullabulling is moving into a more advanced execution phase compared with many peer gold plays still in pure study or drilling mode.
