30 Second Briefing
Major Drilling Group International is moving into large-scale mine dewatering by acquiring Western Australia–based Bunbury Drilling Company for an upfront A$50 million, with a further A$20 million earn-out tied to performance. BDC brings a fleet focused on high-capacity dewatering and depressurisation wells for iron ore and other open pits in the Pilbara and wider WA, complementing Major Drilling’s existing exploration and specialised drilling services. The deal signals growing demand for dedicated hydrogeological drilling capability as deeper pits and higher rainfall variability increase groundwater management risk.
Technical Brief
- Acquisition is executed via Major Drilling Pty Ltd, integrating BDC directly into its Australian operating structure.
Our Take
Western Australia dominates the Projects-tagged mining coverage, and adding Bunbury-based capacity positions Major Drilling Pty Ltd to capture dewatering and hydrogeological packages on large iron ore and gold operations that increasingly bundle drilling and water management under single contracts.
