What Barminco Ltd. does

Barminco Ltd. is a hard rock underground mining services contractor headquartered in Hazelmere (Perth), Western Australia, founded in 1989 in Coolgardie. It operates as the flagship contract mining subsidiary of Perenti Global Limited (ASX:PRN), an ASX-listed diversified mining services group. Barminco delivers high-speed mine development, production mining, vertical development, mine design and planning, equipment supply and maintenance, and technology services to tier-one mining companies. The company serves majors including Barrick Gold, Newmont, AngloGold Ashanti, Gold Fields, Endeavour Mining, Evolution Mining, and others, with 19 active projects across Australia, Africa (through subsidiary AUMS), Canada, and the United States, supported by a fleet of 300+ mechanized units and over 5,600 employees.

The company's revenue model is built on long-tenor contract mining services, with average contract duration of approximately 10 years and individual contract values ranging from A$120 million (Goldrush) to A$1.1 billion (Endeavour Mining). Recent major wins include the A$850 million Bellevue Gold Project contract and the A$275 million Fourmile Project contract for Barrick. Technology differentiation rests on the BROC (Barminco Remote Operating Centre), the proprietary Barminco Maintenance System, Diamec Smart 6 automated drilling, tele-remote loaders, and a 10-year automation and electrification roadmap executed in partnership with Sandvik, Epiroc, and ABB. Go-to-market is direct enterprise sales to mining majors, with on-site project teams managing HSE, mobilization, and client relationships throughout the contract life cycle.

Perenti Global, the parent, reported FY25 revenue of A$3.49 billion with net income of A$178 million and 1H26 EBITA of A$160 million (margin 9.3%, up 30 basis points year-over-year). Barminco's work-in-hand stood at A$5.8 billion against an A$18.6 billion pipeline, providing multi-year revenue visibility. Geographic expansion has been deliberate: Canada entry through the Hemlo contract in 2020, United States entry via the Goldrush contract in February 2025, and consolidation in North America through the Fourmile award in June 2026. AUMS, the African operating subsidiary, has trained over 20,000 African workers and operates in Ghana, Mali, Burkina Faso, Tanzania, and Senegal, anchoring the company's emerging-markets exposure.
