Jahkai is a majority Aboriginal-owned, 100% Australian mining services enterprise with full-spectrum capability across underground mining, tunnelling, drill and blast, haulage, equipment supply, workforce development, and mine planning. Our Managing Director holds the highest international qualifications in underground mining and tunnelling, with over 15 years of hands-on experience across 8 mine sites and 7 major infrastructure tunnelling projects spanning gold, copper, zinc, lead, diamonds, coal, and civil infrastructure.

We deploy Australian-standard safety management systems, real-time production monitoring, and structured knowledge transfer programs designed to build national workforce capability from the first day of operations. We employ people from the place the mine is, and we train them on the tools, in the mine. We leave a trainer behind.

Jahkai is named for our founder's youngest son, who lives with Down syndrome. In our culture — as in yours — a name is not a brand exercise. It is a covenant. Every contract signed under this name carries the obligation to deliver work worthy of that name.

Aboriginal-owned and fully operational. The GCC and beyond.

From the first blast to the final tonne — Jahkai delivers the complete range of underground mining, tunnelling, and civil infrastructure services. Our expert teams, specialist subcontractors, and global partner network ensure every operation meets the highest international standards. We provide both integrated equipment and operator solutions (wet hire) and specified equipment supply (dry hire) across all disciplines.

Jahkai provides both fully crewed equipment packages and standalone equipment supply across all mining and tunnelling disciplines. Every wet-hire deployment includes a mandatory knowledge transfer component — we do not simply provide operators, we build your national workforce.

Equipment platforms we operate and source: Sandvik (jumbos, LHDs, trucks, roadheaders, bolters, longhole drills), Epiroc (Boomer jumbos, Scooptram LHDs, Minetruck, Boltec, surface drills), Caterpillar (R-series LHDs, AD-series trucks, rotary drills), Normet (shotcrete sprayers, charging equipment), Komatsu (surface haul trucks, hydraulic excavators), Herrenknecht (TBMs, raise borers), and Mitsui (roadheaders).

We employ people from the place the mine is, and we train them on the tools, in the mine, from offsider through operator to supervisor. We leave a trainer behind. The pathway runs from offsider through operator to supervisor, and a trainer stays after we leave.

Aboriginal Australians are the world's first miners. Wilgie Mia in Western Australia has been mined continuously for over 30,000 years — making it the oldest continuing mining operation on Earth. Aboriginal miners used underground stop-and-pillar techniques, pole scaffolding, and multi-level extraction methods tens of thousands of years before European mining began. Ochre was traded along songlines spanning 1,600 kilometres across the continent.

Our people have mined underground for thirty thousand years. We understand sovereign purpose. We understand that the land beneath your feet is not just a resource — it is a trust.
