Australian cobalt supply 2026: what the DRC export quota means for exploration

Tuesday 30 June 2026

The Democratic Republic of Congo has drawn a line through global cobalt supply. The country's 2026 export quota caps shipments at 96,600 tonnes, split between 87,000 tonnes allocated to existing producers and 9,600 tonnes held as a strategic government reserve. In 2024, the DRC produced roughly 204,000 tonnes, meaning the quota removes more than half of the world's largest cobalt source from international markets almost overnight. The projected market deficit for 2026 is 10,700 tonnes.

For Australia, a country with known cobalt deposits and an active critical minerals strategy, the implications are both geological and commercial.

Classification and geological origin

Cobalt (Co, atomic number 27) is classified as both a critical mineral and a battery metal. Its primary industrial applications include lithium-ion battery cathodes (particularly NMC chemistry, where cobalt provides thermal stability and energy density), nickel-based superalloys for jet engines and gas turbines, and samarium-cobalt permanent magnets used in defence and aerospace systems.

Cobalt rarely occurs as a primary ore target. It is almost always recovered as a by-product or co-product of nickel or copper mining. The main ore deposit types are lateritic nickel-cobalt deposits, where cobalt concentrates in limonite and saprolite zones during tropical weathering of ultramafic rocks; sediment-hosted stratiform copper-cobalt deposits, the dominant model in the DRC's Copperbelt; hydrothermal vein-hosted deposits; and volcanogenic massive sulphide (VMS) systems, where cobalt occurs alongside copper and zinc.

The geological distinction matters commercially. Lateritic deposits, which dominate Australia's cobalt endowment, require hydrometallurgical processing (high-pressure acid leach or atmospheric leach circuits), while the DRC's stratiform deposits are processed through conventional pyrometallurgical routes. The two processing pathways demand fundamentally different engineering and metallurgical expertise.

Australian deposits and active programs

Australia's cobalt resources are concentrated in two main geological settings.

In Western Australia, the Murrin Murrin operation (operated by @Minara Resources, a subsidiary of @Glencore) has produced cobalt as a by-product of nickel from lateritic ores since 1999. The operation's high-pressure acid leach (HPAL) circuit was one of the first commercial-scale laterite processing plants in the world, and its operational history provides a technical reference point for subsequent Australian laterite projects. Broader nickel-cobalt laterite exploration continues across the Eastern Goldfields and other ultramafic-hosted terranes in WA.

In New South Wales, the Sunrise project (formerly Clean TeQ, now held by @Sunrise Energy Metals) hosts one of the largest undeveloped cobalt-nickel-scandium deposits outside the DRC. Located near Fifield in central-western NSW, Sunrise's lateritic mineralisation sits in a weathered ultramafic complex, and the project's development pathway hinges on ion exchange processing technology rather than conventional HPAL.

Broken Hill in western NSW also hosts cobalt mineralisation within its polymetallic mineral system, though cobalt has historically been a minor component relative to lead, zinc, and silver.

As DRC supply tightens, these Australian projects gain strategic significance that their standalone economics may not have supported in a surplus market. The cobalt price signal, with hydroxide at US$25.53 per pound as of mid-June 2026, will determine how quickly feasibility studies accelerate.

Why this matters for batteries, defence, and decarbonisation

Global cobalt demand is projected at 292,300 tonnes for 2026, driven primarily by the electric vehicle battery sector. NMC cathode chemistry, which uses cobalt to improve thermal stability and cycle life, remains the dominant formulation for premium EV batteries despite ongoing efforts to develop cobalt-free alternatives such as LFP (lithium iron phosphate).

The DRC quota creates a structural problem that demand-side chemistry shifts cannot solve quickly. Even with Indonesian nickel-cobalt laterite operations ramping production, the timeline to replace 100,000-plus tonnes of annual DRC supply is measured in years, constrained by processing plant construction, environmental permitting, and workforce development.

For defence applications, cobalt's role in superalloys and permanent magnets makes supply security a sovereign concern. Australia's critical minerals strategy explicitly identifies cobalt as a priority element, and the DRC's willingness to use export quotas as a policy instrument reinforces the case for domestic supply chain development.

The talent demand link

The workforce implications are immediate and specific. Cobalt-bearing lateritic ores require different geological and metallurgical skill sets from conventional base metal or gold deposits. Field geologists working laterite programs need familiarity with regolith profiling, limonite-saprolite boundary identification, and the geochemical sampling protocols that define cobalt distribution within weathered ultramafic sequences.

On the processing side, hydrometallurgical expertise, particularly in HPAL and ion exchange circuits, is a specialised discipline with a limited talent pool in Australia. As projects like Sunrise move toward development decisions and new laterite targets enter the exploration pipeline across WA, the competition for experienced laterite geologists and hydromet engineers will intensify.

At Norwest Exploration and Mining Services, we specialise in rapid deployment of geologists and field technicians into active programs across Australia, including programs targeting cobalt-bearing mineralisation as either a primary commodity or a by-product credit.

The DRC has demonstrated it will use supply control as a policy lever. Whether Australia can convert its geological cobalt endowment into a functioning, investable supply chain depends on capital allocation, processing technology, and the availability of experienced field teams to do the work on the ground.
