Victoria Antimony Grants Boost Critical Minerals Security - Mirage News

Victoria has committed grant funding to develop antimony extraction and processing capability within the state. Antimony is classified as a critical mineral essential to defence, energy storage and electronics manufacturing. The grants are intended to reduce Australia's dependence on imported antimony and establish domestic supply chains.

Where this fits

This story touches the materials pillar of Australia's energy transition cost. Antimony is used in battery chemistry, solar panels and grid-scale storage systems. A renewables-heavy grid requires far larger stockpiles of battery materials than a firm-power grid would, and Australia's current supply chains for these materials run almost entirely through China or Chinese-controlled processors. Grants to domestic extraction are a direct response to that dependence.

What it means

Antimony development is necessary but it addresses a symptom, not the underlying problem. Australia is attempting to secure one critical mineral among dozens needed for a battery-and-solar transition. China controls refining, processing and supply chains across the full portfolio. Domestic extraction of raw ore does not solve that. A renewables-only grid amplifies the demand for these materials far beyond what a mixed firm-and-renewable system would require. Building antimony capacity is not wasted effort, but it will not close the strategic vulnerability. Australia remains dependent on China's tolerance for processing and export. A grid mix that includes firm, long-lived, low-material nuclear generation would reduce the tonnage of critical minerals the energy system must source, refine and replace every decade.
