Nova secures refinery land, signaling progress toward 2026/27 antimony output.

The filing indicates that Nova Minerals Limited has secured land use for an antimony refinery at Port MacKenzie and is targeting production of military-spec antimony in 2026/27. This suggests movement from exploration or upstream activities toward establishing refining infrastructure capable of producing specialized antimony products.

The reference to military-spec antimony points to a focus on higher-specification, potentially defense-related end markets, which often require stringent quality and supply assurances. However, the excerpt does not provide capital cost, capacity, funding details, or regulatory status, so the scale and economics of the refinery are not clear from this information alone.

Future company disclosures covering project financing, construction progress, and any permits tied to the Port MacKenzie site will be important to understand how quickly Nova can move from securing land use to actual commissioning of military-spec antimony production targeted for 2026/27.
