Amara Minerals Limited has filed a cross-claim in the Supreme Court of New South Wales against Great Divide Mining Limited and Challenger Mines Pty Ltd, seeking court declarations to unwind settlement transaction documents entered into in December 2025.

The legal action follows proceedings commenced against Amara by Great Divide Mining in May 2026, which seek to enforce an indemnity relating to a goods and services tax liability assessed by the Australian Taxation Office against Challenger Mines.

In the newly filed cross-claim, Amara alleges that Great Divide Mining made representations that were likely to be misleading or deceptive in connection with the resolution of an earlier dispute between the parties, leading Amara to enter into the December 2025 settlement agreements. Alternatively, Amara claims that Challenger Mines should be held liable to contribute 50 per cent of any amount that Amara is required to pay under the disputed indemnity.

Amara continues to deny liability to indemnify Great Divide Mining in respect of the tax assessment and intends to defend the primary claim.

The Supreme Court granted Amara leave to file the cross-claim on 28 August 2026, with formal orders entered on 31 August 2026. This procedural step does not constitute a determination on the merits of the allegations, which remain untested.

Under the current court timetable, Amara is required to serve its lay evidence in support of the cross-claim by 25 September 2026. The proceedings are scheduled to return to the Court for directions on 2 October 2026, while a trial date has not yet been allocated.
