Matsa officials, which inked the processing deal with AngloGold in late May, sent the haul on July 25 and will now deliver regular ore under a five-year ore purchase agreement with the miner.

There will be plenty of capacity for Red October's ore at Sunrise Dam; the plant, located at the Sunrise Dam gold mine, is a 3.8-million-tonne-per-year mill. It is located 10km from Red October, and the haulage route between the two is owned and maintained primarily by Matsa.

Additionally, Matsa has previously delivered ore from its Fortitude and Red Dog gold operations to Sunrise Dam.

Matsa executive chairman Paul Poli said the delivery is a significant milestone for the miner.

"It is expected that this will be the start of regular, continuous ore deliveries to Sunrise Dam for the foreseeable future, generating a regular income stream in the process," he said.

"We remain committed and are confident that we can build a long-term profitable mine at Red October."

Red October, which has open-pit and underground components, is located in the Laverton Greenstone Belt (LGB).
