Admiralty Resources Advances Mariposa Output and One Million Tonne Expansion

Admiralty Resources NL ( (AU:ADY) ) has issued an update.

Admiralty Resources reported continued ramp-up of production at its Mariposa magnetite iron ore project in Chile for the March 2026 quarter, producing 42,992 tonnes of iron ore concentrate at an average grade of 65% Fe despite a modest decline versus the prior quarter. The company shipped 58,087 tonnes of concentrate to China, completed key power infrastructure with grid connection achieved, advanced tailings, dust control, and worker facilities, and progressed drilling, transport permitting, water supply agreements, and foundation works tied to its planned one million tonne expansion, signalling steady operational growth and capacity building.

Geological drilling of 763.08 metres was completed with new rigs to be redeployed to the El Cojin copper mine, and the company plans blasting of 50,000 tonnes of waste rock to support future mine development. Ongoing regulatory engagement on the Mariposa transport environmental filing, along with negotiations for industrial water from Agrosuper and design work for the Tatara Aqueduct pipeline upon permitting, underline Admiralty’s efforts to secure the infrastructure and approvals needed to sustain larger-scale exports and strengthen its competitive position in the iron ore market.
