Macro Metals has increased its landholding in Western Australia's Pilbara region by applying for 25 new exploration licences, covering a total area of 749km2.
The new tenure includes a diverse range of targets, from high-grade surface mineralisation identified through rock chip sampling to conceptual targets based on mapping and geophysics.
The expanded asset portfolio is expected to provide a substantial pipeline of exploration and development targets.
The new acquisitions aim to enhance material scale, diversify logistics pathways, and extend product specifications.
The Bungaroo North Project, adjacent to Rio Tinto's (ASX:RIO) Bungaroo Creek, reported iron grades of up to 64.18% Fe through surface samples.
Managing Director Simon Rushton stated, "The board and I remain steadfast in our vision and commitment to successfully building a sustainable, diversified mining and mining services business."
The Six Mile Well Project, located near Rio Tinto's Mesa J operations, reported multiple channel iron mineralisation samples with grades as high as 63.51% Fe.
Meanwhile, the Nammuldi North Project, adjacent to Rio Tinto's Nammuldi open iron ore pit, features two zones of goethite mineralisation.
Rob Jewson, technical executive director, commented, "Bungaroo North has the potential to be a very high-grade valley fill CID/DID drill target that warrants immediate sampling and mapping to define the surface extent of mineralisation."
Macro Metals' technical team has commenced the prioritising and ranking process for these newly acquired targets, which will inform the future schedule of exploration programs.
The company aims to apply for bulk sample permits soon, intending to maximise the size of the bulk samples produced and exported to prospective overseas customers.
