Macarthur Minerals Announces Update on Iron Ore Projects and Private Placement

VANCOUVER, Aug. 21, 2017 - Macarthur Minerals Limited (TSX-V:MMS) (the “Company” or “Macarthur Minerals”) is pleased to announce that it is in discussions with parties for options for moving the Company’s iron ore projects forward. The Company has also extended closing for Tranche 2 of the non-brokered private placement.

Macarthur Mineral’s President, Director and CEO, David Taplin commented that, “We are in discussions with parties for options for moving our iron ore projects forward. These parties are particularly interested in our low CAPEX hematite project with an iron ore price today of US$78 per tonne. Our hematite project is located 80 kilometers from Cleveland Cliffs’ existing iron ore transport infrastructure that export iron ore out of the Port of Esperance.”


Iron Ore Projects

The Company owns two iron ore projects; the Ularring Hematite Project and the Moonshine Magnetite Project. These projects are co-located on contiguous granted Mining Leases in the Yilgarn Region of Western Australia. The region is a well-established mining district with two existing iron ore producers, one being a global producer. The region is well serviced with infrastructure including iron ore export facilities at the Port of Esperance.

The Company has previously expended approximately $61 million in exploration, metallurgical test-work, mining studies and environmental surveys on its Iron Ore Projects.

The Ularring Hematite Project’s Mineral Resources are comprised of Indicated Mineral Resources of approximately 54.5 Mt @ 47.2% Fe and approximately 26Mt @ 45.4% Fe Inferred resources. The Mineral Resource estimates were prepared by CSA Global on behalf of Macarthur Minerals (N143-101 Technical Report, 20121) and reported in accordance with the JORC Code.

The Company has received approval to develop an iron ore mine for the Ularring Hematite Project and associated infrastructure at the project location under the Environmental Protection Act 1986 and the Environmental and Biodiversity Conservation Act 1999.

The Inferred Mineral Resource estimate for the Moonshine Magnetite Project was initially prepared by CSA Global Pty Ltd (NI 43-101 Technical Report, 20092) and was updated by Snowden Mining Industry Consultants in 2011 (NI 43-101 Technical Report, 20113). The Moonshine Magnetite Project has an Inferred Mineral Resource consisting of approximately 1,316 Mt @ 30.1% Fe.

A Preliminary Assessment Report was prepared on the Moonshine Magnetite Project by Snowden Mining Industry Consultants in 2011.

To date, Macarthur Minerals has issued 1,705,690 units (each, a “Unit”) and 830,110 shares for a total of $135,091 under Tranche 2 of the Offering.
