VANCOUVER, BC--(Marketwired - November 04, 2016) - Macarthur Minerals Limited (TSX VENTURE: MMS)

THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Macarthur Minerals Limited (TSX VENTURE: MMS) (the "Company" or "Macarthur Minerals") is pleased to announce that it has completed staking an additional 360 claims covering approximately 6,975 acres (28.22 square kilometers) surrounding its Stonewall Lithium Project ("Stonewall Project"). Expansion of the Stonewall Project, by staking additional claims, has increased the Company's footprint in the Lida Valley to a total of approximately 12,019 acres (48.64 square kilometers) covering almost all of the playa (i.e. 'dry lake bed') in the Lida Valley, Nevada. The Company has staked the additional claims because of the lithium prospectivity of the Lida Valley, indicated by surface grades returned from the initial drilling program of up to 145.5 parts per million ("ppm") lithium ("Li") 1.

The Stonewall Project is located in the Lida Valley, Nevada, the basin adjacent to the Clayton Valley, which hosts North America's only producing lithium mine, Albemarle's Silver Peak Lithium Mine.

As previously announced, lithium has been detected at the Stonewall Project from a shallow drilling program conducted as part of due diligence for acquisition of the Stonewall Project. All nine shallow drill holes reported lithium, with grades up to 145.5 ppm Li from near surface sediment, confirming that lithium is present in the Lida Valley.

David Taplin, President, CEO and Director of Macarthur Minerals commented:

"The Company has strategically expanded its footprint in the Lida Valley to cover almost all of the playa, where we have detected lithium near surface from all nine drill holes with grades up to 145.5 ppm lithium. The Company views the Lida Valley as strategic and plans to accelerate exploration. The Stonewall Project is strategically located adjacent to the Clayton Valley, where Albemarle's Silver Peak Lithium Mine, the only operating lithium mine in North America is located and 306 kilometres from Tesla's Gigafactory in Nevada."

Stonewall Lithium Project

The Company staked an additional 360 claims covering approximately 6,975 acres (28.22 square kilometers), bringing the total size of the Stonewall Project to cover approximately 12,019 acres (48.64 square kilometers), as indicated in Figure 1.

Expansion of the Stonewall Project has increased the Company's footprint in the Lida Valley to almost all of the playa, adjacent to the Clayton Valley Basin, which hosts the United States' only producing lithium mine.

As indicated in Figure 2, the Stonewall Project is strategically located in the Nevada lithium supply hub, 306 kilometers (191 miles) southeast of Tesla's new Gigafactory, which has a planned production capacity of 35 gigawatt-hours per year by 20202.

The Company's previous announcement made on October 21, 2016 contains further details of the Stonewall Project and results of the initial shallow drilling program.

Proposed ASX IPO of Australian Lithium and Iron Ore Projects

As announced on October 28, 2016, the board has resolved to progress an Australian Securities Exchange ("ASX") Initial Public Offering ("IPO") of its Australian 'hard rock' lithium and iron ore projects, subject to regulatory approval. Macarthur Minerals will maintain majority ownership and control of the ASX IPO listed entity.

The Company's wholly owned subsidiary, Macarthur Lithium Nevada Limited, will continue to advance the Stonewall Lithium Project, located in Nevada.

Australian 'Hard Rock' Lithium Projects

The Company has one of the largest lithium hard rock acreage packages in Australia, covering an area of 2,029 square kilometres (501,376 acres) across the Pilbara, Ravensthorpe and the Yalgoo/Edah regions of Western Australia. Initial reconnaissance across the Company's acreage has been encouraging, including initial assay results from rock chips of up to 3.75% lithium (Li2O) received at the Yalgoo Lithium Project (see the Company's announcement dated October 12, 2016).

Australian Iron Ore Projects

The Company owns the Ularring Hematite and the Moonshine Magnetite Projects in the Yilgarn region of Western Australia. The Company has previously invested over A$60 million in progressing the Ularring Hematite Project beyond Pre-Feasibility3 and the Moonshine Magnetite Project to a Preliminary Economic Assessment4. The Ularring Hematite Project has received approval to develop an iron ore mine under Western Australian and Australian Federal environmental laws.

The Company believes that the iron ore projects remain valuable assets with the recovery of the global iron ore market, with a spot price of $US65.46 a tonne today5.
