VANCOUVER, BRITISH COLUMBIA–(Marketwired – Feb. 17, 2016) –

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 made applications for a further exploration licence in Western Australia to advance potential lithium projects.

The Company has applied for four exploration licenses covering a total area of 383 square kilometres comprised of the following projects:

• Pilgangoora Projects, in the Pilbara region of Western Australia
• Edah Hill Project, in the Mid-West of Western Australia.

Pilgangoora Projects

As announced on February 15, 2016, the Company has made applications for three exploration licences (E45/4693, E45/4694 and E45/4702 – see Figure 1) covering an area of 269 square kilometres across three project areas in the world-class Pilgangoora district, in the Pilbara region of Western Australia that are considered prospective for lithium.

Peer activity in the vicinity of the applications includes Australian Securities Exchange listed companies, Pilbara Minerals Limited and Altura Mining Limited, which have lithium projects in the region. The region is emerging as a world-class lithium district.

Edah Hill Project

The Company has made application for an exploration licence (see Figure 2) covering an area of 114 square kilometres at Edah Hill in the Mid-West of Western Australia. The Edah Hill project lies 50 kilometres east-northeast of Yalgoo in the Murchison province of Western Australia and approximately 250 kilometres from Geraldton Port.

Lithium Market

The global lithium market is growing rapidly due to developments in the technology and energy sectors, especially in the use of lithium-ion batteries for portable electronic devices, hybrid electric motor vehicles and storage battery industries.

Industry experts comment that overall lithium demand may more than double from present levels through to 2025, while incumbent producers of lithium are limited in their ability to bring on additional supply to satisfy growing demand. Industry experts further comment that lithium has been one of the few commodities to enjoy recent price appreciation, and that they expect this pattern to continue over the next 10 years.¹ The price of 99%-pure lithium carbonate imported to China more than doubled in the last 2 months to the end of December 2015, to US$13,000 a tonne.²

Global Industrial Mineral (including lithium) Exploration and Mining Experts Appointed

Complementary to the Company’s in-house mining and exploration expertise, the Company has appointed Dr Andrew Scogings and Mr Graham Jeffress from CSA Global Pty Ltd (“CSA Global”), who are Western Australia based consultants with substantial experience in the field of industrial minerals exploration, including lithium and graphite. Further details of the expertise of Dr Scogings and Mr Jeffress are contained below.

CSA Global will be initially undertaking technical evaluation of exploration targets for the Company’s lithium projects as well as supporting their development over the coming months. The Company will continue to assess and identify further opportunities for potential lithium projects.

Historical Exploration

Pilgangoora district

The broader Pilgangoora district has been the subject of extensive historical exploration for a range of minerals and is known to host many granitic pegmatites such as those discovered for the Pilbara Minerals Limited and Altura Mining Limited lithium projects. The largest concentrations of lithium- containing minerals, such as spodumene, are found in pegmatites. Due to its greater abundance, spodumene is considered the most important lithium-bearing mineral in pegmatites.

The licence areas under application have most recently been explored by Australian Securities Exchange listed Fortescue Metals Group Limited for iron, base metals and gold. Previous soil sampling in the application areas has identified pathfinder elements, such as lithium, rubidium, and caesium, typically associated with lithium-bearing pegmatites.

Edah district

The Edah district lies in the Archean granite-greenstone terrane of the Murchison Province of the Yilgarn Craton. The Edah Hill project is within an extensive area of granitic rocks between the Yalgoo Greenstone Belt (20 kilometres to the west), the Dalgaranga Greenstone Belt (20 kilometres to the north) and the Mount Magnet Greenstone Belt (50 kilometres to the east). The surrounding Murchison region contains occurrences of pegmatites with tantalum, beryl and traces of other rare metals (tin, tungsten, lithium). The most notable deposit is the high-grade Dalgaranga tantalite mine about 50 kilometres to the north.

Previous mapping of the application area and surrounding tenure reports numerous pegmatite dykes.

Follow-up exploration work on the Pilgangoora Projects and the Edah Hill Project will focus on identifying, mapping and sampling the pegmatites to confirm the presence of lithium-bearing minerals.
