Update on Macarthur Minerals

Rare Earth Minerals Plc (AIM: REM; OTC: REMMY)) is pleased to report that Macarthur Minerals ("Macarthur") in which REM owns a 15.5% shareholding, has announced that it has applied for an additional exploration licence in the Pilbara región of Western Australia. The full Macarthur announcement can be found at: http://web.tmxmoney.com/article.php?newsid=5529412438318408&qm_symbol=MMS .

Macarthur Minerals Limited (TSX VENTURE: MMS) (the "Company" or "Macarthur Minerals") is pleased to announce that it has applied for an additional exploration licence E45/4824, in the Pilbara region of Western Australia, adjacent to its existing exploration licences E45/4708 and E45/4709, to extend the contiguous area to 367 square kilometres (90,687 acres). The Company now has total tenement acreage under application in the Pilbara region of 1,449 square kilometres (358,055 acres), in addition to its Yalgoo, Edah Hill, Ravensthorpe, Sulphur Springs, Whim Creek interests in Western Australia and Nevada Stonewall interests in the United States of America.

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

"The Company has applied for further acreage in the Pilbara to extend exploration licence applications E45/4708 and E45/4709, with new exploration licence application E45/4824, into a contiguous area bringing the total tenement acreage under application in the Pilbara region of 1,449 square kilometres in addition to its Yalgoo, Edah Hill, Ravensthorpe, Sulphur Springs, Whim Creek and Nevada Stonewall interests. The majority of the tenement acreage under application is due to be granted by November or December, which will allow the Company to commence initial lithium exploration."

New Pilbara Tenement

The location of the new Pilbara exploration licence application (E45/4824), which covers an area of 211 square kilometres is shown in Figure 1.

The Pilbara applications cover similar geological settings to the Pilgangoora Li-Ta pegmatite deposits, which host the lithium projects of Australian Securities Exchange listed companies, Pilbara Minerals Limited and Altura Mining Limited.

Geological Setting of the Tenement Applications

Macarthur's applications in the Pilbara are selected on the basis of geological attributes that are broadly consistent with the currently accepted exploration/mineral system model for Lithium-Caesium-Tantalum ("LCT" type) rare element pegmatites. The tenement applications cover areas of potential LCT pegmatite host rocks such as greenstone belts (meta-volcanic sequences), earlier granitoids and gneisses. The tenement applications are located within 5-10 km of ~2.89 to 2.83 Ga(1) post-tectonic monzogranite (S-type) intrusions, which are considered to be the source of magmatic melts from which the LCT pegmatites evolved. The fertile character of the highly fractionated younger monzogranites(2), and their potential link to lithium mineralisation, adjacent to and within the new application is supported by numerous associated occurrences of lithium (Li), tantalum (Ta), tin (Sn), and beryllium (Be).

Acreage Package

The Company now holds 21 Exploration Licence Applications and prospective interest in rights to lithium covering a total area of 2,029 square kilometres (501,376 acres) in the Pilbara, Ravensthorpe and the Yalgoo/Edah regions of Western Australia. In addition, the Company has also entered into an agreement to acquire the Stonewall Project in Nevada, which covers an area of approximately 5,700 acres (23 km2).

Macarthur is currently evaluating its acreage and commencing discussions with various third parties concerning potential joint ventures to maximise the exploration effort throughout 2016.
