McMahon Mining Title Services Report -- Macarthur Minerals Lithium Licences

Macarthur Minerals retains the services of McMahon Mining Title Services ("MMTS") to manage the Company's exploration and mining licences. As detailed in Table 1, MMTS has advised the Company that 13 out of 20 of the Company's Exploration Licence Applications ("Applications") for lithium are expected to grant by November/December 2016.

The grant of exploration licences in Western Australia requires advertisement in accordance with the Mining Act 1978 (WA) ("Mining Act") and subsequent advertisement in accordance with the Native Title Act 1993 (Cth) ("Native Title Act").

All Macarthur Minerals' Applications have been advertised in accordance with the Mining Act and no objections have been maintained. Agreements have been entered into with owners of any overlapping infrastructure leases, where required. An Access Arrangement for Application E46/1115 is currently being finalised.

The majority of Macarthur Minerals' Applications are now progressing through the Native Title Act advertising period, during which, heritage agreements will be entered into with native title parties and provided no objections are raised, are expected to grant in November/December. The remaining Applications will be advertised in the near future.

Until Exploration Licences are granted, the Company will continue prospecting activities to identify exploration targets.
