Macarthur is Awarded a Western Australia State Government Exploration Incentive Scheme Grant

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 25, 2012) -

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

Macarthur Minerals Limited (TSX:MMS)(OTCQX:MMSDF) ("the Company" or "Macarthur") is pleased to announce that it has been a successful recipient of a State Government of Western Australia Exploration Incentive Scheme ("EIS") grant. The EIS is a co-funded government-industry drilling program designed to support drilling activities, which will potentially lead to new discoveries.

Macarthur has been successful in obtaining the EIS grant for its Moonshine Project (magnetite) application. The grant provides $150,000 funding towards the Company's 2012 magnetite drilling program and the Company will supply the drill results to the Department of Mines and Petroleum for collation and eventual release to the public record.

In past years' drilling programs Macarthur encountered a high grade magnetite intersection while drilling a diamond hole to provide metallurgical samples for the Moonshine Project (magnetite). The intersection returned 12.5m at 59.3% Fe (refer to the attached press release dated August 23, 2010). It was also intercepted by 4 RC holes drilled during the 2009 and 2010 drilling programs (refer to attached press release). These RC holes were originally sampled and assayed over 5m intervals. Selected intervals were resampled and assayed at 1m intervals. Significant intervals from those results are tabulated below:

including 108 115 7 5.5 56.6 10.2 1.1 0.08 4.89

Intersections reported have been verified by the Company's QAQC protocols which are implemented in line with the standards set by National Instrument 43-101. All samples collected from drill holes were prepared by Ultra Trace and Amdel Laboratories in Perth, WA and pulverised to 90% passing 75 microns then analysed for the iron suite using XRF.

This high grade magnetite target remains untested at depth and this was the basis of the Company's EIS application. To date, Macarthur has delineated an indicated hematite resource, at a 50% cut off, of 8.6 Mt at 54.8% Fe and inferred hematite resources of 15.8 Mt at 55.4% Fe at its Ularring Project (hematite) (press release dated September 21, 2011) and it is envisaged that the high grade magnetite mineralisation zone at the Moonshine Project (magnetite) would supplement the potential direct shipping ore ("DSO"). DSO magnetite is considered the premium iron ore product.

Currently Western Australia has no reported DSO magnetite production and exploring the presence of this occurrence at depth may provide a new exploration target and iron ore production source for the Moonshine Project (magnetite).

Macarthur's President, Chairman and CEO, Mr Alan Phillips, stated that "It is very pleasing to see that the West Australian State Government recognises the exploration potential of our newly recognised magnetite target."
