PERTH, AUSTRALIA--(Marketwired - June 15, 2017) -

THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE U.S.

Western Areas Ltd. (ASX:WSA) "Western Areas" or the "Company") is pleased to announce that the Company has trebled the defined high grade Massive Sulphide Mineral Resource at the Cosmos Odysseus Project ("Project" or "Odysseus"). A significant percentage of the Disseminated Inferred Mineral Resource at the Project has also been upgraded to the Indicated category providing increased confidence and flexibility in the Definitive Feasibility Study that is currently underway.

Key highlights from the Mineral Resource update include:

• A 311% increase in the Total Massive Sulphide Resource to 22,838 nickel tonnes grading 8.4% Ni which now includes 8,836 nickel tonnes grading 6.1% Ni in the Indicated category;
• A 78% increase in the Odysseus North disseminated Indicated Resource to 81,156 nickel tonnes grading 2.6% Ni (previously 45,519 nickel tonnes grading 2.8% Ni);
• An overall increase in the Indicated to Inferred disseminated resource ratio from 77% to 94%, which includes a ratio increase of 56% to 93% in Odysseus North disseminated;
• The increase in Indicated Resource provides greater flexibility to the proposed mine design and schedule of the Definitive Feasibility Study; and
• The Total Odysseus Mineral Resource Estimate now stands at 7.9Mt @ 2.5% Ni for 199,174 nickel tonnes at a cut-off of 1.5% Ni.

Western Areas Managing Director, Dan Lougher, said that it was pleasing to tick off another milestone for the Odysseus Project at Cosmos.

"The increase in the confidence level of the resources at Odysseus was one of the critical path items for the timely completion of the project DFS, and will support the definition of an Ore Reserve for the project. The amount of massive sulphides included from limited drilling and the increase in total nickel tonnes was above our expectation when we completed due diligence on this acquisition," Mr Lougher said.

"We are also pleased to advise that Piran Mining has been appointed as Project Manager for the DFS and has already commenced work. Piran Mining was Project Manager for the Spotted Quoll feasibility study which has turned into one of the great success stories for underground mining in Western Australia. Piran is well versed in the quality controls and high technical expectations driven by the Western Areas team, which was an important factor in making this appointment," Mr Lougher said.
