Southern Arc Directs Investors to Eagle Hill Exploration's Preliminary Economic Assessment Technical Report

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jun 11, 2015) - Southern Arc Minerals Inc. (TSX VENTURE:SA) ("Southern Arc" or the "Company") is pleased to announce that Eagle Hill Exploration Corp. (TSX VENTURE:EAG) ("Eagle Hill") has filed on SEDAR the National Instrument 43-101 technical report for the Preliminary Economic Assessment ("PEA") for Eagle Hill's 100%-owned Windfall Lake Gold Project ("Windfall Lake" or the "Project") in Quebec, Canada. Southern Arc owns 26.25% of Eagle Hill.

Highlights of the Windfall Lake PEA are summarized below. Additional information is available in Eagle Hill's press release dated April 28, 2015. The entire technical report is available for download on Southern Arc's website at www.southernarcminerals.com and on SEDAR at www.SEDAR.com. All figures are quoted in Canadian dollars unless otherwise noted.

The PEA outlines the design of a 1,200 tonne per day ("tpd") underground mine producing 106,200 ounces of payable gold annually for 7.8 years at an average total cash cost of $558/oz of gold (US$480/oz). At the base case gold price of US$1,200/oz the project has a pre-tax internal rate of return ("IRR") of 23.6% and a net present value discounted at 5% ("NPV₅") of $241.4 million (post-tax 17.2% and $135.2 million). At a gold price of US$1,320/oz the pre-tax IRR and NPV₅ increase to 29.1% and $325.9 million, respectively (post-tax 21.1% and $183.5 million) and at a gold price of US$1,440/oz the pre-tax IRR and NPV₅ increase to 34.4% and $410.5 million, respectively (post-tax 24.8% and $230.1 million). Initial project capital costs are estimated at $240.6 million. Project economics are most sensitive to the exchange rate and gold price and least sensitive to operating costs.

PEA Highlights ⁽¹⁾

The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no certainty the results of the PEA will be realized.

The PEA was led by TetraTech Inc.'s Canadian Mining Division (mine design, infrastructure and financial analysis), with contributions from Soutex Inc. (metallurgy and mill trade-off study), Golder & Associates Ltd. (environmental), WSP Global Inc. (tailings evaluation) and SRK Consulting (Canada), Inc. (mineral resource estimate).

Eagle Hill and the PEA consultants have identified a number of opportunities to optimize the project, including the possibility of reducing operating costs by bringing hydro power to site, improving project economics by incorporating silver credits, and the potential to both expand and upgrade the resource with additional drilling.

"As a significant investor in Eagle Hill, Southern Arc's Board of Directors was very encouraged with the outcome of the Windfall Lake PEA," said John Proust, Chairman and CEO of Southern Arc. "We believe Windfall Lake to be one of the most promising development-stage projects in Canada, with good upside potential for Southern Arc's shareholders.

"On June 9th Eagle Hill announced a proposed transaction that would see Eagle Hill combine with Oban Mining, Temex Resources, Ryan Gold and Corona Gold to create a new leading Canadian focused gold exploration and development company. Our support for that transaction was based, in part, on Oban's intention to continue advancing the Windfall Lake Project through feasibility and toward production."
