TORONTO, April 28, 2014 /PRNewswire/ - Augusta Resource Corporation (TSX and NYSE MKT: AZC) ("Augusta" or the "Company") demonstrated today that it is committed to maximizing shareholder value by continuing to aggressively pursue strategic alternatives and ensuring its value-enhancing process is comprehensive and complete, even if the offer for Augusta shares by HudBay Minerals Inc. ("HudBay") expires or is terminated.

Augusta's shareholder rights plan permits Augusta to continue to pursue strategic alternatives by preventing HudBay from acquiring a blocking position that would permit HudBay to veto any alternative transactions with other parties.  Augusta has asked its shareholders to approve the continuance of the shareholder rights plan at the annual and special meeting on May 2, 2014. 

If shareholders, other than HudBay, do not approve the continuance of the rights plan at the shareholder meeting, the rights plan will be terminated prior to the expiry of HudBay's offer on May 5, 2014. 

If shareholders approve the continuation of the rights plan and the British Columbia Securities Commission determines to respect that approval, the Board of Directors of Augusta has determined that Augusta will not utilize the rights plan to prevent any unsolicited bidder, including HudBay, from acquiring Augusta shares if holders of a majority of the Augusta shares (other than the bidder) desire to accept the bid.  Accordingly, the Board has determined that it will waive or terminate the rights plan to permit any bidder to take up Augusta shares tendered to its bid if (a) at the relevant time the bid, or any variations thereto, has been outstanding for at least 60 days (which is now the case with the HudBay offer), (b) more than 50% of the outstanding Augusta shares held by shareholders, excluding shares held by the bidder or its affiliates, associates or joint actors, are tendered to the bid and not withdrawn on the date of expiry of the bid, and (c) the bidder has made public announcement of this fact and extended the bid for not less than 10 business days from the date of such announcement in order to allow other shareholders to tender to the bid if they choose to do so. 

"We believe that the future of our Company should be decided by a fair process to both protect the rights and determine the wishes of our shareholders, whether through tenders to a bid or a vote at a meeting of shareholders," Gil Clausen, Augusta's President and CEO, stated. "Our shareholder rights plan is intended to facilitate this and was never intended to permit the Board to 'just say no' to HudBay or any other unsolicited bidder.  We are fully committed to rigorously pursuing strategic options to provide our shareholders maximum value for their shares, even if HudBay's offer disappears."

Vote For Continuation of Shareholder Rights Plan
Shareholders are reminded to submit their proxies for the annual and special shareholders meeting on May 2, 2014 and to vote FOR the continuation of the shareholder rights plan prior to April 29, 2014, the date scheduled for the British Columbia Securities Commission hearing on the rights plan so that their proxy votes can be considered.
