Augusta Preserves Shareholder Choice

- Advances Shareholder Meeting to May 2 -

TORONTO, April 8, 2014 /PRNewswire/ - Augusta Resource Corporation (TSX and NYSE MKT: AZC) ("Augusta" or the "Company") announced that it has advanced to May 2, 2014 the date of its previously scheduled annual and special shareholder meeting to re-affirm the continuance of its shareholder rights plan.  The advancement of the shareholder meeting to a date prior to the expiry of the unsolicited offer for Augusta common shares by HudBay Minerals Inc. ("HudBay") preserves the ability of Augusta's shareholders to decide whether they wish the rights plan to continue to prevent HudBay from gaining a minority blocking position in the shares of Augusta.

Following the March 28, 2014 announcement of Augusta's shareholder meeting to re-affirm the continuance of the rights plan, HudBay extended the expiry of its offer to a date just four days prior to the date initially scheduled.  HudBay also announced that this was the "final extension" of its offer and that it will be applying to the British Columbia Securities Commission to cease trade Augusta's rights plan prior to the expiry of its offer.  This was a clear and deliberate tactical attempt by HudBay to deny Augusta's shareholders of their ability to make one of the most critical decisions in respect of their investment in Augusta.  Augusta will vigorously defend the shareholder rights plan at any hearing that may be called.

"HudBay's tactics are transparent and clearly focused on denying Augusta shareholders value for their shares," Gil Clausen, Augusta's President and Chief Executive Officer, stated. "First, HudBay used the unprecedented tactic of dropping its minimum tender condition part way through its initial bid period to coerce our shareholders.  Now, HudBay is attempting to deny our shareholders their critical vote on the rights plan by manipulating the timing of its offer. The future of our Company should be decided by a fair and non-coercive shareholder vote.  For this reason, we are putting the power of this important decision directly in the hands of Augusta shareholders.  Our Board takes its duties seriously and we will continue to protect the interests of our shareholders."

While the rights plan remains in effect, HudBay, or any other party, can make a "permitted bid" under the rights plan without triggering the plan.  A permitted bid would allow Augusta's shareholders to decide whether the bid is acceptable to them in a non-coercive manner, as the permitted bid must contain an irrevocable minimum tender condition of a majority of shares held by shareholders other than the bidder.  The Company remains fully focused and committed to maximizing value for its shareholders by carefully considering all available alternatives to HudBay's offer.

If shareholders, other than HudBay, approve the rights plan at the meeting, on an annual basis thereafter, shareholders will be given the opportunity at each annual meeting to determine whether to continue the rights plan or require the Board to have it terminated.  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.   The proxy circular and related materials to the shareholder meeting will be filed and distributed to shareholders today.

Reject HudBay's Offer – No Action Required
To REJECT HudBay's offer no action is required on the part of shareholders. The Board of Directors' recommendation that Augusta shareholders REJECT HudBay's unsolicited offer and NOT TENDER their Augusta shares thereto, as well as a more detailed discussion of the reasons for rejecting HudBay's offer is set forth in the Directors' Circular issued by the Board of Directors that was mailed to Augusta's shareholders and filed with securities regulatory authorities.  Shareholders are advised to read the Directors' Circular carefully and in its entirety, as it contains important information regarding Augusta, HudBay and HudBay's offer.  The Directors' Circular is available on SEDAR at www.sedar.com and on Augusta's website at www.augustaresource.com.
