Almaden Minerals Ltd. Announces the Adoption of Shareholder Rights Plan

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/19/11 -- The Board of Directors (the 'Board') of Almaden Minerals Ltd. (TSX: AMM)(NYSE Amex: AAU) (the 'Company') has adopted, subject to any NYSE Amex acceptance or approval as may be required, a shareholder rights plan (the 'Plan'). The TSX has given conditional approval to the Plan.

The Plan is not intended to prevent takeover bids for the Company, to secure continuance of current management or the directors in office or to deter fair offers for the Company's shares. The Plan will provide the Board and the shareholders with more time to fully consider any unsolicited takeover bids for the Company without any undue pressure, it will allow the Board to pursue other alternatives to maximize shareholder value, and it will allow additional time for competing bids to emerge. The Plan will protect the Company's shareholders from unfair, abusive or coercive takeover strategies, including the acquisition of control of the Company through a takeover bid that does not treat all shareholders equally of fairly.

To implement the Plan, the Board authorized the issue, on April 13, 2011, of one right in respect of each common share outstanding to the holder of record at 5:00 p.m. ( Vancouver time) on April 13, 2011. The rights will trade with common shares and be represented by certificates representing common shares.

On the occurrence of certain triggering events, including the acquisition by a person or group of 20% or more of the votes attached to all outstanding voting shares of the Company in a transaction not approved by the Board, the rights will entitle the holders (other than the acquiring person or group) to acquire shares of the Company at a discount to the market price.

The Board may, at its option, exchange all or any part of the outstanding rights for common shares at a ratio of one common share per right.

The rights are not triggered by purchases of voting shares made pursuant to a permitted bid, a takeover bid made to all holders of common shares on identical terms. A permitted bid must be made by way of a takeover bid circular prepared in compliance with applicable securities laws and must comply with certain other conditions including the requirement that it must be open for at least 60 days and more than 50% of the common shares (other than shares beneficially owned by the offeror and certain related parties) must be deposited under the bid and not withdrawn before any shares may be taken up and paid for and, if 50% of the common shares are so deposited and not withdrawn, an announcement of such fact must be made and the bid must remain open for a further ten business days.

Although the Plan is effective upon its adoption, in accordance with stock exchange requirements it will be submitted to the shareholder of the Company for confirmation at the next annual meeting to be held no later than August 28, 2011 and thereafter at every 3rd annual meeting.

A copy of the Plan has been filed on SEDAR and is available for viewing on the Company's website at www.almadenminerals.com.
