Sierra Minerals Forms Strategic Review Committee

Rejects Treasury Metals Proposal As Inadequate

TORONTO, ONTARIO--(Marketwire - March 5, 2009) - Sierra Minerals Inc. (TSX:SIM) ("Sierra" or the "Company") announces that its Board of Directors unanimously approved the formation of a Strategic Review Committee comprised of three independent directors. The committee is comprised of Donald Goldman (Chairman), Bill Cavalluzzo and Julian Kemp. The Committee's purpose is to evaluate and make recommendations to the full Board of Directors on mergers and acquisition opportunities presented to the Company by various parties and opportunities identified internally by the Company's management. The committee's mandate is to identify, review and recommend opportunities that create superior shareholder value in relation to the Company's current operating plans and organic growth initiatives.

Management of Sierra and members of the Strategic Review Committee of the Board of Directors met with the management of Treasury Metals Inc. ("Treasury") and reviewed the merits of the proposal put forth by Treasury (see news release dated February 2, 2009). The Board of Directors reports that it has unanimously rejected the proposal as inadequate and determined that the proposal is not fair from a financial point of view to the shareholders of Sierra or in the best interests of Sierra.

With the receipt of a substantial portion of the recently announced non-brokered private placement (see news release dated February 27, 2009), the Company believes that it continues to create immediate and sustainable value.
