November 27, 2008

Mansfield Minerals Inc. (?Mansfield?) and Pachamama Resources Ltd. (?Pachamama?) jointly announced today that they have completed the plan of arrangement involving a spin-out by Mansfield of all of its exploration stage properties, including the Rio Grande property, and a portion of its cash and investment securities to Pachamama. 

Going forward, Mansfield will focus on the development of the Lindero property in the Salta Province of Argentina. 

The Pachamama common shares will commence trading on the TSX Venture Exchange on November 28, 2008 under the trading symbol ?PMA?. 

The share distribution record date for the purposes of determining Mansfield shareholders who are entitled to receive Pachamama common shares was the close of business on November 20, 2008.  Pachamama has made arrangements with its registrar and transfer agent to deliver share certificates representing Pachamama shares to the Mansfield shareholders of record on the share distribution record date.  No new share certificates will be issued for the new Mansfield shares issued pursuant to the plan of arrangement, therefore holders of existing Mansfield shares must retain their certificates as evidence of their ownership of the new Mansfield shares. 

Full details on the plan of arrangement are set out in the management information circular delivered to Mansfield?s shareholders in advance of the shareholders meeting held on October 29, 2008, which is available on SEDAR at www.sedar.com.
