CALGARY, April 4, 2012 /CNW/ - Madalena Ventures Inc. and its wholly owned subsidiary Madalena Austral SA ("Madalena" or the "Company"), have commented today on press announcements in Argentina that certain blocks held by other operators in the Province of Neuquen have been revoked due to a lack of investment.  As previously reported the Company has met or exceeded the work requirements specified on all three of its exploration blocks and has recently agreed with the Province forward plans for each block which the Company is actively pursuing as part of its 2012 drilling programs.  Under the terms of the various agreements, the northern 108 km² of the 404 km² Coiron Amargo Block was recently converted by the Province to a 25 year exploitation concession. In addition, the exploration period for the remainder of the Coiron Amargo Block and the Curamhuele Block was extended to November 8, 2013.
