CALGARY, June 9, 2011 /CNW/ - Madalena Ventures Inc. and its wholly owned subsidiary Madalena Austral SA ("Madalena" or the "Company"), is pleased to provide an update of drilling activity in the Neuquén basin, Argentina.

On the Curamhuele Block, the Company has completed drilling the Yapai X-1001 well to a total measured depth ("MD") of 10,743 feet (10,478 true vertical depth or "TVD") penetrating the Lower Troncoso and Avile formations.  Based on electric logs, the well encountered a potential gross hydrocarbon column of 23 feet in the Lower Troncoso formation at 4,640 feet MD (4,394 feet TVD) and as programmed the well also encountered multiple stacked Avile formations from 6,800 feet MD (6,530 feet TVD) to 10,620 feet MD (10,360 feet TVD).  The Company has elected to case the well to total depth with 7" casing and plans to test the well in several of the Avile sands and the Lower Troncoso formation in the third quarter of 2011. Two previous wells drilled on the block, Curamhuele X-1 and Yapai X-1, have been drilled into the Mulichinco formation and will be reviewed for potential re-entry to test the Vaca Muerta shale formation.

On the Coiron Amargo Block, testing of the CAS X-1 well was delayed due to poor cement across the Sierras Blancas formation.  After the completion of several remedial cement jobs, the well has tested oil up to 150 barrels per day from the Sierras Blancas formation unstimulated.  A fracture stimulation treatment of the formation will now be undertaken prior to perforation and testing of the Vaca Muerta formation at the CAS X-1 well.  Testing of the CAN X-4 well in the northern portion of the block will commence following testing at CAS X-1.  Tests of the cement at the CAN X-4 well location indicate that a good cement bond was obtained.

On the Cortadera Block, the CorS x-1 well targeting the Quintuco, Mulichinco, Vaca Muerta shale and Tordillo formations is currently drilling ahead at approximately 4,500 feet.  The Company anticipates that the well will reach TD in late July, early August 2011.

Any references in this news release to test rates, flow rates, initial and/or final raw test or production rates, early production and/or "flush" production rates are useful in confirming the presence of hydrocarbons, however, such rates are not determinative of the rates at which such wells will commence production and decline thereafter.
