Petrominerales Corcel-E1 Well Produces 4,900 bopd

Petrominerales Ltd. ("Petrominerales" or the "Company") (TSX:PMG), a 66.8% owned subsidiary of Petrobank Energy and Resources Ltd. ("Petrobank") (TSX:PBG), is pleased to announce that our Corcel-E1 well is producing 4,900 barrels of 17 degree API oil per day, at less than 1% water cut, following a successful completion in the Lower Sand 1 formation. The well was spud on March 18, 2009 and drilled directionally, reaching a total depth 12,614 feet on May 3, 2009. Well logs indicated total net pay of 113 feet, consisting of 48 feet in the Lower Sand 1 and 65 feet in the Mirador and Guadalupe formations. We have run an electric submersible pump and plan to initially produce Corcel-E1 from the Lower Sand 1 formation alone. The Guadalupe and Mirador formations are the main producing horizons at Corcel and these zones will be completed and evaluated in Corcel-E1 sometime in the future. Including Corcel-E1, total Company production is currently above 25,000 bopd.

Corcel-F1 has been drilled to a depth of 11,926 feet and we are preparing to run intermediate casing to the top of the Mirador formation. We expect to have the zones of interest logged by mid-June. We then plan to spud the next well in our ongoing Corcel drilling program, Corcel-B1, by the end of June.

We are also mobilizing a drilling rig to our Chiguiro Este exploration block and plan to spud Chiguiro Este-1, the first well in our 2009 three-well heavy oil exploration program, during the first week of June.

Phase 1 construction of our Monterrey offloading station with a delivery capacity of 11,000 bopd is now complete. We are finalizing facility commissioning and expect to commence deliveries the first week of June. Final delivery capacity of 20,000 bopd is expected to be available early in the third quarter of this year. The facility will be the closest offloading station to Corcel, 77 kilometers away, and will significantly reduce our trucking costs for volumes delivered to Monterrey.
