    TSX.V: PEG

    VANCOUVER, July 16 /CNW/ - Petro Rubiales Energy Corp. (the "Company" or
"Petro Rubiales") is pleased to announce that it has closed its previously
announced private placement of 517,650,000 units (the "Units") at a price of
C$0.85 per Unit (the "Financing") for gross proceeds of C$440,002,500. The
Company has also completed its acquisition of 75 percent of the outstanding
shares of Rubiales Holdings Limited ("RHL") and has changed its name from
Consolidated AGX Resources Corp. to Petro Rubiales Energy Corp., effective
July 13, 2007.
    The Private Placement, led by GMP Securities LP with a syndicate
including Canaccord Capital Corporation., Orion Securities Inc., and Fraser
Mackenzie Limited, closed into escrow on July 12, 2007 and on completion of
the acquisition of 75 percent of the outstanding shares of RHL, effective
July 16, 2007, the funds were released from escrow. Each Unit consists of one
common share and one-half of a share purchase warrant. Each whole share
purchase warrant entitles the holder to acquire one additional common share at
an exercise price of C$1.30 per common share until July 12, 2012. All
securities issued pursuant to the private placement will be subject to a four
month hold period, expiring November 13, 2007.
    The vendors of 75 percent of the outstanding shares of RHL received a
total of US$245,000,000 in cash and 12,701,176 Units with a four month hold
period, expiring November 17, 2007. At closing, German Efromovich, one of the
vendors, along with a family member holds the remaining 25 percent interest in
RHL. Mr. Efromovich was appointed to the board of directors, effective,
July 16, 2007.
    The proceeds of the Financing will be used by the Company to fund the
Rubiales acquisition, the acquisition of Major International Oil S.A and for
ongoing exploration and development of its heavy crude oil operations in
    RHL owns 100 percent of Meta Petroleum Limited ("MPL"), a premier oil and
gas operator, with assets in the Llanos Basin in the Meta Department of
Colombia. Through its wholly-owned subsidiary MPL, RHL holds indirect interest
in three hydrocarbon properties with Ecopetrol S.A, the Colombian, state-owned
oil company, including; the Rubiales, Piriri and Quifa Blocks. MPL currently
produces more than 18,500 gross (5,000 net) barrels of heavy crude oil (12.5
degree API) per day from its Rubiales and Piriri association contracts. Based
on a report by Petrotech Engineering Ltd. dated, May 31, 2007 (the "Petrotech
Report") prepared in accordance with National Instrument 51-101 (Standards of
Disclosure for Oil and Gas Activities) the Rubiales Field contains proven,
probable and possible reserves of 328.4 million barrels of heavy crude oil.
The Petrotech Report is available for review under Petro Rubiales' profile at
    In order to increase the heavy crude oil production rate to 66,000
barrels of oil per day in the proved and probable reserve category at the
Rubiales and Piriri Blocks, new horizontal and vertical wells are to be
drilled in a form of clusters, each cluster consisting of one vertical and
four to five horizontal wells with downhole electrical submergible pumps for
each well. To further increase the production rate to over 126,000 barrels of
oil per day at the Rubiales and Piriri Blocks, more clusters will be drilled
with an estimated 200 new wells required for the total development.
    In order to reduce the transportation cost of the increased production of
heavy crude oil from the Rubiales Field, a pipeline will need to be built
between the Rubiales Field and the Cusiana Station, located in the Casanare
Department of Colombia. The pipeline will be operated by MPL and is a joint
operation between MPL and Ecopetrol S.A. The preliminary engineering design
for the pipeline was completed by Procesos y Disenos Energeticos S.A., a
subsidiary of Mustang Engineering of Houston, Texas, USA. The proposed
pipeline will have a maximum flow capacity of 200,000 barrels of oil per day
and will be 215km in length. The anticipated completion date of the pipeline
is June 2009.
    In respect of the Quifa Block, the Company has entered into a Memorandum
of Understanding with Pacific Stratus Energy Ltd. ("Pacific") which grants
Pacific an option to earn up to 50 percent in the interests of the Company to
the Quifa Property, by funding the Company's share of costs and expenses
during the exploration phase of the project, at an estimated cost of
    GMP Securities LP and Endeavour Financial Ltd. were paid advisory fees
upon closing of the Rubiales acquisition of US$3,825,000 through the issuance
of 4,858,000 Units, with similar terms to those in the Financing and a four
month hold period, expiring November 17, 2007. The advisory fee of
US$4,000,000 payable to Aventia Ltd. was paid in cash.
    The US$15,000,000 bridge loan provided to the Company by Endeavour Mining
Capital Corp ("EMCC") has been repaid. As consideration for providing the
bridge loan, EMCC received 4,000,000 warrants exercisable for one common share
of the Company at a price of C$1.05, expiring May 24, 2008.
    The Board of Directors of Petro Rubiales now consists of Ronald Pantin,
