For immediate release

24 February 2006


                            Black Rock Oil & Gas PLC

                        ("Black Rock" or the "Company")

       Update on proposed steam testing of the Acre Oil Field in Colombia


Field Update


The Board of Black Rock Oil is pleased to announce that during a visit to
Colombia this week by the Chairman and Managing Director of the Company,
agreement has been reached with the Company's Colombian joint venture partner,
Kappa Resources Colombia Limited ("Kappa"), for the completion by their joint
venture of the Arce 2 Appraisal Well as part of the preparations for conducting
a steam test of the Arce Oil Field in the Las Quinchas Block, Middle Magdalena
Basin, Colombia.


As previously announced in April 2005, the Company acquired a 50 per cent.
non-operated equity interest from Kappa in the 249,000 acre Las Quinchas
Association Contract located in the prolific Middle Magdalena Valley of Colombia
. The Company and Kappa have agreed that their joint venture will commence
steaming the Arce Oil Field, once manufacture of equipment has been completed in
California, USA and transported to location.


As set out in the Company's Annual Report and Accounts for the year ended 30
June 2005, the Board of Black Rock anticipates that the Arce Oil Field,
estimated to contain gross recoverable oil reserves of 5 million barrels, could
be in commercial production during 2006.  Should these operations prove
successful, further production wells will be drilled into the field to increase
the daily production rate.


Black Rock and Kappa have also agreed to re-enter the Baul Well which was
previously on commercial production but shut-in in 1961 due to the then
prevailing low oil price.  If the Baul Well is in good condition, it will be
tested with a view to declaring commerciality during 2006.


Ivan Burgess, Managing Director of Black Rock Oil & Gas plc, commented:


"This represents the first stage of our active development, appraisal and
exploration programme in 2006. If successful, the Arce steam flood project
should start to generate cash flow for the Company later this year, which would
be another strategic milestone for Black Rock."


Qualified Person and other matters


Dr John Cubitt (a Director of the Company) has been involved in the oil and gas
production for more than 26 years. Dr John Cubitt is a registered Chartered
Geologist (CGeol) and has a BSc and PhD in geology. He has compiled, read and
approved the technical disclosure in this regulatory announcement relating to
the Company's interests in Colombia.



The Company also clarifies that the placing completed by the Company earlier
this month, in which Rickerbys participated, was done at a placing price of 1p
per ordinary share and not the nominal value. As previously announced Rickerby's
increased their interest in the Company from 2.75 per cent. to 6.06 per cent..
