For immediate release                                          14 January 2008


                            Black Rock Oil & Gas Plc

                         Acacia Este 2 drilling update


On 28 December 2007 Black Rock Oil & Gas Plc ("Black Rock" or the "Company"),
stock code: BLR, the AIM-traded oil and gas exploration and production company,
announced that the Acacia Este 2 appraisal well in the Las Quinchas Association
Contract in Colombia had been spudded by its joint venture operator, Kappa
Resources Colombia Limited ("Kappa") on 21 December 2007 and that drilling
operations were underway.


Acacia Este 2 was drilled 500 metres north of Acacia Este 1 to a total depth of
3752 feet. Oil shows were encountered over more than one hundred feet whist
drilling the target Tertiary-aged Lower Mugrosa Formation. The well reached
basement at 3720 feet.


Preliminary interpretation of the logs run at total depth indicates the
potential for oil in a number of zones. There are differences in the nature and
thickness of the reservoir sands in Acacia Este 2 compared to Acacia Este 1 that
make correlation between the wells more complex without further seismic data.
These differences are not unusual with reservoir sand deposits formed in a
fluvial environment and the significance of the differences between the well log
responses will be assessed in the light of the test results. The apparent
absence in Acacia Este 2 of the higher performing sands recorded in Acacia Este
1 may impact the flow rates recorded in the Acacia Este 2 test programme.


Preparation for testing multiple zones in Acacia Este 2 has now commenced in
order to assess the well's potential productivity. Results of the testing should
be known within the next 20 days.


Dr John Cubitt, Managing Director of Black Rock Oil & Gas Plc, commented:


"The results of the drilling of the first Acacia Este appraisal well suggest
that we have encountered heavy oil in a number of zones but we recognise that it
is not straightforward to relate the well logs of Acacia Este 2 to those of the
discovery well. Black Rock therefore considers Acacia Este to be a more
complicated field than first anticipated last year which supports our earlier
decision to undertake the acquisition of additional seismic data before the next
appraisal well."
