                           Jolly Ranch Project Update


The directors of Nighthawk Energy plc ("Nighthawk" or "the Company") (AIM:
HAWK), are pleased to announce an update in respect of the Jolly Ranch project
located in Lincoln County, Colorado.  The Company holds a 50 per cent. working
interest in the project.  Running Foxes Petroleum Inc., a privately owned
Denver-based energy company, is the operator and holds a 50 per cent. working
interest.

The Jolly Ranch project area covers 40,152 acres and is located within the
prolific Denver Basin, from which production is drawn from Carboniferous
Pennsylvanian, Permian and Cretaceous reservoirs throughout much of the
mid-Continent region of the US.  The primary targets are the Marmaton and
Cherokee carbonates and secondary objectives are Morrow, Atoka and Cretaceous
sandstones.

The project acreage contains two oilfields, Bolero and Craig Ranch, which were
abandoned during the late 1980s and early 1990s due to completion practices at
that time and low oil prices.

An independent study has been conducted by Bowler Petrophysics Inc., a
Denver-based petrophysical company, with the objective of identifying oil
producing reservoirs in the carbonates and sands and source rocks from three
previous production wells located within the project area, Craig 1, Craig 4-34
and Craig 8-1X.  These wells were drilled in 1984, 1985 and 1995 by Mull
Drilling Company, BHP Petroleum and Anschultz respectively.

Digitised log interpretations using JLog and MacLog software for these three
wells have been evaluated for hydrocarbons in place on a 40 acre spacing.
Results showing formation, depth intervals, estimated hydrocarbons in place and
total net pay thickness are set out below.


Well              Formation        Depth Interval        Hydrocarbons in place    Net Pay
                                      (feet)              (barrels of oil)        (feet)

Craig 1           Marmaton         6,422 - 6,427                206,000             5.0

Craig 1           Cherokee         6,608 - 6,609.5               43,850             1.5

Craig 4-34        Marmaton         6,435 - 6,442.5              253,000             7.5

Craig 8-1X        Marmaton         6,182 - 6,191.5              362,000             9.5



The Marmaton and Cherokee pay zones, based on the present data set, cover the
entire acreage held.  In addition, the report identifies additional bypassed oil
zones in the wells that are recommended to be tested.  These zones will be
further exploration targets in future wells within the project area.

A development programme will commence at Jolly Ranch with the re-drilling of
Craig 1 in September 2007, followed by the re-drilling of Craig 4-34 and Craig
8-1X in the fourth quarter of 2007.  In addition, a 3-D seismic programme of 21
square miles will commence over the project area in September 2007.

David Bramhill, Managing Director of Nighthawk commented "Since we acquired
Jolly Ranch in June, our expectations in respect of the project have increased
and this has been confirmed by the evaluation work carried out by Bowler
Petrophysics.  We believe that Jolly Ranch has the potential to add significant
value to Nighthawk."

David Racher B.Sc (Hons) Geology, who is a consultant to Nighthawk, has reviewed
and approved the technical information contained in this announcement.
