/C O R R E C T I O N from Source -- Colibri Resource Corp./



    
    A correction from source is issued with respect to the release issued
    Monday at 9:35 am ET. In the headline, rhenium concentrations of up to
    2,530 ppb were intersected, not 2,830 ppb. This is also corrected in the
    accompanying text and table. Also, drill holes LEPD 84 and LEPD85 dip at
    -60 degrees, not the -45 degrees shown in the table.

    The correct release follows:

    Colibri percussion drilling confirms and expands high grade molybdenum on
    Leon Project, core check assays show rhenium concentrations up to
    2,530 ppb intersected over 2.0 m.

    VANCOUVER, Aug. 25 /CNW/ - Colibri Resource Corporation is pleased to
report results of new percussion drilling and analyses of rhenium from core
samples previously reported on the Leon Project, Sonora, Mexico.

    
    Azul Zone Drill Highlights:
    ---------------------------
    
    Core results for the Azul Zone were previously reported (June 11, 2008)
for LEDH18 (72 meters of 0.195 % Mo between 22 and 94 m) and LEDH17 (72 meters
of 0.120 % Mo between 0 and 72m). Ten percussion drill holes have extended
known mineralization to greater than 250 meters in strike length and a minimum
width of 120 meters. Mineralization is open along strike to the east and west
and down dip to a known depth of at least 130 m. Multiple stages of
mineralization are observed in drill core including high grade Mo-bearing
quartz veins and stockwork. Correlations between high grade intervals in core
and percussion drilling suggest a near east-west trend and dominantly steeply
north-dipping orientation.
    Percussion drill holes LEPD84 and LEPD85 were collared 40 meters to the
west of core holes LEDH17 and 18. LEPD85 intersected 15m of 0.183% Mo between
15 and 30m, including 3m of 0.56% Mo between 15 and 18 meters depth. This hole
ended at 30m depth in 0.280% Mo, 0.228% Cu. LEPD84 intersected 0.03% Mo over
18m between 7.5 and 25.5m, ending in 0.037% Mo.
    Percussion holes LEPD87 and LEPD88 were collared 54 meters east of core
holes LEDH17 and 18. LEPD87, directed due north at -45 degrees, averaged 0.12%
Mo over its entire 39 meter length, including 3 meters of 0.66% Mo between
16.5 and 19.5 meters depth, ending in 0.033% Mo. LEPD88, directed at azimuth
135 degrees at -45 degrees, averaged 0.203% Mo between 0 and 33 meters depth
including 4.5 meters of 0.659% Mo between 22.0 and 27.0 meters.
    LEPD89, collared 102 meters east of core holes LEDH17 and 18, intersected
disseminated Mo averaging 0.065% over the entire 42 meter length of hole,
including 0.091% Mo between 15 and 42 meters. LEPD90, collared 142m east of
LEDH17 and 18, averaged 0.051% Mo between surface and 22.5m, including 3m of
0.191% Mo between 13.5 and 16.5 meters. LEPD 91, collared 126 meters southeast
of LEDH17 and 18, cut 25.5 m of 0.078% Mo between 16.5 and 42m, ending in
0.085% Mo and including 1.5m of 0.24% Mo, 0.093% Cu between 24 and 25.5m.

    
    Fortuna Zone Drill Highlights:
    ------------------------------
    
    The Fortuna Zone, a historic underground mine working along a moderately
south-dipping structure, was previously tested by core hole LEDH19. Nine
percussion drill holes on the footwall of the Fortuna Zone expanded the known
extent of mineralization 150 meters to the northeast. LEPD77 cut 1.5 meters of
0.242% Mo between 1.5 and 3.0 m depth. LEPD81 cut 7.5 meters of 0.133% Mo
between 6 and 13.5 meters, and LEPD83 averaged 0.022% Mo over 30 meters, the
entire length of the hole. LEPD78 ended in 1.5 m of 0.177% Mo between 28.5 and
30.0 meters.

    
    Rhenium Analyses:
    -----------------
    
    Rhenium check analyses of core from LEDH-16, LEDH-17 and LEDH-18 were
performed by Activation Laboratories Ltd. Ancaster Ontario utilizing a 56
element ICP-MS scan with a detection limit of 1 ppb Re.
    Selected 2.0 m intervals of high grade Mo-bearing quartz veins and
stockwork from Azul Zone core holes LEDH16, LEDH-17 and LEDH-18 were submitted
for rhenium analysis. 21 of these samples returned assays greater than 200 ppb
Re, with 4 samples greater than 800 ppb Re along core lengths of 2.0 m. Core
hole LEDH18 yielded the two highest rhenium intervals: 2,530 ppb Re (2.53 ppm)
between 26.0 and 28.0m, and 1,500 ppb Re (1.5 ppm) from 38.0 to 40.0m depth.

    
    Exploration Notes:
    ------------------
    
    All 19 percussion holes ended in anomalous Mo, greater than 35 ppm,
LEPD85 ending in 0.280% Mo, LEPD78 in 0.177% Mo.
    Less than half of the gridded surface area with soil samples containing
greater than 500 ppm copper and 50 ppm molybdenum, (and ancillary anomalous
gold and silver), has been targeted by drilling. Much of the remainder of the
project area remains unmapped and unsampled, and further work is in progress.
    The lithologies and style of mineralization cut by drill core resemble
those of the Creston molybdenum deposit located 3.5 kilometers to the
northeast of hole LEDH19 (see www.crestonmoly.com). The Leon Project is
believed to contain part of the same porphyry system, displaced along a
network of low-angle normal faults (see www.colibriresource.com). The Leon
Project is held by an option agreement between the Mexican subsidiary of
Colibri, Minera Halcones SA de CV and a private Mexican company to acquire
100% ownership of 5,800 hectares of mineral concessions. The Project is
located near the center of the State of Sonora, Mexico, at an altitude of
approximately 1000 meters above sea level, accessed by gravel roads in an area
of moderate topographic relief and logistics favorable for mine exploration
and development.
    NQ-sized diamond drill core samples were provided by Landdrill
International SA de CV. Core samples were cut in half with one portion
submitted for assay and the remainder retained as reference.
    Percussion drilling was conducted from a track mounted vehicle using a
surface air driven hammer with a 2.25 inch wide bit and associated compressor.
Samples are typically 5 kg of rock chips over 1.5 m intervals. Samples were
split on site and delivered to Sonora Sample Preparation Lab in Hermosillo,
Sonora, and analyzed using standard ICP by International Plasma Labs in
Vancouver, British Columbia.
    Exploration was conducted under the supervision of J.J. Irwin, B.Sc.,
Ph.D., the qualified person under National Instrument 43-101 on this project.
