Colibri initiates reverse circulation drilling program at the Colibri claim site

    Listed TSX-V: CBI

    VANCOUVER, Feb. 19 /CNW/ - Colibri Resource Corporation (Colibri) is
pleased to announce the start of a 2000 meter minimum drilling program at our
Colibri claim northwest of Caborca in Sonora, Mexico. The Colibri claim is
held by an option agreement to acquire 100% ownership of 6564 hectares made
between the Mexican subsidiary of Colibri, Minera Halcones SA de CV, and a
private Mexican company. Exploratory drilling is mostly focused on down-dip
and along-strike projections of historical underground mine workings and
targets identified by an Induced Polarization geophysical survey. Previous
drilling of these targets during 1994, 1998, 2005 and 2007 yielded significant
gold mineralization (see prior news releases posted on Layne Drilling of Hermosillo has been contracted
to provide the reverse circulation drill rig and crew.
    Three areas were targeted for diamond drilling during the 2006-07 season:
the San Francisco mine, the Naranja Zone and the Nopal Zone. Drilling
conditions proved to be exceptionally difficult and water intensive, with
broad intervals of strongly sheared, fractured rock encountered. Core recovery
was generally good, 90-100%. Hematite-flooded breccia or gouge zones with
quartz veins and stockworks are common features of recovered core in all
holes. Several holes were terminated before target depths due to difficult
drilling conditions in strongly sheared, brecciated rock (CDH-1, 6, 7).
Colibri expects the RC drill rig to provide better penetration of the deep
shear zones, with good recovery. The RC drilling method has proved successful
in exploration of other gold deposits in Sonora that are hosted by similar
pervasively faulted rocks (e.g. La Herradura, El Chanate, and La Choya).
    Colibri continues to drill at our Leon claim with a diamond core rig and
has completed 13 holes to date. Results of the first two holes have been
reported (January 21, 2008 news release) and we are awaiting assay results for
subsequent holes. Drilling has progressed from the Las Amarillas polymetallic
zone westward towards the Variedad copper-molybdenum anomaly (see maps posted
on for details). Colibri will continue diamond
drilling at Leon concurrent with the RC drill program at the Colibri claim.
    Exploration is conducted under the supervision of J.J. Irwin, B.Sc.,
Ph.D., the qualified person under National Instrument 43-101 on this project.
