Colibri continues drilling on Leon Project, soil anomaly expands

    Listed TSX-V: CBI

    VANCOUVER, Feb. 13 /CNW/ - Colibri Resource Corporation is continuing
core and percussion drilling on the Leon Project, Sonora, Mexico. This project
presents multiple drill targets, including mineralization associated with
4 separate clusters of artesanal underground mine workings. The Amarillas,
Tramado and Bellota zones are former producing precious metal mining camps and
the Fortuna zone is an underground molybdenum-copper working. 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.
    Ongoing soil sampling has expanded the area of anomalous soils between
the Amarillas Zone mine workings and the Variedad copper-molybdenum prospect.
Samples were collected at 50m intervals on North-South directed lines 100m
apart. Within an area of approximately 1 square kilometer out of a total of
216 soil samples, 138 contain greater than 500 ppm zinc, 43 contain greater
than 1,000 ppm zinc (9 greater than 2,000), and 104 greater than 250 ppm
copper, 28 greater than 500 ppm copper. Continuous strings of soils are
anomalous. On line 6300E, 13 samples between 5000N and 5650N all contain
greater than 500 ppm zinc with an average of 1340 ppm zinc and 252 ppm copper.
On line 6400E 15 samples between 5000N and 5750N all contain greater than
500ppm zinc with an average of 1280 ppm zinc and 345 ppm copper. These sample
strings are oriented perpendicular to the dominant east-west regional
structural grain. Molybdenum, gold, lead, arsenic, iron and manganese are also
    This soil chemistry anomaly is broadly coincident with an east-west
trending, elliptical shaped negative magnetic anomaly in airborne survey data
available from the Mexican government. The zone of greater than 250 ppm copper
concentration in soils correlates best with the magnetic low anomaly. The
Variedad Cu-Mo soil anomaly encompasses a strong negative magnetic signal
associated with this trend (see figures on
    Hand samples and drill core samples of unaltered, granodiorite host rock
in the Amarillas Zone typically manifest a positive magnetic signature due to
the primary magnetite common to this type of rock. In contrast, quartz veins
and stockworks are non magnetic due to replacement of magnetite by secondary
sulfide minerals such as pyrite.
    Outcrop is generally poor in the area of this coincident soil-magnetic
anomaly but subcrop and float consists mostly of intensely sericitic-argillic
altered intrusive and quartz.
    11 diamond core drill holes have been completed so far, with assay
results pending for most. Drilling by Landdrill International SA de CV is
ongoing, as is percussion drilling.
    The Leon Project now consists of approximately 5,800 hectares of mineral
