VANCOUVER, June 19 /CNW/ - Colibri Resource Corporation has received
assay results from percussion drilling of an additional 8 percussion drill
holes (RPD82 - RPD89) on the Ramaje Ardiente (Ramard) Project in Sonora,
Mexico. The Ramard Project is held by an option agreement to acquire 100%
ownership of 8,419 hectares made between the Mexican subsidiary of Colibri,
Minera Halcones SA de CV, and a private Mexican company. Exploration drilling
is focused on various broad areas of skarn and hornfels developed from
Paleozoic sedimentary rocks with proximal associated porphyry intrusive rocks.
This reported stage of drilling was targeted on the "Verde Zone". All holes
except one were drilled vertically into horizons that dip 20 to 45 degrees
thus drill intervals reported may not represent true widths. One hole was
drilled at -60 degrees to cross possible steeper dipping structurally
The Verde Zone drill holes are located between 2 and 2.5 km distant from
prior reported drilling on the La Bronca prospect (see News Releases of
June 12, 2006, January 25, 2007, February 12, 2007, March 12, 2007, May 2,
2007). The area between these two skarn zones is a mix of isolated outcrops of
porphyry intrusive and minor skarn.
All 8 drill holes cut zinc mineralization within skarned calcareous shale
RPD83 cut 10.5 meters averaging 7.25% zinc between the surface and
10.5 meters depth, (range of 3.28%-9.5% zinc) in a hole 30 meters deep
averaging 3.41% zinc between surface and 30 meters depth (range between 0.28%
and 9.5% zinc),
RPD87 cut 12 meters averaging 4.01% zinc between the surface and
12 meters depth within a 30 meter interval that averages 1.78% zinc from
surface to 30 meters depth (range between 0.05% and 7.4% zinc).
Holes RPD82, RPD85, RPD88, and RPD89 all cut disseminated zinc
mineralization from top to bottom, averaging between 0.74% zinc to 1.11% zinc
over lengths between 15 and 21 meters.
These results demonstrate the widespread extent of mineralization on this
project. The Verde Zone skarn is associated with a magnetic anomaly
approximately 200m wide that extends for 500 meters in a NW-SE direction
following a favorable calcareous bed. There are 3 other zones of visually
similar mineralized skarns extending continuously further south within the
Ramard Project that are not drill tested.

Mineralization remains open at depth and in all directions. Verde Zone
mineralization is dominantly smithsonite with zinc bearing limonitic. Silver
is reported as gpt (grams per metric Tonne), lead as ppm (parts per million),
zinc in % (weight percent). Gold is not usually assayed due to low
concentrations anticipated in this geologic setting.

Air track percussion drilling utilizes a surface air driven hammer with
2.25 inch wide bit and associated compressor. Samples are typically 5 kg of
rock chips over 1.5m intervals. Each sample is split on site with a Jones
splitter and half of the sample taken to Sonora Sample Preparation Lab,
Hermosillo, Mexico, and then transported to Vancouver, B.C. by International
Plasma Labs. The remaining half of the bagged sample is stored in Hermosillo
for archival purposes.
