Colibri intersects additional near surface mineralization at Ramard; 370 grams per tonne silver, 12.2% lead, and 11.9% lead, plus wide intervals of disseminated silver-lead-zinc

VANCOUVER, May 27, 2011 /CNW/ - Colibri Resource Corporation is pleased to report more results of a 2000 meter drilling program at the Ramard silver project, in Sonora, Mexico.

The Ramard property (see www.colibriresource.com) consists of over 4000 hectares of mineral concessions located 100 km north of the city of Hermosillo, Sonora, wholly owned by Colibris Mexican subsidiary, Minera Halcones.  The Ramard property contains numerous historical artisanal silver mine workings.

Assays have been returned from holes 6-10 of 28 drill holes.

All holes were drilled across a gently dipping skarn/manto formation and are believed to be close to true width (within 10%).

Holes BRAPD6, BRAPD7 and BRAPD8 all intersected broad intervals of disseminated silver-lead-zinc mineralization, BRAPD 7 cut 23 meters of 11.1 grams per tonne (gpt) silver, 0.027% lead, 0.63% zinc and was terminated in mineralization due to drilling conditions.  BRAPD8 drilled adjacent to hole 7 cut 5.95 gpt silver, 0.41% zinc between surface and 13 meters depth, and 6.36 gpt silver, 0.11% zinc between 24 and 67 meters.

BRAPD9 was targeted across similar appearing skarn.  The entire hole is mineralized with 13.6 gpt silver, 0.38% lead, 0.85% zinc between surface and 99 meters depth.  There are two high grade intervals; 1) between 2 and 8 meters averaging 97.9 gpt silver, 0.79% lead, 4.88% zinc, including 2 meters of 118 ppb gold, 231.8 gpt silver, 1.4% lead, 4.84% zinc between 3 and 5 meters depth, and 2) between 21 and 27 meters 85.8 gpt silver, 2.53% lead, 4.2% zinc, including one meter of 236 ppb gold, 370.2 gpt silver, 12.24% lead, 11.93% zinc.  Between 1 and 27 meters depth, 26 meters averaged 42.9 gpt silver, 0.78% lead, and 2.26% zinc.

BRAPD10 was targeted 100 meters from hole BRAPD2.  It intersected mineralization along its entire length averaging 13.9gpt silver, 1% lead, 0.92% zinc between surface and 84 meters depth, when the hole was terminated due to difficult drilling conditions.  Higher grade intervals include surface to 20 meters depth 40.7 gpt silver, 0.37% copper, 2.99 % lead, 2.48% zinc, including between 16 and 20 meters depth of 140.8 gpt silver, 1.33% copper, 9.78% lead, 3.64% zinc.

Mineralization in hole BRAPD9 is more than 200 meters distant from BRAPD2 which contains similar high grade concentrations of silver, lead and zinc (see news release of May 18, 2011), an indication of the size and scope of this system.

These results further demonstrate the potential of the Ramard project, with both high grade manto horizons plus disseminated silver, gold, lead, zinc.  Access on the project is excellent, with a paved road less than 1 km from the drill sites and the railhead at the town of Carbo less than 10 kilometers distant.

The company is waiting for analyses of the remainder of the drill holes.

Drilling was conducted using a direct circulation, rotating hammer, track mounted rig and Ingersoll Rand 750 cfm compressor.  Drill hammer width is 4.5 inches.  Samples were collected in a cyclone at one meter intervals and split with a Jones splitter.  All samples were split on site with half of the sample kept for archival purposes.   At least one duplicate sample was collected from all holes.  Samples were taken directly to Inspectorate Laboratory sample preparation lab in Hermosillo, Sonora at the end on each days drilling.  Sample pulps were analyzed by Inspectorate in their laboratory in Richmond, British Columbia using AuAg-1AT-GV for gold and silver and BM-AR-OR for copper, lead and zinc, quantitative procedures designed for ore grade samples.

Exploration was conducted under the supervision of J.J.
