Colibri Resource Corp. Drilling Expands Near-Surface Silver-Lead-Zinc Mineralization at Ramard Project, Sonora, Mexico.

 Vancouver, January 25/CNW/Colibri Resource Corporation has received assays from percussion drilling of the first 10 holes in a minimum 50 hole program 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 between the Mexican subsidiary of Colibri, Minera Halcones SA de CV, and a private Mexican company. Exploration focus is on approximately 4 square km of skarn, hornfels and associated porphyry intrusive rocks, historically known as the “La Bronca” silver mines. All holes were drilled vertically into skarn beds that dip 15 to 20 degrees, thus, drill intervals reported represent near true widths.

Sedimentary stratigraphy is a Paleozoic shelf group that is highly skarned. Drilling has intersected numerous near surface skarn horizons, “mantos” containing silver, lead and zinc detailed below.

  • 253.8 gpt silver (grams per metric tonne, equivalent to 8.28 ounces/metric tonne), 2.3% lead, 8.5% zinc over 6 meters in RPD1, between 1.5m and 7.5m
  • 872.8 gpt silver (28.1 ounces/tonne), 8.7% lead, 8.8% zinc over 1.5 meters in RPD2 between 16.5m and 18m
  • 131 gpt silver (4.2 ounces/metric tonne) 1.8 % lead, 7.0% zinc over 1.5 meters in RPD7 between 0 and 1.5m.

There are at least two distinct parallel or nearly parallel mineralized horizons; hole RPD2 cut 28 ounces per tonne silver, 8.8% zinc between 16.5-18m depth, plus 2.3 ounces per tonne silver, 5.19% zinc between 24-25.5m, (end of hole).
Disseminated silver-lead-zinc also occurs within interbedded hornfels and skarn. In hole RPD1, between 7.5m and 22.5m, averages 10.9 gpt silver (range 2.7-39.7 gpt), 0.14% lead (range of 363ppm — 0.4%) and 0.5% zinc (range of 0.18%-1.2 %), Hole RPD4, between 9 and 25.5m averages 16 gpt silver (range of 2.1-93.1 gpt), 0.25% lead (175ppm — 1.35%), and 0.1 % zinc (range of 193ppm- 0.48%).

These percussion drill holes expand and confirm previously reported results from core drilling (see News Release of June 12, 2006). Mineralization has been confirmed with strike length of more than 145m, with a width of 67m and a possible vertical interval of 31.5m. Surface mapping identified similar skarn/hornfels over approximately 1 km strike length, 300m width and 50m vertical extent with anomalous rock and soil sample

Percussion drilling employs a hydraulic 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 analyzed by International Plasma Labs in Vancouver. Half of the sample is stored for archival purposes.

Mr. M. A. Herdrick, B.Sc., M.Sc., Registered Professional Geologist 1801 in the State of Washington, is the Qualified Person on this project under National Instrument 43-101.
