Colibri to commence drilling on Ramard Silver property, Sonora, Mexico


VANCOUVER, Feb. 17 /CNW/ - Colibri Resource Corp. (TSX.V:CBI) is pleased to announce an initial 2000 meter, diamond core drill program on the Ramard property in Sonora, Mexico to commence in March, 2011. The Ramard property consists of over 4000 hectares of mineral concessions located 100 km north of the city of Hermosillo, Sonora, wholly owned by Colibri's Mexican subsidiary, Minera Halcones. The Ramard property contains numerous historical artisanal silver mine workings.

In 2006 and 2007, drilling was completed on the property with a small, portable core-drill rig and a percussion rig, reported in a series of 2007 press releases (see Drill collar locations and representative drill sections are shown at Every drill hole intersected silver-lead-zinc mineralization, with copper present in some holes. Mineralization is open and untested at depths greater than 40 m (the limit of the percussion drill rig).

This drill program intercepted concentrations of up to 1235 grams per metric tonne (gpt) silver (Ag) and greater than 20% combined lead/zinc (Zn/Pb) and 1% copper (Cu) (see summary Table 2) over widths of 1.5 meters, all at less than 40 meters depth from the surface. Nine of the 95 total borings contained a silver intercept greater than 310 gpt (10 troy ounces). Mineralization in the Bronca Zone (81 holes) occurs over at least 1 kilometer length, 300 meters width. All eight drill holes at the Verde Zone cut zinc mineralization within skarned calcareous shale and limestone. RPD83 cut 10.5 metres averaging 7.25% zinc between the surface and 10.5 metres depth.

Planned drilling will target the Bronca Zone with a diamond core rig and the untested contact zone between the skarn and underlying rhyodacite porphyry. Additional targets are presented in the Verde Zone and in other untested targets that cover old mine workings.

These prior drill results from this project are similar to 43-101 compliant mineral resources for silver in the State of Sonora, e.g., the Alamo Dorado mine (controlled by Pan American Silver Corp.), the Santa Elena mine (SilverCrest Mines, Inc.), and the Promontorio Project (Kootenay Gold, Inc.). Like Ramard, these silver projects are developed within old mining districts with numerous artisanal mine workings.

Exploration was conducted under the supervision of J.J. Irwin, B.Sc., Ph.D., the qualified person under National Instrument 43-101 on this project.
