In November, Colibri contracted SJ Geophysics to conduct an Induced Polarization survey for the property. This IP survey covers approximately 2000 hectares of the claim site; fieldwork will be completed by December 22. The survey will cover the LaBronca zone, location of the last drill program and areas to the southwest referred to as “Verde” and “Picacho” Zones. During the IP survey, Colibri geologists will also be completing geological mapping in areas covered by soil and rock grid. The induced polarization survey is being used to locate areas of anomalous- chargeability and resistivity, which are geophysical characteristics often associated with mineralization. Targets developed by the geophysical survey will be correlated with surface soil and rock chip samples, and geological mapping to verify previously identified drill locations and new drill targets. A 2000 meter diamond drill program will commence immediately upon completion of the I.P. survey and geologic mapping. This is scheduled to begin in January, 2012.

Prior results from drilling programs in 2006, 2007 and Spring 2011 are reported in a series of news releases (see www.colibriresource.com/s/newsreleases.asp.). Drill collar locations, summary of assay results and representative drill sections are shown atwww.colibriresource.com/s/Ramard.asp. 

Prior drilling intercepted concentrations of up to1235 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 meter, all at less than 40 meters depth from the surface. Mineralization in the Bronca Zone occurs over at least 1 kilometer length, 300 meters width. 

The drill program will initially focus on expanding the La Bronca Zone. Soil grid and rock chip sampling has commenced at other locations on the project not previously explored by the company. 

The prior drill results from this project are comparable with 43-101 compliant mineral resources for some operating silver mines and advanced exploration projects 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.). All of these silver projects are developed within old mining districts with numerous artisanal mine workings.

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

Holes BRAPD18, BRAPD19, BRAPD20, BRAPD21 all intersected intervals of low grade disseminated silver-lead-zinc mineralization, (see attached table) within broad intervals of abundant, dense, visible sulphide, as yet unidentified. BRAPD22 cut 4 meters of 52.7 parts per billion (ppb) gold, 57.1 grams per tonne (gpt) silver, 0.67% lead, 3.04% zinc between 44 and 48 meters depth. BRAPD23 cut two significant intervals, between 1 and 3 meters below surface, 21 ppb gold, 86.1 gpt silver, 0.055% copper, 3.1% lead, 1.5% zinc, and 105ppb gold, 311.3 gpt silver, 2.01% lead, 3.41% zinc between 37 and 38 meters depth. BRAPD27 cut 10 meters of 38.5ppb gold, 49.6 gpt silver, 0.06% copper, 0.55% lead, 4.87% zinc between 2 and 12 meters depth including 2 meters of 86.5 ppb gold, 182 gpt silver, 0.195% copper, 2.0 % lead, 10.44% zinc between 3 and 5 meters.

The company is in the process of compiling and integrating all results from the 2007 and 2011 drill programs to develop a three-dimensional structural interpretation that incorporates multiple high-grade rock chip samples collected away from the drilled areas.

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.

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.

Hole BRAPD1 was drilled vertically across an outcropping skarn/manto horizon that dips less than 20 degrees and is believed to be true width or close to true width (within 10%). It intersected 1m of 869.2 grams per tonne (gpt) silver, (28 troy ounces per metric tonne), 8.6% lead, 9.4% zinc, 557 parts per billion gold (0.557 gpt) between 6 and 7 meters below surface, within a 7 meter interval, it intersected 228.6 gpt silver (7.37 oz/tonne), 0.066% copper, 2.89% lead, 5.16% zinc, 266 ppb gold, (0.266 gpt).

BRAPD2 was targeted across the same structure as BRAPD1, 113 meters to the northwest along strike, also vertical. It cut 1128.2 gpt (36.4 oz/tonne), 567 ppb gold (0.567 gpt gold), 6.64% lead, 18.13% zinc between 17 and 18 meters below the surface, within an interval of 3 meters that averaged 741.7 gpt silver (23.93 oz/tonne), 5.79% lead, 10.52% zinc between 16 and 19 meters depth. BRAPD2 was terminated at 24 meters depth due to drilling conditions.

BRAPD3 was collared 87 meters from hole BRAPD1 and 26 meters from BRAPD2 (between holes 1 and 2), also vertical and targeted across the same structure. It cut 399.6 gpt silver, (12.9 oz/tonne), 2.62% lead, 19.89% zinc, 420 ppb gold (0.42 gpt), between 22 and 23 meters below surface within an interval of 5 meters that averages 112 ppb gold, 128.2 gpt silver, 0.97% lead, 5.65% zinc between 20 and 25 meters. These high grade intercepts in holes BRAPD1, 2 and 3 are thought to be on the same gently dipping manto horizon and represent close to true widths (within 10%), but this remains to be confirmed by further drilling. BRAPD3 also cut 100.2 gpt silver (3.23 oz/tonne), 4.81% lead, 1.67% zinc between 97 and 99 meters depth, and a completely different mineralized structure.

BRAPD4 was collared 15 meters south of BRAPD1, targeted at -60 degrees and cut 2m of 92 gpt silver between 21 and 23 meters depth, probably on the same horizon.

BRAPD5 was targeted 126 meters southeast from BRAPD1 (239 meters from BRAPD2) within the same skarn/manto system, also drilled vertically. It intersected lower grade disseminated mineralization between surface and 8 meters depth, 14.24 gpt silver, 0.14% lead, 2.34% zinc, plus at 80-81 meters depth, 488 gpt silver (15.74 oz/tonne), 1.75 % lead, 2.86% zinc, 244 ppb gold (0.244 gpt), within a 3 meter interval that averages 212.2 gpt silver (6.84 oz/tonne), 0.78% lead, 2.4% zinc, 102 ppb gold (0.1 gpt). This is a completely separate manto structure from the near surface intervals reported in holes 1-3 and may correlate with the interval between 97 and 98 meters in BRAPD3.

BRAPD Drill Borings-April 2011

In addition to these high grade manto horizons there are broad intervals of low grade disseminated gold-silver-lead-zinc, for example in hole BRAPD1 between 84 and 99 meters averaging 22.8 ppb gold, 8.54 gpt silver, 0.05% lead, 0.3% silver. Every 1 meter sample (100 meters depth) in this hole returned anomalous concentrations of gold greater than 7 ppb, silver greater than 0.5 gpt, and zinc greater than 0.03 percent. The entire hole averages 33.9 ppb gold, 20.5 gpt silver, (uncut, 16.8 gpt if silver is cut to a maximum of 500 gpt), 0.27% lead, 0.54% zinc, between 1 and 100 meters depth, 99 meter interval.

These results illustrate the potential of the Ramard project, with both high grade manto horizons and widely distributed 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.

The drill program will focus primarily on the La Bronca Zone in areas previously identified containing significant levels of silver, zinc, and lead mineralization. A direct rotary, percussion hammer rig producing a 4.5 inch diameter bore hole is being utilized at the site rather than the previously announced diamond core. Drill samples are transported daily to Inspectorate Exploration and Mining Service’s prep lab in Hermosillo prior to being assayed at their lab in Vancouver, British Columbia.

Ramard Silver Project

Previous drill programs at the La Bronca and Verde Zones 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 http://www.colibriresource.com/s/Ramard.asp) 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.
