Drill Results March 2011


On March 15, 2011, assay results were received for drill holes BL11-16 to BL11-24 and indicated that nine of these ten holes successfully intersected the gold-mineralized horizon and extended the zone an additional 400 metres along strike to the northwest of the discovery section and 130 metres to depth for a total strike length of 960 metres and a vertical depth of 330 metres. Only Hole BL11-21 failed to intersect the horizon being collared in a diabase dyke intruded within the gold zone. As the dykes in this area trend in the same direction as drilling, the hole was stopped and the drill moved further northwest along trend to avoid the dyke. Holes BL11-24 and BL11-25 were drilled to the northwest of BL11-21, away from the diabase, and successfully intersected the continuation of the gold mineralization.


Holes BL11-16 to BL11-21 and BL11-24 and BL11-25 were drilled on 100 metre-spaced sections, with each section comprising two holes drilled at different angles to test the zone at vertical depths of approximately 150m and 200m, respectively. Holes BL11-22 and BL11-23 were drilled on two sections, 500 metres northwest and 200 metres northwest of the discovery section, and were designed to test the zone at approximately 300 metres vertical depth.

On March 28, results for diamond drill holes BL11-26 to BL11-28, and the remaining results for drill hole BL11-25, were released and noted the successful intersection of gold mineralization underneath and to the southeast of the original discovery holes.

Gold mineralization intersected in the current holes is similar to that previously reported and is comprised of thick sections of disseminated sulphides hosted by predominantly Timiskaming-age sediments with subordinate gold-bearing granitic pegmatite and amphibolites. Significant widths of gold mineralization were returned from all holes, and include: a 108.9 metre interval averaging 1.1g/t Au in Hole BL10-27, a 136.8 metre interval grading 1.2 g/t Au in Hole BL11-28 and a 119 metre section grading 0.7 g/t Au in Hole BL11-26.

Hole BL11-26 was drilled to undercut the mineralization in Holes BL10-2, 3 and 4 (the discovery holes), as well as Holes BL11-09 and 10, Holes BL11-27 and 28 represent the first complete sections drilled to the southeast of the discovery holes. The latter holes were designed to test the zone at 150 and 200 metres depth.

In addition to gold assays, partial geochemical results have been received for silver with intervals of up to 51 metres averaging 10 g/t in Hole BL11-24 and 194 metres of 5 g/t Ag in Hole BL11-16 identified. The silver zones correlate well with the gold horizon but also occur in the low-grade gold intervals. The identification of potential recoverable quantities of silver requires further evaluation and Management is now considering more robust analytical techniques for the accurate determination of silver concentrations in all drill holes. Currently silver is only analyzed with a geochemical technique, which are indicative of silver concentrations, but cannot be relied upon to determine actual concentrations.
