Callinan Mines Limited (TSX.V – CAA) has mobilized a diamond drill to the Snow Lake area of Manitoba for the immediate commencement of comprehensive drill testing of the Berry Creek, Jean Lake and Watts River claims.

The initial hole of the 2009 – 2010 winter season will be drilled at Berry Creek to test the down-dip extension of mineralized host rock intersected in diamond drill hole BR-4. This drill hole, part of the previous winter program, contained anomalous copper, zinc, molybdenum and rhenium values over a 124.97 meter core length of altered quartz serecite schist and altered ryholite. This alteration is similar to the host rock of the mines in the Snow Lake area. The initial drill hole will be drilled to a depth of 550 meters and is designed to test under the 172.87 meter hole BR4. In addition, diamond drill holes are planned to test the downward extension of a mineralized gold zone intersected in diamond drill hole BR-1. This zone, bearing 1.26 g/mt gold across 6.49 meters of core length, including 15.40 g/mt gold across 0.47m, was intersected between 29.60 meters and 36.12 meters. The planned holes will test the depth of the mineralization.

On the Jean Lake property, gold values as high as 11.44 g/mt have been sampled on surface by Callinan field crews. Gold values in surface samples occur in quartz veining and are associated with arsenopyrite mineralization. Geophysical tests of induced polarization and chargeability, conducted by Callinan, have located anomalies coincident with the sampled areas of mineralization. Three diamond drill holes are planned to test geophysical anomalies coincident with mineralization on the Jean Lake property.
