Message: Callinan Mines Limited - Drilling at Gossan Hill Intersects 5.94 g/Mt over 14.77

Mar. 3, 2011 (PR Newswire) --


VANCOUVER, March 3 /PRNewswire/ - Callinan Mines (TSXV: CAA) (OTCBB: CCNMF) is pleased to report that assay results have confirmed that DDH GOS 28 has intersected 5.94 grams of gold per tonne and 22.00 grams of silver per tonne over 14.77 meters at its Gossan Hill Property, Manitoba. Highlights from GOS 28 are included in the table below.

* true widths represent approximately 60% of core widths.

To date, 27 of 28 holes drilled by Callinan at Gossan Hill have produced gold mineralization (DDH GOS 27 was abandoned at 52 meters due to deviation). The mineralized intersection in hole GOS 28 occurs approximately 100 meters down strike and dip of previously announced GOS 25, which graded 9.73 grams of gold per tonne and 6.91 grams of silver per tonne over a core width of 5.75 meters.

The gold and silver mineralization at Gossan Hill is strongly associated with sulphide mineralization (pyrite, chalcopyrite and galena) within quartz carbonate veining adjacent to a sheared intrusive / volcanic contact zone. Interpretations of mapped geology indicate that the structure has a strike length of at least two kilometers.

Callinan Mines maintained a QA/QC program at all stages of exploration. Drill core recovery was calculated, measured and recorded at the Gossan Hill Property before being cut and sampled. Samples were split in half, one half of each sample being kept for storage and the other half placed in a pre-labeled plastic bag, tagged with the sample number and recorded in the log. Callinan QA/QC samples were inserted into the group of samples and shipped to Acme Analytical Laboratories in Vancouver, BC, where they were crushed, split, and pulverized to 250 g samples at 200 mesh. Pulp samples were then assayed by Aqua Regia digestion ICP-ES analysis (24 elements) and assayed for gold and silver by fire assay method. The lab employs internal quality control by assaying pulp duplicates and inserting quality control standards of predetermined values and a blank sample.
