Callinan Mines has received final assays from the drilling conducted this past summer season at their wholly owned Coles Creek property in Northern BC near Smithers.
The program consisted of 7,069 metres of diamond drilling, focused on a mineralized volcanic zone approximately 1.5 square kilometers in area. Analysis of drill logs in context of assay results suggest a system of strata-bound epithermal silver-zinc-lead-gold mineralization hosted in a volcanic sediment package, created by a collapsed caldera exceeding 3 kilometers in circumference. Mineralization within this sedimentary basin has proven to be pervasive over large widths (greater than 200 meters). These results indicate the potential for a large, complex, multi-element mineralized structure. President Mike Muzylowski stated that "Further drilling is warranted to test for higher grade in this extensive caldera."
Callinan Mines maintained a QA/QC program at all stages of exploration. Sample recovery was calculated, measured and observed at a company facility on site at Coles Creek before being cut at the same facility. Samples were sawn in half, one half being kept for storage and the other half placed in pre-labeled plastic bags, tagged with the sample number and recorded in the log. Samples were then shipped to Acme Analytical Laboratories in Vancouver, BC, where they were crushed, split, pulverized and sieved into approximately 30 g samples at 200 mesh. Samples were then assayed by Aqua Regia digestion ICP-MS analysis, and by fire assay fusion method for silver and gold. The lab employs internal quality control by assaying pulp duplicates and inserting quality control standards of predetermined values and a blank sample.
