Nuinsco Resources Limited ("Nuinsco" or "the Company") (TSX:NWI) today reported results for six drill holes amounting to 501m, completed upon the CBay Minerals ("CBay") properties in the Chibougamau mining camp area of north-central Quebec as part of a 15- hole, 1,560m autumn program of NQ diameter core drilling. CBay is a private company owned on a 50-50 basis by Nuinsco and Ocean Partners Investments Limited.
Results reported here are from two holes that tested a geophysical anomaly located approximately 40km south of Chibougamau, and four holes completed for the purposes of infill, grade confirmation and mineralization characterization at the Devlin copper deposit situated approximately 18km south of Chibougamau.
Holes NJ-1301 and NJ-1302 tested a discontinuous geophysical anomaly 3km in length which cuts highly deformed volcanic rocks. The area lies along the northern margin of an east-west striking corridor of intense deformation and sits 3km northeast of the significant past-producing Joe Mann gold mine (4.75M tonnes at 8.26 g/t Au, total production 39.27 tonnes of gold). The two holes cut pyrrohtite/pyrite-rich, fissure-hosted mineralization, the cause of the geophysical response. Although analyses of the mineralized intervals revealed no significant precious metals content, two short intervals of highly-anomalous zinc were present in NJ-1301. In light of similar intersections encountered in the immediate area surrounding the property during historic drilling in the mid-1980s and earlier, which investigated deeply-covered airborne geophysical targets, the Company is considering the merits of further work directed towards non-conductive zinc-rich massive sulphides at this time.
The drilling completed at the flat-lying, near-surface Devlin copper deposit was confined to the central part of the mineralized domain which in total consists of five main lenses within a 365m by 210m area encompassing the bulk of the contained copper mineralization demonstrated by prior work. Devlin comprises a sub-horizontal vein-hosted deposit from which an underground bulk sample was obtained, the results of which were reported in 1982. The bulk sample was accessed by means of a 610m ramp and drifts. Vertical drillholes DEV-CB1 through DEV-CB4 were spaced 30m to 60m apart near the central part of the deposit to intersect the shallow northeast-dipping copper mineralization.
The samples taken were tested for specific gravity by weight in air vs. weight in water method, for gold content by traditional fire assay with AA finish, and for a suite of 34 elements (25 gram sample) by ICP-AA geochemical methods for copper content and to reveal the presence of any deleterious elements such as lead and arsenic. Samples returning values greater than 5% copper were re-run with the more rigorous AA-46 ore grade geochemical method by assayer ALS-Chemex for a precise determination of copper grade. Arsenic content in the samples tested was uniformly at or below the 10ppm lower detection limit for the element, with results very similar for lead, excepting those with very high copper content where lead was found present at trace levels ranging from 20ppm-70ppm.
