Porphyry Cu-Au-Mo Mineralization Drilled at Strongbow's Inza Property, British Columbia
| ||Strongbow Exploration Inc. (SBW: TSXV) is pleased to report that Xstrata Copper Canada ("Xstrata") has forwarded results of the 2011 exploration program at the Inza copper-gold exploration property in north-central British Columba. The 6,104 ha property is located within the Quesnel Trough region, approximately 54 km north-northwest of the community of Fort St. James and 40 km southwest of the Mount Milligan copper-gold mine. From July to September 2011 Xstrata completed 1,700 metres of drilling in nine drill holes, 40 km of ground IP geophysical surveys, the collection of over 400 soil geochemical samples, as well as geological mapping and prospecting surveys. Initially, a 1,000 m drilling program was planned, however the overall program was expanded considerably based on initial drilling results. |
Exploration work tested a thirty-five square kilometre area that encompasses two distinct magnetic anomalies. Drilling has confirmed that the northwestern magnetic anomaly is associated with a feldspar-hornblende porphyry that intrudes a mixed sequence of Takla Group intermediate volcanic and fine grained sedimentary rocks. The porphyry is comprised of multi-stage intrusive phases and breccias, and consistently contains disseminated pyrite (up to 3%) with local concentrations of visible chalcopyrite and molybdenite. Volcanic and sedimentary wall-rocks are typically hornfels-altered proximal to the porphyry and contain up to 5% disseminated and veined pyrite. Elevated copper, gold and/or molybdenum values were intersected in six of the nine drill holes with values ranging from detection up to 0.12% Cu, 2.2 g/t Au and 0.10% Mo. The bulk of anomalous copper values (defined as >90th percentile) were returned from drill holes testing the northern magnetic anomaly. In particular, drill hole Inza-11-05 returned a 42.5 m zone of elevated copper values within hornfels altered intermediate volcanic rocks. Importantly, this mineralized zone is located at the northern end of an IP chargeability anomaly that extends for over 2,000 metres and coincides with the northwestern magnetic high anomaly. Xstrata has indicated that planning is underway for additional ground and airborne geophysical surveys in advance of a 2012 drilling program intended to further test the deep potential of this porphyry system.
The 2011 exploration program at Inza was operated and funded by Xstrata as part of an option agreement whereby Xstrata may earn up to a 75% interest in the property (please see Strongbow news release #11-08 dated April 27, 2011 for details).
David Gale, P.Geo. (BC), Strongbow's VP Exploration, and a qualified person under NI 43-101, has reviewed the drill core from the 2011 drilling program and the technical information in this release. All drill samples and analytical data for the Inza project were collected under the supervision of the project operator, Xstrata Copper Canada, using industry standard QA-QC protocols. All samples received both an ICP and fire assay analysis and were tested by SGS Mineral Services in Vancouver, BC. The ICP analysis provided results for 32 elements using a 0.2 gram sample split and a four acid digestion with ICP Optical Emission Spectrometry. For fire assay analysis, samples were crushed and pulverized to produce a pulp and a 30 gram sample split was mixed with flux to produce a dore bead. The bead was digested in acids and the solution analyzed by an Atomic Absorption Spectrometer.
