Cockie Creek a porphyry by any other name

The Cockie Creek prospect is living up to the technical description of a porphyry deposit. Owner Superior Resources announced copper and gold assay results from the seventh drill hole (CCDD007) indicating ‘… the zone of copper-gold mineralisation widens significantly in the western part of the historical mineral resource.' ‘Increasing width of the mineralised zone and its development in the footwall meta-andesites indicates a deepening of the mineralising system,' the company stated. ‘This is consistent with approaching a cupola or “top” of a mineralised porphyry intrusion.’ The latest results were three times the length of the mineralised intervals in other drill holes in the eastern zone but the grade was lower, the report said.

'The down-dip extension ended within mineralisation at 304m. 'Results from CCDD007 increase the potential for the discovery of a large porphyry copper-gold-molybdenum mineralisation system,’ the report said. Porphyry 'discovered' The results of the maiden program at Cockie had been notable considering that only a few years ago a preserved porphyry belt was not known to exist in this part of Australia, Superior managing director Peter Hwang said. Superior Resources managing director Peter Hwang “With only the first seven holes of our maiden drilling program, we have confirmed the existence of a strongly mineralised porphyry system, that rather than being the historically understood 80 to 90m zone of copper mineralisation, is a rapidly expanding zone of porphyry mineralisation, so far identified, to about 450m depth," he said. “Even though the grades to date have been relatively high for peripheral wall rock mineralisation, we are expecting the core or cores of the system to be truly impressive. “The historic IP geophysical survey highlights the mineralisation well and, consistent with the drilling, shows a significant expansion of the mineralised zone at depth and to the west. "However, the survey covers only a very small area of the interpreted 3.5km x 2km Cockie Creek intrusive complex. So, we will be expediting a modern, prospect-wide IP survey to cover the entire complex. “We are very much excited and looking forward to the next exploration programs on both Cockie Creek and Bottletree, each of which, have the potential to result in significant discoveries. “We will also be planning a maiden program on a possible third porphyry, Wyandotte. In the meantime, we aim to provide further information on Cockie Creek from our interpretation of results and also Bottletree as assays are received from the lab.”
