HIGHLIGHTS
- Cockie Creek drill hole CCDD007 has delivered the broadest width of porphyry copper and gold mineralisation to date in the western part of the Cockie Creek Prospect
- Maiden drilling program reveals continuous zone of copper and gold mineralisation extending from surface to a vertical depth of at least 450m in the western zone
- New assay results from CCDD007 and CCDD003 reveal that the zone of Cu-Au 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. This is consistent with approaching a cupola or “top” of a mineralised porphyry intrusion
- CCDD007 includes:
o 320m @ 0.21% Cu, 0.05 g/t Au and 31 ppm Mo from 176m (CCDD007)o incl. 271m @ 0.24% Cu, 0.05 g/t Au and 36 ppm Mo from 225m
o incl. 171m @ 0.32% Cu, 0.07 g/t Au and 40 ppm Mo from 225m
o incl. 69m @ 0.52% Cu, 0.10 g/t Au and 69 ppm Mo from 225m
o incl. 23m @ 0.70% Cu, 0.12 g/t Au and 68 ppm Mo from 265m
o incl. 13m @ 0.89% Cu, 0.13 g/t Au and 79 ppm Mo from 265m - The broad interval of porphyry copper and gold mineralisation in CCDD007 is approximately three times the length of the mineralised intervals in CCDD001, CCDD002, CCDD004 and CCDD006 in the eastern zone, although it has an overall lower average grade
- Results for CCDD007 combined with CCDD003 and historic drill hole CRC014 reveal a continuous zone of copper and gold mineralisation from surface to a vertical depth of approximately 450m in the western zone
- CCDD007 identified the down-dip extension of copper and gold mineralisation in CCDD003 (248m @ 0.28% Cu from 56m), which ended within mineralisation at 304m
- Assays from CCDD007 are consistent with those in CCDD003 and CCDD005 and show that mineralisation in the western zone extends well into the andesitic wall-rocks below the main Cu-Au zone in diorite, quartz diorite and lesser tonalite porphyries
- Sulphide mineral assemblages, alteration styles, mineralisation grades and the presence of porphyry “B veins” and abundant late-stage “D veins” at Cockie Creek are all features typical of porphyry Cu-Au-Mo deposits
- Results from CCDD007 increase the potential for the discovery of a large porphyry Cu-Au-Mo mineralisation system
Superior Resources Limited (ASX:SPQ) (Superior, the Company) announces new copper and gold assay results from the seventh drill hole (CCDD007) of the Company’s maiden program at the Cockie Creek Prospect. Cockie Creek is one of several porphyry copper-gold-molybdenum prospects within a newly recognised porphyry belt at the Company’s 100%-owned Greenvale Project.
The copper and gold assays from CCDD007 in the western zone of Cockie Creek are of relatively high grade in terms of porphyry copper-gold-molybdenum deposits and duplicate the grades encountered in CCDD003 drilled 70m north of CCDD007. Importantly, CCDD007 successfully confirmed the down-dip extension of mineralisation in CCDD003, which terminated within Cu-Au mineralisation at 304m (End-of-Hole). The wide interval of Cu and Au mineralisation in CCDD007 is approximately three times the length of the intervals encountered in the four drill holes in the eastern zone of Cockie Creek, although at lower overall average copper and gold grades.
Notably, the assays from CCDD007 continue to confirm that the actual copper grades have consistently exceeded visual estimations of chalcopyrite mineralisation observed within the core.
Superior’s Managing Director, Peter Hwang commented:
“The results of the maiden program at Cockie have been outstanding and highly notable, especially considering that only a few years ago a preserved porphyry belt was not known to exist in this part of Australia.
“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 90 metre zone of copper mineralisation, is a rapidly expanding zone of porphyry mineralisation, so far identified, to about 450 metres depth.
“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.”
