Cardinals

The Cardinals zinc gossan is located approximately 130 kilometres south-south-east of Port Hedland in Western Australia, and covers potential strike extensions to the host rocks of CBH Resources Ltd's Panorama-Sulphur Springs base metals project, which is slated for commencement of construction of an open pit development in 2007.  Zinc Co can earn up to 75% interest in the Cardinals project, with Giralia retaining nickel exploration rights.

Location and Geology of the Cardinals Project

Location and Geology of the Cardinals Project
The regional geology of the area is dominated by a north-east trending, steeply dipping, folded sequence of Archaean basic and felsic rocks, and sediments of the Sulphur Springs Group which form part of the belt surrounding the Strelley Dome.  The cherts and felsic volcanic rocks within this belt are correlated with the Kangaroo Caves Formation and host the Cardinals gossan and several similar gossans, including Sulphur Springs.

Geology of the Cardinals Project

At the Cardinals prospect ferruginous gossans with malachite and azurite occur as lenses in unaltered agglomerate rhyolite tuff and basic schists adjacent to a narrow chert horizon. The prospective acid volcanic units vary in thickness up to 200 metres near Cardinals gossan, where coarse agglomerate probably indicates proximity to a volcanic centre.  To the south the prospective horizon is masked by Tertiary gravel outwash, while to the north the upper part of the acid tuff horizon is dissected by a serpentinised pyroxenite intrusion.

Better results from six percussion holes and three subsequent angled diamond drill holes completed between 1976 and 1982 are tabulated below:

Section showing Zinc Mineralisation and Geological Interpretation of the Cardinals Project

Rock samples up to 22% Zn, 7.0% Cu, 8.0% Pb, 115 g/t Au and 0.96 g/t Au; 10.7% Zn, 10.4% Cu; and 9.1% Zn, 3.2% Cu and 2.4% Pb are reported from the Cardinals gossan.  Another gossan outcrop, the Aloha gossan, in the south-eastern part of the tenement returned up to 16% Zn and 32% Cu from rock sampling.

Reinterpretation of the previous drilling shows that the massive sulphides at Cardinals are probably located in the east limb and keel of a shallowly south-plunging synform.  Judging by the extent of rodding lineations in surface outcrops, the massive sulphide body is likely to be an elongate cigar-shaped plunging shoot.  The single hole tests on sections 11000N (XD 67) and 11100N (XD 66) are unlikely to have satisfactorily tested a body of this shape. Reinterpretation of 1979  SIROTEM geophysical data highlights strong EM anomalies extending south from the Cardinals gossan  with depth to top of the source estimated at no greater than 40 metres suggesting that the 3 holes drilled by in 1981 were probably targeted too deep to test the observed conductors. Mapped shallow plunging lineations suggest that the conductive body, which is less than 40 metres below surface could represent a south plunging, cigar-shaped massive sulphide pod.

Further drilling is planned at the Cardinals gossan, particularly to the south and immediately beneath hole XM 4, and along the EM conductor axis.  The Aloha gossan also warrants assessment in detail.
