Project Details

Callawa Copper Project, WA

The Callawa Copper Project, located in Western Australia, represents an outstanding opportunity with rock-chips with up to 28.7% Cu at surface supported by other surface rock-chip results of 9.4% Cu, 7.63% Cu and 2.68% Cu. A series of small shallow pits are spread over about 40m related to quartz veins hosted in amph-plag schist. An historic rock-chip result of 19.0% Cu at surface has also been collected.

With samples grading up to 9.4% Cu with 25.9 g/t Ag and 7.63% Cu with 15.7 g/t Ag, there is a strong geological thesis underpinning the presence of a high-grade epithermal copper system that may be feeding off a deeper porphyry intrusive.

The Callawa Copper Project has a prospective strike of approximately 2km. The Callawa Copper Project demonstrates significant potential for a further copper-gold discovery within the Archean Warrawagine Granitoid Complex on the margin of the Pilbara Craton.

During the Quarter ended 31 December 2021, the Company received the assay results from the Phase I exploration program that had been completed during the Quarter ended 30 September 2021, comprising of project wide mapping as well as detailed sampling across the old workings and known zones of outcropping mineralisation.

Several rock chip samples were collected during the mapping program conducted on Callawa as well as a subsequent reconnaissance field visit. The samples were collected in situ and in areas of good rock outcrop as well as around an area known as the Du Valles workings.

The samples collected around the Du Valles copper workings returned high-grade copper including results such as 6.78% Cu, 4.35% Cu, 2.02% Cu and 1.85% Cu. These results demonstrate the fertility of the geological environment and highlight the significant exploration upside that exists at the project.

The samples were collected along an exposed structure/shear zone which is characterised by malachite staining associated with quartz veining.

The samples collected returned very encouraging copper values over an initial strike length of 125m with a high-grade zone over an initial strike length of approximately 40m. Importantly, the strike length remains open and will be expanded upon through continued exploration at the Callawa project. The samples with elevated copper results also show elevated gold, silver and arsenic.

This combination of copper, gold and trace element results are encouraging and may be used as a vectoring tool. The copper grade was also highest at the edges of the sample lines, maintaining the potential for increasing the already identified 125m mineralised strike further by way of future exploration.

The images below depict samples that were collected in the field at the Callawa Project. The malachite is clearly visible in the in-situ rock samples, denoted by the green staining on the faces of the rocks.
