Four large diameter diamond holes (CODD0132 to CODD0135) for metallurgical test work were drilled for 663.3 metres. The holes were designed to target oxide, transition and sulphide copper mineralisation. Logging and cutting of the core from these holes have been completed and core cutting will be completed shortly. Samples are expected to be submitted to the laboratory in early November and assay results are expected in late November to early December. The metallurgical test work will be conducted in Perth with results expected in the first quarter of 2022. The results from the current drill program will assist with the creation of a geological model for the CZ area. The existing resource model is limited by the absence of a robust geology model, underlined by the lack of geological logging of the previous drill holes. A total of 61 drill holes within the CZ resource area have not been geologically logged, and only 35% of the previous drill metres were sampled. Helix will commence a program of systematically logging these holes to fill the data gaps and build an evidence-based geology model to underpin the next resource model. A key observation from the current geological logging at CZ, is the extensive fault network, and the geometry and kinematics of the faults are poorly constrained. It is probable that these faults will influence the geometry of both the primary and the secondary, `oxide' copper mineralisation. The building of the geology model is a significant but essential undertaking to better constrain the resource estimates and to optimise regional targeting work. This geological logging and sampling work will continue over the coming months.
