The controls on the mineralisation are poorly understood due to the intrusion of multiple post-mineralising, dolerite dykes which have disrupted the host mafic/ultramafic stratigraphy and further drilling will be planned after a comprehensive review of the data. A review of airborne and ground EM data defined a subtle anomaly ~4.1km south south-east of Zest coincident with the south-east margin of the large gravity anomaly referred to above. The anomalous copper results intersected in drilling are associated with chalcopyrite and confirm the metal fertility of the underlying geology.

The drill results also indicate that previous geochemical sampling would have been ineffective due to the thickness of transported cover in the local area. Infill geophysical programs including gravity and IP are being planned to assist with optimising follow up drilling. 126 air-core holes have been drilled across a number of previously untested coincident geochemical/geophysical targets located on both the Moora and Koojan JV Projects.

The completed holes are part of a larger 160-180 hole program; however, due to early, unseasonal wet weather and the commencement of cropping activities, the remainder of the planned program will now be completed later in the year after harvesting. A 6,000-sample geochemical program designed to infill previously identified, partially defined anomalies and assess new areas is ongoing, with ~65% of the samples collected and submitted for assay. Despite the limited effectiveness of geochemical sampling, it is still considered to be a cost-effective exploration technique with the results needing to be combined with other datasets to define drill targets.

Initial assays for the air-core and geochemical samples are expected in May/June 2022. A review of geophysical data collected late 2021/early 2022, including gravity, aeromagnetics and Gradient Array Induced Polarisation (GAIP), is largely complete and is expected to define other targets for follow up by infill geochemistry and/or drilling.
