Rincon Resources Limited announced preliminary observations from a high-level review of the airborne electro-magnetic survey flown in 2022, and the imminent commencement of field activities at its 100% owned Kiwirrkurra IOCG Project, located in the West Arunta Region of Western Australia. Airborne Electro-Magnetic Survey (AEM) In October 2022, an EM survey was completed over E80/5241 at the Kiwirrkurra Project. The aim of the survey was to help identify electrical conductor anomalies potentially related to massive sulphide mineralisation in bedrock. The survey data will also assist with regolith thickness mapping, mapping of deep weathering zones along structures or alteration zones, and potential mapping of disseminated sulphides in areas of sub-crop to outcrop. A preliminary high-level summary with observational comments on the results of the survey was recently completed by independent consultant Resource Potentials Pty Ltd. Two (2) rank-3 anomalies were outlined in early time-decay channel data in the western part of the survey area (Pokali) and correlate to areas of sub-crop/outcrop and interpreted faults and are also semi-coincident with existing priority targets defined by gravity and magnetic anomaly highs and copper-gold geochemical anomalism. The western anomalies also exhibit typical induced polarisation effects which could be attributed to near-surface disseminated sulphides within sub-crop/outcrop, and both anomalies require field reconnaissance and more detailed analysis. The eastern survey area appears to be dominated by electrically conductive paleochannel responses, however there are semi-isolated and highly conductive zones within these paleochannel zones that occur in the later AEM time-decay channel data, and which do not decay out.
One of these highly conductive zones is semi-coincident with an existing high-priority target defined by high gravity and magnetic anomalism and requires further analysis. It's uncertain however if these highly conductive zones are related to thicker conductive cover or semi-isolated pods of saline groundwater within the interpreted paleochannel zones, or if they could be related to electrically conductive sulphide mineralisation or graphite, and further work is recommended including geochemical sampling or shallow aircore drilling. Detailed mapping and additional rock-chip sampling will commence at Pokali from April 2023 following the recent completion of a heritage survey over the Pokali Prospect area. The mapping and rock chip sampling programs over the outcropping Pokali system will help to better understand the structural and lithological controls to known mineralisation and combined with the a new understanding of the geochemistry and metal zonation, will help tightly constrain existing and new drill targets on the area of outcrop. Learnings about stratigraphy, structure and geochemistry that are gleaned from the mapping and surface sampling exercises will also inform interpretations for future drilling through transported cover within the broader Pokali area. These programs follow the recent recognition of two mineral systems at Pokali; a large copper (Cu) - gold (Au) bearing mineral system in the east of Pokali and a second tin (Sn) - tungsten (W) bearing mineral system in the west.
