Announcement PDF ASX : TEM 2023-10-16 | Multiple High Priority Targets In Regional EM Survey TEM | Yalgoo Update - Multiple High Priority Targets In Regional EM Survey Key Points ● ● ● Multiple high priority targets identified in regional EM survey Iterative processing adds evidence to several existing Tempest exploration targets Appreciable anomaly coincident with 4km Remorse base metal drill target Summary Tempest Minerals Ltd (TEM) is pleased to update the market on the company’s 100% owned Yalgoo Projects. TEM previously announced it was conducting a large-scale regional electromagnetic survey. Results received from this survey have indicated the presence of multiple anomalies and further confirm the presence of the large number exploration targets and prospectivity at the project areas. Notably an anomaly exists coincident with the 4km Remorse base metal target. TEM is continuing to process the data using different parameters and models to harvest further targets and detail. Yalgoo Background TEM’s landholding in the Yalgoo Region of Western Australia which totals more than 1,000km2 of 100% owned tenements highly prospective for base and precious metals. The project contains different geological domains referred to by four different areas – namely: Messenger, Meleya, War West, Euro though much of these have considerable geological overlap. TEM previously announced the commencement of a large scale regional EM survey across much of the central portion of the Yalgoo tenements 1. This survey in particular was to assess the Meleya and War West regions where the company has been actively exploring through data analysis, fieldwork and drilling 2. Exploration in these areas has encountered multiple zones of previously unknown mineralisation to date 3. Survey The survey was performed with the purpose of finding variances in electromagnetic responses from the project areas. Areas of greater or lesser conductivity and magnetic susceptibility can represent mineralisation but can also be influenced by the presence of water, minerals, and other materials. Tempest has proven through various methods 4 that the region is fertile for VMS (volcanogenic massive sulphide) style mineralisation which often hosts copper, zinc, lead and precious metals - as seen at the nearby Golden Grove Mine Camp 5. Some sulphide mineralization can be conductive and this style of EM survey is extensively utilised in the industry for identifying this and other types of mineralisation. The survey included over 300 lines of 200m spacing for more than 2,000 kilometres of line survey measurements.

Some areas of the survey were initially obfuscated by the presence of subsurface groundwater and Tempest has been producing iterative updated models using varying algorithms and processing techniques to mitigate this. The current reprocessed data includes numerous zones of interest for exploration and several potential high priority drill targets. Notably, among the zones detected are multiple targets coincident with existing Tempest exploration targets. This includes the presence of an appreciable EM anomaly at the exciting previously announced 4km long base metal ‘Remorse’ target 6, 7. Next Steps - Progressive iterations of the geophysical models likely to produce further targets Ground truth and investigate additional new targets Targeting commencement of drilling at Remorse in Q1 2024 Page 2 | 4 ASX : TEM 2023-10-16 | Multiple High Priority Targets In Regional EM Survey The Board of the Company has authorised the release of this announcement to the market.
