Highlights
- Tempest Minerals has been advancing exploration momentum across its Yalgoo and Range Projects in Western Australia.
- New iron mineralisation potential identified at the Halo Target near the Remorse deposit.
- Geological mapping and reinterpretation enhance targeting at the Range project.
- Rock chip sampling returned up to 1g/t gold over a 1km strike at Range.
- December quarter work to focus on assay results and project advancement.
Tempest Minerals Ltd (ASX:TEM) continued to advance its gold and iron exploration programs through the September 2025 quarter, with key developments across its Range and Yalgoo Projects in Western Australia.
Yalgoo Project: New Iron Targets and Heritage Survey
At the Yalgoo project, the company’s flagship asset in Western Australia, work focused on expanding the understanding of iron mineralisation following the Remorse magnetite deposit discovery in 2024. A detailed data review of the surrounding geology highlighted additional potential at the Halo Target, situated approximately 5km west of Remorse. Historical records indicate iron-rich rock chips in the Halo area, supporting the prospectivity for further discoveries.
A heritage survey over the project area was completed during the quarter.
Fieldwork Expands at Range Project, Mount Magnet
At the Range Project, located 5km along strike from the +6Moz Mount Magnet operations, Tempest conducted a comprehensive geological mapping and reinterpretation exercise. External consultants were engaged to refine structural and stratigraphic understanding of the 20km² project area. This work has resulted in an updated geological model that aligns more closely with the Mount Magnet and Boogardie Basin geology, providing a stronger context for upcoming exploration efforts.
Rock chip sampling returned multiple gold results up to 1g/t Au over a strike length of approximately 1km. The mineralisation was identified within north-east striking fractured quartz veins exhibiting sulphide and siderite alteration — geological characteristics similar to those seen at the nearby Britannia Well open pit and Boogardie Break mineralisation zones.
Gold Exploration with New Drilling Program: To extend known targets and identify new anomalies, Tempest initiated a large-scale auger geochemical sampling program across the southwestern portion of the Range project. Concurrently, preparations were finalised for the inaugural 1,500m reverse circulation (RC) drilling program, targeting multiple gold prospects, including Wrangler (a potential extension to the Britannia Well mineralisation) and Cherokee, which has recorded 1g/t gold at surface.
Following the quarter-end, Tempest announced on 20 October 2025 that its first gold-focused drilling program at the Range Project was completed. Samples have been dispatched for laboratory analysis.
Outlook: Continued Exploration into December Quarter
In the December 2025 quarter, Tempest plans to maintain exploration momentum through:
- Completion and interpretation of RC drilling data from the Range Project
- Integration of mapping and geochemical results to refine new target areas
- Ongoing development of the Yalgoo project, including follow-up exploration at the Halo and Remorse magnetite targets
Tempest remains focused on advancing both gold and iron exploration across its Western Australian portfolio through systematic fieldwork and data-driven targeting.
