Early Drilling Success at Mt Magnet Raises Questions on Resource Scale and Development
Tempest Minerals has reported promising gold assay results from its latest drilling at the Range Gold Project near Mt Magnet, confirming mineralisation continuity over a significant strike length.
- 19-hole RC drilling program completed for 1,500m
- Gold mineralisation intersected over 1.5km strike length
- Notable intercepts include 3m at 1.9g/t Au from 13m and 2m at 1.2g/t Au from 21m
- Mineralisation hosted in felsic porphyry intrusions typical of Boogardie Basin
- Proximity to existing open pits and Ramelius Resources processing expansion
Exploration Progress at Mt Magnet
Tempest Minerals Ltd (ASX, TEM) has delivered encouraging results from its recent Reverse Circulation (RC) drilling campaign at the Range Gold Project, situated near the established Mt Magnet gold mining district in Western Australia's Murchison region. The program, completed in October 2025, comprised 19 drill holes totaling 1,500 metres and targeted multiple prospective zones across the project area.
The drilling has intersected gold mineralisation over an approximate 1.5-kilometre strike length, a significant extension that supports the presence of a larger mineralising system. Highlight intercepts include 3 metres grading 1.9 grams per tonne (g/t) gold from 13 metres depth and 2 metres at 1.2 g/t gold from 21 metres. These results are consistent with previous assays, such as 3 metres at 3.2 g/t gold from 58 metres, indicating a continuity of mineralisation both near surface and at depth.
Geological Context and Strategic Location
The mineralisation is hosted within silica-sericite-pyrite altered felsic porphyry intrusions, characteristic of the Boogardie Basin geology. This geological setting is known to host significant gold deposits in the Mt Magnet region, a well-established multi-million-ounce gold province with active large-scale open pit and underground mining operations.
Importantly, the Range Project lies adjacent to existing open pits and is less than 10 kilometres from Ramelius Resources’ planned major processing circuit expansion. This proximity to established infrastructure could enhance the economic viability of any future resource development at Range.
Next Steps and Outlook
Tempest Minerals plans to review the latest drilling results alongside geological modelling to refine target zones. Further work is anticipated, including additional drilling to test lateral and depth extensions of the mineralised system. Results from a recent geochemical sampling program are also awaited, which may provide further insights into the project’s potential.
While the drilling spacing remains reconnaissance and true widths of mineralisation are yet to be defined, these early-stage results are promising. They align with grades and scales reported by neighbouring operators, suggesting the Range Project could become a meaningful contributor within the Mt Magnet gold district.
Bottom Line?
Tempest’s latest drilling confirms a compelling gold system at Range, setting the stage for expanded exploration and potential resource growth.
Questions in the middle?
- What will the upcoming geochemical results reveal about the broader mineralisation?
- How will Tempest prioritise targets for follow-up drilling to define resource potential?
- Could proximity to Ramelius Resources’ processing expansion accelerate project development?
