Sanity Prospect’s Extended Gold Anomaly Raises Stakes Ahead of Drilling
Tempest Minerals has refined and extended the gold anomaly at its Sanity Prospect within the Yalgoo Project through denser geochemical sampling, boosting confidence in a potentially large mineralised system.
- Geochemical sampling density increased from 200m to 100m grid
- Gold soil samples peaked at 294ppb, confirming anomaly continuity
- Sanity Prospect lies within an extended Yalgoo Greenstone belt
- Plans underway for geological modelling and drilling approvals
- Multiple mineralisation types identified including gold, base metals, and iron
Enhanced Sampling Sharpens Gold Footprint
Tempest Minerals Ltd (ASX: TEM) has announced a significant update on its Sanity Prospect, part of the broader Yalgoo Project in Western Australia. By increasing the density of geochemical soil sampling from a 200m by 200m grid to a tighter 100m by 100m grid, the company has achieved a clearer and more continuous definition of the gold anomaly previously identified in the area. Soil samples have returned gold concentrations up to 294 parts per billion (ppb), reinforcing the prospectivity of the site.
Strategic Location within Yalgoo Greenstone Belt
The Sanity Prospect is situated within what Tempest describes as a previously unrecognised extension of the Yalgoo Greenstone belt, a geological formation known for hosting world-class gold, base metal, and iron ore deposits. This extension was identified through innovative data analysis and now forms part of Tempest’s dominant regional holdings exceeding 1,000 square kilometres. The project area also includes the Remorse Magnetite deposit and lies adjacent to the Barron Rothchild gold deposit, underscoring the region’s mineral potential.
Robust Multi-Element Geochemical Anomaly
The enhanced sampling has delineated a coherent gold anomaly that correlates strongly with geophysical features such as magnetic highs and lows. Alongside gold, silver shows a similar geochemical dispersion pattern, adding robustness to the findings. Rock chip samples from nearby historical workings have yielded high-grade gold up to 7 grams per tonne and significant copper and iron values, aligning with the regional exploration targets for multiple metals.
Next Steps Toward Drilling
Tempest is currently assessing the new data in the context of regional geology and is progressing regulatory approvals for further exploration activities. The company plans to develop detailed geological models and aims to initiate a drilling program subject to the outcomes of ongoing assessments. The approved Program of Work (POW) for the target area facilitates this next phase, which may include a combination of geophysical surveys and various drilling techniques to better understand the mineralisation at depth.
Building on a Track Record of Discovery
This announcement builds on Tempest’s recent successes in the region, including the 2024 discovery of the Remorse Magnetite deposit. The company’s systematic and data-driven approach to exploration in this underexplored portion of the Yalgoo Greenstone belt continues to uncover promising mineralisation, positioning it well for future resource development.
Bottom Line?
With drilling approvals on the horizon, Tempest’s refined Sanity anomaly could soon reveal the true scale of its gold potential.
Questions in the middle?
- How will upcoming drilling results confirm the size and grade of the Sanity gold system?
- What are the timelines and regulatory hurdles for Tempest’s planned drilling program?
- Could the multi-element anomalies indicate additional base metal or iron resources beyond gold?
