Highlights
- Tempest Minerals has confirmed extension of gold anomaly at the Sanity Prospect through higher-resolution geochemical sampling.
- Increased sampling grid density has revealed a more coherent and continuous gold anomaly.
- Enhanced data increased confidence in Sanity Prospect’s large-scale potential.
- The company is assessing results for potential drilling, with geological modelling and exploration approvals in progress.
Tempest Minerals Ltd (ASX:TEM) has shared an update on exploration activities at the Sanity Prospect, a prospective target within the Yalgoo Project in Western Australia. Recent geochemical sampling at the prospect has confirmed and further defined a previously identified gold anomaly, with soil samples returning values of up to 294 parts per billion (ppb) gold.
Sampling efforts at the Sanity Target have intensified, with grid spacing tightened from 200m by 200m to 100m by 100m. This tighter sampling grid has significantly improved the resolution of the geochemical sampling data, revealing a more defined and continuous gold anomaly across the prospect area.
The enhanced dataset has boosted confidence in the potential of the Sanity Prospect, reinforcing the potential for a large-scale mineralised gold system.
Background: Yalgoo Project and Sanity Prospect
The Yalgoo Project includes an extension of the Yalgoo Greenstone Belt, a previously unrecognised structure identified through advanced data analysis. This belt lies within the company’s 100%-owned Yalgoo regional holdings, which are adjacent to several world-class gold, base metal, and iron ore deposits.
Following the discovery of easterly extensions to the belt, Tempest expanded its landholding to over 1,000 km². The first-ever systematic exploration across this area led to multiple mineralisation discoveries, including the identification of the >4 km Remorse Magnetite deposit.
Additionally, surface sampling and geological mapping to the south identified the Sanity gold target, which appears as a localised distortion in geophysical datasets. It aligns with a multi-element geochemical anomaly identified in over 200 collected samples.
In the Sanity Target, soil sample values peaked up to 294 ppb gold. The anomaly displays a geometry consistent with adjacent geophysical features, and gold-silver exhibit similar geochemical dispersion, further highlighting the anomaly’s integrity.
Rock chip sampling from nearby historical workings revealed high-grade mineralisation, including up to 7 g/t gold, 0.2% copper, and over 60% iron. These results conform to the regional exploration targets for gold, iron, and base metals.
Next Steps
- Assessment of results to determine drilling potential is underway.
- Approvals for future exploration and geological modelling are in progress.
- A targeted drilling program is being planned, pending final evaluations.
