Tempest Expands Sanity Gold Anomaly at Yalgoo Project

21 May 2025 | Mt Hawthorn, WA – Tempest Minerals (ASX:TEM) has significantly expanded the surface footprint of its Sanity gold anomaly at the Yalgoo Project in Western Australia, following results from a tighter-spaced geochemical sampling program.

Soil sampling on a 100m x 100m grid returned up to 294ppb gold, outlining a stronger and more coherent anomaly adjacent to historical mine workings. The Sanity prospect continues to build as a compelling target for future drilling.

Key Highlights:

• Peak soil value: 294ppb Au, with a strong gold-silver geochemical correlation

• Rock chips nearby returned up to 7g/t gold, 0.2% copper, and >60% iron

• Geophysical data highlights a coincident magnetic anomaly and structural distortion

• Over 200 samples define a robust multi-element geochemical anomaly

Next Steps:

• Assess results within regional geological context

• Advance approvals and develop geological models

• Plan for drilling and further mapping, geophysics, and sampling

Managing Director Don Smith commented:

“The expansion of the Sanity anomaly adds weight to the prospectivity of the Yalgoo Project. This is a clear example of our data-driven approach delivering strong regional targets ready for drill testing.”

Tempest controls more than 1,000km² in the Yalgoo region, and Sanity joins a growing list of prospects alongside the 2024 Remorse magnetite discovery.
