Announcement
Taiton Resources Limited (ASX: T88) has released a strong exploration update covering its Highway and Challenger West projects in South Australia, marking important progress on both gold and critical minerals fronts (Figure 1). The latest results highlight standout gold-in-soil values from Challenger West — including the highest recorded to date — alongside further definition of rare earth element (REE) anomalism at the Yogi prospect within the Highway Project.

Together, these outcomes underscore the company’s methodical approach to advancing two highly prospective targets with distinct commodity exposures. With heritage surveys about to commence, Taiton is positioning itself for a busy and potentially transformative second half of 2025, as it moves toward drilling programs aimed at converting these surface anomalies into significant mineral discoveries.
Highlights - Shear-Hosted Gold, IOCG and Carbonatite.
Challenger West Gold Project: Infill Ultrafine (UF) soil sampling at Area 1 returned the highest gold-in-soil result to date – 210 ppb Au – within a 1.5km gold anomalous zone coincident with interpreted NNE-trending structures (Figure 2).

Highway Project – Yogi Prospect: Surface geochemical anomalism in REEs aligns with a >6 mGal gravity anomaly, supporting an IOCG/carbonatite-hosted REE exploration model (Figure 3).

Heritage Surveys: Commencing mid-August to support Exploration Program for Environment Protection and Rehabilitation (EPEPR) applications for planned drilling.
Challenger West – Infill Soil Sampling Delivers Peak Gold Values
A 245-sample infill UF soil program on a 50m x 50m grid at Area 1, Challenger West, has defined a 1.5km gold-in-soil anomaly along interpreted NNE-trending structures (Figure 3).

The program returned the project’s best gold-in-soil result to date – 210 ppb Au.
Discrete higher tenor gold zones will be prioritised in upcoming drill programs.
Challenger West sits 10km west of the 1.2Moz Challenger gold deposit, where mine infrastructure remains on care and maintenance and is under review for potential restart by Barton Gold Holdings (ASX: BGD). The target style is similar to Challenger’s narrow plunging lodes within the Christie Gneiss.
Highway Project – Yogi Prospect Strengthens IOCG/Carbonatite-REE Case
First-pass UF soil sampling (59 samples, 200m x 400m spacing) across the Yogi gravity anomaly confirmed (Figure 4):
Low-level but broad REE anomalism coincident with the anomaly.
Dominance of light rare earth elements (LREE) over heavy rare earth elements (HREE), consistent with typical carbonatite signatures.

The Yogi gravity anomaly measures over 6 mGal on a 1.5km strike within a broader 4 mGal zone across 5km of strike. Its dense source body may represent iron oxide minerals or carbonate-rich carbonatites, supporting the IOCG/REE potential.
At the Yogi prospect within the Highway Project, first-pass Ultrafine soil sampling has outlined broad, low-level REE anomalism coincident with a >6 mGal gravity anomaly over a 1.5 km strike, with this alignment supporting its IOCG exploration potential (Figure 5).

As shown in Figure 6, the REE anomalism is LREE-dominant and aligns with the gravity contours, consistent with IOCG or carbonatite-hosted REE systems, reinforcing the target’s prospectivity ahead of drilling.

The Highway lies within the Gawler Craton, host to major IOCG deposits such as Olympic Dam and Carrapateena. Geochronology shows the area was tectonically active during the Olympic Metallogenic Event.
Next Steps
Heritage surveys at both Challenger West and Highway.
Submission of remaining soil samples for analysis.
Preparation for drill programs targeting the highest tenor anomalies.
Executive Director David Low commented:
“We are very pleased with soil results at Challenger West where strong tenor gold (up to 210 ppb Au) coincident with interpreted NNE trending structures gives us great confidence we are on the right path.
The results at Yogi continue to build the IOCG / Carbonatite hosted REE target and we know the real proof will be in drilling the gravity anomaly. With heritage surveys commencing mid-month, Taiton is looking to have an exciting second half to the year with drilling planned to come.”
Samso Concluding Comments
Declaration: I am the co-founder, shareholder and current Non-Executive Director of Taiton Resources Limited.
Taiton Resources’ work at Challenger West and Yogi is steadily building a dual-commodity exploration story with genuine scale potential. Taiton is potentially developing a Shear-Hosted Gold, IOCG and Carbonatite narrative as it starts work on testing the targets at Challenger West and the Highway project.
The 210 ppb gold-in-soil result at Challenger West is the highest recorded to date and sits within a well-defined structural corridor, giving the planned drilling program clear focus.
What is significant about the Challenger soils is that the line of purple soil results in Figure 3 will be a very interesting spot when drilling occurs. Most exploration geologists would be happy with those numbers, even in soils. It is noteworthy to remember that the broad-spaced calcrete sampling that started the discovery of the Challenger Gold Mine had a value of 180ppb.
I know it is calcrete, and there is another discussion on how the numbers compare, but I think the anomalous nature of the number speaks for itself. Check out "Challenger Gold Prospect, Gawler Craton, South Australia - Lintern, M.J. (CRC LEME)"
At Yogi, the combination of REE anomalism and a significant gravity feature, as illustrated in Figure 4, is a classic signature for IOCG or carbonatite-style systems. The dominance of light rare earths further strengthens the geological model and positions Yogi as a compelling REE target. The Yogi target has to be one of the most interesting projects that I have come across.
The gravity target that Taiton has been showcasing over the last few months is very convincing. We all know about geophysical targets, but the degree of density of the target makes you wonder a lot, and the more red wine one has, the more mesmerising it gets. Management is keen to test that target, so let's see what that brings up as a story.
These two fronts provide exposure to both gold and critical minerals, offering a balanced exploration profile that can capture market interest across different commodity cycles.
With heritage surveys now in motion, the next phase of drilling will be the real test of whether these surface anomalies can translate into substantial mineralisation at depth.
