Gateway Mining Defines 4km Gold Anomalies at Glenburgh South
Key Takeaways
- Gateway has defined two coherent gold-in-soil anomalies at Glenburgh South, each extending about 4km, from 338 soil samples assayed at ALS in Perth.
- Absolute values are low, with a peak of 8 ppb, a mean of 0.28 ppb and a median of 0, so the case rests on scale and continuity rather than grade.
- The 200m x 800m sampling grid is wide, and management expects infill sampling to pinpoint stronger zones within the new targets.
- A $45 million placement funds planned 2025 and 2026 exploration, with Cowza RC assays at Yandal due shortly as the next catalyst.
- No drilling is reported, and the next steps include mapping, rock-chip sampling and infill soils before first-pass drill targets are generated.
Gateway Mining defines two 4km gold-in-soil anomalies at Glenburgh South
Gateway Mining (ASX: GML) has received the first assay results from its regional soil sampling program at the Glenburgh South Project in Western Australia’s Gascoyne region. The results define two coherent gold-in-soil anomalies, each extending for approximately 4km of strike.
The anomalies coincide with interpreted regional structural corridors identified through recent geophysical interpretation. Gateway says the results represent the first systematic geochemical testing of priority structural corridors at Glenburgh South.
The project sits within the Glenburgh Gold District, immediately south of Benz Mining Corp’s (ASX: BNZ) Glenburgh Gold Project. For investors, that location is the core of the story: Gateway is testing ground next to a neighbour whose exploration success the company says has highlighted the district’s prospectivity.
Gateway also noted it remains extremely well capitalised to undertake planned 2025 and 2026 exploration, following completion of its recent $45 million placement.
Management comment
Chief Executive Officer Richard Pugh was candid that the gold values are low, while pointing to the size and consistency of the pattern.
Richard Pugh, Chief Executive Officer
“While the absolute gold values are modest, the samples were collected over a very wide spaced 200m x 800m sampling grid. The scale and continuity of the anomalism is very encouraging for an early-stage, first-pass regional program… Infill sampling can likely pinpoint zones of stronger anomalism within the newly defined target areas.”
Put simply, a wide grid can miss smaller, richer zones between sample lines. This is an early-stage, first-pass result, not a drill result.

What the soil results show
The program collected 338 surface soil samples using a -177um sieve, meaning only fine material below that size was kept. Samples were submitted to ALS in Perth for gold analysis. The peak result was 8 ppb gold (parts per billion), and the anomaly threshold on the announcement’s figures is >3ppb Au.
The summary statistics from Appendix A show how low most readings were:
| Statistic | Au (ppb) |
|---|---|
| Maximum | 8 |
| Mean | 0.28 |
| Median | 0 |
The announcement’s Appendix A also lists percentile figures, but the labels and values are jumbled in the source layout, so they are not reproduced here. The median of 0 tells you most samples read at or below detection level, which is why the clustering of higher readings along strike matters.
Figures 1 and 2 in the announcement map the anomalies against regional structures. The announcement describes each as extending approximately four kilometres.
Why modest values still matter
Gold-in-soil geochemistry measures tiny traces of gold in surface material to point towards mineralisation below. The announcement notes the subdued geochemical response often associated with large gold systems occurring beneath weathered cover.
That shapes how you should read the numbers. At the reconnaissance stage, the investment angle is scale and continuity rather than peak grade. No drilling is reported in this announcement, so these results are an exploration lead and nothing more.
The tenure history adds context. The announcement notes that Normandy’s 1994-95 exploration identified an anomalous 13-kilometre surface gold anomaly on an identical structure to the one that hosts the 510Koz Glenburgh gold deposit.

Next steps and what investors can watch
Gateway’s immediate focus, as listed in the announcement, is:
- Completing geological mapping and rock-chip sampling across the newly identified anomalies.
- Completing soil sampling across two additional target areas.
- Receiving and interpreting additional soil assay results.
- Undertaking infill soil sampling where warranted.
- Further refining the structural interpretation of the project area.
- Integrating geochemical, geological and geophysical datasets.
- Generating priority targets for first-pass drill testing.
Additional assay results from the current anomaly areas and the two remaining target areas are expected over the coming months.
Pugh pointed to Benz Mining’s discoveries as leading to a current market capitalisation of ~$1.8 billion. That is the CEO’s comparison for the district’s prospectivity, and it does not suggest Gateway can replicate it.
Yandal Gold Project update
Gateway also updated investors on its flagship Yandal Gold Project:
- One RC rig is drilling at Cowza.
- One aircore rig is testing some of the higher priority splay structure targets.
- The arrival of the first diamond rig has been delayed until next week.
- The company expects to release assays shortly from the next batch of RC drilling at Cowza.
Those Cowza assays offer a near-term news flow catalyst alongside the Glenburgh South results.
The Cowza gold discovery at Yandal has already been traced over 3.5km of continuous mineralisation, which is why the next batch of RC assays is being watched closely by the market.
Gateway holds an 80% interest in the main Glenburgh South tenements (20% free carried by the original vendors until a definitive feasibility study, with a 1.0% Gross Return Royalty to Quinn Royalty Pty Ltd), and 100% of three tenements currently in application.
