Gateway Mining Extends Cowza Gold System to 4.5km as High-Grade Hits Continue
Gateway extends Cowza gold system to 4.5km as high-grade hits continue at Celia South
Gateway Mining Ltd has extended the Cowza gold discovery by approximately 1km, taking the continuous high-grade gold mineralisation zone from 3.5km to 4.5km of strike. Mineralisation remains open along strike and at depth. Separately, the Celia South prospect now shows gold over 1.5km of continuous strike within the same Celia Shear Corridor. Cowza has grown substantially since the initial discovery announced on 22 June 2026 — this is a major expansion of an existing system. The company held $15.1 million in cash and liquid securities at the end of the June 2026 quarter, providing funding for planned 2026 exploration.

Cowza grows to 4.5km of continuous gold mineralisation
Step-out aircore drilling to the north has delivered further high-grade intercepts and extended the Cowza system by approximately 1km. Key intercepts include CSAC0066: 8m @ 2.1g/t Au from 84m, CSAC0073: 8m @ 1.6g/t Au from 80m, and CSAC0054: 8m @ 1.1g/t Au from 36m. Mineralisation remains open along strike and at depth.
The strongest results continue to be associated with the same favourable mafic-intermediate contact and structurally complex corridor that has consistently delivered high-grade gold intersections across the trend. This geological continuity signals system fertility — you are not looking at isolated pods of mineralisation but a connected hydrothermal system with scale potential. Rare continuity over 4.5km points to an emerging gold camp, not a single discrete target.
| Hole ID | Intercept | Grade (g/t Au) | From (m) | Prospect |
|---|---|---|---|---|
| CSAC0066 | 8m | 2.1 | 84 | Cowza |
| CSAC0073 | 8m | 1.6 | 80 | Cowza |
| CSAC0054 | 8m | 1.1 | 36 | Cowza |
| CSAC0085 | 4m | 2.0 | 124 | Cowza |
| CSAC0061 | 12m | 0.3 (incl. 4m @ 0.7g/t) | 80 | Cowza |
High-grade gold shoots emerge at Celia South
Celia South now shows gold mineralisation over 1.5km of strike, with drilling confirming high-grade gold shoots within the broader system. The standout intercept is CSAC0101: 4m @ 9.7g/t Au from 60m (within a broader interval of 28m @ 1.5g/t Au from 60m). This tells you the system hosts discrete high-grade zones, not just disseminated low-grade mineralisation across the full corridor width.
Multiple mineralised centres along the same regional trend support the thesis that this is a substantial new gold camp in development. What matters here is that both Cowza and Celia South sit within the same structural corridor, separated by less than 2km, and both display the same geological fingerprint: extensive alteration, shearing, quartz veining, and strong structural control.
Supporting Celia South context:
- Multiple mineralised centres identified along strike
- Mineralisation associated with favourable lithological contacts
- Shearing and quartz veining consistent with mesothermal gold systems
- Alteration assemblages typical of Yandal Belt deposits
Understanding the Celia Shear Corridor
A shear corridor is a major zone of deformation in the Earth’s crust where rocks have been fractured and displaced along a fault system. These structures act as conduits for gold-bearing fluids in hydrothermal systems, depositing gold where the right combination of temperature, pressure, and rock chemistry occurs. When geologists talk about “continuity over strike,” they mean the mineralisation extends laterally for kilometres along the structure, not just at isolated drill intercepts.
“Open at depth” means drilling has not yet found the bottom of the mineralised system — deeper drilling could reveal additional mineralisation beneath the current intercepts. This matters to investors because larger, connected systems can host bigger resources and support longer mine lives. Aircore drilling is cheap, shallow, and fast — ideal for mapping the broad footprint of a system. Reverse circulation (RC) drilling tests deeper, in fresh rock beneath the weathered zone, and delivers the grade and continuity data required for resource estimation. The Yandal Belt, where Cowza and Celia South sit, is a highly endowed greenstone terrane in Western Australia known for multi-million-ounce gold deposits. Extensive alteration and structural control are hallmarks of significant gold systems in this geology.
RC drilling underway with first assays due next month
RC drilling is ongoing at Cowza to test continuity, geometry, and depth extent in fresh rock beneath the aircore footprint. Initial RC assay results are expected next month. This is the first meaningful test of Cowza at depth and will indicate potential scale and grade distribution — a key upcoming catalyst for the stock.
Exploration roadmap:
- Aircore programme — extended Cowza strike to 4.5km (delivered)
- Celia South strike mapped to 1.5km (delivered)
- RC drilling at Cowza — testing depth and fresh rock (ongoing)
- Initial RC assays due next month
- Further step-out drilling along the corridor
Why the results matter for investors
Gateway held $15.1 million in cash and liquid securities at the end of the June 2026 quarter. The company has not stated it is fully funded for all planned 2026 exploration, but the cash position removes near-term pressure for a dilutive capital raise. This matters because you are watching a discovery grow without the risk of immediate equity dilution.
The twin discoveries at Cowza and Celia South represent multiple targets along one regional trend within the Yandal Project. Upcoming RC assays are a near-term value catalyst — they will tell you whether the high-grade aircore hits extend into fresh rock at depth, which is where you start building a resource.
Richard Pugh, Chief Executive Officer
“These latest results continue to reinforce our belief that Cowza is emerging as a major new gold system within the Yandal Project. With drilling now defining continuous gold mineralisation over approximately 4.5 kilometres of strike, Cowza has grown substantially from the initial discovery announced only in June 2026 and remains open in multiple directions. This level of continuity is rare and highlights the scale of the mineralised system we are uncovering.”

Where Gateway goes from here
Gateway has demonstrated growing scale across Cowza and Celia South, both within the same regional structural corridor. The company is well capitalised with $15.1 million in cash and liquid securities, and RC assays are imminent. Management has stated further updates will be provided in due course. The next phase of drilling will determine whether the aircore success translates into a resource-scale discovery at depth.
