Multiple Gold Discoveries Driving a Strong Re-Rating Opportunity
We are revising our target share price for Gateway Mining (ASX: GML)to $0.16, implying 142% upside from the current share price of $0.07, following our Initiation Report from October 2025. GML is a Western Australian gold explorer advancing the Yandal Gold Project, where it now holds a Mineral Resource of 8.17Mt @ 1.52g/t Au for 400koz across Horse Well and Dusk ’til Dawn. The project is strategically located within the Yandal Greenstone Belt, approximately 50km from Northern Star’s Yandal production centre, one of the most established gold mining hubs in Western Australia. Since the last update, the outlook has strengthened through the commencement of systematic drilling at Great Western, the emergence of Haflinger as a meaningful shallow gold discovery, and the identification of Hummer and Rubicon as additional mineralised prospects within the Celia-Mustang corridor. Gateway’s strong balance sheet also supports continued multi-front exploration through 2026. These developments improve the risk-reward profile by supporting future resource growth.
Great Western Advances from Target Generation into Active Drill Testing
Great Western is a key de-risking development because the prospect has progressed from surface anomalism into systematic drill testing. Early work defined an 11.5km gold-in-soil anomaly supported by repeated nugget occurrences along a sheared corridor, while follow-up mapping identified a differentiated dolerite host, strong structural complexity, and geological similarities to major Eastern Goldfields deposits such as Jundee and Junction. Gateway has now commenced the first systematic drill program at Great Western, initially targeting the 7km outcropping portion of a system with an apparent 16km strike extent in magnetic data. At this stage, the significance lies not in assay delivery but in the progression from target generation to direct drill testing.
Celia-Mustang Support an Emerging Multi-Prospect Growth Corridor
The Celia–Mustang corridor is emerging as a key growth driver for Gateway, with mineralisation now identified across multiple nearby structures rather than being confined to a single target. Haflinger highlights the presence of a shallow, open-ended system, while Hummer and Rubicon demonstrate that mineralisation extends along parallel trends within the broader corridor. Collectively, this supports the interpretation of a larger, camp-scale gold system, with meaningful potential for further discoveries and resource growth as exploration continues.
Strong Balance Sheet and Aligned Management
Gateway’s broader growth profile is underpinned by a strong balance sheet, providing the financial flexibility to advance multiple exploration targets in parallel without near-term funding pressure. This is complemented by an experienced management team with strong shareholder alignment, highlighted by Chairman Andrew Bray holding a ~9.8% stake in the company. This management ownership reinforces confidence in disciplined capital allocation and long-term value creation, ensuring that management’s incentives remain closely aligned with shareholders as the company continues to progress.
Stock Rerating Driven by New Discoveries
Following recent milestones, we value GML at $0.15 in our base case (~132% upside) and $0.17 in our bull case (~152% upside), relative to the current share price of $0.07. Using the midpoint of these scenarios, our A$0.16 target implies 142% upside. Gateway’s rerating case is supported by its Resource at Yandal, emerging discovery momentum at Great Western and across the Celia-Mustang corridor and a strong funding position to support parallel exploration, resource growth, and further de-risking.
