Recent drilling at Gateway Mining's Yandal Gold Project in Western Australia has revealed expanding gold mineralisation at multiple prospects, suggesting a growing potential for significant resource development.
The Mustang prospect, a key area within the Yandal package, has seen its defined strike length extended to at least 900 meters. Latest results from shallow depths, including an 8-meter core interval assaying 2.1 grams per tonne gold, push high-grade mineralisation 500 meters further into an area previously considered under-drilled. Gateway's interpretation indicates that earlier drilling to the north may not have sufficiently tested eastward, where newly identified structures are now being explored. This development positions Mustang as a significant second discovery front for the company within the Yandal camp.
Further within the Yandal project, the Great Western prospect has consistently yielded results, with surface gold anomalism now spanning an impressive 11.5 kilometers. Previous discoveries include the retrieval of 328 new gold nuggets and earlier finds of 134 nuggets totaling 366 grams. These findings have identified additional key locations along the western edge of a structure known as the Great Western Intrusive, adjacent to the Great Western shear. This work extends the known gold occurrences across the Great Western splay corridor.

Another parallel gold target, named Rubicon, has been identified sitting on a structure east of the Haflinger discovery and along the same Mustang Trend. Initial, widely spaced drilling at Rubicon has defined gold mineralisation over 700 meters of strike. Headline intercepts include 12 meters grading 1.0 g/t gold, with a notable 4-meter section returning 2.6 g/t gold from 72 meters. This Rubicon discovery adds a third gold prospect along the Celia-Mustang structural corridor.
The company has also focused on the Hummer prospect, unveiling shallow gold mineralisation just west of the Haflinger discovery. Early aircore drilling, targeting a structural splay off the Celia Shear Zone, suggests this area could host enhanced dilation and potentially higher-grade gold as drilling progresses. Gateway has described the systematic exploration approach through the Celia-Mustang area as "continuing to yield very significant results."

Exploration efforts have also involved advanced geophysical techniques. Induced-polarisation (IP) surveys have been utilized to refine targets across the Yandal project, particularly at the Dusk 'til Dawn deposit and its northern intrusion, the Comanche prospect. These surveys have indicated resistivity anomalies and increased chargeability, which are consistent with mineral sulfides and geological features often associated with gold mineralisation, especially in areas adjacent to intrusions and fault intersections.
Earlier in the company's exploration cycle, the acquisition of Strickland Metals' Yandal Project, which contained a reported 400,400 ounces of gold, expanded Gateway's footprint. This acquisition included targets with signatures typical of large intrusion-related gold systems (IRG), characterized by gold-molybdenum-copper-bismuth-tellurium anomalies and specific alteration patterns. IRG systems are known for their potential to host substantial gold resources across large volumes.
The Yandal Gold Project is situated within the prolific Yilgarn Craton of Western Australia. Gateway Mining's strategy involves systematically exploring this region, with recent activities accelerating the definition of discoveries like Haflinger and preparing for subsequent drilling phases. The company has emphasized the geological context of the Yandal camp, where mineralised gold veins often develop along sheared contacts between different volcanic and intrusive rock units.
