• Structural mapping expands target mineralised corridor at Desert Antimony Mine (DAM) fourfold to 1.2 km
• New parallel structural target zone identified 150m west of the main DAM structure
• Updated 3D geological model defines seven priority follow up surface sampling targets

Locksley Resources Ltd has announced a major advancement at its Mojave Project in California. Recent structural mapping has dramatically expanded the target mineralised corridor at the Desert Antimony Mine (DAM) Prospect and identified a parallel structural target, enhancing the potential for a larger mineralised system across multiple mineralised zones. The structural geology mapping completed in late August/September 2025 has expanded the strike extent of the target structure at the DAM Prospect from 0.3 km to 1.2 km, representing a ~400% increase and highlighting the potential of the system. Mapping confirmed the continuity of the NNE-striking structural zone that hosts high-grade stibnite mineralisation at DAM, and identified a second, parallel shear zone, approximately 150 m to the west, exhibiting similar alteration and structural characteristics. The updated geological interpretation also highlights steep north-plunging intersections between the mapped shear zones and folded host rocks as possible mineralisation plunge controls. These findings have been incorporated into a new 3D geological model, which has defined seven priority surface sampling targets to guide the next phase of exploration and support the development of a JORC Exploration Target to guide future drilling programs. The scale and geometry of these target zones align with the type of high-grade, clean stibnite feedstock required to fast-track U.S. antimony supply chains. Mapping at the Hendricks Prospect, 2.5km south east of DAM, has also returned high-grade silver assays of up to 216g/t Ag, alongside anomalous Zn, Pb, and Cu, indicating a broader polymetallic system. First pass mapping at the Junipero Prospect, 1.1km north of the Mountain Pass Mine, has identified multiple E-W trending lamprophyre dykes, highlighting potential for additional critical mineral occurrences including carbonatites.

The expanded target at Mojave has the potential to strengthen the project's position as a strategic U.S. critical minerals hub, aligned with accelerating domestic supply-chain initiatives. A third phase structural mapping program is scheduled to commence in late November 2025 to continue building geological understanding of the project and identify new targets.
