6 January 2026 – Perth, Australia | Locksley Resources Limited (ASX: LKY / OTCQX: LKYRF / FSE: X5L) has today announced the identification of a high-grade, northwest to southeast oriented mineralised silver corridor at its Mojave Project in California in the United States, marking a significant advancement in the Company’s exploration strategy for the Project.
Reconnaissance and surface rock chip sampling has confirmed high-grade silver mineralisation extending almost 3 kilometres from the initial high-grade silver discovery, located ~320 metres southwest of the historic Desert Antimony Mine (DAM). Assay results include values of up to 409g/t silver, with twelve rock chip samples exceeding 30g/t silver, reinforcing the precious metal potential within the Mojave Project’s North Block.
In addition to silver, the results confirm a strong polymetallic system, with significant base metal mineralisation recorded. Samples returned grades of up to 4.2% copper, 1.5% lead and 1.5% zinc, highlighting the multi-commodity nature of the mineralised corridor and enhancing the overall prospectivity of the project area.
The interpreted mineralised corridor was announced to extend approximately 2.4 kilometres west-northwest of the historic Hendricks Shaft and around 600 metres to the east-southeast, which suggestss the presence of a large-scale hydrothermal system. High-grade samples collected from outcropping veins and historic stockpiles display gossanous textures and boxwork structures, indicating weathered sulphide-rich polymetallic veins and the potential for fresh sulphides at depth.
A total 398 rock chip samples have been collected across the North Block, with around 260 samples taken along the interpreted corridor between the Desert Antimony Mine and areas up to 5.6 kilometres to the southeast. Additional notable results include a sample returning 117g/t silver and 3.1% copper, collected near historic workings where copper carbonate mineralisation is visibly present.
Kerrie Matthews, Managing Director & CEO, commented: “Defining a 3km mineralised trend with surface results of up to 409 g/t silver and 1.5% copper is a highly encouraging outcome. Importantly, this discovery complements our core antimony development strategy and gives exposure as a diversified U.S. critical minerals company, providing shareholders with upside to precious metals, base metals, and strategic minerals within a single, high-quality project area.”
Locksley plans to advance this silver and base metals opportunity through a systematic exploration program, to be undertaken in parallel with ongoing activities at the Desert Antimony Mine and El Campo prospects. Planned work includes detailed geological mapping, petrological and geochemical studies, assessment of suitable geophysical surveys, and the delineation of high-priority, drill-ready targets along the mineralised trend.

ABOUT LOCKSLEY RESOURCES LIMITED
Locksley Resources Limited is focused on critical minerals in the United States of America. The Company is actively advancing the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley is executing a mine-to-market strategy for antimony, aimed at re-establishing domestic supply chains for critical materials, underpinned by strategic downstream technology partnerships with leading U.S. research institutions and industry partners. This integrated approach combines resource development with innovative processing and separation technologies, positioning Locksley to play a key role in advancing U.S. critical minerals independence
MOJAVE PROJECT
Located in the Mojave Desert, California, the Mojave Project comprises over 491 claims across contiguous prospect areas, namely, the North Block/Northeast Block and the El Campo Prospect. The North Block directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials’ claims, highlighting the strong geological continuity and exploration potential of the project area. In addition to rare earths, the Mojave Project hosts the historic “Desert Antimony Mine”, which last operated in 1937. Despite the United States currently having no domestic antimony production, demand for the metal remains high due to its essential role in defense systems, semiconductors, and metal alloys. With significant surface sample results, the Desert Mine prospect represents one of the highest-grade known antimony occurrences in the U.S. Locksley’s North American position is further strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE & antimony production. With its maiden drilling program planned, the Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security
