Locksley Resources (ASX: LKY) has announced the identification of a high-grade mineralised silver corridor at its Mojave Project in California, USA.
Reconnaissance work and surface rock chip sampling have confirmed high-grade silver mineralisation extending nearly three kilometres from the initial discovery, located approximately 320 metres southwest of the historic Desert Antimony Mine (DAM).
Assay results have returned grades of up to 409 grams per tonne (g/t) silver, with 12 rock chip samples exceeding 30 g/t silver.
These results strongly reinforce the precious metal potential within the Mojave Project’s North Block.
In addition to silver, the sampling has revealed significant polymetallic mineralisation, with notable grades of base metals including copper, lead, and zinc.
The latest field results include assays of up to 4.2 per cent copper, 1.5 per cent lead, and 1.5 per cent zinc.
This multi-commodity presence enhances the overall prospectivity of the Mojave Project and supports the potential for large-scale mineralisation across the identified corridor.
According to Locksley, the interpreted mineralised zone extends approximately 2.4 kilometres west-northwest of the historic Hendricks Shaft and about 600 metres to the east-southeast.
This spatial trend supports the presence of a substantial hydrothermal system underlying the project area.
High-grade samples collected from outcropping veins and historic stockpiles exhibit gossanous textures and boxwork structures — geological indicators of weathered sulphide-rich polymetallic veins and potential fresh sulphide mineralisation at depth.
To date, a total of 398 rock chip samples have been collected across the Mojave Project’s North Block.
Approximately 260 of these samples were taken along the interpreted mineralised corridor between the Desert Antimony Mine and areas up to 5.6 kilometres to the southeast.
Among the additional highlights is a rock chip sample yielding 117 g/t silver and 3.1 per cent copper, collected near historic workings where visible copper carbonate mineralisation was observed.
Kerrie Matthews, Managing Director & CEO of Locksley Resources, said the identification of this mineralised trend represents a key development in the company’s ongoing exploration efforts.
“Defining a 3km mineralised trend with surface results of up to 409 g/t silver and 1.5 per cent copper is a highly encouraging outcome,” Matthews said.
“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.”
Looking ahead, Locksley plans to advance exploration of this newly defined silver and base metals corridor through a systematic program aimed at building a clearer understanding of its scale and potential.
The next phase of work will run in parallel with current activities at the Desert Antimony Mine and El Campo prospects.
Planned exploration includes detailed geological mapping, petrological and geochemical analyses, the evaluation of suitable geophysical surveys, and the delineation of high-priority, drill-ready targets along the mineralised trend.
The discovery marks a significant milestone for Locksley Resources as it continues to expand its U.S. critical minerals footprint and strengthen its diversified exploration portfolio in California.
