Locksley Resources (ASX:LKY) continues to advance multiple antimony and rare earth workstreams at the group’s Mojave Project in the US as part of the company’s mine-to-market strategy for US antimony supply.
The business has confirmed a drilling contractor for an upcoming exploration program planned for Q4 2025 at the El Campo target.
The program is designed to target the steeply dipping, structurally controlled mineralised horizon in five locations along the interpreted 860m-long northwest-southeast striking El Campo lode. This lode hosts elevated rare earths, as delineated from rock chip sampling conducted in 2023.
Locksley, which has a market capitalisation of $136.32 million, is also conducting a systematic sampling program at the Desert Antimony Mine (DAM), which will begin in the near-term. The program is designed to further evaluate grade continuity and confirm historical production records.
Further activities will be undertaken including field sampling and geophysics, as well as stream sediment and rock chip sampling.

A comprehensive light-detection and ranging (LiDAR) survey of underground adits and stopes has recently been completed at DAM, which provides data to inform program drilling design and future mine planning.
The survey will expand Locksley’s knowledge of historical antimony production. It will also provide a 3D wireframe model of the historical underground mine, which will assist with future drill targeting aiming to delineate unmined high-grade antimony mineralisation along strike from the historical stopes.
Locksley notes the dataset will enable the contractors to accurately integrate and geospatially align all underground scans, ensuring a precise 3D model of the DAM site.
CEO Kerrie Matthews says with the plan of operations approved pending bond finalisation, the company is beginning activities to prepare for an initial drilling program at the El Campo target.
“The team and I are extremely focused on our fast-track mine-to-market strategy and it positions Locksley to deliver near-term US antimony supply into critical defense and energy supply chains,” Matthews says.
The El Campo prospect and DAM sits within the Mojave Project in California, US.
Locksley Resources is a mineral explorer focused on critical minerals. The company is actively advancing exploration across its two assets named Mojave and Tottenham.
