Locksley Resources Ltd. reports developments tied to its U.S. critical minerals portfolio, led by the Mojave Project in California. Recurring updates cover rare earth element and antimony exploration, including work at the Desert Antimony Mine and the El Campo REE prospect, as well as surface sampling, underground mapping, diamond drilling, and mineralized silver-copper targets within the project area.
Company news also follows Locksley’s mine-to-market antimony strategy and research collaborations with U.S. institutions. These updates address metallurgical testwork, antimony concentrate and antimony trioxide production pathways, rare earth processing, separation and metallization research, and potential downstream materials applications.
Locksley Resources (OTCQX: LKYLY) reported high-grade antimony results from a batch sampling program at the DAM deposit, Mojave Project, California on Feb 3, 2026.
Three batches (total 287kg) returned weighted averages of 25.7% Sb, 21.3% Sb, and 11.4% Sb. Prior late-2025 work included a 325kg sample and a 68.1% Sb premium concentrate. Locksley says it is pursuing a mine-to-market strategy with downstream partnerships to rebuild U.S. antimony supply chains.
Locksley Resources (OTCQX:LKYRF / OTC:LKYLY / ASX:LKY) reported confirmation of a continuous, high-grade silver corridor at its Mojave Project in California after surface reconnaissance and rock-chip sampling across the North Block. The company said the mineralized trend now measures 3 km and returned surface assays up to 409 g/t silver and 1.5% copper, extending known high-grade mineralization beyond the initial discovery. Management described the result as an advancement of its exploration strategy and complementary to its antimony and critical-minerals focus, with a staged exploration program planned to further evaluate the opportunity.
Locksley (OTCQX: LKYRF) is advancing a US-focused mine-to-market antimony and rare earths strategy centered on the Desert Antimony Mine (Mojave Project, CA).
Key announced items include a A$17 million heavily oversubscribed placement, initiation of an engineering scoping pilot plant partner selection, a completed bulk sample returning head grades of 7.6–9.6% Sb and flotation work producing a 68.1% Sb premium concentrate, and an exploration target of 19,400–67,000 tons of antimony metal (conceptual).
Locksley also disclosed US research partnerships (Columbia, Rice), advisory board appointment of a US defense materials executive, and expressions of interest from US engineering contractors to support development.
Locksley Resources (OTCQX: LKYRF) announced on December 11, 2025 that it has commenced an engineering partner selection process for a scoping pilot plant design at the Desert Antimony Mine following direct engagement with Tier 1 U.S. service providers.
The company said completion of a recent capital raise is allowing it to fast-track 2026 development initiatives, and that ongoing metallurgical optimization will feed the scoping study to support engineering design, economic evaluation and project planning. Locksley is advancing a mine-to-market strategy at its Mojave Project in California to help reestablish a domestic U.S. antimony supply chain.
Locksley Resources (ASX: LKY; OTCQX: LKYRF) appointed Stacy Newstead as Strategic Advisor — Materials Strategy on Nov. 24, 2025.
Newstead brings 20+ years of U.S. government, defense and industrial materials experience, currently serving as Materials Strategy and Risk Manager at Lockheed Martin and previously holding senior roles at Huntington Ingalls, Textron Systems and Evolution Energy Minerals. Management says her experience will help engage U.S. partners and access federal programs supporting domestic critical mineral supply chains.
Locksley is advancing the Mojave Project in California targeting rare earths and antimony and pursuing a mine-to-market strategy with downstream technology partnerships.
Locksley Resources (ASX: LKY; OTCQX: LKYRF) announced a sponsored research agreement with Columbia University on Nov 17, 2025 to develop sustainable processing technologies for rare earth elements (REEs) and critical metals from ores in the Mountain Pass/Clark Mountain District, California.
The program, led by Professor Greeshma Gadikota, targets integrated characterization, recovery and separation of REEs and transition metals from carbonatite, monazite and silicate ores. Locksley says the collaboration complements its Rice University DeepSolv™ DES antimony work and supports its Mojave Project mine-to-market strategy to reestablish U.S. critical minerals supply chains.
Locksley Resources (OTCQX: LKYRF) provided a project update for its Desert Antimony Mine (DAM) prospect in the Mojave Project on Nov 13, 2025. Key technical steps completed include LiDAR-confirmed 236m of underground development across four levels, an exploration target of 19,400–67,000 tons of antimony metal (conceptual, JORC 2012), and bulk sampling that returned 7.6–7.8% Sb head grades with a sighter test producing a 68.1% Sb concentrate.
The company says it has initiated development planning, received U.S. engineering interest, has drilling approval for up to 16 holes (pending bond), and is coordinating permitting, financing (EXIM LOI referenced) and pilot plant work with timelines into Q4 2025–Q1 2026.
Locksley Resources (OTCQX: LKYRF) is advancing a U.S. mine-to-market plan at the Desert Antimony Mine (DAM) with workstreams aimed at pilot production in 2026. Key technical milestones include LiDAR mapping of ~236m of historical workings, a JORC 2012 Exploration Target of 19,400–67,700 tonnes of antimony metal, and a 325 kg bulk sample averaging 7.6–7.8% Sb that produced a 68.1% Sb concentrate in testwork. Locksley has signed an MoU with Hazen Research and a collaboration with Rice University on extraction technology, and is assessing underground access and permitting pathways.
Sector context: Permitting and export-policy shifts from China and large financings and revenue moves at U.S. peers underline market opportunity and near-term policy risk for antimony supply chains.
Locksley Resources (OTCQX: LKYRF) received a Letter of Interest from EXIM dated Nov 3, 2025 outlining intent to provide up to US$191 million in potential project financing for the Mojave Project in California.
The LOI supports due diligence and underwriting toward a formal financing package while the company advances upstream mine development, downstream modular refining with Rice University collaboration, and production of a 100% American made antimony ingot. EXIM programs cited prioritize critical minerals that reduce foreign supply dependence and support U.S. national security.
Locksley Resources (OTCQX: LKYRF / ASX: LKY) announced on October 21, 2025 the production of a 100% American-made antimony ingot sourced from its Mojave Desert Antimony Mine and refined by Hazen Research in Colorado. The milestone validates a US mine-to-metal supply chain independent of Chinese processing and supports US government critical-mineral objectives.
Key technical result: a 68.1% antimony first-pass concentrate (95% of technical maximum 71.68%), exceeding typical marketable thresholds. Locksley is advancing to pilot-scale production, permitting, offtake engagement, and funding discussions with advisors including GreenMet.
