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:LYRF) announced on October 20, 2025 that it produced a 100% American-made antimony ingot, sourcing ore from its Mojave Desert mine and refining it in the U.S. by Hazen Research.
The company calls the result a proof-of-concept for a full U.S. mine-to-metal supply chain and says it will focus on scaling the process commercially while working with partners and Washington DC advisors to advance permitting and funding.
Locksley Resources (OTCQX:LKYRF) reported that structural mapping at its Mojave Project expanded the Desert Antimony Mine (DAM) target horizon by 400% (sixfold), identifying a new parallel structural target and enlarging the potential mineralized corridor. Mapping was completed late in Q3 2025 and a third-phase structural program is expected to start next month.
Additional findings include regional lamprophyre dykes suggesting further critical-mineral potential, and high-grade silver assays up to 216 g/t Ag at the Hendricks Prospect with anomalous Zn, Pb and Cu. The company highlighted strategic alignment with U.S. onshoring policies and a collaboration with Rice University on DeepSolv™ for antimony processing.
Locksley Resources (OTCQB: LKYRF) reported initial metallurgical test work on surface samples from its Desert Antimony Mine in California produced a 68.1% antimony (Sb) flotation concentrate from first-pass rougher/regrind/cleaner tests. The company said this grade is ~95% of the technical maximum stibnite grade of 71.68% and comfortably exceeds a cited marketable threshold of 55% Sb. Locksley plans to collect a bulk underground sample for further testwork and ingot production and highlighted a collaboration with Rice University to develop DeepSolv™ for domestic antimony processing.
Locksley Resources (OTCQB: LKYRF) has appointed two industry veterans to key executive positions to accelerate its US antimony production strategy. Kerrie Matthews joins as CEO, bringing over 20 years of experience in major resource projects, including BHP's $3.8 billion South Flank Project and Iluka's $1.8 billion Eneabba Rare Earths Refinery.
Danny George has been named COO, bringing extensive global experience in project execution across mining, energy, and infrastructure sectors. The appointments aim to advance the Desert Antimony Mine in Mojave and establish large-scale commercial antimony processing capacity in the US. Additionally, Technical Director Julian Woodcook has resigned but will continue as a technical consultant.
Locksley Resources (OTCQB: LKYRF) has reported promising initial metallurgical test results from its Desert Antimony Mine (DAM) Prospect at the Mojave Project. The tests demonstrated antimony grades ranging from 27.5% to 39.1% with impressive recovery rates between 82.9% and 85.9% across six samples.
The results validate the project's potential to establish a domestic mine-to-market antimony supply chain, aligning with U.S. government priorities for critical mineral supply security. The company has partnered with Rice University to utilize their Deep Solv™ methodology for antimony extraction, advancing Locksley's U.S. Critical Minerals and Energy Resilience Strategy.
Locksley Resources (OTCQB: LKYRF) has announced a significant expansion of its exploration program in California's Mojave Desert following the addition of 249 new claims. The company's total landholding now encompasses 491 claims covering over 40 square kilometers of critical minerals-rich territory adjacent to MP Materials, North America's only active rare earths producer.
Recent geological mapping has revealed a substantial historical shaft estimated at over 15 meters deep. The company is currently evaluating the historical mining activities and commodity composition. Additionally, Locksley has formed a strategic collaboration with Rice University to develop DeepSolv™, aimed at domestic processing of North American antimony.
Locksley Resources (OTCQB: LKYRF) has significantly expanded its presence in California's Mojave Critical Minerals Corridor by staking 249 additional claims, bringing its total to 491 claims. The new claims are strategically positioned adjacent to MP Materials' Mountain Pass Rare Earth Mine, the only rare earths producing mine in the United States.
The expansion includes southeast claims encompassing favorable gneissic geology and northern claims located 3km from Dateline Resources Colosseum Gold Project. The company aims to explore antimony, rare earth elements (REEs), and polymetallic prospects. This strategic positioning enhances Locksley's potential for exploration discovery and downstream processing partnerships, aligning with U.S. government priorities for supply chain resilience.
Locksley Resources (OTCQB: LKYRF) has partnered with GreenMet, a Washington DC-based strategic advisory group, to advance its Mojave Critical Minerals Project in California. The partnership aims to position the project within key U.S. Government initiatives under the Defense Production Act, Inflation Reduction Act, and Department of Energy programs.
GreenMet's team includes Drew Horn, a former top US official and critical minerals strategy expert, Mark Green, former senior advisor to U.S. government agencies, and Retired General David Barrett. The partnership comes as the U.S. Department of Energy plans to issue $1 billion in funding opportunities for critical minerals and materials supply chains.
Locksley Resources (OTCQB: LKYRF) has entered into a strategic Research & Development Agreement with Rice University to develop domestic processing capabilities for U.S.-sourced antimony. The collaboration, centered around Locksley's Mojave Project, aims to address the critical supply chain gap in U.S. antimony processing.
The partnership involves two main initiatives: 1) Development of green hydrometallurgical extraction processes for antimony from mining feedstocks, and 2) Research on antimony-based materials for energy storage applications. This collaboration represents Locksley's implementation of its U.S. Critical Minerals and Energy Resilience Strategy, targeting both defense industry needs and next-generation energy storage systems.
Locksley Resources (OTCQB:LKYRF) announced plans to expand its geological and structural mapping program within the North Block of the Mojave Project in California. The company will focus on four priority areas, with two targeting rare earth elements (REE) potential and two focusing on antimony mineralization extensions from the Desert Antimony Prospect.
The program builds on the company's established REE potential at El Campo, which has shown high-grade rock chip results of up to 12.1% TREO and Nd/Pr up to 3.19%. The North Block's strategic location adjacent to MP Materials' Mountain Pass Mine, the only operating rare earths mine in the U.S., positions Locksley to potentially expand its critical minerals footprint across the underexplored 20 sq km area.
