Locksley Resources Accelerates Desert Antimony Development with Engineering Partner Selection
Locksley Resources (ASX: LKY) has taken a major step toward commercial antimony production by formally launching the Locksley Resources partner selection process for its Desert Antimony Mine scoping study. The company has issued expressions of interest (EOI) to tier-one U.S. engineering firms, marking a critical milestone in its strategy to establish an integrated domestic antimony supply chain.
The initiative comes at a time when the U.S. government is prioritising the rebuilding of domestic critical mineral processing capabilities to reduce dependence on foreign supply chains. Furthermore, with over $20 million in cash funding its 2026 work programmes, Locksley is well-positioned to capitalise on this strategic opportunity.

Strong Industry Response Validates Development Strategy
The EOI process has generated highly encouraging responses from leading engineering firms, who recognise both Locksley's structured development approach and the project's alignment with federal critical mineral priorities. Respondents have specifically acknowledged the company's disciplined technical de-risking methodology and pragmatic study execution framework.
Key selection criteria for engineering partners include:
- Demonstrated experience operating in San Bernardino County
- Regulatory engagement capabilities and permitting pathway expertise
- Local stakeholder management experience
- Technical capability aligned with antimony processing requirements
This regional experience requirement reflects Locksley's commitment to ensuring timely project delivery through partners who understand local regulatory environments and operational challenges.
Integrated Approach Accelerates Development Timeline
Locksley is implementing an innovative concurrent development strategy that integrates metallurgical optimisation with engineering design work. This approach allows both workstreams to advance simultaneously, maintaining development momentum whilst ensuring technically robust outcomes.
The integrated methodology includes:
- Ongoing metallurgical optimisation to refine processing flowsheets
- Recovery improvement initiatives and mass balance validation
- Real-time engineering design updates based on metallurgical findings
- Concurrent study progression to eliminate sequential delays
"Our ongoing metallurgical optimisation work will feed directly into the scoping study, allowing engineering design, economic evaluation and project planning to progress without delay," said Kerrie Matthews, Managing Director & CEO.
Understanding Scoping Studies: The Foundation of Mining Development
A scoping study represents the preliminary engineering and economic assessment phase of mine development. It provides investors with initial projections of project viability, capital requirements, and operational parameters before more detailed feasibility studies begin.
Why scoping studies matter to investors
Scoping studies serve as the first comprehensive economic assessment of project potential, establishing whether a mineral deposit warrants further investment. These studies typically estimate capital and operating costs within a range of ±40% to ±50% accuracy, providing sufficient detail for preliminary investment decisions.
The studies examine production forecasts and revenue projections based on current resource understanding and proposed mining methods. For instance, Locksley's Desert Antimony Mine evaluation will include processing capacity estimates, recovery rates, and annual production targets aligned with market demand projections.
Risk identification and mitigation strategies form a crucial component, addressing technical, environmental, and regulatory challenges that could impact project development. Consequently, the Locksley Resources partner selection process will establish baseline assumptions for subsequent detailed studies and financing decisions.
Most importantly, scoping studies provide the foundation for subsequent detailed studies including pre-feasibility and definitive feasibility assessments. They establish the technical and economic framework that guides all future development decisions.
Strategic Timeline Positions Company for 2026 Catalysts
Locksley has outlined a clear progression pathway with specific milestones designed to maintain development momentum throughout 2026:
| Phase | Timeline | Key Deliverables |
|---|---|---|
| EOI Evaluation | Q4 2025 | Partner technical assessment and selection |
| RFP Issuance | Mid-Q1 2026 | Formal proposal requests for PFS and site investigation |
| Contract Awards | End Q1 2026 | Processing scope contracts finalised |
| Mine Engineering | Q2 2026+ | Engineering packages aligned with exploration results |
This structured approach ensures continuous project advancement whilst allowing flexibility to incorporate new exploration data and metallurgical improvements as they become available.
The company's separable work package strategy enables different technical disciplines to progress independently where appropriate. In addition, this approach reduces overall timeline risk whilst maintaining quality control standards.
Investment Thesis: Positioning for U.S. Critical Mineral Independence
Locksley's Desert Antimony Mine development strategy aligns directly with escalating U.S. government initiatives to rebuild domestic critical mineral supply chains. The company's integrated mine-to-market approach addresses a significant strategic vulnerability in American industrial capabilities.
Key investment drivers include
The United States currently has zero domestic antimony production despite high industrial demand across multiple sectors. Critical defence applications in semiconductors and metal alloys create consistent demand that must currently be met through imports.
Geopolitical supply chain risks from Chinese market dominance present ongoing vulnerability for American manufacturers. China controls approximately 85% of global antimony production, creating strategic dependence that federal policy makers are actively working to address.
Furthermore, federal policy support for domestic critical mineral development provides a supportive regulatory environment through initiatives including the Defence Production Act and critical mineral designation programmes.
The Desert Antimony Mine represents one of the highest-grade known antimony occurrences in the United States, having operated historically until 1937. However, with modern mining and processing technologies, the asset offers significant potential for efficient, profitable production.
Locksley maintains a strong cash position enabling accelerated development programmes without immediate dilution concerns. Consequently, this allows management to focus on value-creating activities throughout the critical 2026 development phase.
