EV Resources Accelerates Los Lirios Antimony Project: Multiple High-Grade Targets Identified
EV Resources Limited (ASX: EVR) has announced significant progress at its flagship Los Lirios Antimony Project in Mexico's Oaxaca State. The company has completed over 4.4 kilometres of new access roads, mapped more than 5 kilometres of mineralised structures, and designed 30 trenches with approximately 250 channel samples planned as it advances toward resource definition and drilling.
"The Los Lirios exploration program is advancing rapidly, with multiple workstreams progressing in parallel," commented EVR Chairman Shane Menere. "The completion of access roads, trenching, and systematic sampling is already revealing the scale of mineralisation across the concessions. With early drill targets identified, metallurgical testing underway, and strong community engagement, Los Lirios is shaping into a significant antimony development opportunity."
Extensive Mineralisation Uncovered Across Multiple Zones
The company's exploration program has made substantial progress in defining the scale of antimony mineralisation at Los Lirios. Initial mapping at Lirios 2 has traced a mineralised structure over 2 kilometres long, with an impressive outcrop area of 400m x 30m. This work has already led to the identification of five high-priority drill targets.
Regional geological mapping indicates the mineralised trend may extend for at least 5 kilometres across the Los Lirios concessions, suggesting significant resource potential. Previous sampling of stockpiled material from Los Lirios 3 returned exceptional high-grade antimony assays of 29.2%, 20.4%, and 18.1%, highlighting the project's prospectivity.
| Exploration Progress | Details |
|---|---|
| Access Roads | 4.4 km completed across Lirios 1, 2 & 3 |
| Mapped Structures | >5 km total strike length identified |
| Trenching Program | 30 trenches designed, ~250 samples planned |
| Previous High-Grade Samples | 29.2%, 20.4% & 18.1% antimony |
| Drill Targets | 5 high-priority targets identified |
Infrastructure Development Paves Way for Advanced Exploration
The completion of critical infrastructure has been a key achievement in the Los Lirios work programme. The company has successfully constructed over 4.4 kilometres of new access roads at Lirios 1, 2, and 3, providing direct entry to historic mining workings, including pits, shafts, and adits.
This infrastructure will enable efficient trenching operations and facilitate the establishment of drill pads for the upcoming advanced exploration programme. Road construction has been strategically planned to connect the main town road with key exploration areas, ensuring year-round accessibility to the project site.
This is a critical factor for maintaining momentum in the exploration and development timeline at the EV Resources Los Lirios project.
Metallurgical Testing Aims to Optimise Processing Options
EVR has initiated comprehensive metallurgical test work on representative samples from Lirios 1 and 3, led by senior metallurgist Abel Salazar. The programme includes:
- Gravity concentration trials
- Flotation testing
- Leaching evaluations
This work is assessing various flowsheet options for both metallic antimony precipitation and antimony trioxide concentrate production. Results will inform the processing strategy and support partnership discussions for future concentrate production.
Understanding Antimony: A Critical Mineral for Modern Applications
Antimony is classified as a critical mineral by many countries due to its essential applications and supply concerns. This metalloid element combines with other metals to form alloys with specific, valuable properties.
Why Antimony Matters to Investors:
Antimony has diverse applications across multiple high-growth industries:
- Energy Storage – Used in certain battery technologies, including liquid metal batteries and lead-acid batteries
- Defence Applications – Critical component in military equipment, ammunition, and infrared devices
- Flame Retardants – Antimony trioxide is widely used as a flame retardant in plastics, textiles, and electronics
- Electronics – Used in semiconductor manufacturing and microelectronics
With China controlling approximately 60% of global antimony production, new supply sources outside Chinese influence present significant strategic value. This makes the EV Resources Los Lirios project particularly appealing from both commercial and geopolitical perspectives.
Environmental Permitting and Community Relations
EVR has made substantial progress on the regulatory and social fronts. The company holds an approved Environmental Impact Study (MIA) for Lirios 1 and 3, while work is underway to extend the permit to include Lirios 2.
Furthermore, engagement has begun with seven local communities, including medical support initiatives. A comprehensive Social Management Strategy (SMS) is being developed to ensure sustainable relationships with local stakeholders.
These efforts demonstrate EVR's commitment to sustainable development and responsible mining practices. By proactively addressing environmental compliance and community relations, the company is mitigating potential future obstacles to project advancement.
Strategic Pathway to Value Creation
EVR's systematic approach at Los Lirios follows a clear progression toward establishing a significant antimony resource:
- Infrastructure Development – ✓ Completed access roads
- Geological Understanding – ✓ Mapping of mineralised structures
- Surface Sampling – In progress (trenching and channel sampling)
- Metallurgical Testing – In progress (gravity, flotation, leaching trials)
- Drill Target Generation – ✓ Five high-priority targets identified
- Maiden Drilling Program – Planned following assay results and modelling
- Resource Definition – Target outcome of current workstreams
The next phase will see the completion of trenching and delivery of initial channel sample assays, followed by preliminary metallurgical results and the preparation for a maiden drilling programme targeting the high-priority structures at Lirios 2 and 3.
Why Investors Should Watch EV Resources
The EV Resources Los Lirios project presents a compelling investment case for several reasons:
- Exposure to Critical Minerals – Antimony is designated as a critical mineral by the US, EU, and Australia, with supply constraints and growing demand
- High-Grade Potential – Initial samples showing exceptional grades (up to 29.2% antimony)
- Significant Scale – 5km mineralised trend identified with multiple target zones
- Clear Development Pathway – Systematic exploration approach moving toward resource definition
- Strategic Location – Mexico provides a stable mining jurisdiction outside Chinese antimony dominance
The company's focused approach to advancing Los Lirios positions it to potentially become a significant player in the antimony market, particularly as global demand increases for this critical mineral across defence, energy storage, and flame-retardant applications.
What Makes the Los Lirios Project Stand Out?
The EV Resources Los Lirios project combines several advantageous elements that are rarely found together in mining developments. The high-grade nature of the antimony mineralisation, coupled with the extensive strike length and multiple target zones, provides multiple pathways to success.
Additionally, the established infrastructure and regulatory progress already achieved significantly de-risk the project compared to many early-stage exploration ventures.
"EV Resources has positioned itself to capture value in the antimony market through its systematic development of the Los Lirios project. With significant exploration progress, high-grade samples, and a clear pathway to resource definition, EVR offers investors exposure to a critical mineral with growing strategic importance in a time of increasing geopolitical supply concerns."
