EV Resources has begun refurbishing its Tecomatlán Processing Plant in Mexico, marking a pivotal shift from exploration to near-term antimony production amid tightening global supply. The company aims to leverage this low-cost, staged approach to secure a first mover advantage in the critical minerals market.
- Grinding circuit refurbishment underway with three ball mills
- Low-capital US$73,000 restart targets late April commissioning
- Tecomatlán positioned as North America’s central antimony hub
- Staged production strategy: gravity circuit followed by flotation
- Ore supply agreements and stockpiling advancing for immediate throughput
From Exploration to Production
EV Resources Limited (ASX:EVR) has taken a decisive step towards becoming a near-term antimony producer with the commencement of refurbishment works at its Tecomatlán Processing Plant in Puebla, Mexico. This move signals a clear transition from exploration to operational execution, positioning EVR to capitalise on a critical mineral market facing increasing supply constraints globally.
The refurbishment focuses on the plant’s grinding circuit, the operational heart comprising three ball mills that were installed but never commissioned. By overhauling these mills and upgrading electrical systems, EVR aims to unlock rapid production capacity at a fraction of typical capital costs; approximately US$73,000; targeting commissioning completion by late April 2026.
Strategic Hub for North American Antimony
Tecomatlán is being developed as a centralised processing hub capable of treating both EVR’s own ore and third-party supplies. Located just 50 kilometres from the high-grade Los Lirios Antimony Project, this facility offers a streamlined pathway from exploration to production. The hub model reduces reliance on any single ore source and provides flexibility to scale operations in response to market demand, a critical advantage given the tightening global antimony supply.
Antimony is a vital mineral for defence, energy storage, and advanced technologies, and EVR’s early mover strategy seeks to capture market share ahead of competitors. The company’s approach combines existing infrastructure with a staged production model to accelerate revenue generation while managing risk.
Phased Production and Supply Readiness
EVR’s staged production plan begins with a gravity circuit designed to achieve approximately 90.8% recovery with minimal permitting hurdles. This will be followed by a flotation circuit aiming for recoveries up to 99.2%, enhancing output and operational scale. Parallel to plant refurbishment, EVR is advancing ore supply agreements and stockpiling initiatives to ensure immediate throughput once commissioning is complete.
By integrating these elements, EVR is not only accelerating its pathway to first cash flow but also mitigating the typical ramp-up risks associated with early-stage mining operations. This disciplined approach underlines the company’s commitment to operational delivery and market engagement in the months ahead.
Looking Ahead
With refurbishment progressing on an accelerated five-week schedule, EVR is poised to deliver ongoing updates on commissioning milestones, production readiness, and drilling results from Los Lirios. The company’s leadership emphasises the strategic importance of unlocking an installed but previously unused processing asset, enabling a capital-efficient entry into a critical mineral market where secure supply is increasingly vital.
EVR’s next steps include finalising ore supply contracts, completing plant-wide commissioning, and advancing strategic partnerships and offtake agreements. These developments will be closely watched by investors and industry observers keen to see how EVR’s early mover advantage unfolds in the evolving antimony landscape.
Bottom Line?
EV Resources’ low-cost, rapid refurbishment strategy could redefine North American antimony supply; next milestones will reveal if the promise translates into production.
Questions in the middle?
- Will EVR secure sufficient third-party ore supply to sustain immediate throughput post-commissioning?
- How will global antimony price fluctuations impact EVR’s staged production economics?
- What are the potential operational risks during the transition from refurbishment to full-scale production?
