    EV Resources Accelerates Path to Production with Tecomatlán Plant Refurbishment Program

    EV Resources Limited (ASX: EVR) has commenced critical refurbishment works at its Tecomatlán Processing Plant in Mexico, marking a pivotal transition from explorer to near-term antimony producer. The EV Resources Tecomatlán Plant Refurbishment represents a strategic milestone as the company targets completion of the five-week grinding circuit upgrade by late April 2026, positioning itself as an early mover in the increasingly supply-constrained antimony market.

    The refurbishment focuses on bringing three previously uncommissioned ball mills into operation at a capital-efficient cost of approximately US$73,000. This approach leverages existing infrastructure to fast-track production capabilities while avoiding the typical multi-year development timelines associated with greenfield projects.

    Management Commentary:

    "The commencement of refurbishment at Tecomatlán marks a defining moment for EVR as we transition into production. We are not starting from scratch, we are unlocking an installed, unutilised processing asset at a fraction of typical capital cost." – Mike Brown, Managing Director & CEO

    Strategic positioning in critical minerals market

    EVR's timing appears strategically advantageous as antimony has been designated as a critical mineral by the US, EU, and Australia due to its essential role in energy storage, battery technology, defence, and high-tech applications. The company is establishing what it describes as a "centralised antimony processing hub" capable of treating both company-owned material and third-party ore.

    Key Strategic Advantages:

    • Capital Efficiency: Leveraging existing plant infrastructure reduces typical development costs
    • Speed to Market: Five-week refurbishment timeline versus years for greenfield development
    • Hub Model: Flexibility to process multiple ore sources reduces single-asset dependence
    • Location Benefits: Approximately 50km from high-grade Los Lirios project

    The Tecomatlán facility provides EVR with operational flexibility through its hub model, enabling the company to scale throughput in line with market demand. Furthermore, this approach maintains reduced reliance on any single ore source while maximising processing efficiency.

    Phased production strategy maximises early returns

    EVR has outlined a staged development approach designed to accelerate cash flow generation while building toward optimal recovery rates. The EV Resources Tecomatlán Plant Refurbishment incorporates this strategic phased methodology:

    Production Phase Recovery Rate Key Features
    Phase 1: Gravity Circuit ~90.8% Minimal permitting, early revenue
    Phase 2: Flotation Circuit Up to 99.2% Enhanced recovery, expanded capacity

    This phased approach enables early production and revenue generation while providing a clear pathway to increased recoveries and expanded capacity. In addition, the gravity circuit requires minimal additional permitting, allowing for faster implementation and immediate throughput.

    Refurbishment Program Details:

    Mechanical Works (Weeks 1-4):

    • Full overhaul and alignment of all three ball mills
    • Installation of upgraded discharge and safety systems
    • Delivery of full circuit redundancy for consistent throughput

    Electrical Upgrades (Week 5):

    • Installation of new 50 HP motors
    • Conversion to high-efficiency 440V configuration
    • Reduced infrastructure costs and improved operational efficiency

    Understanding antimony processing: the gravity circuit advantage

    What is gravity processing?

    Gravity separation uses the difference in specific gravity between antimony minerals and waste rock to achieve concentration. This method relies on physical properties rather than chemical processes, making it simpler to operate and requiring fewer permits.

    Why it matters for investors

    Gravity circuits offer several advantages for early-stage production that complement the EV Resources Tecomatlán Plant Refurbishment strategy:

    • Lower Operating Costs: Minimal chemical reagents required
    • Faster Permitting: Environmental approvals typically streamlined
    • Proven Technology: Well-established processes with predictable outcomes
    • Capital Efficiency: Lower upfront investment compared to flotation circuits

    The 90.8% recovery rate achieved through gravity processing represents a strong foundation for initial production. However, the flotation upgrade pathway provides clear visibility to enhanced recoveries of 99.2%.

    Ore supply strategy supports production readiness

    EVR is advancing multiple initiatives to ensure immediate production capability once commissioning is complete. For instance, the company is developing comprehensive supply chain partnerships to support the refurbishment program:

    Supply Chain Development:

    • Third-party ore supply agreements in progress
    • Ongoing metallurgical validation of feed sources
    • Strategic stockpiling initiatives ahead of commissioning
    • Integration with Los Lirios project development (50km proximity)

    This integrated approach differentiates EVR from typical early-stage operations by ensuring production readiness rather than entering extended ramp-up phases. Consequently, the company's strategy of securing multiple ore sources provides operational flexibility and reduces single-asset risk.

    Upcoming catalysts and timeline

    Immediate milestones (Q2 2026)

    The EV Resources Tecomatlán Plant Refurbishment timeline includes several key milestones:
