The Americas

Los Lirios Antimony Project (EVR: 70%)

The Los Lirios Project (EVR 70%) is the cornerstone of our plan to fast-track North American antimony supply. Located in the state of Oaxaca, Mexico, this high-grade asset offers a rare combination of geological potential and immediate path-to-production infrastructure.

Unlike conventional mining projects that face lengthy development timelines, Los Lirios is an active opportunity. Combining this high-grade resource with our nearby Tecomatlán Processing Plant, EVR is executing a vertically integrated strategy designed for near-term production and long-term scalability.

Project Snapshot

Ownership: 70% Interest (Joint Venture)

Location: Zapotitlán Lagunas, NW Oaxaca State, Mexico

Land Package: 1,552 hectares across three licenses (El Lirio Del Los Valles 1, 2 and 3 Fraccion 1)

Primary Commodity: Antimony (Sb)

The Opportunity

Global antimony markets are in a structural deficit, with few non-Asian sources ready to come online. EV Resources identified Los Lirios not just for its geological grade, but for its ability to quickly emerge as a new low-cost supplier.

The project sits in a jurisdiction with a rich mining history and skilled local labour, ideal for the ‘small-scale to large-scale’ ramp-up strategy we are employing.

2026 Exploration Program

Maiden Drilling Campaign

Following a successful site preparation campaign in late 2025, EVR has finalised logistics for a fully funded Phase 1 diamond drill program (1,500 – 2,000m) scheduled to begin early January 2026.

The program marks a pivotal transition from explorer to potential resource developer.

Target Zone: Test approximately 900m of strike within the broader 4km mapped system.

Primary Objectives

Test immediate extension below the high-grade Lirios 1 and Lirios 2 historical artisanal pits.
Validate the Lirios Fault Zone (LFZ) structural model at depth.
Define priority zones to underpin a Maiden JORC Resource targeted for Q3 2026.

Geology & Mineralisation

Los Lirios has historically demonstrated exception high-grade mineralisation. The project is characterised by structurally controlled antimony deposits typical of the Oaxaca region, where mineralisation is often concentrated in high-grade veins and breccia zones rather than low-grade disseminated deposits.

Detailed field mapping and structural measurements have allowed EVR to refine its geological model, identifying two distinct mineralisation styles that will be tested in drilling.

Lirios Fault Zone (LFZ)

Principal fluid conduit and host structure for antimony mineralisation at Los Lirios. Mineralisation associated with the LFZ occurs as quartz-stibnite infill, veining, and strong silicification, which parallels the anticline axis of a weakly folded limestone sequences.

Crackle brecciation and silicification along the fold axis indicates folding pre-dated faulting, providing a mechanical weakness for the LFZ and access for ascending hydrothermal fluids. Pit mapping demonstrates additional mineralisation associated with NW-SE striking cross-faults.

These are interpreted as en-echelon structures related to the broader strike-slip stress regime that formed the LFZ.

Carbonate-replacement bodies (CRD)

Sub-horizontal CRDs located within limestone units directly beneath a ductile gypsum layer. The gypsum appears to have acted as a barrier, acting as a cap seal mechanism, forcing hydrothermal fluids to spread laterally into selective limestone units, and replacing carbonate material.

This has produced 2–5 metre-thick stratabound (Manto) replacement zones observed in multiple pits.
