EV Resources (ASX:EVR) Clears Key Permit Hurdle for Mexico Antimony Project

Highlights

• EVR has secured the Change of Use of Soil permit for its Tecomatlán Processing Plant in Puebla, Mexico.
• The permit allows the company to submit the Informe Preventivo, the final environmental reporting requirement before Phase 1 operations.
• EVR has lodged an application for grid interconnection with Mexico’s Comisión Federal de Electricidad (CFE).
• Connection to the national electricity grid is expected to lower processing costs and reduce exposure to diesel price fluctuations.

EV Resources Limited (ASX:EVR) has achieved a major regulatory milestone for its Tecomatlán Processing Plant in Puebla, Mexico, advancing the company’s plans for near-term antimony production. The Change of Use of Soil permit now enables EVR to move ahead with the final environmental reporting process required before the commencement of Phase 1 operations. At the same time, the company has submitted its application for grid interconnection with Mexico’s national electricity authority.

EVR Receives Key Land-Use Permit for Tecomatlán Plant

The owner of the Tecomatlán Processing Plant has received the Cambio de Uso de Suelo (Change of Use of Soil) permit, a key regulatory approval under Mexico’s land-use framework.

Following receipt of the permit, the company is now eligible to submit its Informe Preventivo (Preventive Report), described by the company as the final administrative requirement before operating the Phase 1 gravity circuit and to establish connection with the national grid.

The company noted that its Phase 1 reagent-free process flow sheet, including dry-stacked tailings design do not require additional environmental permits before construction activities begin. EVR’s environmental consultant is currently finalising the Preventive Report for submission to Mexican authorities.

Grid Connection Application Submitted to CFE

An application for grid interconnection has been formally filed with Mexico’s national electricity authority, the Comisión Federal de Electricidad (CFE).

According to the company, the land-use permit was mandatory before an industrial user could apply for a new electricity connection. CFE has confirmed that sufficient capacity exists at the proposed interconnection point to support the plant’s projected power requirements.

The required infrastructure is expected to include a step-down transformer, installation on an existing power pole, and less than 150 metres of cabling connecting the facility to the plant’s transformer and switchboard.

Reduced Reliance on Diesel Generation

The transition from diesel-powered generation to the national electricity grid is expected to reduce the plant’s exposure to fluctuations in domestic diesel pricing.

EVR stated that access to the national grid is likely to lower unit processing costs.

Next Steps for Phase 1 Development

With dry commissioning of the grinding circuit already completed, the company’s near-term priorities include the submission of the Informe Preventivo, progression of engineering design reviews, advancing interconnection studies for physical grid connection, and delivery of Falcon gravity concentrators to the site.

EVR is also progressing discussions with regional miners regarding additional third-party feedstock and stockpiling material, while continuing metallurgical and characterisation studies. In parallel, the company is advancing negotiations for offtake agreements ahead of first concentrate sales during commissioning.

The latest permit approval and grid connection application represent important developments for EVR’s Tecomatlán antimony project in Mexico. With the final environmental filing now imminent and infrastructure preparations progressing, the company is continuing work toward the commencement of Phase 1 operations.
