Antimony Resources has begun trading under the ANT code as its Tecomatlán processing plant in Mexico moves closer to its first processing campaign. About 200 tonnes of mineralised material has been prepared, but assay results and commissioning outcomes are still to come.
- Trading begins under ANT after name change from EV Resources
- Approximately 200 tonnes of mineralised material crushed and stockpiled
- Flotation circuit about 90% complete
- Grinding infrastructure and Ball Mill No. 2 work continue
- Head-grade assays and commissioning results remain key tests
Tecomatlán Moves From Construction Towards Processing
Antimony Resources Limited (ASX:ANT), formerly EV Resources, has reached a more consequential milestone than its new ticker suggests: the Tecomatlán antimony processing plant in Puebla, Mexico, now has approximately 200 tonnes of prepared mineralised material ready for the next stage of process testing.
The crushing campaign is complete and representative samples have been sent to the laboratory to confirm the estimated head grade. That result will provide an important reference point before the company attempts to reconcile feed grades, recoveries and concentrate performance through its planned Proof-of-Concept campaign.
Grinding and Flotation Installation Nears Completion
Work remains on schedule, according to the company, with attention shifting to the grinding circuit and its connection to the conditioning and flotation sections. The cyclone box structure and conveyor to mill feed are approximately 70% complete, while installation of the mill discharge pump is about 80% complete.
Two 3 × 3 SRL slurry pumps and two cyclones have arrived at site, while rectification of the crown gear and pinion for Ball Mill No. 2 is under way. The flotation circuit is approximately 90% complete, with valve checks and blower installation still in progress ahead of dry commissioning and the eventual move to wet commissioning.
New ANT Identity Puts Antimony at the Centre
The company began trading on the ASX under ANT on 21 September, replacing EVR. Its listed options now trade as ANTO and ANTOA. The name change follows shareholder approval and the recently completed capital consolidation, and does not alter shareholder rights or the company’s operations.
Executive chairman Shane Menere said the new identity reflects a single focus on antimony, with the company positioning Tecomatlán as a processing hub for Mexican feed sources while advancing the Los Lirios project, the Chinantla antimony project and its Dollar and Milton assets in Nevada. Those ambitions remain prospective: the announcement does not report concentrate production, recovery rates, a firm commissioning date or an economic outcome.
Assays and Commissioning Provide the Next Test
Reagents for the planned campaign are already on site, and Antimony Resources intends to use a Niton XRF analyser for rapid operating guidance while sending representative feed, concentrate and tailings samples to ALS for independent laboratory analysis.
The next meaningful evidence will therefore come from the head-grade results, mechanical and electrical commissioning, and the plant’s ability to produce a marketable antimony concentrate from the prepared material. Until those results arrive, the 200-tonne stockpile and completion percentages demonstrate readiness for testing rather than proof of commercial production.
Bottom Line?
ANT has assembled the material and is approaching commissioning, but the investment case now turns on what the plant actually recovers and produces.
Questions in the middle?
- What head grade will the laboratory confirm for the approximately 200 tonnes of prepared material?
- Will dry and wet commissioning proceed on schedule once the grinding and flotation circuits are integrated?
- Can the Proof-of-Concept campaign demonstrate recoveries and concentrate quality sufficient to support future commercial supply or offtake discussions?
