EV Resources Ltd (ASX:EVR) Secures First Five-Year Binding Ore Supply Agreement, Advancing Tecomatlan Towards Proof-of-Concept Production

Perth, Aug 6, 2026 AEST (ABN Newswire) - EV Resources Limited (ASX:EVR) (R1EA:FRA) (EVRSF:OTCMKTS) announced another significant step towards its planned Proof-of-Concept antimony processing campaign at Tecomatlan, with its Mexican subsidiary Stibcorp S.A. de C.V. ("Stibcorp") executing EVR's first binding five-year Ore Supply Agreement with Lucero Grupo Minero de Puebla S.A. de C.V. ("Chinantla").

The Agreement brings together several key elements of EVR's Tecomatlan strategy. Chinantla is located approximately 8km from the plant, its ore has already been extensively tested through EVR's metallurgical program, and flotation testwork achieved 81.1% antimony recovery and produced a 42.4% Sb concentrate. EVR is also progressing the separate acquisition of an initial 200-tonne high-grade Chinantla stockpile intended as feed for the Company's Proof-of-Concept processing campaign.

Highlights

- First Binding Feedstock Agreement: EVR has converted the Chinantla MOU into its first binding five-year Ore Supply Agreement, establishing the commercial framework for ongoing deliveries of antimony ore to the Tecomatlan Processing Plant.

- High-Grade Ore Already Validated Through Tecomatlan Flowsheet: Chinantla ore has been extensively tested through EVR's metallurgical program, with flotation testwork achieving 81.1% antimony recovery and producing a 42.4% Sb concentrate.

- Only ~8km from Tecomatlan: Chinantla provides EVR with a nearby source of high-grade antimony ore with demonstrated metallurgical performance, significantly reducing haulage distance and supporting efficient feed delivery into the Company's Proof-of-Concept and subsequent processing campaigns.

- Critical Proof-of-Concept Feedstock Pathway: EVR continues to progress the separate acquisition of an initial 200-tonne high-grade Chinantla stockpile, intended to provide feed for the Tecomatlan Proof-of-Concept processing campaign.

- Plant + Ore + Metallurgy + Commercial Framework: With the Tecomatlan flotation circuit commissioned, Chinantla ore successfully tested and the first long-term commercial supply framework now executed, EVR has materially advanced the key components required for its planned Proof-of-Concept processing campaign.

- Regional Supply Network Being Built: EVR's existing feedstock MOUs contemplate volumes representing more than 50% of Tecomatlan's nameplate capacity. Chinantla is the first of these arrangements converted into a binding long-term commercial relationship and provides a commercial framework for progressing additional supply relationships.

- Benchmark-Linked Commercial Terms: Ore pricing is determined by reference to the international antimony price, payable antimony grade and agreed commercial adjustments, aligning feedstock purchasing with prevailing antimony market conditions.

- Los Lirios Advancing in Parallel: EVR continues to progress work towards a future proprietary source of antimony supply at (70% owned) Los Lirios, alongside the Company's broader third-party regional supply strategy.

With the Tecomatlan flotation circuit commissioned, the integrated processing flowsheet established, suitable third-party ore metallurgically tested and the first long-term commercial supply framework now executed, EVR continues to systematically bring together the plant, feedstock and commercial arrangements required to demonstrate its regional antimony processing model.

The Agreement converts the non-binding Memorandum of Understanding announced on 14 May 2026 into a binding commercial framework with a five-year initial term and automatic renewals for successive one-year periods. It is the first of EVR's regional feedstock MOUs to be converted into a binding agreement under the Company's hub processing strategy.

EVR's broader feedstock MOUs contemplate volumes representing more than 50% of Tecomatlan's nameplate capacity. The Chinantla Agreement therefore represents an important first conversion of EVR's regional feedstock pipeline from non-binding arrangements into documented commercial relationships ahead of the planned Proof-of-Concept campaign.

EV Resources Executive Chairman, Shane Menere commented:

"This is an important milestone because we are progressively bringing together every component required for the Tecomatlan Proof-of-Concept campaign: the plant, the processing flowsheet, tested high-grade ore and now our first binding long-term commercial supply relationship.

Chinantla is particularly important to us. It is approximately eight kilometres from Tecomatlan, we have already extensively tested its ore, and flotation testwork achieved those impressive recoveries. We are also progressing the acquisition of the initial 200-tonne high-grade stockpile intended for our Proof-of-Concept campaign.

Our strategy is to establish Tecomatlan as a regional processing hub supplied by multiple nearby antimony producers. Converting Chinantla from an MOU into a five-year binding commercial relationship is another important step in moving that model from concept into execution.

Importantly, EVR is funded through the Proof-of-Concept phase to demonstrate our capability to produce a marketable antimony concentrate. Beyond that milestone, our objective is to work with a select strategic and offtake partner that shares our ambition to build a secure and scalable North American antimony supply chain.

We see Tecomatlan as more than a standalone processing plant. Our objective is to build an integrated antimony value chain, combining regional ore supply and processing in Mexico with a pathway into the US market, complemented over time by our 100%-owned antimony prospects in Nevada.

We believe that creates a compelling platform for groups seeking secure, strategically located antimony supply into North America. We are building the platform, demonstrating the processing capability and establishing the supply network. We are currently in, and open to, new discussions with the right strategic partners who can help us accelerate the next stage."

Benchmark-Linked Pricing Supports the Tecomatlan Processing Model

Tecomatlan's processing model is designed around the value differential between delivered ore and the antimony concentrate produced through beneficiation.

Under the Agreement, pricing for individual ore purchases is established through Purchase Confirmations and determined by reference to the applicable international antimony benchmark, final payable antimony grade, treatment, refining and transportation charges, together with any agreed adjustments for moisture, impurities or penalty elements.

This structure provides EVR with a transparent commercial framework under which the price paid for ore reflects both prevailing antimony market conditions and the contained payable antimony determined through the agreed sampling and assay procedures.

Chinantla Ore Validated Through Metallurgical Testwork

Chinantla ore has been the principal third-party feed source used in EVR's metallurgical program. Flotation testwork returned antimony recovery of 81.1% and produced a concentrate grading of 42.4% Sb, compared with 29.25% Sb recovery and a 20.54% Sb concentrate using gravity concentration alone. These results provide EVR with important metallurgical validation of Chinantla ore ahead of the planned Proof-of-Concept campaign and supported the Company's decision to integrate gravity and flotation into the Tecomatlan processing flowsheet.

EVR continues to progress the acquisition of an initial 200-tonne parcel of high-grade stockpiled Chinantla ore. That parcel is intended to provide feed for the Proof-of-Concept processing campaign. The acquisition of the stockpile is a separate commercial arrangement to this Agreement.

Regional Hub Processing Strategy Moves from Concept to Execution

Tecomatlan is being developed as a regional processing hub for antimony miners across Puebla, Oaxaca and Guerrero, many of whom have limited access to nearby processing capacity, with alternative facilities located up to approximately 1,200km away.

EVR's strategy is to aggregate suitable antimony ore from multiple regional producers and process that material through the centrally located Tecomatlan facility. This approach provides regional miners with a potential local route to market while allowing EVR to progressively build a diversified feedstock network around existing processing infrastructure.

Ore volumes contemplated under EVR's existing non-binding feedstock MOUs represent more than 50% of Tecomatlan's nameplate capacity.

Chinantla is the first of these arrangements to be converted into a binding long-term commercial framework. Importantly, Chinantla ore has already been extensively tested through EVR's metallurgical program, the operation is located approximately 8km from Tecomatlan, and the Company is separately progressing acquisition of the initial 200-tonne high-grade stockpile intended for the Proof-of-Concept campaign.

EVR intends to continue progressing its remaining regional feedstock relationships towards binding commercial arrangements as the Company advances Tecomatlan through Proof-of-Concept and towards its broader processing objectives.

Tecomatlan Positioned at the Centre of a Regional Antimony Supply Network

Antimony producers across Puebla, Oaxaca and Guerrero face alternative processing capacity located up to 1,200km away. Haulage over that distance absorbs a substantial share of the value of the ore, which constrains what smaller regional operations can economically mine and sell. Tecomatlan is designed to give those producers a local route to market.

The approximately 8km distance between Chinantla and Tecomatlan demonstrates the potential advantage of this regional model. Shorter haulage distances can reduce transport costs and delivery cycle times while potentially bringing regional ore sources within economic reach of the Tecomatlan processing hub.

Antimony is designated a critical mineral by the United States, European Union and Australian governments, reflecting its use in defence applications, energy storage, flame retardants and semiconductor manufacturing. Chinese export controls introduced in 2024 have tightened supply available to Western markets and supported elevated antimony prices. Concentrate produced at Tecomatlan is positioned for buyers seeking supply outside Chinese controlled channels.

Proof-of-Concept Strategy Continues to Advance

EVR's immediate operational strategy is centred on demonstrating the Tecomatlan processing flowsheet using suitable regional antimony ore through a Proof-of-Concept processing campaign.

The Company has progressively advanced the key components required for that campaign, including commissioning of major processing equipment, metallurgical testwork on regional feedstocks, development of the integrated gravity and flotation flowsheet, progression of the initial 200-tonne Chinantla stockpile acquisition and now execution of the first binding long-term feedstock agreement.

The planned Proof-of-Concept campaign is intended to demonstrate the processing of regional antimony ore through Tecomatlan and provide operational and commercial information to support the Company's subsequent development strategy.

In parallel, EVR continues to develop its broader regional ore supply network and advance Los Lirios towards a maiden JORC Mineral Resource as a potential future proprietary source of antimony feed.

Next Steps

EVR's immediate priorities at Tecomatlan are:

- Complete the acquisition of the initial 200-tonne high-grade Chinantla stockpile intended for the Proof-of-Concept campaign;

- Complete remaining plant integration and commissioning activities required for the planned Proof-of-Concept campaign;

- Commence the Proof-of-Concept campaign processing bulk sample material through the Tecomatlan flowsheet;

- Continue converting additional regional feedstock MOUs into binding commercial supply arrangements;

- Continue developing the regional antimony feedstock network around Tecomatlan; and

- Progress the maiden JORC Mineral Resource at Los Lirios in parallel as a potential future proprietary feed source.
