Why is antimony a significant focus for EV Resources (ASX:EVR) right now?

Antimony is currently experiencing a strong pricing environment, making high-grade discoveries more economically attractive. As a critical mineral used in flame retardants, lead-acid batteries, and solar glass, establishing a stable supply from projects like Los Lirios aligns with the global push for resource security.

What were the standout drilling results from the Los Lirios announcement?

The first-pass technical validation program yielded a top intercept of 3.05m at 2.1% antimony from a depth of only 8.1m. These results exceeded the company’s internal expectations for a reconnaissance-style program.

How does the "shallow geometry" of this discovery benefit investors?

The fact that mineralisation starts less than 10 metres from the surface suggests the project is amenable to open-pit mining. For investors, this typically means lower stripping ratios (less waste rock to move) and reduced drilling costs.

What does "lateral continuity" mean for the EV Resources investment thesis?

Lateral continuity proves that the mineralised zones are connected over a wide area rather than being isolated pockets. This is a critical requirement for "bulk-tonnage" operations, which rely on large volumes of ore to be profitable.

What are the main "bull case" points for EV Resources (ASX:EVR) after this news?

The primary bull points include the high-grade nature of the intercepts (up to 2.1% antimony) and the very shallow depth, which simplifies potential extraction. Additionally, the discovery validates management's geological model, reducing exploration risk for the broader Los Lirios corridor.

EV Resources confirms extensive shallow antimony system

Q: What did EV Resources (ASX:EVR) discover at the Los Lirios project?

EV Resources confirmed a broad, shallow, and laterally extensive antimony-bearing carbonate replacement system (CRD) during its maiden diamond drilling campaign in Mexico.

EV Resources (ASX:EVR) announced a breakthrough at its Los Lirios Project.

Initial assays from the company’s maiden diamond drilling campaign have officially confirmed the existence of a broad, shallow, and laterally extensive antimony-bearing carbonate replacement system.

The discovery marks a pivotal moment for the project, establishing a mineralised footprint that may support large-scale, open-pit mining operations.

The first-pass technical validation programme saw four out of five initial holes at the Lirios 1 target intersect the mineralised horizon at depths of less than 10m.

These results exceeded internal expectations, with a standout intercept of 3.05m at 2.1% antimony from just 8.1m.

By proving that mineralisation extends well beyond historical workings, EV Resources has validated the system’s lateral continuity—a key requirement for bulk-tonnage development.

Managing Director Mike Brown described the results as a "highly encouraging outcome" that materially strengthens confidence in the corridor’s broader potential.

Brown noted that the combination of high grades and shallow geometry is particularly significant given the current strong pricing environment for antimony.

Such a configuration could lead to lower stripping ratios and reduced drilling costs in future phases.

Following the validation, the company is now preparing for a systematic Phase 2 drilling programme aimed at delineating the full scale and resource potential of the Los Lirios corridor.

At the time of reporting, EV Resources’ share price was $0.0090.
