EV Resources Defines 1.1km Antimony Gold Corridor at Nevada Projects

EV Resources Nevada Antimony Gold Corridor Drill Targets Confirmed at Milton and Dollar Projects

EV Resources Ltd (ASX: EVR) has taken a significant step forward in defining the EV Resources Nevada antimony gold corridor drill targets, reporting maiden high density soil geochemistry results from its 100% owned Milton and Dollar Projects in Nye County, Nevada. According to the ASX announcement dated 7 July 2026, the work has defined a 1,100 metre continuous anomalous antimony gold corridor at Milton, aligned with mapped jasperoid outcrop, and two distinct mineralised systems at Dollar, interpreted as part of a zoned hydrothermal system, plus a new copper oxide breccia target.

The survey provides EV Resources Ltd with its first systematic, data-driven target zones across the US antimony portfolio and underpins the next phase of work aimed at generating maiden drill targets.

"The multi-element soil geochemistry results give us a clear, data-driven framework for our next phase of exploration at Milton and Dollar. The high-density grid sampling has delineated tightly constrained, structurally controlled corridors that line up directly with our reconnaissance geological mapping and historic working boundaries," said Mike Brown, Managing Director and CEO of EV Resources Ltd.

"These geochemical footprints establish a strong technical foundation as we advance our mapping, initiate geophysical surveys, and systematically refine our targets for potential drill testing. Elevated antimony across both projects is highly meaningful in the current US domestic antimony deficit."

EVR's Soil Programme in Nevada: Survey Design and Quality

The reported soil programme was carried out by Frontfinders Exploration and targeted structurally controlled antimony mineralisation. Key design features were:

• 567 soil samples in total — 324 samples at Milton and 243 samples at Dollar
• Grid spacing: nominal 100 metre line spacing with 25 metre sample intervals
• C horizon sampling: targeting residual and colluvial regolith a few centimetres to approximately 10 cm below surface
• Laboratory method: ALS AuME TL43 aqua regia digestion, 50 element suite
• Sample preparation: PREP 41, including drying, sieving to <180 microns and homogenisation
• QA/QC: blanks at approximately every 20 samples and certified reference materials, with results reported as acceptable and fit for purpose

Furthermore, the grid was designed to pick up narrow, structurally controlled systems rather than broad dispersion halos. This approach is particularly important where key elements, such as antimony, have limited mobility in soil and anomalies can be quite tight.

Milton Project: 1.1 km Gold Antimony Corridor Defined

At Milton, field reconnaissance mapped extensive hydrothermal silicification, prominent brown to reddish jasperoid replacement bodies in carbonate rocks, and a primary north–south structural corridor within Triassic Luning Formation carbonates.

The soil data are reported to validate this interpretation. Statistical analysis shows Milton as a low base metal Au–As–Sb–Hg–Tl system, described as consistent with Carlin-style or classic epithermal hydrothermal mineralisation. A key outcome is a continuous, 1,100 metre anomalous corridor defined by a cluster of premium multi-element samples.

What Makes the Premium Pathfinder Population Significant?

According to the company, 22 individual soil samples sit in the top 10% (90th percentile) for all five classic hydrothermal pathfinder elements simultaneously: gold (Au), arsenic (As), antimony (Sb), mercury (Hg) and thallium (Tl). This cluster tracks the visually mapped jasperoid trend and is considered a high confidence target zone.

Standout Milton Samples and Vectoring Elements

Selected examples from the Milton dataset reported by EV Resources Ltd include:

Two features are particularly highlighted in the dataset.

Thallium as a vectoring tool: Thallium shows the strongest correlation with antimony in the dataset, with a Spearman correlation r = 0.82. Sample M 190 has 2.45 ppm Tl against a P90 threshold of 0.73 ppm Tl, together with 0.118 ppm Au, making it a key node for follow-up structural mapping and rock sampling.

High-grade mercury node: Sample M 162 returned 5.44 ppm Hg, stated to be approximately 30 times the dataset median, combined with 121.5 ppm Sb and elevated copper. Consequently, the company interprets this as a potential sub-surface structural trap or blowout zone, flagged for immediate follow-up.

Field observations described in the announcement support a structurally controlled system, with intensive silicification, well-developed jasperoid bodies, north–south structural control, carbonate-hosted alteration and quartz veining. These features indicate that mineralising fluids have moved along specific structures, replacing carbonate rocks and leaving silica-rich zones that are now key targets.

Dollar Project: Two Mineralised Systems and a Zonation Model

According to the ASX announcement, the Dollar Project contains a more complex geological setting with sedimentary, volcanic and intrusive rocks. The soil data distinguish two separate target populations, each linked to historic workings:

1. Dollar Mine Node (northern zone): gold–antimony system
2. Resurrection Node (southern zone): silver–lead–zinc–antimony system

The company's technical team interprets the pattern as a vertical and lateral hydrothermal telescoping zonation, where different metals were deposited at different levels or parts of the system along a shared structural pathway.

Dollar Mine Node: Gold Antimony in the North

The Dollar Mine Node sits over the historic Dollar Mine workings and is characterised by elevated gold (Au) and arsenic (As), alongside lower base metal content compared with the southern zone.

Key soil samples reported include:

Sample D 094 is important in an exploration context, with 0.415 ppm Au and 2,080 ppm Sb, equivalent to 0.2% Sb in soil. Such grades in soils are often considered strong pathfinder anomalies and can justify detailed follow-up.

Resurrection Node: Polymetallic Silver Base Metal System

Approximately 200 metres south of the Dollar Mine Node, near shaft PB39, the Resurrection Node shows a distinct metal association featuring elevated silver (Ag), lead (Pb) and zinc (Zn), with antimony still present as part of a broader polymetallic suite.

The presence of these values in soil directly above historic workings suggests a robust geochemical footprint for silver and base metals that may align with subsurface structures.

Hydrothermal Telescoping at Dollar: What Does It Mean?

Hydrothermal telescoping refers to a situation where mineralising fluids of different temperatures and compositions move along the same structures, depositing different metals at different depths or positions. Higher-temperature fluids at deeper or more central parts of the system typically deposit metals such as gold, arsenic and antimony, while lower-temperature fluids at shallower or more distal positions deposit silver, lead and zinc.

At Dollar, EV Resources Ltd reports a polymetallic Ag–Pb–Zn–Sb zone in the south transitioning over roughly 200 to 300 metres of strike into a gold–arsenic–antimony corridor to the north. A strong correlation between antimony and gold (Sb–Au r = 0.76) indicates they commonly occur together, whereas a weak correlation between silver and gold (Ag–Au r = 0.15) suggests they are largely independent.

This supports the interpretation of two related but distinct geochemical associations along a shared structural trend. For investors, such systems can be attractive because they may host multiple metal domains that could be evaluated separately or in combination, depending on future drilling outcomes.

Key Exploration Concepts Used at Milton and Dollar

The Nevada work by EV Resources Ltd uses several technical ideas common in early-stage exploration. Understanding these concepts can help investors assess similar announcements.

What Are Pathfinder Elements?

Pathfinder elements are trace elements that move more easily away from a mineralised source than the main commodity. For gold systems, common pathfinders include arsenic (As), antimony (Sb), mercury (Hg) and thallium (Tl). Elevated levels in soil can indicate proximity to buried mineralisation, even where gold itself is only weakly anomalous.

What Is a Jasperoid and Why Does It Matter?

A jasperoid is a rock formed when silica-rich fluids replace carbonate rocks, creating hard, often reddish or brown silica-rich bodies. In Nevada, jasperoids are commonly associated with Carlin-style and epithermal gold deposits. Where jasperoid bodies follow specific faults or fractures, they can mark important fluid pathways.

Why Use Soil Geochemistry?

Soil geochemistry samples the fine fraction of soil to measure the content of metals and trace elements. For structurally controlled deposits:

• Tight sample spacing (for instance, 25 metres along lines) is used to trace narrow mineralised structures
• Statistical analysis of multi-element data helps distinguish meaningful anomalies from background noise
• Correlation analysis (for example, Sb–Tl r = 0.82) helps understand which elements move together and can guide vectoring towards the core of a system

What Is Induced Polarisation (IP)?

Induced polarisation is a geophysical method where an electrical current is passed into the ground and the way rocks temporarily hold and release charge is measured. Sulphide minerals commonly respond strongly to IP surveys. In systems like Milton and Dollar, IP can help identify sulphide-rich zones or faults at depth that link to the soil anomalies.

New Copper Oxide Breccia Target in the Dollar Southeast

Beyond the two main antimony-related systems, field mapping at Dollar has identified a north–south trending copper oxide breccia in the southeastern part of the tenement. Reported features include heavily silicified and weathered breccia outcrop, visible secondary copper oxide mineralisation at surface, and a structural trend broadly parallel to the eastern tenement boundary.

EV Resources Ltd considers this copper overprint a priority follow-up target, potentially linked to a deeper mineralising system that is separate from the main antimony, silver and gold associations. In addition, this discovery adds a copper component to the broader project-level metal mix.

Planned Work: Pathway to Drill Target Definition

The ASX announcement outlines a staged programme to move from soil anomalies to drill targets at Milton and Dollar, integrating soil data, mapping, rock sampling and geophysics.

Step 1 – Focused Structural Rock Chip Sampling

Field teams will conduct high-density rock chip and channel sampling across exposed jasperoid ridges at Milton and across the copper breccia and key structures at Dollar. The objectives are to confirm in situ grades in rock versus soil responses and to better define structural orientations and controls.

Step 2 – Ground Geophysics at Milton

The company will review appropriate methods and costs for high-resolution electrical geophysics, particularly induced polarisation and resistivity. The planned survey will focus on the 1.1 km Milton jasperoid trend, aiming to locate fluid conduits and faults at depth and identify areas with sulphide concentrations that might relate to stronger mineralisation.

Step 3 – Drill Target Generation

Subsequently, EV Resources Ltd will integrate existing historical information, newly defined soil anomalies, rock sample results and future geophysical data to build a prioritised maiden reverse circulation or diamond drilling programme across both projects.

For investors following EV Resources Ltd, each of these stages represents a catalyst where new information can materially change geological understanding and perceived project risk.

EV Resources Ltd: Nevada Within a Wider Antimony Portfolio

The ASX announcement also places the Milton and Dollar results within the broader portfolio of EV Resources Ltd, described as a critical minerals exploration and development company focused on securing North American antimony supply. The EV Resources Nevada antimony gold corridor drill targets sit alongside meaningful progress in Mexico.

In Mexico, EV Resources Ltd is advancing the Tecomatlán processing plant, where refurbishment and installation of a gravitational concentrator circuit is underway. Furthermore, the Los Lirios antimony project — a high-grade carbonate replacement deposit style system approximately 50 km from Tecomatlán — has first-pass drilling complete with work progressing towards a maiden JORC Mineral Resource.

In the United States, the company owns the Milton and Dollar Projects in Nevada through a US subsidiary. These are described as 100% owned and positioned to support the US domestic critical minerals supply chain, with antimony already designated as a critical mineral by the US, EU and Australia.

The Nevada soil results contribute to this broader positioning by delivering defined 1.1 km Au–As–Sb–Hg–Tl anomalies at Milton and a zoned gold–antimony and silver–base metal system at Dollar, with an additional copper oxide target. These outcomes give EV Resources Ltd a clearer technical framework to advance its Nevada assets towards quantitatively defined corridors being prepared for geophysical testing and, in due course, scout drilling.
