EV Resources Defines High-Grade Soil Anomalies at Milton and Dollar Antimony-Gold Projects

EV Resources (ASX: EVR) has defined an 1,100-metre high-grade antimony-gold target from maiden soil geochemistry at its wholly owned Milton and Dollar projects in Nevada.

Conducted by specialty consultant Frontfinders Exploration, the survey comprised a total of 567 soil samples (324 at Milton and 243 at Dollar) grid-spaced at 100m lines with 25m stations targeting C-horizon residual regolith.

Coherent, structurally controlled mineral corridors were defined at both projects, presenting EV Resources with the first systematic target areas for further exploration across its US antimony portfolio and a clear pathway toward future drill testing.

The findings reinforce the company’s dual-track strategy of targeting near-term production in Mexico alongside a growing domestic antimony supply position as Western supply chains continue to tighten.

Milton Field Reconnaissance

Geological field reconnaissance at Milton confirmed extensive hydrothermal silicification and prominent brown-to-reddish jasperoid replacement bodies running along a primary north-to-south structural conduit.

The jasperoid zones were interpreted to represent hydrothermal replacement of carbonate host rocks along deep-seated structures.

These likely served as channels for mineralising fluids and have been considered high-priority targets for follow-up exploration.

Multi-element assays provided geochemical validation of the corridor, while statistical correlation identified Milton as an “exceptionally clean, low base-metal gold-arsenic-antimony-mercury-thallium mineral system” consistent with a Carlin-style or classic epithermal hydrothermal setting.

Multi-Element Datasets

The local geology at Dollar exhibited a more complex sedimentary-volcanic-intrusive environment with multi-element datasets separating the property into two independent premium target populations, each anchored to a key historic mine footprint.

The Dollar Mine node was characterised by elevated gold-arsenic with low base-metal signatures, with one sample returning peak anomalies of 0.415 parts per million gold and 2,080ppm (or 0.2%) antimony and a second sample extending the system footprint with a response of 1,305ppm arsenic and 0.167ppm gold.

The Resurrection node displayed a distinct silver-lead-zinc polymetallic signature, spatially separated from the gold-antimony population by ~200m of strike, and returned 17.05ppm silver paired with 932ppm antimony, 872ppm lead and a highly anomalous 2,680ppm zinc (reported to be the highest zinc value in the Dollar population).

Field mapping also identified an unmined north-south trending structural corridor near the eastern block of the Dollar tenement, which EV now considers a priority follow-up target potentially indicating a deeper mineralising system distinct from the antimony-silver-gold assemblages.

Data-Driven Framework

Managing director Mike Brown said the soil geochemistry results offered a data-driven framework for the next phase of exploration at Milton and Dollar.

“Our high-density grid sampling has delineated tightly constrained, structurally controlled corridors that line-up directly with our reconnaissance geological mapping and historic working boundaries,” he said.

“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.”

Mr Brown said that the elevated antimony across both projects was highly meaningful in light of the current US domestic shortage.

“Establishing non-reliance on sensitive, highly strategic supply chains makes secure jurisdictions like Nevada a priority for Western markets,” he added.
