Everest Metals Launches 2,000m EIS-Supported Drilling at Mt Dimer Gold Project in WA

WA Government’s EIS Grant Supports 2,000m Drilling at Mt Dimer

Everest Metals confirmed the start of its 2,000-metre reverse circulation drilling program at the Mt Dimer Exploration Project (E77/2383), supported by the WA Government’s Exploration Incentive Scheme Round 32. Awarded in late October 2025, the co-funding grant reimburses up to 50% of direct drilling expenses, capped at A$145,000. This government assistance significantly lowers the company’s exploration capital requirements in the area.

The drilling targets three high-priority gold anomalies within the tenement. The program involves 16 reverse circulation holes drilled to depths of up to 120 metres to evaluate these targets. Drilling was projected to conclude within two weeks of the announcement, with assay results expected by September 2026—key information for investors tracking exploration progress.

Prime Location Between Two Active Gold Mines

The Mt Dimer Exploration Project (E77/2383) is located in WA’s Goldfields, about 150 km northwest of Kalgoorlie and 120 km northeast of Southern Cross. The tenement is positioned 1.5 km west of Everest Metals’ fully owned Mt Dimer-Taipan Gold Mining Project and 4 km east of Beacon Minerals Ltd’s Mt Dimer Gold Mining Project. This places the exploration area between two active gold mining operations along the same geological structure, underpinning the exploration strategy.

Beacon Minerals’ adjacent Mt Dimer project contains an Inferred and Indicated mineral resource of 440,000 tonnes at 3.6 g/t gold, highlighting the district’s gold potential. Everest Metals’ Mt Dimer-Taipan project holds a Maiden Inferred Mineral Resource Estimate of 722,000 tonnes at 2.10 g/t gold (48,545 ounces), plus 89,011 ounces of silver at 3.84 g/t. Company leadership expresses confidence that the mineralised gold system mined at these neighbouring sites extends into the exploration tenement.

Historical Geochemical Surveys Identify Three Major Gold-Arsenic-Lead Anomalies

Exploration targets within E77/2383 are supported by both historical and recent geochemical sampling. A 2021 soil geochemical survey confirmed earlier findings, with gold assays up to 430 parts per billion and arsenic levels reaching 420 parts per million. These results delineated three significant gold-arsenic-lead anomalies across the tenement. The spatial correlation of arsenic, lead, and gold in soil samples guided the prioritisation of these targets for drilling.

Target zones in E77/2383 and the neighbouring M77/515 mining lease were identified through integrated mineral mapping, structural analysis, and geochemical data. This multidisciplinary approach suggests potential for orogenic gold and banded iron formation (BIF)-hosted mineralisation within the tenement, supporting the hypothesis that mineralisation extends beyond current mining lease boundaries.

May 2025 Scout Drilling Validated Additional Gold Potential

Before the current EIS-supported campaign, Everest Metals conducted scout reverse circulation drilling in May 2025 on E77/2383. This initial program tested two high-priority anomalies in the northwest and southeast parts of the tenement, drilling two inclined holes at 60 degrees to 120 metres depth. Results from this preliminary drilling informed the design of the ongoing 2,000-metre program and helped identify further targets.

One key target, Anomaly A, spans approximately 700 by 300 metres and was selected based on geological features including strong iron oxide and silica responses, hydrothermal alteration in mafic intrusions, a prominent north-south strike-slip fault, radiometric anomalies, and coincident gold-in-soil anomalies. Scout holes at Anomaly A yielded promising results: Hole TE25-01 intersected 9 metres at 0.33 g/t gold from 13 to 22 metres, while Hole TE25-02 returned 2 metres at 0.34 g/t gold from 17 to 19 metres and 3 metres at 0.32 g/t gold from 92 to 95 metres. These gold zones are associated with quartz veins in felsic volcanic rocks showing clay alteration, possibly related to a shear zone.

Geological Evidence Supports Orogenic Gold and BIF Mineralisation Models

The geological framework at Mt Dimer supports two main mineralisation models: orogenic gold and banded iron formation-hosted gold. Analysis of Anomaly A revealed geological and geochemical characteristics consistent with both models, similar to those observed at nearby Mt Dimer operations by Beacon Minerals and Everest Metals. Integration of structural mapping, radiometric data, and soil geochemistry shaped the current drilling plan and target prioritisation.

In scout drill hole TE25-02, deeper intervals intersected mafic and ultramafic rocks with iron-stained quartz veinlets, indicative of gold mineralisation at depth. These findings suggest orogenic gold systems may extend deeper than previously tested. The broader Mt Dimer-Taipan area remains largely underexplored, with early results indicating strong potential for concealed gold deposits. The ongoing 2,000-metre drilling program employs a systematic approach informed by soil geochemistry, structural interpretation, and mineral mapping to identify economic gold mineralisation.

Mt Dimer-Taipan Mining Lease Boasts Long-Term History and Resource

Everest Metals’ Mt Dimer-Taipan mining lease (M77/515) has a mining and exploration history dating back to 1992. The company acquired the project in 2020, along with the adjacent exploration tenement E77/2383 to the west. This mining lease is Everest Metals’ core asset in the Mt Dimer district and evidences the economic viability of gold mining in the region over decades.

The Mt Dimer-Taipan project’s Maiden Inferred Mineral Resource Estimate, reported in 2021 under JORC Code 2012, comprises 722,000 tonnes at 2.10 g/t gold, equating to 48,545 ounces of gold. The resource also includes 89,011 ounces of silver at 3.84 g/t. The estimate applies a 1.0 g/t gold cut-off below 380 metres relative level. This resource base confirms the gold potential within Everest Metals’ tenure and supports exploration in the adjacent tenement where similar mineralisation is expected.

Drilling Completion and Assay Results Expected by September 2026

Everest Metals reported that the 2,000-metre reverse circulation drilling program at Mt Dimer was expected to conclude within two weeks of the late July 2026 announcement. The drilling of 16 holes to depths up to 120 metres systematically tests the high-priority anomalies identified across the tenement. Investors will closely watch for assay results anticipated in September 2026.

The outcome of this drilling will be critical for assessing exploration success and potential resource definition at Mt Dimer. Significant gold intersections comparable to or exceeding scout drilling could justify further drilling and resource estimation. Conversely, results below expectations may prompt reassessment of exploration strategies. The EIS co-funding arrangement reduces the company’s financial exposure, enabling efficient capital allocation.

WA Government’s EIS Funding Highlights Gold Exploration Priority

The WA Government’s Exploration Incentive Scheme Round 32 co-funding of the Mt Dimer drilling program underscores the strategic importance of gold exploration in Western Australia. The EIS reimburses up to 50% of direct drilling costs, capped at A$145,000, encouraging systematic exploration in prospective areas and supporting the state’s mineral resource development.

Executive Chairman and CEO Mark Caruso acknowledged the government’s support, describing the co-funded drilling as an "exciting opportunity to advance exploration at the Mt Dimer Exploration Project." For junior explorers with limited capital, such cost-sharing arrangements significantly enhance exploration capacity by halving drilling expenditures.

Investment Insights and Exploration Risks

Prospective investors should recognize that exploration activities, including the current Mt Dimer drilling, carry inherent risks and uncertainties. While geological and geochemical indicators suggest gold mineralisation, drilling results may not confirm economic deposits or lead to resource definition. The encouraging scout drilling results do not guarantee similar or larger gold zones in the systematic program. Exploration success in the Kalgoorlie district, though historically positive, remains subject to geological variability and technical challenges.

Monetizing any exploration success depends on establishing a mineral resource estimate, demonstrating economic viability through feasibility studies, obtaining regulatory approvals, and stable commodity prices. Adjacent mining operations by Beacon Minerals and Everest Metals’ Mt Dimer-Taipan project confirm technical and economic feasibility in the region, but each deposit’s unique geological and market conditions must be considered. Current exploration results represent early-stage evaluation without assurance of economic development.
