Duketon Mining Ltd Launches Drilling Campaign at Barlee Gold Project

Duketon Mining Set to Drill Six Promising Gold Targets at Barlee Project

Duketon Mining Limited (ASX: DKM) has announced the commencement of its maiden drilling campaign at the 100%-owned Barlee Gold Project in Western Australia. With drill rigs now mobilising to site, the company is preparing to test six highly-rated gold soil anomalies across approximately 5,500 metres of combined aircore and reverse circulation (RC) drilling.

The programme represents a significant milestone for DKM, targeting prospects that have never been drilled previously despite showing compelling geological signatures. Furthermore, Managing Director Stuart Fogarty emphasised the opportunity, stating these targets are of significant scale and amplitude, which makes this drilling campaign even more compelling.

"This is an exciting exploration opportunity for the Company. We have undertaken considerable work in consolidating the Barlee package and generating foundational geological datasets to identify multiple high quality targets which have never been drilled previously. These targets are of significant scale and amplitude, which makes this drill program even more compelling." – Stuart Fogarty, Managing Director

Six High-Priority Targets Ready for Testing

The drilling campaign will focus on prospects identified through DKM's 2025 geochemical sampling programme, each showing distinct gold-in-soil anomalies with substantial scale. Moreover, the systematic approach demonstrates the company's commitment to methodical exploration.

Key Observations from Target Analysis

The Gromit Prospect recorded the highest gold value at 235 ppb, whilst Lost Bolt covers the largest area at 1.7km x 1km. In addition, all targets show coherent, sizeable anomalies indicating potential bedrock mineralisation.

Notably, four of the six prospects exceed 200 ppb gold values, which is significantly above typical exploration thresholds. This demonstrates the exceptional quality of the targets identified by Duketon Mining Ltd's systematic sampling programme.

Comprehensive Preparation Phase Complete

Duketon Mining Ltd has methodically prepared for this drilling campaign over the past five months, completing essential groundwork that demonstrates the company's systematic approach to exploration. However, this thorough preparation should reduce operational risks during drilling execution.

Regulatory and Cultural Clearances

The company has secured all necessary approvals for drilling operations. Furthermore, the heritage clearance survey was completed with the Marlinyu Ghoorlie Native Title Group, ensuring full compliance with cultural requirements.

Environmental approvals have been secured for all drilling operations across the six target areas. This comprehensive clearance process eliminates potential delays during programme execution.

Technical Foundation Development

A detailed aeromagnetic survey was flown over key project areas to enhance geological understanding. Additionally, external consultant review and structural interpretation have been completed, providing valuable insights for drill targeting.

The technical work has identified additional conceptual targets beyond the initial six prospects. This suggests further drilling opportunities may emerge following the current programme completion.

Operational Readiness Achieved

Camp infrastructure has been established on-site to support the drilling programme. Moreover, access tracks have been cleared and drill pads prepared across all target areas.

Equipment mobilisation is currently underway, with drilling expected to commence within the next week. The company reports approximately 4,000 metres of aircore and 1,500 metres of RC drilling planned across the six target areas.

Understanding Gold-in-Soil Anomalies: What They Mean for Investors

Gold-in-soil sampling represents a fundamental exploration technique used to detect gold mineralisation beneath the surface. When gold-bearing rocks weather and erode, tiny gold particles disperse into the overlying soil, creating detectable "halos" above potential deposits.

Significance of Anomaly Strength

Gold-in-soil anomalies often indicate bedrock gold mineralisation below the surface. Furthermore, large, coherent anomalies like those at Barlee suggest substantial mineralised systems may exist at depth.

Values above 20-50 ppb are typically considered significant in regional exploration contexts. Consequently, DKM's targets are particularly noteworthy as they show values 4-12 times these thresholds.

Investment Implications

Virgin drilling targets with such strong surface signatures represent high-impact exploration opportunities. In addition, the combination of multiple targets with robust geochemical signatures provides Duketon Mining Ltd with several potential discovery opportunities within a single drilling campaign.

Peak gold values range from 37 ppb to 235 ppb across the six targets, with four prospects exceeding 200 ppb – well above typical exploration thresholds.

Strategic Location in Proven Gold Territory

The Barlee Project sits 200km north of Southern Cross in Western Australia's established goldfields region. This location offers several advantages for exploration and potential development activities.

Operational Benefits

Established mining infrastructure nearby provides access to skilled workforce and services. Moreover, the project is accessible via existing road networks, reducing logistical costs significantly.

Proximity to processing facilities and support infrastructure enhances the project's commercial viability. This reduces potential development costs should the drilling campaign deliver positive results.

Geological Context

The project is located within the Archaean Yilgarn Craton, which hosts numerous producing gold mines throughout Western Australia. Furthermore, regional aeromagnetic data shows favourable structural corridors that may have controlled gold mineralisation in the area.

Programme Structure and Timeline

DKM's maiden programme is designed for comprehensive target evaluation across multiple phases. However, the phased approach allows for adaptive drilling based on initial results.

Phase 1 – Aircore Drilling

4,000 metres are planned across all six prospects to test anomaly centres and define mineralised zones. This cost-effective method provides initial target assessment and geological understanding.

Aircore drilling will focus on the highest-priority targets first, with Gromit and Lost Bolt prospects receiving priority attention. Results from this phase will guide subsequent RC drilling locations.

Phase 2 – RC Drilling

1,500 metres of follow-up drilling will focus on the best aircore results to provide higher-quality samples. This enables more detailed geological and grade assessment for the most promising targets.

RC drilling provides superior sample quality compared to aircore methods. Consequently, this phase will deliver more definitive results regarding grade and geological continuity.

Expected Timeline

Drilling is scheduled to commence within one week of the announcement. Furthermore, the programme is expected to run for several weeks, with results anticipated throughout Q2 2026.

The staggered approach allows for real-time evaluation and programme adjustment based on initial results. This maximises the effectiveness of the drilling campaign budget allocation.
