Highlights

  • Egina Gold Corridor exploration advancing in WA's Yilgarn Craton greenstone belt setting
  • Step-out drilling testing extensions to known gold mineralisation along strike and at depth
  • Yilgarn Craton is Australia's most prolific gold province, hosting the Golden Mile and multiple major mines
  • Elevated AUD gold price underpins exploration investment in Yilgarn greenstone belt discoveries

Duketon Mining Limited (ASX:DKM), trading at A$0.10 as at 30 October 2026, is a Western Australian gold explorer conducting systematic exploration of the Egina Gold Corridor within the Yilgarn Craton, Australia's most significant Archean greenstone belt province and home to the country's greatest concentration of gold mines, with the Company's step-out drilling campaign designed to extend known gold mineralisation and grow the resource base at the Egina project toward a development-scale target.

Egina Gold Corridor: Yilgarn Exploration Target

The Egina Gold Corridor is Duketon Mining's primary exploration asset, located in the Yilgarn Craton region of Western Australia in a greenstone belt setting hosting gold mineralisation in geological associations common to the Yilgarn – including shear zone-hosted lode gold, intrusion-related gold, and greenschist facies host rocks that are characteristic of the major Yilgarn gold camps. The Egina area has been subject to historical exploration by previous tenement holders, and Duketon has been re-evaluating the exploration database and conducting new systematic work programs to identify the full extent and potential of the gold system within its tenure. The Company's drilling has intersected gold mineralisation at multiple positions within the corridor, confirming the presence of a gold system with potential for resource definition.

Yilgarn Craton: Australia's Premier Gold Province

The Yilgarn Craton of Western Australia is Australia's most significant gold producing province and one of the world's most prolific Archean gold terranes. It hosts the Kalgoorlie Goldfields – the Golden Mile, one of the richest gold deposits ever found – as well as hundreds of other gold mines and deposits across the Eastern Goldfields, Southern Cross, and Murchison sub-provinces. The geological understanding of gold mineralisation controls in the Yilgarn is among the most advanced of any gold province in the world, providing a strong exploration model framework for targeting new gold discoveries in greenstone belts adjacent to or along strike from existing mines. Duketon's position in the Yilgarn places it in a proven geological environment for gold discovery.

Step-Out Drilling: Resource Growth Strategy

Duketon Mining's primary exploration activity at Egina is a step-out drilling campaign designed to test extensions to known mineralisation along strike and at depth from drill holes that have previously returned positive gold intercepts. Step-out drilling is the primary tool for growing a gold resource from an initially defined zone to a potentially development-scale target, and the pace of resource growth is a function of the geological continuity of the gold system and the drilling investment made to test it. Duketon is funding its current drilling program through a combination of available cash and has maintained a lean corporate cost structure to maximise the proportion of expenditure directed to exploration.

Market Conditions and Gold Price Support

The extraordinary Australian dollar gold price environment of 2025 and 2026 – with AUD gold sustained above A$4,500 per ounce – has fundamentally improved the economics of Western Australian gold exploration and development. At these gold prices, gold mineralisation of moderate grade and appropriate geometry can support development economics that generate strong project returns, expanding the universe of economically viable discoveries and supporting investor appetite for early-stage gold explorers like Duketon Mining. The elevated gold price also attracts corporate development interest from mid-tier and major gold producers seeking to acquire near-term production growth through the acquisition of advanced exploration projects.
