Strike Extension Drilling Validates Continuity of High-Grade Mineralisation at Eureka Northwest
During the quarter ended 30 June 2026, Javelin Minerals completed an RC drilling program of 37 holes totaling 5,184 metres aimed at extending mineralisation north and south of the planned Eureka open pit and testing down-plunge extensions. The program successfully infilled gaps in historical drilling north of the deposit, confirming consistent mineralisation patterns identified previously.
At Eureka Northwest, drilling extended the northern strike of high-grade mineralisation beneath the planned pit. Notable intercepts included EKRC036 with 4 metres at 2.7 g/t Au from 91 metres, EKRC037 with 4 metres at 2.3 g/t Au from 52 metres, and EKRC038 with 4 metres at 2.0 g/t Au from 64 metres. These results affirm the persistence of high-grade zones beyond the immediate pit limits, supporting the geological model.
Significant Eureka North Drilling Results and Near-Surface Mineralisation Identified
In the Eureka North area, key results included EKRC022 intercepting 5 metres at 2.1 g/t Au from 45 metres, EKRC020 with 10 metres at 1.2 g/t Au from 85 metres, and EKRC019 with 5 metres at 2.1 g/t Au from 67 metres. These findings confirm broad mineralisation continuity and indicate multiple mineralised horizons suitable for staged mining.
The southern deposit area also delivered encouraging near-surface results, with EKRC008 returning 4 metres at 1.6 g/t Au from 47 metres. Additional near-surface laterite mineralisation was intersected north and south of the historic open pit, including EKRC007 (1 metre at 1.0 g/t Au from 1 metre), EKRC008 (3 metres at 0.9 g/t Au from 3 metres), and EKRC018 (8 metres at 0.9 g/t Au from 4 metres). This laterite mineralisation expands accessible ore and may reduce mining costs through simpler recovery methods.
Deep Drilling Reveals Unexpected Weathering but Confirms Gold Potential at Depth
The RC program included four deep holes testing down-plunge extensions beyond 400 metres depth, exceeding previous tests limited to about 250 metres. Northern holes EKRC011 and EKRC012 encountered deeper weathering than expected, leading to RC pre-collars followed by planned diamond drill tails.
Southern deep holes EKRC009 and EKRC010 reached target depths, intersecting mineralised host structures. EKRC009 returned 1 metre at 0.4 g/t Au, confirming the deep mineralised system, while EKRC010 intersected 3 metres at 1.5 g/t Au from 278 metres, potentially indicating a separate mineralised structure east of the main system requiring further study.
Regulatory Approvals for Water Extraction and Vegetation Clearing Propel Eureka Toward Production
Javelin Minerals secured final approvals for the Water Extraction License and Native Vegetation Clearing Permit during the June 2026 quarter, critical steps for resuming mining operations. These approvals significantly de-risk the project timeline and reflect regulatory acceptance of operational plans.
The expanded Eureka Mining Lease (M24/1022), announced 26 March 2026, allows for a larger pit and infrastructure development. The Mining Development and Closure Plan (MDCP), submitted in December 2025 after the October 2025 Land Use Agreement with the Marlinyu-Ghoorlie Group, is in the final approval stage, representing the last major regulatory milestone before mining development.
Central Yilgarn Gold Project Acquisition Expands Javelin's Exploration Footprint
In addition to Eureka and Coogee near Kalgoorlie, Javelin operates the Central Yilgarn Gold Project near Sandstone, Western Australia, covering about 690 square kilometres of prospective tenure. The recent strategic acquisition in the Yilgarn region broadens the company’s exploration portfolio, though specific terms were not disclosed.
This expansion demonstrates management’s confidence in the Yilgarn Craton’s prospectivity, one of the world’s most prolific gold provinces. The Central Yilgarn project’s large landholding near Sandstone offers access to geological domains with historically significant gold mineralisation.
Coogee Gold Project Geophysical Review Identifies New Exploration Targets
Located 50 kilometres south-east of Kalgoorlie near the St Ives Goldfield, the Coogee Gold Project lies within the Kalgoorlie Terrane of the Yilgarn Craton, adjacent to major fault structures like the Lefroy Fault. A recent technical review of geophysical data identified anomalies indicative of prospective gold and copper-gold targets.
Diamond and RC drilling programs are planned to commence in the September quarter to test these targets, advancing systematic exploration and building on the region’s strong geological framework and proximity to high-grade mineralisation in the St Ives district.
Robust Cash Position and Strategic Placement Support Development and Exploration
Javelin Minerals ended the June 2026 quarter with approximately $3.9 million in cash, providing financial flexibility for ongoing exploration and near-term development at Eureka. The company has managed capital prudently while maintaining active programs across its projects.
A $1.5 million strategic placement to mining executive David Geraghty, who has become a substantial shareholder, underscores industry confidence in Javelin’s strategy and asset potential. This capital injection will bolster the balance sheet and accelerate development and exploration activities.
Eureka Mineral Resource Estimate and Production Outlook
The Eureka Gold Project’s global Mineral Resource is 2.04 million tonnes at 1.69 g/t Au, containing 110,687 ounces of gold. The Indicated Resource portion is 1.36 million tonnes at 1.8 g/t Au for 78,678 ounces. This solid resource base underpins ongoing feasibility and engineering studies aimed at production.
The project’s high-grade nature, with average grades favorable for open-pit mining in the Kalgoorlie region, combined with recent drilling confirming extensions near surface and at depth, suggests potential resource growth. Completion of the MDCP approval will enable progression to detailed engineering and economic evaluations.
Strategic Location Within Eastern Goldfields Enhances Project Viability
Javelin’s key projects are located within 50 kilometres of Kalgoorlie, a premier Australian gold mining region with established infrastructure, skilled workforce, and supportive regulatory environment. Eureka lies 50 kilometres north, while Coogee is 50 kilometres south-east near the St Ives Goldfield.
This proximity offers operational advantages including access to mining services, metallurgical facilities, and transport networks. The geological setting within the Kalgoorlie Terrane and proximity to major fault zones support Javelin’s exploration strategy and may improve economic viability by reducing infrastructure needs.
Upcoming Milestones and Development Timeline for Eureka
The next critical milestone is final approval of the Mining Development and Closure Plan, essential for transitioning from permitting to mining. The company indicated the MDCP is in its final approval phase, with completion expected in coming months.
Following MDCP approval, focus will shift to finalising engineering studies and advancing mine development. Completion of diamond drill tails at EKRC011 and EKRC012 to test northern down-plunge extensions is a medium-term exploration goal. Additionally, the September quarter drilling programs at Coogee will provide further exploration catalysts. Investors will be monitoring upcoming quarterly reports for updates on these developments and resource extension results supporting Eureka’s reserve estimates.
