Zenith Minerals Starts 1,350m RC Drilling Program Targeting Dulcie Gold Resource Growth

Drilling Program Targets Resource Growth and Grade Enhancement

Zenith Minerals Limited (ASX:ZNC) has initiated a targeted reverse circulation (RC) drilling program at its Consolidated Dulcie Gold Project in Western Australia, following the recent definition of a 21.3 million tonne inferred mineral resource grading 1.0 g/t gold for 675,000 ounces. The current campaign comprises approximately 1,350 metres across eight holes, focusing on high-confidence zones within and adjacent to the existing resource footprint.

The drilling aims to rapidly add ounces and improve grade distribution by targeting near-resource areas with strong geological continuity. Key focus areas include Dulcie South, where three holes are designed to test down-dip extensions of shallow high-grade mineralisation and close a gap in the resource model, and Scott’s Grey, where five holes seek to expand high-grade zones laterally and at depth beyond current resource limits. Historical drilling at Scott’s Grey has returned notable intercepts such as 3 metres at 7.40 g/t gold from 71 metres and 11 metres at 3.53 g/t gold from 66 metres, underscoring the potential for grade uplift.

Strategic Lease Acquisition and Regional Exploration

Zenith is progressing the acquisition and permitting of Mining Lease M77/599, which covers a critical approximately 1-kilometre strike gap between Dulcie North and Dulcie within the ~6 km mineralised corridor. This lease is considered strategically important for linking existing mineralisation and driving resource growth. Initial drilling on M77/599 is a high priority once acquisition conditions and regulatory approvals are satisfied.

Beyond the immediate resource area, Zenith controls an extensive ~360 km² landholding at Split Rocks, where multiple parallel shear zones have been identified. Historical drilling and surface geochemistry confirm gold mineralisation beyond the main Dulcie trend. The company is re-assaying a substantial dataset of historical lithium drilling samples for gold, providing a cost-effective pathway to generate new targets and potentially expand the district-scale opportunity.

Context and Development Pathways

The Consolidated Dulcie Gold Project is situated approximately 400 km east of Perth within the Southern Cross–Forrestania Greenstone Belt, a region known for significant gold endowment. The mineral resource is defined entirely on granted mining leases, facilitating development studies and potential accelerated project advancement. Zenith has consolidated control over the Dulcie corridor through ownership of Dulcie Far North and exclusive subsurface rights across Dulcie and Dulcie North, including a southern extension secured in mid-2025.

The project benefits from established infrastructure such as sealed road access, power, and water, and is within trucking distance of multiple operating gold processing facilities. Zenith is evaluating development options including staged open pit mining and toll treatment arrangements.

This drilling program follows Zenith’s recent announcement of the 675,000 ounce inferred resource at Dulcie, which more than doubled previous estimates and set the stage for further resource expansion and development planning. The current campaign’s results will feed into updated geological models to refine targeting and support subsequent drilling phases. For further context on the resource definition and its significance, Zenith’s earlier doubling of the Dulcie gold resource provides detailed background.
