675,000 Ounces of Gold Defined at Zenith’s Consolidated Dulcie Project
Zenith Minerals has announced a maiden Inferred Mineral Resource of 675,000 ounces of gold across its Consolidated Dulcie Gold Project in Western Australia, more than doubling previous estimates and setting the stage for accelerated development.
- 675,000 oz Inferred Mineral Resource at 1.0 g/t Au cut-off
- Resource spans three granted Mining Leases: Dulcie, Dulcie North, Dulcie Far North
- Resource more than doubles previous Dulcie Far North estimate
- Entire resource on granted leases, shortening development timeline
- Next phase includes further drilling and a Scoping Study for open-pit mining
Significant Resource Upgrade
Zenith Minerals Limited (ASX: ZNC) has delivered a major milestone with the announcement of a maiden Inferred Mineral Resource totaling 675,000 ounces of gold at its Consolidated Dulcie Gold Project in Western Australia. This resource estimate, prepared in accordance with JORC 2012 guidelines, is based on 82 Reverse Circulation drill holes completed between July and November 2025 and incorporates historical drilling data.
The resource is distributed across three granted Mining Leases: Dulcie (300,000 oz), Dulcie North (75,000 oz), and Dulcie Far North (300,000 oz). Notably, the updated estimate more than doubles the contained gold previously reported at Dulcie Far North alone, highlighting the project's growing scale and potential.
Strategic Advantages and Development Pathway
Managing Director Andrew Smith emphasised the strategic significance of the resource being entirely situated on granted Mining Leases. This structural advantage materially shortens the pathway to development by reducing regulatory and tenure-related uncertainties. The scale of the resource now provides Zenith with the critical mass to confidently accelerate Scoping Study work and evaluate staged open-pit production options.
Zenith’s strong cash position and absence of debt following a recent strategic placement underpin its capacity to advance resource growth, technical studies, and development assessments without near-term funding pressure. The project benefits from established regional infrastructure and proximity to multiple operating processing facilities, further supporting accelerated development opportunities.
Next Steps: Drilling and Scoping Study
The company plans to commence an additional Reverse Circulation drilling program in April 2026. This program aims to infill southern extensions of the Dulcie corridor to enhance resource confidence and target higher-grade lodes within the stacked system to improve grade distribution. Complementary diamond drilling will collect essential structural, geotechnical, density, and metallurgical data necessary for the upcoming Scoping Study.
The Scoping Study will assess the economic potential of the Consolidated Dulcie Gold Project, exploring open-pit mining scenarios and options for toll-treatment or ore sales. This study will be a critical step in defining the project’s development pathway and unlocking value for shareholders.
Geological Context and Resource Confidence
The Consolidated Dulcie Gold Project lies within the Southern Cross–Forrestania Greenstone Belt of the Yilgarn Craton, a prolific gold province. The mineralisation occurs in a series of stacked, shallow-dipping lodes hosted primarily in amphibolite and banded iron formation units. The resource estimate incorporates rigorous quality assurance and quality control measures, including duplicate sampling and independent re-assays to address assay variance observed in recent drilling.
While the resource is currently classified as Inferred, reflecting moderate confidence, the company’s planned infill drilling aims to upgrade resource classification and support future mine planning. Some risks remain, including untested bulk density assumptions in oxide and transition zones, potential need for mining lease extensions, and metallurgical uncertainties related to pyrrhotite presence.
Bottom Line?
With a doubled resource base on granted leases, Zenith is poised to fast-track development studies, but key drilling and metallurgical results will be pivotal in defining the project's economic future.
Questions in the middle?
- How will upcoming infill drilling impact resource classification and confidence?
- What metallurgical challenges could pyrrhotite pose to gold recovery and processing costs?
- Will mining lease extensions be required to access the full resource, and how might this affect timelines?
