Zenith Minerals grows Dulcie gold project resource by 41%

Zenith Minerals (ASX: ZNC) has announced a substantial increase in gold resources at its 100%-owned Dulcie Far North (DFN) project in Western Australia.

The mineral resource — all in the inferred category — is estimated at 8.2 million tonnes grading 1.15 grams gold per tonne, for 302,000 oz. of gold. The contained metal is 41% higher compared to the previous resource estimate in December 2024.

The resource upgrade, Zenith said, was driven by extension and infill drilling of previously defined lodes, as well as the identification of new ones. It follows the recent completion of 37 reverse circulation holes completed between February and April.

“This mineral resource upgrade marks a turning point for Zenith at Dulcie,” Zenith’s managing director Andrew Smith stated, as it “confirmed the potential for a much larger system through the identification of new footwall lodes and stacked structures.”

The next step for the DFN project, he added, is to conduct follow-up drilling in the third quarter to test open extensions along strike and at depth, and to further delineate the newly identified gold-bearing footwall lodes.

Consolidated project

According to the company, the resource update represents “a key milestone” in the broader consolidation of its Dulcie gold project.

Located 400 km east of Perth, the Dulcie property comprises a contiguous group of mining leases spanning over 6 km. Zenith initially obtained the DFN mining lease in January 2023. Since then, it says it has more than doubled the gold resource from 150,000 oz. to over 300,000 oz.

This month, the Australian explorer acquired additional subsurface rights that represent a 3 km southern extension to DFN. The new mining rights, it says, grant Zenith the exclusive rights to explore and develop mineralization from more than 8 metres below surface across the 3 km strike, directly along trend
from DFN.

This ground, which was partially drill-tested by Zenith in 2020–2021, enhances the
company’s strategic landholding, permitting framework, and development potential, the company added.
