Nova Minerals advances major 2026 drill and antimony development program

Nova Minerals Limited CEO Christopher Gerteisen joined Steve Darling from Proactive to provide an update on the company’s planned 2026 field season and advancing antimony development initiatives at its flagship Estelle Gold and Critical Minerals Project in Alaska. The company is moving toward the Feasibility Study stage while simultaneously progressing pilot-scale antimony production targeted for late 2026 to early 2027.
Gerteisen explained that Nova Minerals is preparing for one of the largest exploration and development campaigns in the company’s history, with activities focused on resource definition drilling at the RPM deposit, continued advancement of the Stibium and Styx antimony prospects, and ongoing permitting and environmental work designed to support future mine development.
The 2026 programs are fully funded, with more than US$60 million available through existing cash reserves and funding support from the Department of War (DoW). Management noted that the strong financial position provides flexibility to accelerate development and exploration activities as required throughout the field season.
A major component of the 2026 campaign will be an extensive drilling program totaling up to 10,000 metres across the Estelle Project. Up to three diamond core drill rigs are expected to operate simultaneously, focusing on high-priority infill and expansion drilling at the RPM gold deposit while also continuing targeted drilling initiated last year at the Stibium antimony prospect. The Stibium work is specifically aimed at advancing exposed stibnite vein systems and improving resource delineation.
The drilling campaign will be supported by a broad regional exploration program that includes geological mapping, reconnaissance sampling, soil grid surveys, and excavation of exposed stibnite-bearing ore veins. Key target areas include RPM, West Wing, Stibium, Portage Pass, and Styx, where additional bulk sampling activities are planned to further evaluate antimony mineralization.
Operations are expected to run continuously for at least three months during the Alaskan summer season, taking advantage of nearly 24-hour daylight conditions to maximize drilling productivity seven days a week. Gerteisen emphasized that the program remains flexible and may be adjusted as new geological observations and drill core results become available throughout the campaign.
