Alkane Resources 公布 Costerfield 项目 True Blue 矿床勘探进展

Alkane is pleased to announce the latest exploration results for extension and infill drilling of the True Blue deposit, located 2 km west of the active underground workings at its Costerfield Operation in central Victoria, Australia.

Program Summary

An additional 33 holes targeting the Freeman veining within the True Blue deposit have been drilled since Alkane’s previous update (ASX announcement 15 October 2025 titled ‘Costerfield Resource and Reserve Statement).
The new drilling predominantly targeted infill of the upper portion of the deposit and has significantly increased confidence in understanding the vein geometry and grade-controlling structures.
The higher resolution granted by the infill drilling indicates there is further veining complexity that serves to break-up a previously interpreted high-grade panel.
Current and future exploration drilling will target along-strike repetitions of mineralisation at True Blue both to the north and south, and investigate the link between it and the West Costerfield prospect.

11.2g/t gold and 5.7% antimony over 0.77m (ETW 0.54m) in TB055

Alkane Managing Director & CEO, Nic Earner, said: “The infill drilling of True Blue gives us the geological confidence needed to proceed with our plans for development of the deposit. The geological context gained from the drilling has also enhanced the model for further targeting along the True Blue Corridor. True Blue is certainly more complex than our original estimates, we are encouraged by the progress made and excited by the targets yet to be tested.”
