Alkane’s Kendal antimony-gold hits: mine planning and geotechnical notes
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Alkane Resources has reported multiple high‑grade antimony–gold intercepts at the Kendal prospect, adjacent to the Youle lode at its Costerfield operation in central Victoria, signalling a potentially significant extension of the narrow-vein system. The discovery targets antimony, a critical mineral used in advanced military and defence applications, alongside high-value gold grades typical of Costerfield-style mineralisation. For mine planners and geotechs, the proximity to existing Youle infrastructure suggests scope for incremental underground development and resource expansion rather than a greenfield build.
Technical Brief
- Antimony association implies complex metallurgy, likely requiring continued use or adaptation of existing Costerfield processing flowsheet.
- High antimony content flags possible deleterious-element constraints for conventional gold circuits if not carefully managed.
Our Take
Antimony appears in only a small subset of the 359 keyword-matched pieces in our database, so Alkane Resources’ Kendal results stand out in Australia, where most recent precious-metal coverage is dominated by gold-only plays.
High-grade antimony-gold intersections comparable to those at Mandalay’s Costerfield operation typically underpin narrow-vein underground mining with complex metallurgy, which can favour smaller but very high-margin operations if processing routes are optimised.
Within the 1088 Mining stories and 1995 Projects-tagged pieces, Australian antimony projects are relatively scarce, suggesting that any economically robust antimony-gold resource at Kendal could attract strategic interest from offtakers looking to diversify supply away from China-dominated sources.
