Alkane’s Nagambie antimony–gold drilling: geometry and design notes for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Alkane Resources has started diamond drilling at the historic Nagambie mine in Victoria under an earn-in agreement with Nagambie Resources, targeting expansion of the antimony–gold resource. The initial program covers mining licence MIN 5412 and exploration licence EL 5511, marking the first exploration phase that could lead to a formal joint venture. For geologists and mine planners, the work will refine antimony–gold grade distribution and geometry, informing potential underground designs and metallurgical testwork for complex Au–Sb mineralisation.
Technical Brief
- Diamond drilling implies oriented core potential, enabling structural controls on Au–Sb lodes to be modelled.
- Earn-in structure means Alkane funds staged work programs before any capex on mine redevelopment.
- Work on both MIN 5412 and EL 5511 allows integration of near-mine and regional targets.
- Joint venture pathway concentrates early technical risk in drilling and resource definition rather than plant commitments.
Our Take
Alkane Resources’ recent record quarterly net profit of $93 million and cash, bullion and listed investments of $374 million suggest it has the balance sheet strength to fund aggressive JV work across Nagambie’s MIN 5412 and EL 5511 without immediate reliance on equity raisings.
Within our mining-projects coverage, antimony appears in far fewer items than gold, so Alkane’s move into Victorian antimony–gold ground positions it in a relatively uncluttered segment where any defined resource could attract strategic interest from downstream users seeking non‑Chinese supply options.
