Sunday Creek shallow antimony: design and sequencing notes for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Drilling at Southern Cross Gold Consolidated’s Sunday Creek project in Victoria has intersected high‑grade antimony directly above the planned exploration decline at the Golden Dyke prospect, confirming shallow critical mineral potential in the upper epizonal system. Six recent holes targeted the upper structural levels where antimony is expected to concentrate, complementing existing gold mineralisation and supporting a combined gold–antimony development concept. For mine planners and geotechnical teams, shallow antimony zones above decline infrastructure may influence decline alignment, ground support design and sequencing of early development headings.
Technical Brief
- New intersections confirm antimony-rich zones are vertically stacked above previously defined gold-dominant mineralisation.
- Structural targeting focused on upper-level vein and breccia systems interpreted from earlier deeper drilling and mapping.
- Geometry of the antimony lodes will now be modelled explicitly to refine three-dimensional resource wireframes.
- Shallow intercepts allow potential early antimony development without materially extending decline length or depth.
- Geotechnical domains in the upper system may differ from deeper gold zones, requiring separate design parameters.
- Metallurgical flowsheet studies must now consider optimising recoveries for a combined gold–antimony concentrate.
Our Take
Sunday Creek appears multiple times in our database as one of the few Victorian projects explicitly framed around both gold and antimony, signalling that Southern Cross Gold Consolidated is positioning it as a critical minerals play rather than a pure gold story.
The earlier coverage of PYBAR Mining Services starting the exploration decline at Sunday Creek suggests these six new holes at Golden Dyke can be rapidly followed up from underground, shortening the cycle between surface targeting and high-confidence resource definition.
