AIC Eloise high-grade gold hit: geometry and design notes for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
AIC Mines has reported one of its highest-grade gold intersections at the Eloise South prospect in north Queensland, with diamond drilling returning 3.2m at 92.5g/t gold, including a 1.2m interval at 249g/t, just two kilometres south of the operating Eloise copper mine. The intercept lies within the broader Eloise tenement package, where existing underground infrastructure and services for copper provide potential synergies for future gold development. For resource geologists and mine planners, the narrow but ultra-high-grade zone raises questions on continuity, stope geometry, and ground support design in a mixed copper–gold setting.
Technical Brief
- Proximity to current decline, power, ventilation and dewatering offers brownfield access for any future gold stopes.
- Brownfields setting enables potential shared hoisting, pastefill, and back‑of‑house infrastructure, reducing capital intensity.
- Mixed copper–gold system implies variable sulphide content, influencing ground conditions, support corrosion and backfill chemistry.
- Narrow ultra‑high‑grade lode geometry will drive tight drilling spacing to resolve continuity and stope shapes.
- Any future mine design must integrate with current Eloise copper schedules to avoid ventilation and haulage bottlenecks.
- For similar mining brownfield discoveries, integration of geotech domains with existing seismic and stress data is critical.
Our Take
AIC Mines’ recent decision to accelerate the Eloise plant expansion to 1.5Mtpa suggests that high‑grade gold at the Eloise South prospect could be blended through existing copper circuits rather than requiring standalone gold infrastructure, improving capital efficiency.
Our database shows multiple recent AIC items centred on north Queensland copper (Eloise and Jericho), so the emergence of such high‑grade gold there likely enhances project optionality in mine planning, allowing prioritisation of stopes that maximise early cash flow while the processing expansion beds down.
