Kingfisher’s Copper Blow drilling: resource, geotech and planning notes for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Kingfisher Mining has started a 3500m drilling campaign at its Copper Blow copper–gold project near Broken Hill, New South Wales, using a mix of reverse circulation and diamond holes to test extensions to existing mineralisation. Drilling is focused on defining the scale and continuity of the mineralised system to support a maiden mineral resource estimate, with step-out holes planned along strike and at depth from known intercepts. For geotechnical and mine planning teams, the diamond core will be critical for structural logging, rock mass characterisation and metallurgical sampling.
Technical Brief
- Campaign is located at Copper Blow, a copper–gold system south of Broken Hill, NSW.
- Kingfisher Mining is operator, integrating both RC and diamond rigs under a single 3500m programme.
Our Take
Kingfisher Mining’s Copper Blow drilling near Broken Hill sits alongside a recent cooperation agreement in our coverage where Kingfisher and Broken Hill Mines Limited plan to route high‑grade copper from Kingfisher’s assets into Broken Hill’s existing processing capacity, signalling a likely pathway to monetise any new intercepts without greenfield plant capex.
Within our 1243 Mining stories, copper projects in New South Wales are relatively under‑represented compared with Western Australian copper coverage, so a 3500 m campaign at Copper Blow marks Broken Hill as one of the few NSW copper‑gold exploration hubs drawing sustained attention.
For operators around Broken Hill, the combination of a copper‑gold target and access to established processing infrastructure typically improves project optionality, allowing juniors like Kingfisher Mining to pivot between toll treatment, JV structures, or staged development depending on drilling outcomes and market conditions.
