Ausgold Katanning high-grade drilling: pit design and throughput notes for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Ausgold has reported a new wave of high-grade reverse circulation and diamond drilling results at its Katanning gold project (KGP) in Western Australia, pointing to potential resource growth beyond the current central zone. Intercepts from the Jinkas South and Dingo areas extend known mineralisation along strike and at depth, with multiple thick zones of +2g/t Au reported close to surface. The results support further infill and step-out drilling in 2025, with implications for expanding open-pit designs and optimising future processing plant throughput at Katanning.
Technical Brief
- Reverse circulation and diamond drilling targeted Jinkas South and Dingo satellite zones outside the current central resource.
- Several intercepts show continuous mineralised zones suitable for potential bulk-tonnage open-pit geometries.
- Drill spacing in new areas is being tightened to support conversion from Inferred to Indicated resources.
- Step-out drilling is progressively extending mineralised envelopes along strike, informing future pit shell optimisation.
- Down-dip extensions intersected by diamond holes provide structural data to refine 3D geological and grade models.
- New results will feed into updated pit designs, influencing waste:ore strip ratios and haulage profiles.
- Ausgold is sequencing further drilling to align with planned feasibility-level mine planning and plant design work.
Our Take
Gold projects in Western Australia appear frequently in our 380 gold‑keyword pieces, suggesting Katanning will be competing for capital and skilled labour against a crowded pipeline of regional developments rather than standing out as an outlier.
With 1205 Mining stories and over 2200 project‑tagged items, our coverage shows that Australian gold projects like Ausgold’s Katanning increasingly need clear scale or grade advantages to differentiate themselves in financing and offtake discussions.
The Western Australian setting for the Katanning gold project means Ausgold can likely leverage the state’s mature METS ecosystem highlighted in recent Australian Mining coverage, including local suppliers of crushing components and haulage technology that can shorten ramp‑up timelines and reduce logistics risk.
