Killi Resources says the King Louie breccia at its Mount Rawdon West project is developing into a compelling target for a large-scale gold, copper and molybdenum-rich hydrothermal system.

Mount Rawdon West is located 20km north-west of the Mount Rawdon gold mine in the Bundaberg region.

Killi said surface sampling and mapping had established that the King Louie breccia had a strike length of about 2 km, with a distinct higher-grade core.

It originates from within a large subvolcanic centre and displays geochemical trace element associations that support an epithermal origin.

“The King Louie breccia is a major focal point for tectonic activity and the flow of gold-copper-molybdenum-rich hydrothermal fluids,” the company said.

“Identifying such a large mineralised breccia, associated with a substantial sub-volcanic hydrothermal source, drastically upgrades the prospectivity of an area that was previously interpreted as sterile granitic terrain.”

The ‘core’ of the King Louie breccia has been defined as a priority for upcoming drill testing

The company recently collected 114 soil samples over a broad 2.4km by 2.7km area.

First-pass soil sampling was conducted on a 200m by 400m grid, with infill sampling tightening to a 100m by 200m offset grid over zones of immediate geological interest.

At the same time, 25 targeted rock chip samples were collected from within the breccia and associated subvolcanic source.

Results included:

• 184.5ppb gold (MRSL0577) – intensely altered potassic rhyolitic porphyry
• 134.65ppm copper and 9.5ppm molybdenum (MRSL0578) – intensely altered potassic rhyolitic porphyry
• and 175.96ppm copper (MRSL0581) – western contact within King Louie Breccia.

Supported by a Collaborative Exploration Initiative (CEI) grant awarded by the Queensland Government, Killi’s upcoming exploration program includes:

King Louie breccia (priority gold target) – Preparations for drill-testing are actively progressing. The company is collaborating with land-use stakeholders to determine access. Scheduled for the upcoming winter to ensure safe, practical, and cost-effective operations.

Rawdon fault (copper-gold targets) – CEI grant assistance will focus on drill testing a historic copper-gold- molybdenum-bismuth anomaly

Target delineation and fieldwork – Ahead of the winter drill program, field teams will conduct infill surface sampling and detailed geological mapping to the west of the main King Louie breccia body. This work is designed to further delineate and refine the anomaly associated with the reported potassium-rich rhyolitic porphyry.
