Catalyst Metals has commenced its in-mine exploration programme at the Plutonic gold underground mine located approximately 300km north-east of Meekatharra in the mid-west region of Western Australia (WA).

The exploration programme focuses on delineating resources in new zones.

Catalyst Metals has mobilised a diamond drill rig to Zone F to begin a resource delineation programme.

Zone F's location within the mine is advantageous as it can utilise existing ventilation infrastructure and is separate from current work areas, which could lead to improved operational efficiency, the company said.

The exploration programme at the Plutonic site aims to target new, unmined areas within the existing developed footprint.

The company's initial review has identified nine priority areas, all within the mine's mafic unit, which is known to host the underground mineralisation.

According to the company, tapping into these areas could enhance underground productivity and provide a buffer for mining schedules.

The exploration at Zone F is particularly focused on infill drilling at 15m intervals over an area of approximately 100m by 100m.

The company expects that the new areas could increase production as well as potentially reduce mining costs.

Catalyst managing director and CEO James Champion de Crespigny said: “Plutonic recently commissioned a third drill rig to commence exploration drilling underground at Plutonic. This drill rig will be used this calendar year to identify new sources of ore within the Plutonic underground mine.

“Production has stabilised at Plutonic but remains focused in remnant areas. Despite being reasonably successful to date in remnant mining, Catalyst recognises that new, virgin ore sources could further de-risk future operations at Plutonic.

“Catalyst has been able to identify a number of potential areas to target which if successful, should represent a low-cost, near-term source of ore.”
