Full Summary

Catalyst Metals Limited (ASX:CYL) has announced an updated Mineral Resource Estimate (MRE) for its Trident underground gold deposit located on the Plutonic Gold Belt in Western Australia. The updated MRE shows a substantial increase in both Indicated and Inferred Resources, with the total resource now estimated at 1.1 million ounces at a grade of 5.4g/t Au. The more tightly drilled Indicated Resources have increased to 633koz at 6.3g/t Au, a 20% increase on prior estimates. The mine is currently under development with an open pit recently completed to allow for the establishment of an underground portal. The company expects to begin stoping ore from the underground mine in the first half of CY2027. The Trident underground will be the fourth mine to be developed on the Plutonic Belt, joining Plutonic East, Trident open pit, and K2. Catalyst aims to increase annual gold production from ±100koz to ±200koz by developing five deposits on the Plutonic Gold Belt.

Guidance

Catalyst Metals expects to achieve ±200koz annual gold production by CY2027

Outlook

Catalyst Metals is optimistic about the Trident underground mine's potential to contribute to the company's production targets, aiming for a second, higher-grade ore source to feed the Plutonic processing plant.
