About Catalyst Metals (ASX:CYL)
Catalyst Metals Limited is an ASX-listed gold producer. It operates and develops gold mines on the Plutonic Gold Belt in Western Australia and holds exploration interests north of the historic Bendigo goldfield in Victoria.
Catalyst has increased the Trident underground Ore Reserve on the Plutonic Gold Belt as mine development continues, with first ore expected in CY2027.
The ASX headline states growth of 30%; the body states Trident's underground Reserve has increased by 32% to a Probable Ore Reserve of 3.9Mt at 4.2g/t Au for 524koz, with Proved Ore Reserves nil, and an anticipated about 10 year mine life at a steady state annual production rate of 60-80koz. The update follows a June 2026 Mineral Resource of 6.2Mt at 5.4g/t Au for 1.1Moz, comprising Indicated 3.1Mt at 6.3g/t Au for 633koz and Inferred 3.1Mt at 4.6g/t Au for 448koz. Development of the Trident underground is underway with 250m of development completed. Catalyst cites past conversion of Trident Inferred Resources into Indicated at 75% and says further infill drilling is expected to increase Reserves and mine life.
The company says its September 2025 general 10-year guidance should be treated as a general guide only, given later changes to permitting timelines, Reserves/Resources, geology, operations and processing capacity. Conversion of the remaining 448koz Inferred Resource into Reserves has not yet occurred.
