Catlalyst Metals’ Trident Reserve grows by 30%; ongoing infill drilling of 448koz inferred Resource expected to further grow Reserves

 

 

Catalyst Metals Limited (Catalyst or the Company) (ASX:CYL) is pleased to provide an updated Ore Resource estimate for the Trident underground gold deposit, located on the Plutonic Gold Belt in Western Australia.
.
A large part of the Resource growth came from inferred material, reflecting the focus on Resource extension drilling over the past 12 months. Trident currently has a +10 year mine life and in time, infill drilling will target further conversion of inferred Resources to indicated, and subsequently Reserves.

• Trident’s underground Reserve has increased by 32% to 524koz at 4.2g/t Au, with
an anticipated ±10 year mine life at a steady state annual production rate of 60-80koz
• This is another step toward Catalyst’s 2Moz Reserve target to support a long-term
±200koz annual production rate
• In June 2026, Catalyst released an updated Resource at Trident of 1.1Moz at 5.4g/t Au
• Resource growth over the past 12 months at Trident came largely from new inferred
Resources, as drilling sought to test extensions of the exiting deposit.

Inferred Resources at Trident are 448koz
• In the past, Trident’s inferred Resources have had a 75% conversion into indicated.
Further infill drilling is expected to increased Reserves and extensions to mine life
• Development of the Trident underground mine is currently underway with 250m
of development completed. First ore is expected in CY2027
• Trident is currently the second-largest deposit on the Plutonic Belt. It is expected to form
a second, higher grade base load ore source to the central Plutonic processing plant
as part of Catalyst’s plan to increase annual gold production from ±100koz to ±200koz3
• The Trident underground will be the fourth mine to be developed on the Plutonic
Belt, the first three being Plutonic East, Trident open pit and K2
• In September 2025, Catalyst released general 10-year guidance. Since then, Catalyst has, understandably, seen changes to permitting timelines, Reserves/Resources, geological understanding, operational delays and processing capacities
• As a consequence, the September 2025 guidance should be seen as a general guide as to the management’s long-term plansfor Plutonic Belt’sfuture production. Future
guidance will update to reflect new changes being observed

Historically, infill drilling of inferred Resources has had a conversion rate of around 75% to indicated. The Trident Reserve is another step toward Catalyst’s target of defining a ±2Moz Reserve across Plutonic to support a long-term, sustained production rate of ±200koz per annum for 10 years.
