Name of the Mine 
Plutonic Gold Operations.

Location
The mine is situated on 45 granted mining leases along the Plutonic-Marymia gold belt in Western Australia, extending from the Plutonic gold mine in the south-west to the Trident deposit in the north-east. Catalyst Metals consolidated the belt in 2023 following the acquisition of Vango Mining and the merger with Superior Gold Inc.

Mine Owner/s
Australian gold producer Catalyst Metals.

Brief Description
Catalyst Metals has consolidated the Plutonic gold belt, integrating high-grade mineral resources with existing mining and processing infrastructure.

This consolidation includes the operating Plutonic gold mine, its associated infrastructure, and high-grade undeveloped gold deposits along the Marymia belt. These deposits have the potential to be mined and processed through the currently underutilized processing facilities at Plutonic.

Production ore is currently sourced from the Plutonic Main underground mine. Catalyst plans to bring several satellite deposits into production over the next few years, including the Trident deposit, a high-grade resource located north-east of the Plutonic operations. 

In March 2025, Catalyst Metals achieved first stoping ore from the Plutonic East underground mine. This marks the first of three new mining operations planned to double production across the Plutonic goldbelt. The ore is expected to be processed through the existing Plutonic processing facilities. 

In January 2025, Catalyst secured underground approval for the Trident gold operation. 

Brief History
The Plutonic gold mine has been in operation since 1990.

Primary Metals/Minerals
Gold.

Secondary Metals/Minerals
Not stated.

Geology/Mineralisation
Mineralisation at Plutonic is characterised by a series of steep to flat-lying, stacked replacement-style lodes, individually up to 5 wide, hosted within ductile shear zones oriented slightly oblique to stratigraphy.

Lodes are preferentially located within the upper portion of the Mine Mafic, a sequence of upper-greenschist- to lower amphibolite-grade basaltic flows, varying in thickness between the hanging wall and footwall ultramafic units. They exhibit intense banding, defined by crude mineral segregation and alignment.

Where visible, gold is commonly associated with grey quartz veins, fine-grained arsenopyrite, and pyrrhotite.

Mineralisation is divided into four distinct styles:

• replacement – brown or Plutonic lodes, containing the bulk of the gold:
• replacement – green lodes.;
• Plutonic – hard-to-see lodes; and 
• dilatational high-angle quartz veins.

Reserves
As of June 30, 2024, total mineral reserves were estimated at 9.39-million tonnes grading 2.9 g/t gold.

In September 2024, Catalyst Metals announced a 105% increase in reserves at the Plutonic project, setting the stage for three years of production growth.  

Resources
As of June 30, 2024, total measured, indicated, and inferred mineral resources were estimated at 32.9-million tonnes grading 2.7 g/t gold.

Type of Mine
Openpit and underground.

Mining Method
Longhole retreat stoping is the predominant mining method at Plutonic.

Major Infrastructure and Equipment
The primary mining fleet includes: hydraulic backhoe excavators, haul trucks, drill rigs, dozers, graders and water carts.

Mine infrastructure comprises: transportable buildings, ablution facilities with a leach septic system, a workshop (sea containers with dome and concrete floor), a wash-down facility with oil separator, fuel tanks with a smart-fill system, detonator and explosive magazines, and explosives compound.

Prospects
Catalyst Metals is implementing a growth strategy that includes developing the K2 and Trident mines. The Trident deposit has an initial five-year mine plan, expected to produce an average of 37 000 oz/y of gold. Catalyst is undertaking an infill drilling programme to convert inferred resources, alongside step-out drilling at Trident, which could extend the mine's life beyond five years.
