• Catalyst Metals to join S&P/ASX 200 Index on 16 September 2025
• Replaces Brickworks Limited following its acquisition
• Flagship asset, Plutonic Gold Belt with 3.5 million ounces gold resource
• Ore Reserves of 1.0 million ounces at 3.0 g/t gold
• Plans to expand production with low capital intensity projects over next 12-18 months

Catalyst Metals Secures S&P/ASX 200 Inclusion

Catalyst Metals Limited (ASX, CYL) is set to join the prestigious S&P/ASX 200 Index effective before market open on Tuesday, 16 September 2025. This inclusion replaces Brickworks Limited, which is being removed following its acquisition and scheme approval. The move is a significant endorsement of Catalyst’s growing footprint in the Australian gold mining sector.

Strong Resource Base Anchors Growth

The company’s flagship asset is the Plutonic Gold Belt in Central Western Australia, a prolific 40-kilometre gold belt that hosts the Plutonic Gold Mine. Catalyst’s latest Mineral Resource Estimate (MRE) stands at 3.5 million ounces of gold at an average grade of 3.1 grams per tonne, supported by Ore Reserves of 1.0 million ounces at 3.0 grams per tonne. These figures underscore the quality and scale of Catalyst’s resource base.

Production Expansion with Low Capital Intensity

Over the next 12 to 18 months, Catalyst plans to bring three new mining areas into production, targeting a five-year mine life feeding its centrally located processing plant. The company highlights its low capital intensity, with total planned investments of approximately A$31 million. This strategy leverages an existing underutilised processing facility, which should help contain costs and accelerate production ramp-up.

Strategic Positioning and Market Impact

In addition to its Western Australian assets, Catalyst controls over 75 kilometres of strike length immediately north of the historic Bendigo goldfield, where it has delineated a high-grade greenfield resource averaging 26 grams per tonne. This positions the company well for further exploration success and resource growth.

The inclusion in the S&P/ASX 200 is expected to enhance Catalyst’s liquidity and visibility among institutional investors, potentially supporting a re-rating of the stock. Meanwhile, Brickworks Limited’s removal reflects the changing landscape of the index following corporate transactions.

Bottom Line?

Catalyst’s index inclusion sets the stage for increased market attention as it advances its low-capital gold projects.

Questions in the middle?

• How quickly will Catalyst ramp up production from its new mining areas?
• What impact will index inclusion have on Catalyst’s share liquidity and valuation?
• Can Catalyst replicate its resource success near the Bendigo goldfield to extend mine life?
