Catalyst Metals discovers high-grade gold zone at Cinnamon open pit

Catalyst Metals (ASX:CYL) announced the discovery of a high-grade gold zone beneath the existing Cinnamon open pit resource, marking a potential sixth underground ore source for the Plutonic Gold Belt.

Cinnamon, located 25km from the underutilised Plutonic processing plant, currently hosts an open pit resource of 145,000 ounces of gold.

Initial drilling in October 2025 intersected 33m at 7.4 g/t Au, opening a 400-metre target area of high-grade mineralisation.

Follow-up drilling has confirmed continuity along this 400-metre strike, with results including 18m at 9.7 g/t Au, 19m at 4.1 g/t Au, 20m at 2.9 g/t Au, and multiple other intercepts, all demonstrating significant mineralisation at depth.

Catalyst plans further drilling to test the limits of the zone both along strike and at depth, alongside infill drilling to define the resource.

The Cinnamon trend, a largely underexplored 3km sequence of sedimentary host rocks, offers substantial growth potential, complementing Catalyst's existing underground mines at Plutonic Main, Plutonic East, Trident, K2, and Old Highway.

Catalyst CEO James Champion de Crespigny highlighted that the results at Cinnamon provide a tangible pathway for future production growth and optionality, supporting the company's 10-year plan targeting 200,000 ounces of annual gold production.

Under Catalyst's stewardship, Plutonic reserves have already tripled since 2025, and ongoing exploration success at Cinnamon, K2, and Old Highway continues to strengthen the company’s growth pipeline, while studies are underway to assess restarting the second processing plant to accommodate potential expansion.
