Cinnamon’s New Gold Zones Could Reshape Catalyst’s 10-Year Production Plan

Exploration Breakthrough at Cinnamon

Catalyst Metals Limited (ASX – CYL) has reported a series of compelling drill results from its Cinnamon-Cobalt trend within the Plutonic Gold Belt in Western Australia. The recent drilling campaign, comprising 91 holes and over 19,000 metres of drilling, has uncovered high-grade gold mineralisation well beyond the existing resource boundaries, effectively doubling Cinnamon's known strike length to approximately 3 kilometres.

Notably, the program intercepted 33 metres at 7.4 grams per tonne (g/t) gold beneath the current resource and a remarkable 7 metres at 29.8 g/t gold approximately 1 kilometre southwest of the deposit. These results suggest significant potential to expand the resource both at depth and along strike, areas previously underexplored due to the fragmented ownership history of the Plutonic Belt.

Strategic Implications for Plutonic Gold Belt

The Cinnamon deposit, historically a modest resource of 145,000 ounces, has not been included in Catalyst's recently published 10-year production plan targeting 200,000 ounces per annum from five underground mines. However, these new drill results position Cinnamon as a promising candidate to become a sixth ore source, potentially underpinning further production growth and reserve expansion in the belt.

Catalyst's Managing Director and CEO, James Champion de Crespigny, highlighted the neglected exploration potential of the Plutonic Belt, noting that the belt's complex ownership history had hindered comprehensive drilling. The current program's success underscores the value of systematic exploration and the opportunity to unlock additional high-grade resources within this underutilised gold province.

Technical and Operational Context

The Plutonic Gold Belt spans 40 kilometres and hosts Catalyst's flagship assets, including the Plutonic Main and Plutonic East mines, which currently produce around 100,000 ounces annually at an all-in sustaining cost of approximately A$2,300 per ounce. Catalyst is actively developing three new mines; Trident, K2, and Old Highway; to double production and reserves.

The Cinnamon-Cobalt trend lies 25 kilometres northeast of the Plutonic processing plant, which remains underutilised. The recent drilling focused on deeper extensional targets and step-out areas between Cinnamon and Cobalt, revealing mineralisation hosted in sedimentary conglomerates, a different geological setting compared to the mafic and ultramafic hosts of other deposits in the belt.

Assay results were rigorously verified through multiple accredited laboratories, with quality control measures including certified reference materials, blanks, and field duplicates. The comprehensive data supports ongoing resource modelling and future mine development planning.

Next Steps and Market Outlook

Catalyst plans further drilling to delineate the extent and grade continuity of these new target areas. While Cinnamon's inclusion in production plans remains pending, the exploration upside adds a compelling dimension to Catalyst's growth narrative. Investors and analysts will be watching closely for updated resource estimates and potential revisions to the production profile of the Plutonic Gold Belt.
