Why did this ASX 200 gold stock jump?
Investors were buying the gold miner's shares after it revealed a significant new high-grade discovery at its Plutonic Gold Belt in Western Australia.
According to the release, strong new drilling results have been achieved at the Cinnamon trend, located around 25 kilometres from the Plutonic processing plant.
The company notes that its latest drilling has confirmed a high-grade gold zone over a 400-metre strike length beneath the existing Cinnamon open pit resource. Importantly, this zone remains open both along strike and at depth, which highlights clear potential for further expansion as drilling continues.
The newly reported drill intercepts included standout results such as 18 metres at 9.7 grams per tonne of gold, 19 metres at 4.1 grams per tonne of gold, and 30 metres at 2.9 grams per tonne of gold.
The ASX 200 gold stock highlights that these results build on earlier high-grade intersections that were reported in October. This includes 33 metres at 7.4 grams per tonne and 22 metres at 14.3 grams per tonne.
While Cinnamon is currently an undeveloped open pit resource of 145,000 ounces, today's announcement changes the investment narrative.
Management believes Cinnamon could now support a standalone underground mining operation, potentially becoming Plutonic's sixth ore source. This would add further optionality and flexibility to the production profile, while helping underpin the company's target of lifting annual gold production from ~100,000 ounces to ~200,000 ounces.
It is worth noting that Cinnamon is not included in Catalyst Metals' existing 10-year production plan, meaning any successful development could represent upside beyond current forecasts.
Commenting on the news, the ASX 200 gold stock's managing director and CEO, James Champion de Crespigny, said:
Since Catalyst acquired Plutonic, it has only had the time and capital to explore at Plutonic and Trident. Both Reserves have doubled under Catalyst's ownership. The next target was Cinnamon. The results today, and those released back in October 2025, suggest the potential to replicate this success again. What is also exciting is that we are awaiting further results from K2 and Old Highway – two attractive prospects. The 2025 financial year had a strong focus on exploration at Plutonic and to date, this seems to be delivering results.
