Catalyst Metals (ASX:CYL) said drill results at the Cinnamon trend at the Plutonic Gold Belt in Western Australia have increased the strike length of this higher-grade zone beneath the planned open pit by 75% to over 700 meters, according to a Wednesday Australian bourse filing.

The results were of up to 38 meters at 10.5 grams per tonne gold and 17 meters at 21.5 grams per tonne gold.

The company said Cinnamon has the potential to become a sixth underground ore source to feed the centralized Plutonic processing plant, with Catalyst's plan to increase Plutonic's gold production to about 200,000 ounces from 1.5 million ounces of reserves across five mines.

Ongoing exploration success at Cinnamon provides greater contingency and lower operating risk to the long-term plan, the company added.
