 Drilling at Old Highway confirms resource growth potential
Key Points
  • Drilling results demonstrate potential for Resource growth in areas adjacent to existing mine plan
  • Further drilling will target down dip extensions of Reserves and Resources
  • Old Highway will be the fifth deposit to be developed by Catalyst to grow gold production from ±100koz pa to ±200koz pa
Full Summary

Catalyst Metals Ltd (ASX:CYL) has reported drilling results from the Old Highway gold deposit, located 40km south of the Plutonic processing plant in Western Australia. The results demonstrate the potential for resource growth in areas adjacent to the existing mine plan. The latest drilling program targeted down-dip and up-dip extensions outside of the current resource envelope, returning several high-grade intercepts. These results, combined with previous deeper, down-dip drill results, indicate the potential to expand the underground reserve and resource at Old Highway. Catalyst is currently progressing approvals for Old Highway's development, which will mirror the company's Trident development - an initial small, self-funded open pit followed by a longer life, high-grade underground mine. Old Highway will be the fifth deposit to be developed by Catalyst as part of its plan to grow gold production from the Plutonic Gold Belt from ±100koz pa to ±200koz pa. The proximity of Old Highway to Plutonic's processing plant allows Catalyst to lower the development costs of the project.

Guidance

Catalyst is targeting to grow Reserves and production from 1.5Moz to ±2Moz and ±100koz to ±200koz annually across the Plutonic Gold Belt.

Outlook

Catalyst is aiming for the Plutonic Gold Belt to have a 10 year mine life, a unique and rare proposition for an underground Western Australian gold mine.
