A large-scale epithermal gold system with multiple growth potential
Mt Coolon Gold Project
Mt Coolon represents a large tenement package that comprises the Koala, Glen Eva and Eugenia deposits, with multiple prospects at each.
Mineral Resource (JORC)1:
- 6.65Mt @ 1.54g/t Au for 330koz
Previous exploration confirmed a large, gold-bearing epithermal system with multiple untested targets that GBM is planning to follow up.
A 2017 scoping study on the Mt Coolon Project demonstrated the technical and economic viability of open pit and underground mining of the Koala, Glen Eva & Eugenia deposits and processing and gold recovery via a combination of CIL leaching and heap leach.
