Although black shale is the dominant lithology, it also contains lighter shales and interbedded limestone layers due to sea level variation during its deposition almost 400 million years ago.

The extensions of several gold-bearing zones defined by drilling or channel sampling remain open. Strong, underexplored potential for gold in black shales and gabbro-diorite sills. The project hosts ...
