An extensive core hole drilling program was carried out to collect data on rock types across the Snowy 2.0 alignment. This information was collated to inform the project’s feasibility study.
The rock samples – or cores – provided geologists with a solid understanding of the geological and hydrogeological conditions. The work also identified physical properties of the existing rock.
This geotechnical program is the key to developing a final, buildable design for the Snowy 2.0 underground tunnels and power station.
