ShapshotThe Canterbury mine which closed in 2021 has been transformed through earthworks and restorative planting that have rehabilitated the site into being suitable for its former uses of pastoral farming and plantation forestry.

During the year, final rehabilitation of the mine progressed with equipment operators completing rehabilitation earthworks in January 2023. Post-completion of all rehabilitation earthworks, identification of, and planning for required maintenance obligations and ongoing monitoring activities have been occurring.

Summary:

The project is located in the Canterbury Coalfield, Malvern Hills, New Zealand.

The defined resource is contained within the late Cretaceous to Early Paleocene aged Broken River Formation., formed during the Tertiary transgressive-regressive cycle between the Rangitata and Kaikoura Orogenys.

Overlying the coal measures is the Conway Formation, dominated by micaceous and quartz rich fine sandstones and mudstones indicative of littoral to shallow marine settings.

Pleistocene aged glacial outwash gravels and tills mask underlying stratigraphy over much of the area. Younger river gravels also dominate larger river valleys within the area.

Glacial derived windblown loess deposits mantle much of the area.

Igneous intrusions are present in the Malvern Hills area. Some contact metamorphism of coal measures has been observed with localized rank increases observed in some Canterbury coal samples, however none have been noted in the current resource area.

Generally the project area is structurally simple. Coal seams are not greatly affected by cross cutting faults. Seam dips range between 20° in the south to 50° the north of the current open pit area. In some locations it has been observed that localised slumping has caused overturning of the coal seams.

Depth of cover (DOC) varies from 0m at outcrop to over 200m at the Southeastern boundary of the model. The strike length of the deposit is in excess of 4km.
