Gold Mine Expansion

Surface water strategy supporting a staged mine expansion, where site drainage and containment had to keep pace with an evolving pit and waste-landform footprint.

Settling ponds, culverts and surface drainage were redesigned in step with each stage of the expansion — the site's water infrastructure had to keep pace with a footprint that kept changing under it.

Catchment behaviour was re-modelled at each expansion stage so approvals conditions stayed current with the site as it changed, rather than lagging behind construction.
