Technical Disclosure

The Waihi operation has been in full production since 1988 and all mine site infrastructure has been completed to support the open pit and underground operations including. The Waihi operation holds the permits, water rights, certificates, licences and agreements required to conduct its current operations. A localised failure of the north wall occurred in April 2015 which undercut the main access ramp. Operations were suspended in April 2015 and the open pit mining contract terminated in June 2015. Studies are in progress to regain access to the bottom of the pit.
