Alton Drilling purchased the Waihi Underground operations in October 2017.

We are currently the only mineral exploration company to own and operate designated state-of-the-art underground drill rigs. We currently employ 40+ staff to run the underground operations throughout New Zealand.

Our underground rigs are fitted with rod handlers and DCI auto drill functions. We also run electric over hydraulic and diesel operated rigs. Specialized underground light vehicles are all fitted with fire suppression equipment.
