Care & Maintenance and Site Services

Year: 2012–Present
Client: Newmont Mining Corporation and TMAC Resources Inc.
Project Scope Performed Under: Nuna Contracting Ltd. & Nuna West Mining Ltd.

 

In 2012, Newmont Mining Corporation placed the Hope Bay Project on care and maintenance while seeking a buyer. In March 2013, TMAC Resources Inc. assumed ownership of Hope Bay. During the transition and into present day, Nuna (through its company Nuna West Mining Ltd.) remained on site, providing a full range of site services for TMAC’s exploration and environmental programs. Initial work involved the continued care and maintenance of existing facilities and small infrastructure projects such as jetty repairs and reclamation at Patch Lake.

Following the receipt of full project funding in 2015, Nuna was authorized to complete additional major infrastructure work to support TMAC’s Path to Production, including development of the mill pad and foundations, quarry development, airstrip and apron expansion, extension of the Tail Lake access road, and construction of the South Dam. The South Dam will provide containment for the tailings generated by the process plant. Phase 1 of the dam will be completed by summer 2018, with plans to raise the dam in 2020.

Nuna continues to provide site service support and ore processing assistance, as well as the excavation and recovery of ore from a surface trench mine.
