The National Environmental Policy Act (NEPA) permitting process commenced in March 2016 and led by the United States Forest Service. A draft Environmental Impact Study is expected to be released in May 2019.
Resolution will be the deepest block cave (~2km deep) and one of the hottest underground mines in the world (76° to 82° Celsius). This will be achieved by extending an existing shaft, developed for the historic Magma mine, from its current depth of 1.5km to 2.1km depth. This is a highly complex and challenging mining activity due to space restriction, potential excessive groundwater and poor ventilation. This work is expected to commence in CY2019.
The Project is aligned with the BHP strategy of large, long-life, low cost, expandable assets.
