5 History of mining in the Maramarua Coal field
Previous mining activities:
The coal deposit was first discovered in 1869
- Small scale underground mining took place between 1871 – 1914
- Glencoal purchased the United Coal Company and began mining of the Kopako open cut mines in 1946
- Coal Corporation and Glencoal joined forces to develop the Kopako 1 and 2 open pits to supply coal to the Meremere power station in 1958.
- Meremere power station was closed in 1991 and the Kopako 1 and 2 pits were allowed to flood
6 History of mining in the Maramarua Coal field
Mine Redevelopment:
- Dewatering of the Kopako pits commenced in 2008 by Solid Energy
- Coal was successfully trialed to potential customers in 2011/2012
- Construction of current mine commenced late 2014
- As part of the liquidation of Solid Energy in 2017, the Maramarua mine and its assets were sold to BT Mining Ltd.
