South Island domestic (“SID”) consists of the Takitimu mine which produces a low sulphur thermal energy coal for local agricultural, health and other food manufacturing industries. The Canterbury mine which used to be part of SID ceased operating at the end of June 2021.
2022 was another successful year for the Takitimu mine from an operations perspective. Progress was made on rehabilitating the historic overheight overburden area; this is due for completion early 2023. |

Summary:
The project is located in the Ohai Coalfield, New Zealand.
The Ohai Coalfield is a fault bounded basin containing Cretaceous sub-bituminous coal.
The defined Coal Resource is contained within the Morley and Beaumont formations.
The Cretaceous Ohai Group contains three formations – the Wairio, New Brighton and the Morley Formations.
The Eocene Nightcaps Group contains two formations – the Beaumont and Orauea Formations.
The two groups are separated by an unconformity, clearly distinguishable by micro-flora.
Most of the historical production has come from seams in the Morley Formation, which tend to contain higher quality coal. Coal seams are faulted and folded into complex structures. Coal thickness and extent varies as coal seams are often lenticular and split or washed out by fluvial sand channels and syn-depositional faulting and folding are indicated.
Morley Coal Measures of the Ohai Group have a combined vertical seam thickness which averages 4.1 m; however, 23 m thick seams have been recorded.
Beaumont Coal Measures of the Nightcaps Group have a combined vertical seam thickness which averages 1.4 m; however, 7 m thick seams have been recorded. Coal ranks from subbituminous C-B rank.
The Nightcaps Group Beaumont Formation Coal Measures are conformably overlain by Eocene Orauea Formation mudstone.
Coal rank ranges from sub-bituminous A to high-volatile bituminous C.
Several coal seams are present in two main seams in the Beaumont Formation and up to four in t ........
Summary:
The Takitimu mining area has been operational since 2007, with the current Black Diamond pit starting in 2017.
The Coaldale and Black Diamond pits are in commercial production utilising truck and excavator mining.
The Takitimu mine utilises truck and shovel for waste and coal movement. The operations are supported by additional equipment including dozers, graders, and water carts.

Reserves at June 30, 2022:
Coal resources are reported down to a seam thickness of 0.5m (one block) with an ash cut-off of 25%.
The Inferred Coal Resources have been excluded from the Reserve estimates.
Ore Reserves: a maximum ROM ash of 15% (arb) and a minimum coal thickness of 0.5m are applied.
