Summary:
The deposit consisting of the Takitimu, Coaldale and Black Diamond prospects covers an area approximately 230Ha. The deposit is bounded by the Tinker Nightcaps fault to the North East and the Fern fault to the North West. The Takitimu deposit is separated from the Coaldale and Black Diamond deposits by the Trig E fault.
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 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 production has come from seams in the Morley Formation which tend to have higher quality coal. Coal seams are faulted and folded into complex structures. Coal thickness and extent varies as seams are often lenticular and split or washed out by fluvial sand channels and syndepositional faulting and folding are indicated.
Morley coal measures of the Ohai Group have a combined vertical seam thickness which averages 4.1m however 23m thick seams have been recorded.
Coal ranks range from sub-bituminous A to high volatile bituminous C.
Beaumont coal measures of the Nightcaps Group have a combined vertical seam thickness which averages 1.4m however 7m thick seams have been recorded. Coal ranks from sub bituminous C-B rank.
The Nightcaps Group Beaumont Formation coal measures are conformably overlain by Eocene Orauea Formation mudstone.
Summary:
The Takitimu mining area has been operational since 2007, with the current Coaldale pit starting in 2012.
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.
Summary:
The ROM coal produced at Takitimu is crushed and screened on site. A process recovery of 95% is used based on a processing reconciliation study.
Product coal specifications include ash, Sulphur, moisture and calorific value.
