The Takitimu 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 8.2m; however, 23m thick seams have been recorded.Beaumont Coal Measures of the Nightcaps Group have a combined vertical seam thickness which averages 0.5m; however, 7m 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.DimensionsSeveral coal seams are present in two main seams in the Beaumont Formation and up to four in the Morley Formation. The total combined coal thickness varies from less than 1m thick up to 25m locally.The model covers an area 2.4km in width by 3.6km in length.The deposit resource consists of the Black Diamond pit which covers an area approximately 80Ha.The deposit is bounded by the Nightcaps Fault to the northeast and the Fern Fault to the northwest.
