The Mount Edwards Nickel Project lies predominantly within the Coolgardie Domain on the western margin of the Kalgoorlie Terrane in the Norseman-Wiluna Greenstone Belt of the Archaean Yilgarn Craton, Western Australia.The characteristic stratigraphy of the Kalgoorlie Terrane consists of a lower basalt unit overlain by komatiite, which is in turn overlain by an upper basalt unit. This mafic-ultramafic succession, referred to as the Coolgardie Group, is overlain by a unit of felsic volcanic and sedimentary rocks, the Black Flag Group that is found to the east of the Project area. The stratigraphic sequence within the Coolgardie Domain is inferred to be a continuation of the Kambalda stratigraphy.The greenstone sequence has been subdivided into six (6) stratigraphic units. Four (4) phases of deformation have been recognised in the Widgiemooltha mining district and surrounding areas comprised of an early phase of D1 recumbent folding and thrusting followed by a transpressional regime with large scale, upright open folding (D2), sinistral, strikeslip D3 faulting (with associated enechelon folds) and prolonged ENE to WSW regional shortening (D4).The area also hosts significant felsic intrusive units containing lithium mineralisation throughout the Coolgardie Greenstone Domain.Widgie TownsiteThe WTS orebody dips on average at 75o to the east and plunges to the south. The deposit has mineable horizontal widths between 5m to 20m with ore predominantly being disseminated nickel sulphide. The primary nickel sulphide orebody starts on average at 80m below the surface (320mRL) extending to 520m below the surface.The deposit consists of two (2) mineable lenses both striking north-south with strike lengths up to 300m.The main lens mostly sits between 10m to 20m off the basalt ultramafic contact with the minor southern lens being all in ultramafic.Gillett and Widgie 3The Gillett orebody dips on average at 85o to the west and extends over a total strike length of 1450m. The deposit has minable horizontal widths between 3m to 15m with most ore being disseminated nickel sulphide. The minable primary nickel sulphide orebody starts on average at 150m below the surface (350mRL) extending to 420m below the surface. The orebody is open at depth and along strike in both directions.The deposit consists of two (2) mineable lenses both striking north-south with on average, 15m between the lenses. The main lens mostly sits between 10m to 20m off the basalt ultramafic contact with the minor western lens at times on the basalt contact.The Widgie 3 orebody has a near vertical dip and extends over a total strike length of 320m. The deposit has mineable horizontal widths between 3m to 12m with most ore being matrix and disseminated nickel sulphide. The mineable primary nickel sulphide orebody starts on average at 60m below the surface 330mRL extending to 420m below the surface. The orebody remains open at depth.The deposit consists of a single mineable lens located on the basalt ultramafic contact.ArmstrongThe Armstrong Orebody dips at an average of 55o to the south-west with minable horizontal widths between 1.5m to 25m. The orebody starts at the base of the Armstrong open pit 230mRL (105m below the surface) and terminates at depth at the 0mRL (335m below the surface). The Armstrong orebody plunges to the north and extends over a total strike length of 250m.The deposit consists of a single mineable lens striking north-west to south-east. The main lens mostly sits on the basalt ultramafic contact with a felsic dyke and some large faults intersecting the north end of the orebody. The orebody terminates at depth being intersected by a large granite intrusion.132NThe 132N orebody dips on average near vertical with mineable horizontal widths between 2m to 10m. The orebody starts at the base of the 132N open pit 300mRL (80m below the surface) and extends at depth to the 50mRL (330m below the surface). The 132N orebody plunges to the north and extends over a total strike length of 220m.The deposit consists of multiple mineable lenses striking north-south. The main lens mostly sits on the basalt ultramafic contact with some sections of high-grade channel structures in the basalt. The orebody is open at depth and may continue down the plunge angle of the mineralised ultramafic syncline.
