[5] Other firms such as Falconbridge Ltd., Inco, Argosy Minerals and QNI however are still active in New Caledonia, particularly Inco in the Goro mine which produces both nickel and cobalt, about 54,000 tonnes of nickel annually. The nickel concentration is inhomogeneous and also varies with the depth. These crusts dredged from the flanks of New Caledonia's main island, Grande Terre, . After an introductory chapter and a review of the published geodynamic models of evolution of the SW Pacific, Chapters 3-5 focus on the main geological assemblages of Grande Terre: the pre-Late Cretaceous basement terranes, the Late Cretaceous to Eocene cover, and the Eocene Subduction-Obduction Complex, one of the largest and best-preserved in the world. It is distributed in lateritic layers that cover about one third of the area of the main island of New Caledonia. [6], Strip mining is the most common technique adopted for nickel mining and statistics show that stripping of 500 million tonnes of overburden had to be removed to extract nickel ore, which amounted to clearing an area of 20 hectares (49 acres) per million tonne (five million tonnes of ore per year generate 25 million tonnes of tailings). Located in the South of New Caledonia it employs 1350 workers. CARTHA project (regolith mapping by airborne hyperspectral remote sensing) (with CNRT and IRD, 2011). New Caledonia is an island of the south-western Pacific Ocean which belongs to France. Total Inferred Mineral Resources now stand at 8.5 million tonnes at a grade of 3.17 g/t. The editors and authors are to be congratulated on such a large undertaking, particularly the senior editor who has co-authored all the chapters. For a long time, the nickel industry was of no benefit to them. Correspondingly, the mined area decreased from 21,500 to 8,700 hectares (53,000 to 21,000 acres) and the number of people employed in the industry from about 6,200 to about 3,600. The knowledge in the geological reference base is of great importance to the economy and society. Mineral resources have always been important to the economy of New Caledonia. Nickel, cobalt, iron, and also gold, copper, coal and jade were exploited at several sites. Chapters 9 and 10 provide a comprehensive review of New Caledonias mineral resources. Since its inception in 2007, CNRT has funded some 50 multidisciplinary research projects. Many river delta areas have been affected creating changes in aquatic flora and fauna; the mining effluents are reported to have affected about 40 streams in their middle and lower reaches. Koniambo Nickel SAS (KNS) failed to reach its full production capacity in 2019 and theSocit Le Nickel (SLN) continues its transformation, expanding its ore export business and adjusting its work organisation in order to gain efficiency.

La Socit Le Nickel was founded in 1880, it became a wholly-owned subsidiary of a new parent company called Eramet-SLN in 1985, now the Eramet group. Abstract The main metallic mineral resources of New Caledonia are hosted by the obducted Peridotite Nappe. main mineral resource in new caledonia nickel-new the pacific islands were attractive to europeans in the early 1800s because of what economic activity livestock!!! Because of low nickel content in the ore, local smelting resulted in vast amount of displaced rocks near the smelters that changed the local landscape.[6]. New Caledonia Natural resources. Opencast extraction to depths of 5060 m is being employed (the shallower layers have no commercial value). While it does endeavour to develop fundamental and applied research projects, it also strives to provide technical and economic solutions and foster knowledge-transfer between mining companies and other businesses and professionals in the industry.
