Cominco Resources is developing the US $2billion Hinda phosphate project located in The Republic of the Congo. Through its subsidiary it owns 100% of the Hinda Phosphate Project, which comprises the Hinda Permit (granted in December 2009), and the Kolatchikanou Permit (granted in June 2011). The Hinda project is the world's largest undeveloped phosphate deposit with a JORC Mineral Resource of 678 Mt and a Minable Ore Reserve of 405 Mt, sufficient for over 24 years of production. Cominco owns 100% of the Hinda and Kolatchikanou phosphate exploration licences covering 1,663 km2 of ROC’s coastal basin, upon which Cominco discovered and delineated a large graben hosted, marine sedimentary phosphate deposit between 300 m and 800 m wide, running roughly parallel to the Atlantic coast. The deposit is relatively homogeneous and thick and has a very low overburden to Ore ratio (1.5 m3:t). The Orebody is one of few that can be open pit mined, by free digging with no requirement for ripping or blasting. On 6 October 2014, Cominco applied to the Ministry of Mines and Geology for grant of an Exploitation (Mining) Licence for phosphate covering an area of 263 km2. The company's African operations are located at Rond-Point d'Avoum, Centre-Ville in Pointe Noire. ==Resource and Geology== The Republic of Congo has considerable resources of sedimentary phosphates (Apatite), dating from the Upper Cretaceous to Lower Eocene periods. The deposits form a string of outcrops that extend over 50 km along the coast inland from Pointe-Noire, and are exposed within a 750 m-wide belt – most of which falls within Cominco’s licence areas. The Hinda Phosphate Ore-boby is hosted by Upper Cretaceous (Maastrichtian) Holle Series and younger sediments situated within Cretaceous to Quaternary terrestrial to marine succession of an intra-continental rift within the Congolese Coastal Basin. Sedimentary phosphates are exposed east and north of Pointe Noire within an approximately 750m wide fault bounded belt which trends north-west and extends into Angola to the south and Gabon to the north. The belt is considered to have been preserved within a post-Palaeogene, pre-Pliocene (potentially Miocene) graben. On 4 December the company announced a JORC Compliant 531 Mt at 11.1% P0 at a 7% P0 cut-off, of which 89% is in the Measured and Indicated category. The MRE was provided by (CSA Global (UK) Ltd ). The latest MRE is based on a 5% P0 Cut-off grade. In April 2015 (SRK Consulting ) released a 2014 JORC Compliant Minable Reserve Statement. A total of 929 diamond and reverse-circulation holes have been drilled by Cominco in the Hinda deposit, for 66,231 m. Phosphate mineralisation is hosted by Upper Cretaceous to Quaternary sediments up to 65 m thick and from surface at the mine start location. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cominco Resources」の詳細全文を読む スポンサード リンク
