Summary:
The Thakurani operations lie in the south eastern part of the Singhbhum-Keonjhar-Bonai iron ore belt, a narrow NNE-SSW directional trending folded syncline that runs through northern Odisha, India and southern Jharkhand, India. The Precambrian horseshoe shaped belt is a well known iron ore province hosting many iron ore deposits. The enriched sequence is a traditional Banded Iron Formation that has been subject to significant weathering that has enriched the iron ore deposits. Ore is generally of the friable hematite type however more competent hematite ores and friable goethite ores are also present.
Thakurani Iron Ore Mine, located in Noamundi Iron Ore deposits forms a part of the eastern limits of the regional synclinorium. The banded iron ore formations of the Iron Ore Group cover the major part of the area. The northern slope of the area is occupied by Banded Hematite Jasper (BHJ). In the central part of the area, that is the ridge, BHJ is overlain by 5-73m thick band of hematite rock which is capped by a mantle of laterite and lateritic soil near the surface. The laterite & soil capping varies in thickness from a meter to as much as 10 meters in southern part of the area.
The iron ore of this area is mainly hematite in nature with minor quantity of goethite, siderite, specularite and limonite – the basement rock being Banded Jasper Quartzite. The ores are intercalated with chart and shale.
The Ghoraburhani – Sagasahi operations lie in the southwestern part of the S ........
Summary:
AMNS India's Thakurani iron ore mine and Ghoraburhani – Sagasahi are the production stage open pit mines in the Odisha state of India.
For the Thakurani mine, AMNS India has a permit in place for 5.5 million tonnes per annum of ore production, designated for internal consumption only. The ramp-up to a capacity of 5 million tonnes per annum was completed in 2021. The mining lease deed was executed on June 27, 2020 for a period of 50 years to June 26, 2070. Until June 27, 2021 all production from the mine had to be consumed by specified AMNS India end use plants, after which up to 25% of production may be sold to a third party. A submission approved by the Indian Bureau of Mines in late 2020 increases the permitted production rate to 7.99 million tonnes per year from 2023.
The operation and mining rights to the Ghoraburhani – Sagasahi operations were obtained through the AMNS India takeover of ESIL in December 2019. The mining lease deed was executed on March 26, 2021, for a period of 50 years and permits production of up to 7.16 million tonnes per annum of ore primarily for captive usage. AMNS India holds surface and mineral rights over 139 hectares at the Sagasahi mine.
The current mining operation at Thakurani is being carried out by conventional mining methods using excavators and trucks for ore transportation to a mobile crushing facility. The Thakurani mine is operating at full 5.5 million tonnes per annum capacity since the first quarter ........
