Chadormalu deposit has some 400 million tons of resource and 320 million tons of reserves split between northern and southern ore bodies with average Fe-and P-Content of 55.2% respectively 0.9%.
The Commercial Reserve according to Long term Mine Planning is 360 Mio ton.
With consideration of 10% Mining Losses the Minable Ore is estimated to be approximately 320 Mio tons.
The deposit has three main components, Magnetite, Hematite and Apatite which its phosphorous act as disturbed element, based on ratio of Hematite to Magnetite the iron ore body has been divided into oxidized and non-oxidized parts.
The Oxidized part consists mostly of Magnetite.
Some 300 Million tons of resource is oxidized and 100 million tons of resource is non-oxidized.
The mining operation would be scheduled 12 million tons annual ore feed to beneficiation plant and around 1 million ton annual lump ore (high Fe content and low phosphorous) production.
To follow this schedule there are needed to exploit around 30 million tons ore and waste per year.
The Beneficiation Plant at the time being comprise four Lines but the fifth line is in under construction.
