ARA PROJECTS

Kiri Iron Ore Project


  • The Aiyetoro-Kiri Iron Prospects are located approximately 8.7 km south–east of Aiyetoro-Kiri village on a flat topped hill. It covers an area of about 9.0 km2.
    The project site could be reached from Lokoja – Aiyetoro-Gbede paved road. From Aiyetoro-gbede to Aiyetoro-Kiri, 80% of the road is tarred
    Local Geology

    The Aiyetoro-kiri iron ore deposit forms part of the upper oolitic ironstone formation which is now preserved only at the top of the plateaux extending intermittently from Lokoja (Kogi State) to Batati/Kutigi to the north (Niger State). During the course of this surface geological mapping,three types of ironstones were encountered which are the haematitic oolitic ironstone, the lateritic ironstone and the ferruginous sandstones. These ironstone units are intimately associated.
  • The iron body is continuous all over the plateau; this iron body is about 85% hematite and 15% other iron related minerals. The overburden is less than 2m across the site
    The iron body thins out at the edges of the eastern and western parts but thick at the northern and southern edges with an average thickness of 10 and 54m respectively. This can be verified from the cross-sectional view. The geophysical survey revealed an appreciable thickness at the middle part with a span of minimum of 3.7km2; the result shows that the iron formation is more than 60m most of this points.
    The litho logy of the study area include: hematite body, kaolin, sandy clay, sandy formation and the basement complex.
    A huge iron ore potential exist on the Ayetoro-Kiri plateau. This is evidence by the discovery of large extent of the deposit all over the table land and some parts of the escarpment; as revealed by the geophysical investigation. An average thickness of the iron formation to be 45m having apparent resistivity values ranging from 39000 – 6000 ohm-m. The iron formation is underlain by appreciable thickness of kaolin deposit with an average thickness of 150m.

    The result of a survey carried out, showed that the thickness of the iron formation varies between 4-83m across the plateau with the central part being the thickest of hematite and thinning out at the edges. The investigation reveals an average value of hematite occurrence in the study area to be 45m.

     

    Infrastructures
    Close proximity of the licences to road and power infrastructure provides potential advantages in reduced capital expenditure and allows fast track project development.
    Kiri Iron ore property is located about 110kilometres north of the Itakpe government owned National Iron Ore Mining Co. Ltd. which has a dedicated standard gauge rail line that is currently under construction and at 95% completion stage
    The 254klm Itakpe-Ajaokuta-Warri rail project is expected to support the construction of the east –west lines for a better national transport system as well as improve trade for the Ajaokuta-Warri steel plants; the project was revived in November 2009 after it was stopped for 3 years over payment issues with the contractor.
    This line terminates at the delta steel plant Aladja which is located on the other side of Warri main seaport and has a harbor that can berth 2 vessel at a time with a draft of about 6.4, The harbor is currently under utilize and would be able to support the trade from Kiri.
    On Power, there is a cement plant within 50klm of the site which is connected to the national gas pipeline, this can support gas supply to the proposed mine for power generation.
