Abia State, located in southeastern Nigeria, is blessed with abundant natural resources, including a variety of mineral deposits. Mining and quarrying have played a significant role in the economic development of the state. In this comprehensive article, we will explore the key mineral resources found in Abia State and discuss their applications and economic potential.
Overview of Abia State
Abia State was created in 1991 from the old Imo State. It has a population of about 2.9 million people and covers an area of around 6,320 square kilometres. The state is bounded by Imo State to the west, Ebonyi State to the north, Cross River State to the east, and Rivers State to the south. Abia State has three major urban centres: Umuahia, Aba, and Ohafia. Umuahia serves as the capital, while Aba is the commercial nerve centre of the state.
Abia State has a tropical climate with two major seasons: the rainy season (April–October) and the dry season (November–March). The state features mountainous and undulating terrain in the north and plains in the south. Abia State is drained by the Imo River and its tributaries. The state has substantial natural gas, crude oil, lead/zinc, limestone, and salt deposits.
Crude Oil
Nigeria is the largest oil producer in Africa, and crude oil is one of the major mineral resources found in Abia State. Oil exploration activities began in the state as far back as the 1950s. The commercial quantity of crude oil was discovered in the Uzuakoli area of Bende Local Government in 1959. Currently, Abia State has about 100 oil wells, with the Imo River and its tributaries providing access to the oil fields and hosting most of the oil facilities.
The major oil companies operating in Abia State include Shell, Agip, Chevron, Texaco, and TotalFinaElf. About 13,000 barrels of crude oil are produced in the state daily. The oil fields and flow stations are centred around Uzuakoli, Obeaku, and Umuro. The economic benefits of crude oil, such as employment, infrastructure development, and revenue generation, make it a highly valued resource in Abia State.
However, oil exploration activities have also resulted in environmental degradation in parts of the state. Constant oil spills and gas flaring pose dangers to the surrounding communities. Concerted efforts are required to mitigate the negative effects of oil production and ensure proper environmental management.
Natural Gas
Abia State is home to huge natural gas reserves estimated at over one trillion cubic feet. The major gas fields are located in Owaza, Ukwa East, and Ukwa West Local Government areas. Seismic surveys have also indicated the presence of large gas deposits in other parts of the state, including Bende, Isuikwuato, and Aba.
Natural gas is fast emerging as a key energy source worldwide. Domestically, it is used for electricity generation, heating, cooking, and as an industrial and vehicular fuel. The massive gas reserves in Abia State provide great opportunities for investors in gas exploration, production, processing, and utilisation.
Already, some companies are harnessing the gas reserves in the state. The Nigerian Gas Company has completed a natural gas processing plant at Obeaku with the capacity to process over 100 million cubic feet daily. Indigenous and international companies have also obtained licences for gas exploration in the state. Harnessing the abundant gas resources in Abia State will lead to economic growth and development through improved electricity supply and growth in the manufacturing and industrial sectors.
Lead/Zinc
Abia State is endowed with world-class lead and zinc deposits estimated at over 7 million tonnes, found mostly in the Ameka, Arufu, and Abriba areas. The lead/zinc belt cuts across 14 local government areas, including Ohafia, Bende, Item, Arochukwu, and Umuahia North.
Lead is a heavy metal used for producing batteries, chemicals, paints, solders, and ammunition. On the other hand, zinc has applications in galvanising, brass making, die casting, and the production of rubber and paints. The abundant lead and zinc reserves in Abia State hold great economic potential and opportunities for mining investors.
Currently, mining activities are carried out mostly by artisanal and small-scale miners. Large-scale mining of the mineral has not commenced. With improved infrastructure, favourable government policies, and an enabling environment, Abia State could become a major hub for lead and zinc mining and processing in Nigeria and globally. Value addition through establishing smelting plants for the lead and zinc ores mined will further enhance the benefits of the mineral sector to the state and country.
Limestone
Limestone is a key natural resource found in commercial quantities in many localities of Abia State. It is estimated that there are over 30 million tonnes of limestone deposits in the state. Limestone occurs mainly in Ndoro, Igbere, Ozuitem, and Omoba.
Limestone has a wide range of applications, making it an important industrial mineral. It is utilised in the manufacturing of cement, glass, paper, paints, chemicals, and chips used as flux in the steel industry. The huge limestone deposits in Abia State provide great scope for investors to set up cement factories that will serve both local and export markets.
Currently, there is only one notable cement factory in the state: the Benue Cement Company (BCC) factory at Alayi in Item Local Government Area. Aba and other growing urban centres in the state provide ready markets for cement and other limestone products. Increased private sector investment in limestone mining and cement manufacturing will lead to economic diversification and employment generation for the state.
Salt
Rock salt deposits have been discovered in commercial quantities in Abia State. The salt is mostly found in the Arufu and Okpuala Ngwa areas. The salt belt stretches through Isialangwa, Obingwa, and Aba North Local Governments.
Salt has diverse domestic and industrial applications. Key uses include seasoning, preserving, curing, and manufacturing soda ash, caustic soda, and chlorine. Table salt is also a widely consumed food product. Nigeria spends huge sums annually importing salt to meet demand. The salt resources in Abia State can help bridge the supply gap if fully exploited.
Currently, salt mining is done manually by local villagers around the salt lakes. Modern mining techniques need to be introduced to maximise production. Setting up small and medium-scale processing plants will also help realise the full economic potential of the salt deposits. With its proximity to the commercial city of Aba, investors stand to gain significantly from salt mining and refining in Abia State.
Other mineral resources
Besides the major minerals discussed already, Abia State also contains deposits of other valuable resources like gold, iron ore, marble, laterite, clay, kaolin, fine sand, and granite. These minerals are found mainly in small and medium-scale quantities across several localities in the state.
Gold occurs in the Igbere, Ohafia, Arochukwu, and Ozuitem areas. Iron ore deposits are located around Akpoha and Ntighauzo. Marble has been discovered in commercial quantities in the Arochukwu Local Government Area. Abia State has several clay deposits suitable for ceramics and brick making. The availability of these mineral resources provides scope for small-scale mining and mineral-based cottage industries.
Mining Opportunities in Abia State
