Bayelsa State, located in the Niger Delta region of Nigeria, is endowed with abundant solid mineral resources that provide extensive mining prospects. This article explores the diverse mining opportunities across various minerals present in different parts of Bayelsa State.
Overview of Bayelsa State Geology and Mineral Deposits
Bayelsa State has rich sedimentary geology spanning three major basins: Benin, the Niger Delta, and Anambra. This geology produces extensive deposits of various minerals like limestone, gypsum, glass sand, phosphates, granite, laterite, crude oil, and natural gas.
The State Mineral Resources Map outlines the types, estimates, and locations of key minerals across different areas in Bayelsa’s eight local government areas. These mineral assets provide Bayelsa with exceptional mining potential.
Limestone Mining
Limestone deposits in Bayelsa are concentrated in Yenagoa, Ogbia, Nembe, and Brass LGAs. Significant limestone reserves estimated at over 300 million metric tonnes provide ample opportunities for mining and processing.
Limestone Mining Locations
- Agudama-Ekpetiama – Enormous, high-quality deposits and proximity to Calabar port and the Koluama gas plant make this an ideal location for large-scale limestone mining and export. Reserves are about 200 million metric tonnes.
- Ayama-Oporoma: Estimated reserves here exceed 60 million metric tonnes. Comparative proximity to markets in Rivers State and the Port Harcourt area creates export opportunities.
- Other deposits: sizeable limestone deposits available for small-scale mining exist in locations like Okordia-zarama, Igebiri, Minibie, Gbarain-Ekpetiama, and Tombia-Ekpetiama.
Limestone Mining Investments
Setting up limestone mining and processing operations in Bayelsa can supply raw materials for major industries and yield good returns. These include:
- Cement Plants: Large-scale cement factories are in huge construction demand in Nigeria and West Africa.
- Steel Plants: Limestone and gypsum are needed for steel manufacturing.
- Agricultural Industry: Ground limestone is used as a soil conditioner and neutralizer.
- Construction: used for building and road construction.
- Manufacturing: Used in several industries, from paints to pharmaceuticals.
Gypsum Mining
Gypsum deposits have been discovered in commercial quantities at Akeredolu in Brass LGA. Reserves are estimated at over 3 million metric tonnes. Further deposits are also indicated in Ekeremor, Southern Ijaw, and Ogbia LGAs.
Gypsum Investment Opportunities
Gypsum mining and manufacturing plants for value-added gypsum products present attractive returns given market demand.
- Cement production: being a critical additive in cement
- Plasterboards are used in building interiors and exteriors.
- Fertiliser imparts sulphur and calcium. Corrects soil alkalinity.
- Paints provide a finish and sheen.
- False ceiling: for decorative and functional needs
Glass sand mining
High-grade silica glass sand deposits have been identified in parts of Kolokuma Opokuma LGA, with reserves of over 7.5 million metric tonnes. Further substantial reserves are indicated across Southern Ijaw LGA.
Glass Sand Applications
- Glass manufacturing: for making various glass products, from flat glass to glassware.
- Ceramics are used in the manufacturing of tiles, sanitaryware, tableware, etc.
- Paints provide sheen and binding action by microfine silica particles.
- Foundry: used for making moulds and cores.
- Chemicals: raw materials for silicon metal, sodium silicate, silicon carbide, etc.
Phosphate Mining
Significant phosphate deposits have been confirmed in locations around Amabulou, Ekeremor LGA. Studies indicate reserves over 18 million metric tonnes, highlighting the potential for commercial exploitation.
Phosphate Uses
- Fertiliser is a critical ingredient in fertiliser production. Improves crop yields.
- Food industry: used as a preservative, flavour modifier, and baking agent. Improves water retention.
- Metal treatment: Phosphating imparts corrosion protection to steel and metal parts.
- Animal feeds provide phosphorus and calcium for healthy animal growth.
- Flame retardants
Granite Mining
Granite deposits occur in areas like Akipelai and Sagbama LGA, as well as extensive reserves in Kolokuma Opokuma LGA with an estimated 80 million metric tonnes. Kolokuma granite is similar to popular African Coffee Brown granite.
Granite Applications and Investment Potential
The attractive Kolokuma granite presents opportunities in:
- Dimension Stone Industry: polished slabs and tiles for interiors and exteriors Growing local and export markets.
- Ornamental stone: monuments, headstones, sculptures, etc.
- Construction aggregate: granite sand, granite dust, and crush for concreting.
Crude oil and natural gas
Bayelsa is a major oil- and gas-producing state. This provides well-established opportunities for international and indigenous companies in:
- Exploration
- Production
- Services: seismic, drilling, construction, etc.
But new marginal fields provide openings for smaller investors.
Other Minerals
In addition, Bayelsa has occurrences and deposits of other minerals like:
- Bentonite Clay: Applications in Drilling, Foundry, Paints, etc.
- Lignite is low-grade coal for energy.
- Salt is used in the chlor-alkali process.
- Marble: building and decorative stone
- Laterite and Gravel: Construction and Infrastructure
Enabling Mining Investment in Bayelsa
To fully leverage its mineral endowment and attract investors, strategic steps are needed:
- Updated geological mapping and confirmation of reserves.
- Streamline licencing and approvals.
- Offer tax incentives and exemptions.
- Facilitate land access and community cooperation.
- Develop transportation infrastructure for evacuation.
- Ensure security in exploration areas.
- Promote PPP projects.
Conclusion
In summary, Bayelsa State offers extensive and diverse opportunities for mining different mineral resources across limestone, gypsum, glass sand, phosphates, granite, and energy resources. Small- to large-scale investments in quarrying and processing these minerals promise good returns given market demand. However, updating geoscience data, facilitating access, and improving infrastructure are vital to attract investment and fully unlock Bayelsa’s mining potential. These opportunities can drive state industrialization, export revenues, job creation, and overall economic development.
