The NGSA DG also noted that the marbles in the country were about 4.8bn tons in nine states.
He said, “Limestone Resources increased in tonnage to 10.6 billion in 14 states of the federation: Sokoto, Gombe, Benue, Kogi, Edo, Oyo, Ogun, Cross River, Ondo, Plateau, Bauchi, Akwa-Ibom, Enugu, and Ebonyi states.
“Estimated resources of marble now stand at 4.8 billion tons spread across nine states of the country – FCT, Nasarawa, Ondo, Edo, Oyo, Kogi, Kwara, Niger and Kebbi states.”
He also stressed the need for geological surveys and data in attracting investments in the mining sector.
He further noted that his agency was working on developing a database for other mineral commodities in the country.
Garba also said that there was a need to fully execute a geological mapping on various scales in order to assess the country’s natural endowment.
He added, “There are 337 nos. 1:100,000 geological maps in Nigeria. Only 112 nos. of such maps have been published, leaving a deficit of 225.”
Garba also disclosed that the agency was working on modernising its Geodata Centre.
He said, “The NGSA Geodata Centre is being modernised and reformed by the MINDIVER in conjunction with experts from the BGS. The centre will host over 100 years of national geoscience knowledge and data generated by NGSA, which can be easily accessed.
“Nigeria also has an estimated 2TB volume of data held in the UK and will be part of the NGSA Geodata. This will be highly essential in showcasing Nigerian mineral potential to the world.”
