The Nigerian mining and quarrying sector recorded growth in the production of solid minerals in 2018. The total quantity of solid minerals produced rose from 45.7 million tons in 2017, to 55.9 million tons in 2018¹ – representing a 22% increase. Disaggregated by type of solid mineral, Limestone was the most produced - production grew by 95% to 27.2 million tons in 2018, and accounted for about 49% of the total tons of minerals produced. The growth witnessed in the sector may have emerged from the government’s efforts and incentives to develop the sector and also in a bid to diversify the economy. The government had offered mining companies a three to five year “tax holiday”, duty and tax-free importation of equipment, full ownership of their businesses and the ability to take profits out of the country². In addition, the government committed about $100 million intervention fund for the sector and awarded mining contracts to ten exploration and consulting firms, in 2018³. In addition to ongoing interventions, there is need to minimize the indiscriminate export of mineral commodities especially gold, tin and lead-zinc to foreign smelters, as formalizing these activities offers great potential for a significant source of revenue for Nigeria, away from oil.
