Environmental Issues and the Prospects of Mining in Nigeria

without efficient data infrastructure to gauge the viability of the vast deposits of precious metals precisely from gold exploitation only, it has been estimated that Nigeria loses $50 billion year after year (Omoh, 2016). Lost in all these is the danger of overlooking the

Late-orogenic gold deposits in the north-eastern part of ...

The known gold deposits are mainly represented by gold-quartz veins with sulfide mineralization. Gold-quartz veins cross the various rocks of the Precambrian basement, which forms part of the ArabianNubian mountain massif. - Since most known gold deposits are confined to quartz veins, historically researchers have focused on this type of deposits.
