This assignment is to develop practical guidance and information which tax officers in mineral rich developing countries could use to control and improve mining revenues collection administration practices. It will do so by synthetizing World Bank and other relevant publications and researches on mining tax collection administration while tailoring these to the needs of tax officers working for revenue authorities to assist them with identifying potential revenue collection leakage sources for three minerals ( copper; gold; and lithium ) and measures to address these in the form of practical tools on how to assess; map risks; manage and control mineral related payments.
