At the end of this analysis focused on the problem of the new mining legislation in the Democratic Republic of Congo, it was a question of summarizing the evolution of the mining sector and the problems faced by investors in the said sector, which is the bearer of economic growth and development of the country and contributes to a major part of the national budget.It is no less true that the investment code provides an incentive framework for direct investments favourable to nationals and foreigners, but the new mining legislation is still a work in progress and a brake on the development of the mining industry in the Democratic Republic of Congo. In the course of the application of this law, scientific studies, views of NGOs in the natural resources sector and other claims have decried a mining regime that is not equitable, that is more favourable and generous to mining companies, while the State and the population derive only residual income from the exploitation of the country's natural resources.
