This book represents the first comprehensive publication on the development of the Guinean mining sector from 2016 to 2020. This period witnessed a record investment of $6.2 billion and implemented reforms that laid the foundations for unprecedented growth.

Through a combination of facts, events, analyses, and personal anecdotes, the author, who led the Ministry of Mines for five years and eight months, provides insights that allow readers to grasp the complexities of the industry, understand its dynamics, and envision its role in the national and international context, where Guinea is increasingly becoming a significant player.
