At MML, you make the difference

Work with us

Your participation in our journey is key to unlocking MML’s success in building a reliant and sustainable iron ore project in Sierra Leone. At MML, we work as one big team. We have many departments and functions, but our goal is one. We are focused on making Marampa Mines, the Sierra Leone leader in sustainability, and our Marampa Blue TM 65% Fe iron ore product a recognised brand in the iron ore sector.

MML believes that a diverse team allows us to foster better workplace skills, talent, team-working and knowledge sharing, bringing broader views and leading to better decision-making and a culture of continuous improvement. We are making an effort to increase the overall participation rate of women in our workforce, which in 2022 increased to 18%. Our goal is to reach 30% in the medium-term.

Opportunities to work with us are published in local centres around the mine, national newspapers and on our website and social media. Due to the number of applications received, only short-listed applicants are contacted regarding interviews.
