Job Title: Biodiversity Supervisor
Company: Marampa Mines Limited
Date: 22 May 2023
Apply by: 31 May 2023



Marampa Mines Limited (MML), a subsidiary of Gerald Group, is engaged in the exploration, development, and production of high-grade iron ore concentrate, branded as Marampa Blue™, in the Port Loko District, Northern Province of Sierra Leone. MML aims to build a resilient and long-life iron ore mine in Sierra Leone and to expand operations by integrating mining, processing, infrastructure, and export logistics, alongside playing a responsible role in the economic and social stability of the region.


Founded in 1962, Gerald Group is the world’s largest employee-owned commodities trading company, focused purely on the merchanting of non-ferrous, ferrous, and precious metals, as well as related concentrates and raw materials. The Group offers its services and expertise across the entire global value chain, including sourcing, storage, logistics, finance solutions, hedging, marketing, and risk management. Headquartered in London, our foundation is in the United States; we operate trading hubs in China, the US, and Switzerland..


The Biodiversity Supervisor is a critical role within MML’s Environmental, Social and Governance (ESG) program, reporting to MML’s Environment Superintendent. The Biodiversity Supervisor will coordinate with the Environmental Monitoring team, the Sustainability & ESG Manager, and Heads of Departments across the mine site to identify, plan and implement interventions designed to mitigate the company’s impacts on biodiversity, ultimately striving for nature-positive outcomes. Biodiversity management activities are to include both short- and long-term interventions that the Biodiversity Supervisor will design and execute. MML seeks to employ Nature-based Solutions (NBSs) to the greatest extent possible. To that end, we are developing a large-scale regenerative agricultural project (led by a dedicated team). This position will create value by identifying opportunities for enhanced operations, as guided by MML’s Sustainability Policy, and ensure that the company meets its sustainability performance goals. This position will also evaluate the potential for MML to generate/certify carbon credits via a registry.

The Biodiversity Supervisor will work closely with Gerald’s US-based ESG Group. This role is functionally embedded into the Health, Safety and Environment (HSE) Department, but serves a cross-organizational purpose under the banner of ESG. In addition, the Biodiversity Supervisor will become part of the ESG MML Working Group, which works to advance sustainability projects on the mine site.


We are looking for a strong project manager with the ability to lead data collection efforts, ensure Key Performance Indicator (KPI) goals are met, foster strategic cross-organizational relationships, and contribute to the Group’s annual Sustainability Reports with exceptional writing and communication skills. By implementing international best practices in sustainable mining operations, this role will contribute to the success of Marampa Blue™. This role may require occasional travel.
