Canyon Resources Limited announced that the Environmental and Social Impact Assessment (ESIA) for the Minim Martap Bauxite Project (the Project) was submitted on 1 June 2021 to the Ministry of Mines, Industry and Technological Development (MINMIDT). ESS (Environmental and Social Sustainability), an Africa-based advisory services firm focused on Health, Safety, Environment and Communities (HSEC) management, managed the development of the ESIA on behalf of, and in collaboration with, Canyon. The ESIA is a critical component of the mining permit application process and has being undertaken in line with national legislation, the International Finance Corporation (IFC) Performance Standards and other key international standards, frameworks and guidelines. The scope of the ESIA covers the three exploration tenements (Minim Martap, Makan and Ngaoundal), and includes the haul route between the mine and the inland rail facility at Makor, the rail line itself between Makor and Douala, infrastructure at the port of Douala, as well as the transhipment route and deep water anchorage location. National Cameroonian consultancy Rainbow Environment Consult and international consultancy Golder Associates were selected to support ESS with the ESIA. Baseline studies were undertaken covering physico- chemical, biodiversity and socio-economic parameters. Public consultations were undertaken with communities and other stakeholders to provide feedback and to contribute to the development of socio- culturally appropriate management measures. Key impacts that the ESIA addresses through aspect specific socio-environmental management plans (SEMP) include land acquisition and compensation, air quality, noise, water resources and limited biodiversity impacts. The ESIA contains a fully costed management plan for how the Project will mitigate each impact, including with regard to mine closure and rehabilitation. The costs are consistent with those forecasted in the Pre-Feasibility Study (PFS)1. Canyon recognises that HSEC management requires a long-term engagement, and the impact of COVID-19 has meant that a phased approach to addressing identified impacts has been adopted. As is usual for a project of this magnitude, further targeted studies and management planning will be undertaken as part of identified mitigation measures.
