Despite its contributions to the country's development, the mining sector in Sierra Leone has been attributed to a multitude of impacts. This study aims to explore the environmental and socio-economic impacts of mining on local livelihood. Three independent variables are used i.e. environmental, economic and socio-cultural impacts of mining. A total of 300 respondents from three communities at the Tongo field mining area are used in this current study. Moreover, confirmatory factor analysis (CFA) using AMOS version 24 was mainly used to analyze the data. The results from the structural equation model (SEM) indicate that economic benefit and socio-cultural benefits of mining activities have significantly influence the local livelihood of community members around the mining area. However, the environmental impacts of mining activities are consequential for the local livelihood of the community. Hence, the study recommends some policies to help mitigate the environmental damage.
