The social acceptability (SA) of mining projects is a crucial issue for the sustainable development territories and local communities. This article aims to identify issues examine factors influencing SA exploration, exploitation processing critical strategic minerals (CSMs) in Quebec. A systematic review guided by PRISMA approach was conducted, selecting 57 relevant documents after excluding several others. results reveal that between 2000 2024, publication studies on sector has increased significantly, particularly since 2013. Research mainly concentrated North America, with predominance case studies. Their analysis indicates based various issues, including need greater consideration perspectives communities, as well open inclusive communication all stakeholders. However, affected factors, demographic, economic, environmental governance, which can have positive or negative effects depending context. Following this analysis, future research should explore complex interactions these determining how some may act mediators moderators contexts through real
