The study aims to prepare a baseline document to develop guidelines for the SLO and develop a social licensing evaluation methodology to promote sustainable mining development. The guideline was first completed based on an extensive literature review and international examples, mainly from Australia. Then, we created a sample questionnaire using the guideline and used the questionnaire to assess the SLO of a local silver mine. The findings from this survey and the challenges associated with conducting the survey were analyzed and used to further improve upon the guideline. The survey result shows that the frequency of contact with company personnel, procedural fairness, and perceived impact on social infrastructure affect community acceptance and approval by increasing or decreasing trust in the company. Our result confirmed trust as a strong and significant predictor of acceptance and approval of the company and mining project. Our findings are similar to Moffat and Zhang (2014) and other international studies.
