Mining industry is known as a ‘high risk, high return’ business. Therefore, we understand that Due Diligence and Desk Study Practice are needed in order to minimize the future risk for the mining investors and stakeholders. Due Diligence is an investigation process on a potential mining project. While Desk Study is an evaluation activity of a mining company based on secondary data. In these sub-services, we conduct a project assessment and risk identification within technical, economical and legal aspect. Based on the result, we deliver recommendation for decision making process.
