There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Safety and environmental control of mining activity remain key drivers, but expectations of sustainable development require the provision of electricity, water, healthcare and education to the local communities where mining operations are based. Companies are also more exposed to Political Risks and K&R activity than had previously been the case.
