Shrinkage stoping is an overhand mining method that is used for self-supporting vertical ore bodies. In this method, ore is mined in horizontal slices, starting from the bottom to the top of the stope. The broken ore is left in the mined-out stope and serves as a support to the stope walls and a working platform for mining the ore above.

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.
