What are the main methods of mining? American

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.

Methods for valuating early-stage mineral projects CSA

Comparable methods allow the value estimated for a mining project to be benchmarked against mining project values established in the market. Comparable methods thus are a key tool for ensuring value estimates that are congruent with what the market would actually pay. The comparable transaction method uses the transaction price of comparable

Compare Stoping Methods of Mining

Square-set stoping is a flexible method; it can be accommodated to very irregular ore bodies, large or small, and permits following and mining offshoots of ore with minimum dilution and loss of ore. Waste can be sorted out and left in the gob. The method can be adapted where sudden changes in dip of the deposit occur and to following sinuosities or abrupt offsets along the strike or the dip
