Open Pit Mining . Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

Open cast mining is the removal of rocks or sediments that contains minerals, with economically important elements. The advantages of open cast mining: • More cost effective, than shaft mining. • The working conditions are safe for miners, there is no risk of toxic gases or cave ins. • Trucks and mining machinery can move around freely.

These will be unique to the sequence of the open pit underground interaction, which can take any combination of the following forms: Scenario 1 – Open pit transitioning to underground; concurrent mining. Scenario 2 – Underground mining below existing open pit. Scenario 3 – Open pit mining through existing underground working.
