Open Pit Development | Nevada Copper Corp.

Open Pit Development The Pumpkin Hollow open pit development is approximate 4 km west of the underground mine. It includes two large deposits and areas of potential expansion both in and outside of the projected pit walls. The recent pre-feasibilty study has highlighted the potential for improved economics, simplified build and phased expansion.

Open Pit Mining - an overview | ScienceDirect Topics

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.
