Major Mines & Projects Otjikoto Mine

The mining operations use conventional open pit mining methods and equipment. Mining is based on a phased approach with stockpiling to bring high-grade forward and provide operational flexibility. Ten geotechnical domains have been defined in two oxidation domains (calcrete and oxidized; fresh rock), and pit slope angles vary by geotechnical

Open-Pit Mining Methods

2017-4-9  Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit

8.2.3.1 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.
