In 2019, gold accounted for 93.28 per cent of gross mineral revenue while the respective share of manganese, bauxite and diamond were 6.17 per cent, 0.54 per cent and 0.01 per cent. The main methods of mining in the country are underground and open pit mining. Alluvial mining is also popular in the small-scale sector.
Open pit mining is the most common mining technology when it comes to new mines. In this technique, the soil is excavated and the mineral separation and the remaining soil material occurs on the surface. The first step in this process is the extraction of the ore (beta with high mineral grade).

Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to 'fill the gaps' on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
1. Introduction. Small-scale mining has played an increasingly important role for communities that depend on this activity worldwide. Buxton [] estimates that small-scale mining employs 20 to 30 million people in over 80 countries, and that this sector is responsible for 15 to 20% of the global production of minerals and metals.Villegas et al.[] report that small-scale mining supplies 80% of ...

The Kisenge Manganese Mine is a surface mining operation. Initial production took place in 1951. Mine operations consist of surface workings. There is one known shaft. The mining method is open pit. The ore mined is composed of spessartite, rhodonite and pyrolusite. As of 1991 there were two known tabular shaped ore bodies of unknown dimensions.
The manganese occurrence was discovered by Kunene Resources in 2013 and evaluated over a three-year period as the Olulilwa manganese project. A comprehensive exploration programme comprised of detailed surface mapping and diamond drilling was undertaken in 2016 to consider the technical and financial feasibility to mine the occurrence by open pit methods and to …
