Sodalite is one of the typical stones used in tombstone and tile manufacturing. Namibia's mining industry is vital in supplying the dimension stone if these sodalite rocks are mined in big blocks. However, the current surface mining method employed results in the extraction of smaller blocks of about 3 cm to 45 cm due to the application of improper slope angles and use of primitive extraction tools. The study was conducted at two (2) shallow pits operated by artisanal and small-scale (ASM) miners, mining a sodalite vein in a gabbro rock formation. The study evaluated the geomechanical parameters of the rock mass through application of the Finite Differential Method (FDM) and FLAC 2D software to establish the Safety of Factor (SOF) and optimum slope angle for sodalite mining up to a depth of 120 m. The optimum overall slope angle for both pits (Oroutumba pit 02 and Oroutumba 03) is 75°while the optimum pit depths were found to be 120 m and 80 m respectively.
