The Mamutovac-1a deposit is part of the non-active exploitation field Mamutovac. The exploitation field, located in the north-western part of the Promina plateau, comprises ten bauxite deposits, several of which have already been fully exploited. The deposits occur within a relatively narrow elevation range of approximately 244–256 m a.s.l. and typically form irregular, lens-shaped bodies with lateral dimensions of up to about 100 m and an average thickness of around 4 m. Previous studies of the Mamutovac exploitation field indicate that deposit morphology is strongly controlled by the underlying paleokarst relief, resulting in uneven basal contacts and frequent occurrences of pinnacled limestone protrusions that locally penetrate and segment the ore bodies. The bauxites are predominantly of böhmitic or mixed böhmitic–gibbsite composition. However, their quality modulus generally ranges between 2 and 4, indicating relatively low ore quality, and a substantial proportion of the material has therefore been classified as off-balance ore in previous resource assessments.
