The coal mining industry plays a crucial role in global energy production, and the need for accurate and updated information about coal deposits is essential for effective resource management. This study focused on the re-evaluation of the Morupule Coal Mine block 2 (MCM2) that was initially evaluated over 50 years ago. The aim was to utilise the change in methodologies and advancement in technology over the years, leading to more accurate and reliable results. By re-evaluating the MCM2 coal block and incorporating the advancements in methodologies and technology, this study provided an updated understanding of the coal deposit focusing on the Morupule main coal seams’ potential and feasibility for future mining. Findings rendered the project both technically and financially feasible at the current economic condition based on the estimated coal resource and cost estimates, respectively. The overall in-place coal resources of the Morupule main seam were estimated to be 812 million tonnes (Mt). This resource was further broken down as 715 Mt Measured Resource and 97 Mt Indicated Resource. Mining method anticipated is open cast mining using a dragline in combination with drill and blast techniques, roll-over mining where progressive rehabilitation is conducted as mining takes place. The proposed opencast mine has a production capacity of 3 million tonnes per annum, requiring capital investment ofUS$57 million and targeting a coal selling price of US$100 per tonne, with a potential net present value of US$1.094 billion.
