The coal deposit at Maiganga is recently being exploited for power generation. In order to assess its quality and ascertain its rank, aproximate analysis was conducted by this study. The result of the analysis shows that the coal deposit has low calorific value, high percentage of ash, inherent moisture, and volatile matter. Relatively, there is decrease in absolute density, more organic matter, and rich in water, oxygen, and hydrogen. It was therefore established that the coal falls within the lignite rank. Inherently, the Maiganga lignite comes with various implications which include; limited use, generation of huge waste (ash), low thermal value, easy accessibility and availability, and susceptibility to weathering.

Keywords: Coal deposit, proximate analysis, Maiganga, Lignite, Rank, Implications.
