%X Manganese oxides are of interest as, among a number of other applications, supercapacitor materials for energy storage systems. Nsutite, a naturally occurring Manganese Oxide was studied as a possible high-volume source of materials for supercapacitor applications. X-ray diffraction and thermal analysis (DSC/TGA) measurements were carried out to characterize its physical properties, and Cyclic Voltametry and galvanostatic charge-discharge measurements were carried out to obtain its electrochemical properties. The XRD and thermal results support transitions of nsutite, upon heating which were attributed to conversion to MnO<sub>2</sub>, and to Mn<sub>2</sub>O<sub>3</sub> and eventually to Mn<sub>3</sub>O<sub>4</sub>. The electrochemical results of the as mined material show supercapacitance behaviour, suggesting that nsutite, with some heat processing, is to be a promising high-volume source of manganese oxides for supercapacitor applications.
