There is provided a material categorisation and transportation system including a plurality of mine vehicles for transporting material within a mine site from a first location in the form of a blast site to a second location. The system includes a sensing device for actively sensing chemical property characteristics of raw blasted mined material such that the raw material can be categorised into a plurality of material categories based on the sensed characteristics. The system further includes a loading device located at blast site for loading the raw material into a predefined one of the mine vehicles based on material category for transportation to the second location. The system is such that each of the mine vehicles only carries raw material of a predetermined one of the material categories.
