Barite is the mineral form of barium sulphate.\n \nFollowing the grant of an exploration licence at Derryginagh, in November last year, the Company has moved quickly to evaluate the commercial potential of the project. The initial testwork was carried out by SGS Mineral Services in Cornwall on two vein barite samples hand picked from the surface waste dumps. The tests included a simple gravity separation test which produced a very high-grade barite concentrate that exceeds the required chemical specification for the purest and highest value white filler grades of barite. Colour testing, carried out by an existing buyer of filler grade barite, was also favourable.\n \nThe next stage of work will be to access the dry upper levels of the old mine workings to collect larger representative samples for more detailed testwork. It is intended that the results of this further testwork will allow for the design of a low cost plant for ...
