Sunrise Diamonds secures prospecting licence for barite in Ireland
25 November 2009
AIM listed mining group Sunrise Diamonds has been granted a prospecting licence for base metals, barite, silver, gold and platinum group elements near Bantry, County Cork, in the south-west of Ireland.
The company is targeting the Derryginagh barite deposit for the production of high-value white "paint-grade" barite for use as mineral filler in paints and plastics. White paint-grade barite is the highest-value use for barite having significant sales volumes. Off-white barite is used as a lower value mineral filler and high volumes of low-grade barite are used as a weighting agent in drilling mud in the oil and gas industry.
The Derryginagh mine was worked in the period 1864-1922, supplying white barite to the local paint industry. In the 1970s the mine workings were de-watered and mapped by a local company and in the 1980s four inclined holes were drilled to intersect the barite vein at 100 meters below surface.
Sunrise is now planning to collect samples of the barite mineralisation for metallurgical characterisation and quality testing before undertaking further drilling and economic evaluation.
The Derryginagh barite project is the second new project recently announced by the Sunrise as it seeks to broaden its geographical base and widen its commodity interests which, until recently, have been focused on diamond exploration in Finland.
