[{"type":"text","content":"\n \n 23 October 2013 \n\n \n Conroy Gold and Natural Resources plc \n\n VIABILITY OF CLONTIBRET GOLD MINE CONFIRMED \n\n * Key Step in Bringing in a Gold Mine at Clontibret, in Co. Monaghan, \n Ireland, Successfully Concluded\n \n * Testwork Confirms the Amenability and Technical Viability of Using BIOX®\n \nTechnique to Process the Clontibret Ore\n\n * Maximum Gold Extractions Achieved on Lode and Stockwork Concentrate Samples\n After Biooxidation Were 90.4 per cent and 87.1 per cent respectively\n \nConroy Gold and Natural Resources plc (AIM: CGNR, ESM: CGNR.I), the gold mining\ncompany which has discovered a thirty mile gold district in Ireland running\nacross Counties Armagh, Monaghan and Cavan and is planning to develop its first\noperational gold mine at Clontibret in Co. Monaghan, is pleased to announce\nthat the final results of the mineralogical and metallurgical testwork\nprogramme on the ore grade material sent to Goldfields/BIOMIN confirm the\namenability and technical viability of using the BIOX® technique to process the\nore at Clontibret.\n\nThe mineralogical and metallurgical testwork, which was supervised and managed\nby independent consultants Tetra Tech was carried out on 350kg of drill core\nrepresentative of both lode and stockwork ore grade material with a 10 per cent\ndilution factor with a grade similar to that expected for run of mine.\n\nThe testwork results indicated fast oxidation kinetics, achieving over 90 per\ncent oxidation for both lode and stockwork concentrate samples. Maximum gold\nextractions achieved were 90.4 per cent and 87.1 per cent respectively with\noverall recoveries confirmed by Tetra Tech to be in line with their independent\nScoping Study.\n\nBIOX®, which is a well established bacterial oxidation technique, was\nrecommended by Tetra Tech as an appropriate technology for treating the gold\nsulphide concentrate at the proposed gold mine at Clontibret. BIOX®is an\nenvironmentally friendly proven technology with a number of plants in operation\nworldwide including South Africa, Ghana, Brazil, China and Australia. The BIOX®\nprocess gives improved rates of gold recovery at significantly lower capital\nand operating costs.\n\nThis release has been approved by Eur.Ing. Andrew J.
