DIABAROU BOTTLE ROLL ASSAYS RETURN UP TO 280g/t GOLD Summary  Bottle roll, cyanide leach assays from Diabarou drill holes (previously reported by fire assay technique on 1 April 2016) enhance high grade results by an average of 60%. Significant intersections now reported as:  6 metres at 53.77g/t gold from 36 metres, including 2 metres at 153.50g/t gold  3 metres at 110.30g/t gold from 120 metres, including 1 metre at 280.00g/t gold  28 metres at 3.90g/t gold from 88 metres, including and 9 metres at 8.36g/t gold  21 metres at 2.00g/t gold from 45 metres, including 2 metres at 7.63g/t gold  The high grade results support visual observations of coarse or nuggety gold logged in numerous holes  Planning commenced for follow-up drilling at Diabarou to assess the open pit resource potential  RC drilling (5 holes for 760 metres) completed at the Solona North-West prospect within the Yanfolila Project with results expected in late April
