Drilling Analysis and Prospecting Prediction of Ereen Gold Ore in Mandal Soum, Selenge Province, Mongolia

Abstract

The Ereen deposit lies within the North Khentei gold belt. The exploration works undertaken at Ereen have shown significant mineralization in and around the existing known vein gold mineralization. Work to date has delineated a mesothermal quartz vein system with volcanic-hosted disseminated mineralization associated with quartz-sericite carbonate and intensive silicification alteration zones. The area has approximate dimensions of 750 ï‚´650m and assay results indicate gold mineralization averaging 1.7g/t. Geophysical and geochemical data appear coincident, though drilling has shown that it is the gradient areas of the IP anomalies which appear most prospective. This has meant that some early holes did not intersect mineralization, but the more recent holes have been better targeted.
