Sonic drilling at Rio Tinto’s ilmenite deposit in Madagascar

QIT Madagascar Minerals (QMM)’s heavy mineral sand deposit located near the Village of Fort Dauphin, Madagascar was recently drilled using Boart Longyear Company’s Mini-Sonic drill. Continuous sand core samples were obtained to a depth of up to 30 meters for analysis and compared with the existing drilling data. Results were used as part of a validation process of the resource estimate, based on approximately 1,500 exploration holes drilled to date.
