One of the richest emerald mines in Madagascar. It is located 30 km S of the town of Mananjary and 8 km south of Irondro in the Mananjary district in the Eastern part of Madagascar. It is the largest mine in the southern zone of the Mananjary emerald district. From 1993 to 1990 it produced several thousand kgs of emerald of different sizes and quality.

The emerald mineralisation occurs within phlogopitite developed at the contact between pegmatite and basic/ultrabasic rocks, characterised by pegmatites intruding highly folded and boudinaged amphibolites.
