The Sakoany deposit in the Katsepy commune of the Mitsinjo District (Boeny Region, Madagascar) is an artisanal mining area world-famous for producing exceptional museum-quality celestine crystals. Discovered by a local herder and opened for systematic extraction in 1967, the site is not a conventional structured underground mine but rather a vast field of shallow hand-dug pits that remains active today with no official closure. Geologically, the deposit is hosted within a Lower Paleocene sedimentary sequence consisting of marly and sandy layers resting on fossiliferous limestones, where strontium-rich solutions precipitated outstanding blue celestine geodes.
