A famous locality that has produced tons of magnificent celestine specimens. It is located near the village of Sakoany, on the western side of the banks of the Betsiboka River (where it empties into the Bombetoka Bay), at the northwestern coast of Madagascar. It is further located about 12 km south of Katsepy, the nearest administrative centre.
The celestine-bearing layer is found in a maximum 30 m thick lens between layers of crinoidal limestones and sandy greywacke of the Danien period (Paleocene, 65 million years old). The celestine occurs mainly as 2 different types: as geodes in varying sizes [Ratsimabazafy (1973) reported a geode about 60 cm in diameter and weighing 54 kg], and as crystal clusters up to 15 cm in diameter. The yearly production is about 15 tons (Pezzotta 1999).
The celestine was first discovered in 1967 and the diggings first started close to the seashore. Later they moved some hundreds of meters away to a higher level (+ 15 m). The locality consists of numerous small, irregular, up to 15 m deep holes in the ground.
