There are many small mines scattered over a couple square kilometers of hillsides.
These mines are the only locality of a blue (copper-bearing?) variety of pectolite called "larimar". The material, formed by hydrothermally altered volcanic rocks, was (re)discovered in 1974 and used as gem/ornamental stone.
According to the Larimar Museum in Santa Domingo, the mines are currently (Jan 2023) closed for unknown reasons.
