Samaná (also known as Santa Rita) – Espíritu Santo -Río Dulce (AGA) Prospects are Porphyry-Associated and Related Gold Deposits, here several Pleistocene hypabyssal intrusives and diatreme breccias intrude the early Paleozoic low-grade metamorphic basement. The mineralization and associated hydrothermal alteration, mostly disseminated fine pyrite crystals with traces of sphalerite, chalcopyrite and molybdenite, accompanied by highly pervasive hydrothermal alteration in the diatreme breccias and the andesite hypabyssal intrusives. Dikes and stocks of dacite porphyries and polymictic breccias with pyrite traces, intrude the metamorphic rocks.
