Abstract	The Quesigua epithermal occurrence is formed for quartz veins with base metals and gold, and it is hosted in cretaceous volcanic rocks from Teneme formation. Crystalline quartz textures, base metal rich and adularia-sericite host rock alteration are the principal features. The results of paragenetic, fluid inclusions, and sulfur stable isotope studies indicate an deep epithermal low-sulfidation or intermediate sulfidation origin. d 34 S data suggest a magmatic provenance for pyrite, sphalerite and galena. In addition, salinities are low (2,57-9,86 wt % NaCl equiv.) and the formation temperatures are around 230-270 oC. The emplacement occurs at 350-600 meters beneath the paleo-surface. Quesigua occurrence is the first low sulphidation epithermal system documented in Moa-Baracoa region. It shows that epithermal mineralization style may be found in deeply eroded volcanic arches.
