Reference information

Comments Well-developed mineralogical zonation in district is concentric around the deposit. Preliminary fluid inclusion homogenization temperatures 217 to 434 degrees C. Location is that of Corralitos gossan (oxidized surface expression of the Tahonas porphyrycopper deposit). Exploration and evaluation for oxide copper leaching (SV Copper Company, 2008). Alteration: oxidation-argillization.
