The Guldberg - Waage chemical equilibration method was applied to calculate the ionic content of the hydrothermal fluid that has precipitated Ag-Au-Te ores with milky and clear quartz in a stockwork of veins at Panormos - Liardades Bay. The Au-Ag-Te mineralization is developed in nine (I to IX) successive stages with Base Metals Tellurides, Native precious metals and a supergene stage at the end. The metallic and non-metallic ions content of the hydrothermal fluid was calculated for temperatures between 300°C and 190°C. Reconstruction of the evolution of pHysicochemical conditions in the fluid within the same temperature interval yielded calculated values of ΣΟ= IO"1 to 10°, a=10'29 to 109 2 and 1= 0.4
