Cyprium Mining Corporation announced the results from nine underground samples taken from an oxidized zinc body on level 14 as part of its ongoing exploration program of the Potosi silver mine located in Santa Eulalia, Mexico. The nine samples were taken from level 14 of the Santo Domingo body and averaged 37% Zn over an average sample width of 1.53m. The oxide zinc material is mainly hemimorphite, a zinc silicate mineral, and contains variable but generally low concentrations of lead, iron and manganese. Given the positive nature of these results, Cyprium has taken an additional thirty-five samples from level 14 which will be sent for analysis shortly. Oxidized zinc material is different from the more usual zinc sulfide produced by flotation in most zinc mines, including in most areas of the Potosi mine, and requires different processing techniques to recover the zinc metal. Mineralization in this area is exposed in a large chimney that extends over several levels. Although most of the mineralization on the upper levels of the Potosi mine is oxidized, local areas with preserved sulfides on the upper levels were discovered in the last few decades. The main exposures of sulfide mineralization studied to date are on levels 9 to 11, but the sulfide material also extends upward to level 6. Such sulfide orebodies were not economically exploitable prior to the advent of selective flotation in the early 1900's and were evidently left behind for this reason and later forgotten. These "perched" sulfide bodies were possibly preserved due to the vagaries of past oxidation. Assay results for samples of sulfide mineralization from Levels 6, 9, 10 and 11 on the replacement body were announced previously.
