Cyprium Mining Corporation announced the results from additional 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 the historic Santa Eulalia, Mexico. The thirty six samples were taken from two historic stopes on level 14 of the Santo Domingo body, and averaged 30.2% Zn over an average sample width of 3.00 m. Two samples assayed less than 10% zinc and two samples were below detection levels for the zinc assay utilized, and 0 was used in the calculation of the average. If the two samples with zinc assays below detection are left out, the average is 32.0% zinc for the remaining 34 samples. Assay results for nine samples of similar zinc oxide material from a third smaller stope on the same level assayed 37% zinc. The oxide zinc material is mainly hemimorphite, a zinc silicate mineral, and contains variable but generally low concentrations of lead, iron, manganese and arsenic. Oxidized zinc material is different from the more usual zinc sulfide produced by flotation in most zinc mines and requires different processing techniques to recover the zinc metal. The results announced are part of an ongoing exploration program to evaluate the potential of known mineralized areas. Results of sampling from the Santo Domingo body taken during the due diligence period prior to the acquisition of a controlling interest in the company's Potosi joint venture, were previously announced and showed significant silver, lead and zinc values. The sample audit consisted of ten samples from level 9 and fifteen samples from level 10. The ten samples from level 9 gave a weighted average of 246 g/t Ag, 4.3% Pb and 4.3% Zn over an average sample width of 1.12 meters, while those taken by the independent third party yielded averages of 290 g/t Ag, 5.46% Pb and 3.45% Zn for the corresponding samples. The fifteen samples from level 10 yielded 78 g/t Ag, 3.3% Pb and 4.1% Zn over an average sample width of 1.16 meters, while those taken by the independent third party yielded 187 g/t Ag, 3.44% Pb and 4.31% Zn. The company does not have laboratory certificates or analytical methods for the third party samples. The 2015 underground exploration program also consisted of thirteen channel samples taken on level 6 and 11 of the mine. Three samples from level 6 gave a weighted average of 733 g/t Ag, 1.12% Pb and 0.53% Zn over an average sample width of 1.53 meters, while a sample taken from a stockpile located on level 6 yielded 376 g/t Ag, 0.75% Pb and 1.66% Zn. The nine samples from level 11 yielded 45.5 g/t Ag, 2.02% Pb and 4.10% Zn over an average sample width of 1.84 meters.
