MONTREAL , Aug. 22, 2016 /CNW Telbec/ – Cyprium Mining (TSXV:CUG) is pleased to announce 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 .

MONTREAL , Aug. 22, 2016 /CNW Telbec/ – Cyprium Mining (TSXV:CUG) is pleased to announce 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 as previously announced (see News Release of June 20 , 2016).  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 today are part of an ongoing exploration program to evaluate the potential of known mineralized areas.

Mr. Alain Lambert , Chairman and CEO of Cyprium commented: “The three areas where we are currently focusing our exploration efforts inside the mine are the Tunel body at level 2 to 4, the oxide zinc body on level 14 and the sulfide mineralization in the Santo Domingo body, also known as Main Silicate body. The Santo Domingo body, which was partly mined in the past on levels 6, 9, 10 and 11, assumes top priority in terms of evaluation and preparations for exploitation.”

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 (see News Releases of August 12th and September 3rd, 2015) as summarized in the table below.

The primary objective of the 2015 exploration program at level 9 and 10 was to audit past exploration results from over five hundred samples taken in 2014 by an independent third-party. The audit sampling included taking twenty-five duplicate samples of the 2014 program.

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.

The Santo Domingo body is not accessed by the recently rehabilitated Potosi No. 3 shaft that will be used to provide services such as compressed air and for haulage of broken mineralized rock from Tunel body on levels 2-4 (see News Releases of June 9 and Jun13, 2016) where underground exploration and development has begun.  Past production from the Santo Domingo body was from the Potosi No. 1 and Potosi No. 5 shafts and from the Buena Tierra shaft on neighboring ground controlled by Grupo Mexico. Proposals for gaining shaft access to the Santo Domingo body are currently in consideration.
