Cyprium Mining Corporation announced the results from its initial phase of exploration at the Potosi silver mine located in Santa Eulalia, Mexico. The underground exploration program consisted of thirty-four channel samples and had as its primary objective to audit past exploration results from over five hundred samples taken in 2014 on levels 9 and 10 of the mine by an independent third-party. The audit sampling included taking twenty-five duplicate samples of the 2014 program.

Sampling in new areas was also conducted on levels 3 and 4 of the mine where initial pilot production is planned. Nine samples were taken in this area. 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.

In general the sample results from Cyprium were similar to the 2014 samples that were taken in the sample place; however, the sampling by the Company was done in a more systematic method with more continuous channel sampling that done by the third party. It was observed that many of the previous channels were incomplete or were taken outside of the channel marked on the walls or back of the workings. Also, samplers that aided the third party program stated that some samples were taken from broken rock or muck on the floor of the workings and not from in-place mineralization.

The sampling on levels 3 and 4 of the Potosi mine was completed in workings where initial pilot production is planned. Seven samples from level 4 yielded average values of 578 g/t Ag, 4.99% Pb and 2.8% Zn over an average sample width of 1.65 meters, and two samples from level 3 yielded averages of 100 g/t Ag, 2.79% Pb and 8.43% Zn over 1.45 meters. The sampling was widely spaced and more systematic sampling will be needed to determine the expected grades of the pilot mining program.

The samples were placed in labeled bags secured with plastic tie strips and were delivered directly to the analytical facility for analysis, ALS Chemex de Mexico, located in Chihuahua City, Mexico. The samples were weighed, identified and photographed prior to sample preparation. All samples were analyzed in Vancouver by the ME-MS41 method for 51 elements, and over limits for Ag, Pb and Zn were reanalyzed by the Me-OG62 method when Ag is greater than 100g/t and Pb or Zn are greater than 1%.

ALS Chemex is an internationally recognized analytical laboratory.
