Cyprium Mining Corporation announced the results from 71 additional underground samples taken from the Tunel body as part of its ongoing exploration program of the Potosi silver mine located in Santa Eulalia, Mexico. Of the 71 samples taken, 34 were channel samples taken at the edges of old stopes on levels 1 and 2, and 37 samples were of previously broken mineralized rock from levels 1, 2 and 3 that was left behind at the end of the last mining in this area. All samples were taken in areas where Cyprium expects initial production to take place. The 34 channel samples were taken on exposures of relatively flat lying manto and steep chimney mineralization on levels 1 and 2. Not including eight samples of oxidized mineralization from a chimney on level 2, 26 samples averaged 238g/t Ag, 5.28% lead, and 8.04% zinc over an average sample width of 1.2 m. The table below shows averages for sampling on different levels of the Tunel body, including some previously reported sampling from levels 3 and 4. All of these exposures are at the margins of historic workings near the Potosi No. 3 shaft. The shaft has been reconditioned with a haulage system capable of removing approximately 100 tons per day (1) and compressed air and water have been brought in, with an air compressor installed on Level 2. Previously broken rock, termed 'muck' or in Spanish, 'rezaga' was left behind in old stopes and mineralized material passes in several places within the Tunel body. This material has been moved down to the haulage level (level 2) to be removed from the mine via the recently rehabilitated and now operational shaft No. 3. The assays from this material average 173 g/t silver, 4.8% lead and 3.9% zinc for an average sample weight of 6.1 kg and a total of 224 kg. It is estimated that enough tonnage of this material is ready to be removed from the mine to conduct the initial extraction tests, ahead of the Company's expected explosive permit grant. The results announced are part of an ongoing exploration program to evaluate the potential of known mineralization in the Tunel body near the Potosi No. 3 shaft. This shaft has been rehabilitated and provides access for services such as compressed air and for haulage of broken mineralized rock from the Tunel body on levels 2 to 4 where underground exploration and development will begin shortly. Work is also in progress for the Santo Domingo body, also known as Main Silicate body, which was also partly mined in the past at levels 9 to 11. Efforts are underway to determine the volume and grades of remaining material in this area, which is not accessed by the Potosi No. 3 shaft. Past production from the Santo Domingo body was from the Potosi No. 1 and Potosi No. 5 shafts and from a shaft on neighboring ground controlled by a third-party. Plans for gaining access to the Santo Domingo body are currently in consideration. Mineralization in the area where the samples were taken 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 (2). 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. The Santa Eulalia District: Santa Eulalia is a world class polymetallic mining district located in the central part of the State of Chihuahua, Mexico, approximately twenty-two kilometers east of the City of Chihuahua. Mineralization in the area was originally discovered during the Spanish colonial period in the 1500's, and recorded production has occurred over more than 300 years. Santa Eulalia ranks as one of Mexico's primary silver and base metal producing districts with nearly 450 million ounces of silver and substantial amounts of lead and zinc mined. Mineralization occurs in an area about 10 km in length and 5 km in width. Production and reserves for the district have been estimated to be about 50 million metric tons (3) with grades of 125-350 g/t Ag, 2-8% Pb and 3-12% Zn (3) (4), along with appreciable quantities of tin and vanadium. The Santa Eulalia district covers approximately forty-eight square kilometers and is divided into three areas, the West Camp, the Central Camp and the East Camp. The Potosi silver mine is located in the West Camp. The West Camp has produced most of the minerals from the district from an area 4 km long in a north-south direction and 2 km wide in an east-west direction, with the Potosi silver mine being one of the primary producers.
