Cyprium Mining Corporation announced the start of production at the Potosi silver mine located in the Santa Eulalia District, Chihuahua, Mexico. Production will focus initially on the Tunel mineralized body, which lies on levels 1 to 4 of the mine in the area accessed by the recently rehabilitated Potosi No. 3 shaft. The first phase of production will be to extract broken mineralized material left in stopes on levels 1 and 2 of the mine by past mining activities. Subject to receiving final explosives permits, the Company expects to begin blasting on level 4 by the end of July. The Company is also evaluating other areas for blasting on level 2 and 3. Cyprium is currently extracting twenty tons per day on a test basis and expects to achieve an extraction volume of eighty tons per day by mid- August. All mineralized material extracted from the mine will be sent to the Aldama flotation plant located 42 kilometers from the Potosi mine. The Aldama plant has a capacity of one-hundred metric tons per day and the Company has the exclusive right to use it under an agreement which expires in May 2019. The lead and zinc concentrates produced at the plant will be shipped to Trafigura Mexico under the terms of a commercial agreement with Trafigura. The Company is responsible for the supervision of all metallurgic processes, including quantitative chemical analysis, assaying of samples, determining feed grades and the sale of concentrates.
