Cyprium Mining Corporation announced that it has completed the rehabilitation of shaft #3 of the company's Potosi silver mine located in the historic Santa Eulalia mining district in northern Mexico. The project, which began in February 2016, consisted in the rehabilitation and improvement of the extraction capability of shaft #3 as well as improvement of infrastructure, security and preparation of prospective mining areas at levels 2 to 4 of the mine. The rehabilitation of shaft #3 will allow materials, services and equipment to be brought into the area around the shaft for near term exploration and mine development. The shaft will also allow for the removal of mineralized material from underground development at levels 2 to 4 of the mine. Shaft #3 has a mechanical daily extraction capability of one hundred tons. It must be understood however that at this time the Company has no resources or reserves at the Potosi mine and any such production would be from unmeasured mineralized material. Mineralized material extracted through shaft #3 will be processed at the Company's Aldama plant. The Aldama plant is located 42 kilometers from the Potosi mine. Under an agreement which expires in May 2019, the Company has the exclusive right to use the Aldama plant which has a capacity of 100 metric tons per day. The company is responsible for the supervision of all metallurgic processes at the Aldama plant, including quantitative chemical analysis, assaying of samples, determining feed grades and the sale of concentrates. Work at the Potosi mine in the near term will continue to focus on the area around the # 3 shaft as access is easier and rehabilitation of the hoist is now complete. Exploration using longholes with jacklegs and drifting by drilling and blasting are expected to be used to further explore these mineralized areas. To date, widely spaced sampling on levels 3-4 in the area of the Potosi #3 shaft and levels 6 and 9-11 in the area of the Potosi #1 shaft has shown that mineralized material of interesting grades is exposed at the margins old stopes and adjacent areas and this work will continue in order to evaluate the potential for defining resources. As data compilation proceeds, exploration to expand known stopes or to encounter new mineralization, possibly by diamond drilling, will be planned. Work completed by the Company at the Potosi mine has been successful in demonstrating potential for encountering mineralized material by exploration. Visible mineralization on levels 2 to 4 along with relatively easy access and near term installation of services make this area ideal to focus exploration and development activities. Construction of some underground workings will probably be necessary, but the amount of this work is not known as final survey information is not yet available. Surveying work of the old workings to provide a three dimensional framework for planning and determining the volume of material already extracted is ongoing. The sampling density will also be increased. Some of this work is already in progress in the level 4 stope and will be extended to other visibly mineralized areas surrounding Potosi shaft # 3.
