The ore reserve estimate is based on the utilization of ore sorting pre concentration from operating year 3 onwards. Mine design and scheduling have been organized to ensure the technical and financial viability of the project. The ore reserve is the economically mineable part of the mineral resource at the time of reporting and contains ...
17 years Navidad Project in Argentina is the worlds largest undeveloped silver deposit. Currently, Chubuts Law 5001 prohibits open pit mining and the use of cyanide in mineral processing in the entire province. Law 5001 banning open pit mining methods would need to be changed, or rezoning enacted, before permits for ...
Mineral Processing. The mined ore is crushed and milled before the flotation process to desired grain size. Crushing is done in two phases followed by milling in the bar and ball mills. The flotation process is conducted in the stages. The first stage is the silver gold lead flotation which is followed by the zinc silver flotation and pyrite ...

Mine and mine operations. Mining is done dominantly from the underground mine but a small open pit has been planned to access the ore body near the surface. Taivalhopea Joint Venture mined 2 570 meters long decline from surface to a depth of 350 meters and 2,2 meter diameter vertical ventilation shaft extending to ca. 330 meters depth from surface.
Project, and in August 2015 EIA Positive Decision was received from the Ministry of Environment and Urbanization for construction and operation of the Lapseki Gold and Silver Mine and Processing Plant Project In addition and as part of EIA, the following studies have been performed for the Project Study Area;
The Bayhorse mine has two existing accessible rehabilitated adits where mineralized material is being extracted. With a maiden resource comprised of 292,300 short tons at an average grade of 21.65 troy ounces per ton silver for total contained silver of 6,328,400 ounces.
Mining and mineral processing (mining of silver. 1. *. 2. * Mining is the extraction of valuable minerals or other geological materials from the earth from an ore body, lode, vein, seam, reef or placer deposits which forms the mineralized package of economic interest to the miner.
