The mineralization is distributed between eight supergiant and a significant number of other smaller deposits. During the last hundred years approximately 80 mines have been operating. In total they produced ~ 300 million tons of polymetallic ores (Pb, Zn, Cu, Au, Ag, Sn), although sulfur and copper have been the main commodities processed in most cases.<\/p>\n<div id=\"attachment_474\" style=\"width: 310px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore.jpg\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-474\" class=\"size-medium wp-image-474\" src=\"http:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore-300x199.jpg\" alt=\"No more for ore\" width=\"300\" height=\"199\" srcset=\"https:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore-300x199.jpg 300w, https:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore-1024x679.jpg 1024w, https:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore-226x150.jpg 226w, https:\/\/sga.cuni.cz\/wp-content\/uploads\/2015\/11\/no-more-for-ore-150x99.jpg 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-474\" class=\"wp-caption-text\">no more for ore<\/p><\/div>\n<p style=\"text-align: justify;\">The main attraction of this field-trip was <span style=\"text-decoration: underline;\">the underground visit of the active mine Neves-Corvo (SOMINCOR&nbsp;<\/span><span style=\"text-decoration: underline;\">company) \u2013 Cu-Sn-Zn ores<\/span>.
