The wolfram or \u201cblack gold\u201d was the ore explored here, used for weapons manufacturing during the first two world wars. Valued at 150 escudos per kilo in the market but came to be transacted at 1000 escudos\/kilo at smuggling prices (a small fortune at the height of the war). 3000 people worked here, and in the vicinity of Rio de Frades were opened ore than 6 km of galleries for exploration of the veins. In more numbers were those who, on their own, explored the valuable ore \u2013 the &#8220;pilhas&#8221; (looters) \u2013 and thereby won good money overnight risking, however, their lives.<\/p>\n","protected":false},"featured_media":12020,"template":"","lines_points_of_interest":[1080],"class_list":["post-15069","points_of_interest","type-points_of_interest","status-publish","has-post-thumbnail","hentry","lines_points_of_interest-line-a-arada"],"_links":{"self":[{"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/points_of_interest\/15069","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/points_of_interest"}],"about":[{"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/types\/points_of_interest"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/media\/12020"}],"wp:attachment":[{"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/media?parent=15069"}],"wp:term":[{"taxonomy":"lines_points_of_interest","embeddable":true,"href":"https:\/\/montanhasmagicas.pt\/en\/wp-json\/wp\/v2\/lines_points_of_interest?post=15069"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
