Stockwork-type W-Sn mineralization in Silurian schists intruded by a Variscan biotite granite. The deposit was mined from four open pits from 1948 until 1976 as well as underground. Overall production was 335 tons of tungsten and 150 tons of tin.
Three lakes were left in the area. Remediation was carried out between 2005 and 2007.

O Complexo Mineiro de Murçós encerra um património constituído por diversas frentes de exploração a céu aberto, uma galeria mineira e por edifícios de apoio à laboração da mina e da lavaria, onde, em outros tempos, se procedeu à separação do minério. Em Murçós a atividade mineira esteve principalmente associada à exploração de volfrâmio, um metal de elevada importância para a produção de armamento durante a II Guerra Mundial. A extração de volfrâmio na região remonta ao ano de 1940, tendo sido suspensa no período entre 1976 a 1981 (in: Geopark Terras de Cavaleiros).
