"(Coming from Plougasnou). From Morlaix to Saint-Jean-du-Doigt, take the road called Prajou and then a path to the sea at Beg. In the rocky coastal cliffs, there is arsenopyrite, chalcopyrite, covellite, galena, goethite, hematite, magnetite, marcasite, pyrite, and quartz. Pyrrhotite and rutile crystals are much rarer. Apart from these minerals and depending on the locations, one can also collect cobaltite (particularly at Krec'h-Meur)." [Belot, 1978]
