The le Puy Mine is an ancient lead Mining mine in the northwestern Massif Central , France . The mine produced mainly silver bearing galena . Geography The Le Puy Mine, in French language French Les Mines du Puy , was named after the hamlet Le Puy . It is situated roughly 4 kilometers southeast of Nontron on the right hand side of the D 707 from Nontron to Saint Pardoux la Rivi re , at an elevation of 280 meters above sealevel. The mine belongs to the commune of Nontron. Geology The mine is implanted in Neoproterozoic , fine grained paragneiss es structurally belonging to the Saint Mathieu Dome , an upwarp in the metamorphic basement rocks. The mine followed a 0.50 to 1.20 meter wide lode close to the SSE striking fault geology border fault . The vertical to steeply North dipping, mineralized lode is striking N 115 to N 120. Mineralogy The matrix of the lode consists of quartz and baryte , in some places only of baryte. The lode contains as ore minerals the sulfide s galena , sphalerite , marcasite and pyrite as well as the lead alteration mineral cerussite . Galena and sphalerite are silver bearing. The silver concentration in galena varies between 112 and 400 grams per ton, exceptionally reaching values as high as 1708 g t. The silver concentration in sphalerite is 946 g t.

Towards the very south of the Silvermine Mountains is the highest peak in the mountains, Keeper Hill or in Irish language Irish Sliabh Cime lta , which rises to 695m, dominating the area.

The earliest record of mining in the district is from 1289, but was short lived. Mining resumed in the 17th century and continued intermittently until 1874. It restarted in 1949, and shortly after a world class deposit of baryte was found and opencast mining of this began in 1963 by Magcobar Ireland Ltd. Soon after a multi million tonne orebody grading about 11 combined lead and zinc was also discovered. This was worked underground from 1968 to 1982 by Mogul of Ireland Ltd. The Magcobar mine closed in September 1992, and its extensive spoil heaps are a prominent local landmark, visible for miles.
