The Société des mines et fonderies de Pontgibaud (Pontgibaud Mine & Foundry Company) was a French silver and lead mining and smelting company based in Pontgibaud, Puy-de-Dôme. It mined lead-silver ore deposits that had been exploited since Roman times. Later it opened another factory in Couëron in the Loire estuary, and then closed down the Pontgibaud mines and foundry. The Pontgibaud factory in Couëron diversified into other non-ferrous metal products using imported ore. After being sold and resold it finally closed in 1988.
