Mine de Margnac, Compreignac, Haute-Vienne, Limousin, France
Closed in 1995. Episyenite type deposit. Located near Margnac, 2.5 km ENE of Compreignac and around 5 km SW of Razès.
"On the D5 between Compreignac [https://www.mindat.org/loc-25349.html] and la Crouzille [https://www.mindat.org/loc-1719.html] there are several mines and there are also unexploited deposits with autunite, hematite, beautiful feldspars, muscovite, quartz, and uraninite." [Belot, 1978]
Note: Belot probably means one or more of the Compreignac sublocalities, see https://www.mindat.org/loc-25349.html
