Be Care : this entry is the same as "Roua Mines, Gorges de Daluis, Guillaumes, Alpes Maritimes, France". You can see this one for more informations.
Does this need to be merged? (I am not familiar with this area, but have heard of the Roua mine.)
Peter Haas already commented on this problem in the Managers' Forum:
"There is at least an inconsistency in that the local language name doesn't display the same hierarchy levels, i.e. "Puget-Théniers" vs. "Guillaumes"."

C'est le secteur du Dôme de Barrot. Il y a ces deux liens :
http://www.pays-de-guillaumes.com/frameset/index.htm
http://asnatnic.club.fr/secgeo.htm
Il y a aussi un livre non cité, je crois : Les anciennes mines de cuivre du Dôme de Barrot (Alpes Maritimes) par G. Mari, éditions Serre, 1992
Ce secteur du Dôme de Barrot comprend :
- Les indices de la Clue de Roua (une quinzaine de petites galeries) qui semblent être appelés "mines de Roua")
- Gîte du Pont des Roberts
- L'indice de Tireboeuf
- Le gîte de Bancairon
- Indice de la faille de Canté
- Indices du vallon de Berthéou
- Le gîte de l'Hubac de Jourdan avec plusieurs indices
- Gîte de Léouvé
- Indices du Raton
- Indices de Liouc, de la Cime de Serraye, du Col de Roua, de la Tête de Giordanet, de la Crête de Forné
- Gîte de Villaron-La Nouguière
- Gîte du Cerisier
Bien amicalement.

Yes.

effectivement la clue de roua et les mines de roua ne sont qu'un seul et même endroit, par chez nous on parle des "mines de roua" pour désigner l'ensemble des mines, et la "clue de roua" est un torrent à proximité immédiate du groupe de galeries nord bien connu des amateurs de rafting du coin, par contre les descriptions ne sont pas identiques.
Serge ta liste n'est pas mal mais il me semble que Léouvé, Le Cerisier, Villaron et Raton ne sont pas dans la zone de Roua, mais plutôt de Puget Thenier (autre bassin versant).
Par contre il est vrai qu'il manque de la doc, notamment quelques articles dans riviera scientifique, ou plus simplement "Mines et Minéraux des A.M." par G.Mari !
Il est à noter que les mines (si si avec des galeries) de l'Hubac de Jourdan et de Bancaïron ont été "sécurisées" à l'aide de ... dynamite, peut être pour éviter qu'un loup ne s'y casse une dent !...

Sorry!
I am glad to grasp this opportunity to reset a truth: the true inventor of this mineralogical occurrence was not Gilbert Mari in the 90's (and not me in the 70's) but Jean VERNET, whose grandgrandfather was this engineer Victor Juge. Jean Vernet was a great climber as well as a geologist full of energy and HE re-discovered all these small galleries in 1952-1955.
Later on, the link was done by him and a few other scientists in BRGM (among whom the famous Paul PICOT in BRGM and Paul SAINFELD in the mineralogical gallery of Paris school of Mines) that the old samples of native copper exhibited in this museum and being 15 to 25 cm x10 cm in size) came from these mines as well (they were a gift from Victor Juge).
These specimen were then cut in polished sections whilst Vernet gathered new specimen from the mines. Alltogether were then identified the algodonite, domeykite, koutekite, silver, gold and electrum in this deposit, making it a very original mineralogical locality for France, already. It was in 1965 !!
It is a pity that these early discoverers are generally forgotten by the new authors, who really deserve to be proud to have discovered the new arseniates, but they forget too quickly that the very original sulphides of the deposit (despite not NEW species) were discovered by these scientists 25 years before them.
Regards
Jean Feraud (BRGM)
