I lump this kind of film in with Peplum generally, otherwise you end up with multiple categories like Capa e Spada, Jungle Films, Pirates, Russia, Mongols, Vikings, or even Salgarien - which is what this is, since it's based on a novel by the prolific Emilio Salgari
It's available on DVD as SANDOK LA MONTAGNA DI LUCE from Flamingo Video/Cecchi-Gori in Italy. And despite what the box says (1.85:1 anamorfico), it is in fact a full 2.35:1 anamorphic picture:

Picture of a dancing girl for a change - the lovely Luciana Gilli.
Soundtrack is Italian only, but with Italian subtitles, which I find helps.
You don't happen to have an English Language VHS do you ?
