Hmm.. maybe SLAVE/MOUNTAIN OF THE CANNIBAL GOD (1978). Stacey Keach and Ursula Andress were in it. Probably what you're looking for is one of the famed Euro cannibal movies.
it looks good , but sad to say it isn't the one i am searching for, i don't know wich decade it was made (think the 90's) and i believe it had something to do with archaeology
