Out of these sugyas , it comes out we apply Rov by a metzieah. However what about a case which the item found is 100% not the Jews. IE: I'm walking through Sqvaretown where the populace is 99.9% Jew and 6 goyim who take care of things. I find on the floor a beautiful gold neclace with a cross on it; in a case like this would we also say to go after Rov and I have to announce this cross or not?
Thank you very much!

You definitely don't have to announce it, as there is no question it is an Aveidas Akum (see CM 266:1).
