I haven't found a link to these news in English, which were published yesterday on El Mercurio, the oldest Chilean newspaper.
Around 800 titles -some Silents among them- have been recovered by the Cineteca of the Universidad de Chile, including the first nitrate copy of one the best known of Chilean Silents "El Húsar de la Muerte
" (The Hussar of Death) (1925). Many other rare films have been found including the only extant copy of Jean Epstein's "The Mongol Lion
" (Le Lion des Mogols) (1924) which stars Ivan Mosjoukine.
I am not really sure about this film being really lost until now, since there's a review of it at us.imdb.com written in 2007, which I know isn't anything to trust.
Here's the link to the story in case anyone interested can read in Spanish:http://tinyurl.com/m8fp2e
