Sorry it took so long to reply. I found this information at FIAF (International Federation of Film Archives):
FUNDACION CHILENA DE LAS IMAGENES EN MOVIMIENTO
Clemente Fabres 814 C , Providencia Santiago C.P. 6641376 , CHILE
T: 56-2 225 4039
F: 56-2 269 1469

I don't think they are very well funded -- they don't appear to have a website. However, if you go to the FIAF
website there is further contact information available.
