A funerary gold mask from the Museum of Sicán, Ferrañafe, Peru was analyzed in 30 different areas using a portable equipment using energy-dispersive X-ray fluorescence. It was deduced from the measurements that the main sheet of the mask and the majority of the pendants have a similar composition and are made of tumbaga, which means a poor gold alloy enriched at the surface by depletion gilding, and have a similar ‘equivalent’ gilding thickness of about 5 µm. The nose, also on tumbaga, has different composition and a thickness of about 8 µm. The clamps are on gilded or on silvered copper. The red pigment dispersed on the surface of the mask is cinnabar.
