The gold mask was retrieved from an open grave buried in Barangay San Antonio, Oton, Iloilo dating from the late 14th or early 15th century.

The mask is a gold nose-disc and eye mask that covers the facial orifices of the dead.  It is a burial custom of the Southern Chinese and practiced by a limited group of Filipinos that persisted through the Spanish Era.

The original gold mask, considered a national treasure, is kept at the National Museum in Manila.  A replica of the mask and skull was donated by the Museum and is displayed at the Oton Tourism Office.
