The Ministry of Antiquities is set to announce the discovery of a number of mummies and embalming equipment at the Saqqara necropolis on Saturday.
The ministry said that the discovery includes a collection of inscribed mummification vessel measuring cups.
A communal burial shaft was also discovered where a large number of mummies were buried.
The mummies were buried in both wooden coffins and large sarcophagi, and amulets, gemstones and precious metal objects were found.
A golden mask that was discovered will be displayed along with other objects during a press conference held by the ministry on Saturday.
The discovery was made in collaboration with a German archaeological mission, close to the Pyramid of Unas.
