Burial shafts were found in the area and excavation work "revealed that these shafts led to a number of corridors inside a cachette of mummies", the ministry added. His buzz was retweeted by more than 1,700 fans.
The necropolis was first detected a year ago by a team of Cairo University students using radar.
The trailer was released in December 2016.
While researchers have not yet dated the mummies, it is believed they probably lived in the Graeco-Roman period, a time span of around 600 years which followed Alexander the Great's conquest in 332 BC.
Since the dig is only in its early stages, archaeologists believe that they will find many more mummies buried in the necropolis, which is set eight yards below ground level.
The remarkable find is the first of its kind in the area, the antiquities ministry said on Saturday.
Mohamed Hamza, director of excavations for Cairo University called the discovery "important, unprecedented".
However, due to the uncertainty of the age of the 17 newly discovered mummies, some say they could also belong to the Ptolemaic Dynasty.
AFP reported the 17 mummies were not the only discovery: There were limestone and clay sarcophagi, the decorated coffins often used in ancient Egyptian burials, documents written in the ancient Egyptian script called Demotic on papyrus and gold, and animal coffins.
"Antiquities are the soft power that distinguishes Egypt", said Enany.
Egypt hopes that recent discoveries can help revive its crucial tourism sector, which was hit hard by political turmoil since the 2011 uprising.
"2017 has been a historic year for archaeological discoveries". Egyptologist Sami Gabra had last discovered the birds and animals necropolis between 1931 and 1954 in the area. However, Islamist militant attacks get in the way.
