Zahi Hawass, head of the Egyptian Supreme Council of Antiquities, said the recent discovery of the pyramid remains was a rare accomplishment in the country's desert regions, the Los Angeles Times said Wednesday.
"It's common for us to find a tomb or a statue, but to find a pyramid, that is rare," Hawass said. "There are probably many more discoveries to be made around this site."
The pyramid remains were the result of 20 years of excavation efforts near the Egyptian burial site of Saqqara.
Experts have suggested the pyramid likely belonged to Queen Sesheshet, who ruled the region during the Sixth Dynasty around 2291 B.C.
The pyramid base 12 miles south of Cairo has yet to be entered by on-site archaeologists, the Times reported.
