30 lost burials archaeologists are still searching for

Statue of Akhenaten (Reigned c. 1351-1334 BC). 18th Dynasty. One of a series of colossal statues that once lined a colonnade in the Precinct of the Aten at Karnak.

The burials of famous people provide enduring archaeological mysteries, but they're mainly of symbolic value. 

Many archaeological discoveries do come from ancient burials but usually not those of the famous. For example, they can yield information about the society of the buried people, their role in it or the technologies associated with their grave goods. And modern scientific tests on human remains can reveal details of the deceased's sex, ethnicity, family connections and diets.
