[3] He participated in the excavations of many sites including the Alexandrovo Tomb, Kosmatka, Svetitzata and Starosel Cult Complex.

[5] On August 19, 2004 Kitov discovered a gold mask in a 5th-century BC burial mound outside the town of Shipka in a place he later named Golyamata Kosmatka.

On September 21 he began an excavation of the mound with 12 others, including private security guards, and soon unearthed a large bronze head.

The quality of his scholarship, his business ethics, his self-promotion and his associations with people suspected of looting and selling antiquities were issues on which he was criticized.

In February 2001, the National Archaeological Institute and Museum censured him for excavating sites without permission and took away his authorization to lead expeditions for a year.
