Thierry Jamin, who has investigated several burial sites in the North of Cusco, listened carefully the story of David Crespy. Quickly he wants to confirm the facts behind the story. Accompanied by archaeologists of the Regional Office of the Culture in Cusco, he was able to visit the site several times. His preliminary findings are unequivocal: it is indeed an entrance, blocked by the Incas at an undetermined moment of History. This one is strangely similar to a burial site, such as the ones Thierry Jamin and his companions often find in the valleys of Lacco and Chunchusmayo.

In order to confirm the existence of cavities in the basement of the building, in December 2011 Thierry and his team submit and official request to the Ministry of Culture in Lima, to perform a geophysical survey with the help of electromagnetic (EM) conductivity instruments. This license was granted a few months later.

Realized between April 9th and April 12th 2012, the electromagnetic survey not only confirmed the presence of an underground room but several! Just Behind the famous entrance, a staircase was also discovered. The two main paths seem to lead to specific chambers, including to the main squared one. The different techniques used by the French researcher(s), (Molecular Frequencies Discriminator) allowed them to highlight the presence of important archaeological material, including deposits of metal and a large quantity of gold and silver!

Thierry Jamin is now preparing the next step: the opening of the entrance sealed by the Incas more than five centuries ago. On May 22nd 2012, he officially submitted a request for authorization to the Peruvian authorities which would allow his team to proceed with the opening of the burial chambers.
