Yes, I read it too. As i said first, I tried to find other articles from reliable sources, causee there may be some speculation about it. Personally I doubt the GPRs can confirm there are "lot of gold and silver" behind heavy rocks. Why they said it's confirmed there is a staircase lined with a gold plate, i don't know.

They have called Jamin an "adventurer" and since the sanctuary has been plundered many times, there is litle chance to find treasures. However not impossible, as Tutankhamun tomb was in the Valley of Kings where all tombs were already plumbered too.

They are worried cause moving the stones of the wall where the frenchman says this tomb lies jeopardize the entire structure.

I do remember now the mummies of the Incas were brought to Lima around 1559, cause they were worshiped, and were lost in history. Some theories said they are beneath an old building in downtown Lima but never discovered. They said Pachacutec mummy was included there.
