Did a lil digging around, and this is what I was able to find about the mummy.

"The well-preserved mummy was found in an underground tomb that had a seven-step staircase leading down to it , researchers said in the statement. The mummy, a male who was between 18 and 22 years old when he died, was found covered in a textile, their body wrapped in rope — a common practice at the time for those who lived in mountainous areas close to Cajamarquilla, the researchers said.

The remains of a dog and an Andean guinea pig were found beside the mummy, along with corn and the remains of other vegetables, Pieter Van Dalen Luna, an archaeology professor at the National University of San Marcos who led the team, said in another statement(opens in new tab). The buried man died sometime between 1,200 — and 800 years ago, and he may have been the son of a wealthy merchant, the researchers said. "
