Not buying it. Cut and paste from:
Hoax? Three Fingered Nazca Mummy
Suspicion of a modern fake comes in part from the people involved:
Jaime Maussan is a UFOologist - a journalist
well known in UFO circles as someone who hypes evidence-free claims of aliens, etc. He appears to be the person who led Gaia to the mummy.
Jay Weidner of Gaia has a long history of making esoteric videos like "
chemtrails and the sun", and does not seems like a neutral documentray filmmaker. He holds some quite strong unscientific beliefs, like:
the physical manifestation of the soul leaving the body.
Dr Jose de Jesus Zalce Benitez has worked with Maussan before, most famously with "Roswell Slides", where he performed extensive analysis of a photo that he said was of a non-human body at Roswell, but which
turned out to be a mummified child on a museum shelf in South America. So he does not have a very good track record.
M.K Jessie appears to be a real radiologist but really gives very little information other than saying that based on the small images she has been given she think it's unlikely to be a modified human skeleton.
Natalia Zaloznaja (probably better transliterated as Natalya Zaloznaya, ) - the supposed "head of image analysis" may well be a real doctor, but does not say anything of note.
So simply based on the track record of the people involved, I would have to put "fake" as the most likely explanation in the absence of additional independent evidence.
Where are the mainstream archaeologists and geneticists? One can run a genetics test quickly, easily, and cheaply these days.
