Greaves, a furniture maker from Shropshire, had travelled to the country on February 20 to visit friends and was last seen alive two days before he was due to turn 29 on April 7 while undertaking a solo trek from the village of Pisac.
The furniture maker was expected to return home on 10 April.
Peruvian authorities were assisted by his relatives and friends who searched the region near to the village with a helicopter and drones, reports BBC News.
As well as help from the British Embassy, a fundraising page had also been set up to aid the investigation raising £31,000.
