Work will begin immediately and the report is expected to be completed within three to four months.
Azarga brought in Tetra Tech late last year to review the data associated with the maiden resource estimate announced last year.
As a result, Azarga reckons there is a strong chance that a PEA performed using existing data will indicate robust economics for Unkur.
"I remain very confident that further exploration at Unkur will significantly increase the size of the resource," said Dusty Nicol, Azarga's president and chief executive.
"Our target for the next round of physical exploration is a doubling of the resource tonnage with an enhancement of overall copper and silver grades.
“Our expectation is that the outcome of this PEA will result in our current resource at Unkur demonstrating positive economics.
"The project will then only benefit from additional exploration success."
In addition, Azarga said it had continued to advance engaging with a number of potential strategic partners at both the Unkur project.
It is also embarking on a re-interpretation of the results of the 2016-2017 exploration program to refine plans for upcoming physical exploration works.
The resource group is also reviewing potentially attractive acquisitions in the broader Chara-Aldan region within which Unkur is situated.
