You may have missed them but Planormix posted the minima tables at post #4 which makes it clear it is circling only.
The name of the approach already makes it clear that it is a circling approach.
VOR X 13, the suffix X means it is a circling approach (it can be any suffix: A, B, C,....)
From 2500at 10.0 DME to 1760 at 6.5 DME is a 2,1 degree slope and from 1760 at 6.5 DME to CIRCLING MDA 1120 at 4.5 DME is a 3.2 degree slope, that is no problem.
Remains the GPWS
