I don't think this is
mnestra. In
mnestra the reddish band is farther from the margin and usually slightly concave between the veins on its outer margin. In addition, given that this looks like a male, the absence of any conspicuous reddish area at the end of the cell is very suspect. Above all, in my experience, it just looks wrong.
That only really leaves
gorge and
pluto. From the point of view of the position, shape and extent of the reddish areas,
gorge is the number one choice. This is where trying to identify something from a single photo comes unstuck. In the field,
gorge has quite a characteristic feel - not to mention the fact you usually get a glimpse of the underside. The picture does not transmit the feel of
gorge, but rather, the feel of
pluto. The scree context you describe also fits
pluto. I agree there is too much red on the hindwing for this species, but I think that would still be where I would put my money, albeit, not much money. If you have any other pictures, even bad, humiliating, put-in-the-bin-quickly-before-anyone-else-sees-them pictures, it might help pin down the species. In the field, you can at least move your head ...
