Guess where?

So which is it? I can picture ghaznavid frantically paging through the Khulu galley...

Nah sorry mate, it was the other. Good call though. I understand what made you think it was Mohlesi though, and that was part of the fun. Mohlesi has somewhat gentler and more grassy southern slopes, and doesn't have big cairns (actually barely any cairns...making it hard knowing which is the exact summit). This is kaNtuba Buttress, the lower of the two kaNtubas, but one of the very few 3300m summits which look straight down into the hills. Giants Castle is the best example of that though.

That rounded dome on the right is Wilsons Peak. Peak on the left is the summit just north of Wilsons Pass. To get that angle you may have been somewhere above the Code Eye Cave valley, or perhaps somewhere off the beaten track in the Mlambonja valley?
