Arune5 Eish, looks like that got dropped or it got stuck under something heavy. Looks to be a bit deeper than superficial in the first pic. I'd also be a lot nervous about re-stringing it too.
Definitely fixable though - headstock repairs like this are far too common, usually from falling off guitar stands (particularly epiphone's and gibson). I'd guesstimate R1-1.5k for the repair.
If in the Cpt area, Traut Guitarworx, if in Jhb, JD customs have both done loads of these repairs - they should be able to give you a better idea of damage & cost.
Hope she's playable again soon!
