This is a Boer (not my picture). Look particularly at the head. The pendulous ears, almost flat horns, and convex profile make the Boer's head pretty distinctive. Your girl's head has none of these features.
Here's your girl again It looks to me like she has small ears that stand out from her head, a straight profile, and round horns that come vertically out of her head rather than being swept back.
I'm thinking that she looks more like a Pygmy/Alpine cross.
