There is no bone, just meat. The joint has been frozen and is defrosting, that's what the White is.Goat and lamb can be cooked about the same. I have done goat shanks a few times and I like them better than lamb shanks. Goat is a little sweeter. I have never smoked or cooked a goat rump joint. It looks like mostly bone. Is that true? If it's mostly bone, smoke it and make the smoked goat into a stew. Let us know when you decide.
