Goat mineral would more than likely have too much copper. The llama mineral has about 200 ppm of copper; typically goat mineral is more than that. Although I have seen minerals listed for both goats and sheep and of course it has next to no copper.
We are in Canada and get ours from Agri_blend, but I think you could order yours from these folks
Sheep mineral would be better, as the copper levels should be more appropriate (or possibly absent). Or most general all-stock type minerals that don't contain copper. Most camelid folks avoid goat minerals due to the high copper content. Of course there are several companies that sell camelid specific minerals...Stillwater Minerals is one such company.
