While Antimony is certainly rare (contextually) and an earth mineral, using those terms are incorrect in the greater sense - One shouldn't confuse it (as another reply did) for a 'rare-earth metal' or rare-earth element (REE) which is a wholly different group of elements with geo-political contexts.
Antimony is a metalloid (not quite a metal) and is about as scarce as silver, tin and iodine in the Earth's crust.
