Hi there... This page lists 3 other experiences nearby. I have not been there myself, so cannot comment on any of them! http://www.worldreviewer.com/travel-guides/city/ouro-preto/55444/nearby/
Around have the wealth of this town comes from mining and half from tourists so yep, there are mines, and some of them for gems - in fact Oro Preto is the only place in the world where you can mine Imperial Topaz. One of the most popular sites in town is the Mineralogy Museum.
