I think the boldore is a bug/error, a pokemon that is not supposed to be in there (not even recorded on pokedex). I got mine to lvl 100 still nothing happened...
Dawn stone can be bought at the market in Hagane City (the first city after you left your hometown).
Sun stone can be mined at Hanatsu Mine. Fennekin, unless you choose it as starter, you can only get it in post-game either from sukiro sensei or ryo royal samurai.
the first lucky egg is given...
