I'm kind of confused, you want a mineral site, or do you want bait?
I use mineral sites to help out the does that are nursing fawns in the spring and summer, as well as to get trail cam pics of bucks growing their head gear.. Usually a home made mixture, sometimes specific products. If I were you I'd go the cheap route, home-brew. I usually just freshen existing ones.. but the one below is a brand new one, a few weeks old. Once the rain dissolves it all in the surrounding area, they'll continue to hit it hard, often times even digging it out 8-12 inches deep.
