If you want to go cheap you can create a mineral site with a 50# bag of water softener salt. The downside is you now have a large, white, very obvious mineral site that anyone can find, at least until rain has dissolved the salt into the soil. If that doesn't matter, then that's the way to do it. The deer will eat the soil for years to the point they'll create a large pit.
I suggested Trophy Rocks because they're a whole lot less obvious, which can be important on public land.
