I plan on adding to my existing mineral licks this weekend w/ the above mixture.. and possibly creating a few others. I had been using a commercial mix from a local source that has a strong sweet smell to it. Should I add some molasses or something to help the deer find the new licks?

I checked at Tractor Supply Company for the above items.. I found the trace mineral and the salt.. but they didn't have any pure Dical... They had several stock animal mixtures that had Dical, trace mineral, salt, ect in it.. Do I need the pure stuff or just use one of the mixtures?
Just wondering before I head to the CO-OP in the morning.
