It couldn't hurt! I used to think deer didn't really use mineral licks after mid sept but muzzleloader season started here in NC last sat and i took my wife and we had 4 deer (2 does, a cow horn, and a 6 pt) come in and both does came to the salt lick that i had down and stood there for 2-3 min each and licked on it.....Every little thing you can do to help the area is a plus......Good luck
