I've done it 6 years or so.Usually takes a week or so to heat up good in my experience.
I've personally found mineral sites to work best on whitetails and not so much on Mule Deer as far as patterning. The product I use requires 5 gallons of water to "activate" the site which would be a real chore in the backcountry if the high hunt is what you are referring to. When I'm hiked into the backcountry I'm usually focused on catching them feeding in the early am and evenings and glassing them out of the beds during the day. I'd hate to put all that beautiful country to waste staring at one area waiting for one to come to my attractant. Usually get deer on camera within a couple days of mineral site being activated. Buck Jam seems to bring in the bears which is not what I want considering I'm usually in a ground blind w/limited vision around me. Had a sow and two cubs come in once and it was just too close for comfort with her chattering her teeth and all. Good Luck!
I also feel that in my mind, and this is selfish, using bait for whatever during the high hunt takes away from appeal and the essence of the hunt. It’s a high country deer hunt in a place that a lot of folks don’t hunt. Leave the bait at home and get out your optics. Let your legs and your glass do the work. That’s coming from a guy who has had several baited trail cam sites in the past. I’m not at all opposed to baiting. It just doesn’t seem like the fitting place. Again, just me being selfish.
Here I am cutting the labels off my clothing and the handle off my toothbrush, or screw that, my teeth can make it a week, and you are thinking of hauling salt or apples. LOL
