If you have an LTCF-License to Carry Firearms...you Should Not and Would Not be in Violation if you carried while doing a mentor hunt....Generally speaking, an LTCF is basically used to carry to protect 1 self or themselves and others if the need arises (YES it also covers carrying while hunting for legal critters with firearm caliber used for such critters) thus, you have the laws in the Game law that has been changed...you can now carry while Spot Lighting, Bow hunting, bear hunting, Rifled Deer hunting, Flintlock hunting, early muzzleloader hunting, small game hunting, ECT...about the ONLY time you can NOT carry even with an LTCF is Waterfowl hunting (as I stated in past posts..been discussed on here before and I remember John S. Stating it had something to do with the Single Projectile issue that is not allowed while hunting waterfowl) on School Ground and in Court houses...
There ISN'T Anything in the Regulations on the LTCF laws that States you can not carry while mentor hunting!
