Hmmm.
I don't understand mounting TV high. Best watching TV position is when
viewed little lower than eye level.

I'd use a 6' flex drill bit.
Heat is the biggest destroyer of modern electronics. Thats why they
put large heat sinks and fans in things like tv sets, computers, etc.
Even a small fireplace will pump the heat into that tv, and will
greatly shorten the life of the tv, as well as possibly warping
plastic on the case or even the screen. What you want to do is just
plain stupid. You have other walls to use, put it ANYWHERE ELSE. NOT
above the fireplace.
After you find another place for the tv, look up "wiremold" on the
internet or go to an electrical supply house to buy some. It comes in
plastic or metal, use what suits your fancy.
You could pull a Cask of Amontillado: " 'For the love of God, Montresor!'
" 'Yes,' I said, 'for the love of God!...'
"I forced the last stone into its position; I plastered it up. Against the
new masonry I re-erected the old rampart of bones. For the half of a century
no mortal has disturbed them. In pace requiescat!"
Don't know if this will get you all the away but:
In my game room I (carefully) removed the base board and cut a notch at
floor level. Run the cable and a power line through the notch and up
into a stud bay with the cable and power outlets behind the wall mounted
TV. Re-install the base board and your done.

If your house/chimney is like mine, the chimney is boxed in with
framing on the exterior of the house with plenty of room around the
chimney. I also have a basement. Drill from the inside drywall into
the cavity that surrounds your metal chimney. Be VERY careful not to
drill into the chimney. Access the cavity by removing siding and
cutting thru OSB a large enough panel to get to the wires that will
protude thru the wall. Make this access panel away from the street
side if possible. Install outlet with squeeze box. Run wires down
cavity into basement and then to the place that will house all other
equipment and electric. Replace panel/siding on chimney cavity. Hook
it all up and you're good to go.
