I hit him twice from the tower, but he ran off and hid, so I climbed down, sneaked up on him for another hit, then finished him off with a point blank arrow to the face as he charged me.
This... After about 20 tries, I marked him, ran for the tower and put an arrow in him. He went nuts and ran around the tower for a few minutes with me trying to pelt him with arrows (Black Panther is FAST)
After a while he ran off, fell down a nearby cliff, and got stuck halfway down.
I walked to the edge and put a few more arrows in him, he died and I carefully slid down to where he got stuck and skinned him...
Success, in about 20+ attempts, worst mission yet :(
Just shoot it from farther back. It'll run away because it can't pinpoint you. It'll usually run to the edge of the hunting area, and since it can't leave the area, it'll get stuck around the place where it hits the edge of the area. Then you just keep shooting it from a distance and it still won't be able to pinpoint you, but it'll just kind of run in circles where it has been stuck.
