The actual spawn /loc is 1240, -450, the listed location (-1240) has the wrong sign.
However, the static boar at that location is not a PH. This spawn has a different mechanic than the other rares in the zone as people have said before. It spawns as "an event" triggered by killing roaming mobs in the north section of the mines. I stubbornly assumed reports of this nature were anecdotal for too long.
After killing the static spawn in that corner many, many times, I finally acquiesced and began killing roaming mobs nearby. Almost immediately, the burdened bloodtusk spawned and started roaming westward. It was not at the correct time to have been from the static spawn in the corner (less than 5 minutes after I killed that one).
