Square-Enix Help with Gilgamesh

i need help with fighting Gilgamesh in final fantasy 12, the first time i fought him, i one and he jumped off the bridge. i dont know where to find him after wards! anyone know?

 

I remember that you kill him inside that mine in Bujherba or something like that.
Try going there.

 

i did, thats the first place you fight him in, the Lhushu mines, but then, he jumps off the mine's bridge and after that, i look for him through out all the mine but he's gone.

 

Go to phon coast using the crystal and head north east. Look for the shiney object near the man to get the site 11 key and go back to Lhusu mines and go to the place which need they key and use it and the rest you will figure out. The Gilgamesh fights were the funnest, funniest and best fights in FFXII

 

where is the location that i need to use the site 11 key? i already got it.
oh and in ff12: revenant wings for the ds, the gilgamesh fight is super funny cuz Vaan said that he was lost and Gilgamesh got all nerveous and a bit pissed.
