Metroid Prime Origins, where is that last artifact?

So, I've been playing Metroid Prime Origins and loving it like almost everyone in the sub has been.
I decided I was going to 100% the game, and it's been a blast.

!Heck, I even found the Screw Attack the devs added to the game.!<
But where I'm having trouble is finding one last artifact, specifically The Artifact of The Warrior.
I'm aware of its location in the original Prime 1.
Find the Research Room in Phazon Mines, Power Bomb the Elite Pirate Alpha's tank to awaken him, kill him, and get your prize.
But in Prime Origins, I just can find it.
I've combed through Phazon Mines for the last hour during clean up after grabbing >!the Screw Attack!< and other artifacts.
I just wanted to ask if anyone has found it or can point me to a video on its location.
I would rather not resort to a guide so soon, but I'm stumped.
Moreover, I'm on version 1.0.4 of the game, if that helps.
