Powerworks is an area in the floating city, SkyTown. Samus cannot access this area without the Grapple Voltage and Seeker Missile. This is also where Samus acquires the Spider Ball. The Spider ball is being contained by a metal barrier. After Grappling a gear from a suitable position and blasting it into place, the metal barrier is withdrawn and the Spider Ball is revealed, being held in the hands of a Chozo Statue wearing armor similar to Samus'. This is the only occurrence of a Chozo Statue holding an item in the entire Prime series, where this was seen often in non-Prime games.
