Cast fake. 100% certain. Sorry. The casting seam is plain as day, and the pores are casting bubbles - not the type of prosity from spending 2000 years in the ground.
Casting bubbles produce pearls, not pores, and I see no obvious pearls.

they can produce both. Pearls are from bubble in the mold, if one is pours. Like with plaster. Pores are from air being captured in the metal pour itself, or from left over wax in the mold.
Anyway, it has a clear casting seam.
