I don't think this pattern is chased. Chasing involves hammering from the reverse side of the metal to push out the pattern on the facing side of the metal. This does not look anything like that to me and the copper is probably too thick for that technique in any case. It could be acid etched i suppose, or simply engraved.
It is a beautiful baca-baca regardless.
