SEOUL (Reuters) - Korea Zinc's new share sale plan announced on Oct 30 has been suspended due to a revision request by the South Korean financial regulator, a regulatory filing said on Wednesday.

This means the overall schedule related to the share sale may be changed, and if the company failed to submit a revised share sale plan within three months, it will be considered withdrawn, the filing said.

Shares in Korea Zinc were trading down 4.6% shortly after the filing, erasing earlier gains.
