The stock rose 17% to $11.90 in premarket trading.

Through the binding scheme-implementation deed, Harmony Australia is proposed to acquire 100% of the U.K. mining company's issued share capital for $12.25 a share, Mac said Tuesday

Mac's board recommends shareholders vote in favor of the deal, and several key shareholders have agreed to vote in favor, the company said.
