TORONTO, Nov 24 (Reuters) - More than 80 percent of Kirkland Lake Gold shareholders have voted in favor of the mid-tier miner's takeover of Newmarket Gold, according to two sources familiar with the situation, marking the end of a contentious process.

Over 90 percent of the Newmarket shareholders who voted on the acquisition also backed Kirkland's all-stock offer, valued at about C$1 billion when announced on Sept. 29, the sources said on Thursday on condition of anonymity as the matter is confidential.
