Gold Fields shareholders are starting to better understand the miner’s proposed acquisition of Yamana Gold, CEO Chris Griffith said on Friday as he tries to win investors over to the deal that was negatively received by the market.

Gold Fields has had “constructive” and “tough” discussions with Redwheel, a shareholder that publicly called for the miner to scrap the deal, as part of its engagements with investors, Griffith told reporters.
