Brunswick Group is handling South Africa’s Gold Fields Ltd. as it inks a $6.7B agreement to acquire Canada’s Yanama Gold Inc. to create the world’s No. 4 gold mining company.

The offer of 0.6 Gold Field shares for each share of Yamana stock represents a 33.8 percent premium to the 10-day trading average.

Chris Griffith, CEO of Gold Fields, says the transaction will unite two companies with complementary portfolios, cultures and strategic priorities. “The result is a combination with much greater capacity and potential value than the sum of its parts,” he said.

Newmont, Barrick and Agnico are the top three gold mining companies. AngloGold Ashanti drops to the No. 5 slot following completion of the Gold Fields/Yamana deal.

Gold Fields has mines in South Africa, Ghana, Peru, Chile and Australia. Yamana’s holdings are in Canada. Yamana’s operations are in Canada and Chile.

Brunswick has Timothy Schultz (Johannesburg); Pip Green, Nick Bias and Tom Pigott (London); and Emily Levin and Nikki Ritchie (Washington) handling media for Gold Fields.

Yamana relies on FTI Consulting’s Sara Powell and Ben Brewerton (London) for its PR work.
