The stake is part of a $400 million equity raising by Lundin Gold to fund development of its Fruta del Norte gold mine in Ecuador, Newcrest said in a statement. The mine is expected to start production by end-2019.
"We see this equity investment ... as consistent with our strategy of securing exposure to high potential orebodies," Newcrest CEO Sandeep Biswas said.
The deal marks Newcrest's second foray into Ecuador after it spent $40 million to buy a 14.54 stake in London AIM-lsited miner SolGold Plc in June last year.
Newcrest said it would pay C$5.50 ($4.35) per Lundin Gold share and would be entitled to appoint two directors to Lundin's board.
Newcrest, which has reported flat production in recent years, needs new projects to grow, especially as its Indonesian Gosowong project winds down and before its Papua New Guinean Golpu project ramps up, RBC mining equity analyst Paul Hissey said in a report.
"This investment could potentially plug the gap between Gosowong ceasing in (2021) and before any production from Golpu, given ongoing delays in approvals," Hissey said.
Newcrest also said it signed a joint venture with Lundin to earn up to 50 percent direct interest in eight Ecuadorean exploration concessions by spending up to $20 million over five years.
Newcrest would manage the joint venture company and has committed to spend at least $4 million over the next two years.
"We haven't seen this sort of activity from the majors for some time probably because they have been repairing their balance sheets," said mining analyst David Lennox of Fat Prophets in Sydney.
"It's probably a sign of confidence in where the gold market is going."
