Barricks gold output fell from 2 million ounces to 719000 (Ad)

Barrick's gold production has plunged from 2 million ounces to just 719,000, leaving the world's second-largest miner running on fumes. Newmont's $15 billion purchase of Newcrest, the largest mining deal in history, still couldn't keep output growing, proof that majors must keep buying to survive. With record cash flows and shrinking mines, gold majors are positioned to launch a wave of acquisitions targeting the best junior assets.tc pixel
