It’s not about Greenland (Ad)

The petrodollar arrangement that anchored the US dollar for 50 years quietly expired in June 2024. Since then, China has cut its Treasury holdings by 45% from their peak, and BRICS nations offloaded $47 billion of American debt in a single month. The Trump administration has responded with a $12 billion critical minerals stockpile called Project Vault, equity stakes in miners like MP Materials and Lithium Americas, and a push to secure resources from Greenland to Ukraine. Porter Stansberry lays out the full story in a new documentary, including five companies positioned at the chokepoints of what he calls Trump's New Dollar.tc pixel

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
