Why Mineralogy and Heavy Rare Earths Define the Western Supply Chain

In this episode we chat to Don Swartz, CEO and President of Rare Earths Americas, a company advancing a portfolio of rare earth projects across Brazil and the United States.

We discuss the recent discoveries and heavy rare earth potential at Homer-A, the scale and development plans for Alpha in Brazil, and the emerging Foothills Rare Earths District in Georgia.

Don also gives us his perspective on why mineralogy matters more than headline grade, the challenges of building a Western rare earth supply chain, and why critical minerals represent a decades-long industrial challenge that the West is now trying to solve in just a few years.

KEY TAKEAWAYS

Deposit style and metallurgy matter far more than headline grades, as conventional flowsheets like ionic clays and monazite deliver saleable concentrates at a fraction of the capital expenditure of bespoke hard-rock projects.

While light rare earth processing has expanded, the Western supply chain faces an acute shortage of heavy rare earths such as dysprosium and terbium, driving significant ex-China price premiums.

Benefiting from advanced mining frameworks, clean hydroelectric power, and rich ionic clay deposits, Brazil is poised to become the premier global hub for rare earth production outside Asia.

Revitalising the Western critical minerals industry is fundamentally constrained by a shortage of technical talent and mining engineering expertise rather than just access to capital.

BEST MOMENTS

"I always say that you should watch how explorers vote, because it's usually with drill rigs." 

"If you fast forward to 5, 10, 15 years from now, Brazil will undoubtedly be the epicenter of ex-China, ex-Southeast Asia rare earth production." 

"There's a lot of processors now that have moved, but what the West has not solved is where the heavies will come from."
