S2 E78: China Embargoes Gallium. This Montana Mine Has 6x More. — Harvey Kaye, US Critical Materials

2026년 7월 23일

이 에피소드에 관해

When China restricts gallium exports, U.S. defense contractors can't rebuild the radar systems protecting thousands of miles of airspace. Harvey Kaye, Executive Chairman of US Critical Materials Corporation, explains why Sheep Creek in Montana changes that calculus.

Independently validated as North America's richest rare earth deposit — 9% total rare earth elements, gallium at 300 ppm versus the 50 ppm the U.S. was importing from China — Sheep Creek is the company's crown jewel. But the bigger story is what US Critical Materials is building around it: a full chain from mine through processing through offtake, without sending a gram to China.

Kaye explains the "rock to dock" strategy: a CRADA with Idaho National Labs, an electrochemical membrane reactor, and a full-scale processing plant going up on a U.S. Army base. He also covers the ore-agnostic integration play, AI-driven ore-to-process matching, and the timeline: 1,500 tons in 2026, commercial quantities in 2027, and an IPO targeted for fall 2026.

S2 E81: Malaysia Has 16 Million Tons of Rare Earths — 70% Is Off-Limits | Tricia Yeoh

2026년 8월 13일

Malaysia is sitting on an estimated 16.1 million tons of rare earths, but roughly 70% of it lies inside permanent forest reserves — and the country's own fragmented governance may keep it from capitalizing on the rest. Dr. Tricia Yeoh, Director of the Asian Institute for Policy and Engagement at th…

S2 E80: Why America Only Graduates 200 Mining Engineers a Year

2026년 8월 6일

The conversation about America's rare earth ambitions usually centers on ore, mines, and processing capacity. Professor Aaron Noble — department head of Mining & Minerals Engineering at Virginia Tech — argues the real ceiling is people. Aaron joins Dustin and Daniel to explain why talent is the…
