Sessions & Presentations
Panel
Aligning Public & Private Capital at Scale: Financing the Next Generation of Critical Minerals Projects
As global competition for critical minerals intensifies, the ability to align public and private capital at scale has become a defining factor in whether projects move from concept to production. This discussion will focus on the real-world mechanisms enabling that alignment—from blended finance structures and loan guarantees to offtake agreements and strategic co-investment models. What works and what doesn't work.
Panel
Financing the “Mine-to-Magnet” Value Chain
Explore how capital can be deployed more effectively across extraction, refining, separation, alloy production, and magnet manufacturing. Discussion will focus on closing funding gaps across the midstream and downstream sectors, reducing project risk, and aligning public and private investment to support long-term supply chain resilience. Panelists will examine evolving financing models, strategic partnerships, government incentives, and opportunities for vertical integration that can help scale North America’s critical minerals and rare earth magnet industries.
