Steve Schoffstall
Managing Partner & Head of ETFs | Sprott Asset Management | Critical Materials and Rare Earths ETFs
"Head of Sprott's U.S. ETF platform; launched REXC, the first U.S. ETF focused purely on rare earths companies outside China."
Biography
Steve Schoffstall is Managing Partner at Sprott Inc. and Head of ETFs at Sprott Asset Management USA, the U.S. fund arm of the metals-and-mining asset manager. His relevance to resource investors is direct: he decides which mining and critical materials ETFs Sprott builds, and in April 2026 his team launched the Sprott Rare Earths Ex-China ETF (REXC) — the only U.S.-listed ETF with focused, pure-play exposure to rare earths companies and no Chinese securities.
Schoffstall has spent close to two decades in the ETF industry. He started in the portfolio management group at ProShare Advisors, helping launch the firm's first ETFs and serving as commodities portfolio manager. He then worked in ETF product management and capital markets at Vanguard, the second-largest ETF issuer, and returned to ProShares as a senior ETF product manager overseeing the flagship dividend growth suite and the lifecycle of more than 200 ETFs and mutual funds. He joined Sprott in April 2022 and now leads product strategy for a 13-fund U.S. lineup spanning gold and silver miners, uranium, copper, lithium, nickel and rare earths, within a firm that manages roughly $65 billion.
His method starts with long-term supply-and-demand imbalances in individual materials, then looks for pure-play companies — those deriving at least half their revenue or assets from the target metal. REXC shows the approach: with index provider Nasdaq, Sprott screens roughly 1,000 mining companies twice a year for pure-play credentials, and the resulting fund holds 41 issuers with about 96% rare earths exposure, 95% to 98% of it in Australia, the United States and Canada. His recurring caution to investors is to look past fund names, because many strategies branded as rare earth funds hold only 15% to 30% rare earth exposure.
Schoffstall lays out this thinking in Sprott webcasts and reports such as "Rare Earths: Critical Elements at a Critical Moment," "Copper: Wired for the Future" and "The Uranium Miners Opportunity," and in interviews on programs like Bloor Street Capital. His current focus is the West's effort to build ex-China supply chains for critical minerals. He frames it as a multi-year shift — new metals mines take about 16 years on average to go from discovery to production — and tells investors to approach the theme with a long horizon and tolerance for short-term volatility.

Sprott's Rare Earth Ex-China ETF REXC | Steve Schoffstall and Jimmy Connor
- Top takeaway The guest argues that despite the name, rare earths are not geologically scarce — they are rarely found in concentrations that make mining economically viable, which he says is the real bottleneck.
- He emphasizes that China now controls roughly 69% of rare earth mining and over 90% of refining and magnet production, and is using export controls to restrict access.
- He cites dysprosium (used in magnets) as a concrete example, saying its price has risen from $100/kg to $900/kg as a result of those restrictions, supporting the sector investment case.
- The guest frames the policy backdrop as a major tailwind: Western governments are reshore-ing production and offering incentives, which he expects to create opportunities outside China.
- He positions the new ETF as differentiated versus competing products, arguing many funds marketed as rare earth ETFs are actually diversified or concentrated in other metals, sometimes with single-digit rare earth exposure.
Sprott's Steve Schoffstall outlines REXC, a rare earths ex-China ETF holding 34 companies screened from ~1,000 miners for >=50% rare earth revenue. China now controls about 69% of rare earth mining and over 90% of refining and magnet production, prompting Western reshoring investment. Dysprosium prices have spiked from $100 per kilo to $900 per kilo as China tightens rare earth export controls. REXC's holdings weigh about 48% Australia, 40% United States and 8% Canada, with roughly 38% large cap and the rest mid and small cap. The fund claims about 96% pure-play rare earth exposure, while some competing 'rare earth' ETFs hold single-digit exposure.

- Top takeaway Steve argues that China now controls about 69% of rare earth mining and over 90% of refining and magnet production, and that Western countries are putting unprecedented funding and policy in place to reshore production away from Chinese control.
- He points to dysprosium's move from $100/kg to $900/kg as direct evidence that Chinese export controls are tightening supply and lifting prices.
- He pitches Sprott's new REXC ETF as the only fund solely focused on rare earths, with ~96% pure-play exposure versus single-digit exposure in many competing products marketed under the rare earth label.
- He stresses that the investment case is multi-year: rare earth prices have 'gone through the roof', Western reshoring programs are real, and the ETF's ~48% Australia / ~40% US / ~8% Canada weighting captures the geography of that build-out.
China controls 60% of mining, 91% of refining, and 94% of magnet output, pushing Western governments to fund non-Chinese rare earth supply. Dysprosium is up 300% and terbium is up 400% on Chinese export restrictions, with Western buyers still struggling to secure heavy rare earths. Heavy rare earths are hardest to extract economically; China refines roughly 98% of heavy metal, the gap G7 nations are racing to close. Rainbow Rare Earths targets 2029 production by recovering rare earths from phosphate mining waste stockpiles, sidestepping traditional mining risk. Humanoid robots could use 3 to 5 times more permanent magnets per unit than an EV, opening a major new rare earth demand vector.
