UAMY vs. TMC: A Faceoff Between Two Emerging Critical Minerals Strategies

United States Antimony (UAMY) is showing near-term operational traction with H1 2025 revenue up 160% to $17.5m and nine‑month revenue of $26.2m (up 182%), gross margin expansion to ~28%, cash and investments of $38.5m and the restart of domestic antimony mining at Stibnite Hill with bulk samples >10% Sb. The Metals Company (TMC) remains a development-stage deep‑sea nodules play with no recent revenue but published PFS/IA studies implying a combined NPV >$23bn, liquidity of $165m plus >$400m potential from warrants, and an aim toward commercial recovery in Q4 2027; management projects long‑run EBITDA margins near 50% as refining scales. Both firms advance U.S. critical‑minerals supply‑chain goals but present divergent risk/reward profiles: UAMY with immediate cashflow and government demand alignment, TMC with long‑cycle capital and regulatory execution risk.

Analysis

Contrarian angles: Consensus underprices de‑risking value in U.S. processing incumbents—if UAMY secures a DLA off‑take within 6–12 months, upside could re‑rate multiples 2x from current depressed levels; conversely, market may be overenthusiastic about TMC’s timeline—commercial recovery by Q4 2027 assumes smooth permitting and capex that historically take +18 months to secure. Historical parallels: rare‑metal restarts (e.g., US tungsten in 1970s/80s) saw lumpy cashflows and sudden permit setbacks—expect lumpy news and position sizing accordingly. Unintended consequence: rapid US domesticization could invite export controls or subsidy conditionality that compresses margins and complicates off‑taker agreements.

Key Decisions for Investors

• Establish a 1% portfolio position in TMC via a long‑dated call spread (buy Dec 2029 calls, sell Dec 2030 calls at higher strike or similar structure) sized to risk no more than 0.5% NAV loss; rationale: pay for optionality on 2027 commercial recovery while capping premium—reassess at permit certification or major JV funding within 6–12 months.
• Trim or hedge existing UAMY equity exposure by 30–50% immediately; if maintaining exposure, buy 3–6 month puts with strike ~20–30% below spot or implement a collar to limit downside, given 425% YTD run and Zacks Rank #4 downside risk in next 3 months.
• Execute a pair trade: long TMC (0.75% NAV via call spread) and short UAMY (0.5% NAV or buy 3‑6 month puts) to exploit long‑cycle seabed optionality vs near‑cycle antimony mean‑reversion. Close or rebalance after key catalysts (UAMY DLA contract or TMC permit certification) within 6–12 months.
• Shift 3–5% of commodity/allocation from early‑stage junior explorers into downstream refiners and strategic partners (e.g., Korea Zinc equivalents or large integrated refiners) that have agreed offtake; these names should capture margin improvement if U.S. policy favors domestic processing—target reallocation within 30 days and monitor DLA/DIBC announcements.
