3 Under-the-Radar Mining Stocks to Buy With $100 Right Now

The article profiles three speculative U.S.-focused critical-metals plays: TMC The Metals Company, a pre-revenue deep-sea miner targeting polymetallic nodules containing nickel, cobalt, copper and manganese that is awaiting regulatory clarity from the ISA (with potential alternative U.S. pathways); MP Materials, owner/operator of the Mountain Pass rare-earth mine and domestic magnet processor that received a $400 million DoD investment and a $500 million partnership with Apple in July 2025; and USA Rare Earth, a pre-revenue developer of the Round Top deposit in Texas that recently secured roughly $3.1 billion in Department of Commerce and private funding and aims for operation around late 2028. Each company is positioned to affect domestic supply chains for EV batteries, permanent magnets and defense applications, but all remain capital-intensive and largely speculative investments for long-term holders.

Analysis

Market structure: Short-to-medium term winners are MP Materials (MP) and USA Rare Earth (USAR) — MP’s processing + DoD/Apple backing gives it pricing power in NdPr and magnet supply, while USAR’s Round Top adds optionality by 2028. TMCWW is a binary deep‑sea supply option with huge execution and regulatory risk; if domestic onshore capacity hits 20–40% of US demand by 2030, spot NdPr/Ni/Cu tail risk could push prices 20–40% below peak scenarios, compressing margins for high-cost foreign suppliers.

Risk assessment: Tail risks include ISA rulings or national litigation blocking deep‑sea mining (TMCWW) and multi‑year capex overruns or project financing failure at USAR (probability medium, impact high). Time buckets: days (permit/funding headlines move stocks 10–30%), months (funding tranches, DoD milestones), years (operational ramp 2026–2029); hidden dependency is concentrated offtake (Apple/DoD) — loss of a single anchor could cut revenue forecasts >30%.

Trade implications: Favor selective longs in MP (cash‑flowing, strategic partner support) and staged, milestone‑linked long exposure in USAR; avoid or short TMCWW until regulatory clarity. Use long-dated (12–24 month) LEAP calls on MP to capture structural upside and buyputs or outright small short for TMCWW to hedge existential risk. Rotate into defense/supply‑chain beneficiaries and reduce exposure to China‑dependent rare‑earth processors on signs of US capacity ratcheting up.

Contrarian view: Market underestimates legal/ESG blockade risk to deep‑sea mining and overestimates speed of commercialization; conversely it may underprice strategic premiums for domestic processors (MP/USAR). Historical parallel: 2010 China export shock produced volatile spikes then collapse once alternatives scaled — expect asymmetric volatility and policy interventions (subsidies/buybacks) that can prop domestic survivors.

Key Decisions for Investors

• Establish a 2–3% portfolio long position in MP (MP) within 30–90 days — prefer shares or buy Jan‑2027 LEAP calls — thesis: capture 12–24 month upside from DoD/Apple offtake and processing ramp; trim if NdPr spot price falls >30% or MP misses processing throughput targets by Q4 2026.
• Initiate a speculative 0.5–1% staged long in USA Rare Earth (USAR): tranche buys on (a) confirmation of FID or commercial debt closing and (b) 2026 construction milestones; target hold to late‑2028 operational window, expect high dilution risk and 3x+ upside if on schedule.
• Take a tactical 0.5–1% short/exposure hedge to TMC The Metals Company (TMCWW) via buying 9–12 month OTM puts or small short position; reverse/cover immediately if ISA or US permitting occurs within 90 days or if company secures irrevocable offtake/finance.
• Execute a relative‑value pair: long MP (2%) vs short TMCWW (0.5–1%) to express quality domestic processing over speculative deep‑sea supply; size to keep net market beta modest and reassess after each regulatory or funding catalyst (monitor weekly headlines and monthly funding disclosures).
