Lithium’s $100B, 134‑mine build‑out: project pipeline risks for mine planners
Reviewed by Tom Sullivan

30 Second Briefing
Global lithium demand is projected by Benchmark Mineral Intelligence to reach nearly 7 million tonnes LCE by 2050, up from 2.11 million tonnes this year, requiring the equivalent of 134 new mines at an average 36,000 t/y capacity and over $100 billion in capital. Australia’s share of mined supply is expected to fall from 29% to 20% as operations deplete, while North America could rise from 1.7% to 13% and Europe to 5.5%, both constrained by permitting, unproven extraction technologies and community opposition. Benchmark assumes recycling could supply almost half of lithium by mid-century, yet timing of battery retirements and cost competition with new mines remain critical uncertainties for project financing and long‑term supply planning.
Technical Brief
- EVs’ share of lithium demand is projected to rise from 55% today to 76% by 2050.
- Stationary energy storage demand has grown >60% annually for two years, then moderating to ~5%/y to 2030.
- Batteries already consume 92% of lithium, up from ~70% in 2020, tightening non-battery supply availability.
- Benchmark’s upside scenario to ~9 Mt LCE by 2050 would need ~180 mines and >$150 billion capex.
- Capex requirement to 2040 is estimated at ~$64 billion, assuming recycling supplies a substantial demand share.
- Recycling growth is constrained by end-of-life timing; every shortfall tonne must be substituted by primary mining.
Our Take
Benchmark Mineral Intelligence also underpins our recent coverage of uranium and copper supply gaps, signalling that its projection of 134–180 new lithium mines by 2050 is part of a broader pattern of structural tightness across multiple energy-transition commodities rather than a lithium-only outlier.
The forecast jump in North America’s mined lithium share from 1.7% to 13% by 2050 aligns with US Department of Energy funding activity in our database, suggesting that midstream policy tools (grants, tax credits, offtake support) will be as critical as greenfield permitting in closing the region’s supply–demand gap.
With recovered material expected to provide about half of lithium supply by mid‑century, the capex estimate of $64 billion to 2040 under substantial recycling implies that projects in regions like Europe, which currently contribute under 1% of mined supply, may lean heavily on recycling and conversion capacity rather than large new greenfield mines.
