Surge Battery’s Nevada North lithium PFS: capex, returns and mine plan for engineers
Reviewed by Tom Sullivan

First reported on MINING.com
30 Second Briefing
Surge Battery Metals’ updated prefeasibility study for the Nevada North lithium project in Nevada lifts the after-tax NPV to US$9.81 billion and IRR to 24% at US$24,000/t LCE, while cutting initial stage-one capex to US$2.77 billion and trimming operating costs by about 10% from US$5,243/t. The 42-year, conventional open-pit claystone mine, held 68/32 with Evolution Mining, is designed for non-blasting extraction and on-site production of battery-grade lithium carbonate, averaging 92,250 t/y and peaking at about 111,400 t in year seven. Proven and probable reserves of 218.3 Mt at 3,928 ppm Li (4.56 Mt LCE) underpin a two-stage plant ramping from 55,900 t/y to double capacity, with first production targeted for H2 2031.
Technical Brief
- Metallurgical recovery has been increased from 82.8% to 84.9% in the updated PFS.
- Operating costs have been reduced by about 10% from the earlier estimate of US$5,243/t LCE.
- Updated resource totals 657.5 Mt at 3,007 ppm Li, equating to ~10.5 Mt LCE in situ.
- Proven and probable reserves of 218.3 Mt at 3,928 ppm Li yield 4.56 Mt LCE in the mine plan.
- Claystone mineralisation extends over 4.7 km strike length and more than 2 km width at Nevada North.
- Total planned LCE production over the 42‑year mine life is 3.87 Mt, excluding inferred resources.
- Even at US$16,800/t LCE (30% below base price), after‑tax NPV8 remains about US$4.6 billion.
- Nevada North Lithium JV ownership is 68% Surge Battery Metals and 32% Evolution Mining, with no inferred tonnes scheduled.
Our Take
With an after-tax NPV of US$9.81 billion at Nevada North and a 42-year mine life, Surge Battery Metals now sits at the upper end of project-scale valuations among the lithium items in our mining database, which may help it compete for U.S. strategic-minerals support highlighted in the September 2026 critical minerals strategy coverage.
Amnesty International’s criticism of Nevada North alongside Thacker Pass and Rhyolite Ridge signals that, despite strong lithium metrics and long-life reserves in Nevada, permitting and Indigenous rights challenges could be a pacing factor for Surge’s development schedule rather than project economics alone.
