The beachhead
Cobalt and rare earths, from industrial wastewater.
Lithium-from-brine is the most crowded, best-funded link in the chain — your water-only resin has no edge there. The whitespace is the non-lithium metals — cobalt and rare earths (magnesium and manganese secondary; not nickel, which is in glut) — recovered from industrial aqueous effluent: mining leach raffinate and tailings / acid-mine-drainage first, semiconductor-CMP and power-plant FGD as fast-followers.25,35,46

The resin column
A water-regenerated zwitterionic resin that selectively pulls cobalt and rare earths from a dilute, multi-cation stream — using water instead of harsh acids, and leaving the discharge cleaner.
Why the edge is decisive here
Four reasons this stream fits the resin.
Dilute, multi-cation streams
Industrial effluent carries several metals at once, at low concentration — exactly the regime a multi-ion-selective resin is built for, and where bulk DLE sorbents struggle.
Removal is legally mandatory
On NPDES-limited effluent, taking metals out isn't optional — it's the discharge permit (Cu 2.07, Ni 2.38 mg/L). That's the durable, metal-price-immune fee; the recovered metal is upside.35
Clean water as a co-product
Water-only regeneration leaves a cleaner, reuse-ready stream — a value the metal-only extraction crowd can't offer, and one a generator pays for on its own.
The business model
Refining-as-a-service, not a commodity sale.
The proven analog is Nth Cycle: a modular unit, a per-kilogram processing fee, and the customer keeps the metal — a model that just attracted a $1.1B, ten-year offtake.48,49 Olokun slots in as the technology party in someone else's plant: the effluent generator owns the feedstock, the capex, and the offtake; Olokun keeps the IP and a recurring fee. That's the capital-light, recurring-margin position a ~$1.1M-raised balance sheet can actually support.
The IP play
Turn the first-right-of-refusal into a narrow exclusive.
Olokun doesn't hold exclusive rights to NREL's resin — but it holds a first right of refusal through the West Gate relationship.12 That's a timing option. And because the cobalt / rare-earth-from-effluent field is one NREL itself isn't commercializing, the smart move isn't fighting for crowded lithium rights — it's exercising the ROFR to convert it into a narrow, field-of-use exclusive license for industrial-effluent critical minerals: cheaper, more attainable, and the exact lane the edge wins in.
