Patented technology
An independent, non-HPAL route to Class 1 nickel, protected by a granted US patent and two international (PCT) applications.
Route to Class 1 nickel· TRL 6 · Indonesia
A new path to
critical-minerals security.
Indonesia supplies roughly 60% of the world's mined nickel, and refining is concentrated in even fewer hands. BANIQL is an independent, non-HPAL route, proven at pre-pilot scale, operating continuously since early 2025, with battery-grade product evaluated by potential customers and a signed offtake LOI in hand.

BANIQL / BEST™: atmospheric leaching at up to 95 °C and ~1 bar. Indexed to HPAL = 100%.
The approach
A cleaner route to battery-grade nickel
01
Selective, atmospheric chemistry
Our process selectively leaches nickel while rejecting iron, and runs at atmospheric pressure, unlike HPAL's high-temperature, high-pressure autoclaves. It triples nickel concentration on the way to product.
02
Lower energy, circular by-products
The route uses about 70–80% less energy than HPAL, and is designed to convert its residues into agricultural fertilizer and magnesium products (field trials underway) rather than permanent tailings.
Why it matters
Nickel demand triples. Supply stays concentrated.
Demand grows roughly 2–3× by 2035 for EV batteries, superalloys for spacecraft and jet engines, and gas turbines powering AI data centers, while ~60% of mined supply sits in one country and Class 1 nickel flips to structural deficit around 2028–2030.
02
Validated product
Over 1,000 kg of battery-grade MHP produced at our pre-pilot facility and evaluated by potential customers in Korea, Japan, Taiwan, and the US.
03
Feedstock line of sight
A long-term, non-binding ore-supply MoU in Indonesia anchors feedstock for scale-up, from nickel ore through to nickel sulfate.
04
Production capabilities
A pre-pilot facility operating in Indonesia since February 2025, processing more than 100 kg/day of ore at atmospheric pressure.
05
Commercial traction
A signed, non-binding offtake LOI with a Korean customer, estimated at US$16.5–21M, validating demand for new, diversified sources of Class 1 nickel.
From pre-pilot to commercial
Modular refineries, sited next to the ore.
The same atmospheric-pressure chemistry scales into modular commercial refineries, free of the heavy autoclave footprint that defines HPAL.
