- Binding offtake with Geneva-based commodity trading house Transamine SA secures long-term commercial pathway for Georgia Lake's full planned production
- The agreement preserves Rock Tech's ability to process Ontario lithium into battery-grade chemicals at its planned Red Rock Lithium Converter
- The agreement provides for a development prepayment facility of up to US$80 million.
- The offtake agreement covers a seven-year initial term, starting in 2028, with an option to extend for up to five additional years, covering up to 100,000 dry metric tonnes per year
TORONTO, July 27, 2026 /PRNewswire/ -- Rock Tech Lithium Inc. ("Rock Tech" or the "Company") (TSX-V: RCK) (OTCQX: RCKTF) is pleased to announce that it has signed a binding long-term offtake agreement dated July 24, 2026, with Transamine SA ("Transamine"), a Geneva-based global commodity trading house, for spodumene concentrate produced at the Company's wholly owned Georgia Lake project ("Georgia Lake") in Ontario, Canada. The agreement supports a long-term commercial pathway for Georgia Lake while reflecting growing market confidence in Rock Tech's integrated Ontario strategy. The agreement currently contemplates deliveries beginning in 2028, subject to the contractual delivery provisions and any adjustments agreed by the parties following completion of the definitive feasibility study.
The agreement marks another important step in advancing Rock Tech's integrated Ontario lithium supply chain: it secures long-term commercial pathway for full planned production of an estimated minimum of 100,000 dry metric tonnes per year of spodumene concentrate from Georgia Lake's while maintaining flexibility for the Company to capture additional value through domestic lithium conversion. The agreement also provides a framework for a development prepayment facility of up to US$80 million to support the Georgia Lake Project.
Binding Offtake for Georgia Lake Concentrate
Under the agreement, Transamine will purchase spodumene concentrate from Rock Tech over an initial term of seven years, starting in 2028, which may be renewed annually by mutual agreement for up to five additional years. Contracted volumes ramp from 50,000 dry metric tonnes during the first year of deliveries to 100,000 dry metric tonnes annually thereafter, subject to a ±10% tolerance in favour of Rock Tech and terms and conditions of the agreement. The quantities and timeline will be reviewed and mutually adjusted based on the results of the definitive feasibility study.
Pricing references the Fastmarkets spodumene concentrate benchmark (min. 6% Li₂O, CIF China), adjusted for delivered grade. The agreement incorporates a qualified floor price subject to specified resale-market, inflation-adjustment and project-financing provisions.
Option to Convert into Battery-Grade Lithium Chemicals
The agreement is structured to support Rock Tech's integrated Ontario mine-to-conversion strategy. Should Rock Tech determine that the concentrate is required for its Red Rock Converter, the parties will convert the arrangement into an offtake for battery-grade lithium hydroxide monohydrate and/or battery-grade lithium carbonate, subject to a mutually agreed amendment establishing the applicable specifications, conversion mechanism, pricing, delivery schedule and other terms. Transamine's take-or-pay commitment continues through and after any such conversion, adjusted for the applicable product, price and delivery terms.
This flexibility allows Rock Tech to sell spodumene concentrate while preserving the option to supply converted lithium chemicals to battery and cathode customers when the planned Red Rock Lithium Converter is developed and commissioned.
"This agreement demonstrates how Rock Tech is turning critical minerals ambition into execution," said Mirco Wojnarowicz, Chief Executive Officer of Rock Tech. "It provides a long-term, commercial foundation for the Georgia Lake mine's future production, strengthens our financing pathway, and – together with the prepayment facility – brings us another step closer to building the integrated mine-to-converter platform with the flexibility to convert raw material into battery-grade lithium chemicals through our Red Rock Lithium Converter. Together with the prepayment facility, the agreement brings us another step closer to building an integrated mine-to-converter platform and supporting a stable, secure supply of battery-grade lithium for Canada and its allies."
Up to US$80 Million Development Prepayment Facility
To support Georgia Lake project, the agreement provides for a framework for a development prepayment facility of up to US$80 million. The prepayment carries interest at three-month CME Term SOFR plus 2.95% per annum, accruing quarterly, and would be repaid by set-off against concentrate deliveries over a 24-month period beginning with first delivery. Any amount outstanding after that period would become due and payable in cash.
The exact amount and terms of the prepayment will be documented separately and agreed once the definitive feasibility study is complete. Availability of the facility is subject to the satisfaction (or waiver by the buyer) the following conditions precedent:
- full project equity financing committed
- all material permits, licences, land access rights and environmental approvals in place
- no material adverse change
- legal, financial and technical due diligence satisfactory to the buyer
- no unresolved title, land, litigation, environmental or community matter that could delay production
- final assays, impurity profile, metallurgical test work and product specifications available and satisfactory to the buyer.
