Rock Tech Lithium Inc. (CVE: RCK) (OTCMKTS: RCKTF) has secured a long-term offtake agreement with Swiss commodity trader Transamine SA for spodumene concentrate from its Georgia Lake lithium project in Ontario.
Announced on Monday, this deal will strengthen the company’s commercial and financing plans ahead of expected production.
The binding agreement, dated July 24, covers planned deliveries beginning in 2028. However, the timeline and volumes remain subject to the results of the project’s definitive feasibility study and any changes the two companies later approve.
Additionally, the deal establishes a framework for a development prepayment facility worth up to USD$80 million to help finance construction of the Georgia Lake project.
Rock Tech said the agreement covers the mine’s planned production of at least 100,000 dry metric tonnes of spodumene concentrate each year. The company also retains the flexibility to redirect material into domestic lithium processing if its planned Red Rock Lithium Converter moves forward.
During the first year, Transamine will purchase 50,000 dry metric tonnes of concentrate. Subsequently, annual deliveries will increase to 100,000 dry metric tonnes, subject to a 10 per cent volume tolerance in Rock Tech’s favour and any revisions following completion of the feasibility study.
The initial agreement runs for seven years. Additionally, both companies may extend it through annual renewals for up to five more years by mutual agreement.
Pricing will follow the Fastmarkets benchmark for six per cent lithium oxide spodumene concentrate delivered into China, with adjustments based on product grade.
The agreement also includes a qualified floor price. However, that protection depends on specific resale market conditions, inflation adjustments and project financing provisions.

Flexibility allows Rock Tech to respond to market conditions
Rock Tech designed the arrangement to support its broader mine-to-converter strategy in Ontario.
If the company decides to process Georgia Lake concentrate at its proposed Red Rock Lithium Converter instead of exporting raw material, both parties can amend the agreement.
Under that scenario, Transamine would purchase battery-grade lithium hydroxide monohydrate, battery-grade lithium carbonate or a combination of both instead of spodumene concentrate.
Meanwhile, the companies would negotiate updated product specifications, pricing, delivery schedules and conversion terms. Transamine’s take-or-pay commitment would continue after the change, adjusted for the new products.
Rock Tech said the flexibility allows it to respond to changing market conditions while preserving the opportunity to supply higher-value battery materials to customers in North America and elsewhere.
Chief executive officer Mirco Wojnarowicz said the agreement represents another step toward turning the company’s critical minerals plans into commercial execution.
He said the deal establishes a long-term sales pathway for Georgia Lake production. It also strengthens Rock Tech’s ability to finance the mine. Additionally, he said the financing and conversion option move the company closer to an operation that produces Canadian battery-grade chemicals.
The proposed prepayment facility could provide up to USD$80 million in development funding.
The financing would carry interest at the three-month CME Term SOFR plus 2.95 per cent annually, with interest every quarter.
Rock Tech would repay the financing by offsetting concentrate deliveries over a 24-month period beginning with the first shipment. Consequently, any unpaid balance remaining after that period would become payable in cash.
The company said it will finalize the amount borrowed and the detailed financing terms after completing the definitive feasibility study.

Company must resolve multiple disputes
Several conditions must also be satisfied before the financing becomes available.
These include securing full project equity financing, obtaining all required permits, licences, land access rights and environmental approvals.
Furthermore, Transamine must complete legal, financial and technical due diligence to its satisfaction before providing the financing.
The company must also resolve any outstanding land issues, litigation, environmental matters or community concerns that could delay production.
In addition, Rock Tech must provide final assay results, impurity data, metallurgical testing and product specifications acceptable to the buyer.
Georgia Lake is the company’s wholly owned lithium project in northwestern Ontario.
Spodumene concentrate serves as a raw material for producing lithium chemicals used in rechargeable batteries for energy storage systems.
Rock Tech has promoted the Georgia Lake mine and Red Rock Lithium Converter as part of an integrated Canadian supply chain intended to produce battery materials domestically rather than exporting raw concentrate alone.
