Rock Tech Lithium Inc. reports developments tied to lithium processing, critical minerals supply chains, and project financing. Company news centers on the Red Rock lithium converter in Ontario, the Guben lithium converter in Germany, and the Georgia Lake lithium mining project, with updates on engineering design, digital twin technology, strategic partnerships, and capital-expenditure planning.
Recurring announcements also cover private placements, market-making arrangements, prospectus filings, and policy developments affecting battery materials and critical minerals processing in Canada and Europe.
Rock Tech Lithium (RCKTF) will attend CEM's Muskoka Capital Event in Muskoka, Ontario, from September 25 to 27, 2026.
Rock Tech has 18 scheduled 20-minute meetings at the event, alongside approximately 47 companies and over 55 investors. The company plans to provide an update on its Canadian mining project and processing plant.
Rock Tech Lithium (RCKTF) has signed agreements with Siemens Canada to advance development of a Digital Process Twin and support the Definitive Feasibility Study (DFS) for its planned Red Rock Lithium Converter in Ontario.
The agreements are the first implementation phase of a March 2026 strategic memorandum of understanding that aims to bring German lithium conversion expertise and industrial digitalization technology to the project. Siemens’ Digital Twin will model plant processes, energy flows and material streams across the full project lifecycle, from feasibility through engineering, construction and operations, allowing Rock Tech to test and optimize design, efficiency, emissions and reliability before major capital is committed. Siemens will also provide specialized support in process control, instrumentation and automation architecture to Rock Tech’s DFS project team, with the DFS expected to conclude by mid-December 2026.
Rock Tech Lithium (RCKTF) plans an intensive investor outreach program in September 2026, including a virtual investor roundtable on September 21 to discuss its made-in-Ontario mine-to-converter strategy and project development and production timelines.
Management will also attend multiple conferences and policy events in Germany, Hungary and Canada between September 12 and 30, engaging with investors, industry participants and policymakers as panelists and presenters.
Rock Tech Lithium (RCKTF) and Thunder Bay Pulp and Paper received the 2026 Northern Innovators Award at the Cen-Can Expo Gala in Thunder Bay. The award recognizes their collaboration to evaluate crude tall oil, a by-product of Ontario's pulp and paper industry, as a potential locally sourced flotation reagent for lithium processing. The CMIF-supported project also involves Queen's University and aligns with Rock Tech's plan to build an integrated mine-to-converter lithium supply chain in Northern Ontario.
Rock Tech Lithium (OTCQX: RCKTF) signed a binding long-term offtake agreement dated July 24, 2026 with Geneva-based trader Transamine SA for spodumene concentrate from its wholly owned Georgia Lake project in Ontario. The deal initially runs for seven years from 2028, with annual renewal options for up to five additional years, and covers ramp-up deliveries from 50,000 dry metric tonnes (dmt) in the first year to 100,000 dmt per year thereafter, subject to ±10% volume flexibility in Rock Tech’s favour and adjustment after the definitive feasibility study.
Pricing is linked to the Fastmarkets 6% Li₂O CIF China benchmark, with grade adjustment and a qualified floor price. The agreement can be converted into an offtake for battery-grade lithium hydroxide and/or carbonate to support Rock Tech’s planned Red Rock Lithium Converter. It also outlines a development prepayment facility of up to US$80 million, bearing interest at three‑month CME Term SOFR plus 2.95% and repayable mainly via concentrate deliveries over 24 months after first delivery, subject to multiple project financing, permitting and technical conditions precedent.
Rock Tech Lithium (OTCQX:RCKTF) has been awarded $262,500 from Ontario's Critical Minerals Innovation Fund to evaluate crude tall oil, a by-product of the province's pulp and paper sector, as a potential locally sourced flotation reagent for lithium processing.
The CMIF-supported project, undertaken with Thunder Bay Pulp and Paper and Queen's University, aims to assess processing efficiency, localized reagent supply and potential cost optimization for Rock Tech's Georgia Lake Lithium Project, while supporting its broader Ontario mine-to-converter strategy and a made-in-Ontario lithium supply chain.
Rock Tech Lithium (OTCQX:RCKTF) reported voting results from its June 26, 2026 annual general and special meeting. Holders of 6,722,634 shares, about 5.60% of outstanding shares, were represented.
Shareholders elected all director nominees, re-appointed MNP LLP as auditor, approved an omnibus equity incentive plan, and authorized a potential share consolidation of 1-for-2 to 1-for-15, subject to board determination and TSX Venture Exchange acceptance.
Rock Tech Lithium (OTCQX:RCKTF) entered an option agreement to acquire 100% of the 9,875-hectare Victory Project lithium property in Northwestern Ontario. The project hosts two surface spodumene-bearing LCT pegmatite occurrences with grab samples up to 5.11% and 3.48% Li₂O.
The option totals CAD $600,000 cash and CAD $400,000 in shares over 24 months, plus a 2% NSR royalty and resource-based milestone payments. Victory is early-stage with no current mineral resource and unverified historical data, and remains subject to TSX Venture Exchange acceptance.
Rock Tech Lithium (OTCQX:RCKTF) began trading its shares on Xetra, Deutsche Börse’s electronic trading system, under ticker RCK. mwb Wertpapierhandelsbank AG acts as designated sponsor, which is expected to support higher liquidity and turnover.
According to Rock Tech, the Xetra listing broadens access to German and European institutional investors, complements its Canadian listing and planned NASDAQ listing, and does not change its status as a Canadian issuer. The company highlights lithium converter projects in Germany and Canada supporting regional battery supply chains.
Rock Tech (OTCQX:RCKTF) reported completion of a CMIF-supported ore-sorting program at the Georgia Lake lithium project in Ontario. Tests using UV laser and XRT sorting removed about 25–45% waste and upgraded ore by 1.4–1.8x, indicating a potential pathway to cut future crushing and concentrator CAPEX by up to 50%.
The work, done with Queen's University and STARK Resources, may improve project economics versus the 2022 PFS baseline and supports restarting drilling, value-engineering and studies toward a possible Definitive Feasibility Study, within Rock Tech's broader Ontario mine-to-converter strategy and planned Red Rock Converter.
