Rock Tech Lithium Clarifies Historical Resource Estimate for Lopare Project

Rock Tech Lithium Inc. has recently clarified its technical disclosure concerning the Lopare Lithium Project located in Bosnia-Herzegovina. This clarification follows a review by the Ontario Securities Commission, which prompted the company to provide additional context regarding the mineral resource estimate originally reported in February 2025. The estimate, categorized as a "historical estimate" under National Instrument 43-101, is derived from a report by CSA Global from November 30, 2022. It indicates a significant potential for lithium and boron resources based on an analysis of 14,035 assay samples collected from 69 drill holes, employing a block model methodology.

The historical estimate calculates lithium carbonate at a price of US$40,000 per tonne and boric oxide at US$1,322 per tonne, using a cut-off grade of 400 ppm Li2O. However, Rock Tech cautions that this estimate does not adhere to current NI 43-101 standards and lacks a compliant technical report. The company emphasizes the need for additional technical work, including field exploration and diamond drilling, to verify or potentially upgrade this historical estimate. This due diligence is critical as Rock Tech aims to support the credibility of its resource claims and align its disclosures with regulatory requirements.

In conjunction with these clarifications, Rock Tech Lithium is advancing its strategic transaction with Arcore, which seeks to create a fully integrated European lithium company. This partnership looks to combine Rock Tech's Guben Converter in Germany with Arcore's Lopare project to enhance the lithium supply chain for electric vehicle production. The successful execution of this transaction is contingent upon raising a minimum of €50 million and obtaining necessary regulatory approvals, with a targeted closing date set for the third quarter of 2025. This initiative reflects Rock Tech's commitment to supplying sustainable lithium, emphasizing its role in the transition towards electric mobility and renewable energy solutions.

Rock Tech’s focus on improving its resource estimates and advancing strategic partnerships positions the company favorably within the burgeoning lithium market. As demand for lithium surges due to the increasing production of electric vehicles, the company’s efforts to ensure compliance with regulatory standards and enhance its resource base are crucial. These developments not only bolster Rock Tech’s operational capabilities but also strengthen its credibility in the lithium sector, paving the way for future growth and investment opportunities.
