Green Technology Metals Limited’s latest update on its Seymour Lithium Project reveals strong resource estimates and promising metallurgical results. Advanced testing shows competitive lithium recoveries with low operating costs, highlighting potential value upside for investors in the expanding lithium market.
Green Technology Metals has released an extensive technical report detailing its updated resource estimates and metallurgical testwork at the Seymour Lithium Project in Ontario, Canada. The report, prepared to comply with JORC Code guidelines, confirms that the deposit has been robustly defined through over 370 diamond drill holes totaling more than 56,000 metres. The modelling used Ordinary Kriging on 1‑metre downhole composites with a cut‑off grade of 0.2% Li2O, supported by open‐pit parameters such as a mining cost of US$4 per tonne, processing costs of US$15.19 per tonne, 55‑degree pit slopes, and 75% product recovery. These technical indicators underline the rigorous approach taken to quantify the deposit’s grade and tonnage.
The document describes detailed bench‑scale testwork using Heavy Liquid Separation (HLS) and Dense Media Separation (DMS) methods on composites from the Seymour North Aubry deposit. The laboratory tests produced high‑grade lithium concentrates with Li2O levels between 6.5% and 6.8%, while achieving global recoveries ranging from approximately 63% to 72%. The study also involved bulk pilot tests whereby additional processing steps, including magnetic separation, were incorporated to improve the final product quality by reducing iron content. Extensive block modelling, variography analysis, and statistical validations contribute to the company’s confidence in classifying the resource into Indicated and Inferred categories.
On the positive side, the report offers bullish signals for the project’s future prospects by confirming that the deposit meets key industry benchmarks and that recovery parameters are in line with conventional flowsheet designs. The technical data and defined processing options point to a resilient asset that could yield high‑grade lithium concentrate for the growing electric vehicle and battery storage markets. Conversely, the study also highlights some inherent risks. Although the lab‑scale test results are promising, further bulk pilot testing is needed to fully validate the processing strategy. Additionally, minor uncertainties remain in scaling both the metallurgical process and environmental management plans prior to commercial production.
Overall, the announcement reinforces the potential of the Seymour project while acknowledging that additional testwork and process optimization will be critical before moving to full‑scale production. Investors are encouraged to consider both the promising technical indicators and the ongoing development risks as part of their assessment of the company’s long‑term growth prospects.
