¹ Green Technology Metals news release dated July 24, 2025, titled "LARGE, HIGH GRADE RUBIDIUM RESOURCE IDENTIFIED AT THE SEYMOUR PROJECT", JORC Code, 2012 Edition - Table 1. The 2023 Mineral Resource Estimate is reported above 0.2% Li2O cut-off. The cut-off is based on lowest potential grade at which a saleable product might be extracted using a conventional DMS and/or flotation plant and employing a TOMRA Xray sorter (or equivalent) on the plant feed. A number of pegmatites outcrop at surface thus the mineral resource is likely to be extracted using a conventional drill and blast, haul and dump mining fleet. The Seymour Mineral Resource is reported using open-pit mining constraints. The open-pit Mineral Resource is only the portion of the resource that is constrained within a US$4,000/t SC6 optimized shell and above a 0.2% Li2O cut-off grade. The optimized open pit shell was generated using: $4/t mining cost, $15.19/t processing costs, mining loss of 5% with no mining dilution, 55 degree pit slope angles, 75% Product Recovery. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

² Buxton Resources news release dated February 17, 2025, titled "Graphite Bull Resource Expands 345%", JORC Code, 2012 Edition -Table 1. The MRE is reported above the 200 m RL, which is approximately at a depth of 200 m below topographic surface. This depth is considered to be a reasonable depth to which conventional open pit mining will reach, based on in-house mining studies, benchmarking and DCF modelling which indicates that strip ratios below 5:1 will be required to define economic mining scenarios. The MRE is reported above a cut-off grade of 7% TGC, which is recommended by Buxton and based upon analyses of commodity prices, other similar projects, cost estimates for mining and processing, and assumptions regarding a breakeven TGC grade. Mineral Resources that are not Mineral Reserves do not have demonstrated economic
viability.
