Item 8.01. Other Items

On May 27, 2025, the official gazette of the government of Brazil, Diário Oficial da União, published the granting by Brazil's Ministry of Mines and Energy to us of mining concession status ("Portaria de Lavra") with respect to our lithium mineral right number 833.356/2007 with a size of 1,536.45 hectares. This particular mineral right contains most of the currently discovered mineralized lithium ore bodies within our Neves Project.

This development represents a significant milestone as a mining concession constitutes the highest-level title of ownership for a mineral right in Brazil. In broad terms, it provides ownership of the mineral right in perpetuity and grants the right to mine the substance for which it was issued (in this case, lithium) without volume limitations, provided that customary periodic reporting requirements under the Brazilian mining code and any other applicable regulations are satisfied.
