Contributions and company outcomes

Mine operations leadership during Araxá exploration and permitting advance

2025-2026 · issuer reported · medium materiality

The 2025 investor presentation names Rios as Director of Mining Operations and describes over 23 years at CBMM, including as production manager. FY26 reports significant drilling and initiation of the Araxá licensing process. This is relevant time overlap, not evidence that a mine is operating or that Rios directly produced these results.

Attribution: Role overlaps event; causation unproven. The role is documented; operational responsibility is prospective because St George’s Araxá remains a development project.

Relevance: Relevant experience to future operating plans; no operating performance at St George has yet been demonstrated.

Suitability for the current role

Role fit supported; individual record remains incomplete

Evidence cutoff 2026-10-09 · analyst inference · low materiality

Dated primary company filings and appointment records now support the disclosed role and relevant parts of the person’s professional background. They do not establish a complete career chronology, independently verify every credential, or provide a broad personal performance or adverse-record conclusion.

Attribution: Responsibility not applicable. This is a scoped role-fit assessment, not an attribution of a company outcome.

Relevance: Role alignment matters to execution in the current position, but the reviewed evidence does not establish full delivery or control outcomes.
