Personal achievements
Named technical manager and report contributor
2020–2026 · issuer reported · medium materiality
BBX announced the appointment of chemical engineer Edmar Medeiros as technical manager in July 2020, and its 2024 Três Estados statement identifies him as a test-result compiler. A secondary profile updated in October 2026 still lists that title; the current mandate was not confirmed by a dated recent issuer release.
Attribution: Individual involvement documented. The named roles and contribution are issuer-reported; personal economic performance is not measured.
Relevance: Evidence of processing and testing involvement, with current role uncertain.

Business failures and setbacks
Earlier bioleach work and a disputed supplier invoice
2023–2026 · issuer reported · medium materiality
The FY2026 report says the Brazilian subsidiary could not replicate the supplier’s bacterial-leaching results in Brazil, terminated the licence in June 2024, and disputes a US$350,000 supplier invoice. The annual report does not identify who made the technical or commercial decisions.
Attribution: Role overlaps event; causation unproven. Technical-manager involvement is documented in 2024; no personal failure, contractual fault or decision is established.
Relevance: Relevant to assessing prior processing technology development.
