Contributions and company outcomes

Cerro Bayo resource growth and acquisition are documented at company level

2024–30 June 2026 · issuer reported · medium materiality

Andean states that it completed the Cerro Bayo acquisition and expanded/established a high-grade silver-gold resource; by 30 June 2026 its reported resource was 136 Moz AgEq. The chairman directly credited Timothy Laneyrie and the team with the acquisition and resource establishment. This is an issuer-reported company outcome; for people other than Laneyrie, individual contribution is not established. The project remains on care and maintenance and current restart/feasibility work is planned, not delivered.

Attribution: Role overlaps event; causation unproven. The chairman specifically credited Laneyrie and the team with the acquisition/resource establishment; the source does not allocate separate causal responsibility to each manager. For Laneyrie, that is a direct issuer attribution; for other executives, role overlap only.

Relevance: Relevant to current project stewardship, but delivery remains exploration/resource definition rather than restarted production.

Annual Report for the transitional year ended 31 December 2025 (Annual Report, Chairman’s Letter; the chair attributes the acquisition and resource establishment to Laneyrie and the team); Cerro Bayo Project (Cerro Bayo Project, resource statement as at 30 June 2026 and forward-work-plans section, lines 56–58 and 80–95)

Environmental record

Cerro Bayo environmental compliance programme remains in execution

2024–9 October 2026 · documented · medium materiality

The SMA initiated case D-029-2024 with four charges against the Cerro Bayo operator relating to dust suppression over tailings, revegetation, groundwater monitoring and related environmental approvals. The official docket shows a compliance programme was approved on 6 November 2025, no sanction is listed, and the programme remained in execution at the cutoff. The annual report describes the matters as historical non-compliance attributable to previous operators and says the programme was approved, suspending the sanctioning process subject to full and timely execution, with no significant environmental damage identified. The regulator record controls on status; issuer characterization is attributed to the issuer. This is a company/project-level record and no reviewed source assigns responsibility to the listed executive.

Attribution: Role overlaps event; causation unproven. The regulator proceeding names the operating company, not the individual. Current or prior role overlap is not evidence of personal causation; the annual report attributes historic issues to previous operators.

Relevance: Relevant as oversight and remediation context for a team advancing a restart; current programme completion was not established by cutoff.

Suitability for the current role

Experience broadly matches current Environment Manager remit

Current role at 9 October 2026 · analyst inference · medium materiality

The issuer identifies Sofia Aravena as Environment Manager and describes relevant professional experience in the corporate biography. This supports a limited role-fit inference. Employer biographies are not independently verified, formal qualifications and full career dates remain incomplete, and this is not a personal clearance.

Attribution: Responsibility not applicable. No personal outcome responsibility is inferred by the role-fit assessment.

Relevance: Role-relevant experience is disclosed by the issuer, but independent credential and chronology checks remain incomplete.
