## Contributions and company outcomes
### Cerro Bayo resource growth and acquisition are documented at company level [damien_koerber_asl_delivery]
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.

## Environmental record
### Cerro Bayo environmental compliance programme remains in execution [damien_koerber_environment_case]
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.

## Litigation and enforcement
### Local claimant reports a criminal complaint and alleges historical Los Domos and current conflict concerns [damien_koerber_allegation_2026]
Claim published 20 August 2026; claimed underlying role/activity in 2017; official Los Domos process 2019–2023 · alleged · medium materiality
A local activist/blog publisher, Andrés Gillmore, states that he filed a criminal complaint naming Damien Koerber and cites RUC 2601282110-6. The post alleges Koerber was involved as Southern Gold operations manager in 2017 Los Domos activity and accuses him/Andean of current improper influence through community-project support. These are allegations by the claimant, not findings of fact. The historic corporate exploration matter is separately supported by SMA’s official record: its docket shows a 2021 requirement for Southern Gold to enter Los Domos into Chile’s environmental assessment system and later process documents; it shows no associated sanctioning proceeding in that requirement file. The claimant’s further assertion of an active complaint could not be verified against an official public docket or disposition by the cutoff. No evidence reviewed establishes that community collaboration was improper.
**Attribution:** Responsibility unresolved. The claimant names Koerber and cites a case number, but the complaint itself, an official docket, charging document, or judicial determination was not located. The SMA matter establishes company-level regulatory history; it does not establish individual wrongdoing. No finding of misconduct is made.
**Relevance:** Material to an exploration/operations leader in Chile because it concerns a publicly reported allegation and the historical regulatory record; its unverified status substantially limits weight.

## Suitability for the current role
### Experience broadly matches current Chief Operating Officer – Americas and General Manager Exploration remit [damien_koerber_role_fit]
Current role at 9 October 2026 · analyst inference · medium materiality
The issuer identifies Damien Koerber as Chief Operating Officer – Americas and General Manager Exploration 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.
