Personal achievements

Stibnite field-work supervision

2015–2017 · documented · medium materiality

Perpetua’s 2023 Form 10-K names Zinsser among the supervisors of 2015–17 field work, including drilling. This establishes a documented technical role but not delivery of a mine or financial returns.

Attribution: Individual involvement documented. The former operator names him as co-supervisor; no sole technical responsibility or commercial outcome is inferred.

Relevance: Evidence for geology and field-management experience.

Relevant experience and evidence limits

As of the dated 2025–2026 sources · analyst inference · low materiality

Attribution: Responsibility not applicable. Role-fit inference is based on issuer-reported roles; individual outcomes and qualifications are not independently verified.

Relevance: Relevant to Horse Heaven technical and strategic execution.
