## Personal achievements

### Stibnite field-work supervision [zinsser_field_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.
