## Contributions and company outcomes

### Midas added Otavi to its exploration portfolio; operating delivery remains unproven [mm1_mark_calderwood_batch_outcome]

FY2025 · issuer reported · low materiality

Midas’ FY2025 report described the acquisition of the Otavi copper-silver-gold project in Namibia as a transformational portfolio addition and showed a year-end market-capitalisation increase, while the company remained loss-making (FY2025 loss A$2.77m). Exploration success and future project value remain prospective; no operating mine delivery is established in this record.

**Attribution:** Role overlaps event; causation unproven. The cited record establishes a company or employer event. For role\_overlap, the executive held a relevant role in the period, but the reviewed source does not establish personal causation or an individual enforcement finding. For employer\_only, no individual link or matching tenure was established.

**Relevance:** This is relevant context for assessing Managing Director at the same employer; it should not be read as proof of individual performance or misconduct.
