## Environmental record
### Dargues biodiversity-offset delay and qualified follow-up [angus_wyllie_dargues_offset]
August 2022 request; follow-up records through FY2024 · issuer reported · medium materiality
An August 2022 letter to NSW Planning, signed by then Dargues GM Angus Wyllie, requested six additional months to secure a biodiversity offset after the original end-August deadline could not be met. It cited uncertainty over the relevant plant community type, market availability, unsuitable properties and landholders declining to proceed. The 51st Dargues CCC minutes (meeting 27 March 2024) later say a BSA had been lodged with the DPE Biodiversity Credit Supply Taskforce and that the offset site was secured, with credits still subject to taskforce determination. Aurelia’s FY24 annual report subsequently says negotiations with NSW and a third-party landholder had progressed to establish Dargues offsite and onsite offsets. These records establish progress and a lodged agreement, but leave a status conflict and do not establish final BSA approval/registration or credit issuance/retirement by cutoff. The 2022 request is a compliance-timing issue; neither source establishes personal wrongdoing by Wyllie.
**Attribution:** Role overlaps event; causation unproven. Wyllie signed the company request as GM; evidence supports role overlap and a reported compliance issue, not a finding of personal wrongdoing.
**Relevance:** Relevant to the executive’s documented function and the company’s operating and development profile; the degree of personal contribution is limited to the evidence stated.

### Dargues wastewater overflows and EPA undertaking during GM tenure [angus_wyllie_dargues_overflows]
13–19 July 2023 incidents; enforceable undertaking 12 July 2024; restoration monitoring June–July 2025 · documented · medium materiality
Two wastewater holding-tank overflows occurred at Dargues on 13 July and 18–19 July 2023 while Wyllie was General Manager of Dargues. The NSW EPA says the first overflow reached the mine sediment dam; in the second, more than 190,000 litres escaped and some entered Spring Creek. The EPA issued a clean-up notice and required operational changes; Big Island Mining Pty Ltd, Aurelia’s wholly owned subsidiary, entered a legally binding enforceable undertaking dated 12 July 2024 that includes a $125,000 community-project contribution and water-management/rehabilitation presentations. EPA reporting estimates 192.4 kL overflowed and says an unknown amount reached Spring Creek. Upper Deua Catchment Landcare’s June/July 2025 follow-up describes restoration funded by Aurelia under the undertaking; monitoring recorded about 133 plants killed by unusual frost and the group was considering replanting/protection options. The evidence establishes a site-level environmental incident and company-level regulatory response during Wyllie’s Dargues GM period, not his personal conduct or culpability.
**Attribution:** Role overlaps event; causation unproven. Wyllie’s issuer biography places him as Dargues GM from June 2021 to June 2024, overlapping the events. The regulator names Big Island Mining, not Wyllie, as the undertaking party; no reviewed record attributes the valve failures or notification delay to him personally.
**Relevance:** Material to environmental controls and incident response in a senior mine-operations role; later remediation was underway but its completion is not established by the reviewed follow-up.

## Suitability for the current role
### Documented role scope and role fit [angus_wyllie_role_fit]
Current role at cutoff · analyst inference · low materiality
Angus Wyllie joined Aurelia as GM Dargues in June 2021 and moved to GM Cobar Region in June 2024. Aurelia and Equilar report about 22 years of mine-site experience in Australia and Canada, mining-engineering education, an MBA and statutory manager competency. As Dargues GM, Wyllie signed an August 2022 request for more time to secure a biodiversity offset. Later CCC minutes report a BSA lodged and site secured, while the FY24 annual report describes negotiations still progressing; final approval/credit issuance remains unverified. The role fit reflects relevant site operations experience with a documented company compliance-timing issue, not personal wrongdoing.
**Attribution:** Responsibility not applicable. This is a limited role-scope inference from the issuer-documented position; it is not an outcome or personal-performance claim.
**Relevance:** The role is pertinent to oversight or execution of the company’s disclosed business; evidence on individual effectiveness is limited.

## Evidence gaps
- The Dargues offset follow-up is not fully resolved: March 2024 CCC minutes say a BSA was lodged and the site secured, while Aurelia’s FY24 annual report says negotiations were still progressing. The reviewed sources do not establish BSA registration/approval or credit issuance/retirement by cutoff.
- The wastewater undertaking is against Big Island Mining Pty Ltd, not Wyllie personally. Landcare documented remediation planting and monitoring, but its June/July 2025 status report leaves replanting/protection work under consideration; completion was not established.
- Prior employer titles, tenure dates and performance outcomes remain incomplete where no dates were provided in the opened biographies; no personal causal attribution is inferred from company results.
- Credential and education claims are reported by issuer or secondary biography and were not independently checked with issuing institutions or professional bodies.
- Person-specific open-web searches are not exhaustive court, regulator, sanctions, safety, environmental or credential checks; a no-relevant-finding result is not a clearance.
