## Contributions and company outcomes

### Apollo’s Rebecca resource and 2021 acquisition [sls_nick_apollo]

2010–2021 · issuer reported · high materiality

Apollo’s 2021 annual report names Castleden managing director and reports an April 2021 Lake Rebecca mineral resource update of 29.1Mt at 1.2g/t for 1.105Moz. Solstice reports that Apollo acquired and delineated Rebecca during his tenure. Apollo disclosed Ramelius held 74.01% on 26 November 2021; Ramelius reports it obtained 100% control on 17 December 2021. These are company-level milestones and do not isolate Castleden’s individual contribution or establish a shareholder return.

**Attribution:** Role overlaps event; causation unproven. Managing-director role and company milestones overlap; the sources do not isolate his personal contribution or attribute project outcomes to him.

**Relevance:** Relevant experience for an explorer, without proving mine delivery.

### Nanadie exploration and funding progressed [sls_nick_nanadie]

FY2026 and quarter ended 30 September 2026 · issuer reported · high materiality

Solstice’s September 2026 quarterly reports ongoing Nanadie drilling outside the existing 40.4Mt resource boundary and cash of A$41.3m with no debt. Its 2026 annual report describes an A$32.6m gross institutional placement and calls Nanadie an exploration discovery. These are company-reported results, not an updated resource, completed feasibility study, or operating mine.

**Attribution:** Role overlaps event; causation unproven. CEO oversight overlaps these reported activities; specific personal contribution is not isolated.

**Relevance:** Funding and exploration progress matter to the company’s current stage.

## Evidence gaps

- The chair and CEO source establishes Apollo tenure by year, but exact Apollo dates, individual technical contribution, independent qualifications and later corporate records remain unverified.

- Individual topic-by-topic searches, original regulator and court records, and complete prior-employer records were not fully researched; negative findings or clearance are not established.

- Independent educational and membership verification was not completed.
