Contributions and company outcomes

Company-level project and delivery record

Most recent report through cutoff · issuer reported · low materiality

The FY2026 annual report describes exploration at Zopkhito; the historical foreign estimate is not represented as a JORC-compliant Mineral Resource. Drilling and resource conversion remain exploration work, not delivered mine production.

Attribution: Role overlaps event; causation unproven. The individual held the stated role during some or all of the reported period; available evidence does not isolate personal contribution.

Relevance: Provides the company outcome against which the executive’s delivery record should be assessed.

Business failures and setbacks

FY2026 loss and financing dependence

Year ended 30 June 2026 and September 2026 · documented · medium materiality

Krakatoa reported a FY2026 net loss of A$5.784 million versus A$2.522 million in FY2025 and A$739,459 cash at 30 June. The directors’ going-concern assessment depended principally on further equity funding; the audit identified going concern as a key audit matter. The annual report also says A$4 million was raised after year-end. Independent reporting on the September quarter states cash was A$2.03 million after those placements.

Attribution: Role overlaps event; causation unproven. Company-level financial outcome during management tenure; additional capital raised after 30 June is not part of the June cash balance and individual causation is not established.

Relevance: Shows the funding and capital-allocation demands during the team’s tenure.

Environmental record

EL8153 Sugarloaf regulator audit: diesel spill observation and response

2020–2022 activity; audit published 2022 · documented · low materiality

The NSW Resources Regulator’s compliance audit covering Krakatoa’s EL8153 exploration activity from 2020–2022 found no non-compliances. It did record a small diesel spill at drill site SDD002 as an observation of concern: the drilling contractor had not reported it and the exploration manager was initially unaware. The site manager cleaned it during the audit; the manager later followed up with the driller to reinforce reporting. The audit said the spill was unlikely to cause material environmental harm and was not reportable or a reportable offence. The report does not identify Major or Locke as personally involved. Their company leadership tenure overlapped the period, which is an oversight context only.

Attribution: Role overlaps event; causation unproven. Company-level exploration management oversight; the regulator did not identify either executive as responsible for the spill or as having breached a requirement. Corrective response is documented.

Relevance: Exploration-stage environmental reporting controls relevant to the CEO and executive-chair roles.
