BOA to Acquire Thaduna and Green Dragon Copper Deposits in WA

25 June 2026 | Western Australia - BOA Resources has announced a transformational copper transaction that will see the company acquire the Thaduna and Green Dragon copper deposits in Western Australia’s Murchison region.

BOA has entered into an agreement to acquire 100% of Core Value Australia NL, which has separately agreed to acquire the Thaduna and Green Dragon deposits from Sandfire Resources.

On completion, BOA will own the Thaduna and Green Dragon deposits, consolidate its ownership of the Neds Creek Copper Project and expand its copper exploration footprint in the Murchison Copper Belt.

The Thaduna and Green Dragon deposits host a combined JORC 2012 Mineral Resource Estimate of 5.3Mt at 2.3% copper for 121,000 tonnes of contained copper.

Thaduna accounts for the majority of the Resource, with 4.1Mt at 2.5% copper for 103,000 tonnes of contained copper. Green Dragon contains 1.2Mt at 1.5% copper for 18,000 tonnes of contained copper.

BOA said the acquisition will expand its Murchison Copper Belt footprint to approximately 1,378.6km², including the Thaduna and Green Dragon Mining Leases, granted exploration licences, granted prospecting licences and exploration licence applications.

Chair and Managing Director Cath Norman described the transaction as transformational for BOA, saying it moves the company from holding an interest in a prospective copper exploration package to controlling a broader regional copper portfolio with granted mining leases, drill-ready targets and substantial exploration upside.

Why it matters: The acquisition gives BOA a larger and more advanced copper platform in Western Australia at a time when copper demand remains strongly supported by electrification, grid investment, electric vehicles, renewable energy and battery storage.

The Thaduna and Green Dragon deposits are located on granted Mining Leases, which BOA described as a key strategic advantage and potential foundation for future resource development.

The transaction also brings Sandfire Resources onto BOA’s register as a substantial shareholder. Subject to completion, BOA will issue Sandfire 27.8 million shares, giving Sandfire an approximate 6.2% post-transaction shareholding.

CVA principal and experienced geologist Adrian Griffin is also expected to join the BOA board as a Non-Executive Director on completion of the transaction. Griffin has more than 40 years of mining industry experience across exploration, development, financing and project delivery.

BOA said the acquisition creates a stronger regional exploration position across the Neds Creek copper corridor. The company has identified multiple drill-ready copper targets, with historical drilling at several prospects returning ore-grade copper intersections.

Ricci Lee remains BOA’s first priority for resource definition drilling. The prospect is located close to Thaduna, sits in a similar geological setting and has already returned multiple ore-grade copper intercepts from historical drilling.

BOA said it remains funded to progress the transaction and its planned exploration activities, with a cash position of approximately $3.2 million supporting the acquisition and 2026 drilling plans.

Drilling is targeted to commence in late July 2026, initially focused on Ricci Lee, Rooneys and other high-priority Neds Creek prospects.

The company’s immediate next steps include completing remaining approvals, convening a shareholder meeting, completing the CVA and Sandfire acquisition arrangements, undertaking heritage surveys, integrating the Thaduna and Green Dragon datasets and developing a broader exploration and resource growth plan across the expanded copper portfolio.

For Western Australia’s resources sector, the transaction highlights renewed interest in copper projects with existing Resources, granted tenure and regional exploration upside.
