SHARE PURCHASE PLAN RAISES $3.1 MILLION

• Share Purchase Plan (SPP) to eligible existing shareholders closed on Friday 5 September, raising $3.1 million before costs, on the same terms as the $20 million institutional placement announced on 14 August 2025.

• The proceeds will be used to advance the development of Centaurus’ flagship Jaguar Nickel Sulphide Project in northern Brazil and to support the Jaguar Strategic Partnering and debt funding processes ahead of a Final Investment Decision (FID), which is targeted for H1 2026.

• The funds will also underpin ongoing exploration at the exciting Boi Novo Copper Project.

Centaurus Metals Limited (ASX Code: CTM, OTCQX: CTTZF) (CTM or Centaurus) is pleased to announce the results of the nonunderwritten Share Purchase Plan (SPP), which was announced on 14 August 2025.

The SPP was open to eligible shareholders registered on the record date, being 5:00pm (Perth time) on Wednesday, 13 August 2025. The SPP was undertaken at $0.36 per new fully-paid ordinary share (SPP Share) in the Company, being the same price as the placement also announced to the ASX on 14 August 2025 which raised $20 million before costs (Placement).

Under the terms of the SPP, eligible shareholders were able to subscribe for up to a maximum of $30,000 of new fully-paid ordinary shares (SPP Shares) together with one free attaching option for every two SPP Shares subscribed for (SPP Options), on the same terms as the Placement.

The SPP closed on Friday 5 September 2025, with the Company receiving valid applications for 8,549,850 New SPP Shares, raising a total of $3.1 million before costs.

Holding statements for the SPP Shares, SPP Options and options to be issued pursuant to the Placement (Placement Options) will be sent to shareholders today.

The funds raised in the SPP, together with the Placement proceeds, will be used to underpin the continued development of CTM’s 100%-owned Jaguar Nickel Sulphide Project in northern Brazil, including progressing the ongoing Jaguar Strategic Partnering and debt funding processes in advance of a Final Investment Decision (FID), as well as for ongoing exploration of the Boi Novo Copper Project and for general working capital purposes.

The combined proceeds of the capital raising, together with Centaurus’ existing cash of $9 million (as at 30 June 2025), will ensure that the Company is in a strong position to complete the final pre-development, permitting and funding stages for the Jaguar Project – including Strategic Partnering and off-take ahead of a FID next year.

Management Comment

Commenting on the outcome of the SPP, Centaurus’ Managing Director, Darren Gordon, said:

“We are very pleased with the strong support received from existing shareholders through the SPP, with the final amount raised exceeding our target. The strong take-up by existing shareholders under the SPP, together with the recent wellsupported institutional share placement, is testament to the quality of the Jaguar Nickel Project – which is one of the very few major new nickel sulphide projects globally currently moving towards development.

“These funds further strengthen our balance sheet, putting us in a strong position to advance ongoing development activities at Jaguar while also progressing the strategic partnering process and funding negotiations that will enable Centaurus to move towards a Final Investment Decision on the project development, which is targeted for delivery in the first half of next year.”
