ADELAIDE, AU / ACCESS Newswire / October 21, 2025 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or the Company) is pleased to confirm that a $15m placement to institutional investors announced on 14 October 2025 has been completed (Placement).¹ The Placement was priced at $1.25 per share, with 12 million new Placement shares issued.¹

The Placement was led by Franklin Templeton which has acquired an initial ~3.8% interest in Barton's expanded equity capital structure following completion. Barton also welcomes Donald Smith Value Fund, L.P. and other new institutions to its share register, and thanks its existing North American investors for their further support. Barton's expanded capital structure now comprises 237,961,810 fully paid ordinary shares (before the SPP).

Barton is also opening a non-underwritten SPP targeting $2.5m (before costs), allowing eligible shareholders to acquire new Barton shares at the same Placement price (SPP Offer).¹ The SPP Offer will open tomorrow, 23 October 2025 with a letter to shareholders (Letter) and booklet containing the full SPP details (SPP Offer Booklet) published on the ASX. The Letter and an application form will be available to eligible shareholders.

The SPP is expected to close at 5:00pm (AEDT) on Thursday, 6 November 2025. However, Barton may close the SPP early without notice. The Company notes that the Company's last SPP, opened on Tuesday, 9 April 2024 was heavily oversubscribed and closed early after only one week.² Interested Eligible Shareholders are therefore encouraged to apply as soon as possible following the opening of the SPP.

To apply for SPP Shares, you must make payment directly by BPAY using the unique reference number shown on your personalised application form. You can obtain a copy of your personalised application form online - prior to receipt of materials posted by mail - with your Securityholder Reference Number (SRN) or Holder Identification Number (HIN). Further details will be included in the Letter.

Commenting on the Placement and SPP, Barton Managing Director Alexander Scanlon said:

"This Placement further strengthens our already high quality share register, and is a further endorsement of Barton's strategic regional platform and strategy. We thank our new and existing institutional shareholders for their support as we enter the next phase of our corporate evolution, targeting ‘Stage 1' commissioning by the end of 2026. We have an exciting journey ahead in South Australia as we lead the re-establishment of the Gawler Craton's gold district.

"Barton is very well capitalised to pursue its objectives. The SPP is an opportunity for all other eligible shareholders to extend their participation in Barton's story."
