Rox upsizes Share Purchase Plan to A$18m in response to strong demand

Successful completion of the institutional placement and the SPP will see Rox emerge with A$218m cash (before costs) to fully fund the equity component of the Youanmi Gold Project development

WA gold exploration and development company Rox Resources Limited ( “Rox” or “the Company” ) ( ASX: RXL ) is pleased to advise that it upsized its recently announced Share Purchase Plan (“ SPP” ) to A$18 million, in accordance with the terms of the SPP Offer Document released to the ASX on 3 December 2025.

The decision followed extremely strong demand for the SPP and reflects the Company’s commitment to its supportive retail shareholders.

Applications under the SPP, which closed at 5:00pm AWST, Tuesday 16 December 2025 (“ Closing Date” ), totalled approximately A$24.4 million, significantly exceeding the original A$10 million target announced on 14 November 2025.

The SPP was open to 5,827 eligible shareholders and the Company received valid applications from 1,407 of those shareholders, representing a participation rate of approximately 24%. The SPP was undertaken in conjunction with the Company’s A$200 million two-tranche institutional placement. As announced on 21 November 2025, Tranche 1 of the Placement was completed raising A$66 million (before costs). Tranche 2 of the Placement of A$134 million (before costs) was approved by shareholders at the General Meeting on 17 December 2025 and is expected to be completed on 23 December 2025.

The proceeds of the institutional placement and the SPP will fully fund the equity component of the Youanmi Gold Project development, as noted in the ASX Announcement on 14 November 2025.

Rox Resources Managing Director & Chief Executive Officer Phill Wilding commented:

“We are thrilled to have received such strong interest in the SPP, much of which has been received from our loyal retail shareholders and shows great confidence in the progress of development at Youanmi.

“We have taken the opportunity to increase the size of the SPP allocation as reward to those loyal shareholders and further de-risk the funding requirement for Youanmi, along with allowing us to strengthen our drilling plans.

“This is an exciting time for Rox Resources, as we strategically grow the Company and maintain our trajectory of becoming one of the highest-grade new gold producers in Western Australia.”
