RC1’s Eastern Goldfields portfolio currently comprises the Redcastle Project Area, the TBone Belt and the Kilkenny Belt Package. Following completion of the Kilkenny Belt earn-in transaction, RC1 will have earned a 60% interest in the Kilkenny Belt Package, which adds a substantial regional exploration footprint to the Company’s Eastern Goldfields strategy.
Within the Redcastle Project Area (RPA), Queen Alexandra (QA) and Redcastle Reef (RR) host the Company’s current Mineral Resources of 42,000 ounces reported in accordance with the JORC Code (ASX: RC1 30 June 2025); while nearby targets including Morgan’s Castle East, Sligo, Coronation, South Queen and Battery Lode provide additional exploration and development upside.
Following completion of the Kilkenny Belt earn-in transaction and subject to grant of pending applications, RC1’s Eastern Goldfields portfolio of interests comprises interests in 85 exploration and mining tenement interests across the Redcastle Project Area, TBone Belt and Kilkenny Belt, comprising 70 live tenements and 15 pending applications. The portfolio covers approximately 150 km², comprising granted tenements and live tenement applications. This total includes approximately 2,026.38 ha of pending tenement applications, which remain subject to grant.
Potential future cash flow from mining operations at RR and QA, should provide non-dilutive funding support for priority exploration across the Redcastle Project Area, TBone Belt and Kilkenny Belt.

Redcastle continues to expedite its dual-track strategy focused on advancing mining activities toward potential future revenues while progressing exploration across multiple high-priority gold targets in Western Australia's Eastern Goldfields.
During the first half of 2026, Redcastle commenced mining operations at its QA and RR gold deposits located within granted Mining Lease M39/318, marking a transformational milestone in Redcastle's evolution from explorer to gold producer.

Mining activities are being undertaken through the Redcastle–BML Ventures Joint Venture (RB JV), with BML Ventures (BML) acting as the project operator.BML is funding 100% of the capital requirements to first revenues from the RR and QA deposits, substantially reducing Redcastle's upfront capital exposure while preserving the Company's balance sheet for exploration and resource growth initiatives.
The commencement of mining for Redcastle establishes a clear pathway to near-term gold production and cash flow while positioning the Company as an integrated exploration and mining business.
Importantly, the capital-light structure of the RB JV enables Redcastle to leverage anticipated production revenues to support ongoing exploration across the Redcastle Gold Project, while simultaneously advancing its Kilkenny and T-Bone project areas.
Potential future cash flow from RR-QA, should provide non-dilutive funding support for priority exploration across the Redcastle Project Area, TBone Belt and Kilkenny Belt.
