Announcement PDF ASX Release 14th October 2024 Copper Wolf Project: IGO Earns 51% & JV Established • IGO have acquired a 51% interest in the Copper Wolf JV Tenements • IGO & BUX have formed a 51% / 49% JV • IGO may earn another 19% by spending an aggregate A$5.35M Buxton Resources Ltd (‘Buxton’; ASX: BUX & BUXO) hereby provides an update to shareholders in relation to the Copper Wolf Project, in Arizona, USA. On 3 October 2024, IGO Ltd (IGO) notified Buxton that: 1. IGO have met the Stage 1 Earn-in Requirement of the Copper Wolf Agreement (see ASX Announcements 22 August 2022 and 2 September 2022), that being expenditure of AUD $350,000 (exclusive of GST); and, 2. IGO have earned a 51% interest in the BUX / IGO JV Tenements (Figure 1). The parties have now formed a 51/49 JV, which IGO shall manage. The parties will form an operating committee and IGO will propose a programme and budget for consideration and approval by the operating committee. IGO have 6-months in which to notify BUX should they intend to earn a further 19% JV Interest by solefunding a further $5M in exploration expenditure. The parties will otherwise continue to operate the JV on a co-contributing 51% IGO / 49% BUX basis. This announcement is authorised by the Board of Buxton Resources Ltd.

Porphyry Cu-Mo mineralisation at Copper Wolf has been dated at 70.3 Ma (Laramide age) and is largely concealed by a post-mineral (Tertiary) sequence of volcanic and sedimentary rocks. The Project is located within one of the most prolifically endowed copper belts in the world (Figure 2), yet it has not seen any drilling since the early 1990s. Buxton’s 2022 airborne magnetic survey was the first geophysical work undertaken since the early 1960s. Historic exploration has consisted of relatively wide spaced drilling which focussed on significant supergene copper mineralisation located where the NW trending Cow Creek Fault intersects Laramide hypogene porphyry style mineralisation. Buxton is targeting underground bulk mineable copper-molybdenum mineralisation. In this context, Buxton’s exploration approach can leverage the significant advances and ready availability of modern geophysical targeting tools and mineral systems knowledge that have been developed since exploration in this area ceased many decades ago. Figure 1: Copper Wolf Project tenure situation showing ~30.5 km2 area (pale orange coloured polygons) for which Buxton has 100% interest in the subsurface estate (unencumbered only by IGO's First Right of Refusal, see Table 1, Section 2). These areas include substantial basement exposures indicating potential for copper-molybdenum porphyry mineralisation at shallower depths in comparison to the Bobcat, Rattler and Coyote prospects. The BUX / IGO JV covers ~12.5 km2, and includes the supergene blanket which has been the focus of previous exploration including historical resource estimates. BRAL owns a 33.62 acre surface parcel with associated access and water rights.
