Announcement PDF 22 JULY 2025 ASX/MEDIA RELEASE GROUP MINERAL RESOURCE AND ORE RESERVE STATEMENT as at 31 December 2024 Established Australian copper-gold producer and explorer, Aeris Resources Limited (ASX:AIS) (Aeris or the Company) is pleased to release its 31 December 2024 Group Mineral Resource and Ore Reserve Statement for its 100% owned Tritton, Cracow Operations and the North Queensland, Jaguar and Stockman Projects. Key Highlights • The Group Mineral Resource is now estimated at 48.9Mt, containing 784kt of copper, 1,361koz of gold, 1,045kt of zinc and 36.6Moz of silver 1. • The Group Ore Reserve is now estimated at 14.1Mt, containing 249kt of copper, 398koz of gold, 413kt of zinc and 11.8Moz of silver. • New reporting policy for Tritton, aimed at improving the Resource-to-Reserve conversion ratio, partly contributed to reduction in Tritton Mineral Resource. Forward Work Plan Aeris is focused on growing and sustaining high-quality Reserves and Resources across our core assets. In FY26, we’re increasing resource definition and exploration drilling at Tritton, Cracow, and Jaguar—targeting Resource and Reserve growth, mine life extensions, and long-term value creation. Aeris’s Executive Chairman Andre Labuschagne said: “Our copper and gold focused Mineral Resource and Ore Reserve estimates highlight the quality, scale, and diversity of our asset base. A focused forward work plan targets high-value opportunities to drive growth and extend asset life. At Tritton, enhanced resource reporting methodology will improve future Resource-to-Reserve conversion, strengthening our growth pipeline and supporting long-term development confidence” 1 Our Mineral Resource estimates are inclusive of reported Ore Reserve estimates Mineral Resource and Ore Reserves Statement 1 31 December 2024 Group Mineral Resource and Ore Reserve Estimates Group Mineral Resource and Ore Reserve Estimates are presented in Table 1 and Table 2.

Mineral Resource and Ore Reserves Statement 4 31 December 2024 Changes in Group Mineral Resources Estimates (net of mining depletion) Group Mineral Resource estimate represents a net decrease of 39kt in contained copper, 71koz in contained gold, 19kt in contained zinc, and 2Moz in contained silver relative to estimates at 31 December 2023, as shown across our assets in Figure 1 to Figure 5.

A decrease of 3Mt was due to a new reporting policy for underground Mineral Resource that incorporates conceptual stope shapes. This change replaces the previous block-by-block copper cutoff method and more accurately reflects economic and mining constraints, removes isolated lower grade and remnant ore blocks and will improve Resource to Reserve conversion at the Tritton Operations 2. Additional reductions were attributed to mine depletion and sterilisation (-1.8Mt). When the new reporting policy is applied to the previous Mineral Resource it showed a similar reduction in tonnage indicating the tonnage reduction is due to a change in policy and not the underlying geology. These decreases were partially offset by additions from resource extension drilling at the Constellation deposit, which contributed 1.4Mt to the Mineral Resource. • Cracow Operations Mineral Resource tonnage decreased by 0.5Mt compared to the previous reporting period. Mineral Resource reductions included model changes (-0.4Mt), mine depletion (-0.4Mt) and sterilisation (-0.3Mt), which was partially offset by resource additions (0.7Mt) from resource extension drilling throughout the reporting period. • Jaguar Projects Mineral Resource tonnage decreased by 1.3Mt, mainly due to a revised resource model for the Teutonic Bore deposit based on an updated geology interpretation and classification schema. • North Queensland Project Mineral Resource tonnage decreased by 0.1Mt due to changes to the sterilisation reporting criteria. • Stockman Project Mineral Resource has not changed since the previous reporting period. 2 See further explanation within the Tritton Operation Mineral Resource Estimate section Mineral Resource and Ore Reserves Statement 7 31 December 2024 Changes in Group Ore Reserves Estimates (net of mining depletion) Group Ore Reserve estimates represent a net increase of 4kt in contained copper, and decreases of 8koz of contained gold, 95kt of contained zinc, and 1.8Moz of contained silver relative to estimates at 31 December 2023.

However, depletion was partly offset by additions at the Tritton, Budgerygar and Avoca Tank underground mines. • Cracow Operation increased due to Mineral Resource additions and subsequent mine planning reviews. • North Queensland Project increased, despite the completion of mining operations at Mt Colin. This is due to the declaration of the maiden Ore Reserve for the Barbara project following the completion of the feasibility study. • Jaguar Project decreased following completion of technical studies that concluded additional mineable Mineral Resources are required to support a restart. Technical Studies have been paused while further exploration drilling is undertaken. Therefore, there is no Ore Reserve estimate for the Jaguar Project. • Stockman Project Ore Reserve estimate remained unchanged. Feasibility studies focused on processing pathways are currently underway.
