Announcement PDF 18 DECEMBER 2024 ASX/MEDIA RELEASE MURRAWOMBIE PIT UPDATE • Open pit mining contract signed with Mackellar Group • Mobilisation has commenced with key personnel and equipment starting to arrive on site • Mining scheduled to start early February 2025 Established Australian copper-gold producer and explorer Aeris Resources Limited (ASX:AIS) (Aeris or the Company) is pleased to announce an update of its 100% owned Tritton Operations in NSW. Aeris’ Executive Chairman, Andre Labuschagne, said “the Murrawombie open pit cutback is a key project for Tritton. With over a million tonnes in Reserve, the cutback delivers a significant proportion of the mill feed in FY26. Non-acid forming waste material from the stripping will be used to cap the old Murrawombie heap leach pads, greatly reducing our future rehabilitation obligations. We are looking forward to working with our open pit contractor, Mackellar on this critical project for Tritton.” Open Pit Project The Murrawombie open pit has a Probable Reserve of 1.34Mt grading 1.3% Cu and 0.2g/t Au 1 . Mackellar Group was the successful tenderer for the open pit mining contract to undertake the cutback. Mining will be undertaken in two stages with Stage 1 involving limited stripping to access remaining ore from the base of the old pit prior to the major stripping and ore mining in Stage 2. A fleet of excavators, dozers and Cat 777 trucks will be deployed over a 14-month contract period, with mobilisation under way and prestripping works commencing in February 2025. 1 Refer to “Group Mineral Resource and Ore Reserve Statement” released to the ASX on 17 June 2024 ABN 30 147 131 977 ABN 30 147 131 | Page1 977 Figure 1: Proposed Mackellar fleet Non-acid forming waste rock will be used to encapsulate the existing heap leach pads as well as any potentially acid forming waste from the pit. The use of the waste rock from the cutback to cover the heap leach pads saves considerable expense in closure activities later in the mine life.
