Announcement PDF 29 October 2024 ASX/MEDIA RELEASE ADDENDUM TO 2024 ANNUAL REPORT Aeris Resources Limited (Aeris) (ASX:AIS) provides this addendum in relation to its 2024 Annual Report (Annual Report) announced on 25 October 2024. The purpose of this addendum is to provide a summary of the material changes in mineral resource and ore reserve holdings for the current period against those holdings from the prior period as well as an update to include additional technical disclosures required by the ASX Listing Rules (Listing Rules). Resources and Reserves The Mineral Resource and Ore Reserve estimates are reported in accordance with the guidelines of the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (“JORC 2012”). The estimates are reported at 31 December 2023. The Group Base Metals Mineral Resource has been estimated to contain 49.3 million tonnes grading 1.7% copper, 2.2% zinc, 0.6g/t gold and 24g/t silver for 822 thousand tonnes of copper metal, 1,065 thousand tonnes of zinc metal, 913 thousand ounces of gold metal and 37,990 thousand ounces of silver metal. Changes to the annual 31 December 2023 Group Base Metals Mineral Resource figures in comparison to the annual 31 December 2022 figures include the following:  Tritton Operations tonnage and contained copper metal decreased by 2.5Mt and 27kt, respectively, mainly due to mining depletion and reinterpretation of the Tritton, Murrawombie, Budgerygar and Avoca Tank deposits.  Jaguar Operations tonnage contained copper and zinc metal increased by 0.75Mt, 22kt Cu and 26kt Zn respectively, primarily due to the addition of the Jaguar Deposit.  North Queensland Operations tonnage has remained constant based on mine depletion at Mt Colin replaced by additional tonnes from an updated Barbara Mineral Resource estimate.  Stockman Project Mineral Resource increased by 1Mt, mainly due to a revised interpretation and Net Smelter Return (NSR) calculation. The Group Gold Mineral Resource has been estimated to contain 4,900 thousand tonnes grading 3.4g/t gold and 4g/t silver for 519 thousand ounces of gold metal and 664 thousand ounces of silver metal. The reported mineral resource remained constant for the reporting period, with mining depletion offset by resource additions. 1|P a g e ABN 30 147 131 | Page1 977 The Group Base Metals Ore Reserve has been estimated to contain 13.75 million tonnes grading 1.8% copper, 3.7% zinc, 0.8g/t gold and 30g/t silver for 245 thousand tonnes of copper metal, 508 thousand tonnes of zinc metal, 367 thousand ounces of gold metal and 13,619 thousand ounces of silver metal. Changes to the annual 31 December 2023 Group Base Metal Ore Reserve in comparison to the annual 31 December 2022 figures include the following:     Tritton Ore Reserve tonnage and copper metal decreased by 1.2Mt and 14kt respectively, predominately due to mining depletion at Tritton and Murrawombie and the remainder due to an updated mineral resource estimate for Avoca Tank that contains a larger portion of Inferred resource compared to the model used as the basis for the December 2022 estimate. North Queensland (Mt Colin) Ore Reserve tonnage decreased by 0.2Mt, predominately due to mining depletion. The Jaguar Ore Reserve has not been updated since the previous reporting period (31 December 2022). Operations were suspended at Jaguar in September 2023, and the mine was placed on care and maintenance pending restart studies (refer to ASX Announcement “Corporate Update and FY24 Guidance” dated 2 August 2023). Production in 2023 was 233kt @ 1.2% Cu, 4.5% Zn, 0.6g/t Au and 52g/t Ag. Ore Reserve depletion over the same period was 113kt @ 1.4% Cu, 7.3% Zn, 0.8g/t Au and 78g/t Ag. No change to the Stockman Project Ore Reserve. The Group Gold Ore Reserve has been estimated to contain 360 thousand tonnes grading 3.4g/t gold for 39 thousand ounces of gold metal. The annual Group Gold Metal Ore Reserve changes are predominately due to mining depletion. 2|P a g e Notes:  Mineral Resource figures are reported using a variety of cut-off criteria suitable for each deposit.  Discrepancy in summation may occur due to rounding.  A detailed description for each Mineral Resource estimate can be referred from ASX Announcement “Group Mineral Resource and Ore Reserve Statement” dated 17th June 2024. 3|P a g e ABN 30 147 131 | Page1 977 Notes:  Ore Reserve figures are reported using a variety of cut-off criteria suitable for each deposit.  Discrepancy in summation may occur due to rounding.  A detailed description for each Mineral Resource estimate can be referred from ASX Announcement “Group Mineral Resource and Ore Reserve Statement” dated 17th June 2024.  The Jaguar Ore Reserve has not been updated since the previous reporting period (end December 2022).
