Full Summary

Aeris Resources Limited (ASX: AIS) is pleased to announce a Maiden Open Pit Ore Reserve Estimate for its Constellation Project, located in the Cobar Basin Region of New South Wales, approximately 45 kilometres north-east of the Tritton Processing Plant. The Maiden Ore Reserve Estimate has been derived from the recently reported Constellation Mineral Resource Estimate and is based on the technical and economic analyses completed as part of Pre-Feasibility Studies for the initial open pit mining options. The estimate reports only mineralisation classified as Indicated Resource in accordance with the JORC Code (2012 Edition). The Maiden Open Pit Ore Reserve Estimate is 2.3 Mt @ 2.0% Cu, 0.6 g/t Au, 3 g/t Ag containing 47 kt Cu, 49 koz Au, and 228 koz Ag. The pit design underpinning the Ore Reserve includes 0.6Mt of Inferred Resource @ 3.2% Cu, 0.5 g/t Au, 3 g/t Ag containing an estimated 20 kt Cu, 10 koz Au, and 62 koz Ag. This material is not included in the Ore Reserve and is planned to be drilled prior to mining with the objective to upgrade this material into Indicated status. Further studies are underway to assess the deeper portions of the Constellation mineralisation for potential underground mining opportunities.

Outlook

Further studies are underway to assess the deeper portions of the Constellation mineralisation for potential underground mining opportunities.
