Announcement summary: Evolution Mining Limited (ASX:EVN) (“Evolution”) is pleased to release an updated Mineral Resource estimate at Ernest Henry. The new model includes 30,159 metres of new drilling from 119 drillholes for a total aggregate increase of 28% in contained copper and 24% in contained gold, along with upgrades to the Mineral Resource classifications. The update includes all drilling results to 31 May 2022 and the model is depleted for mining to June 30, 2022. The Mineral Resource was estimated into an interpreted 0.7% copper grade shell consistent with the previous estimate completed by Glencore. The new Mineral Resource estimate is being used to inform the Mine Extension Pre-feasibility study (PFS) due for completion by December 2022. The study will benefit from a significant resource increase above the 1,200mRL as well as growth below the 1,200mRL. The increased confidence in ore body geometry and grade distribution has resulted in an 82% addition to the Measured resource category and a 19% addition to the Indicated category. Two surface rigs are continuing a program of infill drilling below the 1,200mRL.
