General Notes:

Data is reported to significant figures to reflect appropriate precision and may not sum precisely due to rounding.

Mineral Resources are reported inclusive of Ore Reserves. Estimates undertaken by Evolution include all exploration
and resource definition drilling information up to 31 December 2020 and have been depleted for mining to 31
December 2020.

1 Includes stockpiles

2 Ernest Henry Operation cut-off 0.9% CuEq

3 Red Lake cut-off is 3.3g/t Au except for Cochenour (3.0g/t Au) and HG Young (3.2g/t Au) deposits

5 The Mineral Resource for the Mt Carlton A39 underground deposit has been estimated using a AuEq (g/t) cut-off of 4.4g/t to enable quotation of this silver rich deposit as equivalent gold ounces.

This information is extracted from the ASX release entitled “Annual Mineral Resources and Ore Reserves Statement” released to the ASX on 17 February 2021.

The gold equivalent (AuEq) calculation accounts for silver recoveries determined from metallurgical test work and uses an assumed silver price of A$26/oz and gold price of A$2,000/oz as per the below equation.
AuEq=26/2,000*0.8203*silver grade (Silver price/Gold price*silver recovery*silver grade). It is the Competent Persons opinion that the assigned cut-off criteria satisfies the JORC Code requirement that the reported Mineral Resource meets reasonable prospects of eventual economic extraction and that the silver present within the A39 deposit can be economically recovered. 

Full details of the Ernest Henry Mineral Resources and Ore Reserves are provided in the report entitled “Glencore Resources and Reserves as at 31 December 2020” released 3 February 2021 and available to view at The Company confirms that the form and context in which the Competent Persons’ findings are presented have not been materially modified from the original market announcement. 

Evolution Mining has an economic interest earning rights to 100% of the revenue from future gold production and 30% of future copper and silver produced from an agreed area, and 49% of future gold, copper and silver produced from the Ernest Henry Resource outside the agreed area. The Ernest Henry Resource is reported here on the basis of economic interest and not the entire mine resource. The above reported figures constitute 77% of the total Ernest Henry gold resource.
