PRODUCTION TARGET

Mungari Production Target and relevant proportions of Mineral Resources and Ore Reserves underpinning the Production Target

The Mungari Production Target of 1.9Moz to 2.7Moz between FY24 and FY38 comprises 3% Proved Ore Reserves, 49% Probable Ore Reserves, 19% Indicated Mineral Resources, 18% Inferred Mineral Resources and 11% Exploration Targets. 1

Cautionary statement concerning the proportion of Inferred Mineral Resources

There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised.

Cautionary statement concerning the proportion of Exploration Targets

Of Mungari's 1.9Moz to 2.7Moz production target, 11% is comprised of an Exploration Target. The potential quantity and grade of this Exploration Target is conceptual in nature and there has been insufficient exploration to determine a Mineral Resource and there is no certainty that further exploration work will result in the determination of Mineral Resources or that Production Target itself will be realised. See ASX release titled 'Mungari Mine Life Extended to 15 Years at 18 to 20% Lower AISC', released 5 June 2023 and available to view at www.evolutionmining.com.au for further information on the Exploration Target.

Material Assumptions

The material assumptions on which the Mungari Production Target is based are presented in the ASX release titled 'Mungari Mine Life Extended to 15 Years at 18 to 20% Lower AISC' dated 5 June 2023 and available to view at www.evolutionmining.com.au

Production Target Competent Persons' Statement

The Estimated Mineral Resources and Ore Reserves underpinning the Mungari Production Target have been prepared by Competent Persons in accordance with the requirements in Appendix 5A (JORC Code).

The Company confirms that all material assumptions underpinning the production targets and forecast financial information derived from the production targets in the 5 June 2023 release continue to apply and have not materially changed.

  1. Proportions quoted are based on the material classifications of the entire Production Target and is inclusive of material attributable to the East Kundana Joint Venture

FORWARD LOOKING STATEMENT

These materials prepared by Evolution Mining Limited ('Evolution' or 'the Company') include forward looking statements. Often, but not always, forward looking statements can generally be identified by the use of forward looking words such as 'may', 'will', 'expect', 'intend', 'plan', 'estimate', 'anticipate', 'continue', and 'guidance', or other similar words and may include, without limitation, statements regarding plans, strategies and objectives of management, anticipated production or construction commencement dates and expected costs or production outputs.

Forward looking statements inherently involve known and unknown risks, uncertainties and other factors that may cause the Company's actual results, performance and achievements to differ materially from any future results, performance or achievements. Relevant factors may include, but are not limited to, changes in commodity prices, foreign exchange fluctuations and general economic conditions, increased costs and demand for production inputs, the speculative nature of exploration and project development, including the risks of obtaining necessary licenses and permits and diminishing quantities or grades of reserves, political and social risks, changes to the regulatory framework within which the Company operates or may in the future operate, environmental conditions including extreme weather conditions, recruitment and retention of personnel, industrial relations issues and litigation.

Forward looking statements are based on the Company and its management's good faith assumptions relating to the financial, market, regulatory and other relevant environments that will exist and affect the Company's business and operations in the future. The Company does not give any assurance that the assumptions on which forward looking statements are based will prove to be correct, or that the Company's business or operations will not be affected in any material manner by these or other factors not foreseen or foreseeable by the Company or management or beyond the Company's control.

Although the Company attempts and has attempted to identify factors that would cause actual actions, events or results to differ materially from those disclosed in forward looking statements, there may be other factors that could cause actual results, performance, achievements or events not to be as anticipated, estimated or intended, and many events are beyond the reasonable control of the Company. Accordingly, readers are cautioned not to place undue reliance on forward looking statements. Forward looking statements in these materials speak only at the date of issue. Subject to any continuing obligations under applicable law or any relevant stock exchange listing rules, in providing this information the Company does not undertake any obligation to publicly update or revise any of the forward-looking statements or to advise of any change in events, conditions or circumstances on which any such statement is based.

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

  1. Includes stockpiles

  2. Open Pit Mineral Resource reporting shells were optimised using a gold price of \$AU 2,500/oz. All material which meets or exceeds the cut-off grade within the developed pit shells is included in the reported Mineral Resource

  3. Underground Mineral Resource reporting shapes were developed using a gold price of \$AU 2,500/oz; all material which falls within optimized mining shapes inclusive of internal waste or low grade is included in the reported Mineral Resource

  4. Ernest Henry Operations reported Mineral Resources are reported within an interpreted 0.7% Cu mineralised envelope which includes internal waste and low-grade material

  5. Marsden Mineral Resource is reported based on an NSR value calculation that considers mining and processing costs, metallurgical recoveries, royalties, transport and refining costs into account. The NSR produces a value cut-off (by block) that is approximately equivalent to a 0.2g/t gold cut-off

  6. Northparkes Open Pit Mineral Resource includes all material within designed pit shells above an economic cutoff grade; cut-off grades are 0.65g/t Au for E44 and 0.34% CuEq for E31 and have been calculated based on US\$3.30/lb copper, US\$1,350/oz gold and 0.73 AUD:USD conversion rate

  7. Northparkes Underground Mineral Resource metal price and exchange rate assumptions vary by project, reporting shapes were developed using price assumptions between US \$1.69 - US\$3/lb copper, US\$660 - US\$1350/oz gold and an AU\$:US\$ conversion rate of 0.73 - 0.75. Northparkes underground cut-off grades are reported within 0.4% Cu grade shells with the exception of E22 using A\$18NSR, E26 L2 using A\$40NSR and MJH using A\$25NSR

  8. The reported Mineral Resource shown for Northparkes is exclusive of Ore Reserves. The values reported reflect the 80% portion attributable to Evolution Mining only. Triple Flag Metal Purchase and Sale Agreement purchased 67.5% of gold production capped at 630koz gold, followed by 33.75% gold production for the remaining life of mine with ongoing payments equal to 10% of the spot metal price delivered – 41koz delivered under this agreement to 31/12/2023

  2. Cowal Open Pit Ore Reserves are reported with respect to the declared Mineral Resource from December 2023. E42, E41, E46 and GRE Open Pit Ore Reserves are supported by the OPC Feasibility Study completed in June 2023 that demonstrates the proposed mine plans and schedules are economically viable. E46 and GR were optimised using a A\$1,800/oz gold price assumption. E41 and E42 Stage I were optimised using gold price assumptions of \$1,584/oz and \$1,944/oz respectively. The Cowal Open Pit Ore Reserves are economic viable at the Evolution life of mine gold price assumption of A\$2,650/oz.

  3. Cowal Underground Ore Reserve has been optimised using a A\$1,800/oz price assumption, economically tested at up to A\$2,650/oz and considers updated modifying factors and depletion. The Cowal Underground Ore Reserve includes development material at an incremental cut-off grade of 0.6g/t Au

  4. Ernest Henry reported Ore Reserve estimate is based on the December 2022 Mineral Resource detailed in the ASX Release titled "Annual Mineral Resources and Ore Reserves Statement" dated 16 Feb 2023 and available to view at www.evolutionmining.com.au . The applied flow model cut-off grades of 0.50 % and 0.75% copper equivalent ('CuEq') are determined through an economic evaluation process which considers the Net Smelter Return (NSR) and operating costs. The utilised copper equivalent equation is: CuEq = Cu + Au NSR/56.4 where; Au NSR = 38.5 * Au - 0.047

  5. Mungari Open Pit Ore Reserve cut-off varies from 0.39g/t Au to 0.65g/t Au; the weighted average cut-off is 0.50g/t Au. Gold prices between A\$1,800 and A\$2,400/ounce were used to calculate cut-off grades for Open Pit Ore Reserve estimate

  6. Mungari Underground Ore Reserve cut-off varies from 2.80g/t Au to 3.63g/t Au; the weighted average cut-off is 3.19g/t Au. Gold price of A\$1,800 was used to calculate cut-off grades for the Underground Ore Reserve estimate

  7. Red Lake Ore Reserve has been evaluated using an A\$1800/oz price, except for the Upper Campbell and Upper Red Lake regions which have been re-reported this year using previous price assumptions of A\$1600/oz. In 2024 a 'Hill of Value' study is scheduled to optimize the mine plan and cutoff criteria throughout the operation

  8. The Marsden Ore Reserve has been reported using a 'Net Smelter Return' (NSR) cut-off which takes into account ore haulage from Marsden to Cowal, ore processing costs at Cowal, general and administration costs, treatment and refining costs, concentrate costs, metallurgical recoveries, metal payabilities, metal prices, and royalties.The breakeven NSR value equates approximately to a 0.3g/t Au cutoff. The Ore Reserve estimate was developed using a A\$1,350 per ounce gold price and a A\$6000/t copper price

  9. Northparkes Ore Reserve is based on Pre-Feasibility & Feasibility studies completed at different times using differing price assumptions. Copper price assumptions vary between US\$ 2.75-3.77/lb, Gold price assumptions vary between US\$ 1250-1750/oz and AUD:USD exchange rates used were between 0.73-0.78. The values reported reflect the 80% portion attributable to Evolution Mining only.
