Forward looking statement
==> picture [64 x 43] intentionally omitted <==
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.
Non-IFRS financial information
Investors should be aware that financial data in this presentation includes ‘non-IFRS financial information' under ASIC Regulatory Guide 230 Disclosing non-IFRS financial information published by ASIC and also ‘non-GAAP financial measures' within the meaning of Regulation G under the U.S. Securities Exchange Act of 1934. Non-IFRS/non-GAAP measures in this presentation include gearing, sustaining capital, major product capital, major mine development, production cost information such as All-in Sustaining Cost and All-in Cost. Evolution believes this non-IFRS/non-GAAP financial information provides useful information to users in measuring the financial performance and conditions of Evolution. The non-IFRS financial information do not have a standardised meaning prescribed by the Australian Accounting Standards (‘AAS’) and, therefore, may not be comparable to similarly titled measures presented by other entities, nor should they be construed as an alternative to other financial measures determined in accordance with AAS.

|---|---|---|
| Criteria | Explanation | Commentary |
| Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are material to the Public Report. • In cases where ‘industry standard’ work has been completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. ▪ Sampling was completed using diamond drill core (DD). ▪ Diamond core was transferred to core trays for logging and sampling. Half core or full core samples were nominated by the geologist from HQ or NQ diamond core, with a minimum sample width of 10cm and a maximum width of 100cm. ▪ Samples were transported to various analysis laboratories in Kalgoorlie for preparation by drying, crushing to <3mm, and pulverizing the entire sample to <75μm. ▪ 300g Pulp splits were analysed by ALS Global Laboratories in Kalgoorlie, Adelaide, and Perth for 40-50g Fire assay charge and AAS analysis for gold. |
||
Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). ▪ For underground drilling, NQ2 (50.6mm) diameter core was used. ▪ Core was orientated using an electronic ‘back-end tool’ core orientation system. |

| Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. ▪ All diamond core was orientated and measured during processing and the recovery recorded into the drill-hole database. The core was reconstructed into continuous runs on a cradle for orientation marking. Hole depths were checked against the driller’s core blocks. ▪ Inconsistencies between the logging and the driller’s core depth measurement blocks are investigated. Core recovery has been acceptable. ▪ The diamond drilling contractors adjust their rate of drilling and method if recovery issues arise. All recovery is recorded by the drillers on core blocks. This is checked and compared to the measurements of the core by the geological team. Any issues are communicated back to the drilling contractor ▪ Measures taken to maximise sample recovery include instructions to drillers to slow down drilling rates or reduce the coring run length in less competent ground. ▪ Analysis of drill sample bias and loss/gain was undertaken with the Overall Mine Reconciliation performance where available. |
||
| Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. • The total length and percentage of the relevant intersections logged. ▪ All diamond core is logged for regolith, lithology, veining, alteration, mineralisation and structure. Structural measurements of specific features are taken through oriented zones. All logging is quantitative where possible and qualitative elsewhere. A photograph is taken of every core tray (wet). |
||
Sub-sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. ▪ All diamond core that was half-core sampled was cut longitudinally with an automated core saw. ▪ Sample preparation was conducted by ALS Global, commencing with sorting, checking and drying at less than 110°C to prevent sulphide breakdown. Samples are jaw crushed to a nominal 3mm particle size. The entire crushed sample is then pulverized to 90% passing 75μm, using a bowl or ring-mill pulveriser. 300g Pulp subsamples are then taken with an aluminium scoop and stored in labelled pulp packets. ▪ Grind checks are performed at both the crushing stage (3mm) and pulverising stage (75μm), requiring 90% of material to pass through the relevant size to ensure consistent sample preparation. |

| Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments etc. the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. ▪ A 40-50g fire assay charge is used with a lead flux, dissolved in the furnace. The prill is totally digested in HCl and HNO3 acids before Atomic Absorption Spectroscopy (AAS) determination for gold analysis. This method ensures total gold is reported appropriately. ▪ No geophysical tools were used to determine any element concentrations ▪ Certified Reference Materials (CRMs) are inserted into the sample sequence randomly at a rate of 1 per 20 composite samples to ensure correct calibration. Any values outside of 3 standard deviations are scrutinised and re-assayed with a new CRM if the failure is deemed genuine. ▪ Blanks are inserted into the sample sequence at a rate of 1 per 20 composite samples. Failures above 0.1g/t are scrutinised, and re-assayed if required. New pulps are prepared if failures remain. ▪ All sample QAQC results are assessed by geologists to ensure the appropriate level of accuracy and precision when the results have been returned from the laboratory. |
||
| Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. ▪ All significant intersections are verified by the project geologist and senior geologist during the drill hole validation process. ▪ Half core and sample pulps are retained at Mungari if further verification is required. ▪ The twinning of holes is not a common practice undertaken at Mungari. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. ▪ All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained at the technical mining offices. ▪ No adjustments or calibrations have been made to the final assay data reported by the laboratory. |

| Location of data points • Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. ▪ All collars for underground drilling are located in the local mine grid by a mine surveyor using a laser theodolite. ▪ Mine surveyors update control points underground as mine development continues. All drillhole collars are surveyed with locating two control points as required for precision of instrumentation. |
||
| Data spacing and distribution • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. ▪ The nominal drill spacing for Exploration drilling is 80m x 80m or wider and for Resource Definition is 40m x 40m or in some areas 20m x 20m. This spacing includes data that has been verified from previous exploration activities on the project. ▪ Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. ▪ Sample compositing was not applied due to the often-narrow mineralised zones. ▪ Compositing downhole within each estimation domain using a variable length compositing technique to a maximum length of one metre. The target composite length aligns with the dominant sample length of the raw sample data. |
||
Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. ▪ All drilling both underground and surface is oriented as close as practical to perpendicular to the target structures. The orientation of all in-mine target structures is well known and drill holes are only designed where meaningful intercept angles can be achieved. ▪ No sampling bias is considered to have been introduced by the drilling orientation. |
||
| Sample security • The measures taken to ensure sample security. ▪ Prior to submission samples are retained on site and access to the samples is restricted. Collected samples are dropped off at the respective commercial laboratories in Kalgoorlie. The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. |
||
| Audits or reviews • The results of any audits or reviews of sampling techniques and data. ▪ A Lab audit with ALS Global in Kalgoorlie was completed on the 6th of October 2023. No actions were issued because of the audit. ▪ A Lab audit with Bearu Vertias was completed on 10 October 2023. No actions were issued because of the audit. |

||
Geology • Deposit type, geological setting and style of mineralisation. ▪ The Kundana camp is situated within the Norseman-Wiluna Greenstone Belt, in an area dominated by the Zuleika Shear Zone, which separates the Coolgardie domain from the Ora Banda domain. The Zuleika Shear Zone in the Kundana area comprises multiple anastomosing shears the most important of which are the K2, the K2A and Strzelecki Shears. ▪ Xmas and Xmas HW (Genesis) mineralisation is hosted on the Strzelecki Structure. Strzelecki mineralisation consists of very narrow, very high-grade mineralisation on a laminated vein hosted in the camp-scale Strzelecki Shear which abuts a differentiated mafic intrusive, the Powder Sill Gabbro against intermediate volcanoclastic rocks (Black Flag Group). A thin ‘skin’ of volcanogenic lithic siltstone-sandstone lies between the gabbro and the Strzelecki shear. Being bound by an intrusive contact on one side and a sheared contact on the other, the thickness of the sedimentary package is highly variable from absent to about forty metres true width. |

| Criteria | Explanation | Commentary |
| Balanced reporting • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. ▪ All Exploration and Resource Definition results have been reported in the Drill Hole Information Summary in the Appendix of this report. |
||
| Other substantive exploration data • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. ▪ No other material exploration data has been collected for this drill program. |
||
| Further work • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or largescale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. ▪ Further work includes updating the geological model, for the drilling results received and updating the Mineral Resource estimate. An economic evaluation will be completed utilising a Mine Shape Optimiser function. |

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 Open Pit 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.
-
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
-
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
-
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
-
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
-
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
-
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$6000/t copper price
-
Northparkes Ore Reserve is based on Pre-Feasibility & Feasibility studies completed at different times using differing price assumptions. Copper price assumptions vary between US$ 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.
