FORWARD LOOKING STATEMENT
These materials prepared by Evolution Mining Limited (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.

Ore Reserve has been updated for E42 Stage H Open Pit in line with 2022 corporate commodity price assumptions, updated modifying factors and allowing for depletion. All remaining 'Open Pit Continuation' Ore Reserves (OPC) are declared as per December 2021 Cowal Open Pit Ore Reserves. The OPC Ore Reserve will be updated at the completion of the OPC Feasibility Study ('FS'). Modifying factors to be updated during the FS include Mineral Resource, geotechnical, metallurgical, revenue and cost assumptions. To date, no fatal flaws have been identified during the FS. A materiality test was conducted on the impact of the change between the December 2021 and December 2022 Mineral Resource model on the OPC Ore Reserve, the change is expected to be less than 10%
3.Cowal Underground Ore Reserve has been optimised using a \$1,600/oz price assumption, economically tested at up to \$2,200/oz and considers updated modifying factors and depletion. The Cowal Underground Ore Reserve includes development material at an incremental cut-off grade of 0.55g/t Au
4.Red Lake Ore Reserve cut-off is 4.0g/t Au except for HG Young (3.0g/t Au) and Upper Campbell (2.5g/t Au)
-
Mungari Underground Ore Reserve cut-off varies from 2.2g/t Au to 3.8g/t Au and is dependent on specific deposits and varies between each underground mine taking into account location and costs
-
Mungari Open Pit Ore Reserves were optimised using a \$1,600/oz gold price assumption. The exceptions are the Paradigm and Castle Hill open pit operations which have been scheduled for production between 2023 and 2025 and have been optimised with a \$2,200/oz gold price assumption. Cut-offs vary by deposit from 0.57g/t Au to 0.74g/t Au and take into account location and costs

Ernest Henry Operations reported Ore Reserve estimate is based on the June 2022 Mineral Resource detailed in the 1 August 2022 ASX release titled "Material Increase in Ernest Henry Mineral Resource'. The applied cut-off grade of 0.75% copper equivalent ('CuEq') is 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/72.77 where; Au NSR = 41.71*Au - 0.04

Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary | |
|---|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or 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 representivity 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 done this would be relatively simple (eg '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. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information |

Diamond core drill holes are the primary source of geological and grade information for the resource at Ernest Henry Mine. Drilling has been completed between 1980 and 2022.A total of 1,169 holes were extracted from the acQuire database and 836 drill holes containing Cu assays and 835 holes containing Au assays were used in the Mineral Resource estimate. Reverse circulation (RC) drilling was completed to base of oxidation with some holes hosting diamond tails. The diamond core is routinely sampled to geological contacts and predominantly 2m intervals from ½ core over the entire length of the drill hole, producing approximately 5kg samples. Holes drilled from the surface and underground are oriented perpendicular to orebody mineralisation where possible. UG channel samples taken from chip sampling of development drives at 2m intervals are also used to help define mineralogical domains. Whilst they are not used directly in estimation, chip samples typically yield 4kg – 5kg masses. Samples undergo further preparation and analysis by ALS laboratories (Townsville and Brisbane), involving crushing to 2mm, riffle splitting and pulverising to 85% passing 75 microns. Of this material a 0.4g sample is prepared for analysis via aqua regia digestion and 50g for analysis via fire assay. |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
• • |
Drill types utilised in grade estimation are diamond core including HQ, NQ2 & NQ sizes yielding core diameters of 63.5mm, 50.6mm & 47.6mm respectively. Drill core is collected with a 3m barrel and standard tubing. Only selected drill holes have been oriented using an ezi mark orientation system for structural and geotechnical requirements. |
| 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. |
• • • |
Current practice ensures all diamond core intervals are measured and recorded for rock quality designation (RQD) and core loss. Core recovery through the ore portion of the deposit is high (>99.5%). No bias is observed due to core loss. |
| 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 has been logged, geologically and geotechnically. The geologic and geotechnical records are considered qualitative and quantitative with the following items being captured: Lithology, Texture, Alteration, Mineralisation, Structures – including veining & faults, Weathering, RQD, Photography of diamond core has captured approximately 60% of the data set. |

• Drill core is cut in half to produce an approximate 5kg sample using an automatic core saw, with one half submitted for assay, and the other half retained on site. Where core is oriented, it is cut on the core orientation line. • Diamond core and channel samples are predominantly sampled at 2m intervals. Samples are sent to ALS Townsville for crushing and pulverisation. Samples are crushed to 2mm, split via a riffle or rotary splitter and then pulverised using an LM5 mill to a nominal 85% passing 75 microns. A 0.4g sub-sample of pulverised material is taken for ICP analysis via aqua regia digestion and a 50g sub sample is taken for analysis via fire assay. The remaining pulverised sample is returned to site and stored for future reference. • Samples submitted to OSLS are crushed to 90% passing 2 mm, rotary split to 3.5kg (if required) and pulverised using an LM5 mill to 90% passing 75 microns. A 0.5g sub-sample is taken for base metal analysis via aqua regia digestion and determined by ICP. A 25g sub-sample is taken for analysis via fire assay. • Sub-sampling is performed during the sample preparation stage in line with ALS internal protocol. • Field duplicates are collected for all diamond core at a rate of one in every 15 samples and for channel sample at a rate of one in every 10 samples. • Comparison of field duplicates is performed routinely to ensure a representative sample is being obtained and that the sample size captures an adequate sample volume to represent the grain size and inherent mineralogical variability within the sampled material. • Samples are assayed at ALS Brisbane for a multi element suite using ME-ICP41, Cu-OG46 & MEOG46 methods, which analyses a 0.4g sample in aqua-regia digestion with an ICP-AES finish. Gold analysis is completed at ALS Townsville by fire assay on a 50g sample with an AA instrument finish. Analytical methods are deemed appropriate for this style of mineralisation. • Historic quality control procedures include the use of six certified standards (CRMs) as well as field duplicates inserted at 1:25 ratio for all sample batches sent to the ALS laboratory. • The quality assurance program includes repeat and check assays from an independent third-party laboratory as deemed necessary. • There have been no blanks used on the diamond core historic data set. The ALS laboratory provides their own quality control data, |

which includes laboratory standards and duplicates. • EHO currently uses five CRMs, pulverised and coarse blanks, field, crush and pulp duplicates to monitor sample preparation and analytical processes. The rate or insertion was 1:15 for CRMs, 1:15 for blanks within mineralised units and 1:30 in waste zones, Field duplicates were inserted at 1:15 while crush and pulp duplicates were at 1:25 samples. • Analysis of quality control sample assays indicate the accuracy and precision is within acceptable limits and suitable for inclusion in the underground resource estimate. |

| 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, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
• All diamond drill holes are logged remotely on a laptop utilising AcQuire software and stored digitally in an AcQuire database on a network server. • Drill holes are visually logged for copper content prior to sampling and assay. This visual assessment is used to verify assay data. • The strong correlation between copper and gold enables additional quality control checks to be enacted on returned assays. • Procedures have been developed to ensure a repeatable process is in place for transferring, maintaining & storing all drilling, logging and sampling data on the network server, which has a live upload to a local device and daily back up to an offsite device. • Following review of the historical dataset for the underground Resource, no adjustments have been made to any assay data. All files are reported digitally from ALS laboratories in CSV format, which is then imported directly into the Acquire database. Checks of the assay results in AcQuire and results returned from the laboratory are performed at the completion of each drilling & sampling campaign. Laboratory certificates for returned assays are stored for future reference and checks against values contained within the AcQuire database. |

| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
▪ Collar coordinates are picked up by EHO site surveyors using a Leica total station survey instrument. All underground excavations are monitored using the same instrument. ▪ The topography was generated from a LIDAR survey completed over EHM mining leases in 2018 with outputs in GDA94 coordinate system. ▪ A variety of downhole survey methods have been utilised in the underground resource, however 93% of the diamond drill holes have been surveyed using a gyroscopic instrument recording down hole survey data in 3m intervals. |
| Data spacing and distribution |
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. |
▪ All data points are reported in MGA94 zone 54. • Drill holes are variably spaced with the following broad resource classifications applied: • Between 30m x 30m and 40m x 40m for Measured • 60m x 60m for Indicated • 100m x 100m Inferred. • This drill hole spacing is considered sufficient given the deposit grade and geological continuity and Mineral Resource classification definitions as outlined in the 2012 JORC Code, which is also supported by historic reconciliation data from the mill. • Samples are weighted by length and density when composited to 2m in length for use in the estimation. |
| 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. |
• Holes drilled from the surface and underground are oriented perpendicular to orebody mineralisation and orebody bounding shear zones wherever possible. UG channel samples are oriented along the strike of orebody mineralisation and are conducted on a lateral 25m spacing, in line with sub-level mine excavations. • There has been no orientation bias recognised within the data used for the underground Resource estimate. |
| Sample security | The measures taken to ensure sample security |
• Diamond core samples are securely stored onsite prior to being despatched to the ALS laboratory in Townsville. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
• An external audit conducted in 2014 on the data management & QAQC procedures including drilling & sampling. These were found to be in line with industry standards. CSA Global completed a fatal flaw analysis of the Ernest Henry Mineral Resource estimate in July 2021 and only minor issues were identified. |

Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties • The EHM orebody was discovered by Western Mining Corporation Limited in 1991. The size and potential of the discovery became obvious with further drill definition following soon after, leading to a Feasibility Study and subsequently the open pit mine and mill. In 2006 a deep drilling campaign was initiated to explore the down dip extension of the deposit ultimately leading to the development of the current underground mining project.

▪ | The Ernest Henry Deposit is an Iron Oxide Copper Gold (IOCG) hosted within a sequence of moderately SSE-dipping, intensely altered Paleoproterozoic intermediate metavolcanic and metasedimentary rocks of the Mt Isa group. Copper occurs as chalcopyrite within the magnetite-biotite-calcite-pyrite matrix of a 250 x 300 m pipe like breccia body. The breccia pipe dips approximately 40 degrees to the South and is bounded on both the footwall and hanging wall by shear zones. The main orebody starts to split from the 1575 level into a South-East lens, and from the 1275 level into the South-West lens. Both lenses are separated from the main orebody by waste zones, termed the Inter-lens and South-West Shear Zone, respectively. The orebody is open at depth. |
