1 EXECUTIVE SUMMARY
Exploration activity in FY22 Q1 across the East Kundana Joint Venture focused on confirming grade continuity on the main mineralised K2 structure below current development at Rubicon and between the declines in the area connecting Rubicon and Pegasus (see Figure 1). Exploration being defined by Drill Targeting or Resource Targeting designations (Table 1).
Drilling continued to define ore body continuity and delineate extensions of mineralisation at Pode and Hera which are each situated in the hangingwall of the K2 structure. Several holes intercepted mineralisation outside the Pode and Hera wireframes keeping open the possibility of modest resource expansion downdip on both structures.

EXPLORATION ACTIVITY
1.1 Rubicon-Hornet-Pegasus (RT/DT)
A total of 65 diamond drill holes for 12,359 metres were completed between 1[st] July 2021 and 30[th] September 2021 (see Table 2). Underground exploration drilling focused on Pode, Startrek and Nugget prospects, with a small amount of drilling targeting Pegasus Bell and Hera prospects.
Underground drilling targeting Hera and Pode southerly strike extensions was conducted from Pode 6011 SP (see Figure 2). Underground exploration drilling targeting Startrek was conducted from Rubicon 6195 ODS and Hornet 6205 ODS (see Figure 3). Underground exploration drilling targeting Pegasus Bell was conducted from Pegasus 5880 ACC SP (see Figure 4), and drilling targeting Nugget was conducted from Nugget 5960 DD, Nugget 5975 DD, Rubicon 5938 SP and Rubicon 5935 SP (see Figure 5).

2 EXPLORATION RESULTS
2.1 Hornet-Rubicon-Pegasus
2.1.1 Hornet
Eight exploration holes targeting the F18 Hornet alteration lode returned intercepts showing significant gold mineralisation during the quarter (Table 3 and Figure 6). All holes targeting the F18 structure intercepted mineralisation at target depth, with several holes intercepting alteration style mineralisation in the hanging-wall of the F18 structure.

2.1.2 Nugget
Five holes targeting the Rubicon Nugget structure returned intercepts showing significant gold mineralisation during the quarter (see Table 3). Drilling from Rubicon 5938 SP and Rubicon 5935 SP intercepted the Nugget structure at target depths, increasing the mineralisation footprint down-dip and along strike (see Figure 7). Drilling conducted from Rubicon RAW returned significacant assays for a brecciated vein system in-line with the projected Nugget plane (see Figure 8).

2.1.3 Startrek
Fourteen holes targeting the Startrek mineralisation returned significant mineralisation including a well laminated quartz vein intercepted in STKRT20082 which returned 0.5m etw grading 20.9g/t Au (see Table 4 and Figure 9). Intercepts were broadly in-line with the conceptual Startrek mineralisation model.
The Startrek mineralisation occurs in the footwall of the K2 structure and consist of several stacked mineralised lodes delineated in wide-spaced drilling. Drilling has intersected mineralisation at various locations in the footwall of Rubicon-Hornet-Pegasus over a strike length of approximately one kilometre. Significantly more drilling will be required to understand continuity of mineralisation along strike and downdip of the Startrek mineralised trend.

| 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). |
• 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 20cm and a maximum width of 120cm. • 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. |

• 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. • Diamond drilling the 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 drillingrates or reduce |

• 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 -6mm 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. |

| 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 finalassay datareported by thelaboratory. |
| 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. |

Section 2 Reporting of Resource Development Results
(Criteria listed in the preceding section also apply to this section.)
| Mungari – RHP Section 2 Reporting of Resource Development Results | Mungari – RHP Section 2 Reporting of Resource Development Results | |
|---|---|---|
| Criteria | Explanation | Commentary |
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. •The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• Diamond holes mentioned in this report are located within the M16/309 and M15/993 Mining leases held by The East Kundana Joint Venture (EKJV). The EKJV is majority owned and managed by Evolution Mining (51%). The minority holding in the EKJV is held by Tribune Resources Ltd (36.75%) and Rand Mining Ltd (12.25%). • M16/309 is subject to two royalty agreements; however, neither of these is applicable to the Prospects described in this report. The agreements concerned are the Kundana‐Hornet Central Royalty and the Kundana Pope John Agreement No. 2602‐13. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Underground drilling on the Raleigh and Hornet-Rubicon- Pegasus mines extends the mineralised trends from older drilling including that of previous operators of those mines including Barrick Gold, Placer Dome Asia-Pacific, Aurion Gold, Goldfields Limited, Northern Star Resources and otherpredecessors. |
| 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. • Raleigh 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. • The Hornet-Rubicon-Pegasus mineralisation consists primarily of high-grade laminated vein hosted gold on the K2 plane of the Zuleika shear with additional mineralisation on associated lower order structures. The Falcon target is a related mineralised zone in the hangingwall to Pegasus and between the two main Zuleika structures, theK2and Strzeleckistructures. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collar o elevation or RL of the drillhole collar o dip and azimuth of the hole |
• Refer to the drill hole information table in the Appendix of this report. |

| Data aggregation methods |
•In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low- grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. •The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• All drill results are reported as aggregates across the target zone. • No metal equivalent values are used. |
| Relationship between mineralisatio n widths and intercept lengths |
•These relationships are particularly important in the reporting of Exploration Results. •If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. •If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘downhole length, true width not known’) |
• The orientation of target structures is well known for all in- mine exploration targets and true widths can be accurately calculated and are reported accordingly. • Both the downhole width and true width have been clearly specified when used. • The assay results are reported as down hole intervals with an estimate of true width provided in Appendix. |
| Diagrams | •Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole. |
• Drill hole location diagrams and representative sections of reported exploration results are provided either below or in the body of this report. |
| 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, |
• No other material exploration data has been collected for this drill program. |
