Strike of Main Zone Extended South by 80m with 14.9m @ 3.84 g/t Au within the Open Pit Footprint

HIGHLIGHTS

• 14.9m @ 3.84 g/t Au from 143.1mdh , including 0.98m @ 30.6 g/t Au from 147.9mdh , intersected in SDH25-026.

• Main Zone strike extended south by 80m , beyond the current ~400m strike length defined in the MRE.

• Resource definition drilling commenced in December 2025 to test the southern extension of the ~400m strike Main Zone, which hosts the highest-grade domains in the current MRE block model and is interpreted to plunge south parallel to the Hong Kong Lode.

• Visible gold identified 40m immediately along strike and down plunge of SDH25-026.

• Geological reinterpretation indicates up to 500m of additional southern strike potential , of which the majority remains largely untested. More than 200m of this interpreted strike extension lies within the current pit optimisation shell.

• A budget has been approved for a 7,800m Phase 1 drilling program (18 holes) targeting the southern strike extension of the Main Zone and the recently identified eastern sheeted vein zone; seven holes completed to date, with assays expected in early Q2 2026.

Executive Chair, Ashley Pattison stated:

“Extending the Main Zone a further 80 metres south of the current 400 metre resource strike has important implications for the overall scale of mineralisation at Spring Hill. It reinforces our view that this is a growing system within what is already the highest-grade area of the resource.

Importantly, this intercept sits within our existing pit optimisation shell and was previously modelled as waste due to a lack of drilling. From a mining perspective, bringing additional mineralisation into the current pit shell has the potential to directly enhance open pit inventory and project economics.

Our work indicates the Main Zone may extend up to a further 500 metres to the south, broadly parallel to the Hong Kong Lode. The proximity of these two lodes presents a compelling opportunity for increasing the scale of operations and improving mining efficiencies over time.”

PC Gold Ltd (ASX: PC2) (“PC Gold” or “the Company”) is pleased to advise that extensional drilling to the south of the existing MRE boundary has discovered two new zones of mineralisation, with the first hole returning a wide zone of high-grade gold outside of the recently completed resource drilling on the Hong Kong and Macau lodes.

SDH25-026 targeted the southern extension of the Main Zone, located east of the Hong Kong Mineralised domain, and returned an interval of 14.9m @ 3.84 g/t Au from 143.1m, including 0.98m @ 30.6 g/t Au from 147.9m (See Figures 1 & 2).

This intercept is located approximately 100m along strike from the last drill hole forming the MRE on the Main Zone with the Phase 1 target zone illustrated in Figures 1 and 2 below.

Cautonary Statement:

Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The Company expects to receive the laboratory analytical results of the recent core samples (including MS010 & MS011) in early Q2 2026

The southern extension drilling is ongoing, with seven holes completed out of an eighteen-hole program. Importantly, visual gold has been identified in two drill holes located down plunge of SDH25-026 (See Figure 1, 3 & 4). MS-010 and MS-011 intercepted multiple intervals of coarse visible free gold associated with quartz-carbonate-chlorite breccias and sheeted veins with pyrite and arsenopyrite (See plates 3 & 4).

The visible gold identified confirms the plunging nature of the gold mineralisation in the southern Main Zone target. The drilling section containing MS-10 and MS-011 is a further 40m along strike from the high-grade intercept reported in SDH25-026 (Figure 3). Currently MS-006 is in progress, drilling directly beneath SDH25-026. MS-001 and MS-004 have been drilled but not logged, as geotechnical drill holes were prioritised as a key component of the ongoing Pre-Feasibility Study. The geotechnical program is now complete and logging and cutting of the remainder of the Main Zone Southern Extension program will continue.

The Main Zone Southern extension target has had limited drill testing to date despite being the highest-grade mineralisation in the current MRE. Following re-interpretation of the stratigraphy at Spring Hill by the new PC Gold technical team, the analysis identified what appears to be a spatial correlation between two stratigraphic units and the plunge of the Main Zone. One wildcat drillhole was completed across the strike extent, being SDH25-026.

Additionally, it is thought that the relatively steeply plunging nature of the mineralisation meant that two drill holes completed in 2022 drilled over the top of the high-grade plunging target.

In the current program, SDH25-026 was drilled on the same drill pad as 22HK005 but at a steeper angle and has successfully intersected the reported high-grade interval of 14.91m @ 3.84 g/t Au in the correct lithological unit. These latest drill results validate the updated geological interpretation of the West Lodes and provide confidence in the remainder of the drill program at the West Lodes southern extension.

The Main Zone is comprised of three steeply dipping zones of sheeted veins and large individual quartz reefs located in the hinge zone of the main Spring Hill Anticline. Typical widths range from 10-20m wide each and commonly widen where the steeply dipping zone intersects with the interpreted anticline. The high-grade material appears to plunge to the south at a similar rate to the Hong Kong zone with highest grades confined within a package of dominant siltstones and mudstones and a lower package of dominant greywacke with minor interbedded siltstone and tuff.

U38/460 Stirling Hwy, Peppermint Grove WA 6011 Australia e. admin@pcgold.com.au t. 08 6313 3996

==> picture [79 x 81] intentionally omitted <==

The mineralisation style is characterised by a well-developed quartz vein system, including sheeted and massive veins, locally brecciated and laminated. Alteration is dominated by carbonate and chlorite with occasional biotite alteration in greywacke. Mineralisation consists of abundant pyrite and arsenopyrite, occurring as coarse disseminations, veinlets and blebs and within sheeted and massive quartz veins. Occurrences of visible gold are noted, particularly in thick sheeted and massive quartz veins, commonly spatially associated with arsenopyrite. Quartz breccias locally grade into massive veins 1- 5m thick and host free gold. The host sequence is interpreted as lower greywacke with interbedding of siltstone and tuff bands.

Strategic Rationale for Targeting

The Main Zone domains have an average grade of 1.2 g/t Au and 1.1 g/t Au respectively in the current MRE. These domains have the highest average grade domains in the block model with volumetric significance. Targeting shallower, high-grade material has a significant impact on the project because the material is mined early in the mine plan when capital expenditure is commonly highest and Net Present Value (NPV) of cash flows are less discounted.

The drill program designed at the Main Zone southern extension mainly sits within the existing pit optimisation shell but is currently classified as waste. Any mineralisation identified in the shallower portions of these drill holes should be mined as part of the current open pit mine plan and also lead to a reduction in the strip ratio and an increase in contained gold in the open pit mine plan.

The revised interpretation is that the Main Zone plunges to the south at the same rate and extent as the Hong Kong sheeted vein system. Any mineralisation that is economic and mined will be sitting on the same elevation only 100-150m away from Hong Kong. Whilst beneficial for increasing total Resources, we will be targeting additions to the Main Zone also as potential UG targets that may significantly increase ounces per vertical meter, creating substantial cost efficiencies when UG mining commences at the southern end of the MRE in the longer term.

Next Steps

• Drilling of the Phase 1 program is ongoing with 7 drillholes completed out of a Phase 1 drill program of 18 holes for a total of 7,800m. One diamond rig to remain drilling this target.

• All resource definition holes in the Hong Kong and Macau zones have been cut and dispatched for assay. The Main zone south drill holes will be prioritised for cutting and dispatch to the lab for assay. Assay results for this program are expected to commence receipt in early Q2.

• Ongoing geological interpretation and wireframing to optimise Phase 2 deeper drilling.

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
Sampling techniques	• Nature and quality of sampling • measures taken to ensure sample representivity. • Aspects of the determination of mineralisation that are Material to the Public Report.	• Diamond drill core of HQ-3 size (61.1mm diameter) was collected from both the reported intervals as part of the Lasagne Zone evaluation drilling at Spring Hill. The core is oriented based on the driller’s mark from the down-hole orientation tool, and the bottom of core line marked along with the down-hole direction, recoveries measured, and logged in detail for lithology, mineralisation, and structure. The sample intervals are marked with sample numbers and photographed. Core is processed in an automated core cutting facility on site at Spring Hill. Cut sheets are provided to the core cutting operator listing the required sample intervals, and their corresponding numbers and instructions for CRMs, blanks, and duplicates, if any. • Diamond core will be sawn in half, and one half of the core was used for assaying. The remaining half is retained in the core trays. Samples are taken generally on 1 m intervals, since the sheeted vein systems at Spring Hill contain numerous millimetre- to decimetre- thickness veins on which sampling of individual veins is impractical. Shorter sample intervals are taken at defined contacts of lithological units where relevant. Following cutting, the half core intervals are placed in pre-numbered calico bags The half core is dried and crushed at the Intertek sample preparation facility in Darwin, using jaw crushers, with the entire sample crushed to nominal -2 mm. The crushed product is then split, and 500g placed into a jar to be freighted to Intertek Perth for Photon assay, which has a lower detection limit of 0.02grams per tonne Au.
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).	Drill Type and details used at Spring Hill (2025 and 2026) • Drilling at Spring Hill in 2025 and 2026 has been a combination of reverse circulation drilling (RC) and diamond core drilling, all of which has been HQ-3, using the services of two core drilling contractors and one RC contractor. • RC drilling was completed using a 5 ¾ inch drop centre hammer. • Some Diamond drill holes for resource purposes will be drilled from RC pre-collars, followed by HQ3 coring. Wherever possible oriented core was collected, using state of the art downhole devices. Single shot surveys were run at generally 30 m intervals, presently a down-hole north- seeking gyro is being used to monitor hole direction and adjust drillparameters accordingly.
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	• For RC drilling sample recovery and condition are visually assessed and recorded in the drill log. • For diamond drilling drilled metres and recovered metres are recorded by the drill crew but later checked by company personnel. Any discrepancies noted were followed up with the drillers. Zones of core loss are recorded in the geological log and are assumed to have no gold. In general core recoveries for mineralised intervals are close to 100%. • Preferential sample loss effecting grade has not generally been obvious with either RC or DD drilling at Spring Hill.

	bias may have occurred due to preferential loss/gain of fine/coarse material.
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 RC chips and diamond core has been geologically logged. • Geological logging typically detailed lithology, veining, alteration, sulphides, and weathering. Alpha and beta angles of structures like bedding, contacts and veining are recorded when core can be orientated. • Logging was to an industry standard and of sufficient detail to support the resource model. • Drill core is photographed wet and dry for more detailed geotechnical logging. • Logging was quantitative and consist of diagnostics of the rocks and minerals and degree of the rocks weathering. • Recording of the observed characteristics was made into electronic devices. • 100% of the drill holes are logged. • Logging of all 1 m RC chip samples was carried out by the geologist onto handwritten logs and entered into the geological database, along with assay data, surveyed collar position and any down-hole survey information (usually for DD only).
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.	• RC samples are collected at 1 m intervals straight from the rig- mounted cyclone and riffle splitter. • Quality control procedures for RC drilling included the insertion of certified reference materials and blanks at a rate of 1 every 30 samples. Field duplicates were collected straight from the rig cyclone at a rate of 1 every 40 samples. • Sampling of diamond core is generally on 1m intervals and is selective based of observed indicators of mineralisation. Diamond core is sawn in half with one half sent off for analysis. • Quality control procedures for diamond drilling included the insertion of certified reference materials and blanks at a rate of 1 every 20 or 40 samples. • Given the coarse nature of gold at Spring Hill, “duplicate” quarter core assays would be statistically meaningless, and reliance has been placed on obtaining large sample sizes for representativity. Since 2025, all drill samples have been assayed for Au using 500g aliquots and Photon assays, which is current state of the art for coarse grained gold mineralisation of the type encountered at Spring Hill.
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. • Forgeophysical tools,	• All half- core samples are submitted to Intertek Darwin for sample preparation of 500g of -2mm aliquots for Photon assay of each interval with a lower limit of detection of 0.02g/tAu. The Photon method of gold assay is considered current state of the art for assay of gold at economic grades. • Quality control procedures are outlined in the sections above in

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.	• The coordinate reference system used for the project area is GDA94 / MGA zone 52. The GDA coordinate system has been used for interpretation of the resource model. • Drill hole locations were set out using a handheld GPS. After completion of the drillholes all collars were surveyed using a differential GPS (DGPS), generally to an accuracy of ±0.1 m in X, Y, and Z directions. All historic holes that have been locatable have also been picked up using DGPS instruments. • Accurate drill rig alignment was achieved using both visual compass orientations and a gyro alignment system. During and after completion of the drillhole, all holes were down-hole surveyed using a north-seeking gyro tool, or in earlier a magnetic single shot camera at 12 m or 30 m intervals. • A Spring Hill surface DTM was provided by Spring Hill for validation with RLs of the collar pick-ups and agree closely to the DTM. Where there are minor discrepancies, this is the result of more recent earth works. A recent Lidar survey is being processed and will be used to update the DTM.
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	• Drilling data spacing: • Infill drill data spacing was appropriate for the resource classification. The majority of drilling over the resource area is a nominal 25 m x 25 m pattern, with closer spaced infill drilling in specific areas. • This spacing is considered adequate to determine the geological and grade continuity for reporting of Mineral Resources.

Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• Gold was first worked at Spring Hill in 1880, during the first phase of serious gold mining activity that followed on from the discovery of coarse gold near Yam Creek in 1870 during the construction of the Overland Telegraph Line. At Spring Hill, numerous alluvial, eluvial and hard rock workings were in operation, mainly by Chinese miners. The extensive surface workings suggest that significant amounts of gold were extracted. About 20,000 oz of gold production was recorded between 1880 and 1905, and the area was worked intermittently until 1966. The major hard rock workings were on the Main (or Western) Lode where oxidised ore was mined in a shaft to a depth of up to 109 m, but there was also widespread eluvial and alluvial work on the steep slopes and narrow, high-energy gullies that drain the range. • From 1933 to 1938, the Spring Hill Gold Mining Company drove an adit from the east side of Spring Hill with the portal 120 m below the surface exposure of the Main Lode. In 1949, Northern Territory Prospecting and Development Co. extended the adit to 427 m, reached the Main Lode, and carried out a little development work. Another company, Spring Hill Gold NL later carried out some stoping on the East Lode, but production was limited by a lack of water to process ore through the battery near the adit portal. Total gold produced from the Main Adit East Lode stopes was 20.2 kg gold at an average ore grade of 18.6 g/t Au. • From 1985 to September 1988 Territory Resources NL held the key leases over the major mined areas. The Main Adit was reopened, mapped and sampled where possible. • Ross Mining NL acquired the project from Territory Resources in 1988,and soon after formed an exploration

		joint venture with Billiton Australia (at the time, the metals division of The Shell Company of Australia Limited), who carried out a major programme of work as operators from November 1988 until it withdrew from the Spring Hill Joint Venture in March 1992. • In 1989-91, Billiton installed a 25m line spaced grid over the tenements that was used for geological mapping, soil sampling and a ground magnetic survey, followed by costeans, reverse circulation and diamond drilling, as well as some metallurgical testwork, petrology, a TEM survey, structural mapping and mineralisation modelling. This resulted in encouragement, with a 300 m extension to the Hong Kong Vein System recognised on the west side of the Property by 1990. • In the north part of the deposit, as far as 11900N, soil results produced discrete geochemical anomalies over veining of the Lasagne vein system, between 10400N and 11900N. The Lasagne system is largely within Gerowie Tuff, with a variety of vein styles including saddle reefs, bedding parallel, and tension gash styles, dominantly on the west limb of the main anticline. The tension gash style is parallel to the orientation of the Hong Kong System. While veining is strongly developed, the grades returned at Lasagne were low, with the best result being 0.47 g/t Au. It was noted that the veins are quartz- rich and have a lower sulphide content than those that carry gold further south in the vein systems in Mount Bonnie Formation. • The 1989-91 drilling program proceeded in five phases: o In June 1989, 25 RC holes were drilled for 2,428 m at targets from earlier grid soil BLEG sampling. In October 1989, an additional 26 RC holes for 2,600 m were drilled, focusing on optioned leases to assist with exercise decisions, as well as infill at “Strawberry Pastry” (later renamed Macau?), Hong Kong, and a southern extension of Hong Kong at the time called “Toothpaste”. o Diamond drilling in 1990 of 608 m in holes SHDH001 to SHDH007 at Hong Kong and the main anticline. The best intersection was in SHDH001 at Hong Kong, where 30 m at 1.82 g/t Au was intersected between 67 m and 96 m. o Drilling of RC holes SHRC052 to SHRC067 hit individual intersections of significance at Main Lode, Middle Lode and Hong Kong, while four holes drilled at Lasagne were unsuccessful. o In 1991, drilling of RC holes SHRC068 to SHRC078 (863 m), then later a second program drilled SHRC079 to SHRC087(688m). o Diamond drilling in 1991 consisted of four holes, SHDH008 to SHDH010 (775 m), which were extensions of SHRC077, SHRC072, and SHRC078 respectively; and the 50 m vertical HQ hole, RM001, to obtain samples for metallurgical test work from the main lens of the Hong Kong sheeted vein system. • Billiton completed a column leachingtest on the

		presumably oxidised crushed core from hole RM001, which produced a recovery of 73% of Au over 83 days, with 50% recovery in the first 6 days. • Billiton also reinterpreted the resource distribution and re- estimated the resource based upon their exploration. • In May 1991, Billiton were able to purchase 100% of the Union Reefs Project (MLN1109) and appear to have withdrawn from their other joint ventures with Pegasus at Mount Todd and with Ross Mining at Spring Hill after this success at Union Reefs. • In March 1992, Ross Mining NL reached agreement to purchase Shell’s 50% in Spring Hill and finalised the agreement on 3rd August 1992. Ross Mining then proceeded to explore the Spring Hill Project in their own right. In the remainder of 1992, Ross Mining compiled the Billiton data and produced an updated Mineral Resource estimate on the Hong Kong Sheeted Vein Resource (Indicated and Inferred resources of 3.4 Mt at 1.5 g/t Au for 158 k Oz Au, not constrained by pit optimisation shells). • Ross Mining conducted an active exploration program on the Spring Hill titles during 1993 and 1994. The first phase of this was detailed field checking, including mapping and sampling of selected portions of the project area based on the previous results to develop a detailed proposal for field work, accompanied by drilling of 13 RC holes, SHRC089 to SHRC101 for 1,287m in October 1993 to follow up early findings (Melville, 1994). • This resulted in Ross elevating the exploration intensity at Spring Hill in 1994, (Sheldon, Scrimgeour and Edwards, 1994). This work identified extensions to the Hong Kong Vein System, and new mineralised zones at Steve’s Gully, Vein Heaven, and Zbonsky Trend, confirmed with RC drilling. Diamond drilling also extended the dimensions of the mineralised envelope along strike and to depth. The Hong Kong Zone was extended by 250 m to the north and 225 m to the south. • Following this program, the project moved to pre- feasibility studies in 1995, including water quality monitoring, environmental monitoring, metallurgical testwork, resource/ reserve estimations, scoping studies, and rehabilitation. • In the mid- 1990s Ross Mining was acquired by Placer Dome. All titles were surrendered on 12th March 2001. • During 2003, the subsequent owner of the Project, Tennant Creek Gold (NT) Pty Ltd, commissioned McDonald Speijers to undertake a first pass economic assessment of the mineralisation and to create a preliminary pit design for the Hong Kong, Main, Middle and East Zones. • In 2007 Western Desert Resources Limited (WDR) acquired the project from Tennant Creek Gold (NT) Pty Ltd. • In mid-2011 WDR Gold entered into a joint venture agreement with TM Gold Pty Ltd (a subsidiary of Thor Mining PLC) for a 25% share in the project. TM Gold subsequently purchased 100% of the project. Thor Mining completed DD drilling,metallurgical testwork,a high-

		resolution aeromagnetic survey and screen fire assay testwork. • Thor commenced a divestment process to private equity firm, PC Gold Pty Ltd in late 2015. • PC Gold has since conducted significant brown field exploration drilling and provided new significant intersections which have been used for updating the mineral resources to the presently quoted quantities in the PC2 IPO Prospectus.
Geology	• Deposit type, geological setting, and style of mineralisation.	• The Spring Hill Project is in the Central Domain of the Pine Creek Orogen (PCO), most recently described in detail by Ahmad and Munson (2013). The stratigraphy at Spring Hill falls within the South Alligator Group and Finniss River Group of the Cosmo Supergroup, in greenschist facies metamorphosed sediments, which are isoclinally folded along north- west trending axes in an embayment with lobes of the Cullen Batholith to the north- east and south- west. The main anticline at Spring Hill plunges at a moderate angle to the southeast. • Spring Hill also falls within the Pine Creek Shear Zone, a north-west / south- east trending strike- slip fault system that follows the same embayment between the Cullen Batholith lobes and appears to have been reactivated multiple times during and after granite emplacement. The Pine Creek Shear Zone is most likely a major control on gold mineralisation. The bulk of discovered mineralisation at Spring Hill has been deposited in structures in the Mount Bonnie Formation of the South Alligator Group. • Thes structural events controlling the distribution of gold mineralisation in and near the Pine Creek Shear Zone deposits most commonly follows a pattern of association with fold structures, in particular anticlines, in ferruginous quartz vein zones with a variety of structural controls. Spring Hill is one of the group of deposits in and around the Pine Creek Shear Zone that share similar characteristics.
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 drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does	• Tabulation of recent drillholes is contained in the supplementary data accompanying the IPO report. The data for holes relevant to this release are described withing the tables contained in this release. • For the sake of completeness, the following background information is provided in relation to the drill holes. • Easting, Northing and RL of the drill hole collars are in the coordinates of MGA94 Zone 52. • Dip is the inclination of the hole from the horizontal. For example, a vertically down drilled hole from the surface is - 90°. Azimuth is reported in magnetic degrees as the direction toward which the hole is drilled. • Down hole length of the hole is the distance from the surface to the end of the hole, as measured along the drill trace. Depth is the distance down the hole as measured along the drill trace. Intersection width is the downhole distance of an intersection as measured along the drill trace. • Drill hole length is the distance from the surface to the end

It is the opinion of the Competent Person that the exclusion of the historic drilling information does not detract from the understanding 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.	• Detailed information in relation to data aggregation methods is not relevant as no quantitative exploration results are being reported in this report. The information is not material in the context of this report, and its exclusion does not detract from the understanding of this report PH This needs to be updated. • Metal equivalent values are not used.
Relationship between mineralisation 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 down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole _length, true width not known’). _	• Most of the drill holes contained within the drilling database that are material to the June 2024 model (as reported in the IPO Prospectus) were drilled at right angle to the mineralisation at the Spring Hill deposit. The majority of holes were drilled at -60° angle to the local grid easting providing intersections normal to the mineralisation.
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 collar locations and appropriate sectional views.	• Maps and sections are included in the body of this report as deemed appropriate by the Competent Person.
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 results above 0.5 g/t Au lower cut-off or 1 g/t Au have been reported in previous public releases by PC Gold, particularly the recent IPO Prospectus of PC2.
Other substantive exploration data	• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological	• No other exploration data is considered meaningful or material in the context of this report and its exclusion does not detract from the understanding of this report.
