SIGNIFICANT RESOURCE UPGRADE AT WAGGA TANK
KEY POINTS:
Drilling success has delivered an updated pit-constrained Indicated/Inferred Mineral Resource Estimate at Peel’s 100%-owned Wagga Tank deposit:
-
Wagga Tank pit constrained MRE of 3.56Mt at 0.59% Cu, 0.63g/t Au, 33g/t Ag, 0.64% Pb and 0.70% Zn (1.82% CuEq[1] ) .
-

-
Updated Wagga Tank-Southern Nights MRE increased to 9.99Mt at 0.35% Cu, 0.41 g/t Au, 52 g/t Ag, 1.19% Pb and 2.78% Zn .
-
Updated global resource base increased to 22.91Mt at 1.03% Cu, 0.37g/t Au, 35g/t Ag, 0.72% Pb and 1.45% Zn
-
Global MRE contains approximately 235kt Cu, 271koz Au, 25.4Moz Ag, 166kt Pb, and 331kt Zn.
PEEL MINING TECHNICAL DIRECTOR ROB TYSON COMMENTED:
“Delineating a pit-constrained resource at Wagga Tank is a great outcome for the Company with approximately 21,100 tonnes copper, 72,500 ounces gold and 3.77 million ounces silver as well as significant lead and zinc defined within open pittable depths.
Importantly, the open pit resource has potential to transform Peel’s future mine development plans, offering a lower capital development cost than the current Pre-Feasibility Study work which assumes both Mallee Bull and Wirlong are developed as underground mines supplying ore to a new milling complex.
Work will continue at Wagga Tank including infill and metallurgical drilling and metallurgical testwork to optimise processing options.
Following the success at Wagga Tank, a review of gold and copper mineralisation associated with the Wagga Tank / Southern Nights area has identified several new targets for gold and copper exploration drilling.
These areas along with the nearby Nombinnie gold prospect will be investigated for their potential to add further near surface mineralisation.”

WAGGA TANK MINERAL RESOURCE ESTIMATE
Peel Mining Ltd ( ASX Code: PEX ) ( “Peel” or “the Company” ) is pleased to report a new, pit constrained Indicated & Inferred Mineral Resource Estimates (MRE) for its 100% owned Wagga Tank deposit, centred around 130km south of Cobar in Western NSW.
The MRE for the Wagga Tank deposit, and its incorporation into the Company’s greater South Cobar Project MRE, is reported in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code (2012)). The updated Wagga Tank MRE comprises Open Pit and Underground components. The Open Pit component represents estimates from a new block model reported at $A40/t and $60/t NSR cut offs within an optimal pit shell. The Underground component represents the January 2023 mineable shape (SSO) constrained Southern Nights-Wagga Tank MRE at A$80/t NSR cut-off depleted by the new Wagga Tank pit shell with no other changes to the resource model or optimal stopes.
Table 1 shows the Wagga Tank Open Pit Mineral Resource Estimate. Table 2 shows the updated combined Wagga Tank-Southern Nights Mineral Resource Estimate. Table 3 shows the updated South Cobar Project Global Mineral Resource Estimate. Table 4 is a comparison between the January 2023 Wagga Tanks-Southern Nights MRE and the updated April 2025 Wagga Tanks-Southern Nights MRE.

Note: South Cobar Project underground MREs are reported above A$80/tonne NSR cut-off and utilise mineable shapes, which include minimum mining widths and internal dilution to bound the MREs. May Day Open Pit utilised $40 and $50/t NSR cut-offs for oxide and sulphide resources respectively within an optimal pit. Wagga Tank Open Pit-constrained MRE utilised $40 and $60/t NSR cut-offs for Oxide and Transition/Fresh respectively within an optimal pit. Figures are rounded to reflect the precision of estimates and include rounding errors.
1 The CuEq calculation for Wagga Tank is based on copper, gold, silver, lead and zinc prices of A$14,458/t, A$3,647/oz, A$43.90/oz, A$3,283/t and A$4,267/t respectively. Metallurgical metal recoveries have been set for the Oxide, Transition and Fresh zones respectively as: 85/65/45% for Cu, 85/73/61% for Au, 85/81/77% for Ag, 0/39/78% for Pb, 0/45/90% for Zn. These parameters give the following formulae: Oxide: CuEq (%) = Cu (%) +(0.811 x Au (g/t) + 0.0098 x Ag (g/t); Transition: CuEq (%) = Cu (%) + 0.911 x Au (g/t) + 0.0122 x Ag (g/t) + 0.136 x Pb (%) +0.204 x Zn (%); Fresh: CuEq (%) = Cu (%) + 1.099 x Au (g/t) + 0.0167 x Ag (g/t) + 0.394 x Pb (%) + 0.59 x Zn (%). It is the Company’s opinion that all metals included in the copper equivalent grades have reasonable potential to be recovered and sold.

WAGGA TANK MINERAL RESOURCE ESTIMATE – OTHER MATERIAL INFORMATION SUMMARY
A summary of other material information pursuant to ASX Listing Rules 5.8.1 is provided below for the updated Wagga Tank Open Pit Mineral Resource Estimate. The Assessment and Reporting Criteria in accordance with the 2012 JORC Code and Guidelines are presented in JORC Table 1, Sections 1 to 3 to this announcement.
GEOLOGY, GEOLOGICAL INTERPRETATION & MINERALISATION
The Southern Nights-Wagga Tank deposits are located in EL6695. Wagga Tank was discovered in 1968 by a local pastoralist while grading a fenceline and the prospect was subject to various phases of exploration until 1989 when significant work ceased. In 2016, Peel acquired the prospect with initial drilling confirming a significant mineralised system. The discovery in 2017 of the “blind” high-grade Southern Nights deposit, led to a switch of focus to the Southern end of the mineral system.
Southern Nights-Wagga Tank occur within the Mt Kennan Volcanics and comprises a package of largely volcanic derived subaqueous mass-flow deposits and local coherent rhyolites that are locally informally termed Vivigani Formation. These volcanic rocks are contained within deep water, rhythmically bedded turbidite facies shales, siltstones and sandstones that are referred to as underlying Eastern Formation and overlying Wagga Tank Formation. Metamorphic grade is lower greenschist facies and the area is of low strain, evidenced by a weak penetrative cleavage developed in turbidite facies shales.
Late early Devonian sandstones and conglomerates (Mulga Downs Group) outcrop prominently to the west of the deposit and are also believed to be locally juxtaposed against Wagga Tank Formation shales/siltstones in downfaulted blocks within the main project area. Together these units are unconformably overlain by transported sediments deposited in fluvial/lacustrine environments during the Tertiary period (McQueen, 2008) and aeolian and fluvial/sheetwash sands, gravels, clays and soils deposited throughout the Quaternary to the present day. The thickness of the Tertiary/Quaternary cover varies dramatically over the deposit from >100m at Southern Nights to areas of outcrop at Wagga Tank. A laterite profile is well developed but is commonly partly truncated.
Massive sulphide mineralisation in the Southern Nights-Wagga Tank area have been defined discontinuously over a strike length of approximately 2km at four principal locations: Wagga Tank, Link Zone, Southern Nights Central and Southern Nights South. Massive sulphide mineralisation occurs at the stratigraphic contact between the Vivigani Formation and overlying Wagga Tank Formation. This contact dips steeply WNW at Southern Nights rotating to steep NW/SE at Wagga Tank where minor overturning occurs. The contact marks a change in depositional environment that is coeval with the cessation of volcanic activity and the subsequent on-set of relative quiescence that allowed for the largely undisturbed accumulation of laminated to massive sulphides on the palaeo-seafloor. The massive sulphides are now preserved at the base of the deep-water turbidite facies shales and siltstones that are informally referred to as the Wagga Tank Formation and overlie discordant, intensely altered stockwork vein zones that are developed in the footwall permeable volcaniclastics of the Vivigani Formation.
At Wagga Tank, the contact massive sulphides have been subject to oxide and supergene weathering processes, causing enrichment of Au and depletion of Cu-Ag-Pb-Zn in the now-gossanous massive sulphides. Au is well preserved in the gossanous facies and forms the most near-surface expression of economic mineralisation at Wagga Tank.

Page 7
==> picture [596 x 75] intentionally omitted <==
Deeper in the weathering profile, the leached Cu-Ag has precipitated into either oxide-supergene mineralisation (i.e. malachite-azurite-cuprite) above the base of oxidation, or into sulphide-supergene mineralisation (i.e. chalcocite-covellite) below the base of oxidation.
The highest concentrations of supergene mineralisation are seen within or immediately adjacent to where the massive sulphide horizon crosses the base of oxidation. Additionally, supergene mineralisation is also seen spread laterally to the SE along this base of oxidation, stretching up to 100m from the massive sulphides.
As a result, mineralisation modelling in this MRE has been divided into Oxide, Transition and Fresh categories.
Facies analysis of the Southern Nights-Wagga Tank deposits has resulted in the identification of the Link Zone volcanic centre and multiple syn-volcanic faults that are spatially associated with stratiform massive and stockwork vein zone mineralisation. The textures and geochemistry of mineralisation and alteration at Southern Nights-Wagga Tank are strongly suggestive of a VAMS origin for mineralisation that formed during the basin rifting phase, however Pb isotope data provides a counterargument to this hypothesis and suggest an age that is consistent with the basin inversion phase. Further work is needed to resolve this issue.

DRILLING TECHNIQUES
Since mineralisation was discovered at Wagga Tank in 1968, it has been owned and operated by several previous companies, including Newmont, Amoco Minerals, Homestake Australia, Cyprus Gold and Peel Mining. The table below (Wagga Tank MRE area only) sets out the companies that operated on the Project, the type, number, and metres drilled (Table 5).

Appendix A – “Significant Intercept Data – Wagga Tank” sets out in Table 9 the details of Significant Assays for Peel Mining and for Historic Drillholes used in the MRE.
Drilling completed by Peel, which comprises approximately 79% of the total drilling database, has been a combination of diamond (DDH) and reverse circulation (RC) or both (RCD). Reverse circulation drilling utilised a 5 1/2-inch diameter face sampling hammer. PQ, HQ and NQ coring was used for diamond drilling. Historic drilling, which comprises approximately 21% of the total drilling database, utilised a combination of DDH, RC or RCD. Historic DDH generally comprised NQ or HQ coring.

Drill spacing for Wagga Tank has been predominantly drilled at 40m x 40m spacing (although locally some drillholes are on a 20m x 20m spacing) on a 310/130 aligned grid.
Core drilled by Peel has been orientated predominantly using a REFLEX ACT™ system where data is stored on the controller and cannot be manipulated. Core samples were matched with orientation data using a spirit level jig. Diamond core was reconstructed into continuous runs on an angle iron cradle for orientation. Orientation quality was noted between orientation marks based on a tolerance. Any systematic failures were immediately raised with the drilling contractor.
A Garmin hand-held GPS is used to define the location of Peel’s drill holes with collars routinely picked up after drilling by DGPS. Down-hole surveys are conducted by the drill contractors using either a Reflex gyroscopic tool with readings every 10m after drill hole completion or a Reflex electronic multi-shot camera with readings for dip and magnetic azimuth taken every 30m down-hole. QA/QC in the field involves calibration using a test stand. The instrument is positioned with a stainless-steel drill rod so as not to affect the magnetic azimuth. Grid system used is MGA 94 (Zone 55). All down-hole magnetic surveys were converted to MGA94 grid. DGPS pick-up delivers adequate topographic control.
SAMPLING AND SUB-SAMPLING TECHNIQUES
The sample information used in resource estimation was derived from reverse circulation and diamond drilling. Aircore and RAB drillholes were used to assist in the geological interpretation but were excluded from the estimation. The Wagga Tank area has been subject to various drill programs, with Peel’s work accounting for the bulk of all drilling.
Peel’s diamond and reverse circulation drilling were used to obtain samples for geological logging and assaying. Diamond core was cut and sampled at 1m intervals on average or intervals determined by geological contacts. RC drill holes were sampled at 1m intervals and split using a cone splitter attached to the cyclone to generate a split of 2-4kg to ensure sample representivity.
Drill core was cut with a core saw with half core taken for analysis. The RC drilling rigs were equipped with an in-built cyclone and splitting system, which provided one bulk sample of approximately 20kg and a subsample of 2-4kg per metre drilled. All samples were split using the system described above to maximise and maintain consistent representivity. The majority of samples were dry. Bulk samples were placed in green plastic bags, with the sub-samples collected placed in calico sample bags. Field duplicates were collected by re-splitting the bulk samples from large plastic bags. These duplicates were designed for lab checks. Laboratory duplicate samples were riffle split using ALS method SPL-21d. These samples were selected by the geologist within moderate and high-grade zones. A sample size of 2-4kg was collected and considered appropriate and representative for the grain size and style of mineralisation.
SAMPLE ANALYSIS
Multi-element readings of samples in the field was by portable XRF instruments: Olympus Delta Innov-X or Olympus Vanta Analysers. Reading time for Innov-X was 20 seconds per reading with a total 3 readings per sample. Reading time for Vanta was 10 & 20 seconds per reading with 2 readings per sample. At least one daily calibration check was performed using standards and blanks to ensure the analyser was operating within factory specifications. The XRF readings are only used as indicative and assist with the geological

interpretation and selection of sample intervals for laboratory analysis. No XRF measurements are used in resource estimation.
Assay quality control procedures adopted by Peel include reference standards. Although there is some variability for individual samples, average assay results reasonably match expected values for all attributes. ALS Laboratory Services located in Orange NSW, was generally used for sample preparation, Au, and multielement analysis work. Analysis for sulphur by Leco or multi-element 4 Acid digest was undertaken at ALS Brisbane.
The laboratory preparation and analysis methods below are for all samples submitted to ALS by Peel and are considered appropriate determination of the economic minerals and styles of mineralisation defined at Wagga Tank. Sample preparation was generally undertaken at ALS Orange using the following process:
-
Crush entire sample nominal >70% passing 6mm.
-
If sample >3kg, Riffle split sample to maximum of 3.2Kg and pulverise split in LM5 to 85% passing 75µm. Retain and bag unpulverised reject (bulk master). If sample <3.2kg, entire sample is pulverised.
Routine assays were completed using either:

ME-ICP41 analysis, Aqua-regia digest (GEO-AR01) ICP-AES finish performed at ALS Orange. Over-limit assays were then undertaken using ME-OG46 analysis if triggered from above (i.e., Cu, Pb, Zn >1%, Ag >100ppm) Aqua-regia digest (ASY-AR01) with ICPAES finish performed in Brisbane from pulp split. Over-limit sulphur was undertaken with S-IR08 Leco Fusion (>10% S).
-
ME-ICP61 or ME-MS61, 4 acid digest (GEO-4 ACID) ICP-AES finish /ICP-MS finish performed at ALS Brisbane from pulp split. Over-limit assays were then undertaken using ME-OG62 analysis if triggered from above (i.e., Cu, Pb, Zn >1%, Ag >100ppm) 4 acid digest (ASY-4ACID) with ICP-AES finish/ ICP-MS finish performed in Brisbane from pulp split. Over-limit sulphur was undertaken with S-IR08 Leco Fusion (>10% S).
Samples with over-range assays for Ag which exceeded the upper limits of ALS analysis ME-OG62 were sent to SGS Laboratory in Perth for gravimetric analysis using the method GC_FAG38V (Control grade 30g Fire Assay with Gravimetric Finish).
QAQC samples were inserted in the form of Certified Reference Materials, blanks (sand and coarse) and duplicates. CRM and blanks were inserted at the rate of at least 1 blank and standard every 20 samples. Duplicates for percussion drilling were collected directly from the drill rig at a rate of 1 every 20 samples. The duplicate rate for drill core varies as they are selected by geologists to cover low, medium, and high-grade zones. These duplicates were split at the laboratory after the crushing stage. At a minimum there is one duplicate every 20 samples. Through high grade zones, additional blank lab wash is requested with analysis randomly selected on these washes by Peel to monitor cross contamination.
The standards generally performed well with results falling within prescribed two standard deviation limits and only random occurrences outside of these limits. The performance of the pulp and coarse blanks have been within acceptable limits with no significant evidence of cross contamination identified. ALS laboratories undertake internal QC checks to monitor performance. The results of these are available to view on ALS Webtrieve™ (an ALS online data platform).

METALLURGY
Metallurgical testwork completed by Peel, primarily undertaken at ALS Burnie, has guided the metallurgical recoveries assigned to the Wagga Tank Pit Constrained MRE. Metallurgical samples at Wagga Tank have been taken from quarter core PQ and HQ diameter, and composited material from RC drilling. A total of 2 diamond holes plus 5 RC holes have been used for metallurgical testwork.
Work to date has comprised series of sequential and locked cycle flotation tests, as well as gravity and cyanide leach tests for gold/precious metals, and acid leach testwork for oxide copper minerals. Metallurgical testwork remains ongoing.
Table 6 – Cumulative metallurgical recovery assumptions used in the Wagga Tank MRE
| Mineralisation | Metal | Cumulative Recovery (%) |
|---|---|---|
| Oxide | Copper | 85 |
| Gold | 85 | |
| Silver | 85 | |
| Transition | Copper | 65 |
| Gold | 73 | |
| Silver | 81 | |
| Lead | 39 | |
| Zinc | 45 | |
| Fresh | Copper | 45 |
| Gold | 61 | |

| Zinc | 90 |
CUT-OFF VALUES
The Wagga Tank open pit MRE utilised A$40/t and A$60/t NSR cut-offs for Oxide and Transition/Fresh mineralisation respectively, reflecting various processing concepts relevant to the expected styles of mineralisation: oxide mineralisation is anticipated to be recovered via conventional cyanide leach (Au-Ag) and acid leach (Cu); transitional mineralisation is anticipated to be recovered by a combination of acid leach (Cu), gravity (Au), staged floatation (Cu-Pb-Zn) and cyanide leach (Au-Ag); fresh mineralisation is anticipated to be recovered by gravity (Au), staged floatation (Cu-Pb-Zn) and cyanide leach (Au-Ag).
Underground resources are reported within SSO shapes developed at A$80/t NSR cut off. The cut-off value selected for underground Mineral Resources reflects Peel’s interpretation of potential processing costs for fresh mineralisation, i.e., gravity (Au), staged floatation (Cu-Pb-Zn) and cyanide leach (Au-Ag); and conventional underground mining (long hole open stoping or similar).
The cut-offs were derived from the cost and revenue used for pit optimisation (Tables 6, 7 & 8), with appropriate rounding, to reflect interpreted potential operational practicalities.

NET SMELTER RETURN
For the reporting of the cut off values for the Wagga Tank Open Pit MRE, a Net Smelter Return (NSR) value has been used to reflect the polymetallic nature of mineralisation. NSR in A$/t, represents the potential economic value of mineralisation net of all costs after it leaves site, and was applied to each block within the block model after estimation.
Metal price assumptions were based on late 2024 Australian dollar metal consensus pricing (see Table 7).
Table 7 – Metal price assumptions used in the Wagga Tank Open Pit MRE
| Commodity | Assumption |
|---|---|
| A$ Copper Price | $14,458 / tonne |
| A$ Gold Price | $3,647 / ounce |
| A$ Silver Price | $43.90 / ounce |
| A$ Zinc Price | $4,267 / tonne |
| A$ Lead Price | $3,283 / tonne |
The NSR formula includes assumptions regarding metal prices, exchange rates, metallurgical recoveries, metal marketing terms (including payabilities and deductions/penalties), freight, smelting and refining charges, and royalties.
The NSR formula is: NSR = (metal grades x metallurgical recoveries x payabilities x A$ metal prices) less (concentrate freight and treatment charges, penalties, and royalties)
ASSESSMENT FOR REASONABLE PROSPECTS FOR EVENTUAL ECONOMIC EXTRACTION
To provide estimates with reasonable prospects of eventual economic extraction consistent with JORC 2012 guidelines, the Wagga Tank Open Pit Mineral Resources was constrained within an optimal pit generated on the basis of the mining, trucking and processing costs and wall angles specified in Table 8, commodity prices in Table 7, and cut off values applied to resource block model. The MRE also assumes a 90% mining recovery.
Table 8 – Pit optimisation parameters
| Oxide | Transition | Fresh | ||
|---|---|---|---|---|
| Mining cost ($A) | Cost per bcm | $12 | $14 | $16 |
| Trucking + Processing + G&A cost ($A) | Cost per tonne | $40 | $60 | $60 |
| Wall Angles | Degrees | 45o | 50o | 55o |
Mining and processing costs were benchmarked against other Australian operations, and Peel’s assessment of recent industry costs. Open pit resources represent model estimates for oxide and transition/fresh material within the pit shell at NSR cut-off grades of A$40 and A$60/t respectively. The commodity prices are consensus derived pricing from late 2024.
The optimal pit extends over around 460 metres of strike with a maximum with of around 430 metres and reaches with a maximum depth of around 240 metres as shown in Figures 1 and 2.

The Wagga Tank underground MRE excludes mineralisation within the optimal pit shell but no changes to the previous underground mining assumptions have occurred in relation to the underground MRE.
The modifying factors (including metallurgical recoveries, mining recovery, metal pricing, NSR, and mining and processing costs) incorporated in the Wagga Tank Open Pit MRE underpin Peel’s opinion that all of the economic metals included have reasonable prospects for eventual economic extraction.
OTHER MODIFYING FACTORS
The Cobar region has a long history of base and precious metals mining and there are not expected to be any environmental or land access issues that would prevent conventional open-pit mining or the construction of waste dumps.
WAGGA TANK OPEN PIT ESTIMATION METHODOLOGY & RESOURCE MODELLING
The block model informing open pit mineral resources is based on two metre down-hole composited assay grades from RC and diamond drilling available for the project in February 2025 as extracted from Peel’s master Geobank Database.
Subset to the general Wagga Tank area, the compiled database informing the estimates, which excludes six historic holes with limited assay coverage totals 71 RC and diamond holes for 22,626 metres of drilling including 26 RC holes for 4,169 metres drilled during 2024.
Mineral resources are primarily informed by data from Peel RC and diamond drilling which respectively provide around 63% and 23% of estimation dataset mineralised domain composites within the pit shell constraining mineral resources. Combined Homestake and Newmont RC and diamond drilling contribute around 1% and 13% respectively.
Modelling domains comprise oxidation surface interpretations provided by Peel, mineralised domains interpreted by Matrix with reference to interpretation by Peel geologists and a surface representing the base of surficial soils and clays interpreted by Matrix, which ranges from around 0.50 metres thick in the mineralised zone to locally around 7 metres in peripheral areas.
The oxidation domains comprise an oxide zone, which, within the resource pit shell averages around 80 metres thick, underlain by a transition zone averaging around 60 metres thick with fresh rock occurring at an average depth of around 150 metres.
The mineralised domains comprise a NE (035) trending, subvertical envelope capturing continuous zones of composited copper equivalent grades of greater than approximately 0.1%, which is subdivided into a generally higher grade, more continuously mineralised contact zone, and an eastern domain of more variable, commonly lower grade mineralisation, which is commonly not developed within the oxide zone. The contact zone is consistent with, and somewhat wider than mineralised domain utilised for underground resource modelling.
The combined mineralised envelope is interpreted over around 470 metres of strike and extends from the base of surficial material to around 560 metres depth. The contact zone averages around 23 metres thick, with horizontal widths of the eastern zone averaging around 30 metres.

==> picture [596 x 75] intentionally omitted <==
The open pit block model comprises 10 metres by 20 metres by 5 metres (X,Y,Z) parent blocks aligned with the 035 trending mineralised domains. Parent block dimensions were selected on the basis of sample spacing in the more closely drilled portions of the deposit and were sub-blocked to minimum dimensions of 2.5 metres by 10 metres by 1.25 metres for precise representation of domain boundaries. Copper, gold, silver, lead and zinc grades estimated by Ordinary Kriging of two metre down hole composited assay grades within the mineralised domain with upper cuts selected by mineralisation and oxidation zone and generally approximating the 99.5th percentile of each dataset. For oxide portions of the eastern zone composites show generally low zinc grades and zinc grades for this zone, which does not contribute to Mineral Resources were estimated without upper cuts.
The Ordinary Kriging employed eight, progressively relaxed search passes with ellipsoids aligned with mineralised domain orientations The (cross strike, strike, down dip) radii and minimum data requirements of these search ellipsoids were respectively as follows 10 by 20 by 10 metres (8 data), 15 by 30 by 15 metres (8 data), 15 by 40 by 20 metres (8 data), 15 by 60 by 30 metres ((8 data), 15 by 60 by 30 metres (8 data), 15 by 60 by 30 (4 data) metres, 45 by 135 by 135 (4 data), metres, 45 by 135 by 135 metres (2 data). Blocks informed by search passes 1 to 3 provide the majority of combined Indicated Mineral Resources (92%) with search pass 3 informing 3%. Blocks informed by search passes 1 to 5 inform 97.3% of Inferred Mineral Resources with search pass 6 and 7 blocks providing 2.3 and 0.4% respectively. Search pass 8 does not inform Mineral Resources.
Oxide zone model blocks were assigned a density of 2.50 t/bcm on the basis of immersion density measurements of diamond core for this zone. Densities were assigned to transition and fresh model blocks by Ordinary Kriging of drill hole composites with density values assigned to composites from immersion measurements or density versus sulphur functions for composites without density measurements and with sulphur assays. For a comparatively small portion of the Wagga Tank mineralised envelope where diamond core shows numerous cavities and low-recoveries, assigned densities were factored by 40% reflecting average core-recoveries for this zone. The un-mineralised surficial zone which does not inform mineral resources was assigned a density of 1.8 t/bcm on the basis of the competent person’s experience of similar material.
The optimal pit used to constrain the Open Pit Mineral Resources was generated on the basis of block NSR values and conceptual cost and revenue, and mining parameters described in Table. It extends over around 460 metres of strike with a maximum with of around 430 metres and reaches with a maximum depth of around 240 metres.
Open pit resources represent model estimates for oxide and transition/fresh material within the pit shell at NSR cut-off grades of A$40 and A$60/t respectively. This approach is considered appropriate for providing estimates with reasonable prospects of eventual economic extraction consistent with JORC 2012 guidelines.
The open pit resources include copper equivalent grades base on copper, gold, silver, lead and zinc prices of A$14,458/t, A$3,647/oz, A$43.90/oz, A$3,283/t and A$4,267/t respectively. Metallurgical metal recovery assumptions for the Oxide, Transition and Fresh zones are 85/65/45% for Cu, 85/73/61% for Au, 85/81/77% for Ag, 0/39/78% for Pb, 0/45/90% for Zn, and are based on metallurgical testwork completed at ALS Burnie. In the Company’s opinion that all elements included in the copper equivalent grades have reasonable potential to be recovered and sold. Copper contributes the most metal to the equivalent calculation. These parameters give the following formulae:
www.peelmining.com.au
Page 14
==> picture [596 x 75] intentionally omitted <==
Oxide: CuEq (%) = Cu (%) + 0.811 x Au (g/t) + 0.0098 x Ag (g/t) Transition: CuEq (%) = Cu (%) + 0.911 x Au (g/t) + 0.0122 x Ag (g/t) + 0.136 x Pb (%) + 0.204 x Zn (%) Fresh: CuEq (%) = Cu (%) + 1.099 x Au (g/t) + 0.0167 x Ag (g/t) + 0.394 x Pb (%) + 0.59 x Zn (%)
The Mineral resources make no allowance for recovery of lead and zinc for the oxide zone and lead and zinc estimates for this zone do not inform Mineral Resources.
Micromine software was used for data compilation, calculating and coding of composite values. GS3M was used for Kriging, and the estimates were then imported into a Micromine block model for pit optimisations and reporting.
OPEN PIT RESOURCE CLASSIFICATION
Classifications assigned to open pit resources reflect confidence in the reliability of the informing data, interpreted mineralisation continuity for each mineralised domain and drill hole spacing.
Indicated mineral resources are extrapolated to a maximum of around 20 metres from drilling with around 95% within 15 metres of drilling. Inferred mineral resources are extrapolated to a maximum of around 50 metres from drilling with around 93% within 30 metres of drilling.
Model blocks are classified as Indicated and Inferred by estimation search pass and cross-sectional polygons outlining areas of relative consistently spaced drilling. The classification approach assigns estimate for transition and fresh contact zone blocks tested by drilling spaced at around 30 by 30 metres and closer to the Indicated category with estimates for more broadly sampled zones, and all of the eastern mineralised domain and oxide zone, for which mineralisation is less well-structured classified as Inferred.
Indicated Mineral Resources are based on drilling spaced at around 30 by 30 metres and locally closer extrapolated to a maximum of around 20 metres from drilling with around 95% within 15 metres of drilling. Inferred Mineral Resources comprise estimates for the Main mineralised domain tested by drilling spaced at generally between around 30 by 30 metres and 60 by 60 metres and all estimates for the east domain which are based on drill spacing ranging from around 30 by 30 metres to rarely 100 metre spacing. Inferred Mineral resources are extrapolated to a maximum of around 50 metres from drilling. Around 93% within 30 metres of drilling.
SOUTHERN NIGHTS-WAGGA TANK UNDERGROUND ESTIMATION METHODOLOGY & RESOURCE MODELLING
The combined Southern Nights-Wagga Tank resource models informing underground resources are unchanged from those used for reporting Mineral Resources in January 2023. They include block models constructed for Southern Nights and Wagga Tank respectively with the Wagga Tank model rotated 35[o] from north-south reflecting general mineralised trends in this area. The models are based on 88,037 metres of RC and diamond drilling as extracted from Peel’s master Geobank Database, predominantly completed by Peel from the project’s acquisition in 2016 to 2022, Additional drilling undertaken since that time does not intersect the underground resource volume.
The models are based on sampling information and an oxidation surface interpretation provided by Peel and mineralised domains interpreted by Matrix with oversight by Peel. The mineralised domains capture
www.peelmining.com.au
Page 15
==> picture [596 x 75] intentionally omitted <==
continuous drill hole intervals with NSR values of nominally greater than A$60/t with lower grade intercepts included for continuity. These domains comprise main contact zones at Southern Nights and Wagga Tank and one main and four subsidiary eastern zones at Southern Nights. The Southern Nights contact zone includes three internal zones capturing higher grade, massive sulphide mineralisation.
For each block model zinc, lead, copper, gold and silver grades were estimated by Ordinary Kriging of generally 1m down-hole composited assays from RC and diamond drilling within mineralised domains. Densities were estimated by Ordinary Kriging with density values assigned to composites from immersion measurements or sulphur and zinc versus density functions for intervals without density measurements. Zinc, lead and silver grades, which are strongly positively correlated with density, were estimated by Kriging accumulation variables and metal grades back calculated. Copper and gold grades were directly Kriged.
Composites were assigned density values from immersion density measurements where available. The remaining composites were assigned densities from sulphur versus density functions or less commonly zinc versus density functions.
Estimation of each attribute included upper cuts selected on a domain-by-domain basis which generally approximate the 99th percentile of each dataset. These upper cuts reduce the impact of a small number of outlier composite grades. The combined estimation dataset comprises 3,992 composites of which most (85%) are from diamond drilling, and comparatively few (6%) are from historic holes drilled by previous tenement holders.
Attribute values were Kriged into parent blocks of 1 metre by 10 metres by 10 metres and the parent cells were sub-blocked to minimum dimensions of 0.5 metre by 2.0 metres by 2.0m metres for precise representation of domain volumes. Parent block dimensions were selected on the basis of the commonly narrow mineralised domains, sample lengths and drill spacing. The northing and elevation dimensions approximate half the drill intercept spacing in closely drilled portions of the mineralisation.
UNDERGROUND RESOURCE CLASSIFICATION
Classifications assigned to underground resources reflect confidence in the reliability of the informing data, interpreted mineralisation continuity and drill hole spacing. Estimates with consistently 40 metres by 40 metres and closer spaced drilling were classified as Indicated, and estimates tested by up to approximately 80 metres by 80 metres spaced drilling, extrapolated to around 40m from drill hole intercepts were assigned to the Inferred category. For Mineral Resource reporting, the underground block model is constrained within optimal stope shapes generated at A$80/t NSR cut-off with small peripheral zones excluded and trimmed below the optimal pit shell constraining open pit resources.

APPENDIX B – JORC CODE (2012 Edition) – Table 1 Section 1: Sampling Techniques and Data
| 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 (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. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Peel Mining Diamond and reverse circulation (RC) drilling were used to obtain samples for geological logging and assaying. Diamond core was cut and sampled at 1m intervals on average or intervals determined by geological contacts. RC drill holes were sampled at 1m intervals and split using a cone splitter attached to the cyclone to generate a split of 2-4kg to ensure sample representivity. Multi-element readings were taken of the diamond core and RC drill chips using an Olympus Delta Innov- X portable XRF machine or an Olympus Vanta portable XRF machine. Portable XRF machines are routinely serviced, calibrated and checked against blanks/standards. Metallurgical samples at Wagga Tank have been taken from quarter core PQ and HQ diameter, and composited material from RC drilling. A total of 2 diamond holes plus 5 RC holes have been used for metallurgical testwork. Historic Explorers Historic drilling referenced in this announcement comprised percussion, RC and/or diamond. Information regarding historic drilling has been taken from original reports as per Table 13 “References to Historic Explorers’ Drill Results”. Drilling was completed between 1980 and 1989. Sample weight, quality, collection method and condition varied by company. It is assumed samples were dispatched using industry standard chain of custody documents to track samples. Sample methods and sampling intervals / composites varied by company. Standard industry sampling and lab techniques were used. Anomalous composite results were often followed up and some companies did someQAQC re-assaying. |

| 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). |
Peel Mining Drilling to date has been a combination of diamond and reverse circulation. Reverse circulation drilling utilised a 5 1/2-inch diameter hammer. PQ, HQ and NQ coring was used for diamond drilling. Core has been orientated predominantly using a REFLEX ACT™ system where data is stored on the |

| controller and cannot be manipulated. Core samples were matched with orientation data using a spirit level jig. Diamond core was reconstructed into continuous runs on an angle iron cradle for orientation. Orientation quality was noted between orientation marks based on a tolerance. Systematic failures were immediately raised with the drilling contractor. Historic Explorers Historical drilling varied from RC, percussion, RAB to diamond drilling. Bit sizes varied by company but generally included HQ and NQ diamond holes. Information regarding drilling data has been taken from original reports as per Table 13 “References to Historic Explorers’ Drill Results” included in this release. |
|||
| 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. |
Peel Mining Core recoveries were recorded by the drillers in the field at the time of drilling and checked by a geologist or technician. RC samples were not weighed on a regular basis, but no significant sample recovery issues have been encountered in drilling programs to date. Diamond core was reconstructed into continuous runs on an angle iron cradle for orientation marking and depths are checked against the depths recorded on core blocks. Rod counts were routinely undertaken by drillers. When poor sample recovery was encountered during drilling, the geologist and driller endeavoured to rectify the problem to ensure maximum sample recovery. Historic Explorers Logging contained information related to sampling and varied by company. Diamond core recovery was generally recorded however sample recovery for RC and percussion was rarely recorded in historic data. Standard industry practise notes cavities or intervals with unusual sample return. Given the historic it is not possible to provide any details in relation to sample recoveryandgrade. |
|
| 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. |
Peel Mining All drill core and drill chip samples were qualitatively geologically and quantitatively geotechnically, geochemically and structurally logged from surface to the bottom of each individual hole to a level of detail |

to support appropriate MRE, mining studies and metallurgical studies. All logging of diamond core, RC and RAB samples records lithology, alteration, mineralisation, structure (DDH only), weathering, colour and other features of the interval important for defining the location of the drillhole within the mineralised system. All drill core and chip trays were photographed as both wet and dry. Where core samples are orientated, drill core was logged for geotechnical and structural information by measuring alpha and beta angles accompanied by a description of the feature being logged. Bulk density by Archimedes principle (hydrostatic weighing) were taken at regular intervals (minimum 2 every core tray through mineralisation). Magnetic susceptibility was recorded at 1m intervals. Historic Explorers Chip samples and / or diamond core were geologically logged for the entire length of the drillhole. Logging was both qualitative and semi-quantitative in nature. Logging templates and logging codes varied by company. Data is sufficient to assist in MRE modelling. Geological logging data is available in the original reports as per Table 13 “References to Historic Explorers’ Drill Results” included in this release. |

| 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. |
Peel Mining Drill core was cut with a core saw with half core taken for analysis. The RC drilling rigs were equipped with an in-built cyclone and splitting system, which provided one bulk sample of approximately 20kg and a sub-sample of 2- 4kg per metre drilled. All samples were split using the system described above to maximise and maintain consistent representivity. The majority of samples were dry. Bulk samples were placed in green plastic bags, with the sub-samples collected placed in calico sample bags. Field duplicates were collected by re-splitting the bulk samples from large plastic bags. These duplicates were designed for lab checks. |

| Laboratory duplicate samples were riffle split using ALS method SPL-21d. These samples were selected by the geologist within moderate and high-grade zones. A sample size of 2-4kg was collected and considered appropriate and representative for the grain size and style of mineralisation. Historic Explorers Where diamond, generally half core was taken. For RC and percussion, most sampling was riffle split. It appears that sample preparation techniques were generally appropriate for the sample types. Samples were sorted, dried and weighed at the laboratory where they were then crushed and riffle split to obtain a sub-fraction for pulverisation. Field duplicates were frequently used and submitted with drill samples by the companies. The frequency of this varied by each of the previous explorers but generallyfollowed industrynorms. |
|||
| 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 (ie lack of bias) and precision have been established. |
Peel Mining No geophysical measurements including hand-held XRF measurements were used in the Mineral Resource estimates. Assay quality control procedures adopted by Peel include reference standards. Although there is some variability for individual samples, average assay results reasonably match expected values for all attributes. ALS Laboratory Services located in Orange NSW, was generally used for sample preparation, Au, and multi- element analysis work. Analysis for sulphur by Leco or multi-element 4 Acid digest was undertaken at ALS Brisbane. The laboratory preparation and analysis methods below are for all samples submitted to ALS by Peel and are considered appropriate determination of the economic minerals and styles of mineralisation defined at Wagga Tank. Sample preparation was generally undertaken at ALS Orange using the following process: Crush entire sample nominal >70% passing 6mm. If sample > 3kg, Riffle split sample to maximum of 3.2Kg and pulverise split in LM5 to 85% passing 75µm. Retain and bag unpulverised reject (bulk master). If sample < 3.2kg, entire sample is pulverised. Routine assays were completed using either: ME-ICP41 analysis, Aqua-regia digest (GEO-AR01) ICP- AES finishperformed at ALS Orange. Over-limit assays |

Over- limit sulphur was undertaken with S-IR08 Leco Fusion (>10% S). ME-ICP61 or ME-MS61, 4 acid digest (GEO-4 ACID) ICP- AES finish /ICP-MS finish performed at ALS Brisbane from pulp split. Over-limit assays were then undertaken using ME-OG62 analysis if triggered from above (i.e., Cu, Pb, Zn >1%, Ag >100ppm) 4 acid digest (ASY-4ACID) with ICP-AES finish/ ICP-MS finish performed in Brisbane from pulp split. Over-limit sulphur was undertaken with S-IR08 Leco Fusion (>10% S). Samples with over-range assays for Ag which exceeded the upper limits of ALS analysis ME-OG62 were sent to SGS Laboratory in Perth for gravimetric analysis using the method GC_FAG38V (Control grade 30g Fire Assay with Gravimetric Finish). Assaying of samples in the field was by portable XRF instruments: Olympus Delta Innov-X or Olympus Vanta Analysers. Reading time for Innov-X was 20 seconds per reading with a total 3 readings per sample. Reading time for Vanta was 10 & 20 seconds per reading with 2 readings per sample. At least one daily calibration check was performed using standards and blanks to ensure the analyser was operating within factory specifications. The XRF readings are only used as indicative and assist with the selection of sample intervals for laboratory analysis. QAQC samples were inserted in the form of Certified Reference Materials, blanks (sand and coarse) and duplicates. CRM and blanks were inserted at the rate of at least 1 blank and standard every 20 samples. Duplicates for percussion drilling were collected directly from the drill rig at a rate of 1 every 20 samples. The duplicate rate for drill core varies as they are selected by geologists to cover low, medium, and high-grade zones. These duplicates were split at the laboratory after the crushing stage. At a minimum there is one duplicate every 20 samples. Through high grade zones, additional blank lab wash is requested with analysis randomly selected on these washes by Peel to monitor cross contamination. |

| The standards generally performed well with results falling within prescribed two standard deviation limits and only random occurrences outside of these limits. The performance of the pulp and coarse blanks have been within acceptable limits with no significant evidence of cross contamination identified. ALS laboratories undertake internal QC checks to monitor performance. The results of these are available to view on ALS Webtrieve™ (an ALS online data platform). Historic Explorers Historical analyses reported are not all defined, however where reported, appear appropriate and in line with industry norms for the period in which they occurred. Digestion methods are not specified in available data. Laboratory QAQC data is unknown however major laboratories were used so it is assumed industry norms were met. Field duplicates were collected and certified reference material data was submitted with drill samples by some companies. The frequency of this varied by each of the previous explorers but generally followed industrybestpractise. |

| 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. |
Peel Mining All significant intersections have been verified by senior staff. Prior to 2019, geological and field data was entered into Microsoft Excel spreadsheets with lookup tables and fixed formatting. Data was then imported into a customised SQL database with validation undertaken on import. From 2019, Geobank mobile has been used for the collection of data. Data is validated during entry into Geobank with further validation undertaken during synchronisation with the main database. Assay data were imported directly from original lab files into the previous SQL database and now into Geobank with no prior manipulation of results. The Peel SQL database and recent Geobank database have robust validation and constraints incorporated into them to ensure validated data is readily available for fit for purpose use. The database is managed by a database administrator employed by Peel Mining. Database extracts were supplied by Peel Mining to Matrix in the form of text files exported from a Geobank 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. |
Peel Mining A Garmin hand-held GPS is used to define the location of the drill holes with collars routinely picked up after drilling by DGPS. Down-hole surveys are conducted by the drill contractors using either a Reflex gyroscopic tool with readings every 10m after drill hole completion or a Reflex electronic multi-shot camera with readings for dip and magnetic azimuth taken every 30m down- hole.

If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Significant drillhole intercepts relating to the Wagga Tank Open Pit MRE have been compiled, with a summary of all information in Table 9 in Appendix A. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. |
No top cuts have been applied when reporting exploration results. Significant intercept cut offs for exploration results reporting: 0.8% CuEq. Copper equivalent grades based on copper, gold, silver, lead and zinc prices of A$14,458/t, A$3,647/oz, A$43.90/oz, A$3,283/t and A$4,267/t respectively. Metallurgical metal recovery assumptions for the Oxide, Transition and Fresh zones are 85/65/45% for Cu, 85/73/61% for Au, 85/81/77% for Ag, 0/39/78% for Pb, 0/45/90% for Zn, and are based on metallurgical testwork completed at ALS Burnie. In the Company’s opinion, all metals included in the copper equivalent grades have reasonable potential to be recovered and sold. Copper contributes the most metal to the equivalent calculation. These parameters give the following formulae: Oxide: CuEq (%) = Cu (%) + 0.811 x Au (g/t) + 0.0098 x Ag (g/t) Transition: CuEq (%) = Cu (%) + 0.911 x Au (g/t) + 0.0122 x Ag (g/t) + 0.136 x Pb (%) + 0.204 x Zn (%) Fresh: CuEq (%) = Cu (%) + 1.099 x Au (g/t) + 0.0167 x Ag (g/t)+ 0.394 x Pb(%)+ 0.59 x Zn(%) |

The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology. |
The majority of the Southern Nights-Wagga Tank area is overlain by surficial cover, with only minor bedrock exposures in the Wagga Tank area. Geological interpretation is primarily based on geological logging of diamond and RC drill holes. The geological stratigraphic model built for the Maiden MRE in June 2019, was built utilising 385 drill holes within the Wagga Tank deposit and 381 drill holes (inclusive of RAB) within the Southern Nights deposit. Due to the infill nature of the recent Mineral Resource drilling the geological stratigraphic model was reviewed and updated for the current Wagga Tank MRE. The base of surficial soils and clays ranges from around 0.50 m thick in the mineralised zone to locally around 7 m in peripheral areas. The oxide zone, which, within the resource pit shell averages around 80 m thick, is underlain by a transition zone averaging around 60 m thick with fresh rock occurring at an average depth of around 150 m. Open pit resource modelling incorporates a NE (035) trending, subvertical envelope capturing continuous zones of composited copper equivalent grades of greater than approximately 0.1 g/t, which is subdivided into a generally higher grade, more continuously mineralised contact zone, and an eastern domain of more variable, commonly lower grade mineralisation, which is commonly not developed within the oxide zone. The contact zone is consistent with, and somewhat wider than mineralised domain utilised for underground resource modelling and is proximal to the contact between the volcaniclastic breccias and sandstones of the Vivigani Formation and overlying Wagga Tank Mudstone. |

The combined mineralised envelope used for open pit resource modelling is interpreted over around 470 m of strike and extends from the base of surficial material to around 560 m depth. The contact zone averages around 23 m thick, with horizontal widths of the eastern zone averagingaround 30 m. |

Copper, gold, silver, lead and zinc grades estimated by Ordinary Kriging of two m down hole grades with upper cuts selected by mineralisation domain and oxidation zone and generally approximating the 99.5thpercentile of each dataset. For the oxide eastern zone zinc composite grades, which do not directly contribute to estimated resources are generally low grade (averaging 0.03%) and this zone was estimated without upper cuts. Upper cuts were applied to oxide, transition and fresh portions respectively of the eastern zone as follows: • Cu %: 1.4,3.0 and 2.4 • Au g/t: 3.5,30 and 2.5 • Zn %: 0.4,2.5 and 6.6 • Pb %: 1.4,30 and 2.4 • Ag g/t: 70,80 and 60 Upper cuts were applied to oxide, transition and fresh portions respectively of the contact zone as follows: • Cu %: 6.5,6.5 and 6.5 • Au g/t: 8.0,5.0 and 5.0 • Zn %: Uncut,21 and 21 • Pb %: 6.0,15 and 15 • Ag g/t: 650,700 and 700 Indicated mineral resources are extrapolated to a maximum of around 20 m from drilling with around 95% within 15 m of drilling. Inferred mineral resources are extrapolated to a maximum of around 50 m from drilling with around 93% within 30 m of drilling. Micromine software was used for data compilation, domain wire-framing, and coding of composite values, and GS3M was used for Mineral Resource estimation.

| Description of how the geological interpretation was used to control the resource estimates. |
Resource modelling incorporates a NE (035) trending, subvertical envelope capturing continuous zones of composited copper equivalent grades of greater than approximately 0.1 g/t, which is subdivided into a generally higher grade, more continuously mineralised contact zone, and an eastern domain of more variable, commonly lower grade mineralisation, which is commonly not developed within the oxide zone. The domains were subdivided by oxidation zone for assignment of upper cuts. These domains are consistent with geological understanding. |

Estimation of metal grades generally included upper cuts selected by mineralisation domain and oxidation zone and generally approximating the 99.5th percentile of each dataset.

Peel routinely Peel routinely performed immersion density measurements on air dried samples of drill core with results available for 941 intervals of Wagga Tank drill core ranging in length from 0.06 to 0.77m and averaging around 0.24m. Immersion density measurements are available for around 16% of the combined composite estimation dataset. The remaining assayed composites from the transition and fresh zone were assigned densities from sulphur assay grades using functions derived from composites with both measurements as follows: • Transition: Density (t/m3) = 2.60 + 0.022 x S(%), to a maximum of 4.5 t/m3. • Fresh: Density (t/m3) = 2.70 + 0.041 x S(%), to a maximum of 4.5 t/m3. These functions represent an association between increasing density and sulphur grade reflecting increasing concentration of sulphide minerals . Oxide zone model blocks were assigned a density of 2.50 t/bcm on the basis of immersion density measurements of diamond for this zone. Densities were assigned to transition and fresh model blocks by Ordinary Kriging of drill hole composites with density values assigned to composites from immersion measurements or density versus sulphur functions for composites without density measurements and with sulphur assays. The un- mineralised surficial zone which does not inform mineral resources was assigned a density of 1.8 t/bcm on the basis of the competent person’s experience of similar material. For a comparatively small portion of the Wagga Tank mineralised envelope where diamond core shows numerous cavities and low-recoveries, assigned densities were factored by 40% reflecting average core-recoveries for this zone.

The majority of the Southern Nights-Wagga Tank area is overlain by surficial cover, with only minor bedrock exposures in the Wagga Tank area. Geological interpretation is primarily based on geological logging of diamond and RC drill holes. The geological stratigraphic model built for the Maiden MRE in June 2019, was built utilising 385 drill holes within the Wagga Tank deposit and 381 drill holes (inclusive of RAB) within the Southern Nights deposit. Due to the infill nature of the recent Mineral Resource drilling the geological model was reviewed and it was considered unnecessary to update the stratigraphic model for the current MRE. The base of weathering has been modelled using information from the drill logs. The downhole points of the top of fresh rock surface have been used to create an oxidation bounding surface for the deposit. Due to the infill nature of the recent Mineral Resource drilling the oxidation surface used in the maiden MRE, was reviewed and it was considered unnecessary to update the stratigraphic model for the current MRE. Minor supergene mineralisation is located above this oxidation surface and has not been considered as part of this MRE. The base metal mineralisation at Southern Nights has been interpreted to be sub-parallel to the stratigraphy which dips steeply to the west. The base metal mineralisation at Wagga Tank is more structurally complex and has been interpreted to be sub-vertical with a slight dip to the east in some places.

These domains are consistent with geological interpretations, and comprise the following: Main contact zones at Southern Nights and Wagga Tank proximal to the contact between the volcaniclastic breccias and sandstones of the Vivigani Formation and overlying Wagga Tank Mudstone. The Southern Nights contact zone includes three internal zones capturing higher grade, massive sulphide mineralisation with zinc grades of nominally greater than 17.5%. These zones represent around 3% of the interpreted contact zone domain volume. One main and four subsidiary eastern zones at Southern Nights within the Vivigani Formation. |

| Dimensions | The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
Southern Nights mineralised domains trend north south and dip at around 85otowards the west. The contact zone is interpreted over approximately 1.6km of strike with widths ranging from around rarely 2 to 28m and averaging around 5.5m. The domain extends from the base of oxidation at approximately 110m depth to around 650m depth. The main eastern Southern Nights domain is interpreted over approximately 480m of strike from around 170 to 540 m depth with an average width of around 4.7m. The four subsidiary eastern domains, which contribute around 2% of Mineral Resources range in strike from around 50 to 200m, with average widths of around 2.7m. The Wagga Tank mineralised domain trends north- east (035o) over around 330m of strike, and dips at around 85otowards the east with average widths of around 6m. Mineral Resources are constrained to $60/t, $80/t and $100/t NSR optimal stope shapes, generated with minimum widths of 3m, excluding small peripheral zones. The Southern Nights Mineral Resource estimates extend over around 1,400m of strike from around 110m to 640m depth. The Wagga Tank estimates are truncated by the approximately 240-metre-deep pit constraining open pit mineral resources extending over around 330m of strike from around 150m to |

| Estimation and modelling techniques |

If a computer assisted estimation method was chosen include a description of computer software and parameters used. |
Zinc, lead, copper, silver and gold grades were estimated by Ordinary Kriging of 1m down-hole composited assay grades within the mineralised domains. Density was also estimated by Ordinary Kriging, with composites without density measurements assigned densities from sulphur, or less commonly zinc assays. Zinc, lead and silver grades, which are strongly positively correlated with density, were estimated by Kriging of metal grades multiplied by density, and metal grades back calculated. Copper and gold grades were directly Kriged. Estimation of each attribute included upper cuts which generally approximate the 99thpercentile of each dataset. Upper cuts applied to the Southern Nights Low grade contact, High grade contact, eastern zones and Wagga Tank domains respectively were as follows: • Zn %: 20, 53, 15 and 27 • Pb %: 12, 25, 5 and 19 • Ag g/t: 700, 800, 200 and 750 • Cu %: 3.5, 2.5, 2.5 and 5.5 • Au g/t: 5, 6, 2.5 and 7 Estimates are generally extrapolated to a maximum of around 40m from drill intercepts. Micromine software was used for data compilation, domain wire-framing, and coding of composite values, and GS3M was used for Mineral Resource estimation. The estimation technique is appropriate for the mineralisation style. |

Drill hole intercept spacing varies from around 20 by 20m and locally tighter in central areas of the mineralisation to greater than 80 by80 m in peripheral areas and at depth. Estimation included an eight six-pass octant-based search strategy, with ellipsoids aligned with mineralised domain orientations. Search ellipsoid radii (across strike, along strike, down dip) and minimum data requirements for these searches comprise: Search 1: 30,30,8 m; Minimum 8 data, 2 octants, maximum 16 data Search 2: 60,60,16 m; Minimum 8 data, 2 octants, maximum 16 data Search 3: 60,60,16 m; Minimum 4 data, 1 octant, maximum 16 data Search 4: 120,120,24 m; Minimum 4 data, 1 octant, maximum 16 data Search 5: 240,240,48 m; Minimum 4 data, 1 octant, maximum 16 data Search 6: 240,240,48m; Minimum 4 data, 1 octant, maximum 16 data Blocks informed by search passes 1 to 3 provide the majority of combined Indicated Mineral Resources, and search passes 1 to 4 estimates dominate Inferred Mineral Resources. |

Mineral Resources are constrained within a series of mineable shapes were produced by Deswik's Shape Optimiser (SO) using NSR parameters compiled by Peel. The NSR estimation takes into account metallurgical recovery assumptions derived from metallurgical testwork results. It also takes account of the metal payabilities, metal prices, exchange rates, freight and treatment charges and royalties. The metal recoveries and metal prices used in the NSR estimation are found in the main body of this announcement. |
| Mining factors or assumptions |
Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
Mineral Resource estimates are reported within optimal stope shapes generated at NSR cut offs of $A60/t, $A80/t and $A100/t. Material at these cut-offs are considered by Peel to have reasonable prospects of extraction. The smallest mineable unit (SMU) for the SO shapes is 5 m long by, 5m high, with a minimum mining width of 3m. No Hangingwall or Footwall dilution was applied to the Mineral Resource shapes however internal dilution has been included where required. No minimum pillar has been designed between the stope shapes zones to capture as much mineralisation as possible. The assumption is cemented fill could be used to recover the mineralisation, so no pillar is required. For each domain, estimates for a small number of peripheral mineable shapes, distal to the main grouping were excluded from the MRE. |

| Metallurgical factors or assumptions |
The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
Metallurgical testwork completed by Peel, primarily undertaken at ALS Burnie, has guided the metallurgical recoveries assigned to the Wagga Tank Pit Constrained MRE. Work to date has comprised series of sequential and locked cycle flotation tests, as well as cyanide leach and gravity recovery for gold/precious metals, and acid leach for oxide copper minerals. Metallurgical testwork remains ongoing. |
| Environmen- tal factors or assumptions |
Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
Economic evaluation of the project is at an early stage, and environmental considerations for potential mining have not yet been evaluated in detail. Information available to Peel indicates that there are unlikely to be any specific environmental issues that would preclude potential eventual economic extraction. |
| Bulk density | Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
Peel routinely performed immersion density measurements on air dried samples of drill core with results available for 4,626 intervals ranging in length from 0.04 to 0.77m and averaging around 0.25m. Immersion density measurements are available for around one quarter of the combined composite estimation dataset. The remaining composites were assigned densities from sulphur or less commonly zinc assay grades for rare intervals without sulphur assays. The sulphur vs density function was derived from composites with both measurements: Density (t/m3) = 2.60 + 0.047 x S(%), to a maximum of 4.5 t/m3. This reflects an association between increasing density and sulphur grade reflecting increasing concentration of sulphide minerals. The zinc vs density function was derived from composites with both measurements: Density (t/m3)= 2.92 + 0.047 x Zn(%),to a maximum |

| of 4.5 t/m3. For a comparatively small portion of the Wagga Tank mineralised domain where diamond core shows numerous cavities and low-recoveries, assigned densities were factored by 40% reflecting average core-recoveries for this zone. The available information suggests that the density measurements are representative of the mineralisation. |
||
| Classification | The basis for the classification of the Mineral Resources into varying confidence categories. |
Estimated Mineral Resources are extrapolated to generally around 40m from drill intercepts and classified as Indicated and Inferred on the basis of polygons defining areas of relatively consistent drill hole spacing. For the Southern Nights and Wagga Tanks contact zone domains, estimates for mineralisation with consistently 40 by 40m or closer spaced sampling are classified as Indicated and estimates for more broadly sampled mineralisation are initially classified as Inferred. The interpreted low recovery/cavity zone at Wagga Tank was re-classified to Inferred. The eastern Southern Nights domains are comparatively broadly drilled and all estimates for these domains are classified as Inferred. |

The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. |
