Exploring for hidden Goldfields in the Laverton Tectonic Zone

Pinjin Gold Project

Located 140 km east-northeast of the City of Kalgoorlie-Boulder, KalGold’s Pinjin Project is hosted within the NW-SE trending regional structural domain known as the Laverton Tectonic Zone (LTZ). The LTZ hosts over 20 significant gold deposits including Sunrise Dam, Wallaby, Granny Smith, Red October, Anglo Saxon, Rebecca and several gold fields which cumulatively contain more than 30 million ounces of gold.

However, the southern part of the Laverton Tectonic Zone (and neighbouring Celia Tectonic Zone) is less explored than the northern area, largely due to poorer outcrop. KalGold believes this is why some of the largest discoveries in recent years, like Rebecca (Ramelius Resources ASX: RMS) and Lake Roe (Breaker Resources ASX: BRB), are located in this region.

With KalGold recognising the significant potential of the area to host large-scale gold deposits, the Company has, since listing, focussed on building a ground position in the area. KalGold aims to continue to establish a significant land holding in what it believes is one of the most prospective parts of the Eastern Goldfields province.

KalGold’s Gold Exploration Strategy - Discovering hidden goldfields at Pinjin

The south of the Laverton Tectonic Zone mirrors the well-endowed north, where wide North-South zones host >5Moz of gold. Kalgold is systematically exploring their tenements in the South of the Lavertone Tectonic zone, where the north-south structures of the well endowed north are repeated.

• KalGold has already defined a shallow JORC Inferred resource at Kirgella Gift and Providence 2.34 Mt @ 1.0 g/t Au for 76,400 oz – see full MRE table below
• Kalgold hold a large strategic footprint with multi-million once potential
• Numerous targets for testing
• Discoveries from proven exploration technique
• Only ~10% of targets tested to date
• Kalgold work programs expanding

Kirgella Gift & Providence

• An initial JORC Code (2012) Mineral Resource Estimate (MRE) at Kirgella Gift and Providence of 2.34 Mt @ 1.0 g/t Au for 76,400 oz of gold from only 3 m depth (0.5 g/t Au cut-off) was announced 25 July 2024.
• Highly economic discovery with KalGold’s direct exploration expenditure cost (drilling and assay) of only ~A$4.20 per gold ounce.
• The combined Kirgella Gift and Providence MRE is of a similar geometry, mineralisation size and grade to Ramelius Resources Duke deposit at Rebecca, which contains 2.7 Mt @ 1.1 g/t Au for 98,000 ounces of gold (ASX: RMS 14 September 2023).
• Primary gold mineralisation was also identified in RC drilling at Providence South, following up earlier near-surface aircore results (ASX release 19 December 2025).
• First pass diamond drilling program (four diamond holes for 1,154.6 m) completed at Kirgella Gift and Providence and co-funded under the Western Australian Government’s Exploration Incentive Scheme (EIS) (ASX release 13 February 2026).
  • Broad zones of gold anomalism and mineralisation are directly associated with extensive shearing, alteration, and veining. Thick gold intercepts include:
    • KGDD25004:
      • 15 m at 1.75 g/t Au from 26 m, including 6 m at 2.74 g/t Au from 28 m
        and 1 m at 3.09 g/t Au from 38 m
      • and 4 m at 2.72 g/t Au from 50 m, including 2 m at 4.59 g/t Au from 51 m
      • and 28 m at 2.24 g/t Au from 92 m, including 8.5 m at 3.21 g/t Au from 96 m
        and 9 m at 2.82 g/t Au from 110 m
    • KGDD25003:
      • 4 m at 1.64 g/t Au from 82 m, including 3 m at 2.14 g/t Au from 83 m
      • and broad anomalism of 17 m at 0.29 g/t Au from 32 m (at 0.1g/t cutoff)
  • Primary orogenic gold mineralisation continues to a vertical depth of 300 m beneath surface, deeper than previous RC drilling, extending 160 m below the JORC Code (2012) Inferred MRE.
    • KGDD25001:
      • 10 m at 1.03 g/t Au from 231 m, including 1 m at 2.83 g/t Au from 233 m
        and 1 m at 2.14 g/t Au from 237 m
    • KGDD25002:
      • 2 m at 0.91 g/t Au from 259 m and 6 m at 0.94 g/t Au from 268 m
        within broad anomalism of 21 m at 0.51 g/t Au from 255 m (at 0.1g/t cutoff)
      • and 1 m at 1.18 g/t Au from 350 m
  • Deep intercepts are located at the southern margin of Kirgella Gift. New targets at depth will be tested for vertical continuity and repetition directly beneath the deposit.
• RC drilling completed 21 RC drill holes for 3,702m (ASX release 4 August 2026)
  • Thick zones of shear-hosted gold mineralisation intersected, with alteration, sulphides and veining intervals up to 38m thick from shallow depths. Intercepts include:
    • KGRC26003: 3m at 3.55 g/t Au from 67m, including 1m at 8.57 g/t Au from 67m
      within a broader mineralised envelope of 7m at 1.58 g/t Au from 64m
    • KGRC26008: 28m at 1.15 g/t Au from 20m, including 4m at 2.08 g/t Au from 24m
      within a broader mineralised envelope of 38m at 0.89 g/t Au from 19 m
      and 5m at 1.24 g/t Au from 97m, including 1m at 2.50 g/t Au from 99m
      within a broader mineralised envelope of 11m at 0.85 g/t Au from 91m

    • KGRC26016: 13m at 1.54 g/t Au from 44m, including 1m at 2.40 g/t Au from 44m
      and 2m at 3.71 g/t Au from 54m
      within a broader mineralised envelope of 25m at 0.90 g/t Au from 39m
    • KGRC26018: 7m at 1.39 g/t Au from 160m, including 4m at 2.04 g/t Au from 160m
      within a broader mineralised envelope of 15m at 0.80 g/t Au from 158m
• Gold mineralisation at both deposits extends beyond the current MRE, remaining open at depth and supporting further drilling to define the full extent of mineralisation to underpin a future MRE update.

The main area of historic focus on the new tenure is at Kirgella Gift, around 13 km south of Anglo Saxon pit. Here, thick, high-grade mineralisation was discovered at shallow levels along 250 metres of strike and remains open in all directions.

Kirgella Gift sits within a geological package of strongly sheared magnetic and sulphidic rocks that extend for a length of approximately 5 km. An associated pronounced geochemical anomaly extends over 5 km by 1 km. Gold mineralisation coincides with distinct breaks and demagnetised zones in a magnetic ridge.

Historic drilling at Kirgella Gift (prior to 2011) identified shallow, high-grade gold mineralisation. Impressive results included:

• RC drill hole KGRC004 (drilled in 2011) contained an intercept of 33 m at 3.1g/t Au from 51 m, including:
  • 12 m at 4.66g/t Au from 52 m,
  • 2 m at 7.01g/t Au from 73 m, and
  • 1 m at 14.25g/t Au from 80 m.
• In 1999, discovery aircore drillhole KSR006 returned 32 m at 2.61g/t Au from 13 m, including:
  • 6 m at 2.61g/t Au from 18 m,
  • 5 m at 3.75g/t Au from 27 m, and
  • 7 m at 4.47g/t Au from 37 m.

These holes were drilled by different companies using different drill methods and variable assay suites (with inherently different detection limits and sensitivities).

In 2023, KalGold undertook several phases of RC drill holes, with phase 1 in the vicinity of the above historic holes, which identified broad zones of shearing and alteration contained poly-deformed, zoned, quartz-carbonate(-pyrite) veining approximately corresponding to historic mineralisation intercepts. Visible gold was identified at 50 m depth in drill hole KGRC23002. Cautionary Statement: Visible gold does not provide precise, accurate, or repeatable indications of gold grade. Laboratory assay results are required to determine the widths and grades of any mineralisation reported in preliminary geological logging.

On 25 October 2023, KalGold announced exceptional results from the next phase of RC drilling:

• Shallow, high-grade intercepts at Providence, including:
  • KGRC23008: 11 m at 2.51 g/t Au from 32 m
    including 4 m at 5.63 g/t Au from 39 m
  • KGRC23009: 14 m at 1.32 g/t Au from 125 m
    including 2 m at 4.45 g/t Au from 132 m
• Kirgella Gift intercepts build on historic data at shallow and deeper levels, moving the dataset one step closer to defining a JORC Code (2012) Mineral Resource Estimate.
  • KGRC23007: 11 m at 1.56 g/t Au from 24 m
    including 4 m at 2.98 g/t Au from 27 m
    and 6 m at 1.18 g/t Au from 45 m
  • KGRC23011: 10 m at 1.16 g/t Au from 85 m
    including 1 m at 2.90 g/t Au from 88 m
    and 15 m at 0.98 g/t Au from 166 m
    including 4 m at 2.14 g/t Au from 173 m
  • Multiple lodes evident with gold mineralisation open in all directions.
  • All intercepts are encased within coherent, sub-grade shear zones which assists correlation, interpretation, and targeting.
• Coherent, sheared gold mineralisation also tagged at Kirgella North (KGRC23004: 4 m at 1.50 g/t Au from 93 m), 90 m north of Kirgella Gift.

The Providence prospect is situated only 700 m south of Kirgella Gift and likewise corresponds with demagnetisation on a break in a magnetic ridge. The prospect’s discovery was one of the last actions taken by the previous explorer and was never systematically followed up. Prior RC drilling is limited to only two holes for 290 m. Within these, a significant intercept was defined: 10 m at 2.11g/t Au from 71 m, including 3 m at 3.41g/t Au from 78 m, in KGRC020.

Lighthorse

• Lighthorse is a KalGold-generated, greenfields gold discovery (ASX release 7 February 2025), characterised by:
  • A 200 m wide primary gold target on the discovery section, open down dip.
  • A 600 m strike, parallel to the Laverton Tectonic Zone, open to the northwest and southeast.
  • Crosscutting mineralised structures extending over 800 m, open to the northeast.
  • A footprint larger than either KalGold’s Kirgella Gift or Providence gold deposits
  • No outcrop, and no effective historic drilling.
• Lighthorse is located in the southeast of the Eastern Goldfields, an area which is becoming a focus for gold discovery and development. It is located:
  • 1 km west of KalGold’s Kirgella Gift and Providence gold deposits,
  • 12 km south of Hawthorn Resources’ (ASX:HAW) Anglo Saxon Gold Mine,
  • 22 km northwest of Ramelius Resources’ (ASX:RMS) Rebecca Gold Project,
  • 30 km east of OzAurum Resources’ (ASX:OZM) high-grade gold discovery at Mulgabbie North
• Broader gold mineralisation and alteration over 1.6km strike, associated with:
  • Quartz (+ carbonate) veining
  • Siliceous and sericitic alteration
  • Sulphides
  • Extensive bleaching
  • Supergene enrichment
• Extensive, primary, orogenic gold mineralisation intersected in fresh rock at Lighthorse (ASX release 19 December 2025):
  • Extends north from previous RC drill coverage and now defines over 1,100 m of strike, up from around 600 m strike previously.
  • Confirms that the near-surface ~1,600m long aircore anomalism is sourced from primary orogenic gold mineralisation below, and remains open to the north.
  • Corresponds with a Sub-Audio Magnetic (SAM) magnetometric conductivity (MMC) high that continues beyond the current extent of RC drilling.
• Gold mineralisation is directly associated with extensive shearing, alteration, sulphide mineralisation, and veining logged in intervals up to 35 m thick. These include:
  • KGRC25052: 15 m at 1.14 g/t Au from 84 m, including 11 m at 1.51 g/t Au from 84 m
  • KGRC25058: 35 m at 0.33 g/t Au from 90 m, including 1 m at 1.61 g/t Au from 100 m
    and 3 m at 1.18 g/t Au from 120 m
  • KGRC25050: 35 m at 0.42 g/t Au from 78 m, including 3 m at 0.86 g/t Au from 86 m
    and 9 m at 0.76 g/t Au from 92 m
• Results define a high-quality and extensive target consistent with a substantial gold mineralised system.
• RC drilling completed 19 holes for 3,194m (ASX release 2 September 2026)
  • RC drilling tested key target areas across the Lighthorse prospect and returned the two highest grade individual assay results at Lighthorse, comprising 19.70 g/t Au (KGRC26036, 145-146m) and 16.50 g/t Au (KGRC26025, 55-56m) and incorporated into intercepts quoted below.
  • Mineralisation styles and relationships consistent with Archaean orogenic gold deposits observed, including alluvial gold in near surface transported material overlying a second, northern supergene blanket together with extensive primary orogenic gold mineralisation.
  • Thick zones of vein and shear-hosted gold mineralisation are up to 27m thick from shallow depths. Significant gold intercepts are in nearly all holes, including:
    • KGRC26036: 3m at 9.01 g/t Au from 145m, including 2m at 12.69 g/t Au from 145m
      and 2m at 1.11 g/t Au from 152m
      within a broader mineralised envelope of 22m at 1.58 g/t Au from 145m
    • KGRC26025: 6m at 4.86 g/t Au from 54m,including 3m at 8.82 g/t Au from 55m
    • KGRC26029: 5m at 1.74 g/t Au from 54m, including 3m at 2.34 g/t Au from 55m
      within a broader mineralised envelope of 11m at 1.01 g/t Au from 54 m
      and 8m at 2.27 g/t Au from 94m, including 4m at 4.40 g/t Au from 95m
      within a broader mineralised envelope of 12m at 1.96 g/t Au from 94m
    • KGRC26038: 5m at 2.91 g/t Au from 101m, including 2m at 6.06 g/t Au from 101m
      and 4m at 1.21 g/t Au from 113m, including 1m at 3.07 g/t Au from 115m
      within a broader mineralised envelope of 17m at 1.22 g/t Au from 100m
  • Clusters of gold intercepts over broad thicknesses may represent the periphery of more significant mineralisation, with several targets identified for follow-up exploration.
• For details of earlier drilling results at Lighthorse, see ASX release 7 February 2025, ASX release 15 April 2025, ASX release 15 July 2025.

• Thick RC intercepts beneath cover, correspond with conductivity highs
• Results are evidence of a large-scale gold-mineralised system
• Wide spaced drilling has only started to understand the full extent of gold at Lighthorse

Wessex

The Wessex and Harbour Lights prospects are located on tenure to the south of the Anglo Saxon gold mine at Pinjin South.

• Gold in historic drilling to tenement boundary next to Anglo Saxon gold mine (HAW)
• Both prospects are hosted by the sheared volcano-sedimentary sequence that constitutes the Laverton Tectonic Zone at Pinjin. Mineralisation is associated with quartz-carbonate veining and alteration selvages at both prospects, similar to that at Anglo Saxon to the north and Kirgella Gift to the south.
• The Wessex prospect shows evidence of being part of the broader Anglo Saxon gold mineralised system, with Hawthorn Resources’ (ASX:HAW) open pit mine located less than 1 km from the drill program.
• 2km long, thick, shallow gold mineralisation defined by KalGold aircore programs (ASX release 23 May 2024, ASX release 9 October 2024).
  • PSAC24001: 28 m at 1.27 g/t Au from 36 m
    including 8 m at 1.90 g/t Au from 44 m and 8 m at 2.15 g/t Au from 56 m
  • PSAC24029: 12 m at 1.17 g/t Au from 52 m
    including 4 m at 3.07 g/t Au from 56 m
  • PSAC24072: 4 m at 2.06 g/t Au from 52 m
    including 3 m at 2.69 g/t Au from 52 m
  • PSAC24067: 16 m at 0.77 g/t Au from 28 m
    including 4 m at 2.37 g/t Au from 28 m
  • PSAC24065: 8 m at 0.94 g/t Au from 36 m
    including 4 m at 1.72 g/t Au from 36 m
• Primary gold mineralisation was also identified in RC drilling at Wessex, following up earlier near-surface aircore results (ASX release 19 December 2025).

Other Pinjin prospects

T12 Prospect

The T12 Prospect lies 1.5 km north of Kirgella Gift and was defined by Newmont in 2008.

A number of anomalous aircore and RAB end of hole anomalies were followed up by RC or DD drilling. However, follow-up drilling failed to identify anomalies at depth and the vast majority of these anomalies were cancelled.

The most significant DD intersection included 5.9 m @ 7.2 g/t Au from 89.7 m in NEWPJDD0001. The interval is reported to be within a near vertical quartz-chlorite-carbonate-chalcopyrite-pyrite vein.

However, follow up diamond drilling to the immediate north and south of NEWPJDD0001 by Newmont and later by Renaissance reportedly failed to reproduce the high-grade results. A number of additional aircore anomalies remain to be followed up, including 6 m @ 1.4 g/t Au from 93 m (NEWPJAC0044).

T15 Prospect

The T15 Prospect lies on E28/2654 and is located 1.5 km southwest of Kirgella Gift.

Renaissance conducted reconnaissance aircore drill testing of the prospect in 2011 with results confirming the presence of significant anomalous gold. A total of 47 aircore holes were completed following up anomalous gold identified by historical Newmont drilling.

All holes were drilled vertically on a broad grid spacing of 50 m x 100 m. The aim of the program was to drill to blade refusal, through the transported regolith and into the underlying bedrock.

Fourteen holes intersected anomalous gold (+100 ppb Au) beneath transported overburden in weathered bedrock, with the program identifying a significant bedrock gold anomaly covering ~600 metres in strike that remains open to the north and south and potentially several hundred metres in width.

First pass drill results included:

• PJAC0552: 2 m @ 9.98g/t gold from 72 m
• PJAC0554: 2 m @ 8.47g/t gold from 93 m
• PJAC0524: 5 m @ 1.12g/t gold from 70 m

At the time, Renaissance reported it was extremely encouraged by the initial results and was planning a follow up drilling program that would include step out and further infill aircore drilling and some deeper holes.

However, there was limited deeper follow-up RC and DD drilling due to Renaissance’s refocus on high-grade gold exploration in Cambodia. Of note, scissor diamond holes below aircore hole NEWPJAC00465 (4 m @ 1.1 g/t Au from 94 m) failed to show any primary gold mineralisation.

There are several other aircore anomalies that have not had follow up drilling with deeper RC, including 1 m @ 30.1 g/t Au in NEWPJAC0229 from 90 m.

Rebecca West

The Rebecca West tenure lies between the Pinjin Mining Centre and Ramelius’s Rebecca Gold Project. E28/3135 is located only 1.5 km west of the Rebecca Project tenure, and only 9 km west of the proposed Rebecca gold processing plant site.

The tenure is peripheral to (but does not include) an internal granite within the Laverton Tectonic Zone. Though superficially similar to the Wallaby deposit (northern Laverton Tectonic Zone) in terms of geometry, much more work is required before it can be determined whether any such target exists on the tenure.

Historic exploration on the tenure has been very limited, with only a single line of shallow aircore holes of any note. Preliminary targeting by KalGold has identified a number of structural targets that will require further examination and ranking before exploration can commence.

Jungle Dam prospect

The Jungle Dam prospect is a gold-in-granite prospect located on E31/1119 that was last explored during the 1990s. Anomalism is associated with a rupture within the internal Jungle Dam Granite. That granite has intruded into the supracrustal sequence that has been strongly deformed by the Celia and the Laverton Tectonic Zones. Work is ongoing to identify and digitise all historic datasets.

Additional gold plays are also apparent around the margins of the Jungle Dam Granite and elsewhere in the shear zones that wrap around it.

Though only gold has been explored and assayed historically, the area may also be prospective for lithium.
