PRIORITY TARGETS DEFINED AT LAMMERLAW GOLD PROJECT

Detailed desktop study validates Lammerlaw’s prospectivity and outlines clear, low-cost pathways for staged exploration ahead of NZP&M permit transfer approval.

  • Desktop study completed at the Lammerlaw Gold Project – New Zealand , ahead of anticipated permit transfer approval by New Zealand Petroleum and Minerals (NZP&M).

  • Lammerlaw is situated within a regionally developed structural corridor in Central Otago Goldfields, with documented historical gold production but limited modern exploration .

  • Three priority targets have been defined - Devils Creek (historic hard rock gold workings), Stony Creek (geophysics supported Au–W–Sb system), and the prospective TZ3–TZ4 Structural Boundary.

  • Extensive historical alluvial workings reported gold grades of up to 2.72 g/t Au , rock chip tungsten samples returning up to 710 ppm W , and stream sediment anomalies up to 340 ppm W collectively support the interpretation of an orogenic gold system developed within structurally controlled shear zones.

  • Lammerlaw complements the NZ flagship Cap Burn Gold Project, adding portfolio depth and exploration optionality through lowcost, staged groundbased evaluation of priority targets .

  • Assay results from the recently completed Cap Burn RC drilling program are expected in early March , subject to New Zealand laboratory turnaround time.

Critical Resources Limited (‘ Critical Resources’ or the ‘ Company ’, ASX : CRR ) is pleased to advise the completion of a detailed desktop study over the Lammerlaw Gold Project (‘Lammerlaw’) located in New Zealand’s Central Otago Goldfield . The study was undertaken to refine geological understanding, assess regional prospectivity, and generate prioritised targets for future field programs, supporting the Company’s staged work program ahead of the anticipated approval for the transfer of the permit interest by NZP&M .

The desktop review identifies three priority target areas at Lammerlaw, which is positioned within a regionally developed structural corridor with documented historical gold production but limited modern exploration. The Project lies on the southwestern flank of the Central Otago Antiform ( Figure 1 ), which hosts OceanaGold’s >10 Moz Macraes gold camp . Lammerlaw forms part of the Company’s broader strategy to build a scalable gold portfolio in Otago—a region anchored by the Macraes operation and demonstrating renewed exploration success, including Santana Minerals’ Bendigo–Ophir discovery.

LAMMERLAW PROJECT — DESKTOP STUDY

Lammerlaw covers approximately 410 km² and lies ~50 kilometres south-south-west from the Company’s Cap Burn Gold Project, with both projects situated within the broader Central Otago gold province and along related regional structural corridors of the Otago Schist Belt. The regional setting of the Central Otago Schist Belt is highly supportive of orogenic gold systems; the northeastern flank of the broader antiform hosts

‑ OceanaGold’s >10 Moz Au Macraes Mine ( Figure 1 ), a well documented geological model for shear‑controlled mineralisation in the Otago Schist Belt.

Host rocks within Lammerlaw comprise Textural Zone 3 and 4 schists (TZ3, TZ4), which are known to host low‑angle, shear‑zone‑controlled deposits such as Macraes and Santana Minerals’ (ASX:SMI) Bendigo–Ophir project. Importantly, the geological review references published structural work identifying a potential ‘mirror image’ of the Hyde–Macraes Shear Zone in southern Otago coincident with the Lammerlaw permit area. The TZ3–TZ4 transition represents a rheological and metamorphic contrast within the Otago Schist Belt. Such contrasts are known to localise strain during regional deformation, promoting development of low angle shear zones and associated fluid pathways. This supports the potential for orogenic gold mineralisation within an analogous structural setting, noting that this interpretation remains conceptual pending field validation.

The simplified schematic cross section (modified from Mackenzie et al., 2017) illustrates the structural symmetry of the Otago Schist Belt and the interpreted position of lower greenschist facies schists prospective for shear hosted orogenic gold mineralisation.

Extensive historic alluvial gold workings have been identified across the Lammerlaw permit area through the review of aerial imagery and LiDAR data. These workings highlight widespread gold dispersion across multiple drainage systems and are interpreted to indicate the presence of proximal bedrock gold sources within surrounding structural corridors. The distribution and density of these alluvial workings are consistent with a structurally controlled orogenic gold system developed within the permit area.

Historical records also identify several hard rock prospects and late 19th to early 20th century mine workings within the Lammerlaw permit area, each associated with lode or vein-style mineralisation. These include Fiddlers Lode, Devils Creek, Bootlemans and Boatman’s (Figure 2) . The desktop review notes Devils Creek as the most historically developed prospect , with two small adits and numerous pits and trenches confirmed through aerial imagery and LiDAR interpretation.

==> picture [524 x 371] intentionally omitted <==

Figure 2 – Lammerlaw permit showing locations of prospect targets and historic mine workings.

Historic reports describe a stamping battery operating in the late 1890s at Bootlemans, with modern geochemical sampling highlighting tungsten anomalies in stream catchments up to 340 ppm W , suggesting multi commodity potential. Tungsten is commonly associated with orogenic gold systems and can highlight ‑ structurally fertile zones, supporting both gold potential and multi commodity upside.

The desktop review also notes legacy rock chip samples grading 2.72 and 2.58 g/t Au and stream sediment sampling with elevated gold, arsenic and tungsten profiles , supporting multiple target areas.

Outside the Lammerlaw permit, and highlighting the fertility of the region, sits the Otago Pioneer Quartz ( OPQ ) Mine, located along the OPQ structural trend and currently held by New Age Exploration Limited (ASX:NAE). OPQ is one of the earliest hard‑rock gold operations established in the Otago region following its discovery in the 1860s. Historic records indicate the OPQ reef was mined over a strike length of more than 1,200 metres, with reported average historic grades of approximately 13–15 g/t Au, demonstrating the presence of historically high grade gold mineralisation along this structural corridor, which extends toward the Lammerlaw permit area.

Target Generation and Priority Areas

The desktop study has defined three priority target areas within the Lammerlaw permit that are considered highly prospective for structurally controlled gold (and associated tungsten) mineralisation. Target generation has been guided by the integration of historic mining records, modern aerial imagery and LiDAR interpretation, regional geochemistry, and available airborne geophysical data . The desktop study outlines three prospective structural themes relevant to the broader area:

  • OPQ Trend (Target 1): Historic gold mining Fiddlers Lode, Devils Creek, Bootlemans and Boatman’s with reported historic grades and high rock chip values in historic reports.

  • Stony Creek Trend (Target 2): Associated with historic antimony workings, including reported test shipments grading 47% Sb and references to very high grade ore potential in historic records.

  • TZ3–TZ4 Structural Boundary (Target 3): Interpreted boundary between Textural Zone 3 and 4 schists traversing the permit area and representing a regionally significant structural corridor prospective for shear hosted orogenic gold mineralisation.

==> picture [122 x 43] intentionally omitted <==

DEVILS CREEK TARGET – HISTORIC WORKING

The Devils Creek ( Figure 3 ) area represents the most advanced historic hard rock gold prospect within the Lammerlaw permit and is a key focus of the desktop review. Historic records describe two small adits developed along strike on either side of Devils Creek , supported by numerous pits and prospect trenches. Interpretation of high resolution aerial imagery and LiDAR digital terrain data confirms the presence and continuity of these historic workings and allows the inferred strike of the mineralised lode to be mapped with greater confidence.

The alignment of historic underground development, surface excavations, and mapped workings suggests mineralisation localised along a coherent shear or lode structure rather than isolated quartz vein occurrences , consistent with lode style mineralisation developed within the Otago Schist Belt. The inferred strike extent derived from desktop interpretation provides a clear framework for follow up exploration, with proposed first pass surface sampling designed to test along strike continuity and assess potential extensions beyond the historically worked areas. Devils Creek is considered a priority target as it combines:

  • Direct evidence of historic hard rock gold exploitation;

  • A clearly identifiable structural trend mapped through modern datasets; and

  • A location consistent with shear controlled mineralisation typical of Otago orogenic gold systems.

As such, Devils Creek represents a high priority exploration target with demonstrated structural continuity and direct evidence of historic hard rock gold mineralisation, providing a strong platform for systematic follow up work.

STONY CREEK – GEOPHYSICS TARGET

Target Two is defined along the Stony Creek Trend , which is characterised by a combination of historic antimony workings, elevated tungsten geochemistry, and a distinct electromagnetic response evident in regional airborne geophysical data ( Figure 4 ).

Historic records from the Stony Creek area document antimony production , including reported test shipments of exceptionally high-grade material. While gold production from this trend was limited historically, the presence of antimony and tungsten is considered highly relevant, as both elements are recognised pathfinders in orogenic gold systems , commonly associated with deep-seated, structurally focused mineralising fluids.

The desktop review highlights a coherent linear feature created by electromagnetic contrast coincident with the Stony Creek Trend, interpreted to reflect lithological or structural variations potentially associated with mineralised shear zones. This geophysical signature, when considered alongside historic mining activity and anomalous tungsten values recorded in the broader catchment, elevates the Stony Creek Trend as a compelling exploration target with multicommodity potential . The Stony Creek target is prioritised due to:

  • The coincidence of historic antimony workings with modern geophysical anomalies;

  • The presence of tungsten anomalies consistent with structurally focused orogenic gold mineralisation; and

  • Interpreted structural continuity over a kilometre-scale corridor.

Importantly, the Stony Creek Trend represents a target that was not systematically evaluated using modern exploration techniques , providing scope for new discoveries under shallow cover or along extensions of historically known mineralisation. Together, the Devils Creek and Stony Creek targets demonstrate two complementary expressions of mineralisation within the Lammerlaw permit. These targets form the foundation

for staged follow-up programs , beginning with surface validation and progressing toward more advanced work as warranted. The identification of multiple target styles within the permit reinforces Lammerlaw’s role as a portfolio-depth asset , providing optionality and flexibility in the allocation of exploration capital alongside CRR’s NZ flagship Cap Burn project.

==> picture [524 x 370] intentionally omitted <==

Figure 4 – Regional electromagnetic geophysics dataset covering the Lammerlaw permit with targets outlined.

Critical Resources Managing Director, Tim Wither, commented: ‘ Lammerlaw was secured on the strength of its geological prospectivity, and the detailed desktop study has now validated that decision. The work confirms well-defined shear corridors and, importantly, multiple structurally coherent target areas consistent with orogenic gold systems in the Otago Schist Belt. These refined targets provide a clear foundation for systematic, low-cost field programs designed to test the structural interpretations and advance our understanding of the permit area. Lammerlaw complements Cap Burn and supports our strategy of building opportunities across a proven and highly prospective gold province in New Zealand.’

NEXT STEPS

Following completion of the desktop study, the Lammerlaw Gold Project has been progressed to a stage where ground-based evaluation can be efficiently staged , subject to the granting of the NZP&M permit transfer.

Near-term work will be focused on validating and refining the two priority target areas Devils Creek and Stony Creek, identified through the desktop review, with an emphasis on low-cost, high-information activities

==> picture [122 x 43] intentionally omitted <==

designed to advance geological understanding prior to any more intensive exploration. Initial follow-up work is expected to include:

  • Ground reconnaissance and mapping across the Devils Creek and Stony Creek areas to confirm interpreted structural trends, lithological boundaries, and the location and condition of historic workings identified through aerial imagery and LiDAR interpretation.

  • Targeted surface sampling (including rock chip and soil / water sampling where appropriate) along the inferred strike of the Devils Creek lode and across structural corridors associated with the Stony Creek Trend, aimed at confirming gold and tungsten pathfinder geochemistry.

  • Ground-truthing of geophysical targets , particularly the electromagnetic feature defined at Stony Creek, to assess its relationship to mapped structures, lithology and historic mineralisation.

  • Refinement of the geological model through integration of new field data with the existing desktop interpretation to further prioritise target areas for subsequent exploration stages.

These activities are designed to follow a staged, capital-disciplined exploration approach, consistent with the strategy being applied across its Otago portfolio. Early-stage programs will be used to rapidly screen targets and focus expenditure on the most prospective structural zones, with progression to more advanced work contingent on results.

The Devils Creek and Stony Creek targets offer complementary exploration opportunities:

  • Devils Creek provides a direct pathway to validating historic hard rock gold mineralisation along a mapped structural trend.

  • Stony Creek offers potential for structurally controlled gold associated with tungsten and antimony pathfinder signatures, supported by geophysical data and limited modern exploration.

Lammerlaw’s advancement through low-cost technical work and targeted field programs is intended to complement the Company’s NZ flagship Cap Burn Gold Project , providing additional optionality and flexibility in exploration sequencing. Together, the prospecting permits support the Company’s objective of building a scalable, multi-asset portfolio in New Zealand, with the ability to allocate capital effectively as geological understanding and results evolve.

Exploration
done by
other parties
Acknowledgment and appraisal of
exploration by other parties.

Exploration within the Lammerlaw permit area has historically been
limited and largely reconnaissance in nature. Most modern exploration
programs were broad-spaced regional surveys rather than systematic,
prospect-scale investigations.

Lime and Marble Ltd (1972; MR2102): Conducted early geochemical
sampling, including a soil survey around Waipori, and reviewed historic
data.

BHP (1988; EL33305/MR2126): Sampled 229 stream sediments and 29
rock chips near the eastern boundary of the permit. Results showed
anomalous Au in stream sediments and elevated Au Sb W in mine dump
rock chips.

Welcome Gold Mines (1995; PP39039/MR3392): Collected 345 BLEG,
rock chip, and stream sediment samples within the PPA. Anomalous
gold results were reported; however, no systematic follow up drilling or
detailed geochemical infill programs were completed.

Various Operators (1988–2007; HPD NZ, Newmont): Collected <200
stream sediment and rock chip samples across and adjacent to the
area. Some gold anomalies were identified but not pursued. No
systematic soil sampling was undertaken.

Glass Earth Gold (2007–2010; PP39322/MR4666): Held tenements over
the entire PPA. Activities included airborne geophysics, limited
soil/stream/chip sampling, and mapping, though most of this was
focused to the northeast (Rock and Pillar Range) and northwest
(Serpentine Flat). No significant anomalies were returned within the
current PPA. Legacy data compilation was completed.

Lammer Resources Ltd (2022–2024; MR7162): Carried out soil sampling
over the northeastern part of the PPA. Identified mineralisation trends
and terrane boundaries, but results were not sufficiently encouraging to
justify further work and the area was relinquished.

These historical efforts highlight the presence of localised gold and
pathfinder anomalies but confirm the lack of systematic modern
exploration, particularly within the core of the permit area.

In 2007 (MR4325) Glass Earth (NZ) Ltd conducted a regional airmag / EM
survey over central Otago which covered the present permit.

Collectively, historic exploration confirms the presence of localised gold
and pathfinder element anomalies (Au–Sb–W), but highlights the
absence of systematic soil geochemistry, structural mapping, or drill
testing within the core structural corridors of the current permit area.
Geology Deposit type, geological setting
and style of mineralisation.

The Lammerlaw Project lies across and south of the regional boundary
between the Caples and Torlesse terranes within the Otago Schist Belt,
a critical contact zone associated with regionally significant
metamorphism and deformation. The permit is underlain predominantly
by greenschist facies Caples Terrane metasediments (TZ3), and is
structurally situated on the southern limb of a broad antiform. The
Caples–Torlesse boundary is interpreted to play a key role in focusing
deformation and fluid flow, with mapped shear zones and late quartz
veining commonly associated with arsenopyrite, stibnite, scheelite, and
minor gold. These features, combined with the analogous metamorphic
setting to the Hyde–Macraes Shear Zone, are consistent with structural
and metamorphic settings known to host Macraes-style orogenic gold
mineralisation within the Otago Schist Belt.

Other exploration data, if
meaningful and material, should
be reported including (but not
limited to): geological
observations; geophysical survey
results; geochemical survey results;
bulk samples – size and method of
treatment; metallurgical test results;
bulk density, groundwater,
geotechnical and rock
characteristics; potential
deleterious or contaminating
substances.

Publicly available historic reports (MR2102, MR2126, MR3392, MR4666,
MR7162 ) academic publications (MacKenzie et al., 2016) document
