Deep Drilling Identifies

Gold Bearing Structure at Tomingley

Perth, Western Australia - Alkane Resources Limited (ASX: ALK; TSX: ALK; OTCQX: ALKRY) (‘Alkane’ or ‘the Company’) is pleased to announce the latest exploration results and drilling for the underground expansion of existing resources at its Tomingley Gold Operations (Tomingley) in New South Wales.

Program Summary

  • Exploration drilling at Tomingley has tested a seismic reflector feature beneath the Roswell Deposit and near-mine prospects such as El Paso. Underground drilling at Roswell, outside of grade control, has focused on improving confidence in the Inferred Resources.

  • Roswell underground resources (1.3g/t Au cut-off) are estimated at 5.5Mt grading 2.6g/t Au for an endowment of 476,000 oz Au[1] . A previous exploration drill hole (RWD061) was extended to 1,392m depth to intersect a seismic reflector identified ~400m below current resources. The drilling identified the east dipping reflector as gold-arsenic enriched hydrothermal breccias and veining.

  • A program of underground drilling at Roswell targeting the Inferred Resources hosted by the Western Monzodiorite domain was completed. Results for this program testing the mid-portion of the domain to a nominal 15m x 20m grid spacing were received from the final 21 drill holes, totalling 4,019m. The program has confirmed multiple high-grade gold zones within the monzodiorite.

  • Exploration drilling of 7 diamond core drill holes at the El Paso prospect and 1 RC drill hole at the Westray prospect. All drilling intersected quartz veining with gold-arsenic mineralisation, hosted in the prospective Mingelo Volcanic stratigraphy.

Assay Highlights

  • Roswell Seismic target (RWD061):

  • 8.7 m grading 1.15g/t Au including 3 m grading 2.78g/t Au;

  • 0.3 m grading 11.4g/t Au;

  • 2 m grading 5.90g/t Au.

  • Roswell Western Monzodiorite underground drilling:

  • 5.9 m grading 31.0g/t Au including 2.1 m grading 78.4g/t Au (ROSUG657D);

  • 17.4 m grading 4.30g/t Au including 2.5 m grading 21.1g/t Au (ROSUG644D);

  • 3.5 m grading 16.1g/t Au including 1.2 m grading 45.1g/t Au (ROSUG425D);

  • 0.6 m grading 69.2g/t Au (ROSUG656D).

  • El Paso exploration drilling:

  • 17 m grading 4.02g/t Au including 0.5 m grading 77.5g/t Au (EPD020);

  • o 8 m grading 2.10g/t Au (EPD020).

Alkane Managing Director & CEO Nic Earner said: “Our continuing exploration at Tomingley reveals both extensions to our deposits, which remain open at depth and along strike, as well as new areas of mineralisation. This drilling demonstrates the significant resource expansion potential across the mine site, we look forward to revealing this potential, both near mine and regionally around Tomingley.”

Tomingley Gold Operations (TGO)

Alkane Resources Ltd 100%

Tomingley Gold Mine is an open pit and underground mining development with a 1Mtpa processing facility in operation since 2014. The development is located near the village of Tomingley, approximately 50 kilometres southwest of Dubbo in Central West New South Wales. Tomingley Gold Operations Pty Ltd is a wholly owned subsidiary of Alkane.

Development at Tomingley has been based on the Wyoming One, Wyoming Three, Caloma, Caloma Two and Roswell gold deposits. To date, mining occurred underground at Wyoming One, Caloma, Caloma Two and Roswell deposits. Roswell stope ore production came on stream in April 2024 (ASX Announcement 22 April 2024) via an approximately 3 km decline from the Wyoming One open cut.

The Tomingley deposits are located within a tightly folded Ordovician volcano-sedimentary sequence that has been altered to a sericite-carbonate-albite-quartz-pyrite-arsenopyrite assemblage, typical of orogenic lode-style gold deposits. Mineralised fluids are interpreted to have been focused by differential strain in and around andesitic volcanics due to the rheological competency contrast between the volcanics and the bounding volcaniclastic sediments. The brittle nature of the volcanics often leads to the development of shear-hosted sheeted quartz vein and breccia deposits within and adjacent to the andesitic bodies. Separately, thin carbonaceous mudstone strata appear to have been a focus for shearing and a chemical trap for gold.

Since underground mining commenced in 2018, extensive underground drilling has been employed to define ore reserves for extraction and maintain exploration to define additional resources. The most recent Reserves and Resources were summarised in the ASX release on 15 October 2025 “NSW Resources and Reserves Statements FY25”.

Roswell

The Roswell underground resources (1.3g/t Au cut-off) are estimated at 5.5Mt grading 2.6g/t Au for 476 oz Au (see table titled TGO Mineral Resources at 30 June 2025 ). The previously deepest exploration drill hole (RWD061 – ASX announcement 17 November 2022 ) at Roswell was completed to 1,002m. This hole was recently extended by another 390m with HQ3 diamond core drilling to intersect a seismic reflector identified by the reprocessed 2D seismic survey data in 2024 (see ASX announcement 7 October 2024 ). This reflector, identified in three 2D seismic traverses, is dipping ~30[o] to the east with more than a 5km strike length, is interpreted to be a major fault or conduit for the upwelling of gold-arsenic enriched hydrothermal fluids to the Tomingley gold system.

The drill hole intersected several hydrothermal breccias, and quartz veining in a similar orientation to the seismic reflector surrounded by an intense silicification alteration halo hosted in volcaniclastic metasediments. Visible gold was observed in one of the breccias. The reflector zone was also characterised by zones of intense arsenopyrite mineralisation associated with low gold grades, such as 7 metres grading 0.16g/t Au and >0.5% As from 1,176 metres. Footwall to the seismic reflector, the hole intersected the down dip and normal offset extensions to the Western Monzodiorite (MZD) that was also mineralised. In summary, significant gold intercepts from the extension of RWD061 include:

RWD061 8.7 metres grading 1.15g/t Au from 1104.3 metres; incl 3 metres grading 2.78g/t Au from 1110 metres; and 0.3 metres grading 11.4g/t Au from 1208.9 metres (visible Au); and 2 metres grading 5.90g/t Au from 1232 metres (MZD); and 1 metre grading 2.44g/t Au from 1291 metres (MZD).

The reflector where intersected by RWD061 is hosted by metasediments. As observed at the Tomingley deposits, higher gold grades and broader intercepts will likely occur where mineralised structures intersect a favourable rheological and chemical host lithologies such as the andesite or monzodiorite at Roswell. Further drilling is planned in the areas above and below RWD061 to test where the conduit structure intersects the Andesite and the MZD. The flexure in the reflector albeit in the metasediments of the Cotton Formation is also a favourable structural setting and is also planned to be tested.

A significant portion of the Roswell underground Inferred Resources (408 kt grading 1.9 g/t Au - ASX Announcement 15 October 2025 ) is hosted in the Western Monzodiorite domain. A program of intensive underground diamond core drilling targeting the mid-portion of the Western Monzodiorite domain within the Inferred Resources was recently completed. The drilling will improve the confidence of the Mineral Resource Estimation (MRE) and provide a basis for conversion to Ore Reserves.

Results have been received from 21 holes totalling 4,019 metres that are targeting the mid-portion of the monzodiorite domain infilling existing drilling to a nominal 15m x 20m grid spacing for the purpose of converting to an Indicated Resource. The drilling confirmed multiple wide, high-grade gold intercepts within the 30 m thick monzodiorite, particularly along its western margin. Best intercepts include:

ROSUG425D 3.5 metres grading 16.1 g/t Au from 155.8 metres; incl 1.2 metres grading 45.1 g/t Au from 158.1 metres. ROSUG576D 0.6 metres grading 20.7 g/t Au from 128.3 metres; and 12.8 metres grading 1.96 g/t Au from 157 metres; incl 1 metres grading 14.0 g/t Au from 157 metres. ROSUG647D 10.1 metres grading 3.81 g/t Au from 110.6 metres. ROSUG656D 3.6 metres grading 7.31 g/t Au from 187 metres; incl 1 metres grading 24.6 g/t Au from 189.6 metres; and 1.3 metres grading 38.7 g/t Au from 195.6 metres. ROSUG657D 0.5 metres grading 13.5 g/t Au from 151.3 metres; and 3.7 metres grading 3.62 g/t Au from 168.7 metres; and 5.9 metres grading 31.0 g/t Au from 177.9 metres; incl 2.1 metres grading 78.4 g/t Au from 177.9 metres.

El Paso and Regional Exploration

Recent regional exploration to generate new targets for discovery of gold resources outside of the Tomingley Gold Operations has included 3,341 metres of air-core drilling testing areas of covered bedrock, a high-resolution drone magnetic survey, and rock chip sampling of outcropping areas. Assay results were received from target testing exploration comprising of seven mud rotary pre-collared diamond core drill holes at the El Paso prospect and one RC drill hole at the Westray prospect.

At El Paso, a total of 1,964 metres were completed to test the extent of dacite-associated gold mineralisation such as 32.1m at 1.65g/t Au from 66.9m and 6.1m at 3.03g/t from 120.9m ( EPD017 – ASX announcement 14 August 2025 ), according to the interpretation of a moderately SE-dipping sill. When most of the holes failed to intersect the dacite, the interpretation was reviewed with the data from the new drilling and relogging of earlier holes. The new interpretation has three distinct dacite lavas that strike NNE and dip subvertical to the WNW. One drill hole (EPD024) was also planned to test for an offset to the dacite northwest of a significant northwest striking fault. The drilling did not intersect dacite. Whilst the current drilling orientation was not optimal to test this new interpretation and any future drilling will be now collared from the west, significant gold mineralisation was still intercepted including:

EPD020 17 metres grading 4.02 g/t Au from 82 metres; incl 3.8 metres grading 14.1 g/t Au from 89 metres; incl 0.5 metres grading 77.5 g/t Au from 92.3 metres; and 8 metres grading 2.10 g/t Au from 133 metres. EPD021 9.6 metres grading 0.80 g/t Au from 60 metres; incl 1 metres grading 4.41 g/t Au from 64 metres. EPD022 2 metres grading 1.18 g/t Au from 97 metres; and 6 metres grading 0.99 g/t Au from 107 metres.

Previous air-core and soil sampling identified the Westray prospect as a multipoint Au-As target hosted in the prospective Mingelo Volcanics ( ASX announcement 14 August 2025 ). The prospect had not been previously tested by RC or diamond drilling. One RC drill hole was recently completed to 194m to test the shallow gold mineralisation at depth in fresh rock, intersecting significant results of:

WSRC001 1 m grading 2.49 g/t Au from 115 metres; and 6 m grading 0.59 g/t Au from 143 metres.

The drill hole intersected a thick package of volcaniclastic metasediments with one thin andesitic volcanic with diffuse peperitic contacts. Approximately 100m of bleaching sericite alteration with varying levels of quartz veining associated with elevated gold and arsenic was intersected from 95m downhole. Further exploration is to focus on identifying a significantly sized (+30m thick) volcanic host that intersects this mineralised structure.

Further Work

Surface exploration drilling at Tomingley mine site has commenced with diamond core drilling to test the underground potential at the Wyoming Three deposit, and the northern extensions of the main andesite host at Caloma.

The recent significant gold results from the underground drilling of the Western Monzodiorite domain has initiated a second phase of drilling that will test the upper and lower portions of the Inferred domain. This program is underway and expected to be completed by Q3 2026.

Near-mine exploration has recommenced with two diamond core drill holes planned to further characterise the mineralisation identified at the Tomingley One and Tomingley Two prospects. A 1,600m deep diamond core drill hole, to test beneath the Peak Hill epithermal gold deposits for the existence of a Cu-Au porphyry beneath the epithermal gold lithocap.

Planned to commence in Q2 2026 are four diamond core drill holes at Glen Isla to test epithermal gold targets generated from an Induced Polarisation (IP) survey completed in 2025. Additional mud rotary diamond core drilling at El Paso is also planned to confirm the updated geological model and to test for extensions to the known mineralisation to inform the exploration target.

(Criteria in this section apply to all succeeding sections.)

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.
Drilling at Roswell Western MZD Inferred Resources as part of mine development
underground drilling was NQ2. Exploration diamond core drilling was HQ3.
DD sample intervals were defined by site geologists during logging to honour geological
boundaries with whole core sampled on intervals defined by the geologist.
RC and AC samples are collected at one metre intervals via a cyclone on the rig. The
cyclone is cleaned regularly to minimise any contamination

Include reference to measures taken to ensure sample representivity and the
appropriate calibration of any measurement tools or systems used.
Sampling and QAQC procedures are carried out using Alkane protocols as per industry best
practice.

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 (eg
‘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 (eg submarine nodules) may
warrant disclosure of detailed information.
Core was laid out in suitably labelled core trays. A core marker (core block) was placed at
the end of each drilled run (nominally 3m) and labelled with the hole number, down hole
depth, length of drill run. Core was aligned and measured by tape, comparing back to this
down hole depth consistent with industry standards. Half core is sampled with a Corewise
automatic core saw.
RC and AC Drilling – the total sample (~20-30kg) is delivered via cyclone into a large
plastic bag which is retained for future use if required. A sub-sample of approximately 1kg
is spear sampled from each plastic bag and composited to make a 3 metres sample
interval. If strong mineralisation is observed by the site geologist this is sampled as a final
1m interval instead.
Gold was determined by fire assay fusion of a 50g charge with an AAS analytical finish.
A multi-element suite was determined using either aqua regia or a multi-acid digest with a
ICP Atomic Emission Spectrometry or ICP Mass Spectrometry analytical finish..
Drilling
techniques

Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg 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).
Reverse circulation (RC) drilling using 110mm rods 144mm face sampling hammer.
Triple tube diamond drilling with PQ3/HQ3 wireline bit producing 83mm diameter (PQ3) and
61.1mm diameter (HQ3) sized orientated core (using a Reflex orientation tool). In areas of
deep cover, the collars were emplaced using mud rotary through the cover sequence and
not sampled. Underground drilling at Roswell were drilled using NQ2.
Air-core (AC) drilling using 89mm rods and bit to refusal.
Drill sample
recovery

Method of recording and assessing core and chip sample recoveries and results
assessed.
DD - core loss was identified by drillers and calculated by geologists when logging. Core
was only lost in the saprolite for approximately ≥95% recovery in the oxide material.
RC and AC sample quality is assessed by the sampler by visual approximation of sample
recovery and if the sample is dry, damp or wet.

Measures taken to maximise sample recovery and ensure representative nature of the
samples.
Sample quality is qualitatively logged.

A high capacity RC rig was used to enable dry samples collected. Drill cyclone is cleaned
between rod changes and after each hole to minimise cross-hole contamination.
A high capacity AC rig was used to maximise penetration through the clays to refusal on
fresh bedrock. Drill cyclone was cleaned after each hole to minimise cross-hole
contamination.
Triple tube coring is used at all times to maximise core recovery for diamond drilling. All NQ2
core was whole sampled to ensure representativity of sampling.

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.
There is no known relationship between sample recovery and grade.
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.
DD - all core was laid out in core trays and geologically logged for characteristics such as
lithology, weathering, alteration (type, character and intensity), veining (type, character and
intensity) and mineralisation (type, character and volume percentage). A brief geotechnical
log was also undertaken collecting parameters such as core recovery, RQD, fracture count,
and fracture type and orientation.
RC/AC - Each one metre interval is geologically logged for characteristics such as lithology,
weathering, alteration (type, character and intensity), veining (type, character and intensity)
and mineralisation(type,character and volumepercentage).

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc)
photography.
Mostly logging was qualitative with visual estimates of the various characteristics. In
addition, magnetic susceptibility data (quantitative) was collected as an aid for logging.
All drill holes were geologically logged into Geobank Mobile, followed by validation before
importing into Alkane’s central Geobank database.
All drill holes were logged by qualified and experienced geologists.

The total length and percentage of the relevant intersections logged.
All drill holes were logged in full, except for the mud rotary technique through the cover
sequence.
Sub-sampling
techniques and
sample
preparation

If core, whether cut or sawn and whether quarter, half or all core taken.
HQ core sawn with half core samples submitted for analysis. NQ2 core whole sampled and
submitted for analysis.

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or
dry.
Each one metre interval is spear sampled with 3m composite samples collected in a calico
sample bag and forwarded to the laboratory. Where strong mineralisation is observed by
the site geologist, instead of compositing, this is individually sampled from the cone splitter
on the RC rig as a 1 metre interval into a calico bag and forwarded to the laboratory.
Laboratory Preparation – the entire sample (~3kg) is dried and pulverised in an LM5 (or
equivalent) to ≥85% passing 75µm. Bulk rejects for all samples are discarded. A pulp
sample (±100g) is stored for future reference.

For all sample types, the nature, quality and appropriateness of the sample preparation
technique.
Samples were delivered to ALS Minerals Laboratory, Orange NSW. Crushed with 70%
<2mm (ALS code CRU-31), split by riffle splitter (ALS code SPL-21), and pulverised
1000grm to 85% <75um (ALS code PUL-32). Crushers and pulverisers are washed with
QAQC tests undertaken (ALS codes CRU-QC, PUL-QC).

Quality control procedures adopted for all sub-sampling stages to maximise
representivity of samples.
Internal QAQC system in place to determine accuracy and precision of assays.

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.
Entire core sampling was undertaken for NQ2. Non-biased core cutting for HQ using an
orientation line marked on the core.
Duplicate RC and AC samples are collected for both composite intervals and re-split
intervals.

Whether sample sizes are appropriate to the grain size of the material being sampled.
Sample sizes are considered appropriate to the grain size of the material being sampled.
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.
All samples were analysed by ALS Minerals.
Gold is determined using a 50g charge fused at approximately 1100°C with alkaline fluxes,
including lead oxide. The resultant prill is dissolved in aqua regia with gold determined by
flame AAS.
Other geochemical elements, DD core and bottom of hole AC samples are digested by near-
total mixed acid digest with each element determined by ICP Atomic Emission Spectrometry
or ICP Mass Spectrometry. RC and AC samples are digested by aqua regia with a ICP
Atomic Emission Spectrometry for As, Cu, Fe, Ni, P, Pb only.

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.
Underground drill holes were laid out by underground survey. Surface drillholes are laid out
using hand-held GPS (accuracy ±2m) then all RC and DD collars are DGPS surveyed
accurately (± 0.1m) by trained surveyors on completion.
Drill holes were surveyed during drilling to maintain drilling direction. Diamond drill holes are
multi-shot at 6m intervals on retrieval of rod string using a multi shot electronic camera.

Specification of the grid system used.
GDA94, MGA (Zone 55).

Quality and adequacy of topographic control.
The area is very flat. A site based digital terrain model was developed from accurate (±
0.1m) survey control by licenced surveyors.Topographic control is considered adequate.
Data spacing
and distribution

Data spacing for reporting of Exploration Results.
Infill drilling at the Roswell Western MZD is completed on a pattern of 10m x 15m pattern.
At the other targets, the exploration stage is early and data spacing is variable with the
focus on identifying new zones of mineralisation.

Whether the data spacing and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications applied.
The mineralisation domains tested by this drilling is classified as Inferred based on its data
distribution and hosted in the same monzodiorite domain. All the new drilling intersected
the monzodiorite host and their spacing and distribution will be sufficient to further inform
this Inferred resource mineralisation domain.
All the other results are early stage, reconnaissance drilling, and as such are spaced to test
strike and dip extents of any significant mineralisation.

Whether sample compositing has been applied.
DD – diamond core interval samples are based on geological logging, and are simple
intervals as described earlier in the table.
RC – samples with no visible mineralisation or alteration are composited to 3m with 1m
resamples assayed if the composite returned a gold value of >0.2g/t gold. One metre
samples override 3m composites in the database.
Orientation of
data in relation
to geological
structure

Whether the orientation of sampling achieves unbiased sampling of possible structures
and the extent to which this is known, considering the deposit type.
At Roswell, much care was given to attempt to intersect mineralisation at an optimal angle
but location of drill drives is the major determination of intersection angle. Most holes are 80% of
true thickness.
At other targets, drilling suggests a broadly sub vertical geometry at most prospects.

If the relationship between the drilling orientation and the orientation of key mineralised
structures is considered to have introduced a sampling bias, this should be assessed
and reported if material.
It is not thought that drilling direction will bias assay data.
Sample
security

The measures taken to ensure sample security.
All samples were bagged in tied numbered calico bags, grouped into larger tied polyweave
bags and transported to the laboratory in Orange by courier. S ample submission sheets
were delivered with the samples and also emailed to the laboratory. All sample
submissions were documented via ALS tracking system and all assays were reported via
email.
Sample pulps were returned to site and were stored for an appropriate length of time
(minimum 3 years).
The Company has in place protocols to ensure data security.

Geology
Deposit type, geological setting and style of mineralisation.
Mineralisation is associated with quartz veining and alteration focused within sub-volcanic
basaltic-andesite sills and adjacent volcaniclastic sediments. The deposits appear to have
formed as the result of a rheological contrast between the porphyritic sub-volcanic sills and
the surrounding volcaniclastic sediments, with the sills showing brittle fracture and the
sediments ductile deformation and have many similarities to well documented orogenic -
lode-style gold deposits.
Geological nature of the Tomingley and Peak Hill Deposits are well documented elsewhere.
Drill hole
Information

A summary of all information material to the understanding of the exploration results
including a tabulation of the following information for all Material drill holes:
o
easting and northing of the drill hole collar
o
elevation or RL (Reduced Level – elevation above sea level in metres) of the drill
hole collar
o
dip and azimuth of the hole
o
down hole length and interception depth
o
hole length.
See body of announcement.

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.
All RC and DD drill holes have been reported in this announcement.

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.
Exploration results reported for uncut gold grades, grades calculated by length weighted
average.

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.
Reported intercepts for exploration drilling are calculated using a broad lower cut of 0.2g/t
Au and for Underground Resource drilling at Roswell using a broad lower cut of 1.0g/t Au.
Although grades lower than these may be present internally (internal dilution).
Short intervals of high grades that have a material impact on overall intersection are
reported as separate (included) intervals.

The assumptions used for any reporting of metal equivalent values should be clearly
stated.
No metal equivalents are reported.
Relationship
between
mineralisation
widths and
intercept
lengths

These relationships are particularly important in the reporting of Exploration Results.
o
If the geometry of the mineralisation with respect to the drill hole angle is known, its
nature should be reported.
o
If it is not known and only the down hole lengths are reported, there should be a
clear statement to this effect (eg ‘down hole length, true width not known’).
Reported results include the drilled width and an estimate of true width.
At Roswell the true width is approximately 80% of the drilled width. The majority of the
exploration drilling is reconnaissance in nature. Down hole lengths are reported – true
widths estimated to be 50% of the down hole lengths at El Paso and unknown at the other
prospects at this early stage exploration stage.
Diagrams
Appropriate maps and sections (with scales) and tabulations of intercepts should be
included for any significant discovery being reported These should include, but not be
limited to a plan view of drill hole collar locations and appropriate sectional views.
Cross sections and plans showing drilling with 3D geological modelling are included in the
body of this announcement for data rich areas. Plans showing geology with drill collars with an
appropriate sectional view for the significant results at El Paso prospect are also included.
Balanced
reporting

Where comprehensive reporting of all Exploration Results is not practicable,
representative reporting of both low and high grades and/or widths should be practiced
to avoid misleading reporting of Exploration Results.
Comprehensive reporting has been undertaken with all drill holes listed in the included table.
Other
substantive
exploration
data

Other exploration data, if meaningful and material, should be reported including (but
not limited to): geological observations; geophysical survey results; geochemical survey
results; bulk samples – size and method of treatment; metallurgical test results; bulk
density, groundwater, geotechnical and rock characteristics; potential deleterious or
contaminating substances.
No other exploration data is considered meaningful for reporting.
Further work
The nature and scale of planned further work (eg tests for lateral extensions or depth
extensions or large-scale step-out drilling).
See body of announcement. Further underground drilling will be undertaken to improve
resource classification from Inferred to Indicated at Roswell.

Diagrams clearly highlighting the areas of possible extensions, including the main
geological interpretations and future drilling areas, provided this information is not
commercially sensitive.
See figures included in the announcement.
