High-Grade Drilling Results of up to 11m @ 6.0g/t Au at Julias to Underpin Impending Resource Estimate

In-fill drilling confirms consistent zone of shallow high-grade oxide mineralisation

HIGHLIGHTS

  • Extensive high-grade assay results received from recently completed in-fill Reverse Circulation drilling program completed over the Julias deposit:

  • GRC796: 11m @ 6.0g/t Au from 58m

  • GRC781: 4m @ 6.1g/t Au from 30mGRC811: 8m @ 3.2g/t Au from 60mGRC845: 4m @ 4.0g/t Au from 57mGRC797: 13m @ 2.6g/t Au from 71mGRC804: 10m @ 2.7g/t Au from 52mGRC812: 11m @ 2.2g/t Au from 43mGRC789: 5m @ 2.6g/t Au from 55mGRC791: 6m @ 2.8g/t Au from 72mGRC795: 7m @ 2.8g/t Au from 36mGRC801: 7m @ 2.5g/t Au from 51m

  • Results have confirmed the continuity of the high-grade oxide zone over a strike length of 500m.

  • Results to be compiled to include in the maiden Mineral Resource Estimate for Julias, expected to be completed later this quarter.

  • Previously announced air-core results confirm the continuation of this mineralisation for a further 700m to the south-west, indicating the clear potential to expand with further RC drilling.

Gateway’s Managing Director, Mr Mark Cossom, said: “The Julias oxide deposit has rapidly emerged as one of the most exciting new discoveries at the Gidgee Gold Project. The recent in-fill RC program has well and truly lived up to expectations, delivering consistent high-grade results across the currently defined 500m strike length of the deposit.

“The oxide mineralisation has been clearly defined and we now have sufficient data to commence work on a Mineral Resource Estimate, which we are aiming to complete later this quarter and add to our overall Gidgee Resource inventory. Importantly, we believe that this will represent just the first step at Julias, as the oxide zone has been traced for a further 700m to the south-west.

“Detailed RC drilling is required over this extension before we can advance it to resource status, and we intend to progress this work as a priority over the rest of this year. The drilling completed at Julias has established this deposit as having potential to make a material contribution to our resource inventory at Gidgee, and we are looking forward to completing the work to make this happen.”

Gateway Mining Limited (ASX: GML) ( Gateway or Company ) is pleased to report outstanding new high-grade assay results from in-fill Reverse Circulation ( RC ) drilling completed at its emerging Julias oxide gold deposit, within the 449,000oz[1] Gidgee Gold Project in the Murchison Region of Western Australia.

RC drilling was carried out to provide regular data coverage across the 500m of strike length at the main Julias oxide zone. A total of 46 holes for 4,203m of RC drilling were completed over the Julias discovery, primarily targeting oxide mineralisation within the top 70m. Holes were designed to in-fill existing RC drilling to a nominal 25m x 25m drill pattern (Figure 2) (see Table 1 and Appendix A for detail).

Consistent high-grade oxide mineralisation was returned from throughout the 500m of strike covered by drilling (Figure 2), largely within 70m of surface:

  • GRC796: 11m @ 6.0g/t Au from 58m

  • GRC781: 4m @ 6.1g/t Au from 30mGRC811: 8m @ 3.2g/t Au from 60mGRC845: 4m @ 4.0g/t Au from 57mGRC798: 4m @ 3.1g/t Au from 51mGRC797: 13m @ 2.6g/t Au from 71mGRC804: 10m @ 2.7g/t Au from 52m (Hole abandoned in mineralisation) ▪ GRC812: 11m @ 2.2g/t Au from 43mGRC789: 5m @ 2.6g/t Au from 55mGRC791: 6m @ 2.8g/t Au from 72mGRC795: 7m @ 2.8g/t Au from 36mGRC801: 7m @ 2.5g/t Au from 51mGRC794: 4m @ 2.0g/t Au from 56mGRC846: 22m @ 1.7g/t Au from 62mGRC799: 10m @ 1.8g/t Au from 72mGRC809: 4m @ 2.4g/t Au from 27mGRC872: 3m @ 4.2g/t Au from 70m, and 9m @ 1.7g/t Au from 81m

  • GRC802: 17m @ 1.0g/t Au from 99m

At Julias, high-grade supergene mineralisation is contained in a heavily weathered sedimentary and felsic volcanic rock sequence, associated with a moderately west dipping gossanous quartz-breccia fault zone. The high-grade mineralisation is present at shallow depths, as shown in the schematic cross-section Figure 3.

The oxide mineralisation is geometrically consistent and can be traced through the entire 500m of strike. Within the fresh rock, this fault zone presents as massive sulphide with quartz veining, however, grade tenor is reduced and has not been pursued with this RC drill program.

Importantly, shallow intersections returned in holes GRC781 (4m @ 6.1g/t Au from 30m), GRC795 (7m @ 2.8g/t Au from 36m) and GRC809 (4m @ 2.4g/t Au from 27m) are completely open up-dip and represent prime targets for future RC drilling to establish a zone of mineralisation immediately below surface.

All results will be compiled in order to complete a maiden Mineral Resource Estimate for Julias.

In addition, previously announced air-core drilling[2] demonstrated the continuation of this mineralised zone for a further 700m along strike to the south-west, towards the Flametree target area (see Figure 4), with an extensive zone of shallow, oxide-zone intercepts. This south-western extension is yet to be tested by RC drilling, and remains a target for future work.

Ongoing Exploration Activities

Despite industry-wide delays in assay turnaround times, Gateway has continued to pursue its strategy of exploring for additional mineralisation within 5km of its existing 449,000oz Mineral Resources. In line with this, RC drilling has continued on-site. A further 15,000m of RC is planned, primarily targeting extensions to existing Resources at Evermore, Montague-Boulder and Achilles, as well as beneath the historic Caledonian open pit and systematic testing of the eastern margin of the Montague Granodiorite for the first time. This program is currently approximately 60% complete.

Following completion of the RC program, preparations are underway to undertake a regional air-core program of approximately 16,000m, testing high-priority regional targets from throughout the Gidgee Gold Project. It is anticipated that this targeting will provide additional targets for follow-up drilling in 2023.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (e.g. 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 pulverized 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.

RC drilling (GRC prefix) - 2kg - 3kg samples were split from dry 1m bulk
samples. The sample was initially collected from the cyclone in an inline
collection box. Once the metre was completed the sample was dropped under
gravity thorough a cone splitter, with the 1m split for assay collected in a calico
bag.

The bulk reject from the sample was collected in buckets and dumped into neat
piles on the ground.

RC Field duplicates were collected at a ratio of 1:50 and collected at the same
time as the original sample through the B chute of the cone splitter. OREAS
certified reference material (CRM) was inserted at a ratio of 1:50. The grade
ranges of the CRM’s were selected based on grade populations and economic
grade ranges.
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.).

RC – Challenge Drilling drill rig was used. The rig consisted of a truck mounted
RC rig with on board compressor, an on board Booster, and a truck mounted
auxiliary compressor.
Drill
sample
recovery

Method of recording and assessing core and chip sample recoveries and
results assessed.

Measures taken to maximize 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.

During the RC sample collection process, the sample sizes were visually
inspected to assess drill recoveries.

The majority of samples were of good quality with ground water having minimal
effect on sample quality or recovery.

From the collection of recovery data, no identifiable bias exists.
Logging

length of each hole. Chips were visually inspected and logged to record
lithology, weathering, alteration, mineralisation, veining and structure.

Data on rock type, deformation, colour, structure, alteration, veining,
mineralisation and oxidation state were recorded.

Logging is both qualitative and quantitative or semi quantitative in nature.
Sub-sampling
Techniques
and
sample
preparation

If core, whether cut or sawn and whether quarter, half or all core taken.

If non-core, whether riffled, tube sampled, rotary split, etc. and whether
sampled wet or dry.

For all sample types, the nature, quality and appropriateness of the sample
preparation technique.

Quality control procedures adopted for all sub-sampling stages to maximise
representivity of samples.

Measures taken to ensure that the sampling is representative of the in situ
material collected, including for instance results for field duplicate/second-half
sampling.

Whether sample sizes are appropriate to the grain size of the material being
sampled.

RC Samples were split from dry, 1m bulk sample via a cone splitter directly
from the cyclone.

The QC procedure adopted through the process includes:

Field duplicates were collected at a rate of 1:50, these were collected
during RC drilling at the same time as the primary sample.

OREAS certified material (CRM) was inserted at a rate of 1:50, the grade
ranges of the CRM’s were selected based on grade populations.

0.8-3kgs of sample was submitted to the laboratory.

Samples oven dried then pulverized in LM5 mills to 85% passing
75micron.

All samples were analysed for Au using the Au-AA26 technique which is
a 50g lead collection fire assay.
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 (e.g. standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been established.

Drill samples were submitted to ALS (Perth). All samples were analysed by a
50g fire assay (AAS finish) which is a total digest assay technique.

RC Field duplicates were collected at a rate of 1:50 with CRM’s inserted at a
rate of 1:50 also. The grade ranges of the CRM’s were selected based on grade
populations.
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

Drilling results are cross checked by company geologists.

Data is recorded digitally at the project within MicroMine Geobank software,
assay results are received digitally.

All data is stored within DataShed SQL Database.
Criteria JORC Code explanation Commentary
storage (physical and electronic) protocols.

Discuss any adjustment to assay data.
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.

Initial drill hole location is initially recorded with a handheld Garmin GPS (+/-
3m). A Reflex EZ North Seeking Gyro is used to record the deviation of the drill
holes (+/- 1deg). All collars were surveyed post-drilling utilising RTK-GPS.
Data spacing
and
distribution

Data spacing for reporting of Exploration Results.

Whether the data spacing and distribution is sufficient to establish the degree
of geological and grade continuity appropriate for the Mineral Resource and
Ore Reserve estimation procedure(s) and classifications applied.

Whether sample compositing has been applied.

RC holes have been completed on a nominal 25 x 25m pattern over the main
Julias deposit.

Holes drilled within this program are considered to be of suitable data spacing
for use in a Resource estimation.
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.

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.

The drilling was orientated perpendicular to the perceived strike of the
mineralised structures, with holes drilled to the east. Inclined holes (-60°) are
considered to be appropriate to the dip of the mineralised structure creating
minimal sampling bias.
Sample
security

The measures taken to ensure sample security.

Calico samples are sealed into green/poly weave bags and cable tied. These
are then sealed in bulka bags and transported to the laboratory in Perth by
company staff or contractors or established freight companies.
Audits
or
reviews

The results of any audits or reviews of sampling techniques and data.

Drilling results are cross checked by company geologists.

Gold was discovered in the district during the gold rush era, first records of
gold won from small-scale, high-grade workings include the Montague Mining
Centre (1904-13). Renewed interest in the late 1960's included base metal
exploration carried out within exposed stratigraphy of the Montague Ranges
(Bungarra Ranges), exploration interest that broadened with the release of the
Sandstone 1:250,000 aeromagnetic sheet in 1970 resulting in the staking of
favourable magnetic anomalies by exploration companies.

Early explorers in the Montague Ranges included Anaconda Australia Inc.
(1966-67), followed by International Nickel Australia (1971-75) evaluating a
Gabbro - banded differentiated basic complex believed prospective for copper
and/or nickel such as the Dulith Gabbro, USA. Strong geophysical and
mineralised anomalism was encountered, however, copper-zinc enrichment
was also encountered in adjacent felsic stratigraphy at Ed's Bore prospect,
which was followed-up by CRA Exploration (1983-1990) to intersect
polymetallic VMS enrichments at Bevan prospect (not substantively pursued).

At Montague, Western Mining Corporation (1976) conducted investigations for
copper and gold including soil sampling and IP surveying, which was followed
by CRA Exploration (1984-89) working concurrently with AMOCO Minerals
Australia Company (1984) and Clackline Refractories Ltd (from 1985 - to later
become Herald Resources) assessing/purchasing historic mine areas from Mr
W.J. Griffiths of Sandstone. RAB drilling penetrating transported cover resulted
in the virgin discoveries of NE Pit by AMOCO and Whistler deposit by CRA.
Later noted explorers included Dalrymple Resources NL (1987-1990)
intersecting gold at the Armada (Twister) prospect, and Arimco Mining (1990-
98) intersecting gold at Lyle prospect, Victory West prospect, and copper at
The Cup prospect (not substantively pursued).

The Montague Mining Centre produced approximately 150,000oz of gold
commencing in 1986 at Caledonian and NE Pits (Clackline), and continued at
MontagueBoulder from 1988 (Herald), andwas to closein 1993 after

completion of the Rosie Castle open cut (Herald). Whistler open cut was mined
from November 1990 (Polaris Pacific NL) and ore toll treated through the
Herald mill. Little attention was paid to mineralisation other than gold. Gateway
Mining in joint venture with Herald Resources continued exploration of the
Montague Mining Centre, Gateway also targeting poly-metallic intrusion
related - VMS models in the district from 2006.

Airport, Airport Sth, S Bend, Rosie Nth, Rosie Sth mineralisation was
discovered by Gateway Mining between 2007 and 2011 in RAB drilling and
later defined by RC drilling.
Geology
Deposit type, geological setting and style of mineralisation.

Gateway’s Gidgee Project is located in the Gidgee district in the Archean
Yilgarn Craton of Western Australia approximately 630km NE of Perth and
70km north from the township of Sandstone on the eastern central portion of
the Gum Creek Greenstone Belt, of the Southern Cross Province.
Metamorphic grade of the Gum Creek Greenstone Belt is estimated to be low-
grade greenschist facies.

Project lithology includes basalt/ash tuff/dolerite/gabbro, the Montague
Granodiorite sub-volcanic intrusion (calc-alkaline - FI), dacite volcanic flow/s
(FI), volcaniclastic sequences of felsic composition and epiclastic
conglomerates, ultramafic intrusives and external orogenic granite plutons.
Key regional characteristics of a Volcanic Arc Extensional Basin include calc-
alkaline bimodal volcanic sequences associated with extensive iron
formations. Later ENE-WSW orogenic compression event is characterised by
NNW regional scale faults/unconformities, NNW shearing and folding, slaty
cleavage has developed within sediments near a tight syncline fold closure
within the NE area of the project.

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

Exploration drill results from recent drilling, and associated details are
contained in Table 1 of this release.

o hole length.

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. _
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.

Significant intersections are calculated based on a lower cut-off of minimum
1m @ 0.8g/t Au, with a maximum of 4m internal dilution. This is considered
appropriate for the intended use of the data for tracing Au within the oxide
zone.

No high-grade cut-off has been applied
Relationship
between
mineralisation
widths
and
intercept
lengths

These relationships are particularly important in the reporting of Exploration
Results.

If the geometry of the mineralisation with respect to the drill hole angle is
known, its nature should be reported.

If it is not known and only the down hole lengths are reported, there should be
_a clear statement to this effect (eg ‘down hole length, true width not known’). _

The drill holes were orientated as inclined holes (-60°), toward 090°, as this is
considered to be appropriate for the interpreted dip of the major mineralised
structure – parallel to the Montague-Boulder shear zone - creating minimal
sampling bias.
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.

Appropriate maps are included in the announcement
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.

The accompanying document is considered to be a balanced report with a
suitable cautionary note.
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. _

The area has been covered by detailed ground gravity and airborne magnetic
surveys. Previous drilling is limited to set depth RAB which is considered to
have been an ineffective test, some 50m x 25m spaced AC and RC exists in
the North east part of the prospect.
Further work
The nature and scale of planned further work (eg tests for lateral extensions
or depth extensions or large-scale step-out drilling).

Additional air-core and RC drilling will be undertaken to continue tracing the
anomalous mineralised structure along strike.
