MULTIPLE HIGH-GRADE GOLD INTERCEPTS FOR RESOLUTION AND ADVENTURE PROSPECTS

RESULTS PAVE WAY FOR MAIDEN MINERAL RESOURCE AT STAWELL CORRIDOR GOLD PROJECT

  • New diamond core drilling results at the Resolution and Adventure prospects confirm further multiple zones of high-grade gold mineralisation, with assays of up to 55.7 grams per tonne gold. Best results include:

Resolution:

  • 0.5 metres @ 55.7 g/t Au from 508.9m in RD033

  • 4.0 metres @ 3.1 g/t Au from 558.8m in RD040

  • 3.1 metres @ 3.1 g/t Au from 331.3m, including 0.7 metres @ 11.2 g/t Au in RD035

Adventure:

  • 3.2 metres @ 9.6 g/t Au from 263.6m, including 0.9 metres @ 12.5 g/t Au in AD007

  • 8.4 metres @ 3.4 g/t Au from 405.6m, including 0.9 metres @ 13.7 g/t Au in AD008

  • At Resolution, a 12,000 metre resource definition drilling program is now complete, paving the way for the first instalment of a significant mineral resource by the end of this month.

  • A further program of diamond core drilling has commenced at Resolution to test beyond the extents of the anticipated resource.

  • The diamond core program at the Adventure prospect records its best gold hits and first visible gold, with a further 2,000m diamond program to start shortly.

  • Both prospects are part of the Company’s flagship Stawell Corridor Gold Project, which bears similar gold mineralisation to the nearby multi-million ounce Magdala gold deposit.

Navarre Minerals Limited (ASX: NML) (Navarre or the Company) reports further high-grade gold assay results from diamond core drilling recently completed on its 100 per cent owned Stawell Corridor Gold Project, 20 kilometres south of Stawell’s five million ounce Magdala Gold Mine in Victoria (Figure 1).

The latest drill results relate to the Resolution and Adventure prospects on the eastern flank of the Irvine basalt dome which has been subject to extensive 12,000 metre and 2,000 metre diamond drilling campaigns respectively (Figures 2 & 3).

Revealing grades of up to 55 grams per tonne, the results confirm the strike length of gold mineralisation at Resolution’s South Shoot (the bigger of Resolution’s two lode channels) to be approximately 1.3 kilometres, extending from surface to beyond 400 metres depth, remaining open down-plunge (see Figure 2).

In all, the resource definition program at Resolution comprised 27 diamond holes, drilled on a nominal 80 x 80 metre grid pattern. This release covers the results for the last nine diamond holes of the program. Earlier results for the program were announced to the ASX on 27 April 2020, 8 July 2020, 25 September 2020 and 23 December 2020.

The latest results come from testing the basal areas of the South Shoot where drilling focussed on defining a potential economic boundary to the gold mineralisation. Significant results include (See Tables 1 & 2; Figure 2):

  • 0.5 metres @ 55.7 g/t Au from 508.9 metres in hole RD033

  • 4.0 metres @ 3.1 g/t Au from 558.8m in RD040

  • 3.1 metres @ 3.1 g/t Au from 331.3m, including 0.7 metres @ 11.2 g/t Au in RD035

An additional hole, RD041 was drilled to the east of the main mineralised zones to test the stratigraphy and for potential new zones of gold mineralisation. Assays for this hole are pending at the time of this release.

The drilling continues to expand the extents of a strongly mineralised quartz-rich shear structure (referred to as the Main Zone) that continues from surface and extends beyond 400 metres depth, remaining open down-plunge to the south.

The recent assays also show evidence of multiple high-grade mineralised structures and associated quartz veining on both the western (hangingwall) and eastern (footwall) sides of the Main Zone (see Table 2).

At Adventure, the 2,000 metre expansion diamond core drilling program has also delivered on its aim of testing the gold-bearing quartz-sulphide shear structure at depth, producing the prospect’s best gold intercepts to date.

With assays available for three out of the four holes drilled, the better results at Adventure include (See Tables 1 & 3; Figure 3):

  • 3.2 metres @ 9.6 g/t Au from 263.6 metres, including 0.9 metres @ 12.5 g/t Au in AD007

  • 8.4 metres @ 3.4 g/t Au from 405.6m, including 0.9 metres @ 13.7 g/t Au in AD008

The mineralised structure remains open at depth and along strike and the Company is now preparing to expand the drill testing with a further 2,000 metre diamond core program. This drilling is expected to commence in April 2021, upon receipt of final approvals.

The diamond drilling at Resolution and Adventure is expected to underpin the first instalment of a mineral resource and exploration target for the Stawell Corridor Gold Project, which currently remains on-track for announcement by the end of this month.

At present, one diamond drilling rig continues to operate at Resolution testing beyond the extents of the anticipated resource.

Across the entire resource definition drilling program at Resolution, the best results returned from the Main Zone include: 5 metres @ 10.0 g/t Au, 9.4 metres @ 5.3 g/t Au and 7.7 metres @ 5.6 g/t Au; and from the Hangingwall Zones: 10.8 metres @ 4.5 g/t Au, 0.6 metres @ 55 g/t Au and 1.0 metre @ 20.8 g/t Au.

Navarre Managing Director Ian Holland said:

“Our recently completed resource definition diamond core drilling program at the Resolution prospect continues to deliver multiple strong intersections of gold mineralisation from within a well-defined lode channel.

Several parallel zones of high-grade gold mineralisation to the east and west of the Main Zone are providing further confidence that Resolution has the potential to grow into a large deposit like the nearby Magdala system.

“We remain highly confident on delivering our maiden mineral resource by the end of this month, the first instalment of a growing resource base for our 100% owned Stawell Corridor Gold Project.”

The Company is planning to continue diamond drilling beyond the mineral resource estimation period, with a focus on expanding the potential resource base with infill and step-out drilling on both the Resolution and Adventure prospects .

NEW DRILLING RESULTS IN DETAIL

Resolution prospect

Navarre has completed a 12,000 metre resource definition diamond core drilling program to scope the depth and strike potential of the Resolution prospect discovery and is in the final stages of delivering a maiden mineral resource by the end of March 2021.

A total of 42 diamond core holes have been completed at Resolution since discovery (Figure 4). The recently completed resource definition drilling program has tested the continuity and extent of the Resolution gold discovery by scoping the dimensions of the gold mineralisation using a nominal 80 metre (North-South) by 80 metre (vertical) step-out drill pattern.

Highlight new results (not true widths) at Resolution include (see Tables 1 & 2 and Figure 3):

  • 0.5 metres @ 55.7 g/t Au from 508.9m in RD033

  • 4.0 metres @ 3.1 g/t Au from 558.8m in RD040

  • 3.1 metres @ 3.1 g/t Au from 331.3m, including 0.7 metres @ 11.2 g/t Au in RD035

  • 0.6 metres @ 55.0 g/t Au from 494.1m in drill hole RD032

  • 7.9 metres @ 4.3 g/t Au from 441.4m, including 1.0 metres @ 11.7 g/t Au in drill hole RD032

  • 3.7 metres @ 3.8 g/t Au from 381.3m and 4.0 metres @ 2.1 g/t Au from 370.5m in drill hole RD030

Note: all drill intercepts are reported as down-hole intervals.

The mineralisation is characterised by significant quartz veining (or quartz tension vein arrays), occurring with strong chlorite alteration containing minor amounts of sulphides (typically less than 3 per cent), including arsenopyrite + pyrite + pyrrhotite and rare visible gold. Zones of anomalous gold are typically elevated in arsenic, an important pathfinder metal in most Victorian gold deposits.

The higher-grade gold mineralisation has been interpreted to occur within two lode channels or shoots (referred to as the North and South Shoots) that plunge moderately towards the south and remain open down-plunge (see Figure 4). The South Shoot, with more drill information, has approximate dimensions of up to 400 metres in height, 1,300 metres of strike (open down-plunge to the south) and between 1.5 metres and 6 metres in width.

In summary, interpretation of the diamond results for the South Shoot of the Resolution prospect indicates:

  • gold mineralisation occurs in several sub-parallel, higher-grade structures referred to as the Main, Footwall and Hangingwall zones;

  • gold tenor is relatively uniform, typically ranging between 3 g/t and 10 g/t below the base of oxidation;

  • the estimated true width of gold mineralisation generally ranges between 1 metre and 6 metres; and

  • the estimated strike extent of high-grade gold mineralisation is approximately 1,300 metres and remains open.

Adventure prospect

Navarre has completed a 2,000 metre expansion diamond core drilling program to scope the depth potential of the Adventure prospect with four targeted drill holes (AD006 – AD009) (see Figure 3).

Results for the first three diamond core holes (AD006 – AD008) have been received and have delivered two of the highest grade intercepts recorded to date from a strongly mineralised quartz-sulphide lode structure similar in character to the Main Lode at the Resolution prospect.

AD008 also recorded the first observed speck of visible gold at the prospect in one of the deepest holes, suggesting a potential increase in gold tenor with depth.

Significant new assays results from the Adventure drilling (not true widths) include (see Tables 1 & 3; Figure 3):

  • 3.2 metres @ 9.6 g/t Au from 263.6m, including 0.9 metres @ 12.5 g/t Au in AD007

  • 8.4 metres @ 3.4 g/t Au from 405.6m, including 0.9 metres @ 13.7 g/t Au in AD008

  • 1.0 metre @ 1.8 g/t Au from 254.4m in AD006

These intercepts complement previously reported drill intercepts from Adventure Lode (see ASX announcements 13 Dec 2017, 29 Jan 2019 & 20 Dec 2019):

  • 6.0 metres @ 4.2 g/t Au from 67m, including 4 metres @ 6.1 g/t Au in IRC013

  • 5.0 metres @ 4.0 g/t Au from 41m in IRC004

  • 3.0 metres @ 5.2 g/t Au from 85m in IRC011

  • 4.0 metres @ 3.7 g/t Au from 96m in IRC014

  • 4.0 metres @ 3.6 g/t Au from 14m in IRC015

  • 6.0 metres @ 5.1 g/t Au from 24m in IAC245 (air-core discovery hole)

  • 4.75 metres @ 3.5 g/t Au from 206.9m, including 1.15 metres @ 9.8g/t Au in AD001

  • 4.6 metres @ 3.5 g/t Au from 327.3m downhole in AD002

NEXT STEPS

Navarre plans to finalise the geological and structural models in preparation for resource estimation, in view of announcing the Stawell Corridor Gold Project’s maiden mineral resource by the end of March 2021.

Pending the receipts of requisite approvals, the Company will commence an additional 2,000 metre diamond core drilling program at the Adventure prospect.

STAWELL GOLD CORRIDOR BACKGROUND

The Company is searching for large gold deposits in an extension of a corridor of rocks that host the five million ounce Stawell and one million ounce Ararat goldfields – “The Stawell Gold Corridor” (Figure 1).

A key feature of major gold deposits along the Corridor is that they are hosted in meta-sediments on the margins of Cambrian basalt domes. The five million ounce Magdala gold deposit at Stawell is the best example of this style of mineralisation.

Navarre has identified seven basalt dome structures within the Company’s 70 kilometre long tenement package to date. The Company believes the regional potential of the Stawell Gold Corridor is significant, as shown by Navarre’s discoveries at the Irvine and Langi Logan prospects where gold is close to large basalt dome structures.

The Irvine basalt dome is Navarre’s most advanced prospect. Previous drilling has confirmed extensive shallow gold footprints at the Resolution and Adventure lodes, with a combined strike length of 2.9 kilometres along the eastern contact of the Irvine basalt dome. Navarre has been testing the depth extents of the gold shoots at both lodes down to approximately 400 metres below surface through targeted diamond drilling programs.

The Langi Logan basalt dome is the next major prospect for Magdala-style mineralisation south of the Irvine basalt dome within the Stawell Corridor Gold Project (Figure 1). It consists of the Langi Logan North, Langi Logan Central and the Langi Logan South Cambrian basalt domes with a combined 14.5 kilometre strike length and occurs in an area of significant historical deep lead production (133,000 ounces of gold recorded). Approximately 70 per cent of the prospect area is covered by postmineralisation Newer Volcanics ranging up to 30 metres in thickness.

ABOUT NAVARRE MINERALS LIMITED:

Navarre Minerals Limited (ASX: NML) is an Australian-based gold exploration company focused on discovering large, long-life and high-grade gold deposits in under-explored areas of Victoria’s premier gold districts.

Navarre is searching for gold deposits in an extension of a corridor of rocks that host the Stawell (~five million ounce) and Ararat (~one million ounce) goldfields (The Stawell Corridor Gold Project). The discovery of outcropping gold on the margins of the Irvine basalt dome and high-grade gold in shallow drilling at Langi Logan are a prime focus for the Company. These projects are located 20km and 40km respectively south of the operating 4Moz Stawell Gold Mine.

ASX Announcement

The high-grade Tandarra Gold Projectis located 50km northwest of Kirkland Lake Gold’s world-class Fosterville Gold Mine, and 40km north of the 22 million-ounce Bendigo Goldfield. Exploration at Tandarra, in Joint Venture with Catalyst Metals Limited (Navarre 49%), is targeting the next generation of gold deposits under shallow cover in the region.

The Company is searching for high-grade gold at its St Arnaud Gold Project . Recent reconnaissance drilling has identified gold mineralisation under shallow cover, up to 5km north from the nearest historical mine workings, which the Company believes may be an extension of the 0.4Moz St Arnaud Goldfield.

The Company is also targeting volcanic massive sulphide, epithermal and porphyry copper-gold deposits in the Stavely Arc volcanics. The Project area captures multiple polymetallic targets in three project areas including Glenlyle, Eclipse and Stavely. All properties are currently 100% owned apart from Stavely (EL 5425) which is subject to a farm-in agreement where Stavely Minerals Limited may earn an 80% interest by spending $0.45M over 5 years.

At the Jubilee Gold Project, 25km southwest of LionGold’s Ballarat Gold Mine, the Company is undertaking a systematic exploration program targeting extensions and repetitions of historically mined transverse quartz reefs that bear similarity to the high-grade Swan – Eagle system at Fosterville.

Section 1 Sampling Techniques and Data

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 pulverised to produce a 30g
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.

The diamond drill core samples were selected on
geological intervals varying from 0.2m to 1.6m in length.

All drill core was routinely cut in half (usually on the
right of the marked orientation line) with a diamond saw
and submitted for analysis.

Sample representivity was ensured by a combination of
Company procedures regarding quality control (QC) and
quality assurance/ Testing (QA). Certified standards and
blanks were routinely inserted into assay batches.
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).

Pre-collars were drilled to solid bedrock using an HWT
(114.3mm) drill bit followed by diamond coring with a
diameter of 63.5mm (HQ) and 50.6mm (NQ2).

Diamond drilling of HQ3 (triple-tube) was undertaken to
ensure maximum core recovery.

All drill core was orientated with a Reflex ACT III core
orientation tool then continuously marked with a line
while on an angle iron cradle.
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

All diamond core was logged capturing any core loss, if
present, and recorded in the database.

All drill depths are checked against the depth provided
on the core blocks and rod counts are routinely carried
out by the driller.

Core recovery for the areas sampled was generally
good.

of detail to support appropriate Mineral Resource
estimation, mining studies and metallurgical
studies.

Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)

The total length and percentage of the relevant
intersections logged.

Geological logging of samples followed Company and
industry common practice. Qualitative logging of
samples included (but was not limited to); lithology,
mineralogy, alteration, veining and weathering.

All logging is quantitative, based on visual field
estimates.

Detailed diamond core logging, with digital capture, was
conducted for 100% of the core by Navarre’s geological
team.
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.

Detailed diamond core logging, with digital capture, was
conducted for 100% of the core by Navarre’s geological
team.

Half core was sampled from NQ and HQ diameter drill
core.

Company procedures were followed to ensure sub-
sampling adequacy and consistency. These included
(but were not limited to), daily workplace inspections of
sampling equipment and practices.

Blanks and certified reference materials are submitted
with the samples to the laboratory as part of the quality
control procedures.

No second-half sampling has been conducted at this
stage.

The sample sizes are appropriate to correctly represent
the sought after mineralisation.
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.

Analysis for gold is undertaken at ALS Perth, WA by 30g
Fire Assay with an AAS finish to a lower detection limit
of 0.01ppm Au using ALS technique Au-AA25.

Bulk-leach analysis for gold is also undertaken by ALS
Perth, WA on selected samples from the Au-AA25
method. The bulk leach method utilises a ~2kg sample
using ALS technique Au-AA15. Navarre does this to
check for the effects of nuggety gold particularly in
know regions containing this effect.

ALS also conduct a 35 element Aqua Regia ICP-AES
(method: ME-ICP41) analysis on each sample to assist
interpretation of pathfinder elements.

A review of certified reference material and sample
blanks inserted by the Company indicate no significant

Internal laboratory QAQC checks are reported by the
laboratory and a review of the QAQC reports suggests
the laboratory is performing within acceptable limits.
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.

Samples are verified by database consultants (Geobase)
and Navarre geologists before importing into the drill
hole database.

No twin holes have been drilled by Navarre during this
program.

Primary data was collected for drill holes using a
Geobase logging template on a Panasonic Toughbook
laptop using lookup codes. The information was sent to
a database consultant for validation and compilation
into a SQL database.

Reported drill results were compiled by the Company’s
Exploration Manager and verified by the Managing
Director.

No adjustments to assay data were made.
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.

All maps and locations are in UTM Grid (GDA94 zone
54).

All drill collars are initially measured by hand-held GPS
with an accuracy of+3metres. On completion of
program, a contract surveyor picks-up collar positions
utilising a differential GPS system to an accuracy of
+0.02m.

A topographic control is achieved via use of DTM
developed from a 2005 ground gravity survey
measuring relative height using radar techniques.

Down-hole surveys were taken every 30m on the way
down to verify correct orientation and dip then multi-
shots taken every 6m on the way out of the drill hole.
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.

Variable drill hole spacings are used to test targets and
are determined from geochemical, geophysical and
geological data together with historic mining
information.

Drilling reported in this program is on a nominal
80x80m drill pattern believed to be sufficient to
establish geological and grade continuity and will be
used to estimate an inferred mineral resource.

compositing
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 drill orientation is attempting to drill perpendicular
to the geology and mineralised trends previously
identified from earlier drilling. Due to the early stage of
exploration it is unknown if the drill orientation has
introduced any sampling bias. This will become more
apparent as further drilling is completed.
Sample
security

The measures taken to ensure sample security.

Chain of custody is managed by internal staff. Drill
samples are stored on site and transported by a
licenced reputable transport company to a registered
laboratory in Pooraka, SA (ALS Laboratories). At the
laboratory samples are stored in a locked yard before
being processed and tracked through preparation and
analysis.
Audits or

land tenure
status

Type, reference name/number, location and
ownership including agreements or material
issues with third parties such as joint ventures,
partnerships, overriding royalties, native title
interests, historical sites, wilderness or national
park and environmental settings.

The security of the tenure held at the time of
reporting along with any known impediments to
obtaining a licence to operate in the area.

The Resolution and Adventure prospects are located
within Navarre’s 100% owned “Stawell Corridor Gold
Project” comprising granted exploration licence ELs
5476, 5480, 6525, 6526, 6527, 6528, 6702 & 6745.

The tenements are current and in good standing.

The project area occurs on a combination of freehold
and crown land.

Two Crown land blocks south of the Irvine basalt dome,
subject to Native Title applications, are under separate
exploration licence applications currently being
considered by Department of Earth Resources
Regulation, Victorian Government.
Exploration
done by other
parties

Acknowledgment and appraisal of exploration by
other parties.

Centaur Mining & Exploration held licence EL 1224 in
the 1980s and conducted surface mapping, and shallow
RAB drilling along road verges in proximity to the Irvine
prospect. The main focus of their exploration activities
became the Mt Ararat base-metal sulphide deposit
further to the SW.

CRA Exploration held licences EL 2651 & EL 3429 (which
were amalgamated into EL 3450) in the early 1990s. It
was recognised that basalt lavas and associated meta-
sediments at the northern end of the field held gold
potential of the Stawell-style (which itself was relatively
poorly understood at that time). CRA drilled 12 RC holes
(average 48m depth) and 2 diamond holes in the Irvine
area. This work was initially focused along two north-
trending outcrops of ironstone to the west of the Irvine
Basalt, now referred to as the Great Western Trend (or
Stawell Fault). Significant gold grades of 4m @ 0.88 g/t
Au (RC92AA021 from 32m) and 2m @ 2.84 g/t Au
(RC92AA027 from 24m) were recorded. Mapping and
rock chip sampling across the entire Ararat Goldfield
was also undertaken at this time with several >1 g/t Au
results obtained.

A single diamond drill hole following up two shallow RC
holes on the western flank of the Irvine Basalt
generated a 0.5m @ 7.2 g/t Au intersection from 86.5m
in a “classic Magdala footwall sequence” of high
arsenopyrite and pyrrhotite from meta-sediments in
DD92AA254. This was the only hole to pass through

the Irvine basalt contact.

From 1995 to 1996, under Joint Venture with CRAE,
Stawell Gold Mines undertook exploration which
included 4 lines of shallow vertical air-core drilling
across the trend of the Irvine Basalt. Owing to weather
and drill penetration difficulties, no basalt contacts were
intersected in any SGM holes and no significant gold
results were obtained. The air-core program helped
deduce the broad outline of the western basalt contact.
A few selected trays from CRAE’s regional drill program
are held by the Geological Survey of Victoria in their
core farm facility in Werribee.

Navarre has reviewed and assessed all previous
exploration results available in the public domain.
Geology
Deposit type, geological setting and style of
mineralisation.

The project areas are considered prospective for the
discovery of gold deposits of similar character to those
in the nearby Stawell Gold Mine, particularly the 4Moz
Magdala gold deposit. The Stawell Goldfield has
produced approximately 5 million ounces of gold from
hard rock and alluvial sources. More than 2.3 million
ounces of gold have been produced since 1980 across
more than 3 decades of continuous operation.
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.

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.

Reported results are summarised in Figures 2-3 and
Tables 1-3 within the main body of the announcement.

Drill collar elevation is defined as height above sea level
in metres (RL).

Drill holes were drilled at an angle deemed appropriate
to the local structure and stratigraphy and is tabulated
in Table 1 of this release.

Hole length of each drill hole is the distance from the
surface to the end of hole, as measured along the drill
trace.

Data
aggregation
methods

In reporting Exploration Results, weighting
averaging techniques, maximum and/or minimum
grade truncations (e.g. 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.

All reported assays have been average weighted
according to sample interval.

No top cuts have been applied.

An average nominal 0.8g/t Au or greater lower cut-off
is reported as being potentially significant in the context
of this drill program.

No metal equivalent reporting is used or 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 (e.g. ‘down hole length, true width not
known’).

Estimated true widths are based on orientated drill core
axis measurements and are interpreted to represent
between 30% to 80% of total downhole widths.
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.

Refer to diagrams in body of text
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.

All drill hole results received and pending have been
reported in this announcement.

No holes are omitted for which complete results have
been received.
