MULTIPLE HIGH PRIORITY DRILL TARGETS IDENTIFIED AT NEPEAN DEEPS

Highlights

  • Down-hole electromagnetics (DHEM) survey completed on the first Nepean Deeps drill-hole NPDD008 has identified three off-hole conductors centred at 540m, 1,025m and 1,230m down-hole

  • Down-hole magnetometric resistivity (DHMMR) survey completed on drill-hole NPDD008 also identified one clear off-hole anomaly at 1,230m down-hole

  • The DHEM and DHMMR conductors together with the 78m of prospective komatiitic ultramafics intersected over four intervals in NPDD008 provide high priority drill targets with the next drill-hole commencing this week

  • Assay and DHEM results from regional RC drilling at Nepean have identified multiple targets for follow-up drill testing

Auroch Minerals Limited ( ASX:AOU ) ( Auroch or the Company ) is pleased to announce that down-hole geophysical surveys have been successfully completed on the first drill-hole NPDD008 in the maiden diamond drill programme into the Nepean Deeps target. The drill programme was designed to test for down-plunge extensions to the high-grade nickel sulphide mineralisation below the historic Nepean mine at the Nepean Nickel Project in Western Australia (Auroch Minerals 80%).

The DHEM survey successfully identified three off-hole conductors within a radius of approximately 100–150m from drill-hole NPDD008 that are potentially indicative of well-developed nickel sulphide mineralisation (Figure 1, Table 1).

The uppermost DHEM conductor is centred at 540m down-hole, proximal to the upper ultramafic intersected in NPDD008. This highly prospective drill target is also proximal to the historic Nepean mine workings, and will be the first of the DHEM conductors to be drill tested with the next diamond hole commencing this week.

The central off-hole DHEM conductor is approximately 1,025m down-hole and is located where the original footwall contact of the Nepean mine nickel sulphide mineralisation was projected down-dip, coincident with an area of stronger seismic reflectors, making it a very strong drill target.

The lowermost off-hole DHEM conductor is centred between 1,220–1,240m down-hole and correlates with an ultramafic intersected between 1,210.5-1,233m. A clear DHMMR anomaly has also been defined in this area centred at 1,245-1,255m down-hole, adding further potential to this conductor as a drill target for nickel sulphides.

Auroch Managing Director Aidan Platel commented :

“The high potential for significant nickel sulphide mineralisation at the Nepean Deeps target continues to strengthen. Our maiden drill-hole NPDD008 into the Nepean Deeps target identified 78m of prospective komatiitic ultramafic rocks over four zones, which seemingly correlate to the four zones of ultramafics recognised in the mine stratigraphy in the old Nepean mine.

The DHEM and DHMMR surveys have built on this prospectivity, identifying three anomalous conductors that correlate to the intervals of komatiitic ultramafics. All three conductors have the potential to represent significant well-developed nickel sulphide mineralisation, and hence all three are high-priority drill targets to be tested by our ongoing diamond drill programme.

ASX ANNOUNCEMENT 20[th] October 2021

==> picture [163 x 43] intentionally omitted <==

The shallowest of the conductors is in close proximity to the historic mine workings and hence will be the first tested by the next diamond drill-hole into the Nepean Deeps target area, to commence later this week.

The long-awaited results from our second phase of regional exploration drilling at Nepean have also successfully defined several strong drill targets with the potential to host significant nickel sulphide mineralisation, to be tested by the next campaign of regional drilling that is currently being planned.

The enormous prospectivity of the Nepean Project is really beginning to become apparent, and we will continue with our aggressive exploration programmes as we push forward to finding that potential new nickel sulphide discovery! ”

Technical Discussion – Nepean Deeps

The upper DHEM conductor is centred at 540m down-hole with a conductance of 2,000-5,250 Siemens, a 60-80m strike and a 120-130m depth extent. The EM plate is modelled steeply dipping to the west-southwest and is proximal to the upper ultramafic intersected from 481-513m.

The central off-hole DHEM conductor is approximately 1,025m down-hole with a conductance of 2,500-3,000 Siemens, a 90m strike and a 100m+ depth extent. This has a flatter interpreted dip (2050° to the west-southwest) but occurs west of the drill-hole. This conductor is also where the original footwall contact was projected down-dip, and coincides with an area of stronger seismic reflectors, making it a very strong drill target.

The lowermost off-hole DHEM conductor is centred between 1,220–1,240m down-hole with a conductance of 4,000-6,000 Siemens, and correlates with an ultramafic intersected between 1,210.51,233m. Interestingly, a flatter dip is interpreted (20-50° to the west-southwest) than the steeper dipping stratigraphy above the pegmatite intrusion.

Furthermore, a clear DHMMR anomaly has been defined in the lower section of NPDD008 centred at 1,245-1,255m down-hole which may be related to the lowermost DHEM anomaly, adding further potential to this conductor as a drill target for nickel sulphides.

Higher up in NPDD008 a broad DHMMR anomaly is apparent between 460-700m down-hole. Further assessment is required as to whether this is a legitimate bedrock conductor or related to background responses.

A technical review of the results from NPDD008 has been completed and follow-up drilling is confirmed to commence later this week. The next drill-hole into the Nepean Deeps target area will be collared approximately 80m west of the NPDD008 collar to test the upper 1A/1B DHEM plates (Figure 1).

Results – Nepean Regional Exploration

Assay results have been received for 14 out of the 19 reverse circulation (RC) drill-holes completed in the second phase of regional drilling at Nepean, with significant intersections shown in Table 2. Anomalous nickel intersections (>0.3% Ni) were intersected in several RC holes, however further review is being conducted to determine if these are the result of disseminated nickel sulphide mineralisation or oxidisation of the ultramafics, or in some cases, both. Elevated gold (>0.5g/t Au) was intersected in several drill-holes with the best intersections from NPRC068 located 800m southeast of Nepean mine (Figure 2), including 1m @ 14.05g/t Au from 67m and 2m @ 0.85g/t Au from 78m . Both intersections occur in altered basalt, with the first intersection on contact with an ultramafic and the second associated with quartz veining. In addition, there are several samples with >100ppb Au around these two intersections and this target may be followed up with additional drilling.

Elevated PGEs (Platinum Group Elements; >50ppb Pt+Pd) results were also observed in several of the recent regional RC drill-holes. The most significant are shown in Figure 2. NPRC066 intersected 1m @ 903ppb Pt+Pd from 32m which occurs in a weathered ultramafic. In addition, NPRC075 intersected 10m @ 138ppb Pt+Pd from 209m and NPRC076 intersected 3m @ 148ppb Pt+Pd from 235m, with both intersections in a mafic amphibolite 1.5km south-east of the Nepean mine. These are unusually high PGE results for mafics (~9% MgO) and may also be followed-up with additional drilling.

DHEM surveys have also been completed on all RC holes in the second phase of regional drilling at Nepean , with two new off-hole conductors identified in drill-holes NPRC067 and NPRC069/NPRC070 (Table 3, Figure 2). NPRC067 was drilled approximately 900m southeast of the Nepean mine and the DHEM survey identified a clear moderate strength anomaly of 1,750-2,250 Siemens centred 110-115m down-hole. Prospective ultramafics were intersected between 125-193m down-hole and the plate warrants follow-up drill testing for potential nickel sulphide mineralisation.

DHEM surveys in drill-holes NPRC069 and NPRC070 both identified the same off-hole conductor 2.2km south of the Nepean mine associated with the western ultramafic unit. The anomaly has a low conductance of 250-400 Siemens, but relates to the basal contact of the ultramafic unit intersected in NPRC069 (basal contact 70m) and NPRC070 (basal contact 74m). High-grade and high-tenor matrix nickel sulphides mined at Nepean have low EM conductance and therefore these anomalies require follow-up drill testing for potential nickel sulphide mineralisation .

CRITERIA EXPLANATION 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.

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 (eg ‘reverse circulation
drilling was used to obtain 1m samples
from which 3kg 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 (eg
submarine nodules) may warrant
disclosure of detailed information.
Drilling
Auroch Minerals Limited:

Nickel mineralisation at Nepean has been
sampled from the following drilling
techniques:

Diamond Core - half core samples with a
maximum of 1.2m and minimum 0.3m
length.

RC drilling - 1m samples of pulverised
chips, approximately 3kg’s is collected in
individual calico bags

Air Core drilling creates single metre
sample of drill chips, however samples are
composited every 3 metres, with the end
of hole sample consisting of a 1m sample.
Historic:

Nickel mineralisation at Nepean has been
sampled from Reverse Circulation (RC) 1m
chip samples & Diamond core samples.

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.
Auroch Minerals Limited:

Drill data spacing of historic drill data is
sufficient to establish the degree of
geological and grade continuity
appropriate for this stage of exploration
and understanding of mineralisation
Historic:

Typically sampled in 1-4 metre intervals,
skipping intervals of no interest and
increasing the frequency of sampling
depending on the geology observed in
diamond drill core.

Drill data spacing of historic drill data is
sufficient to establish the degree of
geological and grade continuity
appropriate for estimating an Inferred Ni
Resource.
Air Magnetic Survey:

Flight-line spacing50-100m
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.
Auroch Minerals Limited:

Drill holes azimuth is nominally planned
perpendicular to stratigraphic strike

Drill hole dip is regarded suitable for
subvertical stratigraphy and provides a
near true width intersection to minimise
orientation bias.
Historic:

Historical drill holes were oriented, as far
as reasonably practical, to intersect the
centre of the targeted mineralised zone
perpendicular to the interpreted strike
orientation of the mineralised zone.

The geometry of drill holes relative to the
mineralised zones achieves unbiased
sampling of this deposit type.

No orientation-based sampling bias has
been identified.
Sample security
The measures taken to ensure sample
security.
Auroch Minerals Limited:

Drill samples are collected in labelled
polyweave bags and closed with tight zip
ties.

Samples are transported within 1-2days of
hole completion by field staff directly to
ALS laboratories.

Diamond core samples are dispatched
once all cutting and sampling of drill core
is complete. Drill core is maintained in a
secure core yard.
Historic:

It is assumed that due care was taken
historically with security of samples during
field collection, transport and laboratory
analysis.

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’).

Most drill holes are orthogonal to the
orientation of stratigraphy and
mineralisation.
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.

Relevant diagrams have been included
within 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.

All results related to mineralisation at
Nepean have been previously reported in
the Significant Intersections 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

geotechnical and rock characteristics;
potential deleterious or contaminating
substances.

No other substantive data exists.

possible extensions, including the main
geological interpretations and future drilling
areas, provided this information is not
commerciallysensitive.

Auroch is currently reviewing all Nepean
Nickel Project data to determine where
further drilling is warranted. If it is
determined that additional drilling is
required, the Company will announce such
plans in due course.
