Conico Limited ( ASX:CNJ ) ( Conico or the Company ) is pleased to provide an update on exploration activities at the Mt Thirsty Joint Venture ( MTJV ) (Greenstone Resources Ltd (ASX:GSR) 50%: CNJ 50%), where a continuous zone of disseminated sulphides has been intersected as part of the Phase I drill campaign. The Phase I drill campaign is testing for extensions to the recent palladium-platinum-gold-copper-nickel (PGE) discovery by Galileo Mining Ltd (ASX:GAL) (Galileo) located less than 200 metres from the MTJV’s northern tenement boundary. The MTJV is located 16 kilometres NorthNorthwest of Norseman, Western Australia.

Diamond drill hole MTJV001 was the first of twenty holes to be drilled as part of the Phase I drill campaign targeting mineralisation associated with the same geological horizon hosting Galileo’s recent Callisto discovery. MTJV001 was drilled 400 metres along strike from Callisto targeting the modelled contact between the ultramafic rocks of the Mount Thirsty Sill complex and an underlying sedimentary unit. This target horizon had been modelled at between 190 – 220 metres down hole. Importantly, MTJV001 intercepted disseminated sulphides between 190 – 255 metres down hole, validating the comprehensive exploration model compiled over the past weeks by the MTJV in conjunction with a panel of technical experts. MTJV001 intercepted a similar downhole geological sequence as observed at Calisto, namely, weakly disseminated sulphides – disseminated sulphides – heavily disseminated sulphides – altered disseminated sulphides (appendix 1), including:

  • 43 metres of disseminated sulphides in ultramafics from 190 metres downhole;

  • 3 metres of heavily disseminated sulphides in sediments from 233 metres downhole;

  • 19 metres of heavily disseminated sulphides in fluid altered ultramafics from 236 metres downhole.

Geological logging recorded both chalcopyrite and pentlandite, serving to confirm the presence of both copper and nickel which are often associated with PGE mineralisation at Callisto[1,2] .

MTJV001 has been logged, cut, sampled, and submitted for assaying, including palladium, platinum, gold, copper, nickel and rhodium. Final assays are expected within 4-6 weeks. The Phase I drill campaign continues on schedule with the drill rig having now moved further north (only 300 metres from Callisto) and is currently drilling MTRC014D.

Executive Director Guy Le Page, commented :

“The Company is delighted to have intersected a thick continuous zone of heavily disseminated nickel-copper sulphides in the very first hole drilled in this program. Importantly, this hole is interpreted to have intercepted the same geological horizon as that hosting the Callisto discovery, potentially extending the known strike horizon to over 400 metres, while remaining open in all directions. Drill core assays, including platinum, palladium and rhodium are likely to be received within 4-6 weeks. The drill rig has now been moved further north, closer to Callisto, where the continuity of mineralisation both along and across strike will be tested. We look forward to keeping shareholders updated on a regular basis as our understanding of the nature and scale of this recently identified mineralised system develops over the coming weeks.”

BACKGROUND & TECHNICAL DISCUSSION

The Mt Thirsty Project overlies a north-striking sequence of Archaean rocks of the Mount Kirk Formation at the southern end of the Norseman-Wiluna greenstone belt. The Mount Kirk Formation comprises metamorphosed peridotite, pyroxenite, sedimentary rocks and mafic and acid volcanics. Within the area, the Mount Kirk Formation is intruded by two major mafic-ultramafic differentiated sills, the Mount Thirsty Sill and the Mission Sill.

Galileo recently announced (GAL, ASX Announcement, 11 May 2022) the completion of six reverse circulation drillholes at Callisto targeting a mineralised sulphide unit on the contact between an ultramafic sill and a package of sedimentary rocks. An initial appraisal of the results from Callisto by Galileo indicates similarities in mineralisation style to the Platreef deposits on the northern limb of the Bushveld Complex in South Africa. The Platreef deposits are very large in nature and have combined indicated resources of >700Mt at a 1 g/t 3PE+Au cut off3 and contain palladium, platinum, gold, rhodium, copper, and nickel. Significant intercepts from the discovery hole NRC266 drilled by Galileo on their tenure, include[4] :

  • 33 metres @ 2.00g/t 3E5 (1.64g/t Pd, 0.28g/t Pt, 0.09g/t Au), 0.32% Cu & 0.30% Ni from 144m, including;

  • 6 metres @ 2.69g/t 3E (2.21g/t Pd, 0.37g/t Pt, 0.11g/t Au), 0.41% Cu & 0.36% Ni from 159m; and

  • 1 metre @ 3.21g/t 3E (2.66g/t Pd, 0.41g/t Pt, 0.14g/t Au), 0.48% Cu & 0.46% Ni from 176m.

Figure 3: Plan view of Phase I collars and prospective geological horizon.

Importantly for the MTJV, Galileo’s recent discovery at Callisto is only 200 metres from the northern tenement boundary held by the MTJV with the extension of the prospective mineralised horizon onto MTJV tenure supported by geophysics & lithology (CNJ, ASX Announcement, 16 May 2022). Despite extensive shallow drilling over the Mt Thirsty resource area (JORC Inferred and Indicated Resources of 26.9Mt at 0.126% cobalt, and 0.54% nickel, see Appendix 4), the prospective eastern margin remains largely untested (Figure 1) with only 3.5% of all holes drilled at Mt Thirsty penetrating deeper than 100 metres, also noting Galileo’s discovery hole was from 144 metres downhole. As such, an initial review indicates that a further 2.0km of the

prospective mineralised horizon may extend onto the MTJV tenure.

In addition to the untested PGE potential, the MTJV is undertaking a detailed geological review assessing the western margin of the Mt Thirsty licences for lithiumcaesium-tantalum (LCT) potential, with historical drilling and mapping previously documenting pegmatites within the MTJV licence area. Importantly, 150 metres to the west of licences held by the MTJV is the Mt Thirsty pegmatite where Galileo previously reported a series of steeply dipping, north-south trending pegmatites. Six grab samples of micaceous (lepidolite) pegmatite were sampled by Galileo returning an average assay grade of 2.3% Li2O, 1.87% Rb and 476 ppm Ta205[6] .

Cautionary Statement: Identification of sulphides, and reporting of visual results is not considered a proxy or substitute for laboratory analyses. The samples will be despatched for laboratory analysis as soon as possible and results reported upon receipt in accordance with the Company’s continuous disclosure policy.

This announcement is authorised by the Board of Directors.

THE FOLLOWING TABLES ARE PROVIDED TO ENSURE COMPLIANCE WITH THE JORC CODE (2012 EDITION) FOR THE REPORTING OF EXPLORATION RESULTS.

MT THIRSTY PROJECT

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 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 (e.g. submarine
nodules) may warrant disclosure of
detailed information.

Sampling
was
conducted
using
Diamond Core (DD) drilling rig.

For DD drilling, samples were collected
as half-core (NQ2) at geological intervals
defined and mineralisation boundaries and
is considered appropriate for this style of
mineralisation.

Diamond drilling was used to obtain
half-core
samples
of various
lengths
(minimum 0.2m), from which 1-3kg of
material is collected for assaying.

QAQC Standards and Blanks were
collected/inserted
at
a
rate
of
approximately 1 in every 20m (maximum)
through pre-determined mineralised zones.

Samples were sent to an independent
commercial laboratory where samples are
oven dried, crushed, pulverised and split to
produce a 50g charge for fire assay.

Sampling and QAQC procedures are
carried out using Conico’s protocols as per
industry best practice.
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).

DD drilling was HQ2 to approximately
150m, remained of holes was drilled HQ2.
Core was oriented every 3m where possible
using an electronic orientation tool.
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
fine/coarse material.

Core recovery was estimated using the
drillers recorded depth marks against the
length of the core recovered, this is verified
and confirmed by Greenstone staff.

No sample recovery issues have
impacted on potential sample bias.
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

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

Diamond core is cut in half along the
orientation line. The right side of the core is
collected for analysis.

Sample preparation was conducted at
ALS Global laboratories using a fully
automated sample preparation system.
Preparation commences with sorting and
drying. Oversized samples are crushed to
<3mm and split down to 0.5-3kg using a
riffle splitter. Samples are then pulverized
and homogenized in LM5 Ring Mills and
ground to ensure 85% passes <75µm.

The

of accuracy (i.e. lack of bias) and
precision have been established.

Homogenised and pulverised samples
are mixed with flux composed of PbO and
SiO2 with variable amounts of borax, soda
ash and other reagents. The flux and
sample are mixed, then heated at high
temperature (>1,000°C) to decompose rock
lattices and allow precious metals within the
sample to be collected into a lead button.
The button is placed in a porous cupel and
heated again in an oxidising environment
to convert lead to lead oxide that is
absorbed into the cupel, leaving the
precious metals behind as a doré bead or
prill. The gold, platinum and palladium
content of the prill is then determined
through Inductively Coupled Plasma Mass
Spectrometry (ICP-MS). The detection level
for
the
Fire
Assay/AAS technique is
0.001ppm for Palladium (Pd) and Gold (Au) ,
0.0005 for Platinum (Pt).

Rhodium (Rh) analysis is carried out in a
similar manner to PGM by lead collection
fire assay, with the additional step of gold
inquarting during the fusion process and
modified cupellation. Analysis is carried out
