ACN 119 057 457, AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT, 31 August 2021

HIGHLIGHTS

- The Cascata Prospect is a new discovery interpreted to be a likely volcanogenic massive sulphide (VMS). Over 6km of strike length has been traversed, with sulphides discovered consistently at surface. The area of interest is approximately 15km2 and is all within the Company's existing Ryberg licence. Drilling has commenced.

- SODD003 (Sortekap Prospect) is complete and intersected 78m of prospective quartz veins hosting sulphide mineralisation within amphibolite. The target is gold, with previous surface samples in the vicinity grading up to 2.7g/t gold.

- SODD002 (Sortekap Prospect) is complete and intersected ~6% disseminated chalcopyrite + pyrrhotite over 7.1m from 188.5m downhole. Zones of disseminated pyrite were also encountered.

- 1 x drill rig has mobilised to an electromagnetic target at the Miki Prospect.


Conico Limited (ASX: CNJ) ("Conico" or "the Company") and its wholly owned subsidiary Longland Resources Ltd ("Longland") is pleased to announce that a new discovery interpreted as a likely volcanogenic massive sulphide (VMS) has been discovered and a drilling has commenced. SODD002 and SODD003 have been completed at Sortekap, and hole MIDD008 at the Miki Prospect.

Longland CEO Thomas Abraham-James said:

"The discovery of a potential new VMS occurrence at Cascata typifies the prospectivity of Greenland. Over 6km of strike has been traversed by foot with lithologies prospective for VMS accompanied by consistent sulphide mineralisation observed, justifying immediate drilling. Meanwhile we continue to see mineralisation in drill holes completed at Miki and Sortekap."

The newly discovered Cascata Prospect

Reconnaissance exploration was successful in identifying outcropping copper and iron sulphides, referred to as the Cascata Prospect (figure 1). The mineralisation is present as pyrite, chalcopyrite and bornite in massive, semi-massive, stockwork and disseminated forms, associated with black shales, rhyolitic volcanism, and underlying amphibolite (figures 2-7). Field investigations conducted thus far suggest that Cascata may potentially be a Volcanogenic Massive Sulphide (VMS) occurrence, with over 6km of strike length traversed by foot and an area of interest covering ~15km2.

Drilling has commenced at Cascata and is situated on the upper end of the stratigraphy. The prospect is situated within the existing Ryberg license and is readily accessible, located only 6km from the coast and has abundant fresh water sources.

Sortekap Prospect: Drill-hole SODD003

Drill-hole SODD003 targeted gold mineralisation hosted in amphibolite (figure 9) and was positioned to drill perpendicular to quartz veins where previous surface sampling returned grades of up to 2.7g/t gold.

The drill-hole was successful in passing through 78m of prospective quartz-bearing amphibolite, commencing at surface (figure 8). The quartz veins frequently contained trace/disseminated sulphides which is encouraging as published literature on the gold occurrences at Sortekap state that gold mineralisation is linked to the presence of trace sulphides (particularly arsenopyrite) in amphibolite. Sulphides encountered do include arsenopyrite, in conjunction with pyrite and chalcopyrite (figures 10-11).

The hole was terminated in serpentinite and the rig has since moved to the next drill-hole at the Miki Prospect, drilling an electromagnetic (EM) anomaly that was identified in the 2020 EM survey.

Sortekap Prospect: Drill-hole SODD002

Located in the Sortekap Prospect, drill-hole SODD002 targeted an Induced Polarisation (IP) chargeable anomaly. The drill-hole was successful in intersecting sulphide mineralisation over multiple intervals, the most significant being 7.1m commencing at 188.5m downhole and consisting of ~6% disseminated chalcopyrite and pyrrhotite. Deeper in the hole there are zones of up to 20% disseminated pyrite (figure 12).

The hole was extended in length to a total depth of 356m in order to intercept the serpentinite seen in hole SODD001. This ties the geology of the two Sortekap drill-holes together, giving a firmer understanding of the regional stratigraphy.

Miki Prospect: Drill-hole MIDD008

This hole targeted magmatic sulphides associated with the Miki Fjord Macrodyke (figure 16). From 78.9m to end of hole (312m), MIDD008 intercepted a quartz - potassic feldspar - mica assemblage (figures 13 to 14) that contains veinlets of molybdenite (between 1 - 2% when encountered), and trace occurrences of chalcopyrite (~2% when encountered, figure 15).

Encountering such mineralisation is unexpected, but not surprising considering the location's proximity to nearby known systems such as the Flammefjeld porphyry molybdenum project located 38km to the west.

The drill-hole was terminated at 312m drilled depth while still in the altered country rock, with the rig being re-tasked to the Cascata Prospect.

By order of the board.

JORC Code, 2012 Edition
Section 1: Sampling Techniques and Data

CriteriaJORC Code ExplanationCommentary
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. * Sampling of MIDD008, SODD002 & SODD003 was conducted using standard industry practices with diamond drilling. Magnetic readings were taken using a Reflex EZ-Trac downhole survey tool.
 Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. * Drill-holes MIDD008, SODD002 & SODD003 were angled to optimally intersect the interpreted contact with an IP conductor or adjacent to lithologies of interest.
 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. * Mineralisation in drill-holes MIDD008, SODD002 & SODD003 has not been quantitively determined and is awaiting assay. The determination in this report is qualitative, based on visual observation made by the Competent Person who is a geologist on site.
Drilling techniquesDrill 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.). * Wireline diamond drilling using a 56.5mm diameter drill bit and standard tube. The core has not been orientated but has been surveyed using a Reflex EZ-Trac multi-shot tool. The drill rig is a CDI 500 heli-portable fly rig operated by Cartwright Drilling Inc.
Drill sample recoveryMethod of recording and assessing core and chip sample recoveries and results assessed. * All drill core has been geotechnically logged with core recovery measured per drill core run (3m).
 Measures taken to maximise sample recovery and ensure representative nature of the samples. * The drill crew was notified of the target depth and likelihood of intersecting sulphides, accordingly they eased pressure on the drill bit from that depth onward to minimise the chance of core destruction. All drill core was then placed in trays with lids to ensure that no core was lost during transportation from the drill site to core logging facility. The drill core was then reconstructed into continuous runs on an angle iron cradle by the geologist. Depths were checked against depths indicated on the core blocks.
 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. * Not applicable as no assays have been conducted to date.
LoggingWhether 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. * All drill core has been geologically and geotechnically logged by a qualified geologist to a level of detail that supports appropriate Mineral Resource estimation, mining studies and metallurgical studies.
 Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. * The logging is qualitative. All drill core was photographed.
 The total length and percentage of the relevant intersections logged. * Drill-holes MIDD008, SODD002 & SODD003 have been logged in full.
Sub-sampling techniques and sample preparationIf core, whether cut or sawn and whether quarter, half or all core taken. * No sampling has been undertaken.
 If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. * Not applicable as the drill-hole is core.
 For all sample types, the nature, quality and appropriateness of the sample preparation technique. * Not applicable as no sampling has been undertaken.
 Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. * Not applicable as no sampling has been undertaken.
 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. * Not applicable as no sampling has been undertaken.
 Whether sample sizes are appropriate to the grain size of the material being sampled. * Not applicable as no sampling has been undertaken.
Quality of assay data and laboratory testsThe nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. * Not applicable as no assaying has occurred.
 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. * Downhole magnetic readings were taken using a Reflex EZ-Trac. Readings were taken every 3m at completion of drilling, with the survey beginning at bottom of hole and working up. The tool protruded beyond the drill string by 3m to ensure no interference from the rods. The magnetic roll is 0 to 360 with an accuracy of ±0.35 . The magnetic range is 0 to 100,000 nT with an accuracy of ±50 nT.
 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. * Not applicable as no sampling or assaying has occurred.
Verification of sampling and assayingThe verification of significant intersections by either independent or alternative company personnel. * Consultants utilised by the Company have verified the findings of the on-site geologists.
 The use of twinned holes. * Not applicable as no twinned holes have been drilled.
 Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. * All logging data was entered into a computer on site, with daily backups taken and stored on hard drives and the cloud.
 Discuss any adjustment to assay data. * Not applicable as no assaying has occurred.
Location of data pointsAccuracy 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. * Drill-holes MIDD008, SODD002 & SODD003 were located using a handheld Garmin GPS with an accuracy of ±4m.
 Specification of the grid system used. * UTM WGS84 Zone 25N.
 Quality and adequacy of topographic control. * Topographic information was sourced from the Greenland Mapping Project (GIMP) digital elevation model (30m accuracy).
Data spacing and distributionData spacing for reporting of Exploration Results. * Not applicable as the drill-holes are targeting specific geological and IP targets.
 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. * Not applicable as the drill-holes are targeting specific geological and IP targets.
 Whether sample compositing has been applied. * Not applicable as no sampling has occurred.
Orientation of data in relation to geological structureWhether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. * The strike and dip of drill-holes MIDD008, SODD002 & SODD003 were designed to intersect an IP target/lithological unit at an adjacent angle, not along strike. Therefore, the sampling conducted by the drill-hole is considered unbiased.
 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. * There are no known biases caused by the orientation of drill-holes MIDD008, SODD002 & SODD003.
Sample securityThe measures taken to ensure sample security. * The drill core is stored onboard the Company's charter vessel which is considered highly secure.
Audits or reviewsThe results of any audits or reviews of sampling techniques and data. * No audits or reviews have been carried out at this time.
 



Section 2: Reporting of Exploration Results

CriteriaJORC Code explanationCommentary
Mineral tenement and land tenure statusType, 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 Ryberg Project is wholly within Mineral Exploration Licences 2017/06 and 2019/38, located on the east coast of Greenland. They are held 100% by Longland Resources Ltd, a wholly owned subsidiary of Conico Ltd.
 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 tenure is secure and in good standing at the time of writing. There are no known impediments.
Exploration done by other partiesAcknowledgment and appraisal of exploration by other parties. * Previous work mentioned (2017 VTEM survey) was planned and managed by Longland Resources Ltd, a wholly owned subsidiary of Conico Ltd.
* Historic rock-chip sampling was conducted by Platina Resources Ltd and University of Leicester.
GeologyDeposit type, geological setting and style of mineralisation. * Deposit types: Magmatic & VMS.
* Geological setting: The project area is located within the North Atlantic Igneous Province (NAIP), a Tertiary volcanic centre that covered an area of approximately 1.3 million km2 in continental flood basalts (6.6 million km3 in volume), making it one of the largest volcanic events in history. Volcanism is associated with the opening of the North Atlantic, and presence of a mantle plume (what is now the Icelandic hotspot). The project area represents an erosional interface where the flood basalts have been removed, revealing the basement geology beneath. The project area is adjacent to a triple junction (failed rift) and consists of Archaean orthogneiss, Tertiary gabbro/flood basalt, and Cretaceous-Tertiary sediments (rift valley basin). Approximately 70% of the geology within the sedimentary basin has been intruded by Tertiary sills that are feeders to the overlying plateau basalts. There are also feeder dykes and layered mafic intrusions - it is likely that there is also a large ultramafic body present at depth, evidence for this is in the form of ultramafic xenoliths brought to surface by magma conduits.
* Style of mineralisation: magmatic copper and nickel sulphides with appreciable cobalt, palladium and gold.
Drill hole InformationA summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
- easting and northing of the drill hole collar
- elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar
- dip and azimuth of the hole
- down hole length and interception depth
- hole length.
* Refer to Annex 1.
 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. * This is not the case.

 
Data aggregation methodsIn 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.
* Not applicable as no sampling or assaying has occurred.
 The assumptions used for any reporting of metal equivalent values should be clearly stated. * Not applicable as no sampling or assaying has occurred.
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').
* The geometry of the mineralisation with respect to the drill-hole angle is not known. All reported lengths are in reference to down-hole length, true width not known.
DiagramsAppropriate 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 Figures 1,4, 5, 6, 7 and 10.
Balanced reportingWhere 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. * Not applicable as no sampling or assaying has occurred.
Other substantive exploration dataOther 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. * Previous exploration results are detailed in:
