ASX ANNOUNCEMENT 22 April 2021
ADDITIONAL TRACE MAGMATIC NICKEL SULPHIDES IDENTIFIED IN MULTIPLE DRILL HOLES AT FRASER RANGE
Constellation Resources Limited (the “Company” or “Constellation”) is pleased to provide the following update on its exploration activities at the Orpheus Project in the Fraser Range of Western Australia.
HIGHLIGHTS
-
Completion of 15 infill air-core (“AC”) drill holes over tenement E28/2403, assays pending.
-
Additional petrological samples continue to return trace levels of magmatic nickel-copper (“NiCu”) sulphides in multiple holes over the extensive Eyre Ni-Cu-Co-PGE anomaly. With previously reported petrology, trace levels of nickel sulphides can now be mapped in a fertile intrusive unit over a 2km strike length, confirming scale prospectivity.
-

AIRCORE DRILLING AND PETROLOGICAL SAMPLES – E28/2403
Air-Core Drilling
The latest AC infill drilling program was completed during March for a total of 1,535 metres with 13 effective holes reaching basement of a proposed 20-hole program. The infill drilling program targeted a number of Ni-Cu-Co-PGE geochemical footprints including the extensive (3km by 0.4km) Eyre Anomaly (Figure 1). Assays for the latest AC program are pending. The Company plans to recommence AC drilling this quarter, with an aim to complete the northern Eyre Anomaly infill holes to approximately 100 metre centres. The results from the current and proposed AC drilling programs will be processed to optimise the locations of an anticipated reverse circulation (“RC”) drilling and downhole electromagnetics program.
Petrological Samples
Additional optical petrological analysis by Minerex Services Pty Ltd from holes KAC0082 and KAC0147 located within the middle and northern sections of the Eyre Anomaly, have confirmed trace levels of magmatic Ni-Cu sulphides hosted in fertile olivine gabbronorite intrusive units (Figures 1 and 2).
Combined with previously reported Eyre Anomaly petrology results at the southern end of the anomaly, the magmatic Ni-Cu sulphide occurrences have now been identified over a 2km strike length ( refer ASX announcement dated 19 January 2021 for further details ). The Ni-Cu sulphide occurrences in addition with the associated pathfinder (Ni-Cu-Co-PGE) regolith anomaly, both track along the base of an interpreted large, and highly prospective fertile olivine bearing intrusion suite.
The link between nickel sulphides with associated pathfinder geochemistry is considered highly promising. The results underscore the nickel sulphide fertility of the intrusions and its prospectivity to potentially host an economically viable deposit in the tenement area.

HISTORIC MCPHERSON PROSPECT - E63/1282
The Company recently completed a review of historic and newly released open file work programs over its tenement, E63/1282 and as such has reassessed the prospectivity of the historic McPherson Prospect (“McPherson”) located in the north-east corner of the tenement. McPherson is a coherent Ni-Cu soil anomaly that resides directly above a north-west trending magnetic unit that could represent a favourable intrusive unit to host nickel sulphides (Figure 3). McPherson is located 30km south west of Independence Group Limited’s Nova nickel mine (Figure 5).
The McPherson soil anomaly was originally delineated by Enterprise Metals Limited (“Enterprise”) (ASX: ENT) in 2013 (refer ENT ASX announcement 24 July 2013 for further details). The soil anomaly was defined on a 200 metre x 100 metre grid with individual maximum values reported up to 104ppm Ni, 73ppm Cu and 28 ppm Co. Enterprise also reported the results of a helicopter borne electromagnetic survey system (“HeliTEM”) that covered the areas of anomalous Ni-Cu soil geochemistry. Analysis of the HeliTEM data indicated a number of second order late time electromagnetic responses, some of which were coincident with the Ni-Cu anomalies at the McPherson area. All late time responses generated by this program remain untested by drilling.

Figure 3 and 4: Left - Ni-Cu soil geochemical footprints over first derivative aeromagnetics. Right - Proposed MLTEM survey over VTEM and HeliTEM anomalies.
A review of open file geophysical datasets was recently completed by Russell Mortimer from Southern Geoscience Consultants. The review incorporated a high quality 2013 open file versatile time domain electromagnetics (“VTEM[Max] “) dataset that was commissioned by a peer exploration company on the adjoining tenement. The flight lines of the VTEM[Max] survey were extended beyond the adjoining tenement, fortuitously covering the McPherson soil anomaly. The review of the superior VTEM[Max] dataset indicates the presence of a first order more coherent late time bedrock conductor beneath the McPherson soil anomaly (Figure 3 and 4).

22 April 2021
A recent reconnaissance trip by the Company has confirmed the area around McPherson has no outcrop and the basement units are concealed under cover. No historic drill holes were identified or surface cultural effects that may lead to false positive airborne electromagnetic responses. Three small soil traverses were also completed by the Company comprising 21 samples over the McPherson Ni-Cu soil anomaly for Au and PGEs (historically no PGE results have been collected over the tenement). Low order results up to 7ppb Au and 2ppb (Pt+Pd) were returned (Refer to Appendix 1 for details results).
In light of the above review, a high priority surface high powered moving loop electromagnetic survey (“MLTEM”) has been approved by the Company to cover the McPherson soil anomaly and ground truth selected airborne electromagnetic anomalies of interest. The proposed MLTEM survey comprises of 13 lines for 14.5kms and is expected to commence in the coming weeks (Figure 4). If a MLTEM bedrock conductor of interest is identified, RC drilling is proposed as the next step as cover is not thought to be excessive.

Appendix 2: JORC Code, 2012 Edition – Table 1
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 (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 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 (eg submarine nodules) may warrant disclosure of detailed information. |
Aircore (AC) drilling was undertaken to generate representative metre samples from the surface to the bottom of hole. The non-transported portion for each hole was spear sampled to create a 1 metre representative sample. All samples weighed between 2-3kg. Samples had generally minimal dampness with isolated wet samples encountered. Samples were sent to an independent commercial assay laboratory. All assay submitted for sample preparation comprised oven drying, jaw crushing, pulverising and splitting to produce a representative assay charge pulp. Samples to be analysed using four Acid digest and read by ICP‐OES/ ICP‐MS, reporting 48 elements including Ag, Al, As, Ba, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn and Zr. Soil samples were sieved from a sample derived from a 20cm to 30cm hole. Sample weight ranged from 50-200g, Soil preparation comprised oven drying, pulverising and splitting to produce a representative assay charge pulp. Samples analysed used a 25g charge and read by fire assay ICP-MS for Au, Pt and Pd |
| Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
Aircore drilling was undertaken by Raglan Drilling using a 90mm drill bit. |
| 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. |
Poor sample recoveries were visually estimated and recorded on sample log sheets. The sample cyclone is routinely cleaned at the end of each rod run (3m) or when deemed necessary. There is insufficient data to determine if there is a sample bias between sample recoveries and assay grades. |
| 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 metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Geological logging of air core drill spoils was done on a visual basis for lithology, grainsize, mineralogy, colour and weathering. Logging was further aided with the collection of 1m chip trays. All drill holes were logged in their entirety. Petrological analysis and descriptions were undertaken by independent petrological consultant Minerex Services Pty Ltd. |

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.

(2-3kg). Both damp and dry samples were collected. QAQC reference samples and duplicates were routinely submitted with each sample batch. The size of the sample is considered appropriate for the mineralisation style sought and for the analytical technique used. Soil samples were collected using a 75 micron sieve |
| 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Aircore samples will be analysed for a multi-element suite by ICP-MS following a four-acid digest. These assay methods are considered appropriate. QAQC standards and duplicate samples were included routinely (approximately 1 for every 40 samples). In addition, internal laboratory batch standards and blanks were also undertaken adding to reliance is placed on laboratory procedures adding to the assurance of the reported results. All samples submitted to NATA accredited provider - Minanalytical Laboratory Services Australia Pty Ltd, located in Perth using methods; MA4020; 48 Elements ICP-OES / ICP-MS Package (multi-elements) and FA25MS3, 25g fire assay ICP-MS package. |
| 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. |
Field data is collected on site using a standard set of logging. Data is then upload into the access database. Assays are as reported from the laboratory and stored in the Company database and have not been adjusted in any way. Significant intersections were verified by senior exploration personnel. |
| 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. |
The drillhole collar and soils were surveyed with a handheld GPS unit with an accuracy of ±5m which is considered sufficiently accurate for the purpose of the reconnaissance drill hole program. All co-ordinates are expressed in GDA94 datum, Zone 51. Regional topographic control has an accuracy of ±2m based on detailed DTM data collected in 2019 aerial surveys. |
| 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. |
Aircore drilling spacing was at a nominal 500m x 400m with latest infill holes to 100m spacings on selected traverses. Drillholes were sampled in the residual portion of the hole with the occasional need to sample into the transported cover if the regolith profile was not well developed. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The targeted deposit types and styles of mineralisation are nickel- copper-cobalt (Ni-Cu-Co) magmatic sulphide systems such as the Nova-Bollinger deposit and Tropicana style gold mineralisation. |
| 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: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole 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. |
Refer to table of drillhole collars in Appendix 1. |
| 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. |
The weighted averages of individual drill holes are calculated. |
| 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’). |
Drillhole intercepts/intervals are measured downhole in metres. |
| 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. |
Project and drillhole location maps have been included in the body of the report. |
| 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 |
