ASX ANNOUNCEMENT 20 January 2020
AIRBORNE MAGNETIC AND GRAVITY SURVEYS COMPLETED TEN HIGH PRIORITY TARGETS IDENTIFIED
Constellation Resources Limited (“the Company” or “Constellation”) is pleased to announce that the Company has completed both a detailed high-resolution airborne magnetic survey and a semi-regional gravity survey over tenements E28/2403 (70% Constellation, 30% Enterprise Metals Limited (ASX: ENT)) and E28/2738 in the Fraser Range. The processing and interpretation of these surveys has led to the identification of ten high priority drill targets across the tenements, on which the Company intends to commence an air-core drilling program in the next quarter.
The completion of these initial geophysical programs represents the early stages of a systematic exploration approach to target nickel sulphides across the Company's northern landholdings. The datasets obtained from the surveys will assist in identifying the presence of potential mafic intrusions (host of nickel-copper-cobalt mineralisation in the Fraser Range) that may be concealed under cover.

HIGH PRIORITY TARGETS IDENTIFIED
Geophysical datasets from both the detailed high-resolution airborne magnetic survey and semi-regional gravity survey over tenements E28/2403 and E28/2738 have now been processed and interpreted by Peter Muccilli of Unearthed Geological Consulting and Russell Mortimer of Southern Geoscience Consultants. The processing and interpretation of the datasets has led to the identification of ten high priority drill targets across the two tenements.
Each target has been identified as a potential mafic intrusion that is concealed under cover (Figures 1 and 2) and exhibits a circular or ellipsoidal morphology that appears to warp the older stratigraphy around it. In addition, there are correlating gravity highs that could indicate more mafic-ultramafic (denser) compositions.

FUTURE WORK PROGRAMS
The Company’s exploration focus is now on progressively air-core drill testing the selected targets. The initial drilling program will test the targets located north of the Trans-line Railway (Targets 1-5 in Figure 1 and 2). Drill hole positioning will be optimised by localised 3D inversion modelling of the magnetic/gravity data and joint compilation of the inversion outcomes.
The key aim of the drilling program is to confirm the presence of mafic intrusions, in particular, the intrusions with favourable litho-geochemical characteristics. If the drill program is successful in confirming a prospective intrusion, more detailed geophysical and drill programs will be undertaken, to determine if there are any economic concentrations of nickel sulphides hosted within the intrusion. The Company is in the process of selecting an appropriate drilling contractor and obtaining all necessary government approvals.

ABOUT THE FRASER RANGE TENEMENTS
In the Fraser Range, certain mafic intrusion suites are prospective to host nickel-copper sulphide mineralisation. The region is currently experiencing high levels of exploration activity for nickel following the Nova, Silver Knight and Mawson (formerly Area D) discoveries.
The Company’s tenements are located on the eastern margin of the northern Fraser Range gravity high and sit in between Legend Mining Limited’s (ASX: LEG) Mawson discovery and Galileo Mining Limited’s (ASX: GAL) Lantern Prospect. The tenements form part of the Company’s Orpheus Project which includes a 70% interest in E28/2403 by way of a joint venture with Enterprise Metals Limited (“Enterprise”) (ASX: ENT) and a 100% interest in E28/2738. Pursuant to the joint venture agreement between the Company and Enterprise, the Company is responsible for sole funding all joint venture activities on the tenements, which form part of the joint venture, up to completion of a bankable feasibility study.
Based on the processing and interpretation of the recent geophysical survey results, the Company has a made an application to the Department of Mines, Industry Regulation and Safety to acquire a further 6km[2] of prospective ground adjacent to E28/2403. As at the date of this announcement, the Company holds a 100% interest in application ELA28/2957.

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. |
No samples taken. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Magnetic surveylocations were measured with a Novatel L1/L2 OEM 719 DGPS receiver and altitude measurements were measured with a Renishaw ILM-500-R laser altimeter and an additional barometric sensor. Gravity surveylocations were measured with the Hi Target V100 GNSS DGPS system and post processed to achieve 5cm vertical and horizontal accuracy. GPS control points were established using the AUSPOS processing system. Approximately 6.5% of the gravity survey was repeated to provide a statistical analysis of the accuracy of the observed gravity data and GPS elevations. |

| 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. |
MAGNETIC SURVEY An airborne survey was conducted on 50m line spacing and 30m sensor height by MAGSPEC Airborne Surveys using a Cessna 210. The magnetic data was collected using a Geometrics GR823 caesium vapour tail sensor GRAVITY SURVEY A ground-based gravity survey was conducted on a 400m x 400m grid, with 200m x 200m infill over areas of interest. The gravity survey was completed by Atlas Geophysics Pty Ltd using Scintrex CG5 gravity meters with accuracies better than 0.01 mGal. Position and elevation data were acquired with the Hi Target V100 GNSS DGPS system operating in a post-processed mode to give horizontal and vertical accuracies better than 5cm.GPS control points were established using the AUSPOS processing system. Approximately 6.5% of the survey was repeated to provide a statistical analysis of the accuracy of the observed gravity data and GPS elevations. |

| 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 collaro elevation or RL (Reduced Level – elevation above sealevel in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole length. |
No drilling results reported. |
| 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. |
No drilling results reported. | |
| 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. |
No drilling results reported. |
| 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. |
No drilling results reported. | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values are used. | |
| Relationship between mineralisati on 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. |
No drilling results 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’). |
No drilling results reported. | |
| 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. |
Appropriate diagrams are included in the main body of this 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 Results. |
Reporting of the magnetic and gravity results is considered balanced. |
| 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 results; bulk density, groundwater, |
No additional meaningful and material exploration data has been excluded from this report. |
