Wudinna Project Update

 

Initial Gold and Rare Earth Results

Significant zone of gold mineralisation defined at Clarke

REE mineralisation confirmed above gold mineralisation

 

Cobra, a gold exploration company focused on the Wudinna Gold Project in South Australia, announces initial gold results from the first five holes from the Company's recent 14 hole phase of Reverse Circulation ("RC") drilling on the Clarke prospect.

 

The Company has intersected a broad zone of mineralisation, confirming the orientation of mineralisation and demonstrating the potential for a significant gold mineral system at Clarke. Furthermore, re-analysis of previous samples defines a broad zone of elevated Rare Earth Elements ("REE") overlaying the intersected gold.

 

Highlights:

 

· CBRC0043 intersects 96m at 0.55 g/t gold from 30m including 20m at 1.5 g/t gold from 88m

 

· CBRC0042 intersects 19m at 0.79 g/t gold from 83m including 5m at 2.62 g/t gold from 95m

 

· Gold mineralisation is associated with diorite granitic alteration - the broad halo of mineralisation confirms the potential for a significant gold mineral system at Clarke

 

· Re-analysis of the saprolite horizon at Clarke within CBRC009 (which was drilled in 2020 and intersected 31m at 3.06 g/t gold from 69m) to test for Rare Earth Elements, defines:

 

20m at 550.5 ppm Total Rare Earth Oxides ("TREO") from 30m including:

8m at 874.8 ppm TREO from 31m

 

· The presence of elevated REEs within the saprolite zone, proximal to gold mineralisation, presents a complementary value-add opportunity to considerably increase the Company's mineral resources and improve development economics

 

· REEs are elevated in valuable 'magnet' elements'* and equate to 26% of the TREO within the reported intercept

 

· Results are pending for an additional nine holes totalling 1,372m from which mineral assemblages and alteration is consistent with the geology observed within holes CBRC0042 - 43. Both gold and REE results are expected over the next eight weeks

 

*Magnet rare earths are: Praseodymium, Neodymium, Terbium and Dysprosium

 

Rupert Verco, CEO of Cobra, commented:

 

"These encouraging preliminary results from Clarke confirm the potential for mineralisation. The broad halo of mineralisation demonstrates a potentially significant gold bearing system containing high-grade zones at relatively shallow depths. The Clarke prospect continues to deliver and has the potential to add to the Company's existing 211,000 Oz Mineral Resource Estimate. 

 

The presence of elevated Rare Earth Elements overlaying gold is quite literally icing on the cake and demonstrates a significant opportunity to complement the project's gold assets. Whilst we have work to do to determine the metallurgical properties of mineralisation, the confirmed spatial proximity to our gold assets has the potential to positively influence future project economics.

 

The remaining holes were designed to test the 1.1km Clarke gold anomaly, and geological observations are encouraging for further positive results. We look forward to providing further updates as results are received.

 

Our next steps in H1 2022 will be to quantify the gold resource potential at Clarke, define the extent and minerology of rare earth mineralisation across our existing gold resources, and continue with our next phase of exploration drilling to develop known gold and IOCG targets."

Interpretation of Results

 

Cobra's first phase of drilling (reverse circulation) was designed to test extensions to previously intersected gold mineralisation at the Clarke prospect, which is situated approximately 1.8km north of the 94K oz Mineral Resource Estimate of Baggy Green Deposit. A total of 14 holes were drilled totalling 2,144m testing northern and southern extensions. The results presented within this announcement represent 36% of the expected results. Multi-element and lanthanide analyses are outstanding for all drilled holes and gold results are outstanding for a further nine holes. The preliminary results confirm that:

 

· Scissored holes drilled directly north of drill hole CBRC0009 (intersecting 31m at 3.06 g/t) confirm a NW strike

· Mineralisation is associated with diorite intrusive alteration proximal to a major NW trending fault

· Higher grade staked lodes exist within a greater alteration halo

· Mineralisation is open to the north where additional drill holes have intersected zones of similar alteration

· A total of 150m of strike has been defined through the reported holes; a total of ~550m of strike will have been tested through the completion of this programme

· The southern fence of holes will test mineralisation continuity some 200m south of previously intersected mineralisation and follows up the 0.76 g/t Au identified within the pathfinder drilling programme

 

These results from Clarke define a significant zone of mineralisation and continue to support the potential for resource expansion through the ongoing definition drilling at Clarke. The broad widths of mineralisation and relatively shallow intersection depths justify further drilling.

Rare Earth Results

 

In follow-up to the elevated REE results identified within the recent pathfinder drilling programme, retained sample pulps from CBRC0009 were analysed for the 18 lanthanide elements. Results demonstrate elevated rare earths within the kaolinised portion of the weathered saprolite horizon. In response to these encouraging results Cobra will analyse all holes from the 2021 programme for lanthanides within the saprolite horizons.

 

The rare earths are considered to occur as Ion Absorbed Clay ("IAC") mineralisation. Further testing including XRD spectroscopy and HyLogger spectral analysis are underway to confirm REE mineralogy.

 

The zone of potential IAC Rare Earth mineralisation is considered significant with all holes from this programme intersecting similar saprolite profiles. Kaolinised clays are present at existing gold resources at Baggy Green, Barns and White Tank. Pending results from XRD spectroscopy, samples from previous drilling will be re-analysed to further evaluate the scale and potential for a Rare Earth resource to complement existing gold mineral resource estimates.

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 downhole 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.

· Sampling during Cobra Resources' 2021 RC drilling programme at the Clarke prospect was obtained through reverse circulation (RC) drilling methods.

· Historic RC and RAB drilling methods have been employed at Clarke and Baggy Green prospects since 2000. Rotary air-core drilling occurred earlier in 2021 and was used to aid in the programme design but have not been used for grade estimations or defining results that are reported in this announcement.

· Samples were collected via a Metzke cone splitter mounted to the cyclone. One metre samples were managed through chute and butterfly valve to produce a 2-4 kg sample. Samples were taken from the point of collar, but only samples from the commencement of saprolite were selected for analysis.

· Samples submitted to the Genalysis Intertek Laboratories, Adelaide and pulverised to produce the 50 g fire assay charge.

 

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).

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.

· Sample recovery was generally good with water being intersected in 10% of the drilled holes. All samples were recorded for sample type, quality and contamination potential and entered within a sample log.

· In general, sample recoveries were good with 35-50 kg for each one metre interval being recovered.

· No relationships between sample recovery and grade have been identified.  

Logging

· 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.

· This drilling programme has been carried out on EL 6131, currently owned 100% by Peninsula Resources limited, a wholly owned subsidiary of Andromeda Metals Limited.

· Newcrest Mining Limited retains a 1.5% NSR royalty over future mineral production from both licences.

· Aboriginal heritage surveys have been completed over the Baggy Green project area, with no sites located in the immediate vicinity.

· A Native Title Agreement is in place with the relevant Native Title party.

Exploration done by other parties

· Acknowledgment and appraisal of exploration by other parties.

On-ground exploration completed prior to Andromeda Metals' work was limited to 400 m spaced soil geochemistry completed by Newcrest Mining Limited over the Barns prospect.

· Other than the flying of regional airborne geophysics and coarse spaced ground gravity, there has been no recorded exploration in the vicinity of the Baggy Green deposit prior to Andromeda Metals' work.

Geology

· Deposit type, geological setting and style of mineralisation.

· The deposits are considered to be either lode gold or intrusion type mineralisation related to the 1590 Ma Hiltaba/GRV tectonothermal event.

· Gold mineralisation has a spatial association with mafic intrusions/granodiorite alteration and is associated with metasomatic alteration of host rocks.

· Rare earth minerals occur within the kaolinised saprolite horizon. Preliminary work supports IAC (Ion Adsorbed Clay) mineralisation. Further work is planned to define mineralogy and nature of mineral occurrence.

 

· 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 collar

o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

o dip and azimuth of the hole

o down hole length and interception depth

o hole 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.

· The report includes a tabulation of drill hole collar information and associated interval grades to allow an understanding of the results reported herein.  

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.

· Reported summary intercepts are weighted averages based on length.

· No maximum/minimum grade cuts have been applied.

· No metal equivalent values have been calculated.

· Rare earth element (REE) analysis was originally reported in elemental form and has been converted to relevant oxide concentrations in line with industry standards. Conversion factors tabulated below:

· The reporting of REE oxides is done so in accordance with industry standards with the following calculations applied:

TREO = La2O3 + CeO2 + Pr6O11 + Nd2O3 + Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + Y2O3

CREO = Nd2O3 + Eu2O3 + Tb4O7 + Dy2O3 + Y2O3

LREO = La2O3 + CeO2 + Pr6O11 + Nd2O3

HREO = Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + Y2O3

NdPr = Nd2O3 + Pr6O11

TREO-Ce = TREO - CeO2

% Nd = Nd2O3/ TREO

%Pr = Pr6O11/TREO

%Dy = Dy2O3/TREO

%HREO = HREO/TREO

%LREO = LREO/TREO

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 downhole lengths are reported, there should be a clear statement to this effect (eg 'downhole length, true width not known').

· This drilling programme is designed to confirm the orientation and continuity of mineralisation. Preliminary results support unbiased testing of mineralised structures.

· Previous holes drilled have been drilled in several orientations due to the unknown nature of mineralisation.

· The work completed to date is not considered robust to adequately define mineralisation geometry.

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.

· Plan and section maps are referenced that demonstrate results of interest.

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.

· Referenced Plans detail the extent of drilling and the locations of both high and low grades. Comprehensive results are reported.

 

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, geotechnical and rock characteristics; potential deleterious or contaminating substances.

· Significant intercepts of reported previous drilling is tabulated (CBRC0009).  

Further work

· The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).

· Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

· Further RC drilling is planned to test for both lateral and depth extensions. The complete results from this programme will form the foundation for a maiden resource estimation at Clarke.
