ASX RELEASE 23 August 2021 ASX Code: COD
High-Grade Assays Confirm Bornite Zone at Emmie Bluff Deeps
High-grade copper and gold intercepts in DD21EB0018 wedge holes drilled to the southeast and west show strong grade improvement, indicative of a proximal mineralising structure.
Highlights
-
Outstanding assay results in two wedge holes drilled from parent hole DD21EB0018, confirm IOCG-style copper-gold mineralisation at Emmie Bluff Deeps:
-
Wedge 1: 17.1m @ 1.2% Cu, 0.3 g/t Au, 1.3g/t Ag from 824m
o Wedge 2 Upper: 24.0m @ 2.2% Cu, 0.3 g/t Au, 8.9g/t Ag from 815m;
Including:
-
3.0m @ 4.2% Cu, 0.3 g/t Au, 10.5 g/t Ag from 830m
-
Wedge 2 Lower: 12.9m @ 3.5% Cu, 0.6 g/t Au, 25.4 g/t Ag from 902m;
Including:
-
3.2m @ 4.9% Cu, 1.3 g/t Au, 41.8 g/t Ag from 905m and
-
2.9m @ 4.8% Cu, 0.3 g/t Au, 33.8 g/t Ag from 911m
-
Peak grades of 15.3% Cu and 4.49g/t Au in Wedge 2 (in the lower zone), and 3.37% Cu and 1.55g/t Au in Wedge 1 confirm potential for high copper and gold grades in the mineralised system.
-
The new assay data validate both field logging and Coda’s broader exploration model, providing strong directional evidence for the source of the mineralising fluids.
-
More than 35m of mineralisation grading in excess of 1% copper was intersected in parent hole DD21EB0018, with peak grades of 5.39% Cu within the higher-grade bornite zones and 1.19 g/t Au in the main chalcopyrite zone (See release on 28 July 2021).
-
Drilling is continuing with two new surface diamond drill holes to test mineralising structure well advanced with news flow expected in coming weeks.
-
Coda’s strong cash balance of ~$21 million underpins ongoing exploration.
Coda Minerals Limited (ASX: COD, “Coda”, or “the Company”), in conjunction with joint venture partner Torrens Mining Limited (ASX: TRN), a listed gold and copper company (“Torrens”), is pleased to report assays from drill-holes DD21EB0018W1 and DD21EB0018W2, both of which are “wedge” holes, drilled from positions at approximately 500m depth down the parent hole, DD21EB0018.

Assay results from copper sulphide mineralisation intersected by the parent hole were released to ASX on 28[th] July 2021[1] , These results included a best intersection of 28.1m at 1.21% Cu, 0.37g/t Au and 2.3g/t Ag from 810.8m , including 4.8m at 2.16% Cu, 0.63g/t Au and 4.3g/t Ag from 816.8m.
DD21EB0018, the first hole in the Company’s deep IOCG drill programme, was drilled to test the Emmie Bluff Deeps IOCG target, which forms part of Coda’s broader Elizabeth Creek Project in the heart of the Olympic Copper Province in South Australia (see Figure 5).
Coda is the operator and majority owner of the Elizabeth Creek Project, holding a 70% interest. Torrens holds the remaining 30% interest.
Summary of Results
The two wedge holes encountered copper-gold sulphide mineralisation broadly consistent with the previously released geological logs (see ASX release of 22 July 2021). A summary image is included as Figure 2 and the highest-grade intersections are as follows:
| Hole ID | From | To | Interval | Cu% | Au g/t | Ag g/t | Mo ppm |

Sections of diamond drill core which were considered to be most prospective were prioritised for rapid turnaround of processing and assaying. Further assays will be received in the coming weeks and may include minor additional mineralised intersections. Significantly, peak grades of 15.3% Cu and 4.49 g/t Au were encountered in Wedge 2 (in both cases in the lower mineralised zone), while peaks of 3.37% Cu and 1.55 g/t Au were encountered in Wedge 1.

Commenting on the assays, Coda’s CEO Chris Stevens said: “These exceptional results further refine and de-risk our exploration program. Building on the previously released assays from our first diamond hole, they give us further encouragement that we are closing-in on a large-scale IOCG deposit at Emmie Bluff Deeps. Wedge 2, in particular, is significantly more intensely mineralised than the parent hole, validating our exploration model. These are also the best-ever assays received from the Emmie Bluff IOCG prospect over many years of drilling by previous explorers.
“Our geological hypothesis is that these wedge holes have intersected more of the ‘apron’ of relatively flat-lying mineralisation that we believe surrounds a sub-vertical mineralising structure located close to DD21EB0018. These new assays demonstrate directionality through increasing copper grade and together with recent drilling data, assist in vectoring us toward a main mineralising structure.
“Our job now is to follow that vector with the drill rig and, in conjunction with ongoing geophysical work, to narrow down our target envelope. Our goal is to locate what we believe is a large, brecciated structure hosting high grade copper-gold mineralisation across a substantial vertical thickness. From that perspective, we are particularly excited by the lower borniterich zone encountered in Wedge 2. Around 90 vertical metres separates the top of the upper zone and the base of the lower zone in this hole. That width provides a strong indication that any mineralising structure that we encounter in the area will be at least that vertically extensive.
“Multiple drilling rigs are operating at Emmie Bluff Deeps, with two new surface drill-holes in progress and already well advanced, we anticipate further news flow over the next two to three weeks.”

Planned and Ongoing Work
Since the Company’s last major announcement on 28 July 2021 the Company drilled two holes to test the area to the northeast of the first parent hole. DD21EB0018W3 (i.e., Wedge 3) was drilled to the northeast of the parent hole DD21EB0018. DD21EBD0001 (Surface hole 2) was drilled commencing 470m to the north of the parent hole, terminating 350m to the north northeast of the parent hole. Both holes encountered complex structures and strong haematite alteration and are currently being prepared for assay. Data from these holes, particularly structural data, provides further refinement to the exploration model and assists in targeting further drilling that increases the potential of discovering significant mineralisation.
DD21EBD0001 was an especially challenging hole from a technical perspective and failed to reach the original planned proximity to the parent hole due in large part to the significant broken ground encountered associated with major faulting. In addition, loss of water return due to the encountered structures has effectively prevented wedging from this parent hole. This information, combined with the strong alteration intensity gradient and high-grade copper mineralisation encountered in Wedge 2 supports the current hypothesis that the mineralising structure is located to the southeast of existing drilling.
To that end, drilling is continuing with two surface holes currently in progress:
-
DD21EBD0002, a vertical drill-hole collared approximately 300m ESE of DD21EB0018; and
-
DD21EBD0003, an angled drill-hole, drilling at 80 degrees due north and collared approximately 300m south of DD21EB0018.
IOCG deposits in the Gawler Craton are often laterally constrained and, as such, these holes are designed to step out cautiously from known mineralisation, targeting vertical extension via mineralising structures. Both holes have been designed to allow maximum flexibility for additional wedge holes to be drilled based on results of each hole. The new surface holes are expected to reach target depth at approximately 250m east and 150m south respectively from the upper, bornite-rich mineralised zone in DD21EB0018W2 within 7 to 10 days.
Drill-hole locations are provided in the detailed map in Figure 3.
Assay Results in Detail
The assay results released here correlate very closely to the previously announced visually observed mineralised zones intersected by wedge holes DD21EB0018W1 and DD12EB0018W2 (see Figure 2). Preliminary interpretation of these results suggests a strong positive correlation between increasing copper and gold grades.
Mineralisation within DD21EB0018W1 is dominated by chalcopyrite, within a narrow 2.04m wide upper zone, and a lower 15.09m wide main zone. The main zone hosts the majority of the higher gold grades, with 7 of the 8 samples recording assays above 0.5g/t Au being located between 829m and 835.68m, including the peak grades of 0.62m at 0.75 g/t from 829m and 0.51m @ 0.75g/t Au from 835.17m.
Gold also generally shows moderate correlation with silver throughout, however the peak silver grade of 1.49m at 6.8g/t Ag was encountered at 820.56m down-hole, in the smaller upper chalcopyrite zone.
The mineralisation in DD21EB0018W2 occurs in two distinct zones. The upper mineralised zone is dominated by bornite and covellite and the lower mineralised zone is dominated by bornite, with the highest-grade assays reporting within the lower zone.
Peak gold assays of 0.4m @ 4.49g/t Au from 903.37m and 1.2m @ 1.12g/t Au from 904.56m occur within the lower mineralised zone, A total of 17 samples returned grades above 0.5g/t Au, with these samples associated with the margins of the upper mineralised zone and the core of the lower mineralised zone.
Radionuclides encountered so far at Emmie Bluff are low compared to other regional IOCG deposits, with peak uranium (U) and thorium (Th) grades of 90.5 ppm and 26.7ppm respectively in DD12EB0018W1, with average grades of 29.6 ppm U and

11.4 ppm Th through the mineralised chalcopyrite zone. DD12EB0018W2 returned peak uranium and thorium grades of 147ppm and 26.3ppm respectively, with slightly lower average grades of 37.9ppm U and 7.6ppm Th through the upper bornite-covellite mineralised zone, compared with average grades of 62.8ppm U and 9.0ppm Th in the lower bornite mineralised zone.
The continued low levels of radionuclides encountered at Emmie Bluff Deeps is considered to be a further positive for the Project, given the deleterious challenges typically faced by copper producers in dealing with these elements during mineral processing.
Anomalous Molybdenum (Mo) was identified by portable XRF during initial logging, and assays have subsequently identified areas of elevated Mo. While at the current early stage of exploration Coda does not believe it has encountered materially relevant molybdenum grades from an economic perspective, the Company will monitor Mo grades in future drilling and remains optimistic about the potential for further exploration for molybdenum.

Appendix 1: Assay Results
Assays disclosed in this reported are presented in the Table 1 (below) using a 0.3% Cu cut-off grade, which was determined based on comparison with nearby geologically comparable IOCG deposits and after considering current commodity prices. Given the strong correlation between copper and gold, and the lack of metallurgical testwork undertaken on the deposit, no attempt has been made to calculate a copper equivalent grade.
All elements which Coda believes have the potential to be economically relevant are included in the table below. Aggregated results may include internal dilution of no more than 1m of contiguous material below the 0.3% Cu cut-off grade.

|---|---|
| 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 • • • • • • |
Core was logged in the field and approximate metal content was measured at regular intervals with a portable XRF device at measurement intervals of between 1 and 0.5m. Sampling intervals were selected by field geologists based on logging and XRF results. Understanding of the mineralising system was based on historical drilling and the parent hole (DD21EB0018), as well as the XRF results, allowed large parts of the holes to remain unsampled. Typically, sampling is restricted to areas of strong hydrothermal alteration, particularly haematisation. The holes have been selectively sampled in order to rapidly send the parts of the hole with the most potential for copper mineralisation to the assay lab for rapid turnaround.

For this reason, Coda treats the results from the handheld XRF as indicative of the presence of metals only and has chosen not to release the results as they are not considered sufficiently accurate and may mislead as to the true nature of the intersected material. Coda’s field personnel prepared the core from DD21EB0018 for transport to Adelaide, where it was cut and sampled for assay by Challenger Geological Services. Portable XRF readings were taken in the field using an Olympus Vanta M tool applied directly to the core at either single or half metre intervals, depending on prior results or visual identification of potentialgrade bythe fieldgeologist.

| 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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
• Assays of drill core from hole DD21EB0018W1 and DD21EB0018W2 were undertaken by Bureau Veritas in Adelaide SA. • Halved core was crushed, split and pulverised before being digested and refluxed with a mixture of nitric, perchloric, hydrofluoric and hydrochloric acids. This extended digest approximates a total digest in most samples. • Most elements were determined by ICP-OES and ICP-MS, depending on accuracy required. The exception was Au, which was determined by fire assay. • These techniques were determined in consultation with the assay laboratory and are consider appropriate for the deposit type. • Field duplicates and standards were inserted at a 1:20 and a 1:10 ratio respectively (14 standards, 7 field duplicates over 133 total samples). • Average absolute error for target elements was 153.2 ppm Cu, 12.3 ppm Co, 0.039 ppm Au, 0.057 ppm Ag, and 3.5 ppm Mo. Insufficient sample (I.S.) was reported where insufficient sample was available to provide sufficient analyte for the laboratory to analyse for gold.

Data • In reporting Exploration Results, weighting aggregation averaging techniques, maximum and/or minimum methods 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.
-
The assumptions used for any reporting of metal equivalent values should be clearly stated.
| • | • | Significant intercepts are reported using a 0.3% Cu cut-off grade. Calculations of these | |
|---|---|---|---|
| intervals take the length weighted average of the assay results using a 0.3% Cu lower | |||
| cut-off grade and allowing no more than 1m of contiguous material of below the 0.3% | |||
| • | Cu cut-off grade as internal dilution. Where <1m of unmineralized (sub-0.3% Cu) material separates <1m of mineralised (i.e. |
||
| > 0.3% Cu) material at the top or bottom of a larger mineralised intercept, this material is excluded from aggregation and is reported separately. |
|||
| • | Selection of the 0.3% Cu value as a cut-off grade was determined based on comparison | ||
| with nearby geologically comparable deposits and after considering current | |||
| commodity prices. Given the strong correlation between copper and gold, and the lack | |||
| of metallurgical test work undertaken on the deposit, no attempt has been made to | |||
| calculate a copper equivalent grade. | |||
| • | Typical example of an aggregate intercept is included below: | ||

| 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’). |
• To date, Coda does not believe that it has sufficient data to comment on the orientation of major structures or the overall trend of the mineralisation at Emmie Bluff Deeps, nor the relationship between those features and the orientation of drilling to date, beyond the hypotheses put forward in graphics and text in the body of the announcement, which remain speculative until further drilling can be completed. • It is anticipated that further drilling will assist in clarifying these questions and will allow Coda to comment on their materiality. |
|||||||
| 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. |
• See map, sections and tables in main body of announcement. |
|||||||
| 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. |
• Coda has provided a detailed description of the material encountered and, where available, provided representative photographs of relevant mineralisation. • All assays >0.3% Cu are reported in this announcement. Intersects not specifically reported on in this announcement can be assumed to be <0.3% Cu. • Coda believes that this announcement represents an accurate and balanced reporting of the information it has to date. More information will be made available to the market as soon as practical upon its receipt by the company. |
