IOCG Assays Extend Bornite Zone at Emmie Bluff Deeps
ASX RELEASE 22 December 2021 ASX Code: COD
Highlights
-
The next round of assays for the Emmie Bluff Deeps IOCG project have been received from the assay lab, with exceptional intersections from drillhole EBD3W2 in particular.
-
Highlights include:
-
Hole 3W2 has returned a mineralised intercept of 68m, comprising:
-
26.9m @ 1.95% Cu, 0.29 g/t Au from 803.5m, including 8m @ 3.55% Cu, 0.2 g/t Au from 816m and;
-
41.8m @ 1.21% Cu and 0.28 g/t Au from 911.5m
-
-
Hole 2W1: 18.5m @ 1.01% Cu, 0.24 g/t Au from 889.8m
-
• Hole 3: 13.3m @ 1.00% Cu, 0.23 g/t Au from 906.7m
-
Peak grades of 9.48% Cu in 3W2 support the company’s exploration model seeking extensions of this high grade bornite core, which is targeted for extension by drillhole EBD4 (currently being drilled).
-
Drilling will continue in the New Year as Coda continues to search for horizontal and vertical extensions of this high grade and potentially vast IOCG system.
-
Coda’s cash balance remains above $14 million at the date of this announcement.

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 the next round of assay results from drilling at its Emmie Bluff Deeps IOCG prospect.
Coda is the operator and majority owner of the Elizabeth Creek Project, holding a 70% interest alongside Torrens, which holds a 30% interest. Coda has an irrevocable option to acquire an additional 5% of the Elizabeth Creek Copper Project by paying $ 1.5 million to Torrens at any point from the current time up to 60 days from a decision to mine.
Assay results have been received for four holes for which visual estimates were released in October 2021; two parent holes DD21EBD0002 (EBD2) , DD21EBD0003 (EBD3) and two wedge holes DD21EBD0002W1 (2W1) and DD21EBD0003W2 (3W2) . Sections of diamond drill core which were considered to be most prospective were prioritised for rapid turnaround of processing and assaying. Additional assays from less prospective parts of the holes, as well as from the thick, low‐intensity disseminated and blebby chalcopyrite zones in the basement granite from holes 2W1 and 2W2 are expected in coming weeks. Further holes are either still being processed or are pending results from the assay lab (see table 2 below).
The most significant results came from 3W2, a wedge hole drilled to the northeast from EBD3, which was collared approximately 300m due south of the Emmie Bluff Deeps discovery hole, DD21EB0018. This hole encountered a significant structure from approximately 794 to 810.5m, before entering into a 26m zone of bornite mineralisation from 804m to 830m. This was then followed by a second intersection of a 42m within the lower lode dominated by chalcopyrite from 911 to 953m[1] .
Commenting on the assays, Coda’s CEO Chris Stevens said: “Hole 3W2 is our best assayed drill intercept at Emmie Bluff Deeps to date. The aggregate result of 68 metres of high-grade copper-gold mineralisation comprising two intervals of 26m at 1.95% Cu and 42m at 1.2% Cu confirm previously released visual results and highlight the presence of a high-grade bornite zone within the deposit.
“Based on recent visual intercepts, we expect that drillhole 3W3B, currently pending assay results, will return a similarly positive and potentially thicker intercept of bornite in the higher-grade upper lode, confirming the increasing trend of thickness within this high-grade zone towards the south-east.
“Beyond hole 3W2, we are continuing to demonstrate the classic IOCG sulphide zonation within the deposit – with a bornite zone now confirmed by assays from holes EB18W2 and EBD3W2 and the broader chalcopyrite halo intercepted by multiple mineralised holes. With these assays, we have now confirmed the expected transition to a pyrite dominated suite in EBD2, which would typically signal the edge of the mineralisation in an IOCG deposit. However, thanks to recent drill successes from drillholes 2W3 and 2W4, we know, based on visuals, that some of our thickest chalcopyrite dominated copper mineralisation comes back to the east and the north of hole 2, and very likely to the south as well.
“It will be a major priority to follow up on these encouraging signs and the potential for an enormous increase in lateral extent around EBD2. We are also very excited about our new parent hole EBD4, which is targeting the most prospective area to date – the interpreted thickening trend of the high-grade bornite zone to the south-east of EBD3W3.
“As of Monday this week, our field crews have now demobilised for a brief but well-earned Christmas and New Year’s break. I would like to take this opportunity to thank all of the contractors, consultants and employees who have worked so hard for us this year and look forward to recommencing fieldwork in the first week of January as we progress this exciting and growing IOCG discovery.”

Planned and Ongoing Work
Coda is currently progressing with two new parent holes, seeking an extension to the bornite dominated mineralisation encountered in drillholes 18W2, 3W2 and 3W3B and an understanding of the western extent of the chalcopyrite mineralisation which surrounds it.
EBD4: Located approximately 330m due east of EBD3, and drilled to the southwest, this hole is designed to continue to extend the mineralisation encountered in EBD3W2 and EBD3W3B. If successful, this will add an additional approximately 250m of strike to the known bornite mineralisation. Additional wedge holes EBD4W1 and EBD4W2 are also anticipated. Decision to drill these wedges will be dependent on results from parent hole EBD4.
EBD5: Located approximately 340m northwest of DD21EB0018, and drilled to the south, this hole is designed test the continuity of mineralisation encountered in 18W1 to the west, and attempt to extent that mineralisation to the edge of the gravity anomaly associated with Emmie Bluff Deeps. The anticipated pierce point for the mineralisation is just over 200m due west of 18W1, and will represent a material increase in the known mineralised envelope. An additional wedge hole, drilled to the southeast, is also anticipated.

Assay Results in Detail
The assay results released here correlate well with the previously announced visually observed mineralised zones. The overall interpretation of the deposit by Coda’s technical team remains a laterally zoned sediment‐hosted expression of an otherwise typical Gawler Craton IOCG‐type fluid, with mineralisation controlled by structural upgrading of a primary low Cu magnetite deposit and (likely) the sedimentary properties (particularly permeability and porosity) of the host rocks.
Mineralisation within EBD2 is dominated by pyrite, with minor disseminated chalcopyrite making up anomalous copper zones which stretch from 876m to 932m (averaging approximately 0.17% Cu and 0,03 g/t Au). Bands of higher‐grade chalcopyrite dominated mineralisation result in narrow reportable (i.e. >0.3% Cu) zones, typically <2m thick and spread throughout the anomalous interval.
This contrasts with hole EBD2W1 , which was drilled to the west‐southwest of EBD2. Anomalous copper results and chalcopyrite dominated mineralisation were encountered higher up the hole than in the parent hole but were largely restricted to narrow bands (which may be stratigraphically equivalent to similar mineralised bands at similar RLs in the parent hole).
At the main mineralised zone (19.46m @ 1.06% Cu from 889.78m), the hole achieved a separation from the parent hole of only approximately 50m, but the tenor and mineralogy of the mineralisation changed markedly, with significantly more chalcopyrite and less pyrite, and an overall higher Cu grade. Immediately below this mineralisation, mafic intrusives were noted which were not present in the parent hole. These intrusives may have overprinted or prevented the formation of a second mineralised horizon, which was observed from approximately 922m in the parent hole and 930m in wedge hole EBD2W2[3] (35m further west, not yet assayed)
2 Granitic basement assays still pending.

Both EBD2 and EBD2W1 should be considered in the context of the recently announced EBD2W4, which was drilled to the east‐southeast of the parent hole and encountered a thick sequence of chalcopyrite and patches of highly anomalous molybdenite[4] . Interpreted together, these holes suggest that EBD2 may represent something of a local nadir in mineralisation intensity, being too far from the major north‐northwest trending structure encountered in drillholes EDB3W2 and EBD3W3B for significant influence, as well as from the source of the mineralisation in 2W4, which is presumed to be a fault or splay further to the east. It is anticipated that further drilling in the area around EBD2W4 may identify this inferred structure along with additional associated mineralisation.
The assays in EBD3W2 were largely as expected, with strong copper grades over two stacked lodes for a combined total of approximately 68.5 mineralised metres. Stronger copper grades in the upper lode reflect the dominance of bornite in that lode vs chalcopyrite in the lower. Similarly, assays in EBD3 largely met expectations, though interestingly, while the copper mineralisation was largely restricted to an approximate 17m band of bornite dominated mineralisation from approximately 903 to 920m, gold anomalism extended considerably further above and below that band, expressed as an approximately 38m thick band from 896m at an average gold grade of 0.27 g/t (comparable to other mineralised intersections at Emmie Bluff Deeps). This is intriguing, as it strongly suggests that gold bearing fluids at least passed through the sedimentary host rock in considerable volumes, but either these fluids were not copper bearing (which fits with petrological evidence for multiple fluid flow events with different chemistries) or that conditions were highly variable on a local scale and promoted the precipitation of copper sulphides in some parts but not others.
Radionuclides at Emmie Bluff continue to assay low compared to other IOCG deposits in the Gawler craton. Molybdenum (Mo) grades continue to be anomalous having been first identified as such via portable XRF logging in the field.
Molybdenum is weakly correlated with copper, and recent results (not yet assayed) from drillhole 2W4 strongly suggest the mineralisation has a molybdenum rich component, at least in parts of the deposit. The Company will continue to monitor and report Mo grades in future drilling and remains optimistic about the potential for further exploration for molybdenum.

About Coda Minerals
Coda Minerals Limited (ASX: COD) is a minerals exploration company focused on the discovery, and development of base metals, precious metals, and battery minerals.
Coda is primed to unlock the value of its highly prospective Elizabeth Creek Copper Project, which is located in the heart of the Olympic Copper, Province Australia’s most productive copper belt.
The Elizabeth Creek Copper Project is centred 100km south of BHP’s Olympic Dam mine 15km from BHP’s Oak Dam West Project and 50 km west of OZ Minerals’ Carrapateena copper‐gold project. The project includes JORC 2012‐compliant Indicated Mineral Resources at the Windabout and MG14 deposits, which together host a combined 159,000 tonnes of contained copper and 9,500 tonnes of contained cobalt. The project also includes Coda’s recently estimated flagship Emmie Bluff Resource, which includes Indicated and Inferred components.
Coda has already commenced extensive exploration activities at Elizabeth Creek, which has earned the Company a majority interest in the project (70%). Coda holds the rights and interests to earn up to 75% interest in the project in Joint Venture with Torrens Mining Limited (ASX:TRN).
Coda has a dual strategy for success at Elizabeth Creek. Firstly, it is working to further define and extend known Zambian‐ style copper‐cobalt resources across multiple prospects, including Emmie Bluff, Powerline, MG14 North and Hannibal. Secondly, it is implementing a substantial drill programme at Emmie Bluff Deeps to evaluate the potential rapidly and efficiently for a Tier‐1 IOCG system following a major mineralised intercept in June 2021.
The company listed on the ASX in October 2020 after a successful, heavily oversubscribed IPO which is funding an aggressive exploration campaign across the Elizabeth Creek project tenure. Further information may be found at www.codaminerals.com

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 contiguous internal dilution splits a mineralised intersection, the |
||
| company may report “anomalous zones” which include the mineralised material and the internal dilution to better reflect realistic grades in a non‐selective or bulk mining |
|||
| scenario. | |||
| • | 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. | |||
| • | Intervals are rounded to the nearest 10cm for reporting purposes. | ||
| • | 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: | ||
| DD21EBD0003W2:26.9m @ 1.95% Cu, 0.29 g/t Au, 12.8 g/t Ag and 198 ppm Mo. | |||

| 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. |
