ASX Code: COD
Significant New Drilling Results Strengthen and Extend CopperCobalt Mineralisation at Emmie Bluff
New assays of up to 4.71% copper equivalent demonstrate potential to extend high-grade zones within the Exploration Target while also extending the overall mineralised footprint
Highlights
-
Final assay results received from Phase 2 of the Emmie Bluff drill programme
-
Drilling continues both to validate the Emmie Bluff Exploration Target[1] and extend the mineralised envelope to the north-east
-
Continuing the pattern seen in previous drilling, every hole drilled within the defined Exploration Target area has encountered significant copper-cobalt mineralisation
-
New intercept of 3m @ 4.71% CuEq[2] demonstrates potential to extend high-grade pods in the core of the Exploration Target
-
Phase 3, the final stage of drilling required to deliver a maiden JORC Mineral Resource, on track to commence in early May 2021
Coda Minerals Limited (ASX:COD, “Coda” or “the Company”) is pleased to report the final round of assay results from its two-phase, 17-hole diamond drill programme at the Emmie Bluff prospect, part of the Elizabeth Creek Project located in the Olympic Copper Province in South Australia (see Figure 1).
Emmie Bluff is an advanced shale-hosted Cu-Co-Ag prospect which forms part of Coda’s extensive portfolio of copper assets in this highly prospective region. Coda is the operator and majority owner of the Elizabeth Creek Project, holding a 70% interest alongside Torrens Mining (ASX: TRN) with 30%.
The most recent round of assays includes some of the highest-grade intercepts encountered at Emmie Bluff to date. The best assays from the most recent round include:
DD21EB0012: 2.24m[3] @ 3.19% CuEq (1.82% Cu, 1,139ppm Co and 24 g/t Ag) DD21EB0013: 3m @ 4.71% CuEq (2.85% Cu, 1,545ppm Co and 27 g/t Ag) DD21EB0014: 2.13m @ 3.53% CuEq (2.08% Cu, 1,212ppm Co and 28 g/t Ag)

The Cu-Co sulphide mineralisation at Emmie Bluff typically occurs on both the upper and lower contacts of the host Tapley Hill Formation black shale. The new assay results, from holes DD21EB0012, DD21EB0013 and DD21EB00014, include the following significant intercepts at a 0.5% copper equivalent (CuEq) cut-off (Table 1, below):
Table 1 – All mineralised intersections from holes DD21EB0008 and DD21EB0009, 0.5% CuEq cut-off.
| 0.5% CuEq Cut Off | |
|---|---|
| DD21EB0012 | 2.24m4@ 3.19% CuEq (1.82% Cu, 1,139ppm Co and 24 g/t Ag) from 497.11m. |
| DD21EB0012 | 0.83m4@ 0.64% CuEq (0.41% Cu, 195ppm Co and 7 g/t Ag) from 499.94m. |
| DD21EB0012 | 0.75m4@ 1.08% CuEq (0.5% Cu, 488ppm Co and 5 g/t Ag) from 501.08m. |
| DD21EB0013 | 3m @ 4.71% CuEq (2.85% Cu, 1,545ppm Co and 27 g/t Ag) from 400.47m. |
| DD21EB0013 | 2.31m @ 0.63% CuEq (0.48% Cu, 124ppm Co and 2985g/t Ag) from 441.3m. |
| DD21EB0014 | 2.13m @ 3.53% CuEq (2.08% Cu, 1,212ppm Co and 28 g/t Ag) from 445.25m. |
These new assays, together with previously announced results[6] , continue to strongly validate the Emmie Bluff Exploration Target and support the Company’s goal of completing a maiden JORC 2012 Mineral Resource Estimate for the deposit in Q3 2021.
The Emmie Bluff Exploration Target comprises 46 to 77 million tonnes at an estimated grade of between 0.5 and 2.3% CuEq (see Table 4 and its accompanying notes). The Exploration Target area stretches over 4.5 square kilometres and to date, every hole drilled within the defined Exploration Target area has encountered mineralisation. The Company notes that the potential grade and tonnage is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The Company is encouraged by results to date and is currently pursuing an aggressive exploration programme aimed at delivering a JORC 2012 Compliant Mineral Resource Estimate in Q3 2021.
Work continues to evaluate the potential for extensions to the mineralisation, especially to the south-east, where historical drilling has identified the presence of Tapley Hill Formation shale. Coda has commissioned a study into the structural geology of Emmie Bluff, which may assist in targeting future drilling in this area.
Coda CEO Chris Stevens said: “ The consistent drilling results generated within the Exploration Target area have further reinforced our confidence in the scale and robustness of the mineralisation at Emmie Bluff. In particular, the strong results from hole DD21EB0012 confirm the potential both to extend the mineralised envelope beyond the bounds of the Exploration Target and show the potential for excellent grades in these extensions.
“With our final assays now received, our focus is firmly on our third phase of drilling, which will commence next month – paving the way for a maiden Inferred Mineral Resource Estimate by late next quarter.”
4 Hole penetrated mineralised stratum at approximately 67°. True widths of intercepts are approximately 2.06m, 0.76m and 0.69m.
5 Results reported as per lab analysis. Assay result has been highlighted by QA/QC procedures and has been identified for reassay. See Table 1 for full details.

The Emmie Bluff Exploration Target
The Emmie Bluff Exploration Target was first defined in 2019, and most recently updated in 2020.[8] It consists of two layers of laterally extensive copper-cobalt-silver mineralisation at the upper and lower contacts of the Tapley Hill Formation black shale, with a combined tonnage of 46 to 77 million tonnes and an estimated grade of between 0.5 and 2.3% CuEq . The Company notes that the potential grade and tonnage is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

About Coda Minerals
Coda Minerals (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 covers 739 km[2] 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 2012compliant 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 Emmie Bluff prospect, which has a JORC compliant Zambian-style copper-cobalt Exploration Target, and strong IOCG potential.
Coda is the majority owner of the Elizabeth Creek Copper Project and operator of the Farm-in and Joint Venture with Torrens Mining (ASX: TRN), which currently owns 30% of the project. Coda holds the rights and interests to earn up to 75% interest in the project under the farm-in agreement with Torrens and anticipates completing its Farm-in expenditure commitment of a total project expenditure of $ 8.62 million by Q2 2021.
Coda has a dual strategy for success at Elizabeth Creek. Firstly, it is working to further define and extend known Zambianstyle copper-cobalt resources across multiple prospects, including Emmie Bluff, Powerline, MG14 North and Hannibal. Secondly, it is planning to systematically explore, define and where appropriate, drill-test copper-gold IOCG targets. Existing IOCG targets at Elizabeth Creek include Elaine, Elizabeth North, Chianti and also Emmie Bluff Deeps, which was recently redefined through extensive geophysical work.
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.

| 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. • • • |
Cut Off grade for reporting assays is 0.5% CuEq calculated as per Footnote 1 in the main body of the announcement. Due to the narrow nature of the mineralised intercepts, Coda believes that selective mining of high grade bands is likely impractical and would be misleading. All intersects have been reported as length weighted averages, in line with how they would most likely be eventually extracted. Typical example is included below: DD20EB00013:3m from 400.47m @ 4.71% CuEq (2.85% Cu, 1,545ppm Co and 27 g/t Ag).

| 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’). • • |
Due to drilling conditions, drillholes at Emmie Bluff are difficult to keep straight and tend to dip towards -90 degrees as they increase in depth, regardless of starting dip. The main mineralised stratum (Tapley Hill Fm shale) is relatively flat lying throughout the prospect area based on previously announced seismic results and historical drilling. As such, the near-vertical intersects reported are believed to be broadly representative of true width, except where otherwise noted (i.e. hole DD21EB0012). |
