Latest Assay Results Confirm Extent, Grade and Continuity of Copper-Cobalt Mineralisation at Emmie Bluff
Results from latest two holes of 17-hole diamond drill program continue to support objective of delivering a Maiden Mineral Resource Estimate in Q3 2021
Highlights
-
Latest assay results continue to strongly validate the Emmie Bluff Exploration Target[1] , demonstrating increased thicknesses of mineralisation on the eastern side
-
Every hole drilled within the defined Exploration Target area has encountered significant coppercobalt mineralisation
-
New intercept of 7.58m @ 1.51% CuEq[1] demonstrates potential for thick intersections on the eastern side of the embayment, with widths such as this previously only seen on the western side

-
Coda has a current cash balance of +$10 million, with the Company fully funded to complete the Mineral Resource estimation process
Coda Minerals Limited (ASX:COD, “Coda” or “the Company”) is pleased to announce assay results from two drill holes that were undertaken during its recently completed 17-hole diamond drill programme at the Emmie Bluff prospect, part of its Elizabeth Creek Copper-Cobalt Project in the heart of the Olympic Copper Province in South Australia (See Figure 1).
Coda is the operator and majority owner of the Elizabeth Creek Project, holding a 70% interest alongside Torrens Mining (ASX: TRN), which holds a 30% interest.
The new assay results, from holes DD21EB0008 and DD21EB0009, include the following significant intercepts at a 0.3% copper equivalent (CuEq) cut-off:
-
DD21EB0008: 3.56m @ 1.07% CuEq (0.64% Cu, 360ppm Co, 9.2g/t Ag) from 419.19m including
o1.83m @ 1.74% CuEq [2] (1% Cu, 615ppm Co, 10.3g/t Ag) from 419.96m (0.5% CuEq cutoff). -
DD21EB0009 : 7.58m @ 1.51% CuEq (0.84% Cu, 558ppm Co, 8.1g/t Ag) from 440.63m, including
o3.77m @ 2.1% CuEq (1.16% Cu, 784ppm Co, 13.8g/t Ag) from 440.63m (0.5% CuEq cutoff).o1.02m @ 1.26% CuEq (0.91% Cu, 302ppm Co, 6.9g/t Ag) from 444.74m (0.5% CuEq cutoff).o0.44m @ 2.63% CuEq (0.92% Cu, 1420ppm Co, 2.6g/t Ag) from 447.77m (0.5% CuEq cutoff).

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. These two horizons can merge into a single lode as the host rock thins out at the edges of the basin, as exhibited in the thickened mineralisation in hole DD21EB0009 (7.58m @ 1.51% CuEq from 440.63m). This is considered particularly significant, as it demonstrates that thick intersections associated with the fringes of the embayment continue into the eastern side of the deposit. This implies a strong potential to optimise grade/tonnage trade off based on possible mining methods in a potential future resource. These opportunities will be followed-up in a mining study expected to be completed in Q2 2021
These results, together with the results previously announced[3] , continue to strongly validate the Emmie Bluff Exploration Target and support the Company’s goal of completing a maiden JORC 2012 Mineral Resource Estimate 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 to reduce this uncertainty and intends to deliver a JORC 2012 Compliant Mineral Resource Estimate in Q3 2021.
The Emmie Bluff copper-cobalt mineralisation remains open, especially to the south-east where strong potential for subbasins and associated satellite deposits has been identified. Work to fully evaluate this area is ongoing. Coda has recently commissioned a study into the structural geology of Emmie Bluff to help explain the better-than-expected thicknesses and grades on the eastern side of the deposit.
Coda CEO Chris Stevens said: “ These results, particularly those from hole DD21EB0009, have exceeded our expectations based on our preliminary logging, confirming strong continuity of grade and delivering surprising upside in terms of width for the mineralised body, particularly on the eastern side of the embayment.
“These results confirm the robustness of our Exploration Target and bring us closer to our short-term goal of delivering a Maiden Mineral Resource Estimate for Emmie Bluff in Q3 of this year.
“We are looking forward to receiving the balance of assay results from the remaining holes, currently in the laboratory, which are also expected to contribute towards recently commenced resource estimation work.”

The Emmie Bluff Exploration Target
The Emmie Bluff Exploration Target was first defined in 2019, and most recently updated in 2020.[4] 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, except where otherwise stated to be 0.3% CuEq. 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: DD20EB0008:1.83m @ 1.74% CuEq (1% Cu, 615ppm Co, 10.3g/t Ag) from 19.96m.

| 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. |
