CONFIRMATION OF EXPLORATION TARGET & MINERAL RESOURCE AND
ORE RESERVE STATEMENT
Coda Minerals Ltd (ASX code: COD) (Coda or the Company) provides the following statement
confirming details of its Emmie Bluff Exploration Target at its Elizabeth Creek Copper-Cobalt project
(Elizabeth Creek), which was originally issued by Gindalbie Metals on the 19th of June 2019, as well as
a statement of its Mineral Resource and Ore Reserve, including a summary of mining tenure held by
the Company.
EMMIE BLUFF EXPLORATION TARGET
Coda is currently engaged in a farm-in with Terrace Mining Pty Ltd (Terrace), a wholly owned subsidiary
of Torrens Mining Ltd (Torrens), to earn up to a 75% interest in Elizabeth Creek, located 135 km north
of Port Augusta in South Australia. The Company notes that the potential quantity and grade of the
Exploration Target is conceptual in nature, and that there has been insufficient exploration to estimate
a Mineral Resource. It is uncertain whether further exploration will result in the estimation of a Mineral
Resource.
Density data collected as part of the preparation for Coda’s seismic programme allow for a more
accurate estimate of the tonnage of the included mineralisation. The Exploration Target does not
currently reflect the results of that seismic programme as no drilling has been undertaken in the newly
identified areas of interest.
The updated Exploration Target headline figure is 46 – 77 MT @ 0.5 – 2.3 per cent CuEq, with full
details in
Table 1, below.
Table 1 Emmie Bluff Exploration Target. Tonnage range assumes a dry bulk density of 2.68 t/m3 with a range of +/25%. Grade range assumes length weighted average grades for Cu, Co and Ag with a range of +/-25%.

Planned Exploration to Test Exploration Target
Coda is currently preparing to undertake a major diamond drill programme at the Emmie Bluff prospect and expects to
commence drilling from November of 2020. The primary objectives of the program will be to expand the envelope of the
Exploration Target in line with recently released seismic data and to provide fresh drill core for geotechnical and
metallurgical analysis, as well as additional bulk density measurements.
About the Exploration Target
Data Inputs:
Drilling data used in generating the Exploration Target comprises publicly available drilling and assay results from the
South Australian Resources Information Gateway (SARIG) as well as 4 drill holes completed by Gindalbie in January 2019.
Tonnage Range:
The range in potential volumes of rock for the high and low side tonnage estimates of the Exploration Target are based
on geological modelling and drill hole assay results from historical and recent drilling.
An upper, higher-grade zone and smaller, lower grade zone (Figure 1 and Figure 3, below) have been modelled for the
stratabound Tapley Hill Formation. Hanging wall and Footwall surfaces for each zone were created and snapped to drill
holes with grades greater than 0.1% Cu or at geological boundaries (Whyalla Sandstone at hanging wall contact or
Pandurra Formation at footwall contact). The surfaces have been extended laterally to distances considered reasonable
for an exploration target in areas where the drill hole data supports this. In areas where it is clear from the drill hole data
that the surface does not continue, the surface is constrained. (e.g. Hole PEB64 – See Figure 2, below).
The modelled upper zone has a volume of 14,271,000 m 3 and the modelled bottom zone has a volume of 8,642,000 m 3.
To compute the tonnage range, a dry bulk density of 2.68 t/m 3 has been assumed in place of the value of 2.5 previously
assumed. This density was based on four holes which intersected Tapley Hill formation and which were recently measured
for bulk density. A summary of the depths and corresponding bulk density values within the shales are shown in Table 3.
The depths of the samples are from both mineralised and non-mineralised portions of the Tapley Hill Formation Shales.
Spatially, the four holes are located in the northern and western portion of the modelled mineralised domains (See Figure
1).
The continuous flat lying nature of the formation would suggest that similar bulk density values would be realized for the
southern and eastern portions and are considered to be a reasonable representation of the overall bulk density for the
purpose of revising the Exploration Target tonnage range.
A range of +/-25% has been applied to the results to estimate a Low Case and High Case as presented in Table 2, below.
Modelling is constrained to the north by the boundary of EL6265.

Formation. Details of sampling techniques are not known.
MODERN PROGRAM
• Samples were collected by HQ diamond drilling.
• Sampling intervals were determined based on geological logging and were at variable
intervals. Care was taken to separate lithologies, stratigraphy or structural features of
potential interest. Typical sample intervals in potentially mineralised areas was
approximately 30cm, likely non-mineralised samples were typically approximately 70cm.
Whole core was submitted for sampling, which was then sorted and crushed to 3mm before
splitting 300g of coarse material. The 300g split was then dried and pulverised in a vibrating
disc pulveriser. Samples were not dried prior to crushing so as to retain their chemical and
physical properties for metallurgical analysis. This resulted in a small risk of contamination
between crushed samples.
HISTORICAL
• Historical drilling techniques comprises Rotary – Percussion and Diamond Bit –
Coring. No reference to diamond diameter has been sighted.
• Length of Diamond tails where completed are detailed in Table 1 in the above
document.
• No core orientation data is available as all holes were drilled vertically.
MODERN PROGRAM
• Holes were precollared using a combination of mud rotary and percussion drilling.
• Diamond tails were drilled with HQ bits (63.5mm inside diameter.)
• Vertical holes were not oriented. Angled holes were oriented by Reflex ACT core orientation
tools.
HISTORICAL
• No specific reference to drill sample recovery, applicability or procedures were sighted in
any documentation referenced to the satisfaction of the Company.
• No correlation between core recovery and assay grades can be made in the absence of
sample recovery information.
MODERN PROGRAM
• Samples were not recovered from the precollars.
• Sample recovery from diamond drilling was assessed qualitatively by drillers and
field staff.
• Recovery and sample quality is considered to be very high.
• There is no observed correlation between core recovery and assay grades.

• Geological logs for both rotary percussion and diamond core for some of the historical
holes have been sighted. Descriptions include lithology, grain size, angularity, colour

• The Company has assumed that the verification of any significant intersection was
performed by suitably qualified personnel.
• No twin hole data is available.
• Handwritten assay results were sighted for some of the historical holes and where
available, validation and verification of transposing from physical to electronic copies
has been undertaken.
MODERN PROGRAM
• All reported data was subjected to validation and verification by Mr Craig Went, an
independent geologist contracted by the company and Mr Matthew Weber, an
employee of Coda, prior to release.
• Data was entered into standard file formats by Bureau Veritas and transmitted to the
company via email. Data has not been transcribed except electronically.
• Submitted standards are tabled and compared to the stated value. Acceptable
accuracy was achieved in the majority of cases.
This program included no twinned drill holes.
HISTORICAL
• Location of data point (collar Easting, Northing and RL) have been sourced through SARIG
and other company acquired data. Where required collar co-ordinates have been
converted, the GDA94, Zone 53 datum. Some small discrepancies of the collar coordinates and RL’s between company sourced data and SARIG data have been observed
but are not considered to be of material significance.
• Some collar RL’s were adjusted to match the digital elevation model.
• No down-hole survey data has been recorded as no angled holes were drilled.
MODERN PROGRAM
• The holes were planned using desktop GIS software and the GDA94, Zone 53 datum.
• Collar locations and elevations were determined by handheld GPS with an
approximate accuracy of +/-3m.
• Elevation data was compared with pre-existing digital elevation model and found to be

Exploration and reporting of historical drilling results was undertaken exclusively on EL
6265.
• EL 6265 is currently held 51:49 by Coda Minerals and Terrace Mining Ltd. Coda
Minerals is undertaking a farm-in joint venture to gain up to 70 percent ownership
over the tenement through expenditure of $6.62 million. Coda has the option to then
purchase an additional 5 per cent for $1.5 million, increasing its total potential
ownership to 75 per cent.
• Emmie Bluff has been previously drilled primarily by prior owners exploring for underlying
IOCG occurrences. This data has been made public by the South Australian Department of
Energy and Mining via the South Australian Resources Information Gateway (SARIG). Coda has
this information and a summary of the relevant drillholes are presented in Table 3 herein.
• The Elizabeth Creek project sits in the Stuart Shelf within the broader Olympic Copper
Province in South Australia. Specifically, mineralisation is hosted in the dolomitic shales
and dolarenites of the Neoproterozoic Tapley Hill Formation. This formation
unconformably overlies the Meso/Palaeoproterozoic Pandurra Formation due to local
uplifting associated with the Pernatty Upwarp. This unconformity, as well as structures
associated with the Pernatty Upwarp, represent the most likely fluid flow pathways
associated with the emplacement of metal bearing sulphides.
• Emmie Bluff mineralisation closely resembles mineralisation in the MG14 and Windabout
resources found approximately 40 kilometres to the south, also within the broader
Elizabeth Creek tenure.
