Excellent gold and copper recoveries at Ravensthorpe Gold Project

Highlights

  • Metallurgical testwork confirms high recoveries of gold and copper from conventional process routes

  • Gold recovery averages 95.9% and 92.5% for all historical gravity-flotation-leach and gravity-leach tests respectively

  • Copper recovery averages 73.0% for all historical flotation tests

  • GR Engineering Services Limited (“GRES”) engaged to review historical metallurgical testwork to confirm conventional process route for Ravensthorpe ore and to advise on further work required to support future Definitive Feasibility Study

  • Consolidation of the significant amount of historical testwork forms a key milestone for confirming technical and commercial viability of Ravensthorpe Gold Project

Medallion Metals Limited (ASX:MM8, the “Company” or “Medallion”) provides the following update in relation ongoing metallurgical studies at the Company’s flagship Ravensthorpe Gold Project (“RGP”).

Overview

Medallion has engaged GRES to undertake a comprehensive review of all historical metallurgical testwork undertaken on RGP ores. The cumulative results of all historical testwork conducted provides a substantial database upon which to conduct the GRES metallurgical review. The review will be tasked to confirm that an industry standard gravity/flotation/leaching process route is the preferred option to maximise gold and copper recovery from RGP high copper ores, with estimates of reagent consumptions, recoveries and concentrate grades expected under normal operating conditions. The review will also investigate the ability to bypass the flotation step for low copper ore. Additionally, a gap analysis will be undertaken to establish what additional metallurgical testwork is required to support a Definitive Feasibility Study (“DFS”) level of assessment of the technical and commercial viability of RGP in the future.

GRES’ long involvement with the design, construction and recent enhancement of the Deflector gold-copper process plant ensures it is well placed to advise the Company on process design and engineering given RGP is expected to share many of the same aspects of Deflector in terms of scale and configuration given the mineralogical similarities. The Company expects to report the findings of the GRES metallurgical review in December 2021.

Managing Director, Paul Bennett, commented:

“The metallurgy review is an important step for Medallion to both consolidate the significant amount of historical work done and plan for the future. Our intention is that the next round of metallurgical testwork is definitive and final such that it supports a definitive level of assessment of RGP. The historical results suggest high gold and copper recoveries can be consistently achieved using industry standard processes. This work will increase certainty that those results are repeatable across the lithologies and deposits and can be scaled up to commercial rates. We’re pleased to have an industry leader in GR Engineering assist us in this regard.”

Historical Testwork Summary

Three substantial phases of metallurgical testwork have been undertaken on RGP ores, the first in 2005, followed by more recent programmes in 2018 & 2019 (Table 1).

Testwork programme 2005 2018 2019
Laboratory Ammtec/IML/Optimet ALS Bureau Veritas
Aggregate sample 1,613kg 658kg 306kg

Table 1: Laboratory & sample mass submitted for historical RGP metallurgical testwork programmes

Drill holes sampled to form metallurgical testwork composites are shown in Figure 1, with collar details provided as Annexure 1. The samples are a representative spread across the lithologies and deposits that comprise the Company’s current JORC 2012 Mineral Resource Estimate (“MRE”) of 674,000 oz[1] .

The 2005 and 2018 programmes comprised analyses of sample mineralogy, comminution, gravity separation, whole ore cyanidation, flotation testing, cyanidation of flotation tails in addition to investigations into the properties of concentrates and tailings produced through the testwork. The 2019 programme was limited to whole ore cyanidation and tailings detoxification tests.

Following grind size optimisation work undertaken in the 2005 programme, P80 75µm was selected as optimum. The bulk of the 2005 testwork was undertaken at this particle size however a small number of tests were undertaken at P80 53µm and P80 106µm. All of the 2018 and 2019 tests were undertaken at P80 75µm.

Testwork was conducted in both site and Perth tap water. Average head assay data (gold and copper) for all sequential gravity-leach and gravity-flotation-leach test composites are summarised in Table 2.

Gravity-Leach Results

Gold recovery from the 85 sequential gravity-leach tests undertaken on RGP ore between 2005 and 2019 are summarised in Table 3. Results are reported after 48 hours of leaching. Lime and sodium cyanide (“NaCN”) consumption rates are also shown.

1 8.8 Mt @ 2.4 g/t Au (7.0 Mt @ 2.3 g/t Au Indicated and 1.8 Mt @ 2.6 g/t Au Inferred). Refer to the Company’s Prospectus announced on the ASX on 18 March 2021 for further details regarding the MRE, historical production and Competent Person’s Statement.

Table 3: Aggregate Gravity-Leach results

43 of the 85 tests are from samples derived from positions in the weathering profile above the top of fresh rock (“TOFR”). The presence of secondary copper minerals above the TOFR are in some cases soluble in NaCN and contribute to elevated NaCN consumption rates. A key focus of the GRES metallurgy review will be management of NaCN consumption rates as the mine plan transitions through the weathering profile and into fresh rock.

Gravity-Flotation-Leach Results

Total gold and copper recovery from the 43 sequential gravity-flotation-leach tests undertaken on RGP ore between 2005 and 2018 are summarised in Table 4. The majority of tests were undertaken on fresh samples with the exception of 4 samples of oxide ore which were tested under modified conditions using industry standard copper oxide sulphidisation regime to trial the recovery of copper to a saleable concentrate ahead of the leach of the flotation tails.

Au recovery Cu recovery
% %
Mean 95.9 73.2
Median 97.1 83.1
Max 95.5 97.7
Min 82.9 2.2

Table 4: Aggregate total gold and copper recovery from Gravity-Flotation-Leach testing

The average copper grade of concentrate produced through the flotation phase of the testing was 15.9%. The average mass pull into the concentrate was 4.9%.

Gold distribution to each phase of the gravity-flotation-leach testing is summarised in Table 5.

Gravity Flotation Leach Total
% % % %
Mean 39.3 36.7 20.9 95.9
Median 37.8 34.7 20.2 97.1
Max 76.3 66.0 55.1 100.0
Min 6.6 17.0 0.3 82.9

Table 5: Gold distribution for Gravity-Flotation-Leach tests

Lime and NaCN consumption rates for the leach phase of the testing are presented in Table 6.

Lime consumption NaCN consumption
kg/t kg/t
Mean 2.08 1.61
Median 1.41 1.30
Max 8.52 7.15
Min 0.60 0.03

Table 6: Aggregate total gold and copper recovery from Gravity-Flotation-Leach testing

The gravity-flotation-leach results demonstrate the potential advantage of that process route selection in that it offers the ability to deliver not only NaCN cost savings but also additional revenue from copper production.

completed a full database validation on the nature

determined that there is a lack of detailed
information available pertaining to the equipment
used, orientation methods, sample techniques,
sample sizes, sample preparation and assaying
methodologies utilised to generate these datasets.
Downhole surveying of the drilling where
documented has been undertaken using Eastman

Drilling completed during 1997 and 2016 at Kundip
was completed by Tectonic Resources (TTR) and
Silver Lake Resources (SLR), they followed
protocols and QAQC procedures as per industry
best practice at the time. Drill holes were sampled
using diamond core drill holes (DD), Reverse
Circulation (RCP), for a total of 1,784 drill holes for
114,156.50m. Drilling has been completed on
nominal spacing of 40m x 20m spacings.
Downhole surveying of the drilling where
documented has been undertaken using Eastman
single and REFLEX EZ-SHOT.

In 2017 Medallion completed 14 diamond core drill
holes for 1,945m. In 2018, Medallion completed
RCP (32 for 2,679.4m), DD (13 "tails" for
1,424.27m) and AC (77 for 3,745m). Diamond
core holes were drilled predominantly with HQ/NQ
with minor PQ. Sampling was geologically defined
and followed protocols and QAQC procedures as
per industry best practice. Downhole surveying of
the drilling has been undertaken using REFLEX
EZY-SHOT and north seeking gyro tool.

Historical sampling used half-core (BQ & NQ)
marked up for assay at a maximum interval of 1m
constrained by geological boundaries. Minimum
samples <30cm exist and there is a lack of
detailed information available pertaining to
equipment used and orientation methods for
structural analysis.

TTR - DD core (HQ & NQ) has been reconstructed
and orientated in an angle iron cradle and
structural readings obtained by either “Rocket
Launcher” or Kenometer Core Orientation tools,
logged geologically, and marked up for assay at a
maximum sample interval of 1m constrained by
geological boundaries. Drill core is sampled from
same side of core when cut in half by a diamond
core saw and half HQ and NQ core samples
submitted for assay analysis. All Diamond core is
stored in industry standard core trays and racks
and is labelled with the drill hole ID and core
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 to produce a 30 g
charge for fire assay’). In other cases, more
explanation may be required, such as where there
is coarse gold that has inherent sampling
problems. Unusual commodities or mineralisation
types (e.g., submarine nodules) may warrant
disclosure of detailed information.

intervals.

Medallion - DD were drilled with PQ, HQ and NQ.
All core is orientated, and structural readings
obtained using a Kenometer Core Orientation tool,
logged geologically, and marked up for assay at a
maximum sample interval of 1m constrained by
geological boundaries. Drill core is sampled from
same side of core when cut in half by a diamond
core saw and half PQ, HQ and NQ core samples
submitted for assay analysis. In intervals of un-
orientated core, the same half of the core has
been sampled where possible, by extending a cut
line from orientated intervals through into the un-
orientated intervals. The lack of a consistent
geological reference plane, (such as bedding or
foliation), precludes using geological features to
orient the core. All Diamond core is stored in
industry standard core trays and racks and is
labelled with the drill hole ID and core intervals and
have been reviewed by the Competent Person.

RCP, AC and RAB sampling methodology has
changed over time. Sample collection prior to
2007 was via a cyclone, dust collection system
and multi-stage riffle splitter attached to the drill
rig. From the beginning of 2008, sample collection
was via a cyclone, dust collection system and
cone splitter attached to the drill rig. Barren zones
were composite sampled (2-4m) with anomalous
zones re-split into 1m samples. RCP chips were
routinely collected in chip box trays at 1m intervals
where it was geologically logged, and sample
intervals determined. All chip box trays have been
reviewed by the Competent Person.

It is the Competent Person’s opinion that sample
representivity of drilling at Kundip is of a good
quality.

Historically drilling is a combination of RAB, AC,
Vacuum, RCP, DD, and underground DD. Details
for hole diameter and bit types for RAB, AC and
Vacuum drilling is generally unknown. Reverse
Circulation drilling has been utilised to an average
depth of 76m and as pre-collars to diamond core
holes. Reverse Circulation drilling has been via
face sampling hammer with a hole diameter
approximately 5 ½ inch. DD core diameter is
dominantly a combination of HQ3/NQ2 with limited
PQ.

Post 2003, diamond core was cut using a diamond
core saw and predominantly ½ core collected for
analysis. Minor ¼ core sampling has occurred in
selected DD holes that were used for metallurgical
test work.

In all TTR drill programmes (1997-2011), RCP
samples in mineralised zones were riffle split at
one-metre intervals. In barren zones spear
samples were collected at 2-4m composites from
the un-split portion of the sample using a 50mm
PVC spear. If elevated metal values were reported
from the composite samples the riffle split samples
from those intervals were subsequently submitted
for analysis.

On rare occasions when samples were wet, the
sample was collected by grab sampling by the site
geologist. All drilling and sampling were
completed under geological supervision.

For TTR/Medallion RCP drilling, samples were
split into 1m intervals directly off a rig-mounted
splitter into pre-numbered calico bags and green
bags. Samples were initially composite sampled
on a two to four-metre basis using a 50mm PVC
spear, whilst mineralised intervals were sampled
on a 1m basis from the green bags and if they
were anomalous in gold or copper, the 1m calico
bag was submitted. Sample weights were typically
2 - 3 kg with minor samples >3 kg. Collected
sample bags were placed in labelled and
numbered plastic and/or polyweave bags for
dispatch to assaylaboratory.

Element suite included, Au, Ag, Cu (±As, Co, Fe,
Mn, Pb, S, Zn). It is unknown what analytical
techniques were used before 2003. From 2003
onwards (when earliest metallurgical testwork
samples were collected), analysis involved using
a four-acid digest with a 50g fire assay (FA) aliquot
for gold and Atomic Absorption Spectrometry
(AAS) finish for all elements. The acids used are
hydrofluoric, nitric, perchloric and hydrochloric
acids, suitable for silica-based samples.

In 2011, AC and RCP samples were sent to Aurum
Laboratory in Perth and were analysed by Aqua
Regia for Au (AUAR50), Ag and Cu (AUARBM).
Samples with Au values greater than 0.2ppm were
subsequently analysed using 50g fire assay and
Cu and Ag by AAS.

In 2017, Medallion samples were submitted to
ALS Laboratory in Perth. Element suite included
Au, Ag, Cu, Fe and cyanide soluble Cu. Analytical
techniques used a four-acid digest multi-element
suite with fire assay and AAS finish for Au (50g)
and inductively coupled plasma atomic emission
spectroscopy (ICP/AES) finish for additional
metals. Cyanide soluble Cu levels were analysed
using a cyanide leach. The acids used are
hydrofluoric, nitric, perchloric and hydrochloric
acids, suitable for silica-based samples.

Medallion also re-submitted 860 historic pulps
from 2009-2010 TTR drilling to SGS for analysis
of cyanide soluble Cu levels. Historic samples for
drilling prior to 2003 have unknown laboratory
procedures with Au analysed by fire assay with
nominal AAS finish. Varying levels of Cu and Ag
have also been analysed.

In 2018 Medallion samples were submitted to SGS
Laboratory in Perth for a 29 element suite.
Samples underwent a four-acid digest with fire
assay and AAS finish for Au (50g), ICP/OES finish
for Al, Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P,
Pb, S, Th, Ti, V, Zn and ICP-MS for Ag, As, Bi, Rb,
Sc, Sr, Te, Tl, W, Zr. The acids used are
hydrofluoric, nitric, perchloric and hydrochloric
acids, suitable for silica-based samples.

Standard chemical analyses were used for grade
determination. There was no reliance on
determination of analysis by geophysical tools.

Internal Checks every 1:20 to check original pulp
for analytical precision, laboratory repeats on a
second pulp split to measure assay variability –
typically on samples assaying greater than a
specified value, and internal Laboratory Standards
to measure analytical precision. A Maxwell
Geoservices QAQCR report for copper and gold
found no glaring concerns, although laboratory
repeats on higher grade gold samples (typically >
10ppm or 10 g/t Au) exhibit far more scatter than
the internal laboratory checks. This is to be
expected as lab repeats are generally performed
on results assaying higher than a specified value
which may contain nuggetty or spotty gold.

Between 2004-June 2010, QC procedures
included the insertion of certified standards,
blanks, and field duplicates. An external review of
the database was competed by Cube Consulting
in 2010 who reported that based on the limited
data available, approximately 11% of QAQC
control standards returned values outside the
accepted limits for assessing the accuracy of the
data. The majority of these erroneous samples are
from copper analysis of uncertified blanks, where
the assay values and standard deviations are not
accurately known. The certified standards show
that 8% of the samples exceed three (3) standard
deviations but overall, no significant bias was
detected that may indicate a material issue with
the primary assays.

In 2015 a total of 26 field duplicates were inserted
at a rate of 1:21 with standards and blanks
randomly inserted (every 1:24 and 1:41 samples
respectively). No concerns were identified with the
CRM’s. Field duplicates were analysed for gold
and copper. The gold values of duplicates showed
poor repeatability with 15 outside the 10%
accepted
limits.
Copper
showed
good
repeatability with 80% of the repeats within 25% or
less of the original value. As only gold repeatability
was poor it is presumed that samples may contain
nuggety or spotty gold.

In 2017, Medallion submitted certified standards
(4.1%) and blanks (3.6%) with duplicates (3.5%)
rotary split from 2mm fine Boyd crusher at the
laboratory. 3 blanks inserted after high-grade (>20
g/t Au) material showed contamination with no
other bias detected that may indicate a material
issue with the primary assays.

In 2018, Medallion submitted certified standards
(4.3%) and blanks (1%) with field duplicates
selected from Resource Definition RCP and DD
(1.3%). 90% of field duplicates consisted of ¼ core
samples very closely adjacent to the original
quarter-core sample. The remaining samples
were RCP riffle splits from the original RCP rig
cone splitter reject. Duplicate repeats on higher
grade gold samples (typically > 5ppm or 5 g/t Au)
exhibit far more scatter than the lower grade
samples which displayed good repeatability.
Copper and silver repeats display excellent

A Trimble RTX GPS was used between 2002-
2007 to pick up collars. Accuracy is ±5cm for
easting, northing and elevation.

Drill hole collars between 2007-2010 were picked
up using a DGPS. Accuracy is ±1m for easting,
northing and elevation.

Between 1996 - 2011, all downhole surveys were
completed with either an Eastman single-shot
camera or Reflex EZ-SHOT on nominal 30m
intervals. A minor percentage of the drill holes
have deviation from the initial azimuth which is
believed to be the effects of pyrrhotite within
massive sulphides within the ore zone. The
reliability of the historical downhole surveying is
considered average. In 2015, SLR completed

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
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 drillhole 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’).

Not
relevant
to
samples
collected
for
metallurgical testwork.
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 the drillhole collar
locations and appropriate sectional views.

Not
relevant
to
samples
collected
for
metallurgical testwork.
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.

Due to the large number of results, mean,
median, maximum and minimum values are
presented for each key area of reporting.

No comment is made as to the ability to replicate
the results at scale in an operational setting.

The report is considered balanced and in context.
Other
substantive
exploration
data
Other exploration data, if meaningful and
material, should be reported including (but not
limited
to):
geological
observations;
geophysical survey results; geochemical
survey results; bulk samples – size and method
of treatment; metallurgical test results; bulk
density, groundwater, geotechnical and rock
characteristics;
potential
deleterious
or
contaminating substances.

Not
relevant
to
samples
collected
for
metallurgical testwork.
Further work The nature and scale of planned further work
(e.g., tests for lateral extensions or depth
extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of
possible extensions, including the main
geological interpretations and future drilling
areas, provided this information is not
commercially sensitive.

Medallion is in the process of conducting a
30,000m RCP and DD drill programme at RGP
during 2021. Drilling is primarily for resource
extension and definition purposes however
remnant sample will be preserved for future
metallurgical testwork.

Additional metallurgical testwork is expected to
be undertaken in 2022 for definitive feasibility
study level assessment of the Ravensthorpe
Gold Project.
