Dundee Precious Metals Inc. (TSX: DPM) (“DPM” or
“the Company”) is pleased to announce a maiden Mineral Resource
Estimate of 1.78 million ounces for its 100% owned Čoka Rakita gold
project in eastern Serbia, where DPM announced a high-grade
discovery in January 2023.
Highlights
- Strong maiden Mineral Resource estimate:
Inferred Mineral Resource estimate (“MRE”) of 9.79 million tonnes
(“Mt”) at a grade of 5.67 grams per tonne (“g/t”) for 1.78 million
ounces of gold. The maiden MRE was completed after only one full
year of drilling on the project and is based on approximately
80,723 metres of drilling in 173 holes.
- Higher-grade core of
mineralization: The MRE contains a significant portion of
gold ounces within a continuous high-grade core of mineralization
that amounts to 2.81 Mt at a grade of 10.12 g/t Au for 0.914
million ounces of gold. Once sufficient drilling has been completed
to upgrade the Mineral Resource confidence, this higher-grade core
has the potential to drive strong economics by accessing higher
than average grades during the early years of a mine plan.
- Upside exploration potential: DPM is
continuing its drilling program focused on extending the limits of
Čoka Rakita, which remains open to the northeast and to southwest,
and is also aggressively pursuing additional skarn targets on the
Čoka Rakita licence as well as on three additional licences to the
north and the south.
- Advancing to a preliminary economic assessment
(“PEA”): Based on the favourable size and quality of the
MRE, DPM will continue to accelerate the project and expects to
complete a PEA on the project in the second quarter of 2024,
targeting a throughput rate of 850,000 tonnes per annum.
- Attractive organic growth opportunity: Čoka
Rakita benefits from good infrastructure, including nearby existing
roads and power lines. The project is located in close regional
proximity to DPM’s existing operations in Bulgaria and is a strong
fit with the Company’s underground mining and processing expertise,
with metallurgical test work demonstrating gold recoveries of
approximately 90% by gravity concentration and conventional
flotation.
“The initial Mineral Resource estimate marks a
significant milestone for DPM’s future growth and confirms Čoka
Rakita’s potential as an attractive, high-quality gold project,”
said David Rae, President and Chief Executive Officer of Dundee
Precious Metals.
“Since we announced the initial discovery only
11 months ago, Čoka Rakita has rapidly grown into a 1.8 million
ounce deposit, a remarkable achievement over such a short period of
time, and we plan to continue aggressively exploring at Čoka Rakita
and the surrounding licences to generate new discoveries.
“We are continuing to accelerate the project
through our development pipeline, including advancing a PEA which
is targeted for completion in the second quarter of 2024. We are
excited by Čoka Rakita’s potential in a region where we have had a
presence for many years and where we have developed strong
relationships with local stakeholders.”
Maiden Mineral Resource Estimate
The Inferred MRE is comprised of 1.78 million
ounces of gold contained within 9.79 million tonnes grading 5.67
g/t Au (Table 1) and assumes an underground mining scenario.
Gold-rich skarn mineralization is hosted within
carbonate rich sandstones and conglomerates, located on the hanging
wall of a sill-like body and abutting a monzonite intrusive body to
the west. The mineralization forms a shallow-dipping tabular
mineralized body located between 250 and 450 metres below surface,
measuring 650 metres long, up to 350 metres wide, and with variable
thickness from less than 20 metres in the margins to more than 100
metres in the core of the mineralized zone. Coarse gold is often
observed in areas of intense retrograde skarn alternation and is
found mainly in proximity to syn-mineral diorites within the
higher-grade core of the deposit. The current MRE has been
conducted on the portion of the prospect where gold-rich skarn
mineralization occurs.
The drillhole database was handed over as of
November 16, 2023. A total of 173 drill holes totalling 80,723
metres were included in the estimation of the Mineral Resource. The
current drillhole spacing within the mineralized domains is
approximately 30 metres by 30 metres in the core of the system,
with an up to 60-metre by 60-metre grid on the periphery. Gold
grades within skarn domains have been determined systematically
using a screen fire assaying technique, which is preferred for
mineralization with coarse gold. Grade capping was applied to
composites to limit the influence of anomalously high-grade
values.
Mineral resource domains were created within
volumes of moderate to intense skarn alteration and guided by
economic composites at a 1 g/t Au cut-off value. Detailed lithology
and structural models were developed and used to constrain domain
extents, as well as to incorporate post-mineralization diorite
sills which cut across the mineralization. Block grade estimates
have been undertaken for Au, Ag, Cu, S and As using ordinary
kriging at a 10mE x 10mN x 10mZ parent block size with sub-celling
to honour domain volumes.
A break-even cut-off value of 2 g/t Au and a
minimum width constraint of 5 metres by 5 metres by 2.5 metres was
used to define optimized mineable shapes using Datamine’s Mineable
Shape Optimiser (“MSO”). These shapes were subsequently smoothed
and used to constrain continuous zones of mineralization for
reporting the final Mineral Resource statement.
The application of MSO shapes at the MRE stage
provides a robust estimate for the purposes of a PEA, and a higher
confidence in the potential for the conversion of Mineral Resources
into mineable tonnes and grades for the purposes of a mine plan for
the PEA. Mineral Resources that are not Mineral Reserves do not
have demonstrated economic viability. The MSO shapes have been used
to ensure Mineral Resources demonstrate reasonable prospects for
eventual economic extraction.
Material within the reporting MSO constraints
(smoothed) was classified as Inferred Mineral Resources according
to Mineral Resource confidence categories defined in the CIM
Definition Standards for Mineral Resources and Mineral Reserves.
Data quality and quantity, geological and grade continuity, and
confidence in the grade, density and reasonable prospects for
eventual economic extraction (“RPEEE”) criteria were considered
when classifying the MRE. Given the relatively continuous and
stratified mineralization style at Čoka Rakita, the Company has
reason to expect that the majority of Inferred Mineral Resources
could be upgraded to Indicated Mineral Resources with infill
drilling.

Mineral Resources are reported within smoothed MSO shapes generated
at a 2 g/t Au cutoff, to ensure Mineral Resources meet reasonable
prospects for eventual economic extraction. The smoothing process
allows for blocks below the cut-off to included within the final
shapes in order to emulate the internal dilution that would be
experienced during underground mining as per CIM Estimation of
Mineral Resources and Mineral Reserves Best Practices Guidelines
prepared by the CIM Mineral Resource & Mineral Reserve
Committee and adopted by the CIM Council on November 29, 2019. |

Higher-Grade Core of
Mineralization
Within the core of the Čoka Rakita deposit is a
zone of continuous higher-grade mineralization hosted within
intense retrograde skarn alteration. By digitizing an outline of
spatially contiguous blocks within the Mineral Resource that have
an estimated grade value higher than approximately 5 g/t Au and
including internal dilution, the block model reports 2.81 Mt at a
grade of 10.12 g/t Au for 0.914 million ounces of gold. Once
sufficient drilling has been completed to upgrade the Mineral
Resource confidence, this higher-grade core has the potential to
drive strong economics by accessing higher than average grades
during the early years of a mine plan.
When reported within the smoothed MSO
constraints used to report the MRE, the block model sensitivity to
cut-off grade is shown in Table 2. This table does not constitute a
Mineral Resource statement and is shown to illustrate the grade and
tonnage sensitivity to grade cut-off value.
Due to the presence of coarse gold and the
confidence level of Inferred Mineral Resources, there is inherent
uncertainty in the level of mining selectivity that can be achieved
as the cut-off grade is increased. Further drilling, and
potentially bulk sampling, is required to assess the short-range
grade continuity of the higher-grade mineralization.

Mineral Resources are reported within smoothed MSO shapes generated
at a 2 g/t Au cut-off, to ensure the mineral resources meet
reasonable prospects for eventual economic extraction. All blocks
that fall within that constraint are reported within the MRE.
Accordingly, the cut-off value of 0 g/t corresponds to the MRE
statement. |

Exploration Potential
DPM is planning an aggressive exploration
program for 2024 including:
- Approximately 30,000 metres of infill, hydrological and
geotechnical drilling, with the goal of re-classifying the current
Mineral Resource to the Indicated Mineral Resource category. This
also includes infill drilling to test the extents of Čoka Rakita,
which remains open to the northeast and to southwest; and
- 55,000 metres of additional exploration drilling at existing
skarn targets and to test for manto-like copper-gold skarn
identified across four licences held by DPM, including Čoka Rakita,
Potaj Čuka, Pešter Jug, and Umka.
Exploration and evaluation expenditures for the
above drilling programs, PEA and related technical work is expected
to be US$30 to US$35 million in 2024, which will be updated in
early Q1 2024 as part of the Company’s detailed 2024 guidance and
updated three-year outlook.
Attractive Organic Growth Opportunity
With a sizeable maiden MRE and significant
additional exploration potential, Čoka Rakita is an attractive
organic growth opportunity that DPM will be prioritizing for
advancement.
The project is located approximately 35
kilometres from the city of Bor in Serbia, is proximal to existing
roads and power lines and is approximately 320 kilometres northwest
of DPM’s Chelopech mine in Bulgaria which will allow easy access to
existing technical support functions. The project is a strong fit
with the Company’s underground mining and processing expertise,
with metallurgical testwork demonstrating gold recoveries of
approximately 90% by gravity concentration and conventional
flotation.
As previously reported on November 15, 2023,
metallurgical testwork confirmed the viability of a combined
gravity concentration and flotation circuit at different target
grades (Table 3).

Next Steps
In parallel to its exploration and infill
drilling activities, DPM has advanced activities to accelerate the
project, including initiating geotechnical and hydrogeological
drilling, the next phase of metallurgical testwork, evaluating
locations for potential site infrastructure, as well as stakeholder
engagement and permitting activities.
The Company has already commenced certain
scoping level activities and expects to complete a PEA on the
project in the second quarter of 2024, targeting a throughput rate
of 850,000 tonnes per annum.
The next phase of metallurgical testwork will
focus on the variability at Čoka Rakita to ascertain the
metallurgical and comminution performance of the different subtypes
of mineralization present, including testing on more copper-rich
areas of the prospect.
Permitting preparation activities are underway,
with good support and engagement from key regional and national
authorities.
Stakeholder Engagement
Consistent with its approach across all
operations and projects, DPM seeks to build and maintain strong
partnerships with local communities and governments. The Company
has had a local presence in Serbia since 2004 and has developed
strong relationships in the region and will continue to proactively
engage with all stakeholders as the project advances.
Planning for the project will be highly focused
on ensuring responsible environmental management and social
development in-line with industry best practices. DPM is committed
to working closely with local communities around the Čoka Rakita
project to understand and support local development opportunities,
with a focus on maximizing benefits of the project for Serbia.
