Dundee Precious Metals Inc. (TSX: DPM) (“DPM” or
“the Company”) today reported wide intercepts from drilling at the
copper-gold-silver Dumitru Potok prospect, located on the Čoka
Rakita exploration licence. Based on these strong results, DPM is
accelerating its systematic target delineation drilling campaign at
Dumitru Potok to further extend these high-grade zones. The Company
also reported additional results from Rakita North and early
results from the new Valja Saka target, which are located on the
Čoka Rakita and Potaj Čuka licences, respectively. All three
prospects are located near planned Čoka Rakita project
infrastructure.

Dumitru Potok prospect: Recent drilling confirms
the presence of a large, high-grade copper-gold-silver skarn system
with mineralization concentrated along both the eastern and western
sides of a causative intrusion. Based on drilling to date,
mineralization has been detected over a one-kilometre strike
length, up to 300 metres vertically and up to 500 metres away from
the causative intrusion. The Dumitru Potok prospect is
characterised by long intercepts of continuous high-grade
mineralization that currently remains open in multiple
directions.
-
Rakita North prospect: New drill results from the
Rakita North prospect confirm presence of significant marble-hosted
copper-gold-silver mineralization on the northern flank of the Čoka
Rakita deposit. This is best demonstrated by drillhole RADD050,
which is proximal to the Čoka Rakita planned underground
development (see Figure 3). These drill results confirm a
relatively higher-grade core of approximatively 300 metres by 150
metres developed over a vertical extent of approximately 300
metres, which remains open in multiple directions.
-
Valja Saka prospect: Scout exploration drilling
encountered strong skarn-altered sediments with garnet and
magnetite and occasional visible gold, analogous to the Čoka Rakita
style of mineralization. Additionally, drillhole VSDD010 confirmed
the potential for polymetallic carbonate replacement mineralization
with significant silver, copper, zinc and lead grades.
-
Preliminary metallurgical tests: Achieved copper
rougher recoveries associated with samples from the Dumitru Potok,
Rakita North and Frasen prospects of over 90% at a grind size of
75µm. These preliminary results indicate the potential for lower
energy consumption and consistent copper concentrate grades. This
aligns with the average bond work index figures and indicates
promising characteristics for ore processing.
-
Next steps: DPM is pursuing potential skarn and
manto-like stratabound targets with a 55,000-metre scout and target
delineation drilling campaign, focused on the Čoka Rakita licence,
including the Dumitru Potok prospect, as well as the Potaj Čuka and
Pešter Jug licences. Based on these positive results, dedicated
target delineation drilling will be allocated to high priority
targets with up to 15 rigs expected to be deployed by early
spring.
“These impressive results at Dumitru Potok
clearly demonstrate the existence of a large copper-gold deposit
that has the potential to provide additional high-grade mineral
resources adjacent to the planned infrastructure of Čoka Rakita.
The drill program continues to expand the Dumitru Potok discovery,
and we have yet to define its limits as it remains open in multiple
directions and at depth,” said David Rae, President and Chief
Executive Officer of Dundee Precious Metals.
“Our exploration team and strong financial
position has continued to add value through the drill bit,
supported by our strategy to create a robust platform for growth to
deliver above-average returns for our shareholders.”
Scout Drilling Program Overview
The Company has continued to progress its scout
drilling program, completing over 18,000 metres and 23 drill holes
since the previous update on September 11, 2024, with nine drill
holes in progress.
See Figures 1, 2 and 3 for plan, section and 3D
views highlighting recent drilling at the Dumitru Potok, Rakita
North and Valja Saka prospects.
At the Dumitru Potok prospect,
located approximately one kilometre northeast of Čoka Rakita, a
directional target delineation drilling program is ongoing with
multiple daughter holes outlining a sub-vertical monzodiorite
intrusive body, with proximal high-grade stratabound
copper-gold-silver mineralization on the conglomerate-marble
unconformity and along the marble-intrusive contact zone.
Based on the drilling to date, stratabound
conglomerate-marble unconformity hosted mineralization extends
outward from the eastern and western margins of the causative
intrusion. Mineralization can be traced for more than one kilometre
of strike length and up to 500 hundred metres away from the
causative intrusion and varies in thickness from five metres to up
to 40 metres. Mineralization on the marble-intrusive contact zone
is developed for more than 300 metres vertically, either as contact
skarns or as stratabound lenses within reactive marbles, including
on the lower marble-basement contact. The mineralization is open in
all directions and its full footprint and grade continuity have yet
to be defined.
On the east flank of the Dumitru Potok
intrusive, DPDD025A was collared to test below holes DPDD012 and
DPDD012A, and encountered a wide zone of strong skarn alteration
and mineralization developed on marbles and returned an intercept
of 190 metres at 2.07% Cu, 1.23 g/t Au and 12.19 g/t Ag, which
includes a higher grade zone of 49 metres at 4.18% Cu, 1.48 g/t Au
and 21.7 g/t Ag.
See Figure 4 for details of the mineral
assemblage in DPDD025A.
On the west flank of Dumitru Potok intrusive,
drill hole DPDD026 confirmed the extension of strong mineralization
to the south on the upper marble contact, returning 36 metres at
1.8% Cu, 1.4 g/t Au and 11.76 g/t Ag from 953 metres downhole. The
extension of the hole aimed to test the potential of the lower
marble-basement contact target and successfully intercepted a wide
zone of strong skarn alteration and mineralization of 115 metres at
1.47% Cu, 2.73 g/t Au and 9.69 g/t Ag from 1,170 metres downhole,
including 38 metres at 2.59% Cu, 4.05 g/t Au and 17 g/t Ag from
1,195 metres.
These new intercepts confirm the potential for
more than 300 metres of vertical extension in proximity to the
causative intrusion when viewed in conjunction with other
drillholes.
See Figure 5 for details of the mineral assemblage in
DPDD026.

Intervals are reported at a cut-off grade of 0.8% CuEq using 5
metres minimum length and 10 metres maximum internal dilution.
Higher grade sub-intervals denoted with ‘including’ are reported at
a cut-off grade of 3% CuEq using 5 metres minimum length and 5
metres maximum internal dilution. |
3) |
|
The CuEq calculation is based on the following formula: Cu % + Au
g/t x 0.74 + Ag g/t x 0.009 based on a copper price of $2.75/lb,
gold price of $1,400/oz and silver price of $17/oz; and assumes
metallurgical recoveries of 90% all metals within the equivalency
calculation. Metallurgical assumptions are based on initial
floatation testwork completed on the stratabound hosted Cu-Au-Ag
mineralization at Čoka Rakita North and ongoing metallurgical
testing. |
4) |
|
No upper cuts have been applied. |
5) |
|
Based on the limited understanding of the geometry of the
mineralized body, true widths are considered to be 90% or more of
the reported downhole interval, assuming strata-bound control on
the mineralization. For holes DPDD026 and DPDD025A due of potential
vertical extent of the mineralization along the contact, the true
width cannot be evaluated at this time. |
6) |
|
Daughter holes identified with “A” (e.g., DPDD025A) are
navigational holes with collar coordinates and depth indicating the
exit point from the parent hole. |
|
|
|
Based on these strong results, DPM is
accelerating the systematic target delineation drilling campaign at
Dumitru Potok to further extend these high-grade zones and build
additional confidence on the shape, size and grade tenor of the
encountered mineralization.
At the Rakita North target,
located on the northwestern flank of the Čoka Rakita deposit and
proximal to planned underground development, two deep holes have
been completed that intercepted significant copper-gold
mineralization over most of the 300-metre thickness of the marbles.
Mineralization is a combination of manto-like skarn mineralization
on the upper and lower contact, as well as more discrete
replacement and stockwork veins over the entire marble lithological
package.
These results include hole RADDHG008, which
reported 30 metres at 0.52% Cu, 0.42 g/t Au and 2.31 g/t Ag from
1,074 metres downhole and 105 metres at 0.69% Cu, 0.51 g/t Au and
2.81 g/t Ag from 1,120 metres downhole. Additional results include
hole RADD050, which returned 40 metres at 0.64% Cu, 0.49 g/t Au and
1.81 g/t Ag from 780 metres downhole and 140 metres at 0.88% Cu,
0.6 g/t Au and 2.94 g/t Ag from 990 metres downhole. These drill
intercepts are approximately 500 metres below the Čoka Rakita
planned underground infrastructure (see Figure 3).
These new drill intercepts show significant
copper-gold mineralization developed over an up to 300-metre
vertical section, by more than 300 metres by 150 metres laterally,
and remains open in multiple directions. Further drilling is
ongoing, including daughter holes to follow-up hole RADD050 as well
as additional scout holes from surface aimed to test continuity
towards Dumitru Potok and the larger potential extensions to east
and southeast.

Scout exploration drilling commenced at the
Valja Saka prospect, which is located
approximately two kilometres north of Čoka Rakita, targeting
shallow skarn-altered marble and sandstone-hosted gold-silver-base
metals mineralization, previously mapped in the area. Several holes
from the program encountered strong skarn-altered sediments with
garnet and magnetite and occasionally with visible gold, analogous
to the Čoka Rakita style of mineralization.
Of note is VSDD010 drillhole which was collared
as a long scout hole to follow-up on a magneto-telluric (“MT”)
conductivity anomaly. This hole intersected a zone of skarn
alteration with visible gold that returned 8.3 metres at 5.31 g/t
Au from 325 metres downhole. The hole continued into a weakly
mineralized copper-gold porphyry, which then passed into a zone of
polymetallic, carbonate replacement mineralization that returned 15
metres at 0.62 % Cu, 0.66 g/t Au and 21.9 g/t Ag from 808 metres
downhole, and 20 metres at 0.17 % Cu, 93 g/t Ag, 5.15 % Zn and 1.48
% Pb from 848 metres downhole.
The shallow gold skarn target was followed up by
VSDD011 that reported a narrow interval with coarse visible gold of
4.6 metres at 43.95 g/t Au and 0.15% Cu from 302.4 metres downhole
and by VSDD012 that reports 9 metres at 2.69 g/t Au and 0.14 % Cu
from 237 metres downhole.

Intervals are reported at a cut-off grade of 1g/t AuEq using 5
metres minimum length and 5 metres maximum internal dilution.
Higher grade sub-intervals denoted with ‘including’ are reported at
a cut-off grade of 5 g/t AuEq using 5 metres minimum length and 5
metres maximum internal dilution. |
3) |
|
The AuEq calculation is based on the following formula: Au g/t + Cu
% x 1.35 + Ag g/t x 0.012 + Pb % x 0.39 + Zn % x 0.61 based on a
copper price of $2.75/lb, gold price of $1,400/oz, silver price of
$17/oz, lead prices of $0.8/lb and zinc price of 1.25$/lb; and
assumes metallurgical recoveries of 90% all metals within the
equivalency calculation. Metallurgical assumptions are based on
testing of other polymetallic showings within the license
area. |

|
No upper cuts have been applied. |
5) |
|
Based on the limited understanding of the geometry of the
mineralized body, true widths cannot be calculated at this
time. |

The mineralization remains open in multiple directions and will
be tested as part of DPM’s upcoming 55,000-metre drilling
campaign.
See Figure 3 for a better understanding of the spatial
disposition of different targets.

Initial bulk rougher tests at a grind size of
75µm indicate that copper responds well to flotation with
recoveries above 90% after the first ten minutes of testing. These
preliminary results indicate the potential for lower energy
consumption and consistent copper concentrate grades. This aligns
with the average bond work index figures and indicates promising
characteristics for ore processing. However, pyrite (for sample
BI1) and non-sulphide gangue (for the rest of the samples)
recoveries increase into the concentrate in the last ten minutes of
float, which is suspected to be diluting rougher concentrate copper
grades and will be an area for improvement in subsequent
metallurgical testing programs.

Initial gravity testing indicated a variable
gravity gold recoverable component from between 22.3% to 57.6% for
the DP1 sample. Copper losses to gravity concentrate also vary,
with BI1 having a low copper loss of only 1.6% whilst DP2, DP3 and
RA1 lost 9.2%, 16.4% and 12.3% respectively. The results
indicate limited amounts of freely recoverable gold, which
generally aligns with the flotation testwork where both the silver
and gold appeared to respond well to flotation. Importantly, silver
and gold experienced relatively quick recovery to the concentrates,
suggesting an association with sulphides.

The results to date demonstrate high recoveries
are achievable, albeit with a significant mass pull, attributed to
elevated levels of pyrite in certain samples, while others exhibit
a higher presence of unspecified gangue. Future testing will focus
on reducing mass pull by examining the effects of grind size on
non-sulphide gangue and pyrite recovery, as well as exploring the
advantages of incorporating a cleaning circuit for concentrate
enhancement. Ongoing testwork includes a detailed mineralogical
investigation to determine a range of key mineralogical
criteria.
Significant 2025 Exploration Program
Ongoing
DPM’s exploration program includes
approximatively 55,000 metres of drilling to follow-up on positive
results to extend existing zones of mineralization and to continue
testing enhanced targeting models. A portion of this drilling will
be dedicated to the Dumitru Potok and Frasen target delineation
programs, which will aim to define the stratabound-hosted
mineralization, which is open in multiple directions, and to better
understand the continuity of the mineralization along strike and
away from the causative intrusions.
Furthermore, the Company is following up on a
full-tensor MT survey that has been conducted over Dumitru Potok
and the eastern portion of the northmost Potaj Čuka licence, which
highlighted several significant conductive targets that can be
traced over six kilometres along strike north of the Dumitru Potok
prospect. The Potaj Čuka licence shares the same geological setting
as the Dumitru Potok and Frasen prospects and is highly prospective
for skarn, carbonate replacement and porphyry style
mineralization.
The mineralized domains at Dumitru Potok are
identified as distinct conductive areas, likely influenced by
intrusive rocks such as dykes and sills, as well as the surrounding
skarn alteration and mineralization. In most cases, the intercepted
mineralization spatially aligns with the edges of conductive
anomalies or directly with the most conductive sections. The
resistivity model indicates the presence of subvertical conductive
"channels" extending to depths greater than two kilometres.
A 3D seismic survey, using irregular source grid
and >9000 Stryde geophones at 25 metres by 25 metres, was
completed over Dumitru Potok that aimed to evaluate the
relationship between structures, intrusive bodies and the
sedimentary unconformities that are coincident with the wide,
high-grade mineralization zones encountered to date. The analysis
of the 3D seismic model is ongoing and it is expected that this
model will provide information concerning the system architecture
to guide scout and target delineation drilling campaigns.
The Company has budgeted between $23 million and
$25 million for exploration activities in Serbia in 2025.

Sampling, Analysis and QAQC of Exploration Drill Core
Samples
Most exploration diamond drill holes are
collared with PQ size, continued with HQ, and are sometimes
finished with NQ and BQ diameters. Triple tube core barrels and
short runs are used whenever possible to improve recovery. All
drill core is cut lengthwise into two halves using a diamond saw:
one half is sampled for assaying and the other half is retained in
core trays. The common length for sample intervals within
mineralized zones is one metre. Weights of drill core samples range
from three to eight kilograms (“kg”), depending on the size of
core, rock type, and recovery. A numbered tag is placed into each
sample bag, and the samples are grouped into batches for laboratory
submission.
Drill core samples are shipped to the Company’s
own exploration laboratory in Bor, Serbia, which is independently
managed by SGS. SGS methods and procedures are accredited at SGS
hub labs and independent internal lab QAQC check samples are sent
to an SGS accredited laboratory. The Bor lab also participates in
SGS monthly round robins, and other international Round Robins.
Quality control samples, comprising certified reference materials,
blanks, and field duplicates, are inserted into each batch of
samples and locations for crushed duplicates and pulp replicates
are specified. All drill core and quality control samples are
tabulated on sample submission forms that specify sample
preparation procedures and codes for analytical methods. For
internal quality control, the laboratory includes its own quality
control samples comprising certified reference materials, blanks
and pulp duplicates. All QAQC monitoring data are reviewed,
verified and signed off by an independent QAQC geologist. Chain of
custody records are maintained from sample shipments to the
laboratory until analyses are completed and remaining sample
materials are returned to the Company. The chain of custody is
transferred from the Company to SGS at the laboratory door.
At the SGS Bor laboratory, the submitted drill
core samples are dried at 105°C for a minimum of 12 hours and then
jaw crushed to approximately 80% passing four millimetres. Sample
preparation duplicates are created by riffle splitting crushed
samples on a 1-in-20 basis. Larger samples are riffle split prior
to pulverizing, whereas smaller samples are pulverized entirely.
Pulverization specifications are 90% passing 75 microns. Gold
analyses are done using a conventional 50-gram fire assay and AAS
finish. Multi-element analyses for 49 elements, including Ag, Cu,
Mo, As, Bi, Pb, Sb, and Zn, are done using a four-acid digestion
and an ICP-MS finish at SGS Bor and SGS Ankara laboratories.
Samples returning over 10 ppm for Ag and 1% for Cu, Pb or Zn are
analyzed with AAS finish. Sulphur is analyzed using an Eltra
Analyzer equipped with an induction furnace.
