Dundee Precious Metals Announces Additional Drill Results

TORONTO, Nov. 15, 2023 (GLOBE NEWSWIRE) — Dundee Precious Metals Inc. (TSX: DPM) (“DPM” or “the Company”) today reported new assay results from its ongoing infill drilling program at the Čoka Rakita prospect in eastern Serbia, which continued to confirm the continuity of the mineralization and locally extended the footprint of the deposit to the west and south-west. Additionally, the Company provided an update on its scout drilling program on the Čoka Rakita licence, highlighting additional potential for manto-like copper-gold skarn mineralization at the Frasen, Dumitru Potok and Rakita North targets.

Highlights

• Exceptional new high-grade intercepts from infill drilling, including:
  • RIDT025 – 36 metres at 2.59 g/t Au from 377 metres downhole and 73 metres at 43.36 g/t Au and 0.12% Cu from 420 metres downhole (including 41 metres at 76.08 g/t Au and 0.16% Cu from 446 metres downhole)
  • RIDT026 – 30 metres at 7.44 g/t Au from 439 metres downhole and 38 metres at 14.94 g/t Au from 477 metres downhole
  • RIDT028 – 91 metres at 15.09 g/t Au and 0.11% Cu from 404 metres downhole (including 28 metres at 13.14 g/t Au from 437 metres downhole) and 11 metres at 83.29 g/t Au and 0.12% Cu from 480 metres downhole
  • RIDD030 – 47 metres at 6.47 g/t Au from 470 metres downhole
  • RIDD031 – 38 metres at 18.47 g/t Au from 562 metres downhole and 24 metres at 4.54 g/t Au and 0.12% Cu from 506 metres downhole
  • RIDT005 – 45 metres at 3.17 g/t Au and 0.21% Cu from 353 metres downhole (including 7 metres at 10.25 g/t Au and 0.17% Cu from 357 metres downhole)
  • RIDD036 – 23 metres at 6.95 g/t Au from 441 metres (including 11 metres at 12.85 g/t Au from 453 metres downhole)
  • RIDD029 – 43 metres at 3.23 g/t Au from 602 metres downhole
  • RIDD037 – 26 metres at 3.71 g/t Au and 0.12% Cu from 456 metres downhole (including 8 metres at 7.59 g/t Au from 461 metres downhole)

• Results confirm and locally extend the high-grade core of mineralization: Results from RIDT025, RIDT026 and RIDT028 confirm the high-grade nature of the mineralized body and provide additional confidence in the continuity of the mineralization (see Figure 1). High-grade intercepts from holes RIDT025 and RIDT028 extend the high-grade core by 80 metres to the south and 70 metres to the east-northeast, respectively, of hole RADDMET001 (which included the previously announced intercept of 40 metres at 63.43 g/t Au and 0.11% Cu from 517 metres depth).¹
• Results extend the deposit to the southwest and northeast: Holes RIDD036 and RIDT005 extend the mineralization to the southwest and demonstrate that prospective exo-skarns are developed further than originally interpreted, while holes RIDD029 and RIDD037 demonstrate that the system is still open to the northeast at these locations. Follow-up extensional drilling is planned to better define the limits of mineralization.
• Scout drilling outlines further extensional potential of the deposit with multiple targets currently being tested: Drilling intercepted skarn-altered sandstones and conglomerates on the northeast flank of the system and also intercepted a significant (more than 160 meters thick in RADD044 drillhole) package of skarn-altered marbles hosting copper-gold mineralization at depth (see Figure 2).
• New exploration licences provide further upside potential: Includes the Potaj Čuka exploration licence, which is located to the north of Čoka Rakita and contains the Timok gold project, and the Pešter Jug exploration licence, located to the south of Čoka Rakita (see Figure 3). DPM is planning a 25,000-metre drilling campaign to test favourable stratigraphy for carbonate replacement and skarn deposits on both new licences.
• Next steps: DPM expects to complete a maiden Mineral Resource estimate for Čoka Rakita in December 2023 and continues to advance activities aimed at accelerating the project, including initiating geotechnical and hydrogeological drilling, the next phase of the metallurgical testwork program, evaluation of locations for potential site infrastructure, and stakeholder engagement activities. The Company is also aggressively pursuing additional potential skarn targets through its scout drilling campaigns within the Čoka Rakita licence, on the new Potaj Čuka and Pešter Jug licences, and the 10,000-metre scout drilling program on the Umka licence.

“We are excited to announce these exceptional results from our ongoing drilling program at the high-quality Čoka Rakita prospect in Serbia, including the best intercept to date with 73 metres at 43 grams per tonne gold and 0.12% copper,” said David Rae, President and Chief Executive Officer of Dundee Precious Metals.

“We are on track to complete a maiden Mineral Resource estimate by the end of 2023, and we are continuing to advance activities aimed at accelerating this high-quality growth prospect. We are also aggressively drilling to further grow the deposit and test other prospective targets on the nearby Umka, Potaj Čuka and Pešter Jug exploration licences.”

Čoka Rakita Infill Drilling Program Results

The Company is continuing its accelerated drilling program at Čoka Rakita, with an additional 21,250 metres drilled and 44 infill holes completed since the previous update on July 11, 2023, with another 5 drill holes currently in progress.

The infill drilling program continues to demonstrate gold grade continuity, particularly in the central areas of the mineralization. Multiple holes (RIDD030, RIDD031, RIDD035, RIDT025, RIDT026 and RIDT028) have confirmed the presence of intensively mineralized skarn within the core of the deposit, having returned consistent and wide intercepts of high-grade gold mineralization, frequently associated with visible gold.

In addition to confirming the exploration targeting model for Čoka Rakita, the drilling program has extended the footprint of the high-grade core of the deposit by approximately 55 metres to the south and 30 metres to the east (see Figure 1). While the overall extents of the deposit remain consistent with the dimensions previously reported in July 2023 (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),² drilling has improved confidence in working interpretations and locally extended the outer limits of the mineralization to the southwest by 30 metres (RIDT005 and RIDD036), and to the northeast by 60 metres (RIDD029 and RIDD037). Further delineation drilling is planned for these areas as the drill program progresses.

Results from the 40 new holes of the infill program are disclosed in the following table, while for 4 completed holes the assays are pending.

Table 1: New drill intercepts from the Čoka Rakita infill drilling

* Holes have been assayed using a 50 g Fire Assay method, Screen Fire Assays (SFA) results pending.

1) Coordinates are in UTM Zone 34 North WGS84 datum.

2) Intervals are reported at a cut-off grade of 1 g/t AuEq using 5 metres minimum length and 5 metres maximum internal dilution. Higher grade ‘Including’ intervals are reported at a cut-off grade of 5 g/t AuEq using 5 metres minimum length and 3 metres maximum internal dilution.

3) The AuEq calculation is based on the following formula: Au g/t + 1.35 x Cu %, based on a gold price of $1,400/oz. and a copper price of $2.75/lb.; and assumes metallurgical recoveries of 90% for gold and 90% for copper within the equivalency calculation. These assumptions are based on preliminary metallurgical results and expected similar behaviour of copper and gold during flotation. Copper below 0.1% has not been reported and is not included in the equivalency calculation.

4) No upper cuts have been applied.

5) Based on the current understanding of the geometry of the mineralized body, true widths are considered to be 90% or more of the reported downhole interval.

6) “DT” within the hole naming nomenclature (e. g. RIDT005) indicates that the hole is a diamond tail of a reverse circulation pre-collar drillhole.

7) Daughter holes identified with “A” (e.g., RIDT030A) are navigational holes with collar coordinates indicating the exit point from the parent hole.

Čoka Rakita Scout Drilling

The Company is accelerating its scout drilling program on the Čoka Rakita exploration licence and has drilled over 9,000 metres to date, with eight drillholes completed and three drillholes in progress. The objective of the drilling program is to test for the continuation of sandstone skarn and conglomerate-hosted mineralization under cover, as well as for deeper-seated marble-hosted copper-gold targets.

To enhance its exploration targeting, the Company completed a magnetotellurics (MT) survey covering two square kilometres in the vicinity of the Čoka Rakita and Dumitru Potok targets. The MT survey identified several deep-seated distinct conductivity anomalies located on the flanks of the Dumitru Potok porphyry system and extending towards the north flank of the Čoka Rakita and Frasen prospect areas.

Scout holes drilled north of Čoka Rakita, toward the Frasen and Dumitru Potok prospects, intercepted copper-gold mineralization hosted by conglomerates and marbles. Notably, hole RADD044 intercepted wide zones of copper-gold mineralization within skarn-altered marbles and returned 50 metres at 0.54% Cu and 0.41 g/t Au from 1220 metres downhole and 42 metres at 0.72% Cu and 0.5 g/t Au from 1277 metres downhole. These results, when combined with other intercepts from the hole, suggest a vertical extent of over 160 metres. Along with RADD043 and previously published intercepts in RIDD001, RIDD002 and RIDD009, these intercepts outline the potential for a significant marble hosted skarn copper-gold target on the northern flank of Čoka Rakita at deeper levels.

At the Frasen prospect, located approximately one kilometre north of Čoka Rakita, BIDD0221 returned 5 metres at 1.45% Cu and 0.64 g/t Au from 486 metres downhole. This copper-gold mineralization is of a carbonate replacement type and hosted within marbles. Additional drilling is underway to test the continuity of this target.

At the Dumitru Potok prospect, located approximately 1.5 kilometres northeast of Čoka Rakita, several holes intercepted lower grade copper-gold porphyry mineralization and, at shallower depths, showed potential for sandstone and conglomerate hosted gold mineralization. From this program, DPDD010 reported 9 metres at 0.59% Cu and 0.33 g/t Au from 555 metres downhole, while assays from the other holes are pending.

For details of the Čoka Rakita scout drilling program, refer to Table 2 and Figure 2.

1) Coordinates are in UTM Zone 34 North WGS84 datum.

2) Intervals are reported at a cut-off grade of 1 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 + 1.35 x Cu %, based on a gold price of $1,400/oz. and a copper price of $2.75/lb.; and assumes metallurgical recoveries of 90% for gold and 90% for copper within the equivalency calculation. These assumptions are based on preliminary metallurgical results and expected similar behaviour of copper and gold during flotation. Copper below 0.1% has not been reported and is not included in the equivalency calculation.

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.

Metallurgical Testing

To confirm the favourable results of the previously reported metallurgical testwork, a new comprehensive metallurgical testing program was completed for Čoka Rakita. The results confirmed the viability of a combined gravity concentration and flotation circuit at different target grades.

Three representative 150 kg composite samples were tested at Base Metallurgical Laboratories in Kamloops, British Columbia. Extended gravity recoverable gold (“EGRG”) testing demonstrated gravity recoverable gold ranging from 49% to 62% from these samples. Rougher flotation tests on the gravity tails at a P80 grind size of 53 µm achieved overall gold recoveries ranging from 90% to 96% for the three composite samples. Adjusting for cleaner flotation losses, the results indicate total achievable gold recovery from a gravity and flotation circuit ranges from 88% to 91%.

Comminution testing was also performed on these samples and determined a Bond Ball Mill Work Index of 13.4 kW/t and an Abrasion Index of 0.14. These results indicate that the material is of average hardness and mildly abrasive.

Table 3: Metallurgical test results

These encouraging results validate the suitability of mineralized material at Čoka Rakita for gravity concentration followed by conventional froth flotation, and this flowsheet will be the basis for further optimization during subsequent testwork phases.

Next Steps for Čoka Rakita

• Maiden Mineral Resource estimate: DPM expects to complete a maiden Mineral Resource estimate in December 2023. The Mineral Resource estimate will incorporate results from drilling up until the end of October 2023.
• Ongoing activities to accelerate advancement of the project: DPM continues to advance activities aimed at accelerating the project, which includes initiating geotechnical and hydrogeological drilling, the second phase of the metallurgical testwork program, the evaluation of locations for potential site infrastructure, and continuing stakeholder engagement activities.
• Scout drilling on the Čoka Rakita and Umka exploration licences: The Company is aggressively pursuing additional potential skarn targets through its scout drilling campaign within the Čoka Rakita licence and is continuing its 10,000-metre scout drilling program on the Umka licence.
• 25,000 metres of exploration drilling planned at the newly granted Potaj Čuka and Pešter Jug exploration licences: DPM is preparing an aggressive exploration program and plans to test favourable stratigraphy for carbonate replacement and skarn mineralization on the Potaj Čuka exploration licence, which hosts the Timok gold project and is located to the north and west of Čoka Rakita, and the Pešter Jug exploration licence, which is to the south of Čoka Rakita. The program is expected to commence in early 2024, pending approval of the work plan and permitting procedures, with approximately 25,000 metres of drilling planned for the first year of exploration on these licences.

About Čoka Rakita

The Čoka Rakita prospect is located three kilometres southeast of the Bigar Hill sediment-hosted gold deposit (Timok gold project) and forms part of the of the Timok Magmatic Complex (TMC) in eastern Serbia. The surface footprint of the target was delineated by a combination of soil geochemistry, alteration mapping and geophysical signatures. The drilling to-date has defined a manto-like zone of shallow-dipping gold-rich skarn mineralization located on the contact zone of a carbonate rich sandstones and fertile diorite intrusive sills and dikes. At shallower depths, scout drilling has defined additional potential for conglomerate and marble hosted copper-gold mineralization.

Sampling, Analysis and QAQC of Exploration Drill Core Samples

Given the presence of coarse gold at Čoka Rakita, a rigorous sampling and QAQC procedure has been selected which includes the use of laboratory screen metallic assaying.

Most exploration diamond drill holes are collared with PQ size, continued with HQ, and are sometimes finished with NQ. 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 participate 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. Samples returning over 10 ppm for Ag and 1% for Cu, Pb or Zn are re-analyzed using high grade methods with AAS. Sulphur is analyzed using an Eltra Analyzer equipped with an induction furnace.

All fire assays performed at SGS Bor with results exceeding 1 g/t gold grade are re-assayed by means of a specifically designed gold screen fire assay program at the ALS Global laboratory located in Romania. For re-analyses, 1 kg of 2 mm sized coarse reject material is split, pulverized and screened at 106 microns to separate the sample into a coarse fraction (>106 µm) and a fine fraction (<106 µm). After screening, two 50-gram aliquots of the fine fraction are analyzed using the traditional fire assay method and AAS finish. The entire coarse fraction is assayed to determine the contribution of the coarse gold using fire assay and gravimetric finish. A “total” gold calculation for the 1 kg sample is based on the weighted average of the coarse and fine fractions.
