TORONTO, March 30, 2021 (GLOBE NEWSWIRE) -- Dundee Precious Metals Inc. (TSX: DPM) (“DPM” or “the Company”) is pleased to announce a mine life extension and updated Mineral Resource and Mineral Reserve estimate for the Chelopech mine in Bulgaria. The Mineral Resource and Mineral Reserve estimates for DPM’s Ada Tepe mine in Bulgaria and Timok gold project in Serbia remain unchanged from the estimates previously reported in the news releases dated October 16, 2020 and February 23, 2021, respectively.

Highlights

• 10% net addition to Mineral Reserves: Successfully added 3.9 million tonnes (“Mt”) to Mineral Reserves, which more than offset 2020 production depletion of 2.2 Mt for a net addition of 1.7 Mt. Relative to the previous Mineral Reserve estimate, this represents an increase of 10% in tonnage and an increase in metal content of 5% for gold, 13% for silver and 3% for copper;
• Mine life extended to 2029: Proven and Probable Mineral Reserves of 1.7 million ounces (Moz.) of gold and 344.4 million pounds (Mlbs.) of copper supports an optimized mine life that extends to 2029 as well as the Company’s previously issued three-year outlook for Chelopech;
• 22% increase to Measured and Indicated Mineral Resources: Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, increased 22%, representing a 3.2 Mt net increase in tonnage and an increase in metal content of 12% for gold and 6% for copper, further adding to the potential to extend mine life, if such Mineral Resources are converted to Mineral Reserves;
• Additional potential with in-mine and brownfield exploration: Significant drilling program planned for 2021, including 44,000 metres of in-mine drilling and 38,000 metres of drilling on prospective brownfield targets.

“We continued our strong track record of extending mine life at our Chelopech mine in 2020, with net additions to our Mineral Reserves and Mineral Resources compared with 2019 estimates,” said David Rae, President and Chief Executive Officer of Dundee Precious Metals. “With Mineral Reserves that now extend to 2029, an updated Mineral Resource base and increased in-mine and brownfield exploration drilling, we believe there is strong potential for this trend to continue at Chelopech.”

Updated Mineral Resource and Mineral Reserve Estimate

The updated Mineral Resource and Mineral Reserve estimate for the Chelopech mine reflects the conversion of Mineral Resources to Mineral Reserves, as well as a strategic mine plan optimization process that was completed in Q3 2020. The strategic optimization process included an analysis of multiple mine schedules at various cut-off values (“CoV”), with the primary objectives focused on optimizing net present value and the life of mine (“LOM”). Of the overall increase to Mineral Reserves, approximately 20 to 25% was added as a result of the conversion of new Mineral Resources generated by in-mine drilling activities, with the balance of the increase resulting from the optimization of the CoV and other design parameters.

Total Proven and Probable Mineral Reserves at Chelopech of 1.7 Moz. of gold and 344.4 Mlbs. of copper support an eight-year mine life that extends to 2029, prior to any further conversions from existing Mineral Resources or additional exploration success.

The Mineral Reserves statement is shown below and is effective as of December 31, 2020.

Mineral Resource and Mineral Reserves Estimation Approach

Mineral Resources and Mineral Reserves for Chelopech are reported using a net smelter return (“NSR”) methodology to determine the profitability of each stope in the mine plan. NSR refers to revenues expected from the mill feed, taking into consideration metal prices, mill and smelter recoveries, concentrate grades, transportation costs of the concentrate to the smelter, treatment and refining charges, and other smelter deductions.

This approach has many benefits, versus using a single metal cut-off grade, including: polymetallic ore grades can be converted into a profitability variable expressed in terms of U.S. dollars per tonne; the value of Mineral Reserves can be quickly compared to applicable costs to determine their viability; cut-off grades become cut-off NSRs; during the extraction process, the value of an area or a stope can be quickly estimated; and, the effect of commodity price fluctuations can be quickly evaluated.

Chelopech Mineral Reserves are based on an NSR cut-off value of $1,400 per oz. for gold, $17 per oz. for silver, and $2.75 per lb. for copper plus a profit margin of $10 per tonne. The current NSR assumptions are equivalent to an NSR using $1,250 per oz. of gold at a $5 per tonne profit margin, and better reflect the long-term potential of the ore body by ensuring the extraction of profitable stopes at relatively conservative long-term metal prices.

Prior Mineral Reserve estimates for the Chelopech mine were based on a price of $1,250 per oz. of gold plus a $10 per tonne profit margin. This equates to approximately a $1,000 per oz. gold price at a $0 per tonne margin, which is regarded as low given the longer-term outlook for metal prices. Therefore, DPM refined its assumptions to support the determination of the optimal mine value and mine life.

Life of Mine Plan

The table below shows the current LOM plan, reflecting the updated Mineral Reserves estimate. The updated LOM plan adds approximately 228,000 oz. of gold production and 43 Mlbs. of copper production between 2021 and 2029, relative to the previous mine plan outlined in the technical report for Chelopech entitled “NI 43-101 Technical Report – Mineral Resource and Reserve Update, Chelopech Mine, Bulgaria” dated March 30, 2020.

Further extending mine life through additional in-mine and brownfield exploration

DPM continues to focus on extending Chelopech’s mine life through its in-mine and brownfield exploration programs, with an intensive program planned for 2021 which includes:

• Approximately 44,000 metres of in-mine drilling. From that total, approximately 33,000 metres will be focused on delineating extensions of existing orebodies as well as testing historically underexplored sections of the mine, with the remainder to be focused on operational grade control works; and
• Approximately 38,000 metres of brownfield exploration, concentrated on near mine exploration drilling related to the Sveta Petka commercial discovery process, which includes the West Shaft and Wedge targets, and on drilling more conceptual targets on the Brevene exploration license, including Bridge and Vozdol.

In line with the Company’s 2021 guidance, exploration spending is expected to be $13 to $15 million, of which approximately 50% has been allocated to support the exploration program at Chelopech.

In-mine exploration

In 2020, approximately 45,000 metres of Mineral Resource development diamond drilling were completed, with a focus on grade control drilling to better define the shape and volume of existing orebodies and to test for new mineralization along modeled trends. Drilling was concentrated on targets in the upper levels of the Chelopech deposit, and the program resulted in the addition of two new ore bodies to the Mineral Resource inventory.

The 2021 Mineral Resource development strategy for Chelopech will focus on the upper levels of Blocks 5, 8,17, 25, 144, 145, 149 and 700. Extensional and exploration drilling targets include an area south-east from Block 8, which is a largely unexplored target that exhibits prospective structural and alteration indicators. Drilling at target 19NE will test for narrow lenses of sulphide mineralisation, branching out from the main Block 19 orebody. Additionally, target areas peripheral to Blocks 25, 146, 147, 148 and 151 that exhibit prospective structural trends will be tested. A map of key extensional and exploration targets for the year is shown below.

Brownfield exploration activities

During 2020, the brownfield exploration program was focused on the surface drilling of copper-gold targets at the highly prospective Wedge and West Shaft prospects on the Sveta Petka exploration license.

At the West Shaft prospect, which is a newly discovered extension of the Chelopech hydrothermal system located approximately one-kilometre south-west of the Chelopech mine, an intensive diamond drilling exploration program began in the second half of 2020, with work to delineate and test the extension at depth ongoing. Work in 2021 will continue to focus on aggressive target delineation drilling, and to explore for an extension to the south where an additional zone of gold-copper mineralization was identified during recent drilling, approximately 250 metres southeast from the main mineralized zone. Deep directional drilling is continuing at the Wedge prospect, which is situated on the northern edge of the Chelopech mine, with a focus on testing more conceptual targets.

In January 2021, a Geological Discovery was registered with the Bulgarian Ministry of Energy for the Sveta Petka License. A work program for 2021 is currently being developed to support an application for a Commercial Discovery, which is required together with an Environmental Impact Assessment to covert the license into a mining concession.

In 2021 exploration activities on the Sveta Petka license will be focused on infill and extensional drilling required for the technical development of the Wedge, West Shaft and Krasta prospects in conjunction with the Commercial Discovery process. Additionally, following positive results of drilling completed at Wedge prospect, targeting for potential higher grades of the Petrovden porphyry target is underway. Target delineation drilling at the Sharlo Dere target, in the mine concession, will commence during the second quarter.

On the broader Brevene exploration license scout drilling of priority targets, including the Bridge Target, has commenced. A targeting study to evaluate the Vozdol prospect has been completed and drilling on selected priority targets will commence during the second quarter.
