Dundee Precious Metals Announces Mine Life Extension and Update to Mineral Resource and Mineral Reserve Estimates for Chelopech

TORONTO, March 31, 2022 - Dundee Precious Metals Inc. (TSX: DPM) ("DPM" or "the Company") is pleased to announce a mine life extension, optimized life of mine ("LOM") plan and updated Mineral Resource and Mineral Reserve estimates for the Chelopech mine in Bulgaria.

Highlights

• Mine life extension to 2030: Proven and Probable Mineral Reserves of 1.7 million ounces ("Moz.") of gold and 341.9 million pounds ("Mlbs.") of copper supports a mine life that now extends to 2030.¹ In 2021, DPM successfully added 3.0 million tonnes ("Mt") to Mineral Reserves, which more than offset 2021 production depletion of 2.2 Mt for a net addition of 0.8 Mt.
• Optimized life of mine plan with improved recoveries and higher gold and copper production: The updated LOM plan reflects changes, relative to the previous mine plan, that includes improved metallurgical recoveries, concentrate terms and a reduction in the cut-off value, which maximizes net present value. Production increased by approximately 286,000 ounces ("oz.") of gold and 47 Mlbs. of copper between 2022 and 2030¹, reflecting higher recoveries for gold and copper.
• Strong Measured and Indicated Mineral Resource base: Total Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, of 1.26 Moz. of gold and 270 Mlbs. of copper add further potential to extend mine life.
• Additional potential with in-mine and brownfield exploration: Significant drilling program planned for 2022, including 44,000 metres of in-mine drilling and 50,000 metres of brownfield drilling largely focused on Sveta Petka to support a commercial discovery application.

"The optimized life of mine plan at Chelopech results in higher gold and copper production and allows us to extend mine life to 2030," said David Rae, President and Chief Executive Officer of Dundee Precious Metals.

"Our updated Mineral Reserve estimate is an indication of Chelopech's consistent track record of replacing Mineral Reserves, and we believe there is strong potential to continue this trend going forward."

¹ Subject to the extension of the current concession contract, which expires in July 2029. DPM intends to submit an extension application when appropriate and expects that the application will be successful based on previous regulatory processes.

Updated Mineral Reserve and Resource Estimate

The updated Mineral Reserves estimate is shown below and is effective as of December 31, 2021:

Footnotes:

1. The Mineral Reserves disclosed herein have been estimated in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (the "CIM Definition Standards", adopted by CIM Council on May 10, 2014).
2. Mineral Resources are reported exclusive of Mineral Reserves.
3. Mineral Reserves have been depleted for mining as of December 31, 2021.
4. The Inferred Mineral Resources do not contribute to the financial performance of the project and are treated in the same way as waste.
5. The reference point at which the Mineral Reserves are defined is where the ore is delivered to the crusher.
6. Long term metal prices assumed for the evaluation of the Mineral Reserves and Mineral Resources are $1,400/oz. for gold, $17.00/oz. for silver, and $2.75/lb. for copper.
7. Mineral Reserves are based on a net smelter return-less-costs cut-off value of $0/t. The total cost applied was approximately $45/t, which is a sum of the operational cost of approximately $40/t (variable by stope location) and sustaining capital of $5/t.
8. All blocks include a complex net smelter return ("NSR") formula that differs for the three ore types within the Mineral Reserve and Mineral Resource. The NSR formula utilizes long-term metal prices, metallurgical recoveries, payability terms, treatment charges, refining charges, penalty charges (deleterious arsenic), concentrate transport costs, and royalties. For clarity of understanding of ore value, a simplified formula is presented here that correlates to the complex formula to within 1%. The simplified formulas per ore type are:
   1. Block 700 NSR $/t = 0.00 x Cu% + 0.00 x Ag_g//t + 14.24 x Au_g/t
   2. Block 152 NSR $/t = 21.08 x Cu% + 0.32 x Ag_g/t + 33.96 x Au_g/t
   3. General NSR $/t = 16.72 x Cu% + 0.23 x Ag_g/t + 29.18 x Au_g/t
9. Mineral Reserves account for unplanned mining dilution and ore loss that varies by orebody dimension and experience per mining block area, which on average were 10.0% for unplanned ore loss and 9.7% for unplanned dilution.
10. Mineral Reserves account for planned mining dilution and mining recovery through stope optimization and stope design. The stopes are optimized to maximize net cash flow within the constraints of dilution and orebody extractable geometry. The planned dilution and recovery depend on geotechnical, mineralization continuity controls and ore zone dimensions.
11. All stopes have been verified that they are profitable after considering the cost of capital development.
12. There is no known likely value of mining, metallurgical, infrastructure, permitting or other relevant factors that could materially affect the estimate. The final one and a half years of operation occurs after the termination of the mining concession contract ends. It is the opinion of DPM that the mining permit will be extended.
13. The Proven Mineral Reserve includes broken stocks of 28 kt at 3.30 g/t Au, 5.2 g/t Ag and 0.91% Cu as well as stockpiles of 13 kt at 3.05 g/t Au, 6.7 g/t Ag and 0.96% Cu.
14. Sum of individual table values may not equal due to rounding.
    

The updated Proven and Probable Mineral Reserves at Chelopech of 1.7 Moz. of gold and 341.9 Mlbs. of copper support a nine-year mine life that extends to 2030, excluding expected further conversions of existing Mineral Resources and potential additional exploration success.

The Mineral Resource estimate has been depleted by all mining and development work completed as of December 31, 2021 and is reported using a NSR calculation based on assumed long-term metal prices, current operating costs and metal revenue to meet the "reasonable prospects for eventual economic extraction" criteria.

Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, decreased by 3.6Mt compared with 2020, as a result of conversion to Mineral Reserves, changes to classification, grade estimation and NSR parameters.

The Mineral Resource estimate is shown below and is effective as at December 31, 2021:

Footnotes:

1. The Mineral Resources disclosed herein have been estimated in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014).
2. Mineral Resources have been estimated using an operating net profit cut-off of US$0/t in support of reasonable prospects of eventual economic extraction.
3. Tonnages are rounded to the nearest 0.1 Mt to reflect that this is an estimate.
4. Metal content is rounded to the nearest 1 thousand ounces (K oz.) or 1 Mlbs. to reflect that this is an estimate.
5. The Mineral Resources are reported exclusive of Mineral Reserves.
6. Mineral Resources are based on a NSR-less-costs cut-off value of $0/t. The total cost applied was approximately $45/t, which is a sum of operational costs of approximately $40/t (variable by stope location) and sustaining capital of $5/t.
7. All blocks include a complex NSR formula that differs for the three ore types within the Mineral Reserve and Mineral Resource. The NSR formula utilizes long term metal prices, metallurgical recoveries, payability terms, treatment charges, refining charges, penalty charges, concentrate transport costs, and royalties. For clarity of understanding of ore value, a simplified formula is presented here that correlates to the complex formula to within 1%. The simplified formulas per ore type are:
   1. Block 700 NSR $/t = 0.00 x Cu% + 0.00 x Ag_g/t + 14.24 x Au_g/t
   2. Block 152 NSR $/t = 21.08 x Cu% + 0.32 x Ag_g/t + 33.96 x Au_g/t
   3. General NSR $/t = 16.72 x Cu% + 0.23 x Ag_g/t + 29.18 x Au_g/t

Life of Mine Plan

The table below shows the optimized LOM plan, reflecting the updated Mineral Reserve estimate. The updated LOM plan adds approximately 286,000 oz. of gold production and 50 Mlbs. of copper production between 2022 and 2030, relative to the previous mine plan outlined in the news release "Dundee Precious Metals Announces Mine Life Extension and Updated to Mineral Resource and Mineral Reserve Estimates for the Chelopech Mine" dated March 30, 2021. The updated LOM plan reflects the additional tonnage and higher gold recoveries following a strategic review to optimize the mine plan (the "Strategic Optimization") completed with Whittle Consulting in the second half of 2021.

The tables below show the current LOM plan compared to the previous 2021 LOM plan.

Strategic Optimization

The updated Mineral Resource and Mineral Reserve estimates for the Chelopech mine reflect the conversion of Mineral Resources to Mineral Reserves and the opportunities identified from the Strategic Optimization completed in the second half of 2021.

One of the opportunities DPM identified is continuing to sell Chelopech concentrate to third-party global smelters going forward due to strong demand. DPM evaluated the impact of this trend on the Mineral Reserves and LOM for Chelopech and conducted extensive metallurgical test work during the third quarter of 2021, which demonstrated the technical and commercial viability of producing a lower grade concentrate to meet market specifications. While the concentrate contains lower average gold and copper grades and is expected to have lower payable metal rates as well as increased offsite costs associated with higher tonnage, this is more than offset by improved overall gold recoveries and commercial terms, resulting in higher expected free cash flow for DPM as a whole.

While this is expected to reduce the proportion of Chelopech concentrate that is treated at DPM's Tsumeb smelter, the Company is confident sufficient third-party concentrate is available to fill existing capacity going forward.

The Strategic Optimization also evaluated multiple mine schedules and commercial scenarios at various cut-off values, with the primary objectives of optimizing net present value ("NPV") and mine life.

From the analysis of cut-off values, it was determined that a NSR-less-costs cut-off value of $0 per tonne resulted in the maximum NPV, whereas the prior Mineral Reserve estimate used a NSR-less-costs cut-off value of $10 per tonne. Chelopech Mineral Reserves continue to be based on a NSR-less-costs cut-off value methodology using long-term metal prices of $1,400 per oz. for gold, $17 per oz. for silver, and $2.75 per lb. for copper.

Three-Year Outlook

The updated Mineral Reserve estimate is in-line with the Company's previously issued 2021 guidance and three-year outlook for Chelopech, as shown below, with all-in sustaining cost ("AISC") per ounce of gold sold for 2023 and 2024 expected to trend toward the lower end of the range as increased volumes of Chelopech concentrate are processed by third-party smelters.

1. Cost of sales per tonne of ore processed and cost of sales per ounce of gold sold are supplementary financial measures, representing Chelopech cost of sales divided by the volume of ore processed and the payable gold in concentrate sold, respectively. Cash cost per tonne of ore processed and AISC per ounce of gold sold are Non-GAAP ratios. These cash cost and AISC measures have no standardized meanings under International Financial Reporting Standards ("IFRS") and may not be comparable to similar measures presented by other companies. Refer to the "Non-GAAP Financial Measures" section contained in the Company's Management's Discussion and Analysis (the "MD&A") for the year ended December 31, 2021 commencing at page 55, which is available on the Company's website at www.dundeeprecious.com and has been filed on the SEDAR site at www.sedar.com, for a detailed description, and in the case of historical measures, a reconciliation of each of these measures to the most directly comparable measure under IFRS.

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

DPM continues to focus on extending Chelopech's mine life through its successful in-mine exploration program and a growing brownfield exploration program, which for 2022 includes:

• Approximately 44,000 metres of in-mine drilling for Mineral Resource development; and
• Approximately 50,000 metres of brownfield exploration, primarily concentrated on near mine exploration drilling related to the Sveta Petka commercial discovery application, as well as drilling at Sharlo Dere and other near-mine targets in the mining concession area.

The Company's application for a one-year extension to the Sveta Petka exploration licence, which surrounds the Chelopech mine, was approved in November 2021, allowing DPM to commence work related to the commercial discovery phase. Permitting for a 50,000-metre drilling campaign with a focus on Sveta Petka has been completed. Drilling has commenced and is expected to be completed in 2022.

In line with the Company's 2022 guidance, exploration spending is expected to be $16 to $19 million, of which approximately 65% has been allocated to support the brownfield exploration program at Chelopech.

Additional Updates to DPM's Mineral Reserve and Mineral Resource Estimates

The Mineral Resource and Mineral Reserve estimates for DPM's Ada Tepe mine in Bulgaria, disclosed in DPM's 2021 Annual Information Form ("AIF") dated March 31, 2022, have been depleted to account for production up until December 31, 2021. An updated Mineral Reserve and Mineral Resource estimate for Ada Tepe is scheduled to be completed in the second half of 2022.

The Mineral Resource and Mineral Reserve estimates for the Timok gold project in Serbia and the Loma Larga gold project in Ecuador remain unchanged from the estimates previously reported in the technical reports with effective dates of February 23, 2021, and April 8, 2020 (reissued by DPM on November 29, 2021), respectively.

Cautionary Note to United States Investors Concerning Estimates of Mineral Reserves and Mineral Resources

The Mineral Reserve and Mineral Resource estimates presented in this news release have been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. Canadian reporting requirements for disclosure of mineral properties are governed by NI 43-101.

The United States Securities and Exchange Commission ("SEC") adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities Exchange Act of 1934, as amended. These amendments became effective February 25, 2019 (the "SEC Modernization Rules") with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical disclosure requirements for mining issuers that were included in SEC Industry Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources". In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") - Definition Standards adopted by CIM Council on May 10, 2014 (the "CIM Definition Standards"), incorporated by reference in NI 43-101.

Readers are cautioned that while the above terms are "substantially similar" to the corresponding CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any Mineral Reserves or Mineral Resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

Readers are also cautioned that while the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", it should not be assumed that any part or all of the mineralization in these categories will ever be converted into a higher category of Mineral Resources or into Mineral Reserves. Mineralization described using these terms has a greater amount of uncertainty as to their existence and feasibility than mineralization that has been characterized as reserves. Accordingly, readers are cautioned not to assume that any "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, readers are also cautioned not to assume that all or any part of the "inferred mineral resources" exist. In accordance with Canadian securities laws, estimates of "inferred mineral resources" cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.

For the above reasons, information contained in this news release containing descriptions of the Company's mineral deposits may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
