TORONTO, March 30, 2023 (GLOBE NEWSWIRE) -- Dundee Precious Metals Inc. (TSX: DPM) (“DPM” or “the Company”) is pleased to provide an updated Mineral Resource and Mineral Reserve estimate for the Chelopech mine in Bulgaria.

Highlights

• Mine life extended to 2031: Proven and Probable Mineral Reserves of 1.6 million ounces (“Moz.”) of gold and 312 million pounds (“Mlbs.”) of copper supports a mine life that now extends to 2031. In 2022, DPM successfully added approximately 1.1 million tonnes (“Mt”) to Mineral Reserves, replacing about half of its 2022 production depletion of 2.1 Mt.
• Growth of Measured and Indicated Mineral Resource base: Total Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, of 1.3 Moz. of gold and 281 Mlbs. of copper add further potential to extend mine life.
• Additional potential with in-mine and brownfield exploration: Significant drilling program planned for 2023, including 44,000 metres of in-mine drilling for Mineral Resource development, and 50,000 metres of brownfield drilling, focused on infill drilling at the Sharlo Dere prospect and conceptual targets on the mine concession and Brevene exploration licence.

“The updated Mineral Reserve estimate demonstrates our consistent track record of replacing Mineral Reserves at Chelopech,” said David Rae, President and Chief Executive Officer of Dundee Precious Metals.

“With mining now expected to extend into 2031, a strong 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 Reserve and Resource Estimate

The 2022 Mineral Resource and Mineral Reserve estimate is based on a net smelter return (“NSR”) equation that informs a profitability indicator that considers, among other things, metal price, metallurgical recoveries, treatment charges and market forecasts.

The updated Proven and Probable Mineral Reserves at Chelopech of 1.55 Moz. of gold and 311.5 Mlbs. of copper support a nine-year mine life that extends to 2031, excluding expected further conversions of existing Mineral Resources and potential additional exploration success.

The updated Mineral Reserves estimate is shown below and is effective as of December 31, 2022:

Chelopech Proven and Probable Mineral Reserve Estimate (As at December 31, 2022)
Ore Type	Reserve Classification	Tonnes (Mt)	Grades			Metal Content
			Au (g/t)	Ag (g/t)	Cu (%)	Au (Moz.)	Ag (Moz.)	Cu (Mlbs.)

Total		18.2	2.64	8.2	0.77	1.55	4.78	311.5

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 Reserves have been depleted for mining as of December 31, 2022.
3. The Inferred Mineral Resources do not contribute to the financial performance of the project and are treated in the same way as waste.
4. The reference point at which the Mineral Reserves are defined is where the ore is delivered to the crusher.
5. Long term metal prices assumed for the evaluation of the Mineral Reserves are $1,500/oz. for gold, $17.00/oz. for silver, and $3.25/lb. for copper.
6. Mineral Reserves are based on a net smelter return-less-costs cut-off value of $0/t. The total cost applied was $55/t which is a sum of operational costs of approximately $50/t 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 (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 for the average head grade. The simplified formula for general ore which comprises 97% of the Mineral Reserve is NSR $/t = 26.091 x Cu% + 0.196 x Ag_g//t + 30.773 x Au_g/t.
8. 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 8.1% for unplanned ore loss and 7.3% for unplanned dilution.
9. 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.
10. All stopes have been verified that they are profitable after considering the cost of capital development.
11. 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 expiry of the mining concession contract. It is the opinion of DPM that the mining permit will be extended.
12. The Proven Mineral Reserve includes broken stocks of 58 kt at 2.54 g/t Au, 5.4 g/t Ag and 0.64% Cu as well as stockpiles of 5 kt at 3.74 g/t Au, 5.0 g/t Ag and 0.75% Cu.
13. Sum of individual table values may not equal due to rounding.

A three-dimensional block model using 10 metres (E) x 10 metres (N) x 10 metres (RL) cell dimensions was created. This model honours wireframe volumes and was based on geological interpretations of the mineralization. Grade estimation of economic elements of interest, namely copper, gold and silver were completed, with the addition of potentially deleterious elements (sulphur and arsenic) using ordinary kriging. Block tonnage was estimated from the material in-situ dry bulk density values by using ordinary kriging where adequate density samples were available, and from the positive relationship to sulphur grade where density sampling was limited.

The Mineral Resource estimate has been depleted by all mining and development work completed as of December 31, 2022 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, increased by 2.7Mt compared with 2021, as a result of changes to NSR parameters, grade estimation and interpretation, partly offset by conversion to Mineral Reserves.

The Mineral Resource estimate is shown below and is effective as at December 31, 2022:

Chelopech Mineral Resource Estimate, exclusive of Mineral Reserves (As at December 31, 2022)
Classification	Tonnes	Gold		Silver		Copper
	(Mt)	Grade (g/t)	Moz.	Grade (g/t)	Moz.	Grade (%)	Mlbs.
Measured	8.5	2.54	0.695	8.57	2.344	0.83	156
Indicated	7.9	2.39	0.609	10.06	2.566	0.71	125
Total Measured & Indicated	16.4	2.47	1.303	9.29	4.909	0.78	281
Inferred	4.4	1.93	0.276	8.57	1.225	0.70	69

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. Tonnages are rounded to the nearest 0.1 million tonnes to reflect that this is an estimate.
3. Metal content is rounded to the nearest 1 thousand ounces or 1 million pounds to reflect that this is an estimate.
4. The Mineral Resources are reported exclusive of Mineral Reserves.
5. Metal prices assumed for the evaluation of the Mineral Resources are $1,700/oz. for gold, $17.00/oz. for silver, and $3.75/lb. for copper.
6. Mineral Resources are based on a NSR less costs cut-off value of US$0/t in support of reasonable prospects of eventual economic extraction. The total cost applied was approximately $55/t which is a sum of operational costs of approximately $50/t and sustaining capital of approximately $5/t.
7. All blocks include a complex NSR (Net Smelter Return) formula that differs for the three ore types. The NSR formula utilises long term metal price, metallurgical recoveries, payability terms. treatment charges, refining charges, penalty charges, concentrate transport costs, and royalties. For clarity of understanding of ore value, a simplified formula is presented here for the Measured and Indicated Resource where NSR US$/t = 33.870 x Cu % + 0.171 x Ag g/t + 37.937 x Au g/t.

Life of Mine Plan

The table below shows the updated LOM plan, reflecting the updated Mineral Reserve estimate.

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

DPM continues to aggressively focus on extending Chelopech’s mine life through its successful in-mine exploration program and a growing brownfield exploration program, which for 2023 includes:

• Approximately 44,000 metres of in-mine drilling for Mineral Resource development with particular focus on the upper levels of Blocks 103, 150, 151 and 153, Target 11 and Target 147 zones (see Figure 1).
• Approximately 50,000 metres of brownfield exploration, aiming to test conceptual targets on the Brevene exploration licence, which surrounds the Sveta Petka exploration licence, as well as in the Chelopech mine concession (see Figure 1).

The brownfield exploration program is designed to follow-up on conceptual targets on the mine concession, including testing for deeper and lateral extensions of the Chelopech deposit, as well as targets on the Brevene exploration licence.

A focused infill drilling program is planned at Sharlo Dere, which is located on the east flank of the mine. The planned drilling will be used to potentially support the inclusion of this prospect within subsequent Mineral Resource estimates for the Chelopech mine. Additionally, extensional drilling will test the Target 11 and Sharlo Dere Deeps targets, both of which are under-explored and demonstrate strong potential to host additional mineral resources.

In March 2023, the Company filed a Commercial Discovery application with the Bulgarian authorities for the Sveta Petka exploration licence, which includes the Wedge, West Shaft, Krasta and Petrovden prospects. The Sveta Petka exploration licence is expected to be registered as a Commercial Discovery by the end of 2023 and subsequent to that, the Company intends to apply for concession rights in 2024.

In line with DPM’s 2023 guidance, the Company has budgeted between $5 million to $6 million on in-mine exploration activities at Chelopech, and $5 million to $6 million for brownfields exploration activities.

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.
