Denarius Metals Announces Conversion of 73% of Resources to the Indicated Category in Its Updated Mineral Resource Estimate for Its Lomero Project in Spain
Toronto, September 18, 2023 - Denarius Metals Corp. (TSXV: DSLV) (OTCQX: DNRSF) ("Denarius Metals" or the "Company") announced today that it has completed an updated Mineral Resource estimate ("MRE") for its 100%-owned Lomero Project in Spain prepared by SRK Consulting (U.S.), Inc. ("SRK") in accordance with the Canadian Institute of Mining Metallurgy and Petroleum ("CIM") Definition Standards incorporated by reference in National Instrument 43-101 ("NI 43-101") with an effective date of July 31, 2023.
Highlights of the updated MRE include:
Indicated Mineral Resources comprise 7.73 Mt at 0.66% Cu, 1.03% Zn, 0.46% Pb, 25 g/t Ag and 2.27 g/t Au (1.91% CuEq) containing an estimated 51 kt Cu, 80 kt Zn, 36 kt Pb, 6.1 Moz Ag and 0.6 Moz Au.
Inferred Mineral Resources comprise 3.45 Mt at 0.29% Cu, 1.18% Zn, 0.53% Pb, 22 g/t Ag and 1.86 g/t Au (1.46% CuEq) containing an estimated 10 kt Cu, 41 kt Zn, 18 kt Pb, 2.5 Moz Ag and 0.2 Moz Au.
The updated MRE effective as of July 31, 2023 has been prepared following the completion of the Company's Phase 2 and Phase 3 infill and validation drilling campaigns carried out from October 2022 through July 2023. The current geological model and updated MRE for the Lomero-Poyatos deposit include the results obtained from a total of 146 holes representing 44,228 meters of drilling completed to date by the Company plus another 55 historical holes drilled by CMR representing 10,053 meters.
The most significant change in the updated MRE compared to the initial MRE prepared effective July 19, 2022 (after completion of the Phase 1 drilling campaign) has been an increase in the confidence in the geological model to include Indicated Mineral Resources. The Phase 2 and Phase 3 drilling campaigns have successfully converted approximately 73% of the initial inferred MRE to the Indicated Mineral Resources category. There have also been gains in both tonnage and grades for all metals reported since the initial MRE.
Serafino Iacono, Executive Chairman and CEO of Denarius, commented, "Our Phase 2 and Phase 3 drilling campaigns have successfully increased our confidence in the geological model for our Lomero Project, including an upgrade of resources and an increase in tonnages and grades, as demonstrated by the updated MRE reported today. Drilling to date has focused on the historical Lomero-Poyatos deposit where we have identified mineralization over a strike of over 1 km and with a vertical extension of 400 meters. The updated MRE provides us with a solid foundation to commence the next stage of work on a preliminary economic assessment ("PEA") for the project. In addition, we continue to have significant exploration upside at our Lomero Project. Later this year, we expect to commence a 6,000 meters greenfield exploration drill program targeting the Las Merinas and Alianza areas located to the south and to the north of the shear zone that hosts the Lomero-Poyatos deposit with the objective of increasing the tonnage in the next MRE update. Earlier this year we reported that we have been granted an investigation permit for Palomarejo, a 151-hectare area which is adjacent to and on strike with the Lomero-Poyatos deposit. We expect to start our drilling campaign in this area as part of our 2024 exploration program. With our Zancudo Project in Colombia advancing toward the commencement of production in 2024, a successful drilling campaign in 2023 as recently reported at the Toral Project in Northern Spain and this latest announcement regarding the updated MRE at our Lomero Project, we are very pleased to see solid momentum in the catalysts for each of our three core projects to create value for our shareholders."
The updated Mineral Resource for the Lomero Project with an effective date of July 31, 2023 is shown in Table 1 below. The Mineral Resources have been reported based on Copper Equivalent ("CuEq") with the key assumptions included in the table. In order to meet "reasonable prospects for eventual economic extraction" requirement, the Lomero deposit has been deemed amenable to both open pit and underground mining (for the remaining material which has displayed continuity above the defined cut-off grades), with the cut-off grades of 0.4% CuEq for open pit resources and 0.6% CuEq for underground resources established using benchmarked costs taken from similar deposits within the Iberian Pyrite Belt and metallurgical recoveries based on the outcomes of the initial metallurgical test work completed by the Company between 2022 and 2023.

|Average Value||Material Content||Metal|
(1) Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All ﬁgures have been rounded to reﬂect the relative accuracy of the estimates. Gold, silver, copper, lead and zinc assays were capped where appropriate. It is assumed based on regional benchmarking that all the elements included in the CuEq calculation have a reasonable potential to be recovered and sold.
(2) The CuEq calculation has been defined using the following formula:
CuEq =((Au*21.38)+(Ag*0.42)+(Cu*69.45)+(Pb*12.68)+(Zn*25.46)/99.21)/ Cu Recovery
(3) Mineral resources are reported using an assumed CuEq cut-off grade based on metal price assumptions*, variable metallurgical recovery assumptions**, mining costs, processing costs, general and administrative (G&A) costs and variable NSR factors***. Mining, processing and G&A costs total US$31/t for Open Pit Mining and US$45/t for Underground Mining which includes assumptions for prices, recoveries and payabilities. The CuEq cut-off grade 0.4% CuEq (OP) and 0.6% CuEq (UG) is calculated by dividing the costs by the Cu Factor and recoveries.
(*) Metal price assumptions considered for the calculation of Metal Equivalent grades are: Gold (US$/oz 1,900.00), Silver (US$/oz 24.0), Copper (US$/lb 4.50), Lead (US$/lb 1.15) and Zinc (US$/lb 1.50)
(**) Cut-off grade calculations assume variable metallurgical recoveries as a function of grade and relative metal distribution. Average metallurgical recoveries are: Gold (35%), Silver (55%), Copper (70%), Lead (50%) and Zinc (77%).
(***) Cut-off grade calculations and metal equivalencies assume variable CuEq factors as a function of smelting, transportation costs and royalties (3%).
(3) Open pit (OP) mineral resources are constrained within NPV optimized pits which SRK based on assumed mining costs defined.
(4) Underground (UG) mineral resources represent all material below the proposed limiting pit shell which have been confirmed visually to form contiguous units with a minimum width of 2.5 x 2.5 x 1.25m
(5) MS = Massive Sulphides; SMS = Semi-Massive Sulphides.
(6) The mineral resources were estimated by Benjamin Parsons, BSc , MSc Geology, MAusIMM (CP) #222568 of SRK, a Qualified Person.

Cautionary Statement on Mineral Resources
Mineral resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. In particular, the quantity and grade of reported inferred mineral resources are uncertain in nature and there is insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource in all cases. It is uncertain in all cases whether further exploration will result in upgrading the inferred mineral resources to an indicated or measured mineral resource category.
