Denarius Metals Announces Positive Pea Results For Its 100%-owned Zancudo Project In Colombia

Denarius Metals Corp. (TSXV: DSLV) (OTCQX: DNRSF) ("Denarius Metals" or the "Company") announced today the results of a Preliminary Economic Assessment ("PEA") for its 100%-owned Zancudo Project, which includes the historic producing underground Independencia Mine, located in the Municipality of Titiribi, Department of Antioquia, Republic of Colombia, approximately 30km southwest of Medellin. The PEA was prepared 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 March 19, 2026. All figures contained herein are expressed in United States dollars ("USD"), except as otherwise stated.

Serafino Iacono, Executive Chairman of Denarius Metals, commented, "The updated PEA reaffirms the positive economic results from our underground mining operation at our Zancudo Project, generating production and cash flow from a long-life asset yielding attractive returns for our shareholders in a robust precious metals market. We are already in production at Zancudo and our plant construction and mine development activities are proceeding on schedule. The updated PEA, based on the Mineral Resource estimate ("MRE") announced by the Company on November 3, 2025, envisions an 11-year mine life over which the Company expects to generate revenue of approximately $2.0 billion and pre-tax gross profit of approximately $723 million from the sale of approximately 466,000 payable ounces of gold and 2.2 million payable ounces of silver at a life-of-mine ("LOM") average all-in sustaining cost ("AISC") of $2,482 per ounce of gold. The Zancudo deposit remains open for further expansion in all directions and we are commencing the next 15,000 meters drilling program in early April".

Highlights of the Zancudo Project PEA

• The Zancudo Project PEA is based on an updated MRE, with an effective date of October 31, 2025 comprising 1.0 million tonnes grading 6.9 g/t gold and 84 g/t silver totaling 217,000 ounces of gold and 2.7 million ounces of silver in the Indicated Resources category and 4.6 million tonnes grading 5.6 g/t gold and 84 g/t silver totaling 832,000 ounces of gold and 12.5 million ounces of silver in the Inferred Resources category.
• Over the approximately 11-year mine life, production from the mining and processing of approximately 3.3 million tonnes of material containing 619,000 gold ounces and 7.2 million silver ounces is expected to produce 466,000 payable gold ounces and 2.2 million payable silver ounces through the sale of high-grade gold-silver concentrates to Trafigura Pte. Ltd. ("Trafigura") under a long-term offtake contract.
• Remaining initial capital costs of $11.0 million, of which $3.4 million will be funded by proceeds from the Trafigura Prepayment Facility.
• AISC of $2,482 per ounce of payable gold on a by-product credit basis based on a long-term gold price of $4,000 per ounce. Approximately 50% of the Zancudo Project's operating costs, mainly its mine contractor fees and its royalties, fluctuate with changes in the price of gold.
• At long-term gold and silver prices of $4,000 per ounce and $50 per ounce, respectively, total LOM undiscounted after-tax project cash flow amounts to $452 million. At a 5% discount rate, the net present value of the total LOM after-tax project cash flow amounts to $324 million.
• The Zancudo Project has an after-tax internal rate of return of 558% and payback in one year.

Please see "Cautionary Statement on PEA and Use of Inferred Resources" below for the limitations, explanations and cautionary language on the use of the PEA.

Capital Costs

The estimated remaining capital costs to bring the Zancudo Project into commercial operation in 2026 are based on an underground mining operation utilizing local contract mining and a processing plant that will be installed under a "build and operate" arrangement with a local civil engineering and industrial construction services firm (the "Plant Contractor"). The local mine contractor is responsible for certain capital development and all operating development within the underground mine and will be compensated for such work through its mine operating contract with the Company.

The remaining initial capital expenditures for the construction period are estimated at $11.0 million, as set out in Table 2 below. An additional $16.0 million is estimated for sustaining capital, of which $13.5 million is associated with capital development in the Brisas area beyond the initial construction period and $2.5 million corresponds to the 15,000 meters exploration drilling program commencing in April and being carried out through 2026.

Capital cost estimates are based on industry standards. In the case of the remaining initial capital costs, the amounts are based on actual contracts and commitments or were developed using quotes provided by contractors and specialists experienced in mining development in Colombia.

Table 2: Capital Costs

Mining

The minable resource is accessed utilizing existing workings, new planned development including a new portal, ventilation/secondary escapeways, and rock handling systems. Nominal dimensions of the waste development is sized to accommodate a transition into mechanized mining. The minable resource will be extracted utilizing three mining methods, long hole open stoping and cut and fill for the steeply dipping veins and traditional room and pillar for the flat-lying mineralization. Most of the waste is planned to remain underground reducing the requirement for surface waste facilities. Mining costs in the PEA are based on an agreement arranged between the Company and a local contract miner wherein the contractor will be paid for their services at a rate tied to actual gold production and spot gold prices.

Processing

The Company is constructing a 1,000 tonnes per day processing plant that will produce a high-grade Au-Ag concentrate that will be shipped to a local port in Colombia and sold under a long-term offtake contract with Trafigura.

The Zancudo process scheme includes three-stage crushing followed by conventional grinding and product slurry conditioning. Processing of the conditioned slurry product will be followed by industry typical bulk sulfide flotation to produce a bulk sulfide concentrate for the recovery of gold and silver. The flotation concentrate will be thickened, filtered and prepared for shipment. Flotation tailings will be thickened and filtered for disposal as dry-stacked material in the tailings storage facility ("TSF").

Site preparations for the new processing plant have made good progress to date. Civil works will commence in the second quarter of 2026 followed by installation of the plant equipment and construction of the dry-stack TSF over the summer months. Commissioning is expected to take place in the third quarter this year.

The Company has recently engaged a Plant Contractor with extensive experience in extractive industries projects to build and then operate the new processing plant on a contract basis. The Plant Contractor has agreed to finance their fees for the plant installation services, valued at $3 million, through the issuance of 2,529,000 common shares of the Company at a price of CA$0.76 per share, equivalent to $1.4 million, and the balance to be settled through the processing fees to be paid to the Plant Contractor by the Company during the operation of the plant. Processing costs in the PEA are based on the rates specified in the agreement with the Plant Contractor for the comprehensive operation and maintenance of the plant, including labor, reagents, power, maintenance and overhead costs associated with the crushing, grinding, concentration and filtration areas.

Cautionary Statement on PEA and Use of Inferred Resources

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted to mineral reserves. The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. The PEA is based on mine plan tonnages and mill feed schedules, derived from the MRE. The PEA was prepared to allow the Company to update its evaluation of the economic viability of underground mining at the existing Independencia Mine and is subject to the assumptions and qualifications expressed in this news release and those that immediately follow. Mineral resources are assumed to be mined underground. The cutoff grade in the MRE of 3.25 g/t AuEq considered the following factors: (i) metal selling prices for gold at $2,400/oz and silver at $28/oz, (ii) recoveries of 85% for gold and 87% for silver, (iii) royalties of 6.7% and (iv) costs including mining of $105.00/t, processing of $42.00/t, general and administrative (G&A) and off-site realization (TCRC) of $21.00/t. Gold equivalent grade ("AuEq") was calculated by the formula "Au *Au Recovery (85%) * AuPrice + Ag *Ag Recovery (87%) * AgPrice)) / (Au Recovery (85%) *Au Price".
