Silverco Mining Ltd. Announces Results of Preliminary Economic Assessment for the Restart of its Cusi Mine in Chihuahua, Mexico Silverco Mining Ltd. announced the results of an independent Preliminary Economic Assessment (PEA) for the restart of its 100%-owned Cusi Mine located in Chihuahua, Mexico. After-tax NPV (5%) of USD 104.1 million, IRR of 94.8% and a payback period of 0.9-years at base case average silver price of USD 44.58/ounce. After-tax NPV (5%) of USD 312.2 million, IRR of 186.9% and a payback period of 0.5-years at the upside case of USD 75.00/ounce. Average annual production of approximately 2.5 million ounces silver equivalent (AgEq) (2028-2033) with approximately 90% revenue from silver. Life-of-mine AISC of USD 26.75 per payable ounce AgEq. Initial capital of only USD 19.2 million, delivering 5.4x after-tax NPV/to initial capital at base case metal prices. Restart of processing targeted for late 2026 with full ramp-up by mid-2027. 30,000 metre surface and underground drill program underway targeting infill, resource growth and mine life extension. Early restart work is underway at the mine and mill and discussions are underway to select an underground contractor. The PEA outlines a low-capital restart of an existing underground mine with an initial approximately nine-year mine life and steady-state throughput of 1,200 tonnes per day. Production is scheduled to begin in late 2026, with full ramp-up by mid-2027, and average annual output of 2.47 million ounces AgEq produced from 2028-2033. The Cusi Project's economic profile is defined by its substantial leverage to silver prices, with 88% of the projected life-of-mine Net Smelter Return (NSR) revenue generated directly from silver production. The remaining 12% of the NSR revenue is comprised of by-product metals, including lead (8%), gold (3%), and zinc (1%), as calculated using the PEA's metallurgical recovery, metal price assumptions, and payabilities. Mining activities will focus on three primary zones: Promontorio, San Miguel, and Eduwiges. Initial production will prioritize the Promontorio zone to leverage extensive existing underground infrastructure and advanced mine development. Development of the newly defined San Miguel zone is slated to proceed concurrently, with a target to be fully ramped up by the end of the First Half 2027. The extraction will utilize conventional sublevel long-hole open stoping in a retreat strategy, performed by specialized contract miners. To optimize grade delivery, the Company will employ a stockpiling strategy for lower-grade material. The Cusi underground mine is located approximately 120 kilometre West from the city of Chihuahua and 20 km south of Cuauhtemoc city. The location allows for access to an experienced labour pool with a population of more than one million people. Ore will be transported from the mine via 30-tonne highway trucks to the Company's existing 1,200 tpd processing facility, located approximately 40 km from the mining areas. The mill utilizes a conventional comminution and flotation circuit designed to produce a high-value bulk lead-silver concentrate. The project currently maintains constructed tailings storage capacity for the first 12 months of production. Permitting is already in place for additional capacity required by the end of 2027.

Restart Study & Engineering. Silverco has engaged JDS to lead the Cusi Restart Study. The study is leveraging the updated Mineral Resource Estimate (MRE) and will define the economic and operational parameters required for a resumption of mining. The Company remains on track to deliver the results of the Restart Study in late First Quarter 2026. Metallurgical Optimization. Exploration and 2026 Season. Silverco continues to evaluate results from its successful 2025 exploration program. To date, the Company has released assays for 26 holes, with results from an additional 20 holes expected to be received and published in early First Quarter 2026. The remainder of the program tested for extensions along strike at San Miguel, and for confirmation of downthrown mineralization at San Juan. The Cusi Property boasts excellent infrastructure, including paved highway access and connection to the national power grid. The Cusi Property hosts multiple historical Ag-Au-Pb-Zn producing mines each developed along multiple vein structures. The Cusi property hosts several significant exploration targets, including the extension of a newly identified downthrown mineralized geological block and additional potential through claim consolidation. Such factors include, without limitation: exploration, development and operating risks (including drilling, sampling, assaying, interpretation and modeling uncertainties; variability of mineralization; representativity of samples; true-width estimation; metallurgical variability; water management; geotechnical and ground conditions); risks inherent in estimating or converting mineral resources; the absence of current mineral reserves at the Cusi Property; that AgEq is a reporting metric only and does not imply economic recoverability; permitting, licensing and regulatory risks in Mexico (including changes in mining, environmental, labour, water, land access and related regimes); community relations, social licence and stakeholder engagement risks; title, surface rights, access and environmental liability risks; health, safety and security risks; commodity price and FX volatility (silver, gold, lead, zinc; MXN/CAD/USD); cost inflation, supply-chain disruptions and contractor availability; political and macro conditions.

New major risk - Negative shareholders equity The company has negative equity. Total equity: -CA$398k This is considered a major risk. Being in negative equity means that the company's liabilities exceed its assets, meaning it owes more to creditors than it has in owned assets. While this doesn't mean the company is about to collapse, in the long-term, this is unsustainable. The company may have issues meeting financial obligations, is at risk of becoming insolvent and may have difficulty raising capital, especially more debt, if needed. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-CA$2.6m free cash flow). Shares are highly illiquid. Negative equity (-CA$398k). Revenue is less than US$1m. Bekanntmachung • Nov 28
Silverco Mining Ltd. Reports the Third Batch of Assay Results from its 15,000 Metre 2025 Diamond Drill Program at the 100%-Owned Cusi Property Silverco Mining Ltd. reported the third batch of assay results from its 15,000 metre 2025 diamond drill program at the Company's 100%-owned Cusi Property ("Cusi"), located approximately 90 kilometres northwest of First Majestic's Los Gatos Mine in Chihuahua, Mexico. The latest drilling at the San Miguel zone has successfully identified a series of steeply-dipping, closely spaced parallel veins, returning mineralized widths significantly exceeding historical averages for the district. While previous drilling had encountered a single broad vein among multiple other veins across the San Miguel system, these latest results confirm a significant evolution in the geological model: multiple parallel structures are now simultaneously exhibiting broad widths and high grades. Hole CU-25-37 intersected a cluster of mineralization including 12.4 metres grading 273 g/t AgEq, 8.8 metres grading 319 g/tAgEq, and 8.8 metres grading 172 g/t AgEq. This transition from a wide structure to a swarm of wide, parallel zones, spaced favorably at around 10 metres apart, creates a compelling case for high-productivity bulk mining methods distinct from the narrow-vein operations historically seen at Cusi. All of the assays reported in this news release were received past the cut-o date for inclusion in the upcoming Mineral Resource Estimate ("MRE") update scheduled for release in December. These holes and the remainder of 2025 drilling will be included in a subsequent MRE update in 2026. The system remains wide open, suggesting the scale of this zone could continue to grow-- Details of the 2025 Drill Program. The 2025 program consists of 15,000 metres of surface diamond drilling. The program is approximately two thirds complete. Vein widths are variable, ranging from less than 1.0m to exceeding 5.0m, and are steeply dipping at 70-80o. Detailed drill results, along with notable assays results are provided in tables 1 and 2. Significant Assay Results from the 2025 Drill Program. Metallurgical recoveries used in this release are based on historical operational results on the Cusi project. All diamond drill core from the 2025 program at the Cusi Project was logged, photographed, and sawn in half using a diamond blade core saw. The Cusi Property hosts multiple historical Ag-Au-Pb-Zn producing mines each developed along multiple vein structures. Bekanntmachung • Nov 12
