Silverco Mobilizes Underground Mining Contractors at Cusi PropertyJune 25, 2026 6:30 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Silverco Mining Ltd. (TSXV: SICO) ("Silverco" or the "Company") is pleased to report that underground contractors have begun mobilization at its 100% owned Cusi Property ("Cusi") in Chihuahua, Mexico. Silverco has engaged Mafrissa Transportes y Maquinaria S.A. de C.V ("Mafrissa") and Rencer Servicio a la Mineria, S.A. de C.V. ("Rencer") to provide development and production mining activities.Mark Ayranto, CEO of Silverco, commented:"Mobilization of contractors is an important milestone in our Cusi restart plan. The two contractors now active at Cusi are well-established and experienced local firms with extensive underground mining experience. With this work and the mill rehabilitation work underway, we remain on schedule to produce first concentrate in Q4 2026 and exit 2026 with two producing silver mines in Mexico. We look forward to providing additional updates from both Cusi and La Negra over the coming weeks with significant catalysts expected through H2 2026 relating to restart and productivity improvement activities at Cusi and La Negra respectively, and sizable exploration programs at both projects." Underground development will begin at Cusi's two primary mining zones, managed separately by each contractor, Promontorio and San Miguel, with first ore from Promontorio expected in late Q3 2026. Promontorio was mined as recently as 2023 and has been completely dewatered and rehabilitated by Silverco with underground drilling now active and having recently intersected new mineralization within the footprint of planned mine development. San Miguel is one of the most prospective zones at Cusi, but has not seen modern mining, and as such a new portal and ramp will be developed, with first ore from this zone expected to ramp up over H1 2027. Mafrissa is a Chihuahua based mining contractor that focuses on underground development, mining support services, heavy equipment rental, and material haulage, and has been contracted by numerous large-scale mining operations in Mexico. Mafrissa is headquartered in Cuauhtémoc, less than 20 kilometres from the Cusi Property. Rencer is a local mining contractor based in Cuauhtémoc who was previously contracted at Cusi, allowing for a strong understanding of the mine.Planned Cusi Restart As outlined in an April 13, 2026 news release, the Cusi project offers compelling economics based on the results from the 2026 PEA1 which outlined a project with average annual silver equivalent production of approximately 2.5 Moz at site all-in-sustaining costs of US$26.75/oz payable AgEq from 2028 to 2032, once fully ramped up. At an average base case silver price of US$44.58/oz, the after-tax NPV of Cusi is US$104.1 M with an IRR of 94.8% and a payback period of 0.9 years, and at US$75.00/oz, the after-tax NPV is US$312.2 M with an IRR of 186.9% and a payback period of 0.5 years. With 90% of the revenue generated from silver and low upfront capital of US$19.2 million, Cusi represents a unique opportunity in the silver industry and for Silverco to advance its vision of becoming a 10 million ounce per year silver equivalent producer within three years.

Silverco Mining Intersects 1,712 g/t AgEq over 1.4 metres Adjacent to Near-Term Planned Stopes at CusiJune 16, 2026 6:30 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - June 16, 2026) - Silverco Mining Ltd. (TSXV: SICO) ("Silverco" or the "Company") is pleased to report initial underground assay results from its 100%-owned Cusi Property ("Cusi") in Chihuahua, Mexico. These results are part of the Company's 2026 30,000 metre diamond drill program that is focused on infill, expansion, and exploration at high potential targets across the property.Initial underground drilling at Promontorio, the first of three planned mining zones at Cusi, has been focused on infilling areas that are planned for mining in the first year of operations. These areas have been identified as highly prospective but required additional drilling to be included in the resource and mine plan.Mark Ayranto, CEO of Silverco, commented:"We are encouraged by the initial results from our 2026 Cusi drill program which have identified additional mineralization within the footprint of the first year of the Preliminary Economic Assessment ("PEA")1 mine plan. With grades and widths consistent with our resource, these results highlight the opportunity to lower initial underground development, bring more tonnage forward and enhance project economics from the US$312 million after-tax NPV outlined in the PEA at silver prices in line with current levels2. With dewatering and underground rehabilitation complete in Q1 2026, this is our first underground drilling at Promontorio, and the results reinforce our confidence in the vein system as we move toward a restart in H2 2026, with mobilization of underground contractors and commencement of development planned in the coming weeks."The initial results from the 2026 Cusi exploration program are from the Promontorio East veins, an area that boasts exceptional undiluted high-grade material with Measured and Indicated Resource grades of 295 g/t AgEq and Inferred Resource grades of 301 g/t AgEq. This infill drilling is specifically aimed at optimizing mine planning and targeting near-term resource expansion that can be integrated into the short-term mine plan, creating opportunities to enhance economics through reduced development requirements or increased resources available in the areas of planned development.These results were drilled within the first 50 vertical metres of planned development and fall within a 150 metre by 250 metre area of Promontorio that required infilling and was not previously captured in the PEA. Highlights from the first four drill holes in this area include: UGCU-26-01 - 428 g/t AgEq over 1.1 metresUGCU-26-02 - 1,712 g/t AgEq over 1.4 metresUGCU-26-03 - 303 g/t AgEq over 8.3 metresUGCU-26-04 - 160 g/t AgEq over 3.2 metresDetails of the 2026 Cusi Exploration ProgramThe 2026 Cusi exploration program includes 30,000 metres of diamond drilling, split between underground (10,000 metres) and surface drilling (20,000 metres). The program's primary goals are to:(1) Infill prospective areas which are targeted for mining early in the planned restart at Promontorio and San Miguel;
(2) Expand known areas of mineralization at San Miguel
(3) Explore prospective targets at San Miguel, Eduwiges, and San Juan. With success, this program will enhance mine planning for the initial years of the planned restart and identify opportunities to increase mineral resources in these areas and in new target areas as part of a planned H1 2027 Cusi resource update.Figure 1: 2026 Drill Program Collar LocationsTo view an enhanced version of this graphic, please visit:

This planned restart is supported by the results from the PEA1 which outlined a project with average annual silver equivalent production of 2.47 Moz at site all-in-sustaining costs of US$26.75/oz payable AgEq from 2028 to 2032, once fully ramped up. At an average base case silver price of US$44.58/oz the after-tax NPV of Cusi, as defined by the PEA1, is US$104.1 M with an IRR of 94.8% and a payback period of 0.9-year payback, and at US$75.00/oz, the after-tax NPV is US$312.2 M with an IRR of 186.9% and a payback period of 0.5-year payback. With close to 90% of the revenue generated from silver and low upfront capital of US$19.2 million, Cusi represents a unique opportunity in the silver industry and for Silverco to advance its vision of becoming a 10 million ounce per year silver equivalent producer within three years. Underground rehabilitation work at Cusi is complete and the Company expects to begin mobilizing contractors underground by the end of Q2 2026 with initial concentrate production planned for late 2026. Quality Assurance/Quality Control and Sampling ProceduresAll diamond drill core from the 2026 program at the Cusi Project is logged, photographed, and sawn in half using a diamond blade core saw. One half of the core is submitted for geochemical analysis, while the other half is retained in secure storage for reference. Sampling intervals are determined based on geological boundaries and typically range from 0.3- 1.5 metres. Control samples comprise approximately 18% of all samples submitted, including certified reference standards, analytical blanks, field duplicates, preparation duplicates and analytical duplicates. QA/QC results are reviewed in real time, and all data is verified as meeting acceptable thresholds for accuracy, precision, and contamination before inclusion in this release.Drill core and rock samples are sent to ALS Minerals for analysis with sample preparation in Chihuahua, Mexico and analysis in North Vancouver, British Columbia. Samples remain under Company custody until delivery to ALS; sealed bags are transported by Company personnel to ALS Chihuahua. The ALS Chihuahua and North Vancouver facilities are ISO/IEC 17025 certified. Samples are dried, weighed, and crushed to at least 70% passing 2mm, and a 250 g split is pulverized to at least 85% passing 75 µm (PREP-31). Silver and base metals are analyzed using a four-acid digestion and ICP-AES. Over-limit analyses for silver (>100 ppm), lead (>10,000 ppm), and zinc (>10,000 ppm) are re-assayed using an ore-grade four-acid digestion and ICP-AES (ME-OG62). Samples with over-limit silver assays > 1500 ppm are analyzed by 30-gram fire assay with a gravimetric finish (Ag-GRA21). Gold is assayed by 30-gram fire assay and AAS (Au-AA23).Technical DisclosureThe scientific and technical information contained in this news release has been reviewed and approved by Nico Harvey, P.Eng., Vice President Project Development of Silverco, a Qualified Person as defined in National Instrument 43-101.
