Vancouver, British Columbia--(Newsfile Corp. - October 7, 2025) - Santacruz Silver Mining Ltd. (TSXV: SCZ) (OTCQX: SCZMF) (FSE: 1SZ) ("Santacruz" or the "Company") is pleased to announce the initiation of development activities and the pursuit of full production permitting at its wholly-owned Soracaya Project ("Soracaya" or the "Project"), located in the Potosí Department, Bolivia. These activities mark a key step toward advancing the Project to a production decision.
Arturo Préstamo, Executive Chairman and CEO of Santacruz, commented: "With the preliminary mine plan in place and the permitting process underway, Soracaya is emerging as a cornerstone growth project for Santacruz in Bolivia. Its high-grade resource, strategic location, and synergies with existing operations give us confidence in its ability to deliver long-term value for shareholders and stakeholders alike."
Mr. Préstamo continued: "By advancing the Project and preparing for future construction, we are laying the foundation to add another producing mine to our portfolio while we keep a disciplined approach to cost control and operations improvements. Our work at Soracaya represents a clear commitment to Santacruz's long-term growth and expansion in Bolivia."
Soracaya is a high-grade, silver-rich project, featuring mineralization along reactivated faults with replacement and brecciated sulphides, geological characteristics typical of some of the world's most productive silver deposits. Since 1999, more than 29.6 km of drilling across 90+ holes has provided extensive geological data, supporting robust resource modeling and preliminary mine planning.
With this resources base in place, Santacruz is now focused on completing permitting and advancing Soracaya toward full construction, an important step in the Company's strategy to grow its Bolivian production base. Details regarding the full construction decision will be shared at a later stage.

Notes:
1) The current Resource Estimate was prepared by Garth Kirkham, P.Geo., of Kirkham Geosystems Ltd.
2) All mineral resources have been estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum ("CIM") definitions, as required under National Instrument 43-101 ("NI 43-101").
3) The Mineral Resource Estimate was prepared using a 10% zinc equivalent cut-off grade. Cut-off grades were derived from $3.65/lb. copper, $21.00/oz silver, $1.15/lb. zinc and $1.00/lb. lead. This cut-off grade was based on current smelter agreements and total OPEX costs of $156.00/t based on 2023 actual costs derived from the Porco mine data, with process recoveries of 70.0% for copper, 80.0% for zinc, 70.0% for lead, and 85% for silver. All prices are stated in $USD.
4) An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
5) Mineral resources are not mineral reserves until they have demonstrated economic viability. Mineral resource estimates do not account for a resource's mineability, selectivity, mining loss, or dilution. All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to add precisely.
