Silver X Announces Filing of NI 43-101 Technical Report for Previously Announced Mineral Resource Estimate for the Nueva Recuperada Project, Including Plata Mining Unit

Vancouver, British Columbia, April 9, 2025 – Silver X Mining Corp. (TSX-V: AGX) (OTCQB: AGXPF) (F: AGX) (“Silver X” or the “Company“), a rapidly growing Peruvian silver producer-developer, is pleased to announce that it has filed an independent technical report (the “Report”) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). This report substantiates the significant increase in the mineral resource estimate for the Nueva Recuperada Project located in Huancavelica, Peru announced on February 26, 2025.

The Report, with an effective date of October 1, 2024, reflects notable increases in both measured and indicated resources, as well as substantial growth in inferred resources, particularly at the Plata Mining Unit (PMU).

Key Highlights from the NI 43-101 Technical Report:

• Overall Mineral Resource Growth:
  • Measured and Indicated (M+I) resources increased by 18% in ore tonnage, from 3.61 million tonnes (MT) to 4.26 MT, and a 70% growth in silver (Ag) contained within these categories, from 8.22 million ounces (Moz) Ag to 14.00 Moz Ag.
  • Inferred resources grew by +45% in tonnage, from 11.89 MT to 17.18 MT, with more than a 50% increase in contained silver, from 58.30 Moz Ag to 88.00 Moz Ag.
• Plata Mining Unit Update (PMU):
  • Indicated resources increased to 0.95 MT at 6.11 oz/ton Ag, with 5.81 Moz of contained silver.
  • Inferred resources at the Plata Mining Unit grew to 5.39 MT at 4.82 oz/ton Ag, with 26.00 Moz of contained silver.
  • This represents a significant increase in both grade and tonnage for the Plata Mining Unit, demonstrating the importance of PMU within the overall resource base of Nueva Recuperada.
• Zinc and Lead Resource Growth:
  • Zinc (Zn) contained in M+I resources increased by +100%, from 45.9 kT to 94.7 kT.
  • Lead (Pb) in M+I resources grew by 25%, from 64.3 kT to 80.1 kT, reinforcing the multi-metal potential of the Nueva Recuperada Project.

“The updated resource estimate for Nueva Recuperada confirms the strategic significance of the Plata Mining Unit within what is rapidly becoming one of the most relevant silver districts in South America,” said Jose M. Garcia, CEO of Silver X. “With a meaningful increase in high-grade resources and only a fraction of the district explored, the Plata Mining Unit is emerging as a foundational asset for Silver X. PMU together with our Tangana Mining Unit underscore the long-term potential of our District.

The recent acquisition of Minera Kolpa by Endeavor Silver is a clear demonstration of the untapped potential in the region and the terrific investment opportunity Silver X represents. As we continue to fast-track development and scale up production, we remain focused on unlocking long-term value and establishing ourselves as a leading silver producer in South America.”
