Silver X Delivers Production Growth During the Fourth Quarter of 2025

Vancouver, British Columbia, January 08, 2026 SILVER X MINING CORP. (TSX- V: AGX) (OTCQB: AGXPF) (F: AGX) (“Silver X” or the “Company“), is pleased to announce its operating results for the fourth quarter ending December 31, 2025 (“4Q25”) at the Company’s Nueva Recuperada property (the “Project”) in Peru.

4Q 2025 Production Highlights

  • Processed tonnage increased to 41,635 tonnes in 4Q25, up from 33,505 tonnes in 3Q25, representing a 24% quarter-over-quarter increase.
  • Silver equivalent ounces (“AgEq”) processed rose to 266,995 oz in 4Q25, compared to 227,315 oz in 3Q25–a 17% sequential improvement–driven primarily by higher throughput while maintaining consistent head grades.
  • The increase in silver equivalent ounces was achieved despite higher average silver prices in 4Q25, which averaged approximately US$55/oz compared to US$40/oz in 3Q25, demonstrating operational stability and grade consistency.
  • Gold production increased to 667 ounces in 4Q25, up from 398 ounces in 3Q25, representing a 67% quarter-over-quarter increase.

“This quarter marks an important step forward in Silver X’s operational ramp-up” said José M. Garcia, CEO of Silver X. “We delivered strong sequential growth in throughput and production while maintaining grade consistency, validating the investments we’ve made in development and operational coordination. The increase in gold production further strengthens our revenue mix and cash flow profile. As we continue to open new mining fronts and advance our 40,000-meter drilling program, we are positioning Nueva Recuperada for sustained production growth and meaningful district-scale value creation.”

The strong performance in 4Q25 reflects Silver X’s ongoing focus on increasing mining and processing capacity, improving mine access and development, and executing on its operational growth strategy at Nueva Recuperada. Continued investment in underground development, combined with improved operational coordination, has positioned the Company for further production growth in upcoming quarters.

The Company’s previously announced 40,000-meter drilling program, together with sustained development of new mining fronts, is expected to support both near-term production growth and longer-term resource expansion across the district.

(2) AgEq ounces produced were calculated based on all metals produced using the average sales prices of each metal for each month during the period. Revenues from concentrate sales does not consider metallurgical recoveries in the calculations as the metal recoveries are built into the sales amounts.

Cautionary Note regarding Production without Mineral Reserves

The decision to commence production at the Nueva Recuperada Project and the Company’s ongoing mining operations as referenced herein (the “Production Decision and Operations“) are based on economic models prepared by the Company in conjunction with management’s knowledge of the property and the existing estimate of mineral resources on the property. The Production Decision and Operations are not based on a preliminary economic assessment, a pre-feasibility study or a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with the Production Decision and Operations, in particular: the risk that mineral grades will be lower than expected; the risk that additional construction or ongoing mining operations are more difficult or more expensive than expected; and production and economic variables may vary considerably, due to the absence of a detailed economic and technical analysis in accordance with NI 43-101.
