SILVER X MINING CORP . ANNOUNCES SIGNIFICANT INCREASE IN MINERAL

RESOURCE ESTIMATE FOR THE NUEVA RECUPERADA PROJECT, INCLUDING

ADDITIONAL HIGH-GRADE RESOURCE AT THE PLATA MINING UNIT

Vancouver, British Columbia, February 26, 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 an updated mineral resource estimate for its Nueva Recuperada Property in Huancavelica,

Peru. This Technical Report is under National Instrument 43 -101 Standards of Disclosure for Mineral

Projects (“NI 43-101”) and includes a significant increase in resources for the Plata Mining Unit (formerly

known as Esperanza), reflecting the Company’s ongoing exploration success and commitment to

expanding its resource base.

The Technical Report prepared by Mr. A. David Heyl is dated February 15, 2025, with an effective date of

October 01, 2024, and will be available on SEDAR+ at www.sedarplus.ca and on the Company’s website

at www.silverxmining.com in less than 45 days.

Key Highlights:

• Overall Nueva Recuperada Property measured and indicated resources grew from 3.60 MT to 4.26

Mt, a +18% increase, and Property inferred resources increased from 11.89 MT to 17.18 M T, a

+45% increase.

• Plata Mining Unit is a high -quality, historical, operating target with indicated recoverable

resources of 0.951 MT at 6.11 opt Ag, 4.24% Zn and 2.44% Pb.

• Total contained indicated silver for the Plata Mining Unit now stands at 5.81 Moz Ag.

• Recoverable inferred resources of 5.394 MT at 4.82 opt Ag, 3.35% Zn, and 1.98% Pb.

• Total contained inferred silver for the Plata Mining Unit now stands at 26.00 Moz Ag.

• The Plata Mining Unit provides substantial growth of resources to the overall Nueva Recuperada

Property.

"Our Nueva Recuperada Property continues to position itself as one of the most relevant silver projects in

South America. We are developing an outstanding asset, a district -scale property that will see mining

activities for several decades” said Silver X CEO, Jose M. Garcia.

“The Plata Mining Unit stands out as a high-grade project where we have managed to identify 6.35 MT of

resources on 19 veins out of the 171 veins that are mapped in the area. As a producing company, we

envision an opportunity to combine fast-track production with a growing resource in a good silver market.

Nueva Recuperada will accomplish fast organic growth over the next few years”.

Plata Mining Unit (PMU) Overview:

The Plata Mining Unit is strategically located just 15 km from the Nueva Recuperada Plant, which provides

critical operational and logistical support, including energy and access to established infrastructure.

PMU benefits from a robust logistical network with roads crossing the concession area, ensuring seamless

connectivity.

A 1,000-hectare easement agreement valid until 2039 further enhances its long-term operational stability.

PMU encompasses 8 royalty-free mining concessions, covering a total area of 4,228.5 hectares.

Figure 1.5 – Plata Mining Unit Concessions and Veins

Over 120 km on 19 mineralized veins at the Plata Mining Unit have been historically mapped and over 170

individual veins recognized within the concessions, demonstrating its extensive resource potential. The

historic data density is remarkable, with over 13,475 channel samples collected from underground

workings and 267 diamond drill holes, and including 2,298 surface rock chip samples and 8,809

underground channel samples.

Exploration and Resource Insights

The Plata Mining Unit’s historic exploration efforts were focused on the Esperanza 2001 Vein, where high-

grade mineralization trends sub -vertically to the west. The vein remains open at depth, with limited

exploration conducted below Level 520 (only three levels were developed). In the last year of the historical

operations (2013) a few of the veins being explored had gold assays run on the samples, with results very

similar to those found at Tangana. Antimony is found in abundance at least two of the nine Plata

subsectors. The Plata Mining Unit has extensive exploration potential to be examined, including porphyry

and dome systems with disseminated and stockwork mineralization.

Future work will prioritize expanding the lateral and depth extents of the resource. The vein has been

mined historically by selective methods, with cut-off grades exceeding 16 oz AgEq per tonne.

Cautionary Note Regarding Production without Mineral Reserves

The decision to commence production at the 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 inferred 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.
