Star Metro - Silver X Acquires the High-Grade Pampas Gold-Silver Project, Expanding its Precious Metal Asset Base in Peru

VANCOUVER, BC / ACCESS Newswire / March 24, 2026 / Silver X Mining Corp. (TSXV:AGX)(OTCQB:AGXPF)(F:AGX) ("Silver X" or the "Company") is pleased to announce that it has entered into a definitive agreement to acquire a 100% interest in the Pampas Gold-Silver Project located in the Department of Huancavelica, Peru.

The Pampas acquisition secures control of an approximately 7,712.5-hectare epithermal project hosting multiple low-sulfidation gold-silver veins and historical and validation results, including rock chip and channel sample values of up to 85.9 g/t Au and 1,065 g/t Ag (Hunter Resources plc, 4 February 2015). The Project represents a potentially important precious metals exploration asset within the Central Andes polymetallic belt.

Strategically, the Pampas Project strengthens Silver X's asset base in central Peru and complements the Company's producing Nueva Recuperada Property. The acquisition adds a new district-scale exploration asset with significant discovery potential within one of the most prospective polymetallic belts of the Central Andes.

With the addition of Pampas, Silver X continues to advance its strategy of building a multi-asset precious metals company, supported by producing operations, high-grade exploration assets and long-term regional processing capacity.

CEO Statement - 2026 Vision Alignment

José M. Garcia, CEO of Silver X, commented: "Pampas is exactly the type of asset we want to add to the Silver X portfolio - high grade, district scale and located in the same mining belt where we are already operating.

What makes Pampas particularly notable is the combination of strong historical grades and a system that has never been systematically drilled. With values reaching 85 grams per tonne gold and over 1,000 grams per tonne silver, Pampas clearly demonstrates the strength of the mineralizing system and the potential to host higher-grade zones.

Strategically, this acquisition strengthens our asset base in Peru and complements our producing Nueva Recuperada operation. Pampas adds a new district-scale exploration opportunity with significant discovery potential within the same prospective mining belt.

Our goal is simple: build Silver X into a high-grade, multi-asset precious metals company. With production already underway at Nueva Recuperada and new district-scale exploration opportunities emerging at Pampas, we believe we are building a platform capable of generating long-term growth and discovery."

Investment Highlights - High-Grade Gold Growth Platform:

• District-scale acquisition: 7,712.5 hectares covering the Pampas and Próspero concessions along a continuous mineralized structural corridor in central Peru.

• High-grade precious metals system: Historical and validation sampling indicates gold-silver mineralization across multiple veins and mineralized zones.

• Large mineralized footprint: Historical work and later public disclosures describe at least 36 mineralized veins with mapped strike lengths of between 100 and 2,000 metres and widths ranging from 0.2 metres to more than 3.0 metres (Hunter Resources plc, 27 August 2014; Hunter Resources plc, 22 December 2014).

• No documented drilling: Despite extensive surface and underground work, the Project has not been systematically drill tested.

• Historical database in place: Historical work by BISA/Buenaventura in 1998-1999 included detailed surface and underground mapping and more than 1,000 multi-element geochemical samples, forming the basis of the historical database referenced in this release (BISA, 1999; Arroyo & Diaz, 2020).

• Independent validation supports upside: Follow-up work by Hunter Resources in 2014 and 2015 confirmed gold-bearing structures and identified additional mineralized extensions under shallow cover (Hunter Resources plc, 27 August 2014; Hunter Resources plc, 4 February 2015).

• District expansion potential: The adjoining Próspero concessions add scale and introduce a copper-enriched polymetallic dimension along the same structural trend.

• Clear path to value creation: Silver X plans to advance Pampas through phased exploration aimed at drill targeting and future mineral resource definition.

Table 1. Historical vein intervals include (see also Figure 2)

Validation work completed by Hunter Resources between 2014 and 2015 confirmed the presence of gold mineralization at Luz and nearby structures, including values of up to 5.91 g/t Au and up to 6.39 g/t Au in areas interpreted as shallow-cover extensions (Hunter Resources plc, 22 December 2014; Hunter Resources plc, 4 February 2015). Subsequent Hunter sampling also reported rock chip and channel sample values of up to 85.9 g/t Au and 1,065 g/t Ag in previously untested extensions (Hunter Resources plc, 4 February 2015).

The Próspero area introduces a copper-enriched polymetallic dimension to the Pampas district, with later reconnaissance work reporting values of up to 4.12 g/t Au, 433 g/t Ag and 5.8% Cu, suggesting potential metal zoning within a vertically evolving epithermal system.

Reported Buenaventura sampling comprised both channel samples and rock chip samples from underground and surface exposures.

Transaction Summary

Under the terms of the agreement, Silver X will acquire 100% of the Project for:

• US$1.7 million in staged cash payments over 24 months.

• A 3.0% NSR royalty with the option to repurchase 1.5% for US$1.5 million during the first four years following the commencement of production.

Geological Setting - Dome Centered High-Grade Epithermal System

The Pampas-Próspero district is centered on an intrusive complex interpreted as part of a Miocene volcanic dome system located within the polymetallic belt of the Central Andes. Historical mapping and later technical synthesis indicate that mineralization across both Pampas and Próspero is structurally controlled and hosted within two principal fault systems (Butler, 2014; Arroyo & Diaz, 2020).

A dominant northwest-trending structure includes the Santo Domingo vein, with approximately 2,000 metres of exposed strike length. A second north-south structural system hosts the Victoria, Gaviota, Melita and Piscococha veins at Pampas, with individual strike lengths of up to 1,250 metres and interpreted extensions toward the Próspero concessions (Butler, 2014; Hunter Resources plc, 27 August 2014).

Pampas Area

At Pampas, mineralization occurs as quartz-sulfide veins and hydrothermal breccias hosted within the intrusive complex and associated structures. Historical and later technical interpretations indicate that higher-grade shoots may be localized where structures change orientation or intersect, generating dilation zones favourable for mineralization (Butler, 2014; Hunter Resources plc, 22 December 2014).

Historical underground workings, including multiple sublevels developed during the 1960s, focused on Santo Domingo, Melita, Victoria and Gaviota, while the broader dome-centre area remains comparatively underexplored at depth (Arroyo & Diaz, 2020).

Próspero Area

The Próspero concessions extend the same structural corridor northwest of Pampas and host at least five mineralized zones identified through historical reconnaissance and later internal technical review. Mineralization described at Próspero includes quartz-sulfide mantos, hydrothermal breccias, copper-enriched zones hosted within dioritic units and strong iron oxide alteration. Reported reconnaissance results include values ranging up to 4.12 g/t Au, 433 g/t Ag, 15.6% Pb, 5.87% Zn and 5.8% Cu (Arroyo & Diaz, 2020).

Validation of Historical Work

Limited underground development was completed during the 1960s on the Santo Domingo, Melita, Victoria and Gaviota veins, including multiple sublevels and approximately 1,347 metres of underground geological mapping (Arroyo & Diaz, 2020).

In 1998 and 1999, Buenaventura Ingenieros S.A. ("BISA") completed detailed underground geological mapping at 1:500 scale, surface geological mapping at 1:2,000 scale, and surface and underground geochemical sampling comprising more than 1,000 samples (BISA, 1999; Arroyo & Diaz, 2020). This work forms the principal historical database referenced in this release.

Despite extensive historical surface and underground work, the Project has not been systematically drill tested, leaving vertical continuity beneath historic workings untested (Hunter Resources plc, 27 August 2014; Hunter Resources plc, 4 February 2015).

Between 2014 and 2015, Hunter Resources digitized, reinterpreted and partially validated the historical dataset through mapping and sampling programs. Public disclosures issued by Hunter on 27 August 2014 and 4 February 2015 summarized the historical Buenaventura data and subsequent Hunter follow-up work, including confirmation of gold mineralization at Luz and adjacent structures, as well as new anomalous zones sampled during the 2014 field program (Hunter Resources plc, 27 August 2014; Hunter Resources plc, 4 February 2015).

Field observations and subsequent interpretation indicate local vein widening, structurally controlled multi-stage mineralization and evidence for mineralization beneath shallow cover, all of which support further evaluation through systematic drilling (Hunter Resources plc, 22 December 2014; Butler, 2014).

Exploration Strategy

Silver X plans to initiate a phased exploration program:

Phase 1

• Validation of historical data

• Detailed structural mapping

• Systematic channel sampling

• Rehabilitation of historic workings

• Induced Polarization (IP) surveys

Phase 2

• 5,000m initial diamond drill program

• Testing high-grade shoots in Victoria, Luz and Santo Domingo

• Drilling structural extensions into Próspero

The objective is to define an initial NI 43-101 compliant mineral resource within 24-36 months.

Epithermal systems of similar age (12-6 Ma) in the Huachocolpa-Julcani-Castrovirreyna belt commonly demonstrate significant vertical development.

Given the absence of systematic drilling at Pampas-Próspero, Silver X intends to prioritize testing, down-dip extensions of known high-grade shoots, structural intersections at depth and potential feeder zones beneath the dome center.

Infrastructure and Regional Mining Context

The Pampas Project is located approximately 40 kilometres in a straight line from Silver X's Nueva Recuperada operation, highlighting its strategic proximity to the Company's existing asset base in central Peru.

Infrastructure advantages include:

• Year-round road access

• Proximity to regional power lines

• Established mining workforce in the region

• Historic underground access points

• Manageable historical environmental footprint

The combination of geological potential and favorable infrastructure positions Pampas-Próspero as a scalable exploration platform.

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.
