Viscount Mining Corp. Provides Market Activity Clarification and Operational Update

Vancouver, December 22, 2025 - Viscount Mining Corp. (TSXV: VML) (OTCQB: VLMGF) provides market activity clarification and operational update.

Viscount wishes to clarify recent market activity and reaffirm the Company's operational outlook. During the final 30 minutes of trading on Friday, December 19, the Company observed irregular trading activity in its shares. Viscount confirms that there have been no material changes to its business, assets, or planned operations.

In keeping with best practices for market transparency, the Company's Chief Executive Officer promptly contacted the Canadian Investment Regulatory Organization (CIRO) and formally requested a comprehensive review of the trading activity.

As previously disclosed in two news releases issued during the week of December 8, Viscount continues to advance its exploration strategy at the Silver Cliff Project, with drill programs planned at both the Kate and Passiflora targets.

Kate - Near-Term Resource Growth

The planned drill program at the Kate target is designed to expand and upgrade the existing silver resource through:

• Step-out drilling at Kate North and Kate Northeast to test extensions of known mineralization

• Drill testing of the Ben West structural corridor, a key control on mineralization

• Infill drilling within the current resource envelope to support future technical studies and an updated NI 43-101 resource estimate

Passiflora - District-Scale Copper-Gold Potential

At the Passiflora target, exploration work continues to highlight a compelling copper-gold system with characteristics consistent with a deeper porphyry source, including:

• A well-defined copper-gold pathfinder geochemical corridor coincident with Quantec MT conductivity highs, mapped alteration, and mineralized intervals intersected in deep drill hole PF-23-03A

• A planned first drill hole of 2026 designed to test breccia pipes and extend into the core of the Quantec MT anomaly. This angled hole is expected to reach approximately 1,500 metres and is intended to test the heart of the system

Viscount remains focused on disciplined exploration, systematic resource growth, and the delivery of long-term shareholder value, while maintaining the highest standards of market disclosure and regulatory compliance.

About Viscount Mining (TSXV: VML) (OTCQB: VLMGF)

Viscount Mining Corp. is a project generator and mineral exploration company focused on advancing high-quality silver, gold, and copper assets in the Western United States. The Company's portfolio includes the Silver Cliff silver project in Colorado and the Cherry Creek multi-metal district in Nevada.

Silver Cliff Project - Colorado

Silver Cliff is located in the historic Hardscrabble Silver District and comprises 96 lode claims with year-round paved access and established local infrastructure. The project covers a large volcanic caldera system recognized for its silver, gold, and base-metal potential.

The property includes two principal zones of focus:

• Kate Deposit (Silver Resource Area): The Kate hosts a NI 43-101 compliant near-surface silver resource published by an independent QP (details: Measured & Indicated and Inferred silver resources were reported in the Company's technical disclosure; investors are encouraged to review the full technical report available on SEDAR+ for tonnage, grade, and methodology).

• Passiflora Porphyry Target: Historical and modern drilling indicate extensive hydrothermal alteration consistent with a large porphyry system. Recent drilling by Viscount (hole PF-23-03A) intersected 843.9 metres of continuous copper-gold mineralization, which the Company interprets as being on the periphery of a potentially larger intrusive centre. Mineralization remains open in multiple directions.

Cherry Creek Project - Nevada

Cherry Creek covers 219 unpatented and 9 patented claims in a well-known historic mining district approximately 50 miles north of Ely. The property includes more than 20 past-producing mines and hosts several styles of mineralization, including silver-gold veins, carbonate-replacement (CRD) zones, jasperoids, and porphyry-related alteration. The district is 100% controlled by Viscount and is considered highly prospective for multi-metal discoveries within the broader mineralized system.

Viscount's strategy is to acquire, explore, and advance high-potential mineral properties through systematic geological work, while continuing to build partnerships that support long-term development.
