Management Commentary
Jim MacKenzie, President and CEO of Viscount, commented:
"The upgrade to the OTCQX Best Market reflects the Company's continued focus on strengthening its capital markets presence and improving accessibility for U.S. investors. We believe this transition supports broader investor awareness and aligns with our objective of advancing our asset portfolio in a disciplined and transparent manner."

Strategic Significance
The OTCQX Market provides increased visibility to U.S. investors and improved trading efficiency. Companies traded on OTCQX must satisfy higher qualification standards than those on OTCQB, including ongoing disclosure requirements.

The Company expects that trading on OTCQX will enhance investor accessibility and support continued engagement with a broader shareholder base.

Continued Focus on Asset Advancement

Viscount continues to advance its portfolio of exploration assets, including the Silver Cliff project in Colorado and the Cherry Creek project in Nevada.

The Silver Cliff project is located in the historic Hardscrabble Silver District and comprises 96 lode claims within a large volcanic caldera system known for its silver, gold, and base-metal mineralization. Within the project, the Kate Deposit represents a NI 43-101 compliant near-surface silver resource that forms the foundation of the Company's understanding of the district. In parallel, the Passiflora Porphyry Target has demonstrated extensive hydrothermal alteration consistent with a large porphyry system. Notably, drill hole PF-23-03A intersected 843.9 metres of continuous gold-copper mineralization, which the Company interprets as being on the periphery of a potentially larger intrusive centre. Mineralization at Passiflora remains open in multiple directions.

In Nevada, the Cherry Creek project consists of 219 unpatented and 9 patented claims within a historic mining district that has produced from more than 20 past-producing mines. The district is characterized by multiple styles of mineralization, including silver-gold vein systems, carbonate replacement deposits, jasperoids, and porphyry-related systems. The project is 100% controlled by Viscount and is considered highly prospective for multi-metal discoveries within a district-scale geological setting.

About Viscount Mining (TSXV: VML) (OTCQX: 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 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 indicates extensive hydrothermal alteration consistent with a large porphyry system. Recent drilling by Viscount (hole PF-23-03A) intersected 843.9 metres of continuous Gold-Copper 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 19 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.
