Snowline Gold Awards Key Contracts and Commences Prefeasibility Study on its Flagship Rogue Project, Yukon

On December 16, 2025, Snowline Gold announced the commencement of a fully funded Prefeasibility Study (PFS) for its flagship Valley gold deposit at the Rogue Project in the Yukon. The company has appointed reputable engineering firms to lead the study: Wood Canada Limited for lead engineering and integration, SRK Consulting for geoscience and mine engineering, and WSP Canada Inc. for tailings storage facility engineering. Extensive fieldwork to support the PFS, including sonic and geotechnical drilling, was already completed during the 2025 field season. The company anticipates the PFS will take 12 to 15 months to complete.

This news is a material and positive development, representing a critical de-risking milestone for Snowline Gold. The commencement of a PFS is the logical and expected next step following the company's highly successful 2025, which included: - Massive Resource Growth (May 15): A 96% increase in Measured & Indicated resources to 7.94 million ounces of gold at a strong grade of 1.21 g/t. - Robust PEA (June 23): The Preliminary Economic Assessment demonstrated compelling project economics, with a post-tax NPV(5%) of $3.37 billion and an IRR of 25% (at $2,150/oz gold), establishing Valley as a tier-one asset. - Major Financing (Sept 4): A significantly oversubscribed financing raised gross proceeds of $102 million, providing a multi-year runway and fully funding the PFS and ongoing exploration. - TSX Graduation (Nov 28): Uplisting to the senior Toronto Stock Exchange, enhancing liquidity and broadening the potential investor base.

Initiating the PFS formalizes the project's transition from a discovery/exploration story to a development-focused one. This advanced study will refine engineering, mine design, and cost estimates (both CAPEX and OPEX) far beyond the conceptual level of the PEA. Crucially, a successful PFS can be used to declare mineral reserves, the highest confidence category of a mineral asset.

The appointment of well-respected engineering firms like Wood and SRK lends significant credibility to the process. The fact that the company has already completed extensive supporting fieldwork in 2025 demonstrates efficient and forward-thinking management, positioning them to advance the study rapidly. While the market likely anticipated this step, the formal announcement confirms the company is executing its strategy effectively and on schedule.

Snowline Gold Corp. is a Yukon-focused gold exploration company advancing its district-scale portfolio in the Selwyn Basin. Its flagship asset is the 100%-owned Valley gold deposit within the Rogue Project. Valley is a large, near-surface, bulk-tonnage Reduced Intrusion-Related Gold System (RIRGS). The May 2025 Mineral Resource Estimate defined 7.94 million ounces of Measured & Indicated resources at 1.21 g/t Au, and the subsequent June 2025 PEA outlined a potential large-scale, long-life, and highly profitable open-pit mining operation.
