SNOWLINE GOLD FILES PRELIMINARY ECONOMIC ASSESSMENT REPORT FOR ITS VALLEY GOLD DEPOSIT, ROGUE PROJECT, YUKON

Snowline Gold Corp. has filed on SEDAR+ a technical report supporting the preliminary economic assessment (PEA) for its Valley gold deposit on its 100-per-cent-owned Rogue project in Yukon, Canada.

The PEA is a conceptual study of the potential economic viability of Valley's mineral resources and the first economic assessment of any kind on the broader Rogue project. Results of the PEA were disclosed by the company in a June 23, 2025, news release.

The PEA envisions a conventional open-pit mining and milling operation for Valley with a projected 20-year life of mine producing 6.8 million ounces of payable gold with a front-weighted production profile and attractive economic parameters. It demonstrates a $3.37-billion after-tax net present value at a 5-per-cent discount rate at $2,150 (U.S.) per ounce gold, increasing to $6.8-billion at $3,150 (U.S.) per ounce gold, and 544,000 ounces annual average gold production at all-in sustaining costs (AISC) of $569 (U.S.) per ounce gold for the first five full years of production. Full details of the PEA are available in the technical report, available under the company's profile on SEDAR+ and available on the company's website.

The Rogue project and broader infrastructure work considered by the PEA overlaps with traditional territories of the First Nation of Na-Cho Nyak Dun, the Ross River Dena Council and Kaska Nation.

2025 field program update

The primary objective of Snowline's 2025 field campaign is efficient, rapid advancement of Valley to support a prefeasibility study (PFS) and project permitting. Work currently under way includes geotechnical drilling (greater than 3,000 metres) and sonic drilling, engineering studies, and expanded environmental monitoring. Complementing this are 15,000 metres of exploration drilling at Valley planned to support resource expansion and conversion.

Snowline also remains committed to regional exploration at the company's earlier-stage Yukon projects, with the goal of establishing a gold district in the target-rich environment surrounding Valley. Ten thousand metres of first-pass and follow-up drilling are under way, with seven targets across the Rogue (outside of Valley) and Einarson projects drilled to date. Extensive regional surface exploration and geophysical surveying will complement drilling efforts while advancing the numerous targets within Snowline's exploration pipeline.

To date, approximately 18,500 metres have been drilled this season. Initial drill results from the 2025 drill season are forthcoming.

About Snowline Gold Corp.

Snowline Gold is a Yukon-focused gold exploration and development company with an eight-project portfolio covering roughly 360,000 hectares (3,600 square kilometres). The company is advancing its Valley deposit -- a large, low-strip, near surface, greater-than-one-gram-per-tonne-gold bulk-tonnage gold system located in eastern Yukon -- while continuing regional exploration of surrounding targets on the Rogue project and the broader district in the highly prospective yet underexplored Selwyn basin.

Snowline's project portfolio sits within the prolific Tintina gold province, host to multiple million-ounce-plus gold mines and deposits across central Yukon and Alaska. The company's comprehensive first-mover position and extensive exploration database provide a distinct competitive advantage and a unique opportunity for investors to be part of multiple discoveries, the advancement of a significant gold deposit and the creation of a new gold district.
