Star Metro - Snowline Gold Files Preliminary Economic Assessment Report for Its Valley Gold Deposit, Rogue Project, Yukon

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^[1] envisions a conventional open pit mining and milling operation for Valley with a projected 20-year LOM producing 6.8 million ounces (Moz) of payable gold with a front-weighted production profile and attractive economic parameters. It demonstrates a C$3.37 billion post-tax net present value at a 5% discount rate (NPV5%) at US$2,150/oz Au, increasing to C$6.80 billion at US$3,150/oz Au^[2], and 544 koz annual average Au production at all in sustaining costs ("AISC")^[3] of US$569/oz^[4] Au for the first five (5) full years of production. Full details of the PEA are available in the Technical Report, available under the Company's profile at www.sedarplus.com and available on the Company's website at www.snowlinegold.com.

The Rogue Project and broader infrastructure work considered by the PEA overlaps with Traditional Territories of the First Nation of Na-Cho Nyäk 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 Pre-Feasibility Study ("PFS") and project permitting. Work currently underway includes geotechnical drilling (+3,000 m) and sonic drilling, engineering studies, and expanded environmental monitoring. Complementing this is 15,000 m of exploration drilling at Valley planned to support resource expansion and conversion.

Snowline also remains committed to regional exploration at our earlier-stage Yukon projects, with the goal of establishing a gold district in the target-rich environment surrounding Valley. 10,000 m of first pass and follow up drilling is underway, 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 m have been drilled this season. Initial drill results from the 2025 drill season are forthcoming.

ABOUT SNOWLINE GOLD CORP.

Figure 1. Rogue Project Regional Map

Snowline Gold Corp. is a Yukon Territory-focused gold exploration and development company with an eight-project portfolio covering roughly 360,000 ha (3,600 km ² ). The Company is advancing its Valley deposit - a large, low-strip, near surface, >1 g/t Au bulk tonnage gold system located in the 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 the 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.

USE OF NON-GAAP MEASURES
Certain financial measures referred to in this news release are not measures recognized under IFRS and are referred to as non-GAAP financial measures or ratios. These measures have no standardized meaning under IFRS and may not be comparable to similar measures presented by other companies. The definitions established and calculations performed by Snowline are based on management's reasonable judgement and are consistently applied. These measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.

The non-GAAP financial measures used in this news release and common to the gold mining industry are all-in sustaining cost per ounce of gold sold and free cash flow.

All-in sustaining cost per ounce of gold sold and free cash flow are non-GAAP financial measures or ratios and have no standardized meaning under IFRS Accounting Standards ("IFRS") and may not be comparable to similar measures used by other issuers. As Valley is not in production, the Company does not have historical non-GAAP financial measures nor historical comparable measures under IFRS, and therefore the foregoing prospective non-GAAP financial measures or ratios may not be reconciled to the nearest comparable measures under IFRS.

Forward-looking statements in this news release include, but are not limited to, the Company's expectations and estimates with respect to: the economic and scoping-level parameters of the PEA and Valley; the anticipated timeline for completion of a potential PFS; mineral resource estimates; the cost and timing of any development of Valley; the proposed mine plan and mining methods; dilution and mining recoveries; processing method and rates; production rates; projected metallurgical recovery rates; infrastructure requirements; energy sources; capital, operating and sustaining cost estimates; the projected life of mine and other expected attributes of Valley; the NPV; future metal prices; the timing of any engineering, environmental assessment or Indigenous consultation processes; the expansion of environmental baseline monitoring programs; future drill programs and general business and economic conditions.

Statements relating to "mineral resources" are deemed to be forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the mineral resources described can be profitably produced in the future. Generally, forward-looking statements can be identified using forward-looking terminology. Wherever possible, words such as "may", "will", "should", "could", "expect", "plan", "target", "forecast", "schedule", "prospective", "envision", "continue", "intend", "assume", "anticipate", "believe", "estimate", "budget", "predict", "project" or "potential" or the negative or other variations of these words, or similar words or phrases, have been used to identify these forward-looking statements. These statements reflect management's current beliefs and are based on information currently available to management as at the date hereof.

All statements other than statements of historical fact may be forward-looking statements. Forward-looking statements involve significant risk, uncertainties and assumptions. Many factors could cause actual results, performance or achievements to differ materially from the results discussed or implied in the forward-looking statements. Such factors include, among other things: risks related to the inherent uncertainties regarding cost estimates; the use of non-GAAP measures in financial performance accounting; changes in commodity and metal prices; currency fluctuation; financing; unanticipated resource grades and recoveries; infrastructure; results of future exploration activities; cost overruns; availability of materials and equipment; timeliness of government approvals; political risk and related economic risk; unanticipated environmental impact on operations; and risks associated with executing the Company's plans and intentions. These factors should be considered carefully, and readers should not place undue reliance on the forward-looking statements. Although the forward-looking statements contained in this news release are based upon what management believes to be reasonable assumptions, the Company cannot assure readers that actual results will be consistent with these forward-looking statements. Additionally, while the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. These forward-looking statements are made as of the date of this news release, and the Company assumes no obligation to update or revise them to reflect new events or circumstances, except as required by law.
