Solid Gold Intersections Support STLLR’s Strategy at the
Hollinger Tailings Project
TORONTO, ONTARIO, April 14, 2025 – STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D)
(“STLLR” or the “Company”) is pleased to announce promising initial results from its
characterization program at the Hollinger Tailings Project (“Hollinger”) in the Timmins Mining Camp
in Ontario, Canada.
Key Takeaways from First Batch of Hollinger Characterization Results
• Consistent Grades: Results confirmed uniform grade profiles across the drilled areas, with
most holes intersecting mineralization throughout their length.
• Gold Grades Warrant Further Studies: Most holes returned favourable grades that warrant
advancing toward a mineral resource estimate and economic studies.
• First Batch Overview: This batch includes 49 of a planned 400 holes targeting the northwest
area of Hollinger. Assay results for the remaining holes are pending.

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR, commented: “We are thrilled
with the initial results from Hollinger. Drilling in the northwest area of the project revealed consistent
gold grades that warrant advancing toward a mineral resource estimate and economic studies. The
uniform gold mineralization throughout the entire length of most holes suggest amenability for
potential mining and milling, pending further technical studies.”
“This batch represents 49 holes of a planned 400 holes that have been completed at Hollinger. The
sonic drills for the characterization program have been efficient and we will provide further updates
as we receive the assay results in the coming weeks. Stay tuned.”
Hollinger Characterization Program
Located in southeast Timmins, Ontario, the Hollinger Tailings Project holds tailings from the historic
Hollinger Mine, once the world’s largest gold mine. Operating from 1910 to 1968, it produced 19 million
ounces of gold at an average grade of 9.9 grams per tonne.1 The site contains an estimated 50–60
million tonnes of tailings. Recent amendments to Ontario’s Mining Act2 streamline permitting,
enabling reprocessing of legacy tailings while promoting environmental remediation. With low capital
requirements and favorable gold prices, the Company believes that Hollinger offers significant
upside potential.
In February 2025, STLLR launched a characterization program to assess the project’s value, establish
a path towards a mineral resource estimate, and gather information for a reclamation plan. Taking
advantage of the favourable winter conditions, the Company has since completed approximately
10,000 m using sonic drills, with holes spaced by 50 m in a grid pattern. Initial assay results delivered
consistent gold grades across multiple holes, providing compelling early evidence to support
advancing toward a mineral resource estimate and further economic evaluation at today’s strong
gold prices. Please review Figures 1 to 4 and Tables 1 to 3 for further context.
