STLLR Gold Inc.: Solid Gold Intersections Support STLLR's Strategy at the Hollinger Tailings Project

Toronto, Ontario--(Newsfile Corp. - 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.

Table 1: Hollinger Characterization Program Assay Highlights (For more information see Tables 2 & 3 and Figures 1 to 4):

Zone	Hole ID	Assay Result
Hollinger	HTF25-013	0.66 grams per tonne gold ("g/t Au") over 23.40 metres ("m") (including 0.72 g/t Au over 20.03 m)
Hollinger	HTF25-004	0.52 g/t Au over 25.91 m (including 0.61 g/t Au over 19.05 m)
Hollinger	HTF25-017	0.50 g/t Au over 24.40 m (including 0.55 g/t Au over 7.60 m)
Hollinger	HTF25-020	0.53 g/t Au over 24.40 m (including 0.61 g/t Au over 18.50 m)
Hollinger	HTF25-022	0.59 g/t Au over 20.20 m
Hollinger	HTF25-024	0.55 g/t Au over 25.45 m (including 0.60 g/t Au over 21.90 m)
Hollinger	HTF25-033	0.50 g/t Au over 24.40 m (including 0.53 g/t Au over 9.15 m)
Hollinger	HTF25-040	0.54 g/t Au over 23.05 m (including 0.65 g/t Au over 6.50 m & 0.57 g/t Au over 9.15 m)
Hollinger	HTF25-127	0.55 g/t Au over 21.35 m (including 0.86 g/t Au over 3.80 m & 0.60 g/t Au over 8.35 m)

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.

Quality Control Procedures
Tailings core is collected by four-inch diameter continuous sonic coring. Tailings samples are cut, with half sent to ALS Laboratories Inc. (ALS) for drying to a maximum temperature of 60-degree Celsius. The samples are then sieved through a -180 µm screen (Tyler 80 mesh) to a 1.00 kg split of homogenize minus fraction material. A 50 g charge is Fire Assayed and analyzed using an AAS finish for Gold. Samples above 10.00 g/t Au are analyzed by Fire Assay with a gravimetric finish. ALS is an ISO 17025 accredited laboratory. STLLR inserts independent certified reference material and blanks with the samples and assays routine pulp repeats, as well as completing routine third-party check assays at Bureau Veritas Commodities Canada Ltd.
