CEO.CA Chairman's Briefing

Toronto, Ontario--(Newsfile Corp. - September 5, 2024) - STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) ("STLLR" or the "Company") announces assay results from the exploration drilling at targets in the Golden Highway area of the Tower Gold Project (the "Project") in the Timmins Mining Camp in Ontario, Canada.

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR stated: "We intersected significant mineralization in the western portion of the Last Chance Zone, located at the western end of the Tower Gold Project. These results indicate the potential to expand known mineral resources both westward and at depth, justifying future drilling in the Last Chance Zone."

Tower Gold Project Drilling - Golden Highway Exploration Targets (See Figures 1, 2, & 4)

STLLR has identified several high-potential exploration targets in the Golden Highway area of the Project (See Figure 1 for the Drill Location Map). These targets are located outside of the known mineralization and drilling will test either the potential extensions of the known mineralization or areas where the geological interpretation appears favourable for new gold discoveries.

Last Chance Zone

The Last Chance Zone, part of a 5 km-long northern shear corridor extending west from the Project along the Destor-Porcupine Fault Zone ("DPFZ"), consists of intercalated ultramafic and tholeiitic basalt rocks that are associated with the Windjammer North and Discovery Deposits. Drill holes MGH24-535 and MGH24-536 targeted a magnetic low anomaly based on new interpretations of mineralization controls. The drilling intersected cross-cutting structures hosting gold-bearing quartz veins that may have been missed in previous drilling.

Windjammer Central Infill Drilling

Windjammer Central is a continuation of the Windjammer Deposit located immediately north of the regional Banded Iron Formation, hosted in Timiskaming-age, clastic sediment-hosted stacked quartz veins. The mineralization is bound to the north by the mafic to ultramafic units associated with the Discovery Deposit. Holes MGH23-347 and MGH23-348 were part of the 2023 infill drilling program. These results successfully confirmed wide intervals of near surface mineralization at the Windjammer Central Deposit. These holes will be included in the updated Mineral Resource Estimate for the Project.

Windjammer North

Windjammer North is located within the North Corridor volcanics of the northern branch of the DPFZ. Gold mineralization is associated with pyrite-rich, white-to-light grey quartz-carbonate veins, hosted by massive to brecciated ultramafic metavolcanics altered to a green fuchsite-carbonate assemblage. The latest results intersected mineralization and require further interpretation.

Quality Control Procedures
NQ drill core is oriented and cut with half sent to ALS Laboratories Inc. (ALS) for drying and crushing to -2 mm, with a 1.00 kg split pulverized to -75 µm (200#). ALS is an ISO 17025 accredited laboratory. 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 and selected samples with visible gold or high-grade mineralization are assayed by Metallic Screen Fire Assay on a 1.00 kg sample. STLLR inserts independent certified reference material and blanks with the samples and assays routine pulp repeats and coarse reject sample duplicates, as well as completing routine third-party check assays at Bureau Veritas Commodities Canada Ltd.

Qualified Person
John McBride, MSc., P.Geo., Vice President of Exploration for STLLR, who is the "Qualified Person" as defined by NI 43-101 for this project, has reviewed and approved of the technical disclosure contained in this news release.

About STLLR Gold
STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) is a Canadian gold development company actively advancing two cornerstone gold projects in Canada: The Tower Gold Project in the Timmins Mining Camp in Ontario and the Colomac Gold Project located north of Yellowknife, Northwest Territories. Each of these two projects has the potential for a long-life and large-scale operation and are surrounded by exploration land with favourable upside potential. STLLR's experienced management team, with a track record of successfully advancing projects and operating mines, is working towards rapidly advancing these projects.
