STLLR Gold Announces Exploration Drilling Results at the Tower Gold Project

Press Release

TORONTO, Ontario, May 21, 2024 – STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) (“STLLR” or the “Company”) announces the assay results from the exploration drilling of prospective targets near the 55 Zone and Westaway Deposits at the Golden Highway Area (western end) of the Tower Gold Project in Timmins, Ontario, Canada. Exploration drilling at the Colomac Gold Project in the Northwest Territories, Canada, has also commenced.Table 1: 2024 Exploration Drilling Highlights – 55 Zone West and Westaway South Limb Targets

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR stated: “Our properties in the Timmins Mining Camp have immense exploration upside. This year, we plan to test some high-potential targets near the Tower Gold Project. The assay results received from recent drilling are very encouraging and warrant follow-up. We intersected gold mineralization west of the 55 Zone Deposit and south of the Westaway Deposit, outside of the known mineral resources. We also drilled targets near the Windjammer and Discovery Deposits and we are awaiting assay results.”

“We have also commenced exploration drilling at our Colomac Gold Project in the Northwest Territories. This year, we are targeting zones with the potential for higher-grade, open-pit mineralization near the south end of the Colomac Main Deposit. We anticipate receiving assay results in a few weeks from now.”

Golden Highway Exploration Targets

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

55 Zone West Extension (See Figures 1, 2 and 3)

Holes MGH24-517 and MGH24-520 drill-tested an area across a major fault to the west of the 55 Zone Deposit. This area has the potential to extend the Golden Highway mineralization along strike. Promising results demonstrate intersections of gold mineralization, and future follow-up drilling is warranted. STLLR’s land includes an additional 3 km of geological strike which has limited exploration work to-date.

Westaway South Limb (“Westaway SL”) (See Figures 1, 2, and 4)

The Westaway Deposit is primarily associated with the Timiskaming-age clastic, sediment-hosted stacked quartz veins located immediately south of the regional banded iron formation on the north limb of a folded basin. Drilling in the area south of the Westaway Deposit tests the potential for similar mineralization controls along the south limb of the basin. Initial results confirm continued gold mineralization along the primary mineralizing structures as well as a wider mineralized zone at Westway. Based on positive indications that the mineralized system continues within the southern portion of the basin, follow-up work is required in the winter.

Windjammer and Discovery

The Company is currently drilling targets near the Windjammer and Discovery Deposits, with assay results pending.

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.
