STLLR Gold Announces Remaining Tower Gold Project Infill Drilling

Results

TORONTO, ONTARIO, April 17, 2024 – STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) (“STLLR” or the

“Company”) announces the final assay results from the infill and confirmatory drilling program at the 55 Zone,

Westaway and Windjammer North Deposits at the Golden Highway Area (western end) of the Tower Gold

Project in Timmins, Ontario, Canada.

Table 1: 55 Zone, Westaway, and Windjammer North Drilling Highlights (See Figures 2 , 3, & 4 for drill hole

location map and section views of the 55 Zone drilling):

Deposit Hole ID Result

Westaway MGH23-438 4.32 g/t Au over 15.60 m (incl. 6.63 g/t Au over 8.00 m)

55 Zone MGH23-500 2.49 g/t Au over 16.00 m (incl. 17.15 g/t Au over 2.00 m)

55 Zone MGH23-381 0.88 g/t Au over 43.00 m (incl. 1.45 g/t Au over 17.00 m)

55 Zone MGH23-464 2.13 g/t Au over 14.50 m (incl. 4.48 g/t Au over 5.80 m)

Windjammer North MGH23-488 0.77 g/t Au over 111.72 m (incl. 1.01 g/t Au over 26.00)

“g/t Au”: grams per tonne gold; “m”: metres

Tower Gold Project Update:

• 135,423 m in 511 drill holes of the 2023 infill drill program have been released.

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR stated: “ 55 Zone infill drilling results

continued to intersect higher-grade, near-surface gold mineralization. The results from the 55 Zone provided

critical information that allow s us to update and refine the Tower MRE block model . The Westaway and

Windjammer North infill drilling results continue to confirm the Tower MRE block model. We now have

collected all the data from our 2023 infill drilling program.”

Infill Drilling at 55 Zone, Westaway, and Windjammer North

The 55 Zone, Westaway and Windjammer North Deposits are located on the Golden Highway Area (western

end) of the Tower Gold Project in Timmins, Ontario (See Figure 1 for the Tower Gold Project - General Location

Map). Mineralization at the 55 Zone is associated with the Timiskaming age clastic sediment hosted stacked

quartz veins located immediately south of the regional Banded Iron Formation “A” (“ BIF A”) unit and the

Destor Porcupine Fault Zone (“ DPFZ”). The 55 Zone Deposit is characterized by higher- grade, open-pit

mineralization located in the western most portion of the Tower Gold Project . The mineralization at the 55

Zone remains open along strike to the southwest. M ineralization at Westaway is associated with extensional

and stockwork-type quartz veining within Timiskaming age meta- sediments, located between 2 major splays

of the DPFZ. Mineralization at Windjammer North, located immediately south of and parallel to the regional

DPFZ, is hosted primarily within altered komatiitic ultramafic rocks of the Kidd -Munro assemblage in contact

with basaltic flows.

The 2023 drill program at 55 Zone, Westaway and Windjammer North were focused on confirming and infilling

(50 m drill-centre spacings) the Tower Gold Project Mineral Resource Estimate1 (“Tower MRE”). The results at

the 55 Zone provided information that allows the Company to update the Tower MRE block model. Drill hole

MGH23-500 (See Figures 2, 3, and 4) returned higher- grade mineralization at depth of the deposit, while drill

holes MGH23-464 and MGH23-466 (See Figures 2 and 3) returned higher-grade mineralization closer to the

surface.

The drilling results at Westaway and Windjammer North appear to confirm the continuity of mineralization as

estimated by the Tower MRE block model. This is evident particularly with holes MGH23-436, MGH23-438 and

MGH3-488. Overall, the 2023 infill drilling program will provide critical information to update the Tower MRE.

The increased drill density has the potential to upgrade the areas drilled to a higher resource category and

further define future geological models.
