STLLR Gold Intersects 1.23 g/t Au over 59.00 m at the Colomac Main

Deposit and New Zones of Mineralization at Windjammer North

TORONTO, ONTARIO, June 26, 2024 – STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) (“ STLLR” or

the “ Company”) announces a ssay results from the exploration drilling at the Colomac Gold Project in the

Northwest Territories and at the Tower Gold Project in the Timmins Mining Camp in Ontario.

Table 1: 2024 Exploration Drilling Highlights – Colomac Main Deposit & Windjammer North (See Figures 1-8):

Zone Hole ID Assay Result

Colomac Main C24-05 1.23 g/t Au over 59.00 m (incl. 3.23 g/t Au over 6.90 m)

Windjammer North MGH24-528 0.93 g/t Au over 51.00 m (incl. 1.86 g/t Au over 9.00 m)

Windjammer North MGH24-524 1.09 g/t Au over 17.35 m (incl. 2.64 g/t Au over 6.30 m)

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

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR stated: “We continue to intersect very

encouraging gold mineralization outside of the known mineral resources of the Colomac Gold Project and the

Tower Gold Project. We believe both Projects have the potential for continued growth in mineral resources,

as the deposits remain open in several directions. More assay results are expected at both the Colomac Gold

Project and the Tower Gold Project in the coming weeks.”

Colomac Gold Project Drilling – Colomac Main Deposit (See Figures 1-4)

The Colomac Main Deposit, the primary deposit of the Colomac Gold Project, occurs in a north -south striking

differentiated mafic sill , approximately 9 km long and up to 155 m wide, bounded by mafic volcanic rocks.

Mineralization is predominantly free gold spatially associated with quartz- carbonate veining and minor

sulphides.

Drilling in 2024 is focused on the southern -end (Zones 2.5, 3.0, & 3.5) of the Colomac Main Deposit, targeting

areas where there is a lack of drilling information and the potential to intersect higher-grade, open-pit gold

mineralization. Hole C24-05 intersected new mineralization seventy-five metres to the north of Hole C24-011 in

Zone 2.5. This hole tested a zone adjacent to the main deep-rooted structure believed to be the focal point for

fluid flow or one of the potential “feeders” of the Colomac Main Deposit mineralization.

Tower Gold Project Drilling – Golden Highway Exploration Targets (See Figures 5-8)

STLLR has identified several high-potential exploration targets in the Golden Highway area of the Tower Gold

Project (See Figure 5 for the Drill Location Map). These targets are located outside the known mineralization

and drilling will test either potential extensions of the known mineralization or areas where geological

interpretation appears favourable for new gold discoveries.

Windjammer North

Windjammer North is located within the North Corridor volcanics of the northern branch of the Destor

Porcupine Fault Zone. Gold mineralization is associated with pyrite- rich white to light grey quartz -carbonate

veining hosted by massive-to-brecciated ultramafic metavolcanics that have been altered to a green fuchsite-

carbonate assemblage. Hole MGH24-524 intersected mineralization in the ultramafic units, where there was

a gap in data. Hole MGH24 -528 was a significant step- out (0.5 km) to the east of the Windjammer North

Deposit, intersecting mineralization in the same lithological and structural trend as the deposit.
