STLLR Gold’s Tower Gold Project Infill Drilling Continues to Confirm

Mineralization at the Jonpol Deposit

TORONTO, ONTARIO, March 28, 2024 – STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) (“STLLR” or

the “Company”) announces the remaining assay results from the infill and confirmatory drilling program at

the Jonpol Deposit at the Garrison (Eastern) area of the Tower Gold Project in Timmins, Ontario, Canada.

Table 1: Jonpol Drilling Highlights:

Hole ID Deposit Result

MGA23-156 Jonpol 1.19 g/t Au over 23.00 m (incl. 6.05 g/t Au over 2.00 m) &

2.09 g/t Au over 21.00 m (incl. 7.46 g/t Au over 3.20 m)

MGA23-157 Jonpol 1.34 g/t Au over 31.00 m (incl. 6.09 g/t Au over 2.00 m)

MGA23-193 Jonpol 1.58 g/t Au over 14.00 m (incl. 8.45 g/t Au over 2.00 m)

MGA23-194 Jonpol 3.15 g/t Au over 3.30 m (incl. 4.98 g/t Au over 2.00 m) &

0.74 g/t Au over 28.70 m (incl. 1.88 g/t Au over 6.00 m)

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

Tower Gold Project Update:

• 123,290 m, in 453 drill holes, of the 140,000 m infill drill program completed have been released.

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR stated: “Results from the Jonpol Deposit

drilling improves our confidence in the resource block model . In addition, the higher -grade intercepts from

holes MGA23-156, MGA23-157, MGA23-193, and MGA23-194 compared to the Tower MRE block model estimate

suggests the potential to expand the known mineralization of the deposit.”

“We anticipate receiving the remaining assay results from our Tower Gold Project drilling in the coming weeks

and plan to update the markets accordingly.”

Jonpol Deposit Drilling

The Jonpol Deposit is located on the eastern end (Garrison Area) of the Tower Gold Project in Timmins, Ontario

(See Figure 1 for the Tower Gold Project - General Location Map). Mineralization at Jonpol is associated with

shear zones within mafic to ultramafic rocks, and is modelled as four contiguous mineralized zones along the

Munro Fault, which is a splay from the regional Destor-Porcupine Fault Zone (“DPFZ”). The 2023 drill program

at Jonpol was focused on the near-surface infill (up to 150 m below the surface) and extensions of the Tower

Gold Project Mineral Resource Estimate1 (“Tower MRE”).

The results from this batch of drilling (please also refer to the Company’s December 7, 2023 news release for

the previous batch of drilling at Jonpol) appear to confirm the continuity of the Jonpol mineralization as

estimated by the Tower MRE block model. This is evident particularly with holes MGA23-164, MGA23-197 and

MGA23-199A. In addition:

• Drill holes MGA23-156 and MGA23-157 (See Figures 2, 3, & 4): Intersected grades that are higher than

the Tower MRE block model.

• Drill holes MGA23-193 and MGA23-194 (See Figures 2 & 3): Intersected near-surface mineralization and

elevated grades outside the Tower MRE block model.

• Drill holes MGA23-167 and MGA23-196: Geomechanical drilling that will benefit future pit shell designs.

Overall, the drilling at Jonpol confirmed the resource block model, potentially increasing the estimated grades

locally in some areas. The increased drill density (50 m drill-centre spacings) provides additional confidence in

the Tower MRE block model, with the potential to upgrade the areas drilled to a higher resource category and

further define future geological models.

Assessment of the Tower Gold Project Northeastern Ontario, Canada” dated November 29, 20 22, which is available on STLLR Gold’s profile on SEDAR+ www.sedarplus.ca

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.
