STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) 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:

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. 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.

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.

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. 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 favorable 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.
