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 Windjammer South Deposit at the Golden Highway Area (western end) of the Tower Gold Project in Timmins, Ontario, Canada. STLLR appoints James Gagne, P.Eng., MBA, as the Vice President, Projects & Technical Services.

Table 1: Windjammer South Drilling Highlights (See Figures 2 and 3 for the drill location map and section views):

Tower Gold Project Update:

• 129,737 m, in 477 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: "Windjammer South Deposit infill drilling results continue to confirm the continuity of mineralization of the Tower MRE block model. Drill hole MGH23-484 appears to have intersected mineralization that was previously modelled as waste, suggesting a potential addition to the known mineralization in that area. Overall, the drilling information gives us additional confidence in the Tower MRE block model in the areas drilled."

"We are pleased to announce the appointment of James Gagne, P.Eng., MBA as Vice President, Projects & Technical Services. James brings significant technical and operational experience from the Timmins and Kirkland Lake mining camps. I've known James for the entirety of his mining career; We worked together at Lake Shore Gold and we were involved with the construction and operation of the Bell Creek and Timmins West Mines. James will play an instrumental role as we advance our cornerstone Tower Gold and Colomac Gold Projects."

Windjammer South Deposit Drilling

The Windjammer South Deposit is 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 Windjammer South is associated with extensional and stockwork-type quartz veining within Timiskaming age meta-sediments, located between 2 major splays of the prolific Destor-Porcupine Fault Zone. The 2023 drill program at Windjammer South was focused on confirming and infilling (50 m drill-centre spacings) the Tower Gold Project Mineral Resource Estimate¹ ("Tower MRE").

The results from this batch of drilling (please also refer to the Company's October 19, 2023 news release for the previous batch of drilling at Windjammer South) appear to confirm the continuity of the Windjammer South mineralization as estimated by the Tower MRE block model. This is evident particularly with holes MGH23-468, MGH23-478 and MGH23-507 (See Figures 2 & 3). In addition:

• Drill hole MGH23-484 (See Figures 2 & 3): Intersected significant mineralization in an area previously modelled as waste.
• Drill holes MGH23-483, MGH23-489, MGH23-490, MGH23-493, and MGH23-494: Geomechanical and Geometallurgical drilling that will benefit future mine designs.

Overall, the drilling at Windjammer South confirmed the Tower MRE block model. The increased drill density provides the potential to upgrade the areas drilled to a higher resource category and further define future geological models.

Appointment of VP Projects & Technical Services

The Company has appointed Mr. Gagne to the role of Vice President, Projects & Technical Services. James brings 15 years of progressive experience in mine operations, engineering, and consulting. Previously, Mr. Gagne was with Kirkland Lake Gold as the Mine Superintendent of the Macassa Mine and was then promoted to the role of Manager of Mining. As the Manager, James was responsible for the totality of site operations comprised of 3 shafts, a paste plant, and a processing facility. He was also involved with the execution of various major projects such as the new #4 Shaft, the commencement of the Near Surface Portal deposit, and the new overall mine ventilation upgrade within the complex. At Lake Share Gold (subsequently acquired by Tahoe Resources then Pan American Silver), James was involved with the construction, ramp-up and operation of the Bell Creek and Timmins West Mines in the Timmins Mining Camp. He held various roles in engineering and operations, ultimately becoming the Senior Production Engineer. Prior to joining STLLR, James was the General Manager at Black Rock Engineering within the IONIC Technology Group, a firm that specialized in providing engineering services to mining and heavy industries across North America. Mr. Gagne received his Bachelor of Engineering at Laurentian University, his MBA at the Lazaridis School of Business & Economics at Wilfrid Laurier University and is a Professional Engineer in Ontario.

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.
