STLLR Gold Intersects 16.52 g/t Au over 5.85 Metres at the Jonpol Deposit of the Tower Gold Project

STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) has released the first set of assay results from its 2026 drilling program at the Jonpol Deposit (Jonpol) on the Garrison Property of the Tower Gold Project (Tower) in the Timmins Mining Camp of Ontario, Canada.

First assays from 2026 Jonpol drilling

The initial results include high-grade, near-surface intersections in targeted areas along the western strike extension of Jonpol.

Key highlights (Table 1)

• MGA26-248 (Jonpol): 16.52 g/t Au (uncut) / 9.22 g/t Au (cut) over 5.85 metres (3.30 m true thickness).
• MGA26-251 (Jonpol): 1.46 g/t Au over 22.65 m (14.31 m true thickness), including 5.27 g/t Au over 3.15 m (1.98 m true thickness).

Program objectives and development

STLLR said the 2026 drill program is planned at an estimated 8,000 metres in the first half of the year, with plans for the second half currently being finalized. The program is designed around two primary objectives:

• Strike extension: Most of the targeted drilling is focused on the western extension of Jonpol’s open-pit mineralization. Successful results could expand the strike length from 400 m (as defined in the Tower Preliminary Economic Assessment) to approximately 1,200 m. Jonpol remains open along strike and at depth.
• Infill and de-risking: Drilling is also intended to confirm the block model and support potential expansion of higher-grade mineralization for inclusion in the Tower Mineral Resource Estimate.

Geological setting

Jonpol is located on the Garrison Property at the eastern end of Tower along the Munro Fault, a splay from the regional Destor-Porcupine Fault Zone (DPFZ). Mineralization is hosted in structurally controlled alteration zones within mafic to ultramafic rocks, with gold mineralization closely associated with felsic intrusive rocks.

Assay intercepts and drill details

Intersections were calculated using a 0.30 g/t Au cut-off, with a maximum of 5 m internal dilution and a 25 g/t Au cap. True thickness (TT) was calculated in Leapfrog Geo, perpendicular to the interpreted plane of mineralization using the dip and dip azimuth of the mineralized zones.

Selected drilling intercepts (Table 2)

• MGA26-248: 160.15–166.00 m (5.85 m), TT 3.30 m; 9.22 g/t Au (cut) and 16.52 g/t Au (uncut).
• MGA26-251: 49.70–72.35 m (22.65 m), TT 14.31 m; 1.46 g/t Au, including 49.70–52.85 m (3.15 m), TT 1.98 m; 5.27 g/t Au.

Drill hole details (Table 3)

• MGA26-248: Depth 166.00 m; azimuth 158.10; inclination -51.53.
• MGA26-249: Depth 288.00 m; azimuth 159.02; inclination -56.11.
• MGA26-250: Depth 177.00 m; azimuth 159.98; inclination -45.05.
• MGA26-251: Depth 175.00 m; azimuth 160.02; inclination -45.00.

Quality control procedures

STLLR reported that NQ drill core is oriented and cut with half sent to ALS Laboratories Inc. for drying and crushing to -2 mm, with a 1.00 kg split pulverized to -75 µm (200#). ALS is ISO 17025 accredited. A 50 g charge is fire assayed and analyzed using an AAS finish for gold. Samples above 10.00 g/t Au are fire assayed with a gravimetric finish, and selected samples with visible gold or high-grade mineralization are analyzed using metallic screen fire assay on a 1.00 kg sample. The company said it uses inserts of independent certified reference material and blanks, routine pulp repeats, and third-party check assays.

Impact and company perspective

STLLR said the first batch of assays intersected high-grade mineralization in targeted areas along the western strike extension and that the results yielded grades exceeding the current average open-pit grades at Jonpol in the Tower Mineral Resource Estimate. The company also stated the results reinforce continuity of known mineralization and support its geological model, with the potential to expand higher-grade mineralization.
