STLLR Gold Intersects 3.11 g/t Au over 15.70 m at the Jonpol Deposit of the Tower Gold Project and Announces Board Change

STLLR Gold Inc. (STLR) has released additional assay results from its 2026 drill program at the Jonpol Deposit, part of the Tower Gold Project in Ontario. The company’s headline intercept came from hole MGA26-276, which returned 3.11 g/t Au over 15.70 m (9.57 m true thickness). This interval included 5.15 g/t Au over 1.00 m and an uncut bonanza of 49.20 g/t Au over 0.72 m.

Other notable results from the program include hole MGA26-277, which returned 1.44 g/t Au over 33.77 m (12.00 m true thickness); MGA26-275, which returned 2.41 g/t Au over 16.00 m (10.49 m true thickness); MGA26-274, which returned 3.66 g/t Au over 9.00 m (6.35 m true thickness); and MGA26-272, which returned 2.49 g/t Au over 7.05 m (4.22 m true thickness).

The 2026 drilling program is designed to target the strike extension of open-pit mineralization from 400 m to approximately 1,200 m, as well as infill de-risking. To date, a total of 8,536 m has been drilled in the first half of the year. STLLR Gold also announced a change to its board of directors, noting that the change has no material impact on operations.

STLLR Gold Inc. (STLR) is an advanced explorer with a market capitalization of approximately C$195 million and C$28.7 million in cash. The company generates no revenue and carries a going-concern warning. Its primary value driver is the Tower project, which hosts a large gold resource comprising 4 million ounces in the Indicated category and 7 million ounces in the Inferred category, alongside a Preliminary Economic Assessment (PEA). The Jonpol deposit is located within the Tower project.

The company’s 2026 drilling program has already produced a world-class intercept reported on June 18. Recent results confirm that mineralization extends to the west, though at significantly lower grade-thickness than the best hole. These grades remain above the resource average, but the findings dampen the narrative that Jonpol could host multiple bonanza-grade shoots over 1,200 meters.

The stock rallied from approximately C$1.50 to C$2.12 in February and March following initial high-grade hits, which included 16.52 g/t over 5.85 meters and 6.03 g/t over 22.25 meters. The monster hole reported on June 18 caused a price spike to C$1.50, but the stock failed to hold that level and has since drifted to C$1.29. The market has already priced in the excitement of the discovery hole and is now seeking consistent repeatability. Today’s release, which lacks another blockbuster result, is viewed as routine incremental news.

A recent board change is considered non-material to the investment thesis. The latest news de-risks the strike extension by proving mineralized continuity, but the grade-thickness is only moderately above the resource average and materially behind the prior highlight.

STLLR Gold Inc. is a Canadian gold explorer focused on the Timmins Mining Camp, which includes the Tower Gold Project and Hollinger Tailings, as well as the Colomac Project in the Northwest Territories.

At the Tower project, the company holds 4.0 million ounces in the Indicated category at a grade of 0.89 g/t and 7.0 million ounces in the Inferred category. A 2025 Preliminary Economic Assessment outlines a 19-year open-pit and underground operation producing 273,000 ounces per year. The assessment projects an after-tax NPV5% of US$2.5 billion at a gold price of US$3,200/oz. Jonpol is identified as the near-surface, high-grade deposit within Tower.

The Hollinger project involves tailings re-processing, with 412,000 ounces in the Indicated category at 0.35 g/t. The project is permitted under the new Ontario regime and offers potential for near-term cash flow.

Financially, STLLR Gold Inc. holds C$28.7 million in cash and C$35.8 million in working capital, with no debt. The company reported a Q1'26 net loss of C$3.7 million and includes a going-concern caution. Major shareholders include Eric Sprott with approximately 15% and Agnico Eagle with approximately 11%.
