Signature Resources Extends Depth Continuity by 200 metres at Lingman Lake with Notable Intercepts in LM 25-05

Signature Resources Ltd. (SGU) announced drill results from hole LM 25-05 at its 100% owned Lingman Lake project in Ontario. The hole successfully extended the North Zone to a 600m vertical depth and the South Zone to a 400m vertical depth, validating the company's geological model.

Notable intercepts include: - 1.37 g/t Au over 32m in South Zone B - 1.62 g/t Au over 7m in North Zone B

Management identified Target Area A, a 400m untested interval between holes LM 25-03 and LM 25-05, as a high-priority zone for future drilling to expand the mineral inventory. Assay results for three holes targeting the western extension of the West Zone (LM 25-06, 07, 08) remain pending.

The company restructured its land tenure, reducing claims from 1,274 single-cell to 159 multi-cell claims, retaining ~85% of the 32 km wide Lingman Lake Greenstone Belt. This release follows a series of drill updates throughout 2025 and early 2026 that progressively extended mineralization deeper and validated the structural model.

Signature Resources Ltd. (SGU) released a routine positive exploration update that aligns with its stated Winter 2025-26 drilling program, which targets approximately 3,900 meters. The results confirm depth continuity and support the company’s geological model, though they do not materially alter the maiden resource estimate released in May 2025.

The intercepts are consistent with prior step-outs, such as LM 25-03, which extended the North Zone by 249 meters in April 2026. No new catalysts or unexpected discoveries were presented, suggesting the market had already priced in the depth potential from earlier holes in the program. Financially, the impact is neutral in the near term as the company remains in the exploration phase with no revenue generation.

Signature Resources Ltd. (SGU) is a junior gold explorer focused on the Lingman Lake Gold Project, located in the Red Lake District of Ontario, a Tier-1 mining jurisdiction. The company’s flagship property, Lingman Lake, is 100% owned and covers approximately 24,821 hectares.

In May 2025, the company announced a maiden resource estimate consisting of 2.15 million tonnes of Indicated resources grading 1.38 g/t Au for approximately 95,200 ounces, and 18.4 million tonnes of Inferred resources grading 1.14 g/t Au for approximately 674,320 ounces, totaling roughly 770,000 ounces. The site has historical significance, having produced 60,865 ounces between 1945 and 1949. Historic underground infrastructure at the location includes a 131-meter shaft and three levels.

The company is led by CEO J. Dan Denbow (CFA), with a board comprising mining and financial experts. Head Geologist Walter Hanych brings more than 40 years of experience to the team.
