Goliath Resources Reports Significant Drill Results at Surebet Discovery

Goliath Resources Limited has announced significant drill results from the Bonanza Zone at the Surebet Discovery on its 100% owned Golddigger Property in the Golden Triangle, British Columbia. The company has reported two drill holes, GD-26-431 and GD-26-442, which have intersected high-grade gold mineralization.

Drill hole GD-26-431, located in the western fringes of the mineralized system, intersected two neighboring broad mineralized intervals within the Bonanza Zone. The first interval assayed 9.12 grams per tonne (g/t) of gold equivalent (AuEq) over 11.27 meters, including a higher-grade core of 13.89 g/t AuEq over 7.14 meters. This interval is characterized by stockwork and breccia veins associated with calc-silicate and biotite alteration, featuring visible gold to the naked eye (VG-NE) alongside galena, sphalerite, and pyrrhotite. The second interval assayed 4.70 g/t AuEq over 3.03 meters, within a broader interval of 1.08 g/t AuEq over 20.00 meters. This interval is proximal to the Big Bulk Zone and is characterized by stockwork veins and veinlets associated with biotite, sericite alteration, and pyrrhotite.

Drill hole GD-26-442, targeting the northern 100-meter step-out expansion of the Bonanza Zone, intersected 8.35 g/t AuEq over 4.15 meters, including a high-grade interval of 31.42 g/t AuEq over 1.00 meter. This intercept is part of the new 100-meter Bonanza Zone expansion step-out to the north in 2026, where mineralization consists of quartz-sulphide veins associated with localized biotite and sericite alteration, VG-NE, galena, sphalerite, and pyrrhotite.

The expanded high-grade core of the Bonanza Zone is located above the valley floor, potentially making it a great target for initial underground mining operations using gravity methods. Drilling conducted during the 2026 program has expanded the Bonanza Zone by 750 meters to the southwest, 100 meters to the west, 100 meters to the north, and 160 meters to the northeast. The Bonanza Zone remains open for expansion, and assays are pending.

The total footprint of the Surebet system is 2.01 km², representing a 12% increase compared to 1.8 km² defined prior to the 2026 drilling season. Multiple drill holes from 2026 have expanded the Bonanza Zone to 1.51 km² from 1.27 km² (a 19% increase) and the Golden Gate Zone to 1.17 km² from 0.85 km² (a 38% increase), and both remain open for expansion.

Visible Gold to the Naked Eye (VG-NE) has been intersected in multiple veins and shear zones from 52 out of 92 holes drilled in 2026, continuing to confirm the consistency of gold mineralization widely disseminated throughout the Surebet system that remains open laterally and at depth.
