Toronto, Ontario – November 13, 2025 – Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) (the “Company” or “Goliath”) announces assays are still pending on 84 holes from this years exploration campaign of which 66 holes contain visible gold to the naked eye (VG-NE) and the majority have multiple occurrences of VG-NE. 100% of the drill holes completed to date on Surebet have intersected substantial quartz-sulphide mineralization and 83 of the 110 drill holes (or 76%) from 2025 contain visible gold observed with the naked eye (VG-NE) clearly demonstrating the discovery potential remaining on the property.

Surebet Discovery Highlights
●
Assays are still pending for 84 holes from this year’s exploration campaign, of which 66 (representing 79% of the total pending) contain visible gold to the naked eye VG-NE with the majority containing multiple occurrences (see table above).
●
83 out of 110 holes (or 76%) drilled in 2025 contain VG-NE and 100% of drill holes have intersected substantial quartz-sulphide mineralization.

●
60 out of 64 holes (or 94%) drilled in 2024 contain VG-NE up to 11.5 mm (7/16 inches) in size, all of which returned high-grade gold.
●
92% of the holes (355 out of 386) drilled to date at Surebet contain VG-NE (see heat map above).
●
The best hole drilled to date is GD-24-260 previously reported from the Bonanza Zone assayed 34.52 g/t AuEq (34.47 Au and 3.96 Ag) over 39.00 meters, including 132.93 g/t AuEq (132.78 Au and 12.98 Ag) over 10.00 meters, and 166.04 g/t AuEq (165.84 Au and 16.07 Ag) over 8.00 meters (see news release dated January 13, 2025). More details on the QA/QC protocol can be found in the section titled “QA/QC Protocol” below.
●
The best hole drilled to date from the RIRG Eocene-aged dykes is GD-22-58 that assayed 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10.00 meters including 19.91 g/t AuEq (19.62 g/t Au and 25.61 g/t Ag) over 6.00 meters, including 23.82 g/t AuEq (23.47 g/t Au and 30.54 g/t Ag) over 5.00 meters, plus a second separate interval down hole of 8.59 g/t AuEq (8.35 g/t Au and 20.74 g/t Ag) over 5.00 meters (see news release dated March 13, 2025). More details on the QA/QC protocol can be found in the section titled “QA/QC Protocol” below.
●
The best hole drilled to date from the calc-silicate altered breccia is drill hole GD-25-337, which intersected 10.60 g/t Au over 22.82 meters, including 15.19 g/t Au over 15.71 meters, including two separate intervals consisting of 37.28 g/t Au or 1.20 oz/t Au over 3.36 meters and 36.11 or 1.16 oz/t Au over 3.08 meters. The intercept is approximately true width, and these assays reflect gold only (AuEq value in the interval will be adjusted accordingly once Ag, Cu, Pb and Zn are received).

Multiple gently dipping gold-mineralized stacked veins have been identified every year on the Surebet high-grade gold discovery. Recent discoveries include RIRG Eocene-aged dykes, Goldilocks Zones where the veins and vertical RIRG dykes crosscut (which are characterized by having high-grade gold in two temperature regimes) and recently discovered high-grade gold in a third distinct rock package, which increases potential tonnage and gold content of the high-grade gold system at the Surebet Discovery.
●
A total of 12 stacked gently dipping high-grade gold veins extend for 1.2 kilometers at the Surebet discovery, have been enhanced by four high-grade RIRG Eocene-aged dykes that are up to 25 meters wide and exposed along strike at surface for up to 1,500 meters have been discovered and modelled to date (see news release dated June 23, 2025).
●
The footprint of the mineralization discovered to date at Surebet is 1.8 km2 and remains open in all directions.
●
Thanks to the mountainous topography, mineralization in the veins is exposed on the surface for 2.1 km of strike (1.0 km on the south slope and 1.1 km on the north slope) with a vertical relief of 700 meters.
●
A study completed by the Colorado School of Mines confirms a new interpretation of the ore forming process of high-grade gold mineralization at Surebet and outlines a common magmatic source for the high-grade gold system, now in three distinct rock packages. Which gives the Surebet untapped discovery potential to increase tonnage and gold content in the various known rock packages. Until this study, researchers and explorers in the Golden Triangle had not recognized the high-grade gold discovery potential in the Eocene-aged RIRG dykes (see news release March 13, 2025), which is showing the potential that these discoveries could be a geological breakthrough in the Golden Triangle of British Columbia.
