Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) is very pleased to announce positive assay results from drill hole GD-25-317 which assayed 3.17 g/t Au over 18.73 meters, including 5.10 g/t Au over 11 meters, including 11 g/t Au over 4.85 meters within the Bonanza Zone that remains wide open at Surebet on the 100 % controlled Golddigger Property, Golden Triangle, British Columbia. An additional gold-rich interval in the same hole consists of 3.64 g/t Au over 9.40 meters, including 6.02 g/t Au over 5.50 meters part of the Surebet Zone.
Two intervals of high-grade gold mineralization were also intersected in drill hole GD-25-302 that assayed 2.26 g/t Au over 19.00 meters, including 6.28 g/t Au over 6.00 meters, including 8.88 g/t Au over 4.00 meters, and 1.59 g/t Au over 16.00 meters, including 3.44 g/t Au over 6.00 meters. These new intervals extend the footprint of high-grade gold mineralization of the Bonanza Zone to the south by 150 meters increasing the resource potential of this zone that remains wide open, confirming the additional discovery potential for high-grade gold mineralization at the Surebet Discovery.
The Company has completed 25,000 meters of drilling (out of 60,000 meters planned and fully funded for 2025), with 100% of the drill holes intersecting substantial quartz-sulphide mineralization as well as 94 % of the holes contain gold visible to the naked eye. The reported assays reflect gold only (AuEq value in interval will be adjusted accordingly once Ag, Cu, Pb and Zn are received).
Mr. Roger Rosmus, Founder & CEO of Goliath states: “Receiving exceptional gold only assays of 3.17 g/t Au over 18.73 meters, including 5.10 g/t Au over 11 meters, including 11 g/t Au over 4.85 meters from the first new holes completed in 2025 is a testament to the strong high-grade gold potential at Surebet. With 100% of drill holes completed this year intersecting mineralization, as well as 94% of the holes containing gold visible to the naked eye, we are on track to complete the most ambitious drill program on Surebet to date with 25,000 meters completed and 35,000 meters to go for a total of 60,000 meters that is fully funded. We are looking forward to releasing additional assay results and updating the gold-equivalent (AuEq) hole results as they become available.”
Drill hole GD-25-317 intersected 5 occurrences of gold visible to the naked eye (“VG”) hosted in veins that are part of a quartz-stockwork in sandstone units containing moderate amounts of sulphides such as sphalerite, galena and pyrrhotite. A 27.68 meter interval with high-density of quartz-sulphide veining from 332.88 meters to 360.56 meters contains 2 occurrences of visible gold at 355.90 meters and 359.47 meters from the Surebet Zone. Another 19.83 meter interval from 441.90 meters to 461.73 meters contains multiple quartz-sulphide veins up to 50 cm wide with 2 occurrences of visible gold at 457.02 meters and 459.66 meters from the Bonanza Zone. Additional VG was identified at 256.90 m. The new intercept is located 180 meters to the northeast of drill hole GD-24-260, the highest grade gold interval drilled on Surebet to date, which assayed 34.52 g/t AuEq or 1.11 oz/T AuEq (34.47 g/t Au and 3.96 g/t Ag) over 39.00 meters including 132.93 g/t AuEq or 4.27 oz/T AuEq (132.78 g/t Au and 12.98 g/t Ag) over 10.00 meters, and 166.04 g/t AuEq or 5.34 oz/T AuEq (165.84 g/t Au and 16.07 g/t Ag) over 8.00 meters within an interval composed of altered andesite with substantial quartz-sulphide veining (see news January 13, 2025). Drill hole GD-25-302 intersected 6 occurrences of VG over a 96.50 meter interval from 89.50 meters to 186.00 meters within an altered andesite unit with high density quartz-sulphide veining corresponding to the Bonanza Zone that remains open. The new intercept is located 420 meters to the east of drill hole GD-24-260.

High-grade gold mineralization has been confirmed in three distinct rock packages at the Surebet Discovery, which include: gently-dipping gold-rich mineralized stacked veins; gold-rich intermediate to felsic Eocene-aged RIRG dykes that crosscut the veins; and the broad zones of calc-silicate altered breccia. All three rock packages contain substantial amounts of VG and remain wide open, which strongly indicates the presence of a Motherlode magmatic causative source at depth responsible for the widespread high-grade gold mineralization at the Surebet Discovery.

The 2025 planned campaign is under way and consists of 60,000 meters (recently increased from 40,000 meters) of systematic drilling with 9 drill rigs. The campaign aims at expanding the full geometry of the Surebet discovery laterally and to depth. 100% of the drilling will be focused on the Surebet Discovery, where the Company has designed a detailed drill plan that will consist of: testing for the Motherlode Magmatic intrusive gold source; testing an additional 13 Eocene-aged dykes observed on the surface that have never been drill tested for RIRG mineralization; infill drilling with the goal of increasing pierce points density in all known stacked veins with a particular focus on the highest-grade areas from the Bonanza Zone and Surebet Zone intersection domain; testing zones where the RIRG dykes and gently dipping veins crosscut which are being called Goldilocks Zones as they are key locations where there are two styles of gold mineralization enriching the zones; and expanding the known mineralized veins laterally and to depth where they currently remain open.
2025 re-logging initiative
Recently released results from the re-logging of holes drilled between 2021 – 2024 include a new interval from drill hole GD-22-64 (see news June 23, 2025) comprising a Reduced Intrusion Related Gold dyke believed to be directly related to the Motherlode feeder source that contained gold visible to the naked eye and assayed 6.31 g/t AuEq over 14.35 meters including 11.36 g/t AuEq over 7.85 meters, as well as drill hole GD-24-280 (see news July 7, 2025), which assayed 8.31 g/t Au over 23.00 meters, including 15.69 g/t Au over 11 meters, including 37.45 g/t Au or 1.20 oz/T over 4 meters hosted in the calc-silicate altered breccia within the high-grade gold Bonanza Zone.
From the early season re-logging initiative, assays are pending for an additional 6 drill holes containing VG associated with RIRG dykes, calc-silicate altered breccias and known stacked veins, including:

Surebet Discovery Highlights
About Golddigger Property
The Golddigger Property is 100% controlled and covers an area of 91,518 hectares in a highly prospective geological setting of the Eskay Rift, within 3 kilometers of the Red Line in the Golden Triangle of British Columbia. This area, in close proximity to the Red Line, has hosted some of Canada’s greatest gold mines including Eskay Creek, Premier and Snip. Other significant and well-known deposits in the Golden Triangle include Brucejack, Copper Canyon, Galore Creek, Granduc, KSM, Red Chris, and Schaft Creek. Goliath controls 56 kilometers of the Red Line which is a geologic contact between Triassic age Stuhini rocks and Jurassic age Hazelton rocks used as key markers when exploring for gold-copper-silver mineralization.
The Surebet discovery has predictable continuity and excellent metallurgy with gold recoveries from gravity and flotation at a 327-micrometer crush of 92.2% including 48.8% free gold from gravity alone (no cyanide required to recover the gold). The metallurgy completed to date shows no deleterious elements are present (see news release dated March 1, 2023).
The Property is in an excellent location in close proximity to the communities of Alice Arm and Kitsault where there is a permitted mill site on private property. It is situated on tide water with direct barge access to Prince Rupert (190 kilometers via the Observatory inlet/Portland inlet). The town of Kitsault is accessible by road (190 kilometers from Terrace, 300 kilometers from Prince Rupert) and has a barge landing, dock, and infrastructure capable of housing at least 300 people, including high-tension power.
Additional infrastructure in the area includes the Dolly Varden Silver Mine Road (only 7 kilometers to the East of the Surebet discovery) with direct road access to Alice Arm barge landing (18 kilometers to the south of the Surebet discovery) and high-tension power (25 kilometers to the east of Surebet discovery). The city of Terrace (population 16,000) provides access to railway, major highways, and airport with supplies (food, fuel, lumber, etc.), while the town of Prince Rupert (population 12,000) is located on the West Coast of British Columbia and houses an international container seaport also with direct access to railway and an airport.
