• 100% of the drill holes completed to date on the Surebet Discovery have intersected substantial quartz-sulphide mineralization.
• The remarkable continuity, widths and grades demonstrated by drilling in multiple lodes shows this extensive 1.8 km² gold system continues to demonstrate strong potential to become one of the most significant gold discoveries in British Columbia’s Golden Triangle in many years. The strong results received to date will help vector in on drilling targets that remain open with excellent expansion potential.

• Of the holes drilled during the 2025 campaign, 83 out of 110 holes (or 76%) contained visible gold to the naked eye (VG-NE). 355 out of 386 drill holes representing 92% of holes drilled to date at Surebet contain VG-NE.

• High-grade gold has been identified in three distinct rock packages discovered to date at the Surebet Discovery. This includes the gently dipping gold-rich stacked quartz-sulphide breccias/stockwork veins; the gold-rich intermediate to felsic Eocene-aged dykes; and the recently discovered broad gold-rich zones of calc-silicate altered breccia. All mineralized rock types contain substantial amounts of VG-NE (from fine-grained to coarse-grained gold) and remain open for expansion. This confirms the presence of a Motherlode magmatic source nearby, a causative intrusion responsible for the extensive 1.8 km² high-grade gold system at Surebet.
• The fully funded 2026 drill program will be mainly focused on expanding the 5 Main Mineralized Zones. Data compilation and interpretation is underway which will be used to vector in on the indicated Motherlode causative intrusive source to this extensive high-grade gold system with widespread VG-NE that remains open for expansion.
• Gold-equivalent assay results which will include multi-element (Silver, Copper, Lead and Zinc) analyses for 56 out of 110 drill holes completed in 2025 are pending and will be released in the immediate future.

SUREBET DISCOVERY – UPDATED 3D MODEL (Click Here)

Goliath Resources Limited (TSX-V: GOT) (OTCQX: GOTRF) (FSE: B4IF) is pleased to report the completed gold-equivalent assay results for 54 out of 110 holes drilled in 2025 at the Surebet Discovery on its 100% controlled Golddigger Property, Golden Triangle, British Columbia. Accounting for Silver, Copper, Lead and Zinc within these 54 drill hole results, Goliath reports an average 13.2% increase in overall grade values from the previously announced Gold only assays (see news January 20, 2026, December 2, 2025, November 17, 2025, October 27, 2025, September 22, 2025, September 8, 2025, August 26, 2025, and July 28, 2025).

Highlights include drill hole GD-25-337, which intersected 10.83 g/t AuEq (10.60 g/t Au and 8.04 g/t Ag) over 22.82 meters, including 15.51 g/t AuEq (15.19 g/t Au and 11.14 g/t Ag) over 15.71 meters including 38.71 g/t AuEq or 1.24 oz/t AuEq (37.28 g/t Au 49.80 g/t Ag) over 3.36 meters in the Golden Gate Zone. Every drill hole completed so far within the 1.8 km² Surebet discovery, including all 110 holes from the 2025 season, has successfully intersected gold mineralization. These results confirm predictable continuity, grade, and width across 5 Gold-Rich Zones and 46 Distinct Lodes, all of which remain open for expansion. The fully funded 2026 drill program will focus on expanding the 5 Main Mineralized Zones, testing the Motherlode causative intrusive source, and build toward a future resource. Gold-equivalent assay results which will include multi-element (Silver, Copper, Lead & Zinc) analyses for 56 out of 110 holes drilled in 2025 are still pending and will be released in the immediate future.

Mr. Roger Rosmus, Founder & CEO of Goliath states: “We are very pleased to see a 13.2% increase to the overall AuEq grade numbers reinforcing the significance of the metals other than gold at the Surebet Discovery. What continues to stand out (and get better the more we drill) about the Surebet high-grade gold discovery is the widespread distribution of VG-NE, as can be seen in our map of the VG-NE in the drill holes. It is rare to see a discovery like this not only in the Golden Triangle, but worldwide. The vast number of stacked veins is analogous to the gold-rich Pogo Mine in Alaska. Modelling of the stacked veins shows a series dipping to the southwest (Surebet group) and to the southeast (Bonanza group) which open the possibility of two separate sources or one large one that could be several thousands of meters. Another interesting aspect is that the Surebet group and Bonanza group come together in a Hinge Zone that has a substantial block of rock with plenty of VG-NE. In addition to waiting for the remaining 56 gold-equivalent assays, we are also updating our models of the multitude of high-grade gold zones, advanced geological studies at the Colorado School of Mines to help us prepare for the 2026 drilling season. We have never been in a stronger balance sheet position as we are fully funded for the upcoming 2026 campaign. The bottom line is that we are in a unique position having an important high-grade gold discovery to expand upon in the greatest gold bull market ever.”

Assay results from the recently concluded 64,364-meter drill program have significantly expanded the high-grade footprint of the Surebet Discovery, which remains open for further growth. An updated geological model incorporating all 2025 data identifies 5 primary mineralized Zones: Bonanza, Surebet, Golden Gate, Whopper, and Eldorado. Collectively these Zones comprise 46 gold-rich lodes and associated Eocene-aged RIRG dykes.

Table 1: Five main modelled gold rich zones and dykes.

High-grade gold has been identified in three distinct rock packages discovered to date at the Surebet Discovery. This includes the gently dipping gold-rich stacked quartz-sulphide breccias/stockwork veins; the gold-rich intermediate to felsic gold-Rich dykes; and the recently discovered broad gold-rich zones of calc-silicate altered breccia. All mineralized rock types contain substantial amounts of VG-NE (from fine-grained to coarse-grained gold) and remain open for expansion. This confirms the presence of a Motherlode magmatic source nearby, a causative intrusion responsible for the extensive 1.8 km² high-grade gold system at Surebet.

The remarkable continuity, widths and grades encountered across multiple lodes underscore the significance of this 1.8 km² gold system which has strong potential to become one of the most significant gold discoveries in British Columbia’s Golden Triangle in many years. Success to date has effectively vectored toward several open targets, providing a strong foundation for further expansion in the 2026 drilling campaign.

Surebet Discovery Highlights

• Assay results are still pending for 56 holes from the 2025 exploration campaign for the gold equivalent (AuEq) values, that will be announced once received, compiled and interpreted.
• 83 out of 110 holes (or 76%) drilled in 2025 contain VG-NE, 100% of holes drilled to date at the Surebet Discovery have intersected substantial quartz-sulphide mineralization. See news releases dated: January 20, 2026, December 2, 2025, November 17, 2025, October 27, 2025, September 22, 2025, September 8, 2025, August 26, 2025, and July 28, 2025.
• 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. See news releases dated: July 7, 2025, June 23, 2025, January 7, 2025, January 13, 2025, February 10, 2025, February 18, 2025, February 27, 2025, December 12, 2024 and July 30, 2024.
• 92% of the holes (355 out of 386) drilled to date at Surebet contain VG-NE (see VG-NE heat map above).
• The best hole drilled to date is GD-24-260 previously reported and is now been modeled from the Golden Gate 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 third distinct rock package consisting of calc-silicate altered breccia is drill hole GD-25-337, which intersected 10.83 g/t AuEq (10.60 g/t Au and 8.04 g/t Ag) over 22.82 meters, including 15.51 g/t AuEq (15.19 g/t Au and 11.14 g/t Ag) over 15.71 meters including 38.71 g/t AuEq or 1.24 oz/t AuEq (37.28 g/t Au 49.80 g/t Ag) over 3.36 meters in the Golden Gate Zone. The intercept is approximately true width. More details on the QA/QC protocol can be found in the section titled “QA/QC Protocol” below.
• Multiple gently dipping gold-mineralized stacked veins have been identified every year on the Surebet high-grade gold discovery. Recent discoveries include gold-rich RIRG Eocene-aged dykes, Goldilocks Zones where the veins and vertical 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 characterized by calc-silicate altered breccia, which increases potential tonnage and gold content of the high-grade gold system at the Surebet Discovery.
• 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.
• Goliath has drilled over 156,000 meters encompassing over 1,500 pierce points in the Surebet Discovery located at the Golddigger property between 2021 and 2025.
• The Surebet Discovery has predictable continuity and good metallurgy with gold recoveries of 92.2% from gravity and flotation at a 327-micrometer crush including 48.8% free gold recovery from gravity alone (no cyanide required to recover the gold). The metallurgy completed to date shows a benign rock composition without deleterious elements (see news release March 1, 2023).
• Based on positive grassroots exploration and drill results in recent years, Goliath significantly increased its land package from 66,608 hectares to 91,518 hectares (226,146 acres) and now controls 56 kilometers of key terrain of the Red Line geologic trend providing for additional discovery potential.
• The Golddigger Property is located on tidewater with a barge route to Prince Rupert (190 km south) and close to infrastructure including the town of Kitsault adjacent to a permitted mine site on private property.

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 good 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 a well positioned 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.
