Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) is pleased to announce additional assay results from its 2025 drill program where drill hole GD-25-377 intersected three separate mineralized intervals up to 10.25 g/t Au over 7.02 meters, within 7.16 g/t Au over 10.84 meters, within 5.20 g/t Au over 15.00 meters containing multiple occurrences of VG-NE within a zone of strong quartz-sulphide veining hosted in the Bonanza Zone that remains open at the Surebet Discovery on its 100% controlled Golddigger Property, Golden Triangle, British Columbia. Assay results from the Surebet Discovery continue to confirm desirable widths and grades with consistent continuity. These results have extended the high-grade core by 80 meters to the NW for a total of 580 meters and remains open. Remaining drill results from the 2025 drill season have strong potential to continue to provide desirable widths and grades and continuity as observed thus far.

• Assays are still pending for 80 holes from this year’s exploration campaign, of which 62 (representing 78% of the total pending) contain visible gold to the naked eye (VG-NE); see images & table 1. below.

• Drilling was focussed on expanding the system as well as continue to increase the confidence level at the Surebet Discovery confirming desirable widths, grades and continuity. The results today have extended the high-grade domain by 80 meters to the NW for a total of 580 meters on the Goldzilla Vein and remains open (see plan view above).
• 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 Reduced Intrusive Related Gold (RIRG) 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 at depth, a causative intrusion responsible for the extensive 1.8 km² high-grade gold system at Surebet.
• The completed and fully funded 2025 drill campaign significantly exceeded the initial plans of 40,000 meters for a total of 64,364 meters of systematic drilling with 9 drill rigs. 100% of the drilling was focused on the Surebet Discovery, where the Company designed a detailed campaign that tested for the Motherlode intrusive gold source, the mineralized RIRG Eocene-aged dykes, infill drilling within the known stacked veins, as well as expanding the known mineralized veins laterally and to depth.
• 100% of the drill holes completed to date on Surebet have intersected substantial quartz-sulphide mineralization. VG-NE was observed in 83 drill holes out of 110 (or 76%) completed in 2025. See news releases dated: October 27, 2025, September 22, 2025, September 8, 2025, August 26, 2025, and July 28, 2025.
• 92% of the holes (355 out of 386) drilled to date at the Surebet Discovery contain VG-NE (see heat map below).

• The Surebet Discovery has widespread drill holes representing more than 600 pierce points over an area of 1.8 km², returning high metal values showing it has the potential to be an important grassroots high-grade gold discovery in the Golden Triangle.

100% of the drill holes completed to date on Surebet have intersected substantial quartz-sulphide mineralization as well as 83 of the 110 drill holes (or 76%) from 2025 contain gold visible to the naked eye (VG-NE) clearly demonstrating the discovery potential remaining on the property.

Assays are still pending for 80 holes from this year’s exploration campaign, of which 62 (representing 78% of the pending holes) contain VG-NE (see images above).

Mr. Roger Rosmus, Founder & CEO of Goliath states: “The Surebet high-grade gold discovery continues to consistently deliver good assay results, which clearly shows continuity and predictability. Particularly noted by the vast distribution of VG-NE in drill holes spanning an area for over 1,200 metres from northwest to southeast, over 1,000 meters from northeast to southwest and over 800 meters of vertical relief. Within that area are a series of gently dipping stacked veins that dip to the southwest, and another series of gently dipping stacked veins that dip to the southeast. They remain open in the down dip direction of both, suggesting that both could have separate sources feeding each series of stacked veins that would be over 4,000 metres apart. Or one magmatic event that is feeding from either side of it. Equally as impressive are the vertical RIRG dykes coming up through stacked veins, which suggests that there is a magma chamber below the entire mineralized area. At the intersections of the gently dipping veins and the vertical RIRG dykes (called Goldilocks zones) there are two temperature regimes for the VG-NE enriching the zones. Plus, we have found VG-NE within a third rock package with minimal drilling into those zones. Collectively, it is apparent that we are nowhere near the limits of the system, in fact, there is a good chance that we may only be halfway down the various zones with plenty more room to grow the system. Our team looks forward to receiving the assays from remaining holes so we can update the 3D model.”

Drilling was focused on expanding the Surebet high-grade gold discovery and has intersected high-grade gold mineralization in multiple drill holes along 580 meters of strike, delineating broad zones of high-grade gold mineralization within the Surebet-Bonanza intersection domains as well as the Goldzilla Vein confirming desirable grades, widths and continuity as demonstrated by drill results to date.

Drill hole GD-25-377 intersected three separate intervals. The first assayed 10.25 g/t Au over 7.02 meters, within 7.16 g/t Au over 10.84 meters, within 5.20 g/t Au over 15.00 meters containing multiple occurrences of VG-NE within a zone of strong quartz-sulphide veining hosted in the Bonanza Zone that remains open. The second intersected a broad interval of the Bonanza Zone that remains open and assayed 1.06 g/t Au over 30.00 meters, including 1.45 g/t Au over 20.04 meters, including 2.34 g/t Au over 9.01 meters, as well as a third interval that assayed 8.73 g/t Au over 3.80 meters. Drill hole GD-25-332 intersected 13.38 g/t Au over 5.75 meters, including 15.83 g/t Au over 4.86 meters, including 19.87 g/t Au over 3.87 meters part of a zone of quartz-sulphide veining containing multiple occurrences of VG-NE hosted in in the Goldzilla Vein that remains open. Drill hole GD-25-380 intersected 6.61 g/t Au over 5.80 meters, within 4.83 g/t Au over 8.00 meters from an interval corresponding to the Goldzilla Vein containing VG-NE in quartz-sulphide veins. Drill hole GD-25-374 intersected 4.59 g/t Au over 8.00 meters, including 5.21 g/t Au over 7.00 meters, including 8.89 g/t Au over 3.00 meters from a zone of strong quartz-sulphide stockwork part of the Surebet Zone containing multiple occurrences of VG-NE.

All intercepts are 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). The gold grades, coupled with VG-NE within substantial quartz-sulphide veins, stockworks, and breccias, which are mineralized with sphalerite, pyrrhotite, and chalcopyrite, highlight the potential for further expansion.

Table 1: Collar information for VG-NE drill holes reported in this news release.

Table 2: Assay highlights from 2025 drill holes reported in this news release.

High-grade gold mineralization has been confirmed in three distinct rock packages at the Surebet Discovery, which include: gently dipping gold-rich mineralized stacked quartz-sulphide breccias/stock work 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-NE (from fine-grained to coarse-grained gold) and remain 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.

Table 3: Collar information for assayed drill holes reported in this news release.

The 2025 drill consisted of 64,364 meters of systematic drilling with 9 drill rigs. The campaign was aimed at expanding the geometry of the Surebet Discovery laterally and to depth. 100% of the drilling was focused on the Surebet Discovery. The Company designed a detailed drill plan that consisted of: testing for the Motherlode Magmatic intrusive gold source; testing an additional 13 Eocene-aged dykes observed on the surface that had 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.

• 83 out of 110 holes (or 76%) drilled in 2025 contain VG-NE and 100% of drill holes have intersected substantial quartz-sulphide mineralization. Assays are still pending for 80 holes from this year’s exploration campaign, of which 62 (representing 78% of the total pending) contain visible gold to the naked eye (VG-NE). See news releases dated: 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 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). ).

• 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). ). 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 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.
• Goliath has drilled over 156,000 meters with over 600 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.
