Goliath Drills Several Holes Of High-Grade Gold Up To 10.25 g/t Au Over 7.02 Meters Within 5.20 g/t Au Over 15.00 Meters From 281m To 296m Downhole, Surebet Discovery Remains Open, Golddigger Property, Golden Triangle, B.C.

• 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.

• Drill hole GD-25-377 intersected three separate intervals. The first being 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 intercept is 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 an interval that assayed 8.73 g/t Au over 3.80 meters. The 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); see image below.

• 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. 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); see image below.

• 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. 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); see image below.

• 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. 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); see image 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.

Toronto, Ontario – November 17, 2025 – Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) (the “Company” or “Goliath”) 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 quartzsulphide veining hosted in the Bonanza Zone that remains open at the Surebet Discovery on its 100% controlled Golddigger Property (the “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.

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.
