TORONTO, Ontario — February 24, 2026 — Leads & Copy —
Goliath Resources Limited (TSX-V: GOT) (OTCQX: GOTRF) (FSE: B4IF) has released the completed gold-equivalent assay results for the remaining 56 holes drilled in 2025 at the Surebet Discovery on its 100% controlled Golddigger Property in British Columbia’s Golden Triangle.
Accounting for silver, copper, lead and zinc within these 56 drill hole results, Goliath reports an average 19.6 % increase in overall grade values from these previously announced gold only assays, with numerous high-grade intercepts including 24.16 g/t AuEq over 7.00 meters.
According to Goliath Resources, 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.
Of the holes drilled during the 2025 campaign, 83 out of 110 holes (or 76%) contained visible gold to the naked eye. 355 out of 386 drill holes representing 92% of holes drilled to date at Surebet contain visible gold to the naked eye.
Highlights from drill results include:
Drill hole GD-24-280 (a 2024 hole relogged in 2025) intersected several intervals up to: 24.16 g/t AuEq (24.05 g/t Au and 5.78 g/t Ag) over 7.00 meters, within 17.32 g/t AuEq (17.24 g/t Au and 4.28 g/t Ag) over 10.00 meters, within 8.35 g/t AuEq (8.31 g/t Au and 2.30 g/t Ag) over 23.00 meters in the Bonanza Zone.

The company 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. Testing conducted on a composite core sample through a combination of simple gravity and flotation resulted in notable recoveries of 92.2% for Gold, 86.5% for Silver, 94.2% for Lead and 96.9% for Zinc. Recoveries with a crush size of 327 micrometer through simple and cost-effective gravity alone amounted to 48.8% for Gold and 10.3% for Silver (no cyanide leaching required to recover the gold and silver). The metallurgy completed to date shows a benign rock composition without deleterious elements.
Across all 110 drill holes completed during the 2025 season, this polymetallic contribution is an average increase of 16.5% in overall grade values from the gold only assays.
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.
Five main modelled gold rich zones and dykes:
Bonanza: 5 lodes, 1.8 km x 1.1 km x 19 m, 8.35 g/t AuEq over 23 m, Remains Open
Surebet: 9 lodes, 1.2 km x 930 m x 19 m, 21.08 g/t AuEq over 23 m, Remains Open
Golden Gate: 18 lodes, 1.3 km x 820 m x 14 m, 34.52 g/t AuEq over 39 m, Remains Open
Whopper: 12 lodes, 800 m x 450 m x 6 m, 32.67 g/t AuEq over 4 m, Remains Open
Eldorado: 2 lodes, 680 m x 700 m x 5 m, 13.93 g/t AuEq over 5.75 m, Remains Open
Gold-rich dykes: 1.4 km x 890 m x 25 m, 12.03 g/t AuEq over 10 m, Remains Open
Mr. Roger Rosmus, Founder & CEO of Goliath states: “We are delighted with the substantial increase in grades on a gold equivalent basis (increase of 16.5% with all metals included) in our 110 holes from 2025 as well as the expanded model. It is positive that after 386 holes drilled that the various gently-dipping stacked veins, and vertical dykes, remain open. We believe that we are still likely at the top of the system with a substantial amount of room to grow laterally and at depth. What has clearly emerged from our drilling to date is that an analogue for the gently-dipping stacked veins is the high-grade Pogo Mine in Alaska. Advancing the Surebet high-grade gold discovery, at a time when gold is near record highs, and the majors and mid-tiers have large cash positions on their balance sheets and in need of growth opportunities while there is a dearth of them, puts us in a unique position. I would like to point readers to the images that show the expanded model of the stacked veins and vertical dykes, plus the image with the widespread VG-NE to get a sense of the impressive discovery Surebet is standing at to date and remains wide open for expansion. In addition, I would invite our shareholders and potential shareholders to compare Surebet to other discoveries and believe they will reach the conclusion that Surebet is one of very few such discoveries anywhere in the world. Now we are in the process of compiling all of our data, adjusting our models, doing advanced geological studies at the Colorado School of Mines, to assist our geological team in planning for the upcoming 2026 drilling season. We look forward to mobilizing later this year for our fully-funded 2026 drilling campaign.”
Dr. Quinton Hennigh, Geologic & Technical Advisor to Crescat Capital, a strategic investor in Goliath, states: “At the start of the 2025 Surebet drill campaign, the objectives were clear: continue to expand the known lode system and systematically drill areas with high-grade mineralization to better define these key areas. With all assay results now in hand, we can easily say these objectives were met. The current Surebet lode model is significantly expanded compared to last year, and the definition of high-grade regions within each lode is now much clearer. The key take away from this year’s drilling is that the system continues to display considerable opportunity for expansion. I have noticed that the most successful discoveries are ones that continue to expand and improve over time which is certainly the case at Surebet.”
Accounting for Silver, Copper, Lead and Zinc within these 56 drill hole results, Goliath reports an average 19.6 % increase in overall grade values from these previously announced Gold only assays, with numerous high-grade intercepts including 24.16 g/t AuEq over 7.00 meters. Across all 110 drill holes completed during the 2025 season, this polymetallic contribution is an average increase of 16.5% in overall grade values from the Gold only assays.
92,000 meters of drilling completed in four drilling seasons (2021-2024) on the Surebet Discovery resulted in the modeling of a vast stacked vein system. The 2025 drilling season alone with more than 64,000 meters of drilling has expanded the modelled stacked vein system that remains open; over 156,000 meters drilled to date. This demonstrates the continuity of this high-grade gold system and the remaining untapped expansion potential of the Surebet discovery for 2026 and beyond.
100% of the drill holes completed to date on Surebet have intersected gold mineralization clearly demonstrating desirable continuity, grades, and widths inclusive of over 1,500 pierce points within 5 Main Gold-Rich Zones comprising 46 mineralized lodes that remain open for expansion. 100% of the drill holes completed to date on the Surebet Discovery have intersected substantial quartz-sulphide mineralization.
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 visible 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 visible gold that remains open for expansion.
The desirable continuity, widths and grades demonstrated by drilling in multiple lodes shows this extensive 1.8 km2 gold system continues to demonstrate the potential to become one of the most significant gold discoveries in British Columbia’s Golden Triangle in many years. The positive results received to date will help vector in on drilling targets that remain open for expansion potential.
