Mr. Roger Rosmus reports

GOLIATH REPORTS MULTIPLE HOLES UP TO 7.38 G/T AUEQ OVER 35.7 METERS, INCLUDING 19.51 G/T AUEQ OVER 8.32 METERS AT THE HIGH-GRADE GOLD SUREBET DISCOVERY THAT REMAINS OPEN FOR EXPANSION, GOLDEN TRIANGLE, B.C.

Goliath Resources Ltd. has released assay results for drill holes GD-26-414, GD-26-426, GD-26-431 and GD-26-436 from the Surebet zone on its 100-per-cent-owned Golddigger property in the Golden Triangle in British Columbia.

Roger Rosmus, founder and chief executive officer of Goliath, stated: "Here we go again; Surebet just keeps passing the test we set out with in the 2026 drilling season. We wanted to step out aggressively to see if Surebet can keep delivering high-grade gold with large stepouts. Instead of cutting anything off, the overall system just keeps getting bigger and bigger as we test it with aggressive stepout holes. Of particular note, in this news release we are delighted to report some significant widths and grades from multiple holes. I have never seen a high-grade gold system that keeps delivering such remarkable high-grade gold with such a large footprint. Our team is firing on all cylinders, Surebet is passing every test, and we are eager to see additional drilling results that keep showing Surebet is one of the most important high-grade gold discovery in the Golden Triangle in many years."

Drill hole GD-26-436 from the Surebet zone intersected an extensive mineralized interval near surface that assayed 7.38 grams per tonne gold equivalent over 35.7 metres, including 19.51 g/t AuEq over 8.32 metres. This entire interval is characterized by veining, alteration and anomalous gold grades throughout its length with multiple high-grade subintervals. It also has several occurrences of visible gold to the naked eye (VG-NE), native silver associated with galena, sphalerite, pyrrhotite and chalcopyrite in quartz-sulphide stockwork and breccia hosted in sandstones.

Drill hole GD-26-426 intersected two neighbouring mineralized splays of the Surebet zone. The first assayed 5.18 g/t Au over 4.50 metres, within a wider interval of 2.81 g/t Au over 9.00 metres. The second assayed 7.85 g/t Au over 3.00 metres within a wider interval of 4.22 g/t Au over 5.80 metres. Mineralization consists of breccia and stockwork with VG-NE associated with massive to stringer galena, sphalerite and pyrrhotite (Au only; AuEq assays pending).

Drill hole GD-26-431 intersected the Eldorado zone, which assayed 5.83 g/t Au over 5.95 metres, including 11.42 g/t Au over 2.90 metres, within a wider interval of 3.07 g/t Au over 11.90 metres. Mineralization occurs as disseminated and stringer pyrrhotite and pyrite in stockwork veins and veinlets hosted in sandstone and associated with sericite and biotite alteration.

Additional mineralized intercepts reported in this news release include drill hole GD-26-421 (Pad 4, azimuth of 60 degrees, dip of 72 degrees), which intersected 2.02 g/t AuEq over 3.98 metres, including 7.68 g/t AuEq over 0.98 metre, and the integration of the previously reported gold only grades with multielement assay results for drill hole GD-26-424 (Pad 1, azimuth of 115 degrees, dip of 81 degrees), which intersected 10.90 g/t AuEq over 6.00 metres, including 16.48 g/t AuEq over 3.96 metres, including 35.65 g/t AuEq over 1.82 metres.

All drill holes completed during the 2026 drill program have intersected quartz-sulphide mineralization, which typically coincides with high-grade gold mineralization. Fifty-two out of 98 planned drill holes have been completed with a total of 31,994 metres drilled thus far in 2026.

Surebet discovery highlights:

• One hundred per cent of the drill holes completed prior to the 2026 drill season have intersected gold mineralization, clearly demonstrating remarkable grade continuity and widths, with over 1,500 drill hole pierce points; approximately 77 per cent of these pierce points have 25- to 50-metre spacings.
• The most recent ore mineralization model incorporating all available data prior to the 2026 drill program identified five stacked gold-mineralized vein systems/zones: Bonanza, Surebet, Golden Gate, Whopper and Eldorado. Collectively, these zones comprise 46 gold-rich lodes/veins and multiple subvertical Eocene-aged dike swarms.

• Three hundred fifty-five out of 386 drill holes representing 92 per cent of holes drilled between 2021 and 2025 at Surebet contain VG-NE.
• High-grade gold has been identified in three distinctive rock types, including: quartz-sulphide breccias and stockwork veins hosted in the sedimentary units, precious-and-base-metal-bearing veins hosted in the volcanic units, and intermediate to felsic Eocene-aged dikes. All mineralized rock types contain substantial amounts of VG-NE (from fine-grained to coarse-grained gold) and remain open for expansion.
• Metallurgical testing conducted on a composite core sample resulted in metal recoveries of 92.2 per cent for gold, 86.5 per cent for silver, 94.2 per cent for lead and 96.9 per cent for zinc achieved through a combination of simple gravity and flotation circuits. The gravity-only recoveries amount to 48.8 per cent Au and 10.3 per cent Ag with a crush size of 327 micrometres (no cyanide leaching required to recover the gold and silver). The metallurgical testing completed to date shows a benign rock composition without deleterious elements (see news release March 1, 2023).
• The consistent continuity, widths and grade of ore mineralization demonstrated by greater than 156,000 metres of drilling in multiple stacked lodes/veins confirms that the 1.8-square-kilometre Surebet discovery continues to demonstrate strong potential to become one of the most significant high-grade gold discoveries in British Columbia's Golden Triangle in many years.
• Ninety-two per cent of the holes (355 out of 386) drilled prior to the 2026 drill season at Surebet contain VG-NE and 100 per cent of holes drilled to date at the Surebet discovery have intersected substantial quartz-sulphide mineralization.

• The best hole drilled to date from the gold-rich stacked quartz-sulphide breccias and stockwork veins hosted in the sedimentary units is GD-23-157, which assayed 21.08 g/t AuEq (18.95 g/t Au and 95.31 g/t Ag) over 23.00 metres, including 33.75 g/t AuEq (30.39 g/t Au and 150.42 g/t Ag) over 14.00 metres, including 50.27 g/t AuEq (45.27 g/t Au and 225.42 g/t Ag) over 9.00 metres (see news release dated Aug. 15, 2023).
• The best hole drilled to date from the precious-and-base-metals-bearing veins hosted in the volcanic units is GD-24-260 from the Golden Gate zone, which assayed 34.52 g/t AuEq (34.47 Au and 3.96 Ag) over 39.00 metres, including 132.93 g/t AuEq (132.78 Au and 12.98 Ag) over 10.00 metres, and 166.04 g/t AuEq (165.84 Au and 16.07 Ag) over 8.00 metres (see news release dated Jan. 13, 2025).
• The best hole drilled to date from the Eocene-aged dikes is GD-22-58, which assayed 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10.00 metres, including 19.91 g/t AuEq (19.62 g/t Au and 25.61 g/t Ag) over 6.00 metres, including 23.82 g/t AuEq (23.47 g/t Au and 30.54 g/t Ag) over 5.00 metres, plus a second separate interval downhole of 8.59 g/t AuEq (8.35 g/t Au and 20.74 g/t Ag) over 5.00 metres (see news release dated March 13, 2025).
• The best hole drilled to date from the Eocene-aged dikes is GD-22-58, which assayed 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10.00 metres, including 19.91 g/t AuEq (19.62 g/t Au and 25.61 g/t Ag) over 6.00 metres, including 23.82 g/t AuEq (23.47 g/t Au and 30.54 g/t Ag) over 5.00 metres, plus a second separate interval downhole of 8.59 g/t AuEq (8.35 g/t Au and 20.74 g/t Ag) over 5.00 metres (see news release dated March 13, 2025).
• A study completed by the Colorado School of Mines confirms a new interpretation of the ore-forming process at Surebet and suggests a common magmatic source for the high-grade gold system hosted in three distinct rock types. Until this study, researchers and explorers in the Golden Triangle had not recognized the high-grade gold discovery potential in the Eocene-aged dikes (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.
• 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 kilometres of the Red Line geologic trend providing for additional discovery potential.
• The Golddigger property is located adjacent to tidewater with a barge route to Prince Rupert (190 kilometres south) and close to existing infrastructure, including the town of Kitsault, proximal to a permitted mine site on private property.

About the Golddigger property

The Golddigger property is 100 per cent owned and covers an area of 91,518 hectares in a highly prospective geological setting of the Eskay rift, within three kilometres of the Red Line in the Golden Triangle of British Columbia. This area 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 kilometres 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 shown predictable continuity and good metallurgy with gold recoveries of 92.2 per cent from gravity and flotation at a 327-micrometre crush, including 48.8 per cent recovery of free gold from gravity alone (no cyanide required to recover the gold). The metallurgical testing completed to date shows no presence of deleterious elements (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 adjacent to tidewater, with direct barge access to Prince Rupert (190 kilometres through the Observatory inlet/Portland inlet). The town of Kitsault is accessible by road (190 kilometres from Terrace and 300 kilometres 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 seven kilometres to the east of the Surebet discovery), with direct road access to Alice Arm barge landing (18 kilometres to the south of the Surebet discovery) and high-tension power (25 kilometres to the east of Surebet discovery). The city of Terrace (population of 16,000) provides access to railway, major highways and airport with supplies (food, fuel and lumber), while the town of Prince Rupert (population of 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.
