The total footprint of the Surebet system is 2.01 km2, which represents a 12% increase compared to 1.8 km2defined prior to the 2026 drilling season; see news August 24, 2026. Goliath’s 2026 drilling successfully expanded Bonanza Zone From 1.27 km2to 1.51 km2. It intersected mineralization in multiple step-out drill holes, resulting in theexpansion of the Bonanza Zone by 750 meters to the southwest, 100 meters to the west, 100 meters to the north and 160 meters to the northeast side of the Surebet system and still remains open for expansion; see Figure 3.

Goliath’s 2026 drilling successfully expanded the Golden Gate Zone from 0.85 km2To 1.17 km2. It intersected mineralization in multiple step-out drill holes, resulting in theexpansion of the Golden Gate Zone by 480 meters to the northeastern side and 540 meters to the southwestern side of the Surebet system; see Figure 4.

The largest helicopter supported drill program in challenging alpine terrain in North America this year has officially come to an end. The throughput was much higher this year even in less than ideal weather conditions and a delayed start due to challenging snow levels compared to the 2025 drill program;a true testament to the leadership and team’s strength. 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 metals bearing veins hosted in the volcanic units; and intermediate to felsic Eocene-aged dykes.All of which contain substantial amounts of VG-NE (from fine-grained to coarse-grained gold) and remain wide open for expansion. This supports thepresence of a Motherlode magmatic source at depth, a causative intrusion responsible for the extensive 2.01 km2high-grade gold system at Surebet. The Surebet Discovery is a grassroots project that has evolved from the idea of exploring prospective untouched ground in an area recently exposed by glacial retreat and snowpack abatement, to a mineralizing system consisting of46 stacked gold-rich veins defined through over 200,000 meters of drilling, in a total of 21 months of work on the ground. The Surebet Discovery has widespread drill holes representing more than 1,500 pierce points (2021-2025) with a vast majority having 25 – 50 meter spacings that would most likely fall into the measured and indicated categories. The Company wishes to extend its sincere gratitude to Goliaths senior exploration consultant and project manager Mr. Bill Chornobay for his vision and his entire team for their tireless efforts since 2017. Bill is the founder, team builder, manager and financer of the syndicate responsible for generating, prospecting and staking the Golddigger property including the original Surebet discovery, which was subsequently optioned to Goliath Resources.

TORONTO, Sept. 22, 2026 (GLOBE NEWSWIRE) -- Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) (the“Company” or“Goliath”) is pleased to announce that the 2026 drill program has concluded with over 48,000 meters drilled in 97 holesat the Surebet Discovery on its 100% owned Golddigger Property (the “Property”), Golden Triangle, British Columbia. The program confirmed the continuity of this large, high-grade, gold-rich system. 100% of the drill holes completed to date on Surebet have intersected quartz-sulphide mineralization, as well, 412 drill holes out of 483 or 85% contain VG-NE, clearly demonstrating the untapped discovery potential remaining on the property. Assays are still pending for 83 holes drilled in 2026.

Mr. Roger Rosmus, Founder & CEO of Goliath states:_“Goliath is extremely fortunate to have the guidance and tireless support provided by Mr. Bill Chornobay along with his talented team over many years. They once again successfully completed a significant undertaking in a very short window this year under many adverse conditions including weather and snowpack to mention a few. Under Bill’s guidance, Goliath was able to meet many of its exploration goals over the years including this year and we look forward to another successful year in 2027 under his leadership. The list of people that contributed to the success at Surebet is long, which we are grateful for their tireless efforts that continue to unlock the full potential of the Surebet Discovery. I believe we are nowhere near the limits of this high-grade gold system. As stated many times, the more we drill the bigger the system gets and believe Surebet will be the most significant high-grade gold discoveries in British Columbia’s Golden Triangle in many years. We look forward to releasing further assay results as they are received, interpreted and compiled.”_

The 2026 drill program has concluded with over 48,000 meters drilled in 97 holes accomplished in a very short window despite the weather conditions, for a total of over 200,000 meters drilled since the maiden drill program in 2021. This was accomplished with 7 drill rigs in what we understand is one of North America's largest helicopter-supported drill programs in challenging alpine terrain this year. It is remarkable that 100% of all holes drilled to date have intersected the targeted quartz-sulphide mineralization, 59% of the holes completed in 2026 contain VG-NE and 85% of all 483 holes drilled contain VG-NE. This underscores the excellent predictability and expansive nature of the Surebet discovery that remains open.

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 metals bearing veins hosted in the volcanic units; and intermediate to felsic Eocene-aged dykes. All mineralized rock types contain substantial amounts of VG-NE (from fine-grained to coarse-grained gold) and remain open for expansion. These findings suggest the presence of a large-scale, multi-phased high-grade gold mineralizing event driven by a Motherlode causative intrusion at depth responsible for the extensive 2.01 km2high-grade gold system at Surebet that remains open.

In just 21 months of on-the-ground work, the Surebet Discovery has advanced from a grassroots showing on virgin ground exposed by glacial and snowpack retreat, to an extensive high-grade gold mineralizing system with significant potential. The project now consists of 46 identified stacked gold-rich veins defined by over 200,000 meters of total drilling. The system's scale continues to get larger with every drill program, with over 1,500 pierce points (2021 – 2025) distributed across an area of 2.01 km². The consistent high-grade gold results have drawn comparisons to some of the most significant discoveries in the Golden Triangle.

The Company is actively updating its high-grade gold wireframe models as assay results are received. Once all data from the 2026 program has been received, compiled, and modelled, a comprehensive drill plan for the 2027 season will be designed.

Surebet Discovery Highlights

100% 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 diamond drill hole intercepts (pierce points 2021 - 2025); ~77% have 25 – 50 meter spacings. Demonstrating the geological team has a great understanding of the system and its predictability.

The consistent continuity, widths and grade of ore mineralization demonstrated by >200,000 meters of drilling in multiple stacked lodes/veins confirms that the 2.01 km2Surebet Discovery continues to demonstrate strong potential to become one of the most significant high-grade gold discoveries in British Columbia’s Golden Trianglein many years.

The most recent ore mineralization model incorporating all available data prior to the 2026 drill program identified five (5) 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 dyke swarms. A good analogy for the stacked veins that are gently-dipping is the Pogo Mine in Alaska. (see Table 3 and Figure 6).

85% of the holes (412 out of 483) drilled to date at the Surebet Discovery contain VG-NE and 100% have intersected quartz-sulphide mineralization. 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, July 30, 2024, January 20, 2026, December 2, 2025, November 17, 2025, October 27, 2025, September 22, 2025, September 8, 2025, August 26, 2025, July 28, 2025, July 15, 2026, August 6, 2026, August 10, 2026, August 11, 2026, August 21, 2026, August 24, 2026, August 31, 2026, September 10, 2026, September 16, 2026 and September 18, 2026; see Figure 2 above.

Metallurgical testing conducted on a composite core sample resulted in metal recoveries of 92.2% for Au, 86.5% for Ag, 94.2% for Pb and 96.9% for Zn achieved through a combination of simple gravity and flotation circuits. The gravity-only recoveries amount to 48.8% Au and 10.3% Ag with a crush size of 327 micrometer(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 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 that assayed 21.08 g/t AuEq (18.95 g/t Au and 95.31 g/t Ag) over 23.00 meters, including 33.75 g/t AuEq (30.39 g/t Au and 150.42 g/t Ag) over 14.00 meters, including 50.27 g/t AuEq (45.27 g/t Au and 225.42 g/t Ag) over 9.00 meters(see news release dated August 15, 2023). 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 precious and base metals bearing veins hosted in the volcanic units is GD-24-260 from the Golden Gate Zone that 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 Big Bulk Zone, previously reported as the volcanic wedge zone, is GD-24-291 that assayed 1.97 g/t AuEq (1.92 Au and 1.85 Ag) over 33 meters(see news release dated August 31, 2026). This zone is composed of dense networks of thin mineralized veinlets interpreted to represent distributed fractures filled by mineralized fluids within structural interaction damage zones developed around the Bonanza–Golden Gate junctions. 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 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.

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 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.

Based on positive grassroots exploration and drill results in recent years, Goliath now controls 91,518 hectares (226,146 acres), inclusive of 56 kilometers of the Red Linegeologic trend providing for additional discovery potential.

The Golddigger Property is located adjacent to tidewater with a barge route to Prince Rupert (190 km south) and close to existing infrastructure including the town of Kitsault proximal to a permitted mine site on private property.

About Golddigger Property

The Golddigger Property is 100% owned 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 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 shown predictable continuity and good metallurgy with gold recoveries of 92.2% from gravity and flotation at a 327-micrometer crush, including 48.8% 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 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.
