Goliath Intersects 11.00 g/t Au Over 4.85 Meters, Drilling Maintains 100% Hit Rate,
94% Of Holes Contain Visible Gold, Assays Pending Surebet Discovery,
Golddigger Property, Golden Triangle, B.C.
● 2025 drilling has more than doubled the known extent of the Bonanza Zone from 550 meters to over 1.1 km
across and remains wide open with 100% of the drill holes intersecting substantial quartz -sulphide
mineralization as well as 94% of drill holes containing gold visible to the naked eye (“VG”), assays pending.
● Drilling has been completed in 34 holes (~25,000 meters) within the first month of drilling with 81 holes
remaining (~35,000 meters) on Surebet. With 2 months remaining, the Company is on target to complete the
planned and fully funded ~60,000 meter program with 9 rigs actively drilling.
● Drill hole GD-25-317 intersected excellent gold mineralization in two separate intervals from the Bonanza Zone
and the Surebet Zone that remain open, where 8 occurrences of gold visible to the naked eye were identified
in quartz-stockwork and breccia zones containing moderate amounts of sphalerite, galena and pyrrhotite:
o The Bonanza Zone interval consists of 3.17 g/t Au over 18.73 m eters, including 5.10 g/t Au over 11
meters, including 11 g/t Au over 4.85 meters.
o The Surebet Zone interval consists of 3.64 g/t Au over 9.40 meters, including 6.02 g/t Au over 5.50
meters.
o The reported assays reflect gold only (AuEq value in intervals will be adjusted accordingly once Ag, Cu,
Pb and Zn are received).
2
● Drill hole GD-25-302 intersected substantial gold mineralization in two separate intervals within a 96.50 meter
interval where 6 occurrences of gold visible to the naked eye were identified in an altered andesite unit with
high density quartz-sulphide veining corresponding to the Bonanza Zone that remains open:
o The first interval consists of 2.26 g/t Au over 19.00 meters, including 6.28 g/t Au over 6.00 meters,
including 8.88 g/t Au over 4.00 meters.
o The second interval consists of 1.59 g/t Au over 16.00 meters, including 3.44 g/t Au over 6.00 meters.
o These new intervals extend the footprint of high-grade gold mineralization of the Bonanza Zone to the
south by 150 meters increasing the resource potential of this zone that remains wide open.
o The reported assays reflect gold only (AuEq value in intervals will be adjusted accordingly once Ag, Cu,
Pb and Zn are received).
● Drill hole GD-25-314 intersected 2.25 g/t Au over 4 meters, including 2.82 g/t Au over 3.15 meters part of the
Bonanza Zone.
● Drill hole GD-25-317 is located 180 meters to the northeast and GD-25-302 is located 420 meters to the east of
drill hole GD -24-260, the highest grade gold interval drilled on Surebet to date (see news January 13, 2025) ,
which assayed 34.52 g/t AuEq or 1.11 oz/T AuEq (34.47 g/t Au and 3.96 g/t Ag) over 39.00 meters including
132.93 g/t AuEq or 4.27 oz/T AuEq (132.78 g/t Au and 12.98 g/t Ag) over 10.00 meters, and 166.04 g/t AuEq or
5.34 oz/T AuEq (165.84 g/t Au and 16.07 g/t Ag) over 8.00 meters within an interval composed of altered
andesite with substantial quartz-sulphide veining confirming the additional discovery potential for high-grade
gold mineralization at the Surebet Discovery that remains wide open.

● High-grade gold has now been recovered in three distinct rock packages discovered to date on Surebe t. This
includes the gently dipping gold-rich stacked veins, the gold -rich intermediate to felsic Eocene -aged Reduced
Intrusive Related Gold (RIRG) near vertical dykes, and the newly discovered broad gold-rich zones of calc-silicate
altered breccia, all of which contain substantial amounts of gold visible to the naked eye and remain wide open
for expansion, confirming the presence of the Motherlode magmatic source at depth, a causative intrusion
responsible for the extensive 1.8 km2 high-grade gold system at Surebet.
● The 2025 planned campaign is under way and consists of 60,000 meters (recently increased from 40,000 meters)
of systematic drilling with 9 drill rigs . The campaign aims at expanding the full geometry of the Surebet
discovery laterally and to depth. 100% of the drilling will be focused on the Surebet Discovery, where the
Company has designed a detailed drill plan that will consist of:
o Testing for the Motherlode Magmatic intrusive gold source;
4
o Testing an additional 13 Eocene-aged dykes observed on the surface that have never been drill tested
for RIRG mineralization;
o 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;
o Testing zones where the RIRG Eocene-aged 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
o Expanding the known mineralized veins laterally and to depth where they currently remain open.
Toronto, Ontario – July 28, 2025 – Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) (the “Company”
or “Goliath”) is very pleased to announce positive assay results from drill hole GD-25-317 which assayed 3.17 g/t Au over
18.73 meters, including 5.10 g/t Au over 11 meters, including 11 g/t Au over 4.85 meters within the Bonanza Zone that
remains wide open at Surebet on the 100 % controlled Golddigger Property (the “Property”), Golden Triangle, British
Columbia. An additional gold-rich interval in the same hole consists of 3.64 g/t Au over 9.40 meters, including 6.02 g/t Au
over 5.50 meters part of the Surebet Zone.
Two intervals of high-grade gold mineralization were also intersected in drill hole GD-25-302 that assayed 2.26 g/t Au over
19.00 meters, including 6.28 g/t Au over 6.00 meters, including 8.88 g/t Au over 4.00 meters, and 1.59 g/t Au over 16.00
meters, including 3.44 g/t Au over 6.00 meters. These new intervals extend the footprint of high-grade gold mineralization
of the Bonanza Zone to the south by 150 meters increasing the resource potential of this zone that remains wide open ,
confirming the additional discovery potential for high-grade gold mineralization at the Surebet Discovery.
The Company has completed 2 5,000 meters of drilling (out of 60,000 meters planned and fully funded for 2025), with
100% of the drill holes intersecting substantial quartz -sulphide mineralization as well as 94 % of the holes contain gold
visible to the naked eye. The reported assays reflect gold only (AuEq value in interval will be adjusted accordingly once Ag,
Cu, Pb and Zn are received).
Mr. Roger Rosmus, Founder & CEO of Goliath states: "Receiving exceptional gold only assays of 3.17 g/t Au over 18.73
meters, including 5.10 g/t Au over 11 meters, including 11 g/t Au over 4.85 meters from the first new holes completed in
2025 is a testament to the strong high -grade gold potential at Sur ebet. With 100% of drill holes completed this year
intersecting mineralization, as well as 94% of the holes containing gold visible to the naked eye, we are on track to complete
the most ambitious drill program on Surebet to date with 25,000 meters completed and 35,000 meters to go for a total of
60,000 meters that is fully funded. We are looking forward to releasing additional assay results and updating the gold-
equivalent (AuEq) hole results as they become available.”
Drill hole GD-25-317 intersected 5 occurrences of gold visible to the naked eye (“VG”) hosted in veins that are part of a
quartz-stockwork in sandstone units containing moderate amounts of sulphides such as sphalerite, galena and pyrrhotite.
A 27.68 meter interval with high -density of quartz -sulphide veining from 332.88 meters to 360.56 meters contains 2
occurrences of visible gold at 355.90 meters and 359.47 meters from the Surebet Zone. Another 19.83 meter interval from
441.90 meters to 461.73 meters cont ains multiple quartz-sulphide veins up to 50 cm wide with 2 occurrences of visible
gold at 457.02 meters and 459.66 meters from the Bonanza Zone. Additional VG was identified at 256.90 m . The new
intercept is located 180 meters to the northeast of drill hole GD-24-260, the highest grade gold interval drilled on Surebet
to date, which assayed 34.52 g/t AuEq or 1.11 oz/T AuEq (34.47 g/t Au and 3.96 g/t Ag) over 39.00 meters including 132.93
g/t AuEq or 4.27 oz/T AuEq (132.78 g/t Au and 12.98 g/t Ag) over 10.0 0 meters, and 166.04 g/t AuEq or 5.34 oz/T AuEq
(165.84 g/t Au and 16.07 g/t Ag) over 8.00 meters within an interval composed of altered andesite with substantial quartz-
5
sulphide veining (see news January 13, 2025). Drill hole GD-25-302 intersected 6 occurrences of VG over a 96.50 meter
interval from 89.50 meters to 186.00 meters within an altered andesite unit with high density quartz -sulphide veining
corresponding to the Bonanza Zone that remains open. The new intercept is located 420 meters to the east of drill hole
GD-24-260.

High-grade gold mineralization has been confirmed in three distinct rock packages at the Surebet Discovery, which include:
gently-dipping gold-rich mineralized stacked 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
and remain wide open , w hich strongly indicates the presence of a Motherlode magmatic causative source at depth
responsible for the widespread high-grade gold mineralization at the Surebet Discovery.

2025 re-logging initiative
Recently released results from the re-logging of holes drilled between 2021 – 2024 include a new interval from drill hole
GD-22-64 (see news June 23, 2025) comprising a Reduced Intrusion Related Gold dyke believed to be directly related to
the Motherlode feeder source that contained gold visible to the naked eye and assayed 6.31 g/t AuEq over 14.35 meters
including 11.36 g/t AuEq over 7.85 meters, as well as drill hole GD-24-280 (see news July 7, 2025), which assayed 8.31 g/t
Au over 23.00 meters, including 15.69 g/t Au over 11 meters, including 37.45 g/t Au or 1.20 oz/T over 4 meters hosted in
the calc-silicate altered breccia within the high-grade gold Bonanza Zone.
From the early season re-logging initiative, assays are pending for an additional 6 drill holes containing VG associated with
RIRG dykes, calc-silicate altered breccias and known stacked veins, including:
• GD-24-277 (1 occurrence of VG, hosted in calc-silicate altered andesite breccia);
• GD-22-102 (5 occurrences of VG, hosted in altered andesite);
• GD-24-254 (2 occurrences of VG, hosted in andesite);
• GD-24-267 (1 occurrence of VG hosted in sandstone); and

Surebet Discovery Highlights
32 out of 34 holes (or 94%) drilled thus far in 2025 contain gold visible to the naked eye and a 100% hit rate of
drill holes have intersected substantial quartz-sulphide mineralization.
7
60 out of 64 holes (or 94%) drilled in 2024 contained gold visible to the naked eye up to 11.5 mm (7/16 inches) in
size, all of which returned high-grade gold.
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).
The best hole drilled to date from the third distinct rock package consisting of calc-silicate altered breccia is GD-
24-280 that assayed 8.31 g/t Au over 23.00 meters, including 15.69 g/t Au over 11 meters, including 37.45 g/t Au
or 1.20 oz/T over 4 meters within the Bonanza Zone (see news July 7, 2025).
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 continuously increase the
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 km 2, the equivalent in size to >336 NFL
football fields 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 discovery tremendous untapped discovery
potential to increase tonnage and gold content in the various known rock package. Unt il 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 a total of 92,000 meters with over 400 pierce points on the Golddigger property between 2021
and 2024, which culminated in the updated geologic model used for this year’s drill planning.
The Surebet Discovery has predictable continuity and very 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
8
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 upside 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 Stuhin i rocks and Jurassic age Hazelton rocks used as key markers when exploring for gold -copper-silver
mineralization.
The Surebet discovery has predictable continuity and excellent 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 an excellent 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 th e 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.
