Surebet Definitively Proven To Be Part of a Large-Scale Tier-1 Reduced

Intrusion Related Gold System With Tremendous Upside Remaining,

Golden Triangle, B.C.

Highlights Of The Geological Study Completed By The Colorado School Of Mines:

● A detailed geological study was recently completed by the Colorado School of Mines utilizing

a compilation of drill holes and geological data. Conclusions of the geological study confirms a

new interpretation of the ore forming process of high-grade gold mineralization at Surebet and

confirms common causative Reduced Intrusion Related Gold (RIRG) source with tremendous

untapped discovery potential.

● High-grade gold mineralization at Surebet occurs in two different settings , both containing

visible gold in remarkably high percentages of the drill hole intersections. Of particular note is

that the visible gold is fine to coarse grained, and includes up to abundant visible gold, with an

increase of coarseness and abundance in vertical distribution. Which is consistent with the

assessment that the system is getting richer as it is drilled deeper, and both styles of high-grade

gold mineralization are open in all directions:

o Shear hosted veins up to 3 9 meters wide where gold occurs as native or alloys with

bismuth and tellurium within quartz-sulphide veins hosted in sedimentary and volcanic

rock units.

o Multiple millimeter to centimeter wide quartz veinlets where gold occurs with

bismuth, tellurium, and molybdenite within felsic to intermediate dykes.

● 12 vertically stacked gold mineralized shear-hosted veins within the sedimentary and volcanic

rock units have been confirmed through drilling and modelling at Surebet with grades up to

34.52 g/t AuEq (34.47 Au and 3.96 Ag) over 39.00 meters. These stacked layers are up to 3 9

meters wide within a 1.8 km 2 area that remains open showing the excellent additional blue -

sky potential.

● Multiple high -grade gold intervals from reduced intrusion related porphyritic felsic to

intermediate feeder dykes assayed up to 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over

10.00 meters. The gold mineralized feeder dykes are up to 25 meters wide and exposed along

strike at surface for up to 1,500 meters and remain open, strongly indicating close proximity

to a gold-rich Motherlode RIRG source (previously announced March 13, 2025).

● Dating of volcanic-hosted gold mineralization related to the shear hosted veins resulted in an

age of 50.7 ± 1.0 Ma. This result overlaps with the U -Pb zircon age of 52.0 ± 1.5 Ma obtained

for the mineralized felsic to intermediate dykes. The overlap in mineralization age for both

shear-hosted gold-rich veins and gold-bearing dykes suggests a common causative intrusion as

the source of mineralization.

● Eocene age (56 to 34 Ma) mineralization has been neglected in the southern part of the Golden

Triangle, where most of the known deposits are thought to be Jurassic age (201 to 145 Ma).

The discovery of abundant Eocene age mineralization at Surebet shows the tremendous

untapped discovery potential that is left on the Golddigger property.

● Recent research by the Colorado School of Mines has indicated the presence of two stages of

gold mineralization in the gold-rich veins at Surebet within the shear hosted veins and the felsic

to intermediate dykes:

o The first stage of gold mineralization resulted in the deposition of native bismuth,

bismuth tellurides, and the gold -bismuth mineral maldonite and is associated with

calc-silicate alteration including actinolite. This early mineralization occurs primarily in

quartz veins crosscutting gold-bearing dykes and the volcanic rocks.

o The later assemblage of gold mineralization crosscuts the early stage and is associated

with chlorite alteration. This late stage of gold makes up most gold observed in the

shear-hosted veins.

● The paragenetic relationships of minerals are consistent with alteration occurring from a

cooling hydrothermal system in both the shear and dyke hosted veins. This provides further

evidence that the dykes and shear-hosted gold veins at Surebet may be related to a causative

intrusion at depth that may have acted as the heat source for the hydrothermal system and

likely contributed significant free gold.

● At Surebet, multiple gold-bismuth-tellurium grains have textural characteristics which indicate

that they were entrapped as melt droplets within the host quartz. Fluid inclusions associated

with these melt droplets provide evidence for the contemporaneous occurrence of phase

separation of the CO 2-rich magmatic-hydrothermal fluids, a process not previously described

in the scientific literature.

● Confirmation of high gold grades over broad intervals in the recently discovered RIRG system

characterized by considerable amounts of visible gold, bismuth, bismuth tellurides and

molybdenum mineralization in the felsic to intermediate porphyritic dykes on Surebet

materially increases the size potential of the various gold zones at the Surebet discovery.

● During only 15 months of boots on the ground, strong gold mineralization has been confirmed

in 100% of 243 widespread drill holes containing >300 intercepts to date within a 1.8 km2 area.

The multiple stacked gold veins and widespread gold -rich reduced intrusion feeder dykes,

confirms the continuity of the widths and grades at Surebet demonstrating this world -class

gold-rich system has tremendous additional untapped expansion potential remaining.

Toronto, Ontario – April 24, 2025 – Goliath Resources Limited (TSX -V: GOT) (OTCQB: GOTRF) (FSE: B4IF)

(the “Company” or “Goliath”) is pleased to report the results of the geological study completed by the

Colorado School of Mines which confirms new ore forming process of high-grade gold mineralization and

common causative Reduced Intrusion Related Gold (RIRG) source with tremendous untapped discovery

potential at Surebet on its 100% controlled Golddigger Property (the “Property”), Golden Triangle, B.C.

Two stages of gold mineralization clearly associated with a RIRG system as well as overlap in mineralization

and alteration ages for shear hosted veins and dykes, and paragenetic relationships of minerals consistent

with alteration occurring from a cooling hydrothermal system, strongly indicate a common RIRG feeder

source at Surebet.

Roger Rosmus, Founder and CEO of Goliath Resources, states: “Since our initial discovery at Surebet of an

extensive outcropping zone of gold mineralization, followed by drilling below to make a discovery of a series

of stacked gently dipping high-grade gold veins, and then a series of vertical dykes through the stacked veins,

our understanding of the overall system has been aided by the great work by the team at the Colorado School

of Mines. The 2024 drilling season was our best ever, highlighted by visible gold in 92% of the holes drilled,

including fine-grained to coarse-grained and abundant visible gold that got better as we drilled deeper into

the discovery. Another important milestone in 2024 was our success drilling into a series of near vertical dykes,

also with visible gold and high-grade gold assays, that come up through the gently dipping stacked veins. All

of our drilling and geological work enabled us to provide a remarkable amount of material and data for the

team at the Colorado School of Mines to enhance the modeling, interpretation and thesis of what has caused

the high-grade gold mineralization we have drilled into with great success so far. In a general sense, we have

determined that we have a series of gently dipping high-grade veins with vertical RIRG zones (also with high-

grade gold) through the veins. Which have enriched the veins, and there is a likelihood that they are all coming

from a common source. When you consider how widespread the high-grade gold mineralization is in the veins

and RIRG zones, the source is potentially extremely large. The more drilling and scientific studies we do at the

Surebet discovery, the better it gets, and we are still high in the system that is open in all directions, and we

are delighted with the prospect with what can be found as we continue to laterally and drill deeper for the

source of the high-grade gold system.”

Gold mineralization at Surebet occurs in two different setting: 1) shear hosted veins up to 3 9 meters wide

where gold occurs as native or alloys with bismuth and tellurium within quartz -sulphide veins hosted in

sedimentary and volcanic rock units and 2) multiple millimeter to centimeter wide quartz veinlets where gold

occurs with bismuth, tellurium, and molybdenite within felsic to intermediate dykes. Direct dating of

volcanic-hosted sulphide mineralization related to the shear hosted veins resulted in an age of 50.7 ± 1.0 Ma.

This result overlaps with the U -Pb zircon age of 52.0 ± 1.5 Ma obtained for the mineralized felsic to

intermediate dykes. The overlap in mineralization age for both shear -hosted veins and gold -bearing dykes

suggests a common causative intrusi on as the source of mineralization observed at Surebet. Petrographic

and fluid inclusion analysis carried out on samples from the mineralized shear-hosted veins in an earlier phase

of the project indicated that the fluid responsible for the gold mineralization at Surebet is of magmatic origin

(previously announced February 2, 2023) further corroborating the hypothesis of a common magmatic

source for the mineralization. Eocene age (56 to 34 Ma) mineralization has been neglected in the southern

part of the Golden Triangle, where most of the known deposits are thought to be Jurassic age (201 to 145

Ma). The discovery of abundant Eocene age mineralization at Surebet shows the tremendous untapped

discovery potential that is left on the Golddigger property and surrounding areas. Structures and lithologies

younger than Jurassic which have been historically overlooked now provide excellent targets for styles of

gold mineralization which may have been overlooked.

New research has indicated the presence of two stages of gold mineralization in the gold -bearing veins at

Surebet within the shear - hosted veins and the felsic to intermediate dykes. The first stage of gold

mineralization resulted in the deposition of native bismuth, bismuth tellurides, and the gold-bismuth mineral

maldonite. This stage of gold mineralization is associated with calc-silicate alteration including actinolite. This

early mineralization occurs primarily in quartz veins crosscutting gold -bearing dykes and the volcanic rocks.

Gold-bismuth-tellurium grains from this stage are commonly observed as inclusions along healed

microfractures in quartz. The later assemblage of gold mineralization crosscuts the early stage and is

associated with chlorite alteration. This late stage of gold makes up most gold observed in the shear-hosted

veins at Surebet. Samples taken from an interval i n hole GD-24-260 that assayed 34.52 g/t AuEq (34.47 Au

and 3.96 Ag) over 39.00 meters ( previously announced January 13, 2025) are found to have significant

quantities of both the early and late gold stages, possibly explaining the high -grade observed. This overlap

between dyke-typical and shear-hosted vein-typical mineralization further suggests both styles of gold are

expressions of the same system.

The paragenetic relationships of minerals determined through petrographic work are consistent with

alteration occurring from a cooling hydrothermal system in both the shear and dyke -hosted veins. This

finding provides further evidence that the dykes at Surebet may be related to a causative intrusion at depth

that may have acted as the heat source for the hydrothermal system and likely contributed significant metals.

Additionally, the gold-bismuth-tellurium grains have textural characteristics which indicate that they were

entrapped as melt droplets within the host quartz. Fluid inclusions associated with these melt droplets

provide evidence for the contemporaneous occurrence of phase s eparation of the CO 2-rich magmatic -

hydrothermal fluids, a process not previously described in the scientific literature. Further research at the

Colorado School of Mines will be focused on understanding this new mechanism for ore formation and its

role in the formation of high-grade gold mineralization at Surebet.

During only 15 months of boots on the ground, strong gold mineralization has been confirmed with assays in

100% of 243 widespread drill holes containing >300 intercepts to date within a 1.8 km 2 area with 20 holes

contain intervals over 100 gram*meter Au (> 3 ounces*meter Au). Confirmation of multiple stacked gold

veins and widespread gold -rich reduced intrusion feeder dykes, confirms the continuity of the widths and

grades at Surebet demonstrati ng this world -class gold system has tremendous additional untapped

expansion potential remaining.

Golddigger Property

The Golddigger Property is 100% controlled and covers an area of 91,518 hectares in the world class

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 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 Li ne 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 exceptional continuity and excellent metallurgy with gold recoveries of 92.2% with

48.8% of it as free gold from gravity alone at a 327 -micrometer crush (no cyanide required to recover the

gold). The metallurgy completed to date shows no deleterious elements are present such as mercury or

arsenic.

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 loc ated on the west coast and houses

an international container seaport also with direct access to railway and an airport.

The reader is cautioned that grab samples are spot samples which are typically, but not exclusively,

constrained to mineralization. Grab samples are selective in nature and collected to determine the presence

or absence of mineralization and are not intended to be representative of the material sampled.

Oriented HQ-diameter or NQ-diameter diamond drill core from the drill campaign is placed in core boxes by

the drill crew contracted by the Company. Core boxes are transported by helicopter to the staging area and

then transported by truck to the core shack . The core is then re -orientated, meterage blocks are checked,

meter marks are labelled, Recovery and RQD measurements taken, and primary bedding and secondary

structural features including veins, dykes, cleavage, and shears are noted and measured. The cor e is then

described and transcribed in MX Deposit TM. Drill holes were planned using Leapfrog Geo TM and QGIS TM

software and data from the 2017 -2022 exploration campaigns. Drill core containing quartz breccia,

stockwork, veining and/or sulphide(s), or notable alteration are sampled in lengths of 0.5 to 1.5 meters. Core

samples are cut lengthwise in half, one-half remains in the box and the other half is inserted in a clean plastic

bag with a sample tag. Standards, blanks and duplicates were added in the sample stream at a rate of 10%.

Grab, channels, chip and talus samples were collected by foot with helicopter assistance. Prospective areas

included, but were not limited to, proximity to MINFile locations, placer creek occurrences, regional soil

anomalies, and potential gossans based on high-resolution satellite imagery. The rock grab and chip samples

were extracted using a rock hammer, or hammer and chisel to expose fresh surfaces and to liberate a sample

of anywhere between 0.5 to 5.0 kilograms. All sample sites were flagged with biodegradable flagging tape

and marked with the sample number. All sample sites were recorded using hand-held GPS units (accuracy 3-
