Drills Are Turning At Goliath Resources Fully Funded 50,000 Meter Expansion
Drill Program On High-Grade Gold Surebet Discovery, Golden Triangle, B.C.
✓ Drilling has commenced on the high-grade gold Surebet Discovery with 2 drills on site and 5 additional drills arriving
shortly for a total of 7 drill rigs to carry out the fully funded 2026 planned drill program.
✓ This year’s plan is targeting 50,000 meters of systematic drilling designed to expand the known mineralization
laterally and to depth in order to test the extent of the Surebet discovery as well as the potential location of the
Motherlode Feeder Source. The system remains open in multiple directions.
✓ Expansion drilling will focus on extending the footprint of the Bonanza Zone and Golden Gate Zone to the East,
Northeast and Southwest as well as expanding the Surebet Zone to the West and testing other gold -rich
mineralized lodes/veins that remain open, based on the surface expression of the zones observed in outcrop:
o The Bonanza Zone can be traced on the surface for approximately 3 kilometres along the north slope, with
potential extension of 1.3 kilometres to the Northeast and 600 metres to the Southwest; see image below.
o The Surebet Zone can be traced on surface for 1.1 kilometres along the north slope and 1 km along the
south slope; see images below.

✓ Additional drilling will be allocated to test a magnetic anomaly in the southwestern part of the system which is
spatially associated with lithological and structural datasets and strongly indicates the presence of a Motherlode
causative magmatic intrusion gold feeder source; see image below.

✓ A drill core re-logging program is underway focused on better delineating the gold-rich shear zones and veins based
on the improved understanding of the geometry and grade distribution as a result of the updated geological model
of the Surebet system that remains open.
Toronto, Ontario – June 17, 2026 – Goliath Resources Limited (TSX-V: GOT) (OTCQX: GOTRF) (FSE: B4IF) (the “Company” or
“Goliath”) is pleased to report that drilling has commenced at the high-grade gold Surebet discovery on its 100% owned
Golddigger Property (the “Property”), Golden Triangle, British Columbia. The fully funded drill program will include
approximately 50,000 meters of systematic drilling designed to expand the known mineralization laterally and to depth (all
mineralized lodes/veins remain open for expansion and new discoveries), as well as test for the Motherlode Magmatic Gold
Feeder Source.
Expansion drilling will focus on extending the footprint of the Bonanza Zone and Golden Gate Zone to the East, Northeast and
Southwest, as well as expanding the Surebet Zone to the West and testing other gold-rich mineralized lodes/veins that remain
open. Additional drilling will be allocated to testing a number of lithological-structural features linked to magnetic anomalies
strongly indicating the presence of a Motherlode causative magmatic intrusion gold feeder source.
Every drill hole completed to date (2021 – 2025) within the 1.8 km 2 Surebet discovery has successfully intersected gold
mineralization. These results confirm predictable continuity, grade, and width across 5 gold-rich zones comprising 46 distinct
stacked lodes/veins, all of which remain open for expansion. Visible gold to the naked eye (VG-NE) is found in 92% of the drill
holes to date at the Surebet Discovery, in three distinct rock packages, with the VG -NE widespread in the majority of the
known lodes/veins. The remarkable continuity, widths and grades encountered across multiple lodes /veins underscore the
significance of this large gold system which has strong potential to become one of the most significant gold discoveries in
British Columbia’s Golden Triangle in many years. Success to date has effectively vectored toward several open targe ts,
providing a strong foundation for further expansion in the 2026 drilling campaign.
Building on the updated geological model of the Surebet system, a drill core re -logging program is currently underway. This
re-logging program focuses on better defining the gold -rich shear zones and veins by applying the improved understanding
of the system's geometry and grade distribution based on the updated 3D model.
Mr. Roger Rosmus, Founder & CEO of Goliath states: “Goliath is fortunate to have an elite team of geologists, drillers and
support staff that have done a remarkable job every drilling season. They have pulled off what few teams are able to do in a
year of drilling over a few months. To date, we have found a series of stacked lodes/veins that are gently dipping, similar to
the Pogo Mine in Alaska which was found when gold was much lower than its current price. Of particular note about Surebet
is the 100% hit rate for drill holes intersecting gold mineralization, with 92% intersecting VG-NE. These facts alone make
Surebet a unique high-grade gold system. Especially considering that the VG-NE is widespread over a large area in three
distinct rock packages putting it in a class that only a few discoveries worldwide can boast of having found in their drill holes.
It is still somewhat surprising that after 156,000 meters drilled to date, that we have still not reached the limits of the
system. Considering the geochemical signatures as we drill further down the mountain toward the valley floor, and that the
VG-NE is getting more coarse and abundant, they are great tools for vectoring to the source and also indicate we are likely
still high in the system. This season, we have a few key goals, one is to keep following the stacked veins laterally to expand
on the Surebet lodes/veins and the Bonanza lodes/veins, plus testing a possible source that has a large concurrent
geophysical anomaly. Each season the Surebet high-grade Gold Discovery gets bigger and delivers pleasant surprises, we are
delighted to get the 2026 drilling season underway.”
Surebet Discovery Highlights
✓ 100% of the drill holes completed to date within the 1.8 km2 Surebet discovery have intersected gold mineralization
clearly demonstrating remarkable continuity, grades, and widths with of over 1,500 drill hole pierce points.

✓ The updated geological model incorporating all currently available data identifies 5 primary mineralized gold-rich
zones: Bonanza, Surebet, Golden Gate, Whopper, and Eldorado. Collectively these zones comprise 46 gold -rich
stacked lodes/veins and associated vertical Eocene-aged dykes.
Zone
Number of
lodes/veins Dimensions Key Intercept Status
Bonanza 5 1.8 km x 1.3 km x 19 m 8.35 g/t AuEq over 23 m Remains Open
Surebet 9 1.2 km x 1.0 km x 19 m 21.08 g/t AuEq over 23 m Remains Open
Golden Gate 18 1.3 km x 1.0 km x 14 m 34.52 g/t AuEq over 39 m Remains Open
Whopper 12 1.0 km x 1.0 km x 6 m 32.67 g/t AuEq over 4 m Remains Open
Eldorado 2 1.0 km x 900 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
✓ The gold-rich Eocene-aged dykes extend for up to 1.4 km N-S and a vertical relief of up to 890 meters with widths up
to 25 meters and intercepts up to 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10.00 meters (drill hole GD-22-
58) and remain open for expansion.
✓ 355 out of 386 drill holes representing 92% of holes drilled to date (2021 – 2025) at Surebet contain Visible Gold to
The Naked Eye (VG-NE); see map below.

✓ High-grade gold has been identified in three distinct rock packages identified to date at the Surebet Discovery. This
includes the gold -rich stacked quartz -sulphide breccias and stockwork veins hosted in the sedimentary units; the
precious and base metals bearing veins hosted in the volcanic units; and the gold-rich 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.
✓ Metallurgical testing conducted on a composite core sample resulted in remarkable recoveries through a combination
of simple gravity and flotation of 92.2% for Au, 86.5% for Ag, 94.2% for Pb and 96.9% for Zn. Recoveries through
simple and cost-effective gravity alone 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 metallurgy completed to date shows a benign rock
composition without deleterious elements (see news release March 1, 2023).
✓ The remarkable continuity, widths and grades demonstrated by >156,000 meters of drilling in multiple lodes shows
this extensive 1.8 km2 gold system continues to demonstrate strong potential to become one of the most significant
gold discoveries in British Columbia’s Golden Triangle in many years.
✓ 92% of the holes (355 out of 386) drilled to date at Surebet contain VG-NE (see VG-NE heat map above) and 100% of
holes drilled to date at the Surebet Discovery have intersected substantial 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,

October 27, 2025, September 22, 2025, September 8, 2025, August 26, 2025, and July 28, 2025.
✓ 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
6
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 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.
✓ 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 in three
distinct rock packages. This gives the Surebet untapped discovery potential to increase tonnage and gold content in
the various known rock packages. Until this study, researchers and explorers in the Golden Triangle had not
recognized the high -grade gold d iscovery 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 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 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.

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.
QA/QC Protocol
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 core is then described and transcribed in MX DepositTM. Drill holes were planned using Leapfrog
GeoTM and QGISTM software and data from the 2017 -2025 exploration campaigns. Drill core containing quartz breccia,
stockwork, veining and/or sulphide(s), or notable alteration is selectively sampled in lengths of 0.5 to 1.5 meters. Samples are
selected from continuous intervals of mineralization and/or other relevant geological features, including shoulder samples
that extend for 3 meters into adjacent unmineralized and/or unaltered country rock. Along barren core intervals devoid of
mineralization or significant geological features, one 1 meter sample is collected every ten met ers. 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. The
bagged samples are then weighed and secured with a zip tie. Certified reference materials (CRMs), blanks and duplicates are
added in the sample stream at a rate of 10%. To ensure analytical anonymity, CRM identification labels are removed prior to
submission to the laboratory. Additional out -of-sequence blanks are introduced immediately following core samples that
contain visible gold to the naked eye (VG-NE) or visibly high-grade sulphide mineralization.
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 samples weighing anywhere between 0.5 and 5.0 kilograms. All sample
sites were flagged with biodegradable flagging tape and marked with the sample number. All sample site locations were
recorded using handheld GPS units (accuracy 3 -10 meters) and sample ID, easting, northing, elevation, type of sample
(outcrop, subcrop, float, talus, chip, grab, etc.) and a description of the rock were recorded on all -weather paper. Samples
are then inserted in a clean plastic bag with a sample tag for transport and shipping to the geochemistry lab. QA/QC samples
including blanks, certified reference materials, a nd duplicate samples are inserted regularly into the sample sequence at a
rate of 10%.
All samples are transported in rice bags sealed with numbered security tags. The rice bags are transported from the core
shacks to the MSALABS facilities in Terrace, BC. MSALABS is certified with both AC89 -IAS and ISO/IEC Standard 17025:2017.
The core samples undergo preparation via drying, crushing to ~70% of the material passing a 2 mm sieve and riffle splitting.
The sample splits are weighed and transferred into plastic jars, each containing between 300 g and 500 g of crushed sample
material. A 250 g split is pulverized to ensure at least 85% of the material passes through a 75 µm sieve. The crushed samples
are transported to the MSALABS PhotonAssayTM facility in Prince George, where gold concentrations are quantified via
