Goldshore Intersects 25.3m of 0.92 g/t Au, Including 3.15m of 5.15 g/t Au from
391.85m, Proving Continuity of Shears Between the Main and Southwest Zones
VANCOUVER, B.C., August 8 , 2025: Goldshore Resources Inc. (TSXV: GSHR / OTCQB:
GSHRF / FWB: 8X00) (“Goldshore” or the “Company”), is pleased to announce its latest assay
results from its recently completed 20,000-meter winter drill program with the final results from
the Golden Gate Zone, a previously undrilled section between the Main and Southwest Zones of
the Moss Gold Project in Northwest Ontario, Canada (the “Moss Gold Project”). A total of 1,380
meters were drilled underneath a saddle in the conceptual open pit with the goal of expanding the
resource beneath the current proposed open pit for a future mineral resource estimate.
Michael Henrichsen, CEO of Goldshore commented, “We are pleased to drill mineralization within
the Golden Gate Zone, the gap between the Southwest and Main zones. The recent drilling has
occurred in a volume that is currently modelled as having few shears extending from the
neighbouring zones and as a result the numerous shears intersected will convert waste in the
current resource mode to mineralized resource. This should enable the Southwest and Main Zone
conceptual open pits to join into a single proposed pit with a less pronounced saddle.”
Highlights
• Four drill holes were completed to infill a data gap beneath a saddle in the conceptual
open pit between the Main and Southwest Zones, an area that was previously untested
and had mineralized shears extended from the neighboring areas. Drilling intersected
medium-grade marginal shears that confirm the continuity of mineralized shears through
this volume with best intercepts of:
o 2.75m of 3.08 g/t Au from 119.25m in MMD-25-184
o 20m of 0.92 g/t Au from 154m in MMD-25-186, including
▪ 4m of 3.01 g/t Au from 159m
o 26.35m of 0.59 g/t Au from 279.85m in MMD-25-187, and
o 25.3m of 0.92 g/t Au from 390m, including
▪ 3.15m of 5.15 g/t Au from 391.85m
• Results from the two remaining shallow holes drilled from ice last winter tested shallow
parts of marginal shears on the southern flank of the Main Zone confirming the extension
of marginal shears including:
o 12m of 0.90 g/t Au from 157m in MMD-25-172, including
▪ 10m of 1.00 g/t Au from 157m
o 8.2m of 0.88 g/t Au from 90.8m in MMD-25-173, including
▪ 2.2m of 2.84 g/t Au from 157m

Technical Overview
Figure 1 shows the location of the drill holes being reported with respect to the completed winter
drill program, while Figure 2 illustrates a cross section through drill holes MMD-25-186 and MMD-
25-187 that demonstrates the potential to extend the mineralized shears zones between the Main
and Southwest Zones to depth. Tables 1 & 2 summarize significant intercepts and drill hole
locations, respectively.

gold-mineralized shears that connects the Main and Southwest Zones
Hole MMD-25-172 was drilled from Snodgrass Lake during the winter ice drilling program testing
the shallow extension of deeper marginal shears on the southern flank of the Main Zone . The
hole collared into an alternati ng andesite and dacitic volcanic package with swarms of meter -
scale weak to moderately sheared, sericite -silica-chlorite altered diorite and porphyritic diorite.
Stronger sheared sections of diorite were mineralized with the presence of pyrite and chalcopyrite
returning a modest intercept of 12m of 0.90 g/t Au from 157m, including 10m of 1.00 g/t Au from
157m up dip and along strike of existing mineralized marginal shears.
Hole MMD-25-173 was drilled from Snodgrass Lake, approximately100m north of MMD-25-172.
The hole collared into alternating dacitic and andesitic volcanics before intersecting the Main Zone
sericite-hematite and epidote-chlorite altered diorite complex at 90m. Local areas of more intense
shearing contained higher-grade mineralization of pyrite and chalcopyrite with intercepts of 8.2m
of 0.88 g/t Au from 90.8m, including 2.2m of 2.84 g/t Au from 90.8m, and 14.0m of 0.35 g/t Au
from 160m. The hole was stopped short of the core shear network as the volume had been
previously drilled.
Holes MMD-25-184, MMD-25-186, and MMD-25-187 were drilled from the same setup on the
western shore of Snodgrass Lake, targeting the gap between the Main and Southwest Zones to
test the continuity of mineraliz ed shears between the two zones. The holes were drilled at an
oblique angle to the primary foliation due to restricted drill sites. This provided the added benefit
of testing a possible NS-structure that offsets the Southwest Zone from the main Moss structure
corridor.

All holes collared in a porphyritic diorite and quickly transitioned into dacite volcanics with swarms
of weak to moderately sheared, sericite -silica-hematite altered diorite and granodiorite dykes
increasing in frequency and alteration and mineralization intensity with depth. At approximately
100m the hole intersected roughly one hundred meters of sheared, sericite-silica-hematite altered
diorite package with pyrite mineralization returning intercepts including 8.3m of 0.63 g/t Au from
105.7m and 2.75m of 3.08 g/t Au from 119.25m in MMD-25-184; 20m of 0.92 g/t Au from 154m,
including 4m of 3.01 g/t Au from 159m in MMD-25-186; and 26.35m of 0.59 g/t Au from 279.85m
in MMD -25-187. The overall lithological and alteration package appear more similar to the
Southwest Zone than the Main Zone with the location of the intercepts suggesting the two zones
are not directly connected. Holes MMD-25-184 and -186, which were drilled at the same
declination but 20° different azimuths, intersected a wide volcanic section characterized by strong
late brecciation and local faulting after which the frequency of diorite intrusions are greatly
reduced. MMD-25-187, which was drilled more steeply beneath MMD-25-186, intersected the
zone of late brittle deformation notably deeper than the up-dip holes after intersecting a second
one hundred and fifty meter wide sericite-chlorite altered diorite complex, returning an intercept
of 25.3m of 0.92 g/t Au from 390m , including 3.15m of 5.15 g/t Au from 391.85m , suggesting a
modest western dip to the structure.
Hole MMD-25-195 was drilled 135m northwest along the shore of Snodgrass Lake at a similar
oblique angle. The hole collared into a dacite volcanic dominate d sequence with swarms of
weakly sheared, sericite-silica-hematite altered diorite, porphyritic diorite, and granodiorite dykes.
The dykes are weakly mineralized with pyrite and narrow low-grade intercepts, such as 5.55m of
0.52 g/t Au from 213.45 and 6.45m of 0.51 g/t Au from 328m. The hole intersected a similar a
wide volcanic section with strong late br ecciation and local faulting after which the diorite
intrusions become notably less frequent.

Analytical and QA/QC Procedures
The HQ diameter drill core (NQ-diameter for holes MMD -25-172 and -173) has been oriented
using ACTIII or equivalent tools and validated in the core shack. All core has been sawed in half
cut just off the core orientation line (bottom of hole) with the right half (looking down hole) of the
core bagged and sent a third-party analytical laboratory. The left half of the core was returned to
core boxes and is stored at Goldshore’s Kashabowie core yard facility.
All samples were sent to ALS Geochemistry in Thunder Bay for preparation and analysis was
performed in the ALS Vancouver analytical facility. ALS is accredited by the Standards Council of
Canada (SCC) for the Accreditation of Mineral Analysis Testing Labor atories and CAN -P-4E
ISO/IEC 17025. Samples were analysed for gold via fire assay with an AA finish (“Au-AA23”) and
48 pathfinder elements via ICP-MS after four-acid digestion (“ME-MS61”). Samples that assayed
over 10 ppm Au were re-run via fire assay with a gravimetric finish (“Au-GRA21”).
In addition to ALS quality assurance / quality control (“ QA/QC”) protocols, Goldshore has
implemented a quality control program for all samples collected through the drilling program. The
quality control program was designed by a qualified and independent third party, with a focus on
the quality of analytical results for gold. Analytical results are received, imported to our secure on-
line database and evaluated to meet our established guidelines to ensure that all sample batches
pass industry best practic e for analytical quality control. Certified reference materials are
considered acceptable if values returned are within three standard deviations of the certified value
reported by the manufacture of the material. In addition to the certified reference material, certified
blank material is included in the sample stream to monitor contamination during sample
preparation. Blank material results are assessed based on the returned gold result being less
than ten times the quoted lower detection limit of the ana lytical method. The results of the on -
going analytical quality control program are evaluated and reported to Goldshore by Orix
Geoscience Inc.
