Goldshore Intersects Additional Mineralization Beneath the Conceptual Open Pit
at the Southwest Zone with 22m of 1.30 g/t Au
VANCOUVER, B.C., July 25, 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
Southwest Zone of the Moss Gold Project in Northwest Ontario, Canada (the “ Moss Gold
Project”). A total of 5,000 meters were drilled targeting the area underneath the conceptual open
pit at the Southwest Zone of the Moss deposit 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 with the results of the
program underneath the Southwest pit demonstrating good widths at above average resource
grades supported by several parallel marginal shears . The new drilling in conjunction with
previous intercepts located beneath the conceptual open pit at the Southwest Zone gives us
confidence in adding significant additional ounces in a future resource estimate based on the
success of the recently completed winter drill program.”
The latest drilling at the Southwest Zone focused on infilling the sparsely drilled area between the
current MRE conceptual open pit and the high -grade intercepts encountered up to 175m further
below, including previously released mineralized intercepts of 39.75m of 1.18 g/t Au from
440.25m, including 14.60m of 2.65 g/t Au from 462.2m in MMD-22-023 (August 10, 2022), 23.0m
of 1.92 g/t Au from 514.0m, including 1.55m of 22.9 g/t Au from 514.0m in MMD-22-25 (June 6,
2022), 20.55m of 2.58 g/t Au from 458.15m, including 14.7m of 3.52 g/t Au in MMD -24-139
(February 20, 2025) , and 15.0m of 1.68 g/t Au from 456m, including 3.0m of 3.19 g/t Au from
458.0m in MMD-25-140 (March 20, 2025).
Highlights
Seven drill holes were completed to infill a data gap between shallow and deep intercepts at the
Southwest Zone and a consequent gap in the resource model that is treated as waste in the pit
optimization process.
• Three holes intersected high-grade core shears with best intercepts of:
o 12.3m of 1.11 g/t Au from 556m in MMD-25-183, including
▪ 6.3m of 1.94 g/t Au from 562m
o 10.0m of 2.76 g/t Au from 314m in MMD-25-185, including
▪ 5.0m of 5.06 g/t Au from 314m
o 22.0m of 1.30g/t Au from 533m in MMD-25-191, including
▪ 3.9m of 3.48 g/t Au from 541.1m

• All seven drill holes intersected multiple parallel shear zones that confirmed the continuity
of the shear zone system both laterally and at depth and demonstrate the potential to add
to ounces to the existing mineral resource estimate. Highlights from these peripheral shear
zones, which include narrow zones of +1 g/t Au, are presented in Table 1.

Technical Overview
Figure 1 shows the location of the drill holes being reported with respect to the planned winter
drill program , while Figure 2 illustrates a cross section through drill hole MMD-25-185 that
demonstrates the potential to extend the mineralized shears zones of the Southwest zone to
depth. Tables 2 & 3 summarize significant intercepts and drill hole locations , respectively. All
seven drill holes were drilled to infill a data gap between shallow and deep intercepts at the
Southwest Zone and a consequent gap in the resource model that is treated as waste in the pit
optimization process.

Holes MMD-25-182, MMD -25-190, and MMD-25-191 were drilled on the eastern side of the
Southwest Zone and collared into a generally undeformed porphyritic diorite before transitioning
into an alternating sequence of sericite -chlorite altered brecciated dacitic volcanics and weakly
mineralized hematite-sericite-silica altered diorite dykes. All three holes intersected the primary
diorite complex of the Southwest Zone towards the end of the holes encountering sheared
sericite-silica-hematite altered diorites and granodiorites with 2-3% pyrite-chalcopyrite. MMD-25-
182 was terminated early into the diorite complex, as it had already intersected its primary target.
The mineralized diorites returned wide intercepts of moderate to high grades, including 18.2m of
0.46 g/t Au from 381.8m in MMD-25-182, 10.0m of 0.97 g/t Au from 260.0m, including 2.0m of
2.54 g/t Au from 262.0m, and 24.6m of 0.50 g/t Au from 342.4m in MMD-25-190, and 20.0m of
0.54 g/t Au from 241.0m and 22.0m of 1.30g/t Au from 533m including 3.9m of 3.48 g/t Au from
541.1m in MMD-25-191.
Holes MMD-25-183, MMD-25-185, MMD-25-188, and MMD-25-189 were drilled on the western
side of the Southwest Zone and all collared into the northern dacite volcanic package consisting
of silica -sericite altered brecciated dacite volcanics with localized meter scaled diorite dykes
increasing with frequency at depth. All holes transitioned into the primary Southwest Zone diorite
complex of sericite -silica-hematite altered dior ites and granodiorites with locally moderately to
strongly shears bearing 3-5% pyrite-chalcopyrite. These sheared sections returned low to high
grade mineralized intercepts such as 17.0m of 0.48 g/t Au from 371.0m and 12.3m of 1.11 g/t Au
from 556m, including 6.3m of 1.94 g/t Au from 562m, in MMD-25-183, 17.0m of 0.67g/t Au from
180m, including 3.0m of 1.67 g/t Au from 183m, 11.6m of 1.06 g/t Au from 286m, and 10.0m of
2.76 g/t Au from 314m, including 5.0m of 5.06 g/t Au from 314m, in MMD-25-185, 17.65m of 0.70
g/t Au from 372.35m and 18.25m of 0.62 g/t Au from 460.0m in MMD-25-188, and 14.3m of 0.68
g/t Au from 310.7m, including 4.25m of 1.67 g/t Au from 314.0m, 22.0m of 0.55 g/t Au from
474.0m, including 3.0m of 1.68 g/t Au from 474.0m, in MMD-25-189.

Analytical and QA/QC Procedures
The HQ diameter drill core 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 bagge d 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 practice 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 analytical method. The results of the on-
going analytical quality control program are evaluated and reported to Goldshore by Orix
Geoscience Inc.
