Goldshore Intersects 53m of 2.03 g/t Au from 160m in the Main Zone
VANCOUVER, B.C., August 12 , 2025: Goldshore Resources Inc. (TSXV: GSHR / OTCQB:
GSHRF / FWB: 8X00) (“Goldshore” or the “Company”), is pleased to announce the last batch
of assay results from the Company’s recently completed 20,000-meter winter drill program (Figure
1) with the final results from six shallow holes drilled to confirm results from historical underground
drill holes at the Main Zone of the Moss Gold Project in Northwest Ontario, Canada (the “ Moss
Gold Project”). The recently completed drill holes are part of a program to replace historical drill
holes for which collar surveys, downhole surveys and/or assay results cannot be confirmed to
support a future Measured and Indicated mineral resource estimate.
Michael Henrichsen, CEO of Goldshore commented, “We are pleased to confirm the quality of
mineralization within the Moss Main Zone. The winter program has clearly demonstrated the
emerging nature of the Moss deposit through significant growth under the conceptual open pit at
the Southwest Zone, bringing mineralized shear zones up to surface from approximately 100 –
150 meters depth at the QES zone, the discovery of high-grade near surface mineralization at the
Superion Zone, and now confirming high-grade mineralization at the Moss Main Zone associated
with a historical underground exploration drift at the Main Zone. We look forward to bringing the
results of the winter program into an updated mineral resource estimate in Q4 of this year in
conjunction with the PEA, both being completed by G Mining Services.”

Highlights
• Six short drill holes were completed to replace historical underground drill holes within the
shear corridor. These drill holes successfully confirmed the presence of several close-
spaced, anastomosing, high- grade gold-mineralized shear zones modelled in the Main
Zone, with best intercepts of:
o 27.3m of 0.88 g/t Au from 21.7m in MMD-25-192, including
8.55m of 1.86 g/t Au from 37.25m, and

7.0m of 2.18 g/t Au from 124m, and

2.0m of 8.92 g/t Au from 180m
o 62.5m of 1.16 g/t Au from 11m in MMD-25-194
o 70.0m of 1.11 g/t Au from 8m in MMD-25-196, including

The six shallow holes were designed to confirm the continuity and higher grades indicated by the
historical drilling from the underground exploration drift. However, since the drift is no longer
accessible, the precise location of these historical holes could not be confirmed. Additionally,
these historical holes have limited downhole survey s, which create greater uncertainty in the
positioning of assay composites . Minor spatial irregularities with high grade mineralized shears
were noted and are believed to be caused by the above-mentioned limited survey control. Another
factor is that the underground holes were drilled using BQ rods, whereas all current drilling is HQ
diameter.
Hole MMD-25-192 and MMD-25-193 were drilled to confirm the results of the historical
underground drilling off the eastern side of the exploration drift. The historical holes and the
eastern zone were drilled longer than the others to test a second group of high-grade shears. The
holes collared into a moderate to strongly sheared, sericite-silica-chlorite altered diorite complex
with broad pyrite-chalcopyrite mineralization that increases with the intensity of shearing. Intense
shearing corresponds to higher grade intercepts, including 8.55m of 1.86 g/t Au from 37.25m,
5.0m of 3.26 g/t Au from 139m, 4.35m of 5.34 g/t Au from 172.85m, and 19.6m of 3.25 g/t Au from
183.0m in MMD-25-192; and 10.5m of 4.17 g/t Au from 55.5m, 7.0m of 2.18 g/t Au from 124.0m,
and 2.0m of 8.92 g/t Au from 180.0m in MMD-25-193. These shears bulk out to broader intercepts
of 39.0m of 1.09 g/t Au fr om 79.0m and 53.0m of 2.03 g/t Au from 160 .0m in MMD-25-192; and
29.4m of 1.73 g/t Au from 37.0m, 19.0m of 1.09 g/t Au from 124.0m and 30.0m of 1.14 g/t Au from
175.0m in MMD-25-193. The shearing intensity and mineralization both weaken towards the end
of the holes where they exit the core shear system.
Holes MMD-25-194, MMD-25-196, MMD-25-197, and MMD-25-198 were drilled to confirm the
historical underground drilling results from the central and western sides of the exploration drift.
The holes collared into the same moderate to strongly sheared, sericite -silica-hematite altered
diorite complex which continued throughout each hole. The strongly sheared section contained
increased pyrite-chalcopyrite mineralization with higher grade intercepts including 18.05m of 1.89
g/t from 19.95m in MMD-25-194; 19.0m of 1.53 g/t Au from 32.0m and 10.0m of 2.53 from 113.0m
in MMD-25-196; 12.0m of 2.12 g/t Au from 7.0m, 4.0m of 5.98 g/t Au from 57.0m, and 14.05m of
3.47 g/t Au from 80.95m in MMD-25-197; and 7.0m of 2.79 g/t Au from 83.0m in MMD-25-
198.These shears bulk out to broader intercepts with 62.5m of 1.16 g/t Au from 11.0m in MMD -
25-194; 70.0m of 1.11 g/t Au from 8.0m in MMD -25-196; 45.0m of 1.10 g/t Au from 5.0m and
30.0m of 2.00 g/t Au from 67.0m in MMD -24-197; and 81.0m of 0.68 g/t Au from 9.0m in MMD -
25-198. The holes were stopped within mineralization after they had passed the extent of the
underground drilling.

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 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 analytical method. The results of the on -
going analytical quality control program are evaluated and reported to Goldshore by Orix
Geoscience Inc.
