Goldshore Resources Inc. (TSX-V: GSHR) (OTCQB: GSHRF) (FWB: 8X00) is pleased to announce its latest assay results from its completed 20,000-meter drill program and the results of the follow-up drilling on the recently discovered, near-surface, mineralized zone at the Superion target, north of the QES zone at the Moss Gold Project in Northwest Ontario, Canada.

Michael Henrichsen, CEO of Goldshore commented, “We are pleased to see Superion emerge as a high-grade zone, near surface, that sits on the northern margin of the conceptual open pit.  With multiple intercepts into the mineralized structure, we have gained valuable knowledge of its orientation and believe we will be able to expand the zone significantly along strike. The Company has completed the 20,000-meter drill program with an additional 18 drill holes to be reported over the coming weeks.”

Highlights:

• Results from a follow-up fence of holes surrounding the MQD-25-148 intercept (17.6m of 3.03 g/t Au from 76.4m) as reported in the Company’s news release dated on March 3, 2025, have increased the strike length of the new zone to over 100 meters, which remains open in all directions. Best intercepts include:
  • 9.45m of 6.02 g/t Au from 186.0m in MQD-25-175, including
    • 2.45m of 22.2 g/t Au from 193.0m
  • 13.0m of 2.30 g/t Au from 117.0m in MQD-25-176, including
    • 3.0m of 9.00 g/t Au from 124.0m, and
  • 10.0m of 1.17 g/t Au from 144.0m including
    • 4.0m of 2.67 g/t Au from 149.0m
  • 3.5m of 2.72 g/t Au from 41.4m in MQD-25-177, including
    • 0.4m of 9.67 g/t Au from 43.0m, and
  • 3.0m of 3.54 g/t Au from 242.0m, including
    • 1.0m of 7.28 g/t Au from 242.0m

• Exploratory holes drilled across the largely untested area east of Superion intersected numerous mineralized shears similar in nature to marginal shears surrounding the Moss deposit, including:
  • 0.3m of 5.37 g/t Au from 224.2m in MQD-25-146, and
  • 2.25m of 1.17 g/t Au from 248.75m
  • 4.06m of 1.08 g/t Au from 140.65m in MQD-25-149

Drill results reported herein are from the Superion drill program, targeting a significant and largely untested area of swampy terrain northeast of the Moss deposit. Drilling aimed to identify new zones of mineralization within the northern part of the existing conceptual open pit.

Holes MQD-25-146, MQD-25-174, MQD-25-175, MQD-25-176, and MQD-25-177 were drilled as 50-meter step outs behind and along strike of the recently discovered mineralized shear in MQD-25-148 (17.6m of 3.03 g/t Au from 76.4m) as reported in the Company’s news release dated March 3, 2025.Each hole intersected a similar package of largely undeformed epidote-chlorite altered diorite containing 2-3% disseminated pyrite with localized strong sericite-silica altered shears containing numerous, highly deformed, cm-scale quartz±carbonate veinlets and 3-5% pyrite-chalcopyrite mineralization.

Multiple parallel shears, often spaced 25 to 50 meters apart, have been intersected with mineralization returning higher grade intercepts of 9.45m of 6.02 g/t Au from 186.0m in MQD-25-175, including 2.45m of 22.2 g/t Au from 193.0m (Figure 3) and 9.0m of 2.30 g/t Au from 117.0m in MQD-25-176, including 3.0m of 9.00 g/t Au from 124.0m. Lesser mineralized intercepts include 3.35m of 0.93 g/t Au from 248.15m in MQD-25-146, including 2.25m of 1.17 g/t Au from 248.75m; 0.7m of 3.57 g/t Au from 350.3m in MQD-25-175; and 3.50m of 2.72 g/t Au from 41.4m in MQD-25-177, including 2.75m of 3.33 g/t Au from 42.15m.

Oriented core measurements collected during the logging process indicate that this shear system trends roughly east-west and coincides with the deeper high-grade intercepts in MQD-22-014 (16.0m of 2.69 g/t Au from 477m, including 5.25m of 7.87 g/t from 477.75m) as reported in the Company’s news release dated May 5, 2022. This implies significant room for the mineralized system to grow through further drilling.

Figure 3: Sericite-silica altered and pyrite-chalcopyrite bearing shears in MQD-25-175 returning 9.45m of 6.02 g/t Au from 186.0m as part of the Superion program following up on MQD-25-148.

Holes MQD-25-149 and MQD-25-150 were drilled approximately 160 meters east of MQD-25-148, testing the up-dip extensions of deeper shears intersected in previous drilling. The holes intersected the same undeformed epidote-chlorite altered diorite body as noted above, with similar sericite-silica altered and sulphide-bearing shear zones. Shearing is of a lesser intensity than that intersected around the core of the Superion discovery and returned intercepts of 4.06m of 1.08 g/t Au from 140.65m in MQD-25-149 and 5.0m of 0.44 g/t Au from 132.0m in MQD-25-150. The wide spacing of drill holes means that zones of stronger shearing may still be present in the area.

Holes MQD-25-161, MQD-25-162, MQD-25-163, MQD-25-164, and MQD-25-168 were drilled on 100- to 200-meter spacings further to the northeast to evaluate a large area of swampy terrain northeast of the Moss deposit that has been mostly untested by previous exploration campaigns. All holes intersected the same undeformed epidote-chlorite altered multiphase diorite body that hosts shears at Superion in addition to narrow, Superion-style, sericite-silica altered shear zones with variable sulphide mineralization. These shears returned high-grade gold-bearing intercepts over narrow widths such as 0.3m of 5.86 g/t Au from 55.85m in MQD-25-163 and 0.9m of 11.9 g/t from 143.0m in MQD-25-168.

Given the broad spacing, a large area of 250 meters by 1,000 meters remains poorly tested and likely contains additional untested shears. Additional drill holes will be planned for later in the year following a thorough analysis of oriented core data and the distribution of the different diorite intrusion phases.

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 Laboratories and CAN-P-4E ISO/IEC 17025. Samples were analysed for gold via fire assay with an AA finish and 48 pathfinder elements via ICP-MS after four-acid digestion. Samples that assayed over 10 ppm Au were re-run via fire assay with a gravimetric finish.

In addition to ALS quality assurance / quality control 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.
