Vancouver, British Columbia - Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) ('Goldshore' or the 'Company') is pleased to announce its latest assay results from its recently completed 20,000-meter drill program targeting new mineralized shear zones to the north of the QES zone as part of the follow up drilling from the discovery of the Superion zone at the Moss Gold Project in Northwest Ontario, Canada.

Michael Henrichsen, CEO of Goldshore commented, 'Additional drilling to the west of the Superion discovery continues to deliver new mineralized shear zones on the northern side of the QES Zone within or near the conceptual open pit. We believe the definition of these new mineralized zones clearly demonstrates the emerging nature of the deposit as we continue to expand mineralization. In addition, the higher-than-average resource grades that have been encountered thus far on the northern side of the pit are very encouraging and will be a focus for additional drilling in the future, as we look to define a near surface high-grade zone that could be accretive to the economic performance of the deposit.'

Highlights

Results from a series of holes testing an undrilled area between and on the northern flank of the QES and Main zones have intercepted multiple new mineralized shears within the existing conceptual pit. Best intercepts include: 10.35m of 0.59 g/t Au from 109.0m in MQD-25-178 and 6.0m of 1.14 g/t Au from 138.0m, including 3.0m of 1.73 g/t Au from 138.0m, and 15.4m of 0.64 g/t Au from 239.6m, including 4.0m of 1.44 g/t Au from 246.0m

17.7m of 1.52 g/t Au from 333.0m in MQD-25-179, including 2.3m of 8.24 g/t Au from 334.0m and 4.0m of 1.27 g/t Au from 346.0m, and 6.85m of 3.01 g/t Au from 436.0m including 2.0m of 9.76 g/t Au from 436.0m

22.0m of 0.48 g/t Au from 185.0m in MQD-25-180, and 18.4m of 1.36 g/t Au from 285.6m, including 10.75m of 2.01 g/t Au from 293.5m

Results from the most northern step back hole, MQD-25-179, intersected the Superion mineralized trend extending the strike length to 380m with an intercept of: 13m of 0.84 g/t Au from 35m in MQD-25-179, including 2.00m of 3.84 g/t Au from 44.0m

Technical Overview

Drill results reported herein are from the Superion exploration drill program, targeting a significant and largely untested area beneath swampy terrain on the north side of known mineralized shears within or near the conceptual open pit defining the Moss deposit.

MQD-25-178 was drilled approximately 300m west of the newly discovered Superion Zone. The hole collared into a porphyritic diorite before transitioning into a multi-phase diorite complex like that of the Main Zone host rock. The diorites are variably altered, changing between chlorite-epidote to sericite-silica-hematite to sericite-chlorite dominated assemblages, all of which contain 2-3% disseminated pyrite. Shear zones are altered with sericite-silica-hematite and sericite-chlorite assemblages and mineralization locally increasing to 3-5% pyrite. They yield intercepts of 10.35m of 0.59 g/t Au from 109.0m, 6.0m of 1.14 g/t Au from 137.0m including 3.0m of 1.73 g/t Au, and 15.4m of 0.64 g/t Au from 239.6m including 4.0m of 1.44 g/t Au from 246.0m.

MQD-25-179 was drilled as a 160m step back behind MQD-25-178. The hole collared into andesitic volcanics and transitioned to dacite volcanics at 39.0m where the contact is strongly sheared with Superion-style sericite-silica alteration containing highly deformed quartz-carbonate veining and 3-5% disseminated pyrite-chalcopyrite mineralization, which yielded an intercept of 13.0m of 0.84 g/t Au from 35.0m, including 2.0m of 3.84 g/t Au from 44.0m. Two shearing fabrics were measured in the area, an east-west-striking fabric, in line with the Superion mineralization trend, and a northeast-southwest-striking fabric following the main deposit trend. It is unclear at this point which trend is controlling mineralization. The hole continued in dacitic volcanics until 263.0m intersecting the same multi-phase diorite complex as described in MQD-25-178. Shear zones are altered with sericite-silica-hematite and sericite-chlorite alteration packages hosting 3-5% disseminated pyrite-chalcopyrite mineralization and yielding multiple intercepts including 17.7m of 1.52 g/t Au from 333.0m including 2.3m of 8.24 g/t Au from 334.0m and 4.0m of 1.27 g/t Au from 346.0m, 6.1m of 0.66 g/t Au from 362.0m, and 6.85m of 3.01 g/t Au from 436.0m including 2.0m of 9.76 g/t Au from 436.0m.

About Goldshore

Goldshore is a growth-oriented gold company focused on delivering long-term shareholder and stakeholder value through the acquisition and advancement of primary gold assets in tier-one jurisdictions. It is led by the ex-global head of structural geology for the world's largest gold company and backed by one of Canada's pre-eminent private equity firms. The Company's current focus is the advanced stage 100% owned Moss Gold Project which is positioned in Ontario, Canada, with direct access from the Trans-Canada Highway, hydroelectric power near site, supportive local communities and skilled workforce. The Company has invested over $75 million of new capital and completed approximately 100,000 meters of drilling on the Moss Gold Project, which, in aggregate, has had over 255,000 meters of drilling. The 2024 updated NI 43-101 mineral resource estimate ('MRE') has expanded to 1.54 million ounces of Indicated gold resources at 1.23 g/t Au and 5.20 million ounces of Inferred gold resources at 1.11 g/t Au. The MRE only encompasses 3.6 kilometers of the 35+ kilometer mineralized trend, remains open at depth and along strike and is one of the few remaining major Canadian gold deposits positioned for development in this cycle.
