About Goldshore Resources Inc.

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 1 jurisdictions. It is led by the former 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-per-cent-owned Moss gold project, which is positioned in Ontario, Canada, with direct access from the Trans-Canada Highway, hydroelectric power near the site, supportive local communities and a skilled work force. The company has invested over $60-million of new capital and completed approximately 80,000 m of drilling on the Moss gold project, which, in aggregate, has had over 235,000 m 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 grams per tonne (g/t) gold (Au) and 5.20 million ounces of inferred gold resources at 1.11 g/t Au. The MRE only encompasses 3.6 kilometres of the 35-plus-kilometre mineralized trend, remains open at depth and along strike, and is one of the few remaining major Canadian gold deposits positioned for fast-track through this development cycle.
