Goldshore Expands Environmental Data Collection to Support Permitting Process

VANCOUVER, B.C., April 02, 2025: Goldshore Resources Inc. (TSXV: GSHR / OTCQB:

GSHRF / FWB: 8X00) (“Goldshore” or the “Company”), is pleased to provide an update on its

ongoing environmental data collection at its 100%-owned Moss Gold Project located in Ontario,

Canada (the “ Moss Gold Project ”). In preparation for permitting activities, Goldshore has

significantly increased the collection of vital environmental data through several ongoing work

programs, including the following:

 Expanded the surface water flow and water quality sampling network in key streams

and lakes across the project area that commenced in mid-2021 to ensure a

comprehensive understanding of the pre-mining state of the natural watercourse system.

Stream measurements will continue on an ongoing basis, building on almost four years of

continuous data, to ensure a complete and comprehensive baseline through exploration,

environmental assessment, construction, mining and mine closure.

 Commenced drilling of water bores in the proposed open pit area, along with packer

testing, and nested water well pairs in proposed infrastructure sites to provide a

comprehensive dataset used to generate a numerical water model of the groundwater

system. These data will inform the needs for water management that will be reviewed

during a future Feasibility Study. This program will be completed in 2026.

 Completed a seismic geophysics survey over the proposed open pit area that,

together with exploration drilling logs, will enable the creation of an accurate 3D model of

the glacial till overburden covering the Moss Gold Deposit. The model will be delivered in

Q2 2025. Further seismic surveys will be conducted over the proposed tailings

management facility site.

 Expanded aquatic and terrestrial biology studies, including fisheries, wetlands,

small mammals and waterfowl. This is part of a two-year program that will be completed

by the end of 2026 and reported on in early 2027. It will inform discussion with potentially

affected Indigenous communities on, among other items, fisheries and wetlands offset

agreements.

 Commenced environmental geochemical characterization of waste and mineralized

rock types through static and kinetic test work. Initial work will continue for the next

three to four quarters with the goal of understanding whether the different rock types have

the capacity to generate acid and, if so, what mitigation measures could be applied during

potential future mining operations. The Company notes that approximately 50,000 tonnes

of historical mineralized rock that was left on site by explorers in the 1980s has not

generated any environmental concerns, even after forty years.

 Commencing Stage 2 archaeological field studies along with members of

potentially affected Indigenous communities in Q2 and Q3 2025. The Company notes

that the Stage 1 desktop study, completed in 2021, did not identify any known sites.

Michael Henrichsen, CEO of Goldshore commented, “The Company is encouraged by the

growing political and public recognition of the need for regulatory efficiencies to support

responsible resource development. Recent provincial and federal discourse has emphasized the

importance of streamlining approval processes for major projects in order to reduce duplication,

address prevailing inefficiencies, and respond to broader economic challenges. In this context,

the Company’s ongoing environmental and geotechnical data collection will help ensure it is well-

positioned to advance the Moss Gold Project responsibly and efficiently within the evolving

political and regulatory landscape. Regardless of any forthcoming regulatory changes, Goldshore

will continue to prioritize its relationships with potentially affected Indigenous communities to

ensure that the project is being developed in a robust and responsible manner.”

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 $60

million of new capital and completed approximately 80,000 meters of drilling on the Moss Gold

Project, which, in aggregate, has had over 235,000 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. Please see NI 43-101 technical report titled: “Technical Report and

Updated Mineral Resource Estimate for the Moss Gold Project, Ontario, Canada,” dated March

20, 2024 with an effective date of January 31, 2024 available under the Company’s SEDAR+

profile at www.sedarplus.ca. For more information, please visit SEDAR+ (www.sedarplus.ca) and

that events or conditions “will,” “would,” “may,” “could” or “should” occur. Forward-looking

statements in this news release include, among others, statements relating to expectations

regarding the exploration and development of the Moss Gold Project; the potential mineralization

at the Moss Gold Project based on the winter drill program, including the potential for additional

mineral resources; the enhancement of the Moss Gold Project; statements regarding the

Company’s future drill plans, including the expected benefits and results thereof; that the Superion

target has the potential to significantly add to the current mineral resource estimate within the top

200 meters from surface with continued drilling and to reduce the overall strip ratio of the deposit;

the potential for resource growth at Moss and the fact that the results have the potential to

significantly impact the economic performance of the deposit moving forward; the potential for a

much larger mineralized system and that it will be pursued in the near future through

additional drilling; and other statements that are not historical facts.

By their nature, forward-looking statements involve known and unknown risks, uncertainties and
