Forward-Looking Statements

This news release contains certain forward-looking statements and information, which relate to future events or future

performance including, but not limited to, GSilver's growth, the merits of Bolantios; the Company's plans and objectives with

respect to Bolanitos, expected closing date of the Acquisition, the satisfaction of conditions associated with the Acquisition and

GSilver's status as one of the fastest growing silver mining company in Mexico.

Such forward-looking statements and information reflect management's current beliefs and are based on information currently

available to and assumptions made by the Company; which assumptions, while considered reasonable by the Company, are

inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These

assumptions include: our estimates of the potential quantity, grade and metal content of the mineralized material at Bolanitos, El

Cubo and San Ignacio, that the parties are able to satisfy the conditions of the Acquisition and close the Acquisition; the

Company to accomplish its plans and objectives with respect to Bolanitos within the expected timing or at all, that the appeal of

the NucTech ruling will be successful, that the new mining fleet will be delivered on schedule, that the new mining fleet will

operate in accordance with design specifications, the geotechnical and metallurgical characteristics of such material conforming

to sampled results and metallurgical performance; available tonnage of mineralized material to be mined and processed; resource

grades and recoveries; assumptions and discount rates being appropriately applied to production estimates; prices for silver, gold

and other metals remaining as estimated; currency exchange rates remaining as estimated; availability of funds for the Company's

projects and to satisfy current liabilities and obligations including debt repayments; capital, decommissioning and reclamation

estimates; prices for energy inputs, labour, materials, supplies and services (including transportation) and inflation rates

remaining as estimated; no labour-related disruptions; no unplanned delays or interruptions in scheduled construction and

production; all necessary permits, licenses and regulatory approvals are received in a timely manner; and the ability to comply

with environmental, health and safety laws. The foregoing list of assumptions is not exhaustive.

Readers are cautioned that such forward-looking statements and information are neither promises nor guarantees, and are subject

to risks and uncertainties that may cause future results, level of activity, production levels, performance or achievements of

GSilver to differ materially from those expected including, but not limited to, risks related to the parties ability to satisfy the

conditions of the Acquisition and close the Acquisition; the ability of the Company to accomplish its plans and objectives with

respect to Bolanitos within the expected timing or at all; market conditions, availability of financing, currency rate fluctuations,

high inflation and interest rates, tariffs, that the appeal of the NucTech ruling is unsuccessful, geopolitical conflicts including

wars, actual results of exploration, development and production activities, actual grades and recoveries of silver, gold and other

metals from the Company's existing mines including El Cubo, San Ignacio, VMC and Topia, that the new mining fleet will not be

delivered on schedule, that the new mining fleet will not operate in accordance with design specifications, availability of third

party mineralized material for processing, unanticipated geological or structural formations and characteristics, environmental

risks, future prices of gold, silver and other metals, operating risks, accidents, labor issues, equipment or personnel delays, delays

in obtaining governmental or regulatory approvals and permits, inadequate insurance, and other risks in the mining industry.

There are no assurances that GSilver will be able to continue to increase production, tonnage milled and recoveries rates, improve

grades and reduce costs at El Cubo, San Ignacio, VMC and/or Topia to process mineralized materials to produce silver, gold and

other concentrates in the amounts, grades, recoveries, costs and timetable anticipated. In addition, GSilver's decision to process

mineralized material from El Cubo, San Ignacio, VMC and Topia is not based on a feasibility study of mineral reserves

demonstrating economic and technical viability and therefore is subject to increased uncertainty and risk of failure, both

economically and technically. Mineral resources and mineralized material that are not Mineral Reserves do not have

demonstrated economic viability, are considered too speculative geologically to have the economic considerations applied to

them, and may be materially affected by environmental, permitting, legal, title, socio-political, marketing, and other relevant

issues. There are no assurances that the Company's projected grades of gold and silver at El Cubo and San Ignacio and the

anticipated level of production therefrom will be realized. In addition, there are no assurances that the Company will meet its

production forecasts or generate the anticipated cash flows from operations to satisfy its scheduled debt payments or other

liabilities when due or meet financial covenants to which the Company is subject or to fund its exploration programs and

corporate initiatives as planned. There is also uncertainty about impact of any future global pandemic, ongoing global military

conflicts, elevated inflation and interest rates and the impact they will have on the Company's operations, supply chains, ability to

access mining projects or procure equipment, contractors and other personnel on a timely basis or at all and economic activity in

general. Accordingly, readers should not place undue reliance on forward-looking statements or information. All forward-looking

statements and information made in this news release are qualified by these cautionary statements and those in our continuous

disclosure filings available on SEDAR+ at www.sedarplus.ca including the Company's most recently filed annual information

form. These forward-looking statements and information are made as of the date hereof and the Company does not assume any

obligation to update or revise them to reflect new events or circumstances save as required by law.
