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, statements and information

regarding future plans, expectations, guidance, projections, objectives, estimates and forecasts; including

statements regarding Mr. Pax ton’s expected contributions; plans to fully optimize all the Company’s

Mexican mining projects; growing the Company into a leading mid -tier precious metals producer ; and

GSilver’s status as one of the fasting 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: that the potential

quantity, grade and metal content of the mineralized material at Bolanitos, El Cubo, VMC and San Ignacio,

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, market conditions, the ability of the Company to accomplish its plans and

objectives with respect to Bolanitos within the expected timing or at all; availability of financing, currency

rate fluctuations, high inflation and interest rates, 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 Bolanitos, El Cubo, Pinguico, San Ignacio, VMC and

Topia, 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 Bolanitos, El Cubo, Pinguico, 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 Bolanitos, El Cubo, Pinguico, San Ignacio, VMC and Topia is not based on a

4

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

Bolanitos, El Cubo, VMC 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 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.
