Forward-Looking Statements

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

performance including, the aggregate amount or number of Securities that may be offered pursuant to the Prospectus

and any prospectus supplement; the filing and effectiveness of any potential prospectus supplement; the Company

undertaking any offering of Securities under the Prospectus, including the amount and terms of any Securities to be

offered; the use of proceeds of any offering of Securities; and the Company’s status as one of the fastest growing silver

producers in Mexico.

Such forward-looking statements and information reflect management's current beliefs and expectations 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: the Company’s estimates of mineralized material at El Cubo

and San Ignacio and the assumptions upon which they are based, including geotechnical and metallurgical characteristics

of rock 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; the ability of the Company to ramp up processing of mineralized material at Cata at the projected

rates and source sufficient high grade mineralized material to fill such processing capacity; 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 cost estimates;

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,

availability of financing, future prices of gold, silver and other metals, currency rate fluctuations, rising inflation and

interest rates, actual results of production, exploration and development activities, actual resource grades and recoveries

of silver, gold and other metals, availability of third party mineralized material for processing, unanticipated geological or

structural formations and characteristics, geopolitical conflicts including wars, environmental risks, 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

successfully discover and mine sufficient quantities of high grade mineralized material at El Cubo, VMC, San Ignacio and

3

Topia for processing at its existing mills to increase production, tonnage milled and recoveries rates of gold, silver, and

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

mineralized material from El Cubo, VMC, San Ignacio, Topia and its other mines 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 production of silver, gold and

other metals 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 any resurgence of COVID-19, the ongoing war in Ukraine and conflict in Gaza

and higher 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, supplies, 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 press 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.
