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 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

2

contingencies. These assumptions include: our estimates of mineral resources and other mineralized material at El Cubo and

the Company’s other mining projects in Guanajuato, Mexico 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 the 2023 Preliminary Economic Assessment on El Cubo (“2023 PEA”); the ability

of the Company to ramp up processing of mineral resources and material at El Cubo and the Company’s other mining projects

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;

operating costs; 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, high 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 mineral resources or other material at El Cubo, VMC, San Ignacio and Topia (including at Topia

buying and processing ore from contractors) for processing at its existing mills to increase production, tonnage milled and

recovery rates of gold, silver, and other metals in the amounts, grades, recoveries, costs and timetable anticipated. In

addition, GSilver’s decision to process mineral resources and other material from El Cubo, VMC, San Ignacio 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 that are not mineral reserves

do not have demonstrated economic viability, are considered too speculative geologically to have 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 or

the 2023 PEA 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 the continued spread and severity of COVID-19, the ongoing war in Ukraine and

high 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 news release are qualified by these cautionary statements and

those in our continuous disclosure filings available on SEDAR at www.sedar.com 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.
