Forward-Looking Statements and Information

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

including, but not limited to, the size of the Offering, the intended use of proceeds therefrom and the anticipated closing date

thereof, the Company’s future development and production activities and opportunities for future exploration, development

and production and the estimated timing and costs thereof; and the status of the Company 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, market, economic and regulatory

uncertainties and contingencies. These assumptions include: our mineral resource estimates at El Cubo, El Pinguico 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 e stimates; the ability of the Company to successfully integrate production from San Ignacio and Valenciana into

the Company’s existing mining and milling operations at El Cubo and the availability of excess processing and tailings

capacity at El Cubo to accommodate same; the Company’s ability to secure additional sources of mineralized material for

processing, 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 expenditures, 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; a ll 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 significant risks and uncertainties that may cause actual future results, level of activity, production levels,

performance or a chievements 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, actual results

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

metals, availability of third party mineralized material for processing, rising inflation and interest rates, geopolitical conflicts

including wars, unanticipated geological or structural formations and characteristics, 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 the Company will

successfully complete the Offering in whole or in part on the terms and in accordance with the timing set out herein.

Further, 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 its existing mines to process mineralized materials to produce silver, gold and

3

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

mineralized material from its mining projects 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

the impact of any future global pandemic, ongoing global conflicts, 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 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.
