Guanajuato Silver Reports Q1 2023 Financial and Operating Results

~ Q1 Production of Over 938,000 AgEq Ounces ~

May 26, 2023 – Vancouver, British Columbia – Guanajuato Silver Company Ltd. (the “Company” or “GSilver”)

(TSXV:GSVR)(AQUIS:GSVR)(OTCQX:GSVRF) is pleased to announce financial and operating results for the three

months ended March 31, 2023. All dollar amounts are in US dollars (US$). Production results are from the

Company’s wholly owned El Cubo Mines Complex (“El Cubo”), Valenciana Mines Complex (“VMC”) and San

Ignacio mine (“San Ignacio”) in Guanajuato, Mexico, and Topia mine ("Topia") located in Durango, Mexico.

James Anderson, Chairman & CEO of Guanajuato Silver, said, “We continue investing agressively in our assets

as we build what we feel is Mexico’s fastest growing silver mining company. Operating results for Q1 continue

to demonstrate growth and are aligned with our expectations for this phase of the ramp-up; I commend our

100% Mexican operations team for their technical excellence as we optimize production at all four of our

producing silver mines. With quarter-over-quarter increases in silver-equivalent production expected to

continue, we remain on-pace to meet our stated full year production guidance of 4.6 to 4.8 million silver-

equivalent (“AgEq”) ounces in 2023. We expect to end 2023 at a production run-rate of over 5 million AgEq

ounces per year.”

Q1 2023 Highlights

• Record production during the quarter of 938,047 AgEq ounces derived from 458,803 ounces of silver;

4,413 ounces of gold; 906,696 pounds of lead; and 1,153,138 pounds of zinc.

• Record Revenue of $17.1M, up from $15.4M in Q4 2022; revenues grew from increased production of

AgEq ounces, as well as higher realized silver and gold prices during the quarter.

• Net Loss narrowed to $8.7M from $9.9M in Q4 2022.

• Reduced environmental footprint through the implementation of an underground hydraulic-fill tailings

system at VMC; tailings material is now being placed underground in some of the numerous voids that

have been created over VMC’s 450-year mining history.

• All-in sustaining cost (“AISC”) of $21.83 per AgEq ounce produced was slightly higher than $20.80 for

Q4 2022; this increase was due primarily to targeted capex investments designed to accelerate the

ramp-up of operations at the three Guanajuato mines; operating costs were also impacted by a

strengthening Mexican currency as approximately 75% of operating costs are denominated in pesos.

• Infrastructure upgrades are poised to deliver substantial improvements in 2023; these upgrades

include:

 The new Falcon concentrators at El Cubo and VMC are now fully operational and set to generate

improvements to precious metal recoveries going foward.

 The Cata shaft at VMC has been rehabilitated and is now fully operational; over 300 tonnes per

day of mineralized material is now moving through this shaft which has reduced the time to

move material to surface by approximately 80%.

 The implementation of hydraulic backfilling of tailings at VMC has allowed for an acceleration

in the operations at the Cata mill.

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 projected continued quarter-over-quarter increases in AgEq production

and stated 2023 full year production guidance and year end production run-rate of AgEq ounces, GSilver’s anticipated

reduced environmental footprint resulting from its implementation of an underground hydraulic-fill tailings system at VMC,

the expected improvements in production to be derived from the stated infrastructure upgrades at El Cubo and VMC, the

ability of the Company to continue to increase production, tonnage and recoveries of mineralized material at San Ignacio,

Valenciana, El Cubo and Topia in accordance with its objectives and timetable including increasing silver and gold grades,

improving metallurgical recovery rates, increasing revenues, and reducing production costs (including AISC) consistent with

the Company’s expectations and production model, the Company’s future development and production activities, and

what we feel as 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: the potential quantity, grade and metal content of the mineralized material at

El Cubo, San Ignacio, VMC and Topia, the geotechnical and metallurgical characteristics of such material conforming to

4

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,

availability of financing, currency rate fluctuations, high inflation and interest rates, geopolitical conflicts including wars,

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

and other metals from the Company’s existing mines including El Cubo, 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 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, San Ignacio, VMC and Topia 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 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, 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 annual information form for

the fiscal year ended December 31, 2021. 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.
